Posted in the wrong thread earlier. My unit is still bricked. I'm willing to jtag or try things to recover this unit to working condition again. Took it apart and took pictures. jtag ideas pionara? Hopefully pictures can help determine what we need to jtag this thing...

Bumping this thread. Bricked my unit years ago. Willing to try jtag or any other ideas. Anyone have ideas?

pionara,

Hey, how are you?

I still have my u310bt unit. It's still bricked. I decided to drop by the forum today for fun. And to see if anything has come of this. I am wanting to play around and experiment with the unit if you're interested. I'd be willing to jtag, etc. Let me know if interested in unbricking the device. Thanks!

Does any of this help?

I'll research more on jtag and see if i can come up with anything. The ARM processor is a popular processes used on many devices... I think we can figure something out with this.

Any update pionara for my/our situation? Check your pm btw.

Nand flash would flash to the stored memory of the device directly. Almost like a recovery menu. It may be similar to the unoot thag you are talking about although i have no experience with the uboot method... I would be willing to explore jtag at this point. You certainly know much more than me when it comes to this so if you could give a starting point or some direction, that would be great. I want to try to bring this thing back from the dead.

Question:

Why wont mine boot into test mode? It seems to be stuck in this mode that checks for the update files...

I believe a nand flash method would work. It is stored on the nand partition right?

sorry basket, there is no way to recover from that stage that im aware of... i have tried many things... only way i know of to get a unit in that state is to flash with wrong or corrupt firmware.... it doesnt ahve any uboot menu that i can find so you may be stuck in this mode...

There has to be a way to force the files to the My Flash directory on the unit

epa, I have the backup folders you are looking for. I need to know how to replace the folder on the gps "My Flash" with the backed up ones. I erased my whole "My Flash" folder on my u310bt.

I think I've figured out what my problem is. Because I can't access WinCE/testmode I need to know how to push it back to the "My Flash" folder from my backup...

FYI, these are pictures of the same screens I have:

Okay. I may have bricked mine. It seems to be able to read this sdcard but it goes from the "Updating image" screen to a blue screen with "Open OS CKS File Failure. Please Cold boot and Retry" in red and in the center of the screen... No matter which bin and cks (either the new or my own backup) doesn't change the results. Is there anyway to replace the "My Flash" folder with the backup I have?

No...

Pionara, can you please tell me what files i need to put on the new sdcard? Do i put the folder named "update" or do i put the whole "QI...." folder on the root of the sdcard? Also, i know i should put the cki and bin file on the root too. I will also try formatting the card with windows this time to see if that makes any difference. Please let me know! Thanks!

It wouldnt show a progress bar. After sitting for 30 minutes i decided it wasnt working. Then i pulled the sdcard and reset it. It went into iboot recivery mode and recovered the old/existing software on the unit and booted into it. I didnt upgrade. Then i tried other options which led me to deleting my My Flash folder...

Whats weird is this is the sdcard i used to update the firmware previously. I will still try another card cux you never know...

I only get the full blue screen that states updating. It does nothing. Prior to me deleting the My Flash folder, i could remove the sdcard and it would reset itself to the iboot (?) bluescreen and show a progress bar at the bottom. It would then reset and boot into the old version of the software. The pioneer nav screen. After deleting the My Flash folder it will no longer do this. Gonna grab a different sdcard today.

Thank you for the reply. I have the u310bt model. I put the appropriate files on the root of the sdcard. It seems to not do anything. It just freezes at the blue screen after a reboot. It states "updating image..." or something similar no matter what files i place on the sdcard... I have tried to use the cks and bin files from my original backup as well. It doesnt do anything with those on the sdcard either... I have tried reformatting the card to different filesystems at this point as i am desperate to get my unit in working condition again.

If it was possible to get the updating process to work, im sure that updating this unit would be very easy as the footwork has been done by you guys. Sidenote: i tried all of this with the screen removed from the unit itself. I have had it plugged into a usb charger to keep the battery going. I dont know if that makes a difference but i am trying to give as much info as possible.

Please help!!!! I can provide more information if it is needed!

Or if anyone would like to help i can use email too.

I wasn't able to get the update to work after following the instructions in here or the one's from the other post. I decided to delete the My Flash folder while in testmode and managed to get to the aplupdate program and run it. The unit restarts and shows a blue screen that displays "Updating Image...". The image never changes or updates. I think I have done something permanent to mess up my unit. Please help if anyone can!
