Anyone attempt to unlock the bootloader, root, or install a custom ROM? I asked Lenovo support about unlocking the bootloader and they said it can be done but would not tell me how. :) I don't want to buy this until I know I can root it. I am looking at the Tab P11 Pro, but that does not have its own forum (yet?)

For "Pad P11 Pro" (or XiaoXin Tab Pro flashed with P11 pro rom), you can follow instructions here to install twrp and root.

Except for step "4. Unlock bootloader" where I had to use this command instead:
Code:
fastboot flashing unlock

And I didn't do step 6

Don't forget that unlocking bootloader:
- wipes all data
- disables widevine Level 1, so Netflix and other streaming services fallback to low definition.

And there is no custom rom that I know of.

I am a tad confused on something, though - GSM Arena says this tablet has LTE, but the Lenovo website makes no mention of LTE...
Oy, I found the answer in a review... " in certain regions outside of the US, you’ll be able to buy an LTE-ready version of the Tab P11 Pro "
So, no LTE in the US version - which means no use to me. Guess I'll have to wait for the Xiaomi Mi Pad 5 Plus later this year.

Whatever the bootloader has to to with the DRM crap called Widevine. But as long as there is no LineageOS or any other custom rom with more features I don't see why I'd unlock the bootlader atm. I wish there was one, security patch december on a new device is not acceptable imo...

Is there a way to debloat the existing rom?

Are you successfully to unlock bootloader & root with magisk??
I'm new with Tab P11 Pro, but can't unlock on ZUI website, also can't find out how to unlock bootloader on internet! Please tell me this method, if you use "fastboot flashing unlock", really can be unlock bootloader? Do or didn't do step 6, have any difference??
And you said "But the widevine thing made me go back to the locked bootloader", what is widevine thing??
Thanks!!

Yes, magisk was working great.
But the widevine thing made me go back to the locked bootloader
Hi, I own the Pro and would like to root. If I root with this method, after rooting, if I lock the bootloader again..... Do I still have Root? (and if yes: with what command did you relock the bootloader & does (after relocking) netflix and stuf run high-res againg?

the stock rom looks fine, but I'm concerned for updates, lenovo is known for forgetting to update the tablets, also loosing the sound quality will be something to be considered by a future rom developer

Hi, relocking the bootloader is like doing a factory reset.
You lose all apps and data (and root, obviously)

    ...And there is no custom rom that I know of.

    Were you able to root the stock ROM with Magisk?

    This tablet is currently on sale for $100 off!
