for more on the btrfs and how it perhaps can help

https://together.jolla.com/question/...ious-problems/

@nieldk at first page i already posred result of [btrfs check --repair /dev/mmcblk-p28] output: http://paste.ubuntu.com/8333525/
btrfs recover failed too

then you will need either
1 that dd copy (i will see)
or
2 send to Jolla

so it means there are no btrfs tool to recreate empty partition? o_O

ok, talking about restoring dd backup back to device. the only option os using ext4/btrfs formatted sd card?

story ends. author successfully received dd backup and restored it.

Hi!

Do you have the backup of the mmcblk0p28 left?
If you have, are you willing to send it to me?

Hey guys, new here but in dire need of help. I got the corrupted app registry error and trying to save the phone I tried to create a bootable SD with sailfish .19 and pretty much destroyed my phone. It seems my problem is akin to what you guys just managed to fix. When in telnet and in shell I get:

# btrfs check --repair /dev/mmcblk0p28
# enabling repair mode
# No valid Btrfs found on /dev/mmcblk0p28
# Couldn't open file system

So can you guys help me with a factory img and the instructions on how to restore it... Thanks in advance.

Thanks, a bit more help as following those instructions is that I basically toasted my jolla...

2) Unpack jolla-sailfish-1.0.8.21.tar.xz and put jolla-sailfish-1.0.8.21.img to sdcard

unpack the tar.bz2 file... so I unpack it to the ext4 formatted SD, but what exactly is the second part? Should I label the SD jolla-sailfish-1.0.8.21.img should I unpack it to that named folder in the SD or should I convert the tar to an .img under that name?

I know it's very basic stuff, but having a toasted jolla in less than a month has me down... thanks to that "critical app registry" error and not knowing on my behalf how to follow instructions.

Thanks in advance once again
