I just rooted my phone and this guide was very helpful.
- After formatting your phone, boot into recovery through TWRP as my phone keeps bringing up the "no command" error screen if I use "Vol Up + Power"
- When that happens, hold power button for 10 secs, your phone will either turn off or reboot, flash TWRP again and continue.

Having issues: At the top of the screen its written in red letters as overlay: "TEE key not write Google key not write"
I already applied the "fix Orange state" fix.
Any ideas?

Actually I am using a CubotX19 S and finally I went back to stock rom. That fixed the issue.
However, when I flashed Stockrom I noticed at loading of MT6763 scatterfile, that there are 2 sections having "tee" in their names (see screenshot).
Maybe it would be enough to just flash one or both of those two sections.
I did not do any further research, but maybe this hint os of help for others .

BTW: my screenshot says "Download only" in the Droplist. Actually I flashed using "Firmware Upgrade"

best regards,
bul

Try the following at your own risk

You might have a problem partitioning the phone memory
format your phone
flash your phone
select : format all + download

View attachment 5188523
the latest firmware for CUBOT X19 upgrade 2020-04-21
format your phone

Then try again according to the instructions in the next topic
TWRP 3.3.1 + Root CUBOT X19
also i saw someone say that this vbmeta is android 9 thing, but cubot x19 came with android 8.1, should it even have the vbmeta partition? how could i create that partition?
