Kindle 7th gen bricked

[herpez]

Hello. I have a kindle 7th gen WP63GW and one day the battery went 0% and is now dead. I tried all kind of things to revive then and nothing.
So i opnened and in battery i have 4.1V so I don't think it is "only" battery related.

Tried to use the serial port and all the time i have this error:

[ 58.243573] mmc0: Timeout, intmask=0x00100000
[ 58.248967] mmcblk0: r/w command failed, status = 0x80900
[ 58.254983] end_request: I/O error, dev mmcblk0, sector 1118259

[ 63.692958] mmcblk0: error -110 transferring data, sector 1118256, nr 8, cmd response 0x900, card status 0x80b00

So, any help here please

Do you get the same MMC errors when booting into diags?

I admit i am a bit lost here. I couldn't find how to boot into diagn mode but i was able to see these options on boot.
Does this help?

I. Initialize Partition Table (fdisk) and format FAT
O. Format and overwrite FAT partition
E. Export FAT partition
U. Update using update*.bin file on FAT partition
D. dmesg / kernel printk ring buffer.
Q. quitLo

[herpez]

So, i booted into diagnostics and this is the log

And the output of the diagn is this:

Try to select the option E. Export FAT partition, connect your Kindle to your computer via usb, create empty files on it called DO_FACTORY_RESTORE. Restart the reader.
If during formatting again there are errors reading mmc, unfortunately it will mean a damaged flash memory.

I will do it next time I get my hands on the kindle and will report the feedback as soon as i do it.
Thanks

I did as you said, mounted the kindle, created a file named DO_FACTORY_RESTORE without any extension. Rebooted and still the same.

Any other option avaiable like flash a new system or i can assume the mmc is dead?

[herpez]

I guess its the emmc end, right?

[herpez]

Btw, i can also go to fastboot mode, but don't know if it is useful...

[eddie.t.h]

Definitely, the flash memory needs to be replaced. This is not a simple repair, it requires bga soldering skills.

Thanks. Going to sell / offer for parts.
