PW3 Unbrick a PW3

OoMG · 07-04-2018, 08:48 AM

Hi, my PW3 wasn't able to start.
I tried to rescue it by using TTL, but it can't boot into recovery menu.
it shows "can't get kernel image".
Is there anyone could help me?

Thanks very much.

Do what it is telling you it requires, install a "diags" system kernel image.

PS: do not wait until you see:

Code:

Hit any key to stop autoboot:  0

Instead, as soon as you see output on the serial port line, press AND HOLD the "any key" down until u-boot sees it.

Thanks!

Where can I download the "diags" system kernel image?
This link is the right version for pw3? https://ixtab.tk/kindle-touch-images..._kernel.img.gz

I found instructions from https://gist.github.com/TobiasWooldr...ca75190b9a473f

No, it is for the PW1 not the PW2 or PW3

On this forum's index page, there are a number of threads in the "sticky" section.
One includes: "Where do I start" in its title.
Go there (first post) and dig a bit for the proper de-bricking instructions.
Otherwise:
If you use Tobias Wooldridge's instructions, get him to help you.

I had the same problem.
I recovered pw3 with this article.
https://www.mobileread.com/forums/sh...d.php?t=269099

However, I removed the diagnostic partition and kernel during the repair process,
I could not recover it.

Can anyone provide me with diagnostic partitions and kernels?
If so, please send it to my email address.
hana121024@yahoo.com

or,
Is there a way to log in to the Kindle system without using the Exit to login prompt in the Diags menu?

knc1 · 07-06-2018, 01:12 PM

I have posted here a backup file that creates the required files.
All you need is the 'diags' kernel and 'diags' filesystem (because Amazon posts an image with all of the 'main' files in it).

hanalee · 07-06-2018, 09:36 PM

I knew I had to backup but it was too late.
My partition and kernel were removed.

Knc1's excellent advice was to restore the main partition and kernel,
I could not recover the diagnostic partition and the kernel.

I did a search to repair the diagnostic partition and kernel, but I found only backups.
