only android 8+ needs to use the keys to unlock, right or wrong? (isnt this because of google pushing the ANTI-ROLLBACK feature into android 8)
if i have a TECLAST M89pro on android 7, would i still need this key to unlock the bootloader>?

Hi, I have a fast question: are these 2 files enough to the root Teclast P80X?:

1. vbmeta_custom_signed.img
2. magisk_patched_recovery_custom_signed.img

Code:

fastboot flash vbmeta vbmeta_custom_signed.img

and

Code:

fastboot flash recovery magisk_patched_recovery_custom_signed.img

Yes, provided:
1. The steps that created these files are correct
2. You boot straight into recovery mode after flashing magisk_patched_recovery_custom_signed.img (you'll need to power off) else root won't be detected

You could also patch boot.img using magisk canary version. That worked for our copy of the P80X so you can just flash TWRP to recovery partition.
Don't forget to rename recovery-from-boot.p if you're flashing TWRP or rooting via recovery partition

Hi, I flashed 2 signed images: patched recovery.img and vbmeta-sign.img. Teclast P80X/Pie starts up normally (no root) and I cannot rename recovery-from-boot.p. Booting to recovery mode doesn't work via Power and Vol- button. No rooting...

Is to my device dedicated TWRP? If so - are they flashing instead of stock recovery.img? Have I to sign TWRP and vbmeta?

As explained in the guide, if you want to root via recovery then you need to go though the research download tool trick to get the tablet to power off. Only then can you attempt booting into recovery mode using button combo.
Mind you, the phone will just boot up when you try entering recovery mode from off state but you'll have root.

Another approach is to just patch boot.img using magisk canary version, sign it and flash to the boot partition

Thanks! How to go through the research download tool trick to get the tablet to Power Off?

Another approach - I can't verify the contents of a patched magisk boot.img (on Linux & Windows).

In terminal (Python 2) I got message:

Code:

Given image does not look like a vbmeta image.

or (Python 3)

Code:

File "avbtool", line 411
    b = 2L**32
         ^
SyntaxError: invalid syntax

The contents of a stock boot.img in avbtool is ok...

When I ignore it and sign patched boot.img I got this message:

Code:

avbtool: Image size of 36700160 exceeds maximum image size of 36630528 in order to fit in a partition size of 36700160.

Is patched img wrong because of new version Magisk Canary/Magisk?

Its the contents of stock boot you verify and use that info when signing patched boot.
