Hi all,

Anybody had Root this device ?

irh which method ?

Thanks
[Android Q&A, Help & Troubleshooting] aryanhington:
have you unlocked the bootloader?
[Android Q&A, Help & Troubleshooting] diabolyk34:
No,

I have juste received the tablet, so just put the developer options... Lol

where did you purchase it from?
[Android Q&A, Help & Troubleshooting] diabolyk34:
From Teclast seller on Aliexpress.

Why ?
[Android Q&A, Help & Troubleshooting] aryanhington:
to start with, unlock the bootloader
[Android Q&A, Help & Troubleshooting] diabolyk34:
Ok

But is there a tutorial to unlock bootloader and to root with Magisk or another ?

before you can root it, unlock the bootloader using https://forum.hovatek.com/thread-32287.html
[Android Q&A, Help & Troubleshooting] diabolyk34:
There isn't another way to do it ?

Cause I haven't Linux...

Perhaps on windows ?
[Android Q&A, Help & Troubleshooting] aryanhington:
as it needs a shell script you'll need to use linux, install ubuntu on virtualbox?
[Android Q&A, Help & Troubleshooting] diabolyk34:

And after bootloader unlocked what should I do ?

Existing a lineageos for this tablet or another custom ROM ? Cause I can't have adaptative luminosity on it

flash a GSI ROM if you want

I've the P20HD(N9H8)_Android 10.0_EEA_V1.04_SZ, they are the same?
[Android Q&A, Help & Troubleshooting] Aniol83:
It seems to me that all P20HD versions are boot.img, vbmeta_sign.img files universal. The operation, however, is strictly dependent on the software version: v1.05, v1.06, v1.07 ...

You will not use the boot.img file from v1.04 with v1.07.

In the same way, you will not update Magisk to a newer version from Android, because the control sums change and the equipment will not start. You will need to upload the boot.img file again for repair
[Android Q&A, Help & Troubleshooting] davideakc:
If you want, I can try to make the custom vbmeta and boot for you based on your P20HD version.

But I can't try them because I don't have the v1.07, so you have to try them and you have to tell me if they work.

If the files will not work, you can just use UpgradeDownload to flash the stock ROM.

Just upload here your stock vbmeta-sign.img and boot.img :)

Hi,

for now I've uploaded only the vbmeta-sign-custom.img. Try to flash it via fastboot with "fastboot flash vbmeta vbmeta-sign-custom.img" command and see if the tablet works.

Then I made a mistake, I don't need the stock boot.img, but the one patched with Magisk app.

Give me that file and name it "boot_patched.img". I wil try to edit it for you.

But it seems to be suitable only for N6H7 running V1.08. On my tests, the boot.img does not differ from models, but they do differ from versions.

If you are using V1.06 you can use the boot.img and vbmeta.img made by me, which I posted on 4PDA too:

[Android Q&A, Help & Troubleshooting] Marika-Isa-Bell:
can you send me firmware to N6H3 ??
[Android Q&A, Help & Troubleshooting] raenye:
Spent all day signing and flashing vbmeta files. Now I got it working.

boot.img and vbmeta-sign.img were taken from P20HD(N6H1)_Android 10.0_EEA_V1.07_SZ.rar; I have N6H3 and it works fine.

vbmeta-sign-custom.img was generated using the same public keys as the original vbmeta-sign.img, except for boot partition, which was changed to use the public key of rsa4096_vbmeta.pem (sha1sum = 2597c218aae470a130f61162feaae70afd97f011).

boot.img was patched using Magisk 24.3, and then signed using rsa4096_vbmeta.pem.

To use this, either flash v107-vbmeta-sign-custom.img to vbmeta and then v107-boot_magisk-24.3_signed.img to boot using fastboot, or using SPD Research Tool (see below). No need to flash the entire firmware, just these two partitions. User data is unharmed by this.

If you want to update Magisk, don't do Direct Update, but rather patch boot.img (from the firmware) and sign it using avbtool.

Command for this (need Python 3):

./avbtool-1.2-python3.py add_hash_footer --image magisk-patched.img --partition_name boot --partition_size 36700160 --key rsa4096_vbmeta.pem --algorithm SHA256_RSA4096

By flashing stuff you take risks, don't blame me if it doesn't work, but here's return-to-stock troubleshooting in case it doesn't work for you:

Download SPD Research Tool (I used R25.20.3901).

Download the firmware from Teclast (1.23GB zipped, 3.12GB unzipped). You only need the drivers and the firmware.

Run SPD Research Tool (not Upgrade Tool), load firmware.pac (takes 30 seconds to decompress pac).

Click Settings, uncheck Select all files (FDL1 & FDL2 remain checked), check VBMETA (not VBMETA_system or VBMETA_vendor) and BOOT (not UBOOT), click OK.

Click Start Downloading, hold Vol-Down and connect USB cable. You can release Vol-Down once it starts flashing.

When done, remove USB, click Stop Downloading, power on tablet.

You can use the same method to flash the modified files, just use them instead of stock boot.img and vbmeta-sign.img.

If you messed up something, flash the entire firmware.pac, not just 2 partitions.. This erases everything (user data too), and you'll lose your serial number so you have to unlock bootloader again. IMEI/MAC are not lost.

You mast use latest Android SDK Platform-Tools from: https://developer.android.com/tools/releases/platform-tools (because of bugs in --disable-verity --disable-verification)

My simple script to updte to latest version:

wget -N -P /tmp https://dl.google.com/android/repository/platform-tools-latest-linux.zip
unzip -o /tmp/platform-tools-latest-linux.zip -d /tmp
cp -r /tmp/platform-tools/* /usr/local/sbin/
rm -rf /tmp/platform-tools*
#--------------------------------------------------------

After updates make sure you are using the latest version adb / fastboot.

after: 'adb reboot fastboot' UNPLUG AND PLUG IN THE CABLE !!!

you should try to run the commands several times until the output is error free.

Example without error:

fastboot --disable-verity --disable-verification flash vbmeta vbmeta-sign-custom.img
Rewriting vbmeta struct at offset: 0

I believe that your version came with the Playstore and that you flashed the 1.03.

Now that you realize (too late) that the 1.03 is without Playstore, you are upset because you've be trapped.

Think again: You don't need Google with all its spying/telemetry tasks running in the background.

Google "services" and all of their background tasks stuff are nothing else than a NSA extension/plug-in.

Google is "open bar" for NSA motherf*ckers who violate Privacy Human Rights of ordinary people like you and me every day.
