Question [Help] Kindle basic 11th cannot boot

Hi, I got a kindle basic 11th edition that cannot boot (tried press power button for 40s already).
I connected it to UART and get below message:

Code:
F0: 102B 0000
F3: 400C 0000 [0200]
F3: 1006 0033
F3: 4001 00E0
F6: 380C 0000
F1: 5003 FF1E [0001]
F1: 5003 FF1E
00: 1005 0000

BP: A800 0288 [0003]
EC: 0000 0000 [0001]
T0: 0000 00C0 [000F]
System halt!
Does anyone know this error?

It's the basic version, you could easily locate it near the display connector..

Thank for your response.

Could you please share a photo of serial connector or PINs for PW5?
Mine is still on warranty, so I didn't disassemble it yet.

@Hightree:

PW5 doesn't have serial connection pads on production version of PW5's motherboard.
I opened 2 units and unlike on FCC internal images (from https://fccid.io/2AYXP-6252/Internal...ternal-5369878 ) this area marked in read on the photo below doesn't exist:

@shamanNS,
Have you seen any kind of physical reset button inside of PW5?

I don't know much about this button, just seen it mentioned in a very old thread (smth like a button that can trigger a factory reset or automatic installation of FW?).

There isn't anything like that. PW5 is a totally locked down black-box. When you end up bricking it your only course of action would be finding someone that can remove the eMMC > write data to it > reattach the eMMC chip.

And you shouldn't be trying to test on a PW5 device all those ideas you've been inquiring about here on various topics. Buy a used PW3, setup Coward's Rescue Pack and then go nuts with testing and perfecting your software mod ideas.

And if you haven't already read this:

Thank you, very interesting link.
Why PW3?
Is there diag partition?
Backlight?
How much RAM?
