K5 Kindle Touch still bricked even after using Kubrick

[derivativeoflog7]

I got a bricked Kindle Touch, showing the "Your Kindle needs repair" screen
When I got it, when I plugged it in my computer, it would reboot (again to the error screen), but it would show as a drive for about a minute
I found about Kubrick, so I got an old PC and ran it, checking the Install jailbreak option and both erase/format options (since I wanted to wipe it anyway)
Once it was done, it rebooted to the language select screen, then it rebooted a few times with a flashing loading bar and the startup message... and now it's back to the same error screen. However, now it won't even show up properly on the computer, it shows as an empty drive!

What could I try now? Any diagnostics I should run?

Maybe the storage is dead for good?

Sounds likely. Guess the only way to be sure would be to open it up and get serial access while booting to see what errors are reported.

Thanks guys, I'll see what I can do to attach to the serial port... that connector seems irritating to use tho. Honestly it would've been easier if it just had bare pads for the serial like most other devices!

After a McGyvered serial connection setup I managed to get the boot log
The error screen appears after

info shutdown_showimage:screen:waiting for cust_service screen to come up:

Another issue now is that I only had a 3.3V adapter so I only connected to the Kindle's Tx for safety
Here's the log:

Hmm. Someone more experienced than I in reading this log will need to confirm this, but this line stands out to me:

info userstore:found_shutdown_flag::Found SHUTDOWN flag file

This appears immediately before it starts to shut things down. If this indeed is the problem, you will need to invoke the recovery menu, open a terminal window and remove this file.

I saw that too, but how would've it survived two tries with Kubrick?

This stands out to me too:

info X:makexconfig:Accelerometer device: N/A !!:

The thing is, while I was in diags following Kubrick for the second time, I ran the diagnostics out of curiosity, and the accelerometer was working

Also, as for the serial adapter, I ordered one that also supports 1.8V from AliExpress, let's hope it arrives soon

[derivativeoflog7]

Maybe someone with a working KT can post their boot log for comparison? Or there's one available somewhere

[derivativeoflog7]

I finally got the adapter, but I'm extremely busy this week and I won't have time for this Kindle... if anyone has some ideas about what I should try when I can, let me know!

[derivativeoflog7]

Well okay, curiosity got the best of me
I can interrupt the booting process in two stages

First one is when it says Hit any key to stop autoboot:, I get the following menu

uboot > help
?       - alias for 'help'
bist    - start Built In Self Test
boot    - boot default, i.e., run 'bootcmd'
bootd   - boot default, i.e., run 'bootcmd'
bootm   - boot application image from memory
go      - start application at address 'addr'
help    - print online help
idme    - idme    - Set nv ram variables


log     - manipulate logbuffer
printenv- print environment variables
reset   - Perform RESET of the CPU
run     - run commands in an environment variable
setenv  - set environment variables
version - print monitor version

One thing I notice is that, if I run idme, i get this:

serial: B0111408210505H1
accel:
mac: 28EF01689168
sec: EJ7OF378VSQVG3KJC4B2
pcbsn: 0061405114850Q5W
bootmode: main
postmode: normal

I'm VERY sketched out by that accel: <empty> because, as I said before, running a diagnostics from the recovery mode using Kubrick seems to confirm it does actually work! Maybe writing a variable there will fix the issue? I have no idea what to set it to though... maybe if someone gives me a known value I can try that

The second one is when it says Press [ENTER] for recovery menu..., and I get this:

Menu
====
3. Load MMC0 over USB storage
4. Erase MMC0
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
M. Update using update*.bin file on FAT partition of second MMC port
D. dmesg / kernel printk ring buffer.
Q. quit

But nothing here seems to be useful in my case

I don't know how to navigate in the recovery menu to delete this file, could you help me?

[amocus]

What I did for Paperwhite:

Download latest firmware from Amazon, rename it to update.bin.
While in serial in Recovery Menu, select
E. Export FAT partition

next attach USB to your PC, load update.bin into main directory, safely disconnect kindle from PC, in console select
1. done

back in recovery menu select
U. Update using update*.bin file on FAT partition

it should restart and load latest firmware. I found this metod the fastest - not searching SHUTDOWN flag file

Ok so, this is really weird
I wanted to try this, so I dug out the Kindle and got Kubrick again to get it into diags
I copied the update file, but then couldn't find an update option in the K5's diags
Nevertheless, I had Kubrick reflash the firmware again, then I skipped all the optional stuff (jailbreak, reformat, etc)
Kubrick then rebooted the Kindle, and it went to an update screen, but it errored out with UPDATE ERROR 3
And then it rebooted again, and I was fully expecting it to just immediately go to the error "your Kindle needs repair" screen again... except... it didn't, it booted and is now working perfectly fine
So... I guess problem solved? Still have no idea why it didn't work 10 months ago
