Hello everyone, I'm a newbie here so I am sorry if I posted in the wrong forum.
I've been struggling for days now and didn't get the best way to do it. I have around 140 Tablets that should be programmed and configured the same for a School. I searched for best ways to make a full backup of the one device and restore them to other with no luck yet.
First the Tablet is Chinese
Name & Model: Eken E902
Build Number: astar_m900-eng 4.4.2 KVT49L 20160322 test-keys
Kernel Version: 3.4.39
Firmware is exdroid4.4.2_r2-a33-v2.1
O/S version is Kitkat 4.4..2
I tried adb backup however it only creates a 1KB file "adb backup -all -f C:\filenameichoose.ab"
When I boot into recovery mode all I see it
- reboot system now
- apply update from ADB
- wipe data/factory reset
- wipe cache partition
- apply update from internal storage
- apply update from external storage
- apply update from cache
Fastloader is locked and couldn't find a way to unlock it. I installed Kingroot App (kingroo dot net) to root the device. Then installed Titanium Backup Pro to create a backup. However when restoring I didn't get the result I was looking for some Apps are missing there app data and other apps seach as Google Play Service where not updated. Plus some apps where moved to SD as installation also this wasn't configured, also i didn't backup the system files as I was able to change only the boot logo and not the initlogo or animation also this wasn't backed up and restored. That means Titanium Backup pro will help you half the way it should be.
I tried Helium backup didn't work. I installed so many PC softwares also with no luck to get the thing i'm looking for. So I thought of creating my own rom based on one tablet and flash it on the other tablets however this is risky and we might lose the tablets.
So please advice me of the best way and best tools for my request, thank you in advanced.
