nexHT IPC360 clone thingy - Ingenic T21N

[Nico1320]

I've gained root access and dumped everything via CH341a. During the boot process, UART no longer works. I've had to enable telnet in /etc/init.d/rcS by uncommenting. Pretty much followed #1741 since it was similar enough.

CH341a dump

What are the next procedures? From what I can understand, I have to test if it can boot via sd card. Do I have to flash the bootloader etc?
