Hi, I've messed up and my kindle is in a bootloop. I'm trying to enter the serial console now but I have kind of a ghetto setup.

I have a chinese arduino uno in "TTL" mode.
RES -> GND
RX -> 2nd PIN (from 1(left))
TX -> 3rd PIN
Schematica from https://www.mobileread.com/forums/sh...55&postcount=1

My screen doesn't output anything over 115200 baud rate. When I run screen without the baud rate and remove the RES->GND short it then proceeds to dump ascii table onto my screen. There's also a button on the uno to re-dump the table when RES->GND isn't active.

1. Is the baud rate and connection scheme correct for B005 DX?
2. Is my screen /dev/ttyUSB0 115200 command correct?
