Acer Iconia A1-810

HI guys, I have a problem, I have tried to root from scratch my Acer Iconia A1-810, using my Virtual machine Ubuntu 16.04 32 bit, and all seemed to complete fine, but now I have loop boot. What can I do?

When I enter in the recovery mode, my tablet show me the version: Acer_AV0K0_A1-810_1.055.00_WW_GEN1

PS: I have saved system.img produced by the script.

Here is the log of my operation:

Do you want to do everything all at once (= do not wait for input before restoring system.img?

Make sure to:
1. Plugin both computer and device into power
2. Do not touch the device
3. Do not EVER disconnect the USB of the device
4. Make sure to wait till everything succeeds!

Failure to do so may cause disconnect in the restore procedure which can brick the device!
