Thanks for the pointer! It now shows a lot more information (while the sad Android with red exclamation mark is in the background)
I can scroll down/up using volume button for these options:
- reboot system now
- apply update from external storage
- wipe data/factory reset
- wipe cache partition
- apply update from cache
At the bottom of the screen, it is showing a whole bunch of yellow text:
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
(repeat the above message for /cache/recovery/log, /cache/recovery/last_log, /cache/recovery/last_install
How can i select an option from this menu, btw?
I also tried to use the vol - button. I found that if i keep flipping orientation lock back and forth, it will show 2 messages at the top left corner showing "Erasing Userdata...Erasing cache..." in the Acer splash screen. Then it will freeze again....
