Прошивка планшета на AllWinner A23
Hello! My name is Ludger and I'm from germany. I have a old tablet
Brand: MP-MAN
Model MPQC12
Processor: Allwinner A23
Architecture: 4xARM Cortex-A7 @ 1,50 Ghz
GPU-Renderer: Mali-400 MP
Board: exdroid
Hardware: sun8i
Android: 4.4.2
I have Root-access with Kingo-Root and can reboot to the buildin recovery. The version is exdroid4.4.2_r2-a33-v2.1
I want to install TWRP for creating a backup and after this I wand to flash another ROM with a "modern" version such like Lineage or Bliss.
My question is: can I flash the TWRP directly with Phoenix-suite and which version aof TWRP shall I use?
Can I make a backup before flashing TWRP?
Regards Ludger

here I am again. I've tried the howto from the first page Как сделать бекап разделов AllWinner A23 через ADB (скачать можно здесь)
I installed SDK platform-tools and start cmd as admin
First I checked wether the device is connected
then I typed the text fromthe spoiler
Then I entered the next part mount -o remount,rw /mnt/extsd /mnt/extsd
but I got an invalid argument error
What is wrong?
