Good news !!!

Any special instructions for installation ?

Thank you for your work.
Did you use a prebuilt kernel from the official firmware to compile this?
Your tree appears to have a prebuilt dtbo and Image.gz.
I wonder if you actually compiled them. (Lenovo P11 normal variant kernel is half-baked, so if it works on your variant I may be able to utilize common lenovo stuff)

Are you wanting them compiled from source or do you want to use the Lenovo P11 ones ? I have them for the P11 Pro j706f from source if you want them. It compiled with no errors and barely a warning, I was not expecting that.

This is sad.
Are you from China? If so, does lenovo give kernel source code in china site? I can't seem to get the newest version in lenovo global site. Thanks

They are not going to open source

Binary?

Question Lenovo P11 TB-J606F Invalid serial number

Hello from Greece,
Yesterday i received my new tablet P11 (6gb/128gb) from a well know chinese e-shop (banggood)
And i have some questions.
The seller stated that model is not Global Rom, is third-party rom and support google play store and multi languages. It doesn't support Widevine L1 and ota update os.
but it came with the rom TB-J606F_S320029_210923_ROW (see picture bellow)

}
and after 5 minutes in the update section notifies me for a new version TB-J606F_S320158_220217_ROW.
After the update I login to my lenovo account and then I tried to register my device.
Questions:
1) When I put the serial number in the registration form it stated always "invalid serial number"... (see picture bellow)
2) How it recieve OTA update, is that an official rom against what they stated?
3) When I checked the DRM info app it stated that the current level is L1 (see picture below)
Thanks in advance

I guess the box says Xiaoxin Pad not Lenovo P11, if that's correct that's the version only sold in China and that's why your serial number is not recognised.
Your Widevine L1 means that your bootloader is locked, you can verify that doing a reboot to recovery, only official ROMs can be installed with bootloader locked.
In short you are not going to receive support because that tablet is not supposed to be sold outside China but since the hardware is the same as the one for global market (P11) and ROM installed is the proper Global you should receive normally OTA updates.
One thing you should check is if they properly set the region:
Check Region Unlock!! P11 [TB-J606F/L/N]
This method was shared by Koreans at the Ppomppu Forum. When Check Region Unlock is performed, firmware downgrade and update are free. Chinese ROM ZUI(12.6) check region introduce Global ROM 210805 check region introduce How To Guide (Check...

Question Worried I'm bricked. Please help

I'm getting desperate now.
MSM tools (EU/Global) get stuck at waiting for devices.
No ADB (unauthorised) or fastboot. In Windows device manager after holding power and both volume buttons for fastboot it's shows as this:

}
This is what it looks like when using the button combo power and volume up:
I'm at a loss. Had to buy a new laptop and everything to fix it.
Please help, someone. It's getting depressing now.
Drivers are fine by the way. All upto date. Only ones I couldn't find were the official OnePlus ones, but those should be automatically downloaded after plugging in right?

! is a driver issue.

OnePlus has finally launched its OnePlus 8 series successor known as OnePlus 9 and 9 Pro with a much-upgraded camera, processor, display, refresh rate,

Also, since your device is this far gone, it likely won't be recognized by the EU or global MSM Tools. Grab the Indian one for the 9 Pro.

After you flash that, grab 11.2.4.4 here and follow the instructions in the thread.

This method is outdated. You must use this method or you will run into problems...

If this doesn't work for you (make sure you try it with Sha256 checked and lite firehose unchecked), you will have to grab the downgrade package from the pinned post and either use the local upgrade tool or TWRP to flash it.

Thanks again for yesterday, mate. My hero for the day!

Two ways:
* To wait for OTA update or try to get it trough VPN for other country.
* Download Lenovo Rescue and Smart Assistant and to make clean install via Rescue --> Rescue tablet.
Disclaimer: Works only for global stock firmware. If you have ROW on your tablet - you can do this; if you have ZUI now - don't make it, you tablet will broken and you will cry

What country should I set my VPN too?

Sorry, I don't know. I use ZUI on my tablet.

I just did a regular check for update and it worked here in the States. Thanks!

Guys I got the update yesterday and look how broken the taskbar is:
Anyone know how to fix it? I got android 11 backup from lolinet but I don't know how to flash it without twrp. Do I have to use the lenovo recovery software?

Just got the update, complete with the broken taskbar Really don't like the white and not happy it can't be changed unless you disable dark mode - which I normally use all the time. Can't be good for the OLED display to have a bright white taskbar permanently on the display.

Does anyone know how to flash my P12 Pro back to android 11? I downloaded the android 11 image from here but do I have to installed TWRP and unlock my bootloader to be able to install it? I really don't want to root unless I absolutely have to...
I downloaded the Rescue and Smart Assistant but the only image it will allow me to flash is the latest android 12L image...

You can flash any rom with OFil/QPST.
Roms are here: https://mirrors.lolinet.com/firmware/lenovo/Tab_P12_Pro/TB-Q706F/
Unlocking and rooting no need.

My OP7Pro is GM1913.
And current build version is: GM1913_11_H.31
And I really want to avoid the MSM tool option as it's a bit complicated.
Any suggestions?
Thanks.
