@some0ne I can't tell you why multitool does not find the eMMC anymore, could be several causes, but without the multitool log it is difficult.
 
A note about maskrom mode emmc clock pin, in case you are using or used that in the past: when the emmc clock pin is gated, emmc is de facto turned off.
 
If you are able to get in maskrom mode, then you can erase manually the eMCP connecting the board via male-to-male USB cable and using rkdeveloptool:
 
./rkdeveloptool db rk322x_loader_v1.10.238_256.bin Downloading bootloader succeeded. ./rkdeveloptool ef  
The loader file and other instructions are on first page.
 
However, at the moment I don't understand what you have on your eMCP, if Android boots, or is already empty or what?
Lastly, I don't know where your 60 seconds issue comes from. You should first clean the eMCP from anything on it and then boot pristine armbian from sdcard, then we may talk about that.
