Hello everyone!

I have a Kindle Paperwhite 2021 (11th Gen, model M2L3EK) that is stuck on the boot screen. It will not load the home screen, and it is not recognized by a computer.

I have already tried the standard hard reset (holding the power button for over a minute), as well as a full power cycle by unplugging and reconnecting the battery. I measured battery with multymeter and the voltage was good.

Unfortunately, I live in Serbia where there is no Amazon representation, and the device is out of warranty...

I am now looking to attempt a debricking via a serial port. I was hoping someone could provide any info , a photo, or a description of the location of the serial port pins (TX, RX, and GND) on the M2L3EK motherboard.

Yes, this is what it look like oppened↓
