I tried to flash the recovery on top of 1.100.36 (yes, it's really 36, it's an ota update for 35).
So I went to fastboot and flashed the recovery 1.0.1, everything seems to be fine
fastboot: processing commands
fastboot: download:00437000
fastboot: flash:recovery
writing 4419584 bytes to 'recovery'
partition 'recovery' updated
then I reboot my phone as usual, then I boot into recovery (adb or quick boot) and I just see the triangle of the normal recovery.
So I did the following:
adb reboot bootloader
fastboot -i 0x0502 boot recoo.img
I created a nandroid of my normal phone and then i flashed a rom, in this case MiUI 1.4.15.
Once booted I returned to bootloader mode and flashed the recovery again
fastboot: processing commands
fastboot: download:00437000
fastboot: flash:recovery
writing 4419584 bytes to 'recovery'
partition 'recovery' updated
Then in MiUI i rebooted via ADB to recovery, everything's ok recovery is flashed on top of the original.
Then I restored my nandroid of original acer 1.100.36 bin (you have to rename the folder "console=null" to your IMEI, that's what I did) and what happened? My Custom-Recovery
past away
Be careful when yoo flash a bin from Acer or an Update, it can happen that your recovery pasts away and you're not able to flash a new one, except you boot into the recovery, flash a rom and then flash recovery and use the rom
--------
Solution:
Delete/Rename "/system/recovery-from-boot.p", that's a backup of the original recovery. When you need the original back, just rename it back to the original filename and reboot
