I've a Lenovo Tab A8-50 which received yesterday an OTA update.
After the update it didn't restarted correctly.
It now only show the "no command" screen. When I click the power button it shows this additionnal information
Android system recovery <3e>
A5500F_A442_000_027_141207_ROW
followed by a list of recovery options
- Apply update from ADB
- Apply update from sdcard
- Apply update from cache
- wipe data/factory reset
- wipe cache partition
- backup user data
- restore user data
The problem is I never tried to connect that tablet to my computer using any kind of debug mode, only using standard USB mass storage driver.
I have one microSD card I can use, but it seems this mode doesn't allow me to push firmware from the microSD card to the Android machine.
So ... the question is simple : how can I restore/reinstall a working version of Android on that tablet ?
One additionnaly point is that, as far as I understand, Lenovo doesn't provide any link to the full firmware for that tablet on their support site. So where can i get a working version of firmware, and how can i reinstall it ?
