Jolla C is now a brick
 

After about a week of testing and setting up my new Jolla C I had to repartition my SD-Card that had one partition f2fs and one SWAP to ext4 and swap. I did so using parted from openrepos and creating a new partition table on said card. The card mounted fine on Jolla C as did the SWAP partition. After a while I decided to reboot the phone and since then it has not turned back on. No vibration, nothing.

I fear that somehow the NAND could be affected by partition table writing? Is there a way to connect NAND to a PC and check if everything is okay, or do I have to send in the device?

Connecting the Phone to PC shows QHSUSB__BULK in device manager - maybe this is a starting point towards flashing the device or repairing something.

Overview:

1: Tinker with partition tables on sdcard presumably - as that did work - mounted fine as swap and ext4
2: attempt reboot
3: stay dead
4: take out SIM and sdcard
5: attempt boot - stay dead
6: attempt recovery (vol-up + power) / fastboot (vol-down + USB) - stay dead
7: connect to PC - QHSUSB__BULK in device manager
8: open ticket at ZENDESK

Has anyone got a clue? :D

[EDIT]

9: get help from the inner circle
10: be educated QHSUSB__BULK mode basically exports the emmc via USB

[EDIT] (QHSUSB__BULK will either say Qualcomm 9008 (service port) or Qualcomm 9006 (emmc mode) the one we need)

11: expected behaviour on linux: show emmc partitions and list device on /dev/whatever
12: actual behaviour lsusb lists device as connected to one USB bus but does not list as any device to the system
13: conclusion - send in the device - as even with the by now provided original partition table, there seems to be no way to write them back to my Jolla C
14: sob and tremble uncontrollably
15: buy iPhone - jk

You may keep the pieces :cool:

Re: Jolla C is now a brick
 

I will decorate my trophy collection with this new brick! But I'd much prefer to let it age well before that ;)

Re: Jolla C is now a brick
 

No worries. As far as I know you didn't bought a phone but part of a program.

Hou...tricky one...
Send it to jolla and tell them to fix it since it broke on first start up ;) and request a new...

Re: Jolla C is now a brick
 

Just for the record, you did not mention trying to get into recovery menu.
You sure tried and it did not work, correct?

Re: Jolla C is now a brick
 

I had opened a ticket earlier and will await their answer.

Hope they can help me out.

I did try recovery and fastboot (voldown + usb)

Nothing works, the device stays black. Only thing is upon connecting to USB said device pops up in device manager indicating something is severely wrong.

Re: Jolla C is now a brick
 

Good to read you take it like a man :)

Re: Jolla C is now a brick
 

Me taking it this way is nothing compared to the poor folks longing for one and seeing me waste mine just like this.

Don't behead me!

Re: Jolla C is now a brick
 

At least you documented what not to do.
Can be helpfull indeed.

Re: Jolla C is now a brick
 

You did not mention if you tried rebooting without the offending SD card.

Re: Jolla C is now a brick
 

The correct key combo for recovery mode is Vol UP + power key. Please try that ;)

Also good idea to remove any sd card from the device if you have such there. Unfortunate partition label could cause an issue..

Re: Jolla C is now a brick
 

I've updated my first post with hopefully enough info as to what I've tried and what does not do the trick ;) Thanks for reminding me!

Re: Jolla C is now a brick
 

Sadly, what most likely happened, is a deleted/faulty SBL partition, this is the Qualcomm bootloader damaged, and only repairable by Qualcomm tools. The device boots to this mode when normal bootloader partition is damaged, thus the device can't boot.
So far none has figured out how to repair this, outside factory (except on XDA forum, for a few devices).
This happened for at least one user here, on J1 (search my answers)

Re: Jolla C is now a brick
 

Well if that really is the case - and by all means a quick google search pushed me into the XDA case too - then Qualcomm thus Jolla should have documentation on it, should they not? Maybe they can share what is needed - or tell us why we can't have it.

Thank you for this insight. I will wait for an official response from Jolla before any further tampering with my Jolla C in its current state.

Regards!

Hero.......
Aquafish is your way to go

Re: Jolla C is now a brick
 

MoritzJT, seems obvious, but have you let the battery to rest properly? In the early days of J1, I issued a halt from command line, and the phone was a brick. But battery out for 15 minutes and back in and then it started. But as I said, you probably have tried this already.

Re: Jolla C is now a brick
 

Thank's for the heads up, sadly that's also one of the things I had tried.

The ticket I opened with Jolla Care was closed and I have been redirected to developer-care@jolla.com - forwarding them my issue. They are yet to answer me.

I hope I'm not screwed here. Back in my Symbian days, bricking a device was nearly impossible - even dead flashing and correcting the partitions layout was easily possible, because we had all the tools necessary. With Jolla, Qualcomm and what not - this is an extremely sad situation. Dependency on the big manufacturers and THEIR rules makes me angry.

Re: Jolla C is now a brick
 

A little update - Jolla C does not come with any warranty according to Jolla. I'll have to pay for transport AND reparing. I'm waiting for Jolla to tell me how much it will cost to repair my device and decide whether to send it in.

Re: Jolla C is now a brick
 

Possibly if you can wait to the next Jolla event you might find some sailor willing to reflash it for you...

Re: Jolla C is now a brick
 

What kind of Jolla event would that be? I've never been to one. Do sailors themselves have access to the factory images?

Re: Jolla C is now a brick
 

If you connect usb while holding voldown, fastboot will be availavle?

Re: Jolla C is now a brick
 

lsusb still lists a qualcomm device, it will however not list as a block device - the last thing I hoped for.

There is no more fastboot.

Re: Jolla C is now a brick
 

No, the only way to safe this device is using Qualcomm tools. Ian not sure if even Jolla got those (they are licensed $$$)
Read my answers to this special bootloader mode in other threads.
While the mentioned tool can be found, pirated, we still need certain files and XML partition layout for this.

It's not undoable, but we don't have all the pieces of the puzzle.

Re: Jolla C is now a brick
 

I suspect any event where Jolla sends one or more hackers. Only FOSDEM comes to mind right now, but I hope there's some earlier developer/community event before that (like the JollaC one).

Obviously, at least some sailors have access to factory images and flashing tools.

Re: Jolla C is now a brick
 

Interesting , do you know who?

For others, like I said, the SBL(1) is erased/damaged and thus the phone don't know how to boot. Leaving it in this factory mode. Unable to enter fast boot, recovery, or, normal boot.

There is good reference, also how this can be fixed on certain Android devices.

If we can create similar for Jolla phones, yes, it is recoverable , but until then, probably only the factory can recover this.

Re: Jolla C is now a brick
 

I will make a case against being able to modify SBL or partition tables from the phone in general just by being root. There should be one more layer of protection.

I have been through many of the XDA resources along with some android unbrick blogs - they all rely on the provided images. I have yet to see a 'reverse engineered' effort succeed reviving a phone with some frankenstein image.

Citation from a comment I received on the following resource by androidbrick: http://www.androidbrick.com/ultimate...oad_qpst_qfil/

"Thank you so much for the kind words. As to your problem : Qualcomm 9008 port is simply just a “service port” that waits right files from you to wake up the device. Just a commication port, you cant manualy flash anything over it. You need a proper service rom that includes ““rawprogram0.xml”, “patch0.xml”, “prog_emmc_firehose_XXXX.mbn” or “MPRGXXXX.mbn”” in it, without those files your phone cant come back sorry. Those mbn files are a must to turn your bricked phone into EMMC mode again (Qualcomm 9006), so your phone’s EMMC drive will wake and accepts your backed up partititons again from linux or from an other windows based partition software.. So you just need to find those, or nothing can be done, sorry. Greetings."

So for now that means we (I) need to switch from Qualcomm 9008 (service port) to Qualcomm 9006 (emmc mode) requiring:

- rawprogram0.xml
- patch0.xml
- MPRGXXXX.mbn (as at least Jolla C listens to Sahara protocoll, not the supposedly newer Firehose protocol)

And I don't even think that the .mbn file is the actual whole ROM, in our case SFOS but just the part needed to revive the device. Does it include anything that falls under NDA? Who can tell.

That's our situation, judging from the dead Jolla 1 thread.

Re: Jolla C is now a brick
 

The mbm files can indeed contain full rom.
But to recover only the SBL is needed.
The xml files can proberly be reconstrocted, proberly also the mbm files, but not without a great deal of effort.

So, yes, as I said, at the moment most likely only the factory have all the pieces to this.

Re: Jolla C is now a brick
 

Being able to do it only as root is the protection, so I am against any "uber-root" hurdles you're proposing.

<rant>
The problem is that people (especially Android users, but many people on TMO as well) don't realize what it means to do stuff as root. With the power comes a great responsibility and regular users should never play with root access.

Yet there's a lot of "yo yo, I just rooted my phone, just because I can" attitude.

Just look at the "SailfishOS pre-pre-release" threads where good amount of users goes through an unnecessary risk and then is surprised when something breaks. There were plans by Jolla last summer to introduce upgrades that would overwrite the system partition so you don't have to hop over updates every time after resetting your phone, but imagine what disaster it would be if they tried to do it and bunch of users went ahead with their

routine prematurely...
</rant>

There should be no "just by being root".

Re: Jolla C is now a brick
 

Well, rainisto and Stskeeps both mentioned at some point having it.
However, to the best of my knowledge, both have left the company. :/

Re: Jolla C is now a brick
 

I stand corrected and have underestimated a well know effect.

http://www.goethezeitportal.de/filea...erlehrling.jpg

Do you suggest to not even create dedicated posts here on TMO for those topics or how should this be handled ethically correct?

Re: Jolla C is now a brick
 

Most, or many, posts comes with a big warning.

But, perhaps, making a pinned post stating the dangers of God mode ?

Re: Jolla C is now a brick
 

Can we save the SBL from live phone for backup?

Re: Jolla C is now a brick
 

A good idea to do so, helpful I believe once its figured out how to extract the needed files.

The partitions of J1 is like this, not sure of C.

Re: Jolla C is now a brick
 

Interresting - so, the C have backups of the critical partitions.

Re: Jolla C is now a brick
 

What are they good for if you delete their table too :eek:

Re: Jolla C is now a brick
 

Teaching people who shouldn't be messing around, the hard way.

Re: Jolla C is now a brick
 

No that's the task of what follows if you mess with them ;)

However - what are the backup partitions good for, can the primary ones get corrupted? Is it used for some ongoing check against?

Re: Jolla C is now a brick
 

It's probably the recovery method since we know it will be different to that on the JPhone due to lack of Btrfs.

That doesn't help you, but as you found out if you aren't super careful when running fdisk as root you can break things :P
