I have a Hannspree TV box with RK3288 (Android mini PC) on which I would like to install Armbian according to instructions from this forum (Multitool).
Multitool booted
Backup of the original firmware
Flash written with Armbian.
Reboot (did not happen, box does not respond)
Power off and power on.
Monitor stays black, monitor goes into standby
Just now I have to note that there would have been a more appropriate thread (without Q8), so I fucked up from the start.
I tried to recover the box with the original firmware I had backed up with the multitool using a USB-A to USB-A cable. But this image was not recognized.
I tried to install the Rikomagic firmware (MK902II seems to be identical in construction), but it kept aborting at 99% (download firmware fail).
I tried several times, but after some time the recovery tool under Windows (*sic*), did not recognize the box.
Also under Ubuntu, the box no longer appears under lsusb.
I made a connection via UART. The first error message is:
GPT 0x3337df8 signature is wrong
recovery gpt...
GPT 0x3337df8 signature is wrong
recovery gpt fail!
UBoot still seems to work?
CPU: rk3288
cpu version = 0

or not?

Sorry, this is rather new territory for me.
Anyway, the boot process ends with:
[ 19.162284] init: Starting service 'clear-bcb'...
[ 19.173024] fs_mgr: Warning: unknown flag resize

[ 20.165006] init: Service 'clear-bcb' (pid 1802) exited with status 0
Nevertheless a Linux starts:
cat /proc/version
Linux version 4.4.143 (work2@czkj) (gcc version 4.9 20150123 (prerelease) (GCC) ) #23 SMP PREEMPT Fri Jul 5 16:35:06 CST 2019
But there is no signal output via HDMI.
How should I proceed to bring the box back to life? Does anyone have a link to a manual that could help me?
Thanks in advance
