Yes, I managed to brick my landroid. I even got a bit worried before I managed to unbrick it again. And while unbricking it via jtag/swd I made a simple modification to please the programming god!

This is just a proof of concept that I managed to unbrick and flashed my modified firmware via openOCD.

The next step would be to do a REAL 'Hello World', but for this I have to identify the unknown 128x64 chip-on-glass display.

I tried to dismantle but the pieces seams glued stuck and I don't want to break anything. So I'll search around and see if there are any standards how to speak to the display.

It talks via SPI and uses 8 pins.

1. * K
2. * CSB
3. * A0
4. * SCLK
5. * SDA
6. * VDD
7. * GND

I also noticed I missed to identify an IC, probobly an RTC (Real Time Clock) type of chip:

I can't find anything on this, so if anyone has better luck please let me know!
