Dear Gouwa, I got my VIM Pro with "Vim_Marshmallow_20170303" which is not to be listed on http://docs.khadas.com/basics/FirmwareResources/.
So I want to create a full backup including my aps, settings etc before I flash other roms. I'd like to do that with TWRP, since I found on http://freaktab.com/forum/tv-player-support/amlogic-based-tv-players/s905x/610101-khadas-vim-tv-box-amlogic-s905x-quad-core-one-for-the-geeks/page8 this:
"TWRP 3.0.2 for the Probox2 Air running nice on the Vim. Props to Abdul Pt for that.
And it works: backed up and restored system, data and boot in about 3 minutes in each direction."
(Same here at http://forum.khadas.com/t/backup-restore/137/3.)
So I tried the official TWRP app to flash this recovery. But later my VIM did stuck during boot into recovery, just displaying the letters "VIM". After I booted nomally without issues, I used the TWRP app again to re-flash the backupped original recovery, which did work. The device now works normally again.
I guess I could use your the USB burning tool to flash TWRP via PC, (http://docs.khadas.com/bootcamp/UpgradeViaUSBCable/), but I read also about booting from a SD card with an .img-file there. I think this would not change my current system before I can back it up totally. But I can't find any (detailed) infos how create such a card for Android. Any help with TWRP on Android 6 would be highly appreciated.
Sorry for bothering you personally, but I have no clue where to post this here best. Please move my question to a suitable post if there is one.
Thanks in advance and also for this nice little great computer!
