Hi Renate. I got your message and custom rec
I flash the custom recovery to both rec a and b, after that reboot to recovery
Code:
edl /u /w /precovery_a rec.img
edl /u /w /precovery_b rec.img
edl /z
adb reboot recovery
The screen show blank on reboot.
Code:
adb shell
#id
.....
#start autoupdate
The text is right up, waiting for drive. It's all done now.
I format the data to make sure everything ok. It can be updated through ota to the latest 4.0.2 of Air3.
Im testing the device now to see if there's any incompatibility
