[Android Q&A, Help & Troubleshooting] Gazz:
I got a cheap Fusion5_108 tab off ebay working but with a cracked "screen"

i've ordered a new digitizer... atm it's totally unresponding to touch, but will work with a mouse / keyboard in the usb A socket on the tab.

So i was playing with it, i plan to use it for one specific task... part of a train driving control desk, the tablets will be the displays found in German trains... i.e. the 'MFA' thats speedo gauges and lights on one tab, electronic timetable on another tablet, the engine dignostic data on another tab, brake pressure gauges on another etc... i already have a lenovo A6700-f that i replaced the digitizer on and did the same things to, and it still works fine.

I loaded the 'TS_MFD' app that works with the train sim via tcp, got it all working fine.

Then i decided i didnt like the google search bar along the top of the home screen, and found out online that by disabeling google services app, it'd get rid of it... so i did that, the search bar went.. but left a shadow box where it used to be... so i thought i'd reboot the tablet and see if that got rid of it.

Held power button in till i got the shutdown / re-boot options, chose re-boot.

Aaaannnd... now it's stuck in a boot loop. all it does it begin to start up... the Fusion5 logo comes up, then it goes "android is starting" 'optimizing apps, 1, 2, 3 of 3...'

Then black screen with android in middle, and that screen goes brighter and dimmer... then eventually it'll reset, and show the "android is starting, optimizing apps' thing over and over.... once it froze on the optimizing apps screen, the circle that goes round froze. but usually it's just loops... left it overnight and still doing it this monring.

If i shut it down by holding power for 10 seconds or so, and hold any volume button and power, it'll start the recovery thing... BUT all i get is the dead android and "No Command'

And no combinations of pressing the power and volume buttons will do anymore... even tried with a mouse and a keyboard... best i could get is a re-boot pressing CTRL - ALT - DELETE on the keyboard.

There seems no way to get this thing to show the recovery options... when i did this on the lenovo tab, it went straight to the 'select option with volume buttons' thing i'm expecting.

Obviousely there's no wany to get this tablet into USB debugging mode, trying the thing where you hold volume button, plug usb cable in, press power 10 times, it sometimes shows up as a usb media devise, sometimes a NDIS internet sharing devise. but they go when it boot loops.

I even tried de-soldering the battery and leaving it for 20 minutes, but upon re-soldering the battery onto the mainboard, it does the same boot loop thing.

I've read i could use Phoenix card writer to make an SD card with the firmware on it, and start the tablet up with that sd card in the slot and it'll load from it.... but where do i find the firmware? the allwinner site doesnt seem to have a firmware... that i can find for the A83T processors.

This is all i know about this devise:

Allwinner

Fusion5_108

1.0

002001014108aa62de01

A83t processor (confirmed by looking inside it)

not mine.. but same model:

ro.product.firmware=v6.0rc4_20161114

ro.fota.version=Fusion5_108_16_OS60_UK_20170310_V2F

ro.inet.model.name=N1061L14BC

Any suggestions?
