PW2 Help debricking PW2

[sz.bali]

Hi,

I have a Paperwhite 2 that shows the kindle logo on the screen and doesn't respond to turning on/off or hard reset.

I opened up the kindle and connected to the serial port and this is the output I get:

I've managed to get recovery menu, but I don't know which option to choose, or even if one of the option would fix the kindle (or at least safe to try without destroying the system even more). These are the menu options:

Menu
====
3. Load MMC over USB storage
4. Erase MMC
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
C. Configure USB networking
N. Boot NFS over USB
Z. Boot NFS over ETH
L. List files in many directories
S. Access the shell
8. Test low level screens
D. dmesg / kernel printk ring buffer.
Q. quit

Can somebody make sense of the output and have an idea what could be the problem and how to fix it?

I'm no expert in this, but seeing that I/O error on the MMC device may indicate that the storage chip itself is dead/bad. If this is indeed the case you have a spare screen unless you have a workstation available to replace the MMC itself.

I will defer to others with more experience in this area, as it might be possible to recover from this. Although it might have reduced capacity available even after recovery is complete.

Where you captured this:

[   22.610798] mmc0: Timeout, intmask=0x00010000 
[   22.615157] mmc0: Trigger MMC Recovery 
[   22.618985] mmcreinit_work_func: Resetting MMC, try=1, total_time=0 
[   22.694722] mmc_reinit: Reinit card

Let it run, at least over night, to see if it can do the recovery.
You can't wear it out any worse than it probably already is.
Keep the USB cable plugged while it runs, you don't want it to run on the battery like that, not for over night.

The problem is it stops the recovery after 5 tries:

And after this there's no other output, so I think it won't change anything if I run it overnight. Or maybe there's a way to let the recovery run past 5 tries? Or anything else to try?

You are correct.
I somehow missed those lines.

As mentioned above in another post here, you now have a used screen for sale.

Can't OP replace the eMMC instead? I remember that you once said (https://www.mobileread.com/forums/sh...d.php?t=271750) that it costs under $10.
But one must keep in mind that the eMMC is not trivial to replace (chip rework station, reworking skills, ...)

There is a thread here for the purpose.
Not a trivial fix.


Not for a device that the user has failed to create the required backup files (I have posted a script for that purpose here.)
I.E: Some of the user and device information lives OUTSIDE of the file system. My posted script will backup that information also. And you will be unable to use the new device if you do not have that information available.
