Once I tried the ayufan 0.7.2 linux kernel from 0.6.2, and I got problem that can not boot after upgrade.
So I installed ayufan's Android 7.1, but I think that is not fit my requirements.
And then I use dcfldd to restore the backup that I made before.
The following was how that made.
sudo dcfldd bs=4M if=/dev/mmcblk0 | gzip > image.img.gz
sudo sync
I restore by this.
gunzip -c image.img.gz | sudo dcfldd bs=4M of=/dev/mmcblk0
sudo sync
And then, eject the sd card and reboot, it works for booting into my ubuntu mate.
And I shutdown the pb, restart again, It will hang after boot.
Sometimes it will bot into desktop, sometimes not.
I restore again and again, always works at first time after restore boot, and then almost hang.
Very strange.
I had installed newest os (q4os) now.
At what point does it hang? Any output on screen and do you have serial output from the UART?
