Back to thread topic.
What I am thinking, is that it might be possible to switch USB modes, so that the device will expose its NAND thru USB, and allow us to mount it in linux.
Then, following that, we could restore the device partitions, from a copy of a working device. Or, in Jolla C, perhaps from thoise backup partitions.
I didnt test, but perhaps Jolla exposes more modes in this condition. Like it was found for Samnsung devices, which exposed 2 modes, allowing to access the modem, make calls, etc.
https://github.com/ud2/advisories/tr...ocve-2016-0004
Tells how this was done on Samsung devices.
And
https://github.com/ud2/advisories/bl.../usbswitcher.c
Have a exploit that might be modifiable to work (if more modes avail).

It must be possible to switch between modes. However the Qualcomm Tools didn't make it obvious on how to do so. Judging from the advice from androidunbrick as stated in my post here: https://talk.maemo.org/showpost.php?...2&postcount=26
it's necessarry to have the flashable files to get it to fire up EMMC exposure mode again - and without those files it wouldn't be possible. I don't think however, that the mode that exposes EMMC somehow relies on working partition tables or any files from NAND. It would make much more sense if the exposure itself would remain independent and there actually IS a way to achieve what you're suggesting.
I guess without someone with deep technical knowledge in the field, we're a bit stranded :-(

Well I would also be extremely careful if my device wasn't bricked. Maybe we succeed switching modes once, but not back to normal. So far I see why you'd need one. I could send mine over if you're keen on experimenting, but I don't see why you'd do it - you get nothing out of it - there's nothing I can offer.
Currently I'm waiting for Jollas reply to my flashing images rant I attached to my support request. James has been relaying that info to the team and is awaiting a proper response. Afterwards I'll see what to do next.
Meanwhile I'll try to tinker with Qualcomm tools again.

Here's a good topic on qualcomm diag modes and restore, although you need to know russian.

I had come across that forum, however I know no russian and google translate does a miserable job at tech talk But maybe someone can scan these pages? Thank you for the link!
