Hi
Bought a box of "defective" Kindles out of a whim... now I have 5 PW3s. I opened 4 of them, so I have the possibility to connect the serial console. (Working on a Debian system, with working fastboot connection, got that hurdle...)
No1 had a dead battery... replacing it brought it back to life but I suspect the charging circuit might be broken, have to test that.
No2 is starting up but then just showing the screensaver (no touch or anything). On the serial console I see U-boot starting up
Code:
...
Welcome to Kindle
...
info asr_setup:Not in asr mode::reason=flag file not present. shutting down asr_setup::
info hardware:no_wan::WiFi only device. No WAN found
info board_data_file :/opt/ar6k/target/AR6003/hw2.1.1/bin/AR6003_wfo_calfile.bin::

[ 400.888536] pmic_soda_connects_notify_otg_out:423
and that's it... if I connect it to a Win PC I see a drive detected, but I cannot access it.
Any Ideas on what might be wrong and how to fix it? I've read about DO_FACTORY_RESET file but I cannot access the drive...
No3 shows the same behavior as No2.
No4 displays a page of a book but does nothing more, no reaction to reset via power button (>20sec).
No5 has a whole in the screen and a bent motherboard... so no help there, but the batter was still alive.
Then I've a WP63GW with a strange looking image on the screen, serial console shows
Code:
[ 1.741247] max77696-epd max77696-epd.0: EPDINT: Regulator Fault Detected [12]
[ 1.748534] Regulator Fault Occurred! Retrying powerup...
Guess this on is fatal as well...
And I've a SY69JL with a kindle Power On picture and a D01100 with a drained battery on the screen, which I did not yet open up.
Would be thankful for some tips/hints, I'm fairly new to this kindle stuff
