Reflashing Tool for Joggler

Latest Release: 5th February 2012

Download System v1.07 – (99MB) MD5

Download Reflash Script v1.11 – (11KB) CHANGELOG


The O2 Joggler is a great device. It’s useful, hackable, affordable and fun. However, there’s always the possibility that the fun might go too far and leave you with a Joggler that’s not as happy as it should be. So here’s a recovery tool that should bring it back to life.

This is designed to be a robust method of restoring and reflashing the O2 Joggler to its factory defaults, even in the event that the internal flash memory has had it’s partitions destroyed. The Joggler is remarkably robust and will continue to boot from external USB devices even when the internal memory has given up, so unless you have a hardware failure or EFI problem this should get things working again. It also resets the Joggler’s NVRAM in case there’s anything suspicious hiding in there.


  • This software was tested on three Jogglers which display the O2 logo on boot. If your Joggler displays the OpenPeak logo your mileage may vary, although in theory there is no difference between units regarding the contents of the 1GB internal flash memory. If you have an OpenPeak logo Joggler, I’d appreciate a comment on your success (or otherwise!). This software is used entirely at your own risk.

Instructions

The quick version is:

  1. Download the reflashing system from the link above and write it to a USB device of at least 512MB capacity.
  2. Download the latest reflashing script and copy it to the reflash directory on jog-boot.
  3. Add the original OpenPeak O2 image to the reflash directory on jog-boot (optional).
  4. Power off your Joggler and insert the USB stick into the side socket. USB hubs are not advised.
  5. Power on your Joggler and watch.

It is very important that you use good quality USB memory.
If your Joggler fails to boot or shows odd errors, try another USB device.

Updating

To update the reflashing script, just replace the jogglerflash.sh file in the reflash directory with the latest version. Easy!

Part 1: Create the Reflashing Device

Download the latest version of the reflashing system from the link above and follow the instructions for your operating system.

Linux

Open a Terminal window and run sudo fdisk -l to find your device name. Then:

sudo umount /dev/sdX*
gzip -dc lucid-3.1.9joggler1-r107.img.gz | sudo dd of=/dev/sdX bs=1M

Where sdX is your USB device.

Mac OS X

Open a Terminal window and run sudo diskutil list to find your device name. Then:

sudo umount -f /dev/diskX*
gzip -dc lucid-3.1.9joggler1-r107.img.gz | sudo dd of=/dev/rdiskX bs=1m

Where diskX is your USB device.

Windows

These instructions are untested and stolen from here.

Download Win32DiskImager, then unpack the .img.gz file using a tool like 7-zip. Run W32DiskImager.exe, and select the unpacked .img file. Choose the drive that corresponds to your USB stick and use ‘Write’ to write the image.

Part 2: Add the Script and Firmware Image File

Download the reflashing script and copy the file into the reflash directory of the jog-boot volume on the USB device. If you have just written the reflashing system to the device, you may need to unplug and reconnect it before the drive will mount.

If your Joggler does not have a wired network connection plugged into the back with access to the internet, you also need to download this file from OpenPeak:

http://o2.openpeak.co.uk/firmware/app-o2flash-26635.8686-S3-f1-reimage.tgz

Again, copy the file into the reflash directory on the USB device. Do not open or rename the file.

Windows Users: Please note that some versions of Internet Explorer will rename the .tgz file to .gz after downloading it. You’ll need to rename it back to .tgz for the file to be recognised.

Part 3: Boot the Joggler

Make sure the Joggler is powered down and connect the USB device to the socket on the side. Avoid using USB hubs and extension cables, as these have been known to cause problems. The Joggler should display your boot logo before changing to:

Booting ‘Ubuntu Lucid – 3.1.9joggler1’

After a few moments the screen will talk you through the automated process.

How Does It Work?

The reflashing system is a debootstrapped version of Ubuntu Lucid (10.04) running with one of Jools Wills’ Joggler kernels. On startup a script is triggered, which checks for the existence of the OpenPeak reimage file. If it’s there it gets checksummed, if not it gets downloaded and checksummed. Then the internal memory is checked, repartitioned if necessary, and the flashing process begins using Partimage. OpenPeak provide an early version of Partimage (complete with typos!) in the reimage file, so that’s the one we’re using.

Hopefully everything goes fine and the Joggler will shut down, ready for you to disconnect the USB device and power it back up.

Troubleshooting

If everything doesn’t go fine, here are the common faults:

“The reflash system doesn’t boot properly.”

So long as you see a boot logo (O2 or OpenPeak) on screen when you turn on the Joggler, it’s likely that you just need to use a different memory stick. Most (but not all) will boot the Joggler, but then it’s important that the stick be robust and of good quality, otherwise the process will fail later on.

If you’ve tried a couple of alternative USB sticks and the Joggler still won’t boot (but displays a boot logo) you will need to explicitly tell it where to boot from. This can only be done using a USB keyboard and hub.

  1. Attach a keyboard and your memory stick to the Joggler through a USB hub. Powered hubs are best, but you may have success if your keyboard has a built-in hub.
  2. Turn on your Joggler and immediately begin pressing ESCAPE repeatedly for around 10 seconds.
  3. Type fs0: and press RETURN. You won’t see any text on screen.
  4. Type boot.nsh and press RETURN.

With luck, the reflashing system should fire up. If nothing happens, try again. If nothing continues to happen, try fs1:, fs2:, etc. You may need to power off between attempts. Alternatively, try swapping around the order of devices on your USB hub or try another hub.

If you see no boot logo when powering on, you may have a fault with your EFI chip. There’s no fixing this without having a second working Joggler and nerves of steel. You will need to read ‘Recovering a Bricked EFI’ on the wiki.

“It just says ‘Stalling for network…’ and doesn’t get any further.”

This happens when you don’t have a wired ethernet connection plugged into the back of the Joggler, or the Joggler isn’t being given an address from a DHCP server. If you scroll up to ‘Part 2: Add the Script and Firmware Image File’ and follow the instructions, the Joggler doesn’t need a network connection and won’t wait for one to become available.

Version 1.04 of the reflashing system has had some changes made to make the network detection more robust. Hopefully all issues with this have now been resolved.

“It was working, but the screen’s gone blank!”

Don’t panic! Your reflash is just taking a bit longer than expected and the screensaver has kicked in. If things seemed to be going fine, just let it run until the Joggler powers down and the light on your USB stick goes out. Turn off your Joggler, disconnect the USB stick and power back up.

In recent versions the reflashing script turns the screensaver off, so you shouldn’t see this issue any more.

“It seemed to work, but I’m still stuck on the boot screen!”

Pop the USB key back into your computer and create a file in the reflash directory called repart. This will tell the script to recreate all of the partitions, even if it believes that it doesn’t need to be done. Eject the stick and use it to boot your Joggler again.

Interestingly, there are some Jogglers that will store the image perfectly, but still refuse to boot from their internal flash memory. Why this should happen is still a mystery, but if you have any insight, please let me know!

In the meantime, it might be worth looking at some of the other operating systems you can run on your Joggler, as a fix for this particular issue has not yet been found.

“It keeps trying to install an update and never stops rebooting!”

This happens on some Jogglers because of a response from OpenPeak’s servers when they look for updates. Why it happens on some and not on others is a bit of a mystery. However, there is an easy fix; with the kind donation of a misbehaving Joggler by Mr_Dave on the Joggler Forum, I have been able to create an update disabler (and re-enabler). Pop the files on a USB stick and allow the Joggler to reboot one more time.

“I can’t use SSH on my Joggler after reflashing.”

The reflash returns your Joggler to a completely factory-fresh state, so SSH will not be active. I created an SSH and SCP enabler which will get things working again.

I have followed these instructions but my Joggler is currently displaying ‘Stalling for network…’ and has been for some time. Any ideas?

Ashley Giles left this message 372 days ago

Thank you very, very much for this. A bricked Joggler from eBay and I used your reflash and up it came. I couldn’t do it with the wired connection although it worked flawlessly when I copied the image file into the image directory.
One happy person. Thank you. Louis

lou1z left this message 372 days ago

Ashley, I had the same issue. Simply copy the downloaded Joggler image into the image directory on the USB stick you are using to reflash. It takes about 5 mins and you will be back up and running with the original software.

lou1z left this message 372 days ago

@lou1x Fantastic! First Joggler saved! :) Did you buy one of the ‘spares or repairs’ ones I’ve seen on there recently? I’ve been tempted to get another for testing…

@Ashley I’ve replied to your message on the forum.

Andy left this message 371 days ago

I got it off eBay advertised as it wouldn’t boot the native OS but I wasn’t that bothered as I wanted it to run squeezeplay as I have another 5 devices in the home. I tried JoliOS which was OK but you needed a mouse etc for it so I looked around to see if I could get the native OS up and running and here I am. There’s not a lot of places about that do this so your blog is very valuable.
I actually like the native OS as it’s easier to use without a mouse. Now that I can get squeezeplay on it, I might just stick with the original. It’s a pity it doesn’t show photo’s, video’s etc of network drives rather that just the USB. I think I’m going to sit this in one of my bedrooms with some audio engine powered speakers and try to use it as as squeezebox, alarm clock and picture frame etc so I may consider another one if it all works out.

lou1z left this message 370 days ago

Thanks very much for this. My Joggler is back in the land of the living. I had tried so many other solutions all of which had failed. Yours worked first time. Well second time. The first time the screen went black and I assumed it must have finished so I removed the USB and a sort of screen dump crash report came up. I think it must have just gone black like a screen saver. If I had left it a bit longer it would probably have worked. Second attempt I used a USB hub with a keyboard attached and occasionally pressed a key. Don’t know if that was coincidence but the display stayed on throughout the reflash and all went perfectly.

Mike left this message 370 days ago

@Mike Great stuff – glad to hear another one is back to life! Yes, the display does timeout after a while, although I’ve never had that happen on my test units. I should add that to the troubleshooting section.

@lou1z Thanks for the info. Your plan sounds good, hope it goes well!

Hi, good stuff, and nice website!
Have you ever tried to make ZoneMinder or such kind of webcam server working on Joggler ?

Lynx left this message 368 days ago

Excellent work. Just used this on 2 Jogglers – 1 just to clean up and the other I’ve never been able to boot into the stock OS, I’ve tried various other restoration methods without avail, this worked flawlessly, nice one, thanks.

Liam left this message 367 days ago

@Lynx Thanks very much! :) As for ZoneMinder, I’d not heard of it before, but it looks like a nice system. If you grabbed a copy of Ubuntu for Joggler (check the forum – all the info is there) then you should be able to install and run it.

@Liam Superb – it’s great to hear! I don’t suppose either of your Jogglers boot with the OpenPeak logo, do they? I’m yet to hear from someone using one of those models and would be very keen to know that it works.

I am also getting Stalling for network, and I have both the image file in the image folder and a wired connection, any suggestions?

Thanks for the O2 Joggler fix.
I bricked my O2 Joggler months ago, turning it off while it was playing Audio, and couldn’t be arsed to send it back to O2, knowing it was just a file corruption problem.

Just tried it, and rebooted.
Waited a few minutes, O2 Logo, waited a few more minutes, black screen, and then finally…. An O2 user details home screen :)

You are an absolute STAR!!!!!!

Help! Reflash 1.03 worked great on 3 jogglers (with up-to-date fware), but only if image put on usb (not from net). BUT TIME DOES NOT SET! On 1st reboot,
Jogglers request 1st page of registration – but not things like “name or joggler”…
They all now work fine BUT time does not get set – very frustrating!
An unflashed joggler will prevent the command “ntpdate uk.pool.ntp.org” from native linux because “ntp in use”, but a flashed one allows this. So maybe other things are not running after flashing as well as time. I believe it’s connected to incomplete initial registration.
Please help

weeblies left this message 364 days ago

@Psionguy Try a different memory stick – it sounds like there’s a problem with the reimage file you downloaded, otherwise it wouldn’t be waiting for a network connection. If that doesn’t work, please ask on the forum.

@Jay Hooray! :)

@weeblies Interesting. I shall investigate.

Andy left this message 362 days ago

The issue with NTP has now been resolved in v1.04. Instructions for updating the flashing system are included above.

For those that have already reflashed, instructions will be appearing in the article tomorrow.

EDIT: Instructions are in the Troubleshooting section now!

Andy left this message 362 days ago

Hi,

I have 3 Jogglers. 2 of them are running Squeezeplay perfectly. I can’t enable telnet access on the third because none of the USB ports work. I have also tried the 2 additional internal ports available on the PCB, but I still can’t get it to boot the stick. I know the stick is fine because it works on my other Jogglers.

This is really annoying because everything else (not wi-fi) works fine.
So is there another way to activate telnet?

I was thinking there might be a way to use the update program in the OS to get it to download and execute a custom script. If I run a wireshark session I should see the URL and filename it tries to download during the update. Once this is found I would only need to add this domain to my local DNS server and point it to a local web server containing the custom script.

I think this should work, but I don’t have a clue about how the Joggler updates work.

Does anyone know how this works?

Many thanks

Many thanks for all the info.
Suddenly stopped working (suspect power spike) 30 minutes later all good again.
Kept waiting for the network connection despite having the image in the reflash folder.
Copied the filename from the script and renamed image.

Once again many thanks for the clear and concise instructions.

MT left this message 340 days ago

I think some of the correspondents above may have had the same problem I had. Download the image that goes in the reflash directory using firefox, Explorer changes the file and the script doesnt see it, renames from tgz to gz extension. Firefox leaves as is. I had the “stalling” problem until I did that.

edupit left this message 338 days ago

Wow this is brilliant – my joggler died a few days ago after a power cut and wouldn’t boot up beyond 02 screen. I found this webpage and now its all working again. Only problem I had was my joggler couldn’t find network, so I installed the openpeak flash onto the USB drive, then it still wouldn’t work. Reading through the thread I soon realised my browser had changed the .tgz file to .gz – I put it right and its now running perfectly and all setup with apps as I had it before – Thank You….

Brian left this message 338 days ago

Just reflashing again…. ! I tried to install the new Iplayer update from Spoyser in the forums, but after modifying the applications.xml file (correctly I think as I didn’t omit the slash and cat applications.xmil looks OK) all of the icons disappeared. I had squeezeplayer installed however, so just going to try Iplayer again on it’s own before installing squeezeplayer, and I will leave the USB stick reflashed so I can get back into the stock image straight away if it all goes pear shaped.

Thank you roobarb and thank you Bejeezus; my joggler was knobbled by a power cut ages ago and I couldn’t get anything to boot properly till I found this site. But alas still no joy, tried different sticks and a powered hub no no avail. Eventually stumbled on a post on the forum that used 2 sticks and bizarrely it worked first time. No idea why but hey….

Simon left this message 319 days ago

Thank you so much! Managed to corrupt the 2nd or 3rd partition of the flash by mapping them to the android SD card and formatting. It wouldn’t boot past the O2 screen, even when following your instructions with the special USB image.
However, I found another forum post which worked for me – stick tghe USB key into the first port of a hub and a keyboard into the second. For me the hub had to be unpowered even though it was capable of its own power supply. I then hit ESCAPE lots of times after powering on the joggler, then typed (blindly) “fs0:”<enter> and then “boot.nsh” <enter> This then got me booting into your recovery procedure. Hope this helps anyone with similar symptoms

You saved my Joggler! All worked perfectly on Win 7 ×64. (One note about Image Writer – I found that the .img source file needs to be in a root directory otherwise Image Writer gives an error when trying to write it to USB). Thanks for all the time and effort you’ve clearly put in.

Andrew left this message 274 days ago

Thanks, worked fine over network to recover a friends Joggler. Will use it later to ‘factory fresh’ one of mine that gets hacked a lot.

One odd thing, when I tried to download the image file with my PC (Win XP /IE8) I ended up with a ‘.gz’ file but the same URL fetched a ‘.tgz’ file using wget on my linux box. Then tried Chrome on XP and it got the ‘.tgz’ file, so did a bit of googling and apparently this is a common problem with IE. You may wish to add a comment in the PC section.

Hi everyone, I bricked my Joggler trying to get it to do a manual update as it wouldnt do one on its own (its a replacement from O2 for one that failed).

w1ndrush left this message 244 days ago

When you write copy the files to the “reflash” folder, I take it you mean on linux-root partition and not linux-boot? It’s confusing that “reflash” folders exist on both partitions

Alasdair left this message 244 days ago

@Lynx Ooh, dear. That looks to me like the internal memory may have passed away. What happens in that last stage is that the reflash system tries to mount one of the newly restored partitions and use a utility to clear the NVRAM settings. The mount command is failing to identify the filesystem type on the partition, which means it is probably corrupt.

Does the reflash tool attempt to recreate the partition information every time it is run? If not, try editing line 124 of jogglerreflash.sh (v1.06) to read:

mount -o ro /dev/mmcblk0p3 /mnt

Then try it again. Good luck!

@w1ndrush Perhaps you are the only one following the instructions properly! That is my mistake – jogglerflash.img.gz was replaced by ubuntuserverlucid.img.gz some time ago. I have updated the instructions.

@Alasdair Nope, I mean linux-boot. The ext2 filesystem doesn’t (ordinarily) mount under Windows, so those users don’t see the other reflash directory. I will update the instructions.

I have tried it on my openpeak version.

Works perfectly UNTIL i connect to network and it loops through:

Until I remove network.

Arm5 left this message 231 days ago

@Arm5 This has been seen before, but to the best of my knowledge we’ve never entirely got to the bottom of it. I’ve never managed to provoke a Joggler into producing this reboot loop, so it’s been impossible for me to experiment.

Take a look on the forums and ask around in there – perhaps we can get to the bottom of it this time.

Andy left this message 231 days ago

I’ve used this tool twice on other jogglers with tremendous success. Thanks.
The third one I tried was one previously stuck on the O2 logo at boot. The tool reflashes the joggler fine, prompts for reboot. But then on boot up gets stuck on O2 logo and makes no further progress.

Tried a variety of keys – which I know have worked in the past. Any ideas?

When my Joggler ‘died’ and just showed the O2 logo, I did some Googling and feared it was most likely the EFI chip issue. As I don’t know anyone else with a Joggler and I can’t afford to get another one, I guessed that was that.
Then I found your site and having just followed the instructions, I’m pleased to say my Joggler is revived and once again has pride of place on the shelf.
Thanks so much for these instructions and your wonderful script.

Andy left this message 205 days ago

just about to try reflashing but not really sure that it will solve my problem – recently my Joggler (openpeak tango) has started having screen problems – the screen just goes black every couple of seconds – as soon as I touch it it comes back to life and everything seems to be working – take my finger off and it goes blank again – do you think the reflash will help?

Susan McInnes left this message 205 days ago

That’s interesting – it does sound like a software issue to me, as there’s nothing I can think of in hardware that would cause a problem like that (except for a bad internal connection).

Does it only turn the screen back on when you touch the image part of the screen? For example, it doesn’t come back when you touch or squeeze the black sides? The first points to software, the second to hardware. If it’s hardware it shouldn’t be a complicated repair; if it’s software, give this reflash tool a try.

Andy left this message 204 days ago

Went for it and used your tool and it is miraculous (sp?) My Joggler is just like new now so can start to play around with it. It has been on for a while now and the screen has remained lit.

Andy, thanks very much for this. :) My brother-in-law’s Joggler stopped working one day and so I thought this was worth a try and it worked perfectly. First time didn’t work but I tried another USB stick and it was fine.

@Dave – I first tried an 8GB Dane-Elec which failed with the ‘no such partition’ error. I then tried a 4GB Integral which worked fine. I would have thought the Dane-Elec to be a superior stick but maybe that doesn’t have any bearing in this scenario.

Having problems getting this tool to work on my Joggler. I insert USB to Joggler and boot up. O2 screen shows for few seconds before the Ubuntu screen kicks in. Semms to start to do what it’s supposed to do, but then the Joggler screen goes off part way through & Joggler shuts down. The only way to get it back is to reboot.

@Joggler User That sounds odd. Is the Joggler really shutting down (do you get shutdown messages on the screen), or is it just the screensaver kicking in. It shouldn’t be (I’m pretty sure it’s disabled), but worth an ask.

The best way to diagnose is if you could make a quick video of the issue and post it somewhere, unless you can make note of any error messages that appear.

No shutdown messages. Seems to do everything ok until the ‘waiting to settle’ screen. Then starts to load/unzips the files with a list starting to scroll down the screen but within a few seconds, powers off completely. No lights flashing on the USB drive etc. Have done this few times, sometimes leaving the Joggler alone to stand in this condition overnight. Just to mention, I can get XP to work on the Joggler without any problems.

@Joggler User What size memory stick are you using, and have you tried any others? It sounds like it’s having problems decompressing the files, because other than the information it gives when the data is being written, there shouldn’t be a file-list scrolling down the screen.

If you have any more issues, please post on the Joggler Forum because this comment list is getting a little oversized!
