With Locked bootloader? Certainly not. Unlocking and then re-locking again is not difficult/will not break warranty, downgrading however does break Warranty if they found out.
If you decide to go with unlock/relock process, All you need to start is to look here: Poco X3/NFC index.
Before you begin though, first Connect your phone in fastboot mode and use:
Code:
fastboot getvar anti
to check Anti Rollback counter. The output should be 2.
If it is less than 2, then unfortunately you cannot downgrade to Official MIUI A10 safely. (There
are methods, but they cost money and/or carry a high risk of bricking)
My advice is to unlock your bootloader and flash a Custom ROM. MIUI A11 is not made for the Snapdragon 732G Chipset that comes with your device, it is full of bloatware and stuters at every corner. In comparison to the custom ROMs here on xda, which are very smooth last and longer in battery life. Most important of all, a lot of them pass Safetynet/are google play certified out-of-the-box.

hi all,
anyone ever use mi mix 2s global rom with 5 digits version of miui ? example 9.5.4.0.0 . is it the real global stable rom ? i checked the phone was unlocked shown on the bottom when i turned on the phone. Can i just flash to other rom with miflash tool ??? seem the phone bootloader is unlocked.
thank you for the attention.
That and the fact it came unlocked sounds fishy. You can miflash a rom for sure. You'll want to find out if it's truly a global model as well because if its a China model you will brick the phone if you relock the bootloader with a global rom.

thank you for the replied.
seem its china model because the phone was unlocked...so how could i flash the rom if i want a global stable rom like the real global version of mix 2s ??? TWRP is the last method???
You can use miflash to flash global stable ROMs, they will work just fine, just DO NOT AT ALL attempt to relock the bootloader unless you are back on China stable.
Also watch miflash... Down the bottom right you have the flash, clean and flash, flash and lock etc. Absolutely make sure it is not on a lock option. It's easy to do there by accident if you don't check.

Immediately try to flash official global stable !!!!!!
Like it was said DO NOT lock bootloader until you do get on official rom
You phone came with 3rd party FAKE miui (yes thats the name of this rom) it may contain malware and all kind of bullsh*t
My first Mi 5 came with it, I studied it so trust me. Flash global stable!!
You can flash twrp via fastboot and then flash miui eu weekly, that a way to get rid of this nasty fake crap!!!

Dude don't tell him to lock the bootloader.
Chinese versions of the phone only work on global with the bootloader unlocked, If he locks it the phone won't boot and he won't have any way of installing the chinese rom because the mi account isn't bound. So he'll end up with a hardbrick that could only be fixed with a special mi account and EDL mode.
Tl;Dr DO NOT LOCK THE BOOTLOADER YOUR PHONE WILL BRICK

Thank you for the useful information, i will remember it.
Im now in FAKE miui rom, so i just need download the global stable rom and flash over this fake rom through Miflashtool? Will it relock the bootloader? Im still not sure if my phone bootloader is unlocked or not. But when i turned on, i see unlocked msg on the screen.

I wrote "DO NOT LOCK" can you read?
And how are you sure he is using the china version? Cause it came unlocked ?? Every version of the phone can come unlocked if a 3rd party was doing stuff on it...

Hi guys,
Just got the Poco F2 Pro, the device feels and looks great, but coming from an OnePlus 6T I've been trying to read a bit more about the Xiaomi unlocking & flashing tricks, as it's a little bit more complicated (and it looks like I got time, since the MI unlock tool will take 168h to let me unlock my bootloader) but there isn't much movement here in XDA so far. What are the ways to hard brick and what should I double check before flashing stuff?
I've seen some people reporting bootloop after flashing TWRP, both 3.4.1B and 3.4.2B, but it looks kinda random and I assumed it can be fixed through fastboot or MI flash tool.
I'm on global MIUI 12 (12.0.1.0.QJKMIXM). Can the Xiaomi.eu ROM be installed on any variant? Are there regional locks when trying to flash ROMs with different bases through TWRP or MI flash tool?
Does it use A/B or regular partitioning?
From what I understand, the only way to actually hard brick (which is a dead end for me, because there is no support here in Brazil) is to relock the bootloader and mess something up. I read that it's possible (and looks like the default behavior) to relock the bootloader through the MI flash tool. Is there any other way to relock the bootloader that I should be careful with? Can it happen accidentally through TWRP or when updating somehow?
Thank you very much!

I'm waiting for my Poco delivery! Coming from OnePlus 6 ?
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?)
I'm thiking of buying the XiaoXin Tab Pro (same tablet/half the price), but i have the same questions as you.
I'm in exactly the same boat, did anyone find any more info?
For "Pad P11 Pro" (or XiaoXin Tab Pro flashed with P11 pro rom), you can follow instructions here to install twrp and root.
unofficial twrp 3.4.2 Root Lenovo TB-J706F - unofficial twrp
Download unofficial twrp 3.4.2 root Lenovo TB-J706F aka Lenovo Tab P11 Pro, user who own Lenovo TB-J706F can root it by following below guide
unofficialtwrp.com
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.

Were you able to root the stock ROM with Magisk?
This tablet is currently on sale for $100 off!
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.

Yes, magisk was working great.
But the widevine thing made me go back to the locked bootloader
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!!

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)
I am also having the same problem.. help .. haha
So, is there any hope for LineageOS on P11 Pro / Xiaoxin Pad Pro? I'd say that if any android tablet deserves it, this is definitely the one. It has superb hardware (honestly it feels like handling an iPad Pro) and a very sensible price on many distribution channels.
i have an issue with the bluetooth that can´t repair anything and it´s possible to be rom´s fault, the recommendation is to change the rom to another one but yeah, there is no custom roms for this device yet :s

Hey there, I know this post isn't recent, but I just discovered it and was hoping to ask a question or two.
I just picked up this tab, the J706F model, and I would really like to root it. However, when following that websites steps, including your experience of not flashing step 6, it still doesn't work. I get booted into the bootloader everytime, and there is no way to resolve this but to rescue the device back to stock. I've successfully unlocked the bootloader, and I have quite a bit of experience with tinkering around, but this has got me stuck. I can't seem to get Magisk on here. TWRP on the other hand isn't an issue. I have that installed and it works just fine.
Any advice would be greatly appreciated for getting root on this device.
Now magisk is much complicated for me now days and I don't want to root my phone
I have indian version poco X3 pro I flashed eu rom but saftynet failed. so can I lock bootloader with eu rom and this will fix saftynet failed issue fixed .
I don't want to root my phone and magisk method is looking complicated now days so that option is not my choice so plz help me with that
Locking the bootloader means phone gets forced to boot into ROM what was pre-installed.
I think eu rom should have resolved the safetynet, you should ask in the eu rom forums.
From my limitted knowledge, if you re-lock you must only flash the same ROM that your phone was sold with, or you'll have a brick...
Unless I'm mistaken, once re-locked even EDL will not be available, so it would be hard brick.
Don't do that unless you know exactly what you're doing.
Try at your own risk though, I heard new xiaomi devices don't allow people to lock their phone, even if you want to the fastboot will simply not let you do it. On slightly older xiaomi device, it does let you lock the phone but good chance that you are stuck with that rom because you can't unlock it.

Xiaomi's Anti-Rollback Protection Explained: How to avoid bricking your phone
All Xiaomi smartphones and tablets will have anti-rollback protection enabled. What is it and how do you avoid bricking your device because of it?
www.xda-developers.com
enable magisk hide..... I passed safety net with eu rom and magisk.... if you've installed xposed framework tho...then it'll fail no matter what
This is a brand new China hardware GM1910 OnePlus 7 pro. 256g 12gig ram model.
No matter how precisely I follow directions it just gives buzzarre responses.
Clues anyone?
The first time it soft bricked a few days back was my fault.
I had android 11 OxygenOS and tried to flash pixel recovery and ROM.
Supposed to have OOS 12.1 which I had this time.
After I flash the pixel recovery it acts all bizzare and refuses to boot to the recovery.
Then it shows this?
I only have the picture. Fastboot mode. And power off.
Is it because it's Chinese? Off AliExpress.
I'm feeling like I've just bought a lemon?
From the OnePlus forums:
GM1910 is the Chinese variant OnePlus 7 Pro running HydrogenOS (with GM21 build tag).
It is possible to flash both GM21AA (global) and GM21BA (EU) OxygenOS firmware on top of the HydrogenOS using the Local Upgrade method.
Bootloader unlocking is not necessary for switching to OxygenOS.
After conversion, you'll get OTA update from the respective branch.
Have you considered trying this first and then maybe try flashing other ROMs after getting to know the device / reading more?

It's my first ever OnePlus an I bought it as a hobby cellphone. The directions for unlocking the bootloader worked on it. This happened after the pixel experience failure. When I tried to relock the bootloader and it acted wierd.
I could not find any information on the GM1910 model.
Thanks for starting my investigation.
Anything helps at this point
I don't know if the GM21AA unbrick tool will work on the GM1910 tho...

It does. I think I tried a similar tool to this one 2 days back and after trying various button combinations achieved a boot.
Do you know if this model can boot PE 12 or 13 or will I just get another brick?
The whole point of the purchase was to have an easy time with unlocking the bootloader an trying custom roms.
Was not expecting a nightmare?
My last OnePlus was 8T and 9, and since then I got Google Pixels and other phones...

I don't know. Just trying to help with the stuff I remember. I mean, you can try and as long as you don't do some crazy stuff and hardbrick it, you can always go back with the unbrick tool. Did that a lot of times when doing ROM hopping back then. The OnePlus devices have an easy to unlock BL, and that's good. But flashing them was a pita (for me). Now on the Pixels I had and have all is much more easier (IMO).
Follow this here (says GM1910 is supported by PE 13)
https://wiki.pixelexperience.org/devices/guacamole/
There is some installation guide too.
Thanks for all the help I'll go see some options. It's very hard to find accurate I formation about this phone as it's reached legendary status. I really like it dispite it being power hungry.
I was just hoping for a few options besides the stock ones. Nothing too crazy.
It's a beautifully performing cellphone dispite being near 4 years old now.
I will keep Google pixel in mind. There are ones the same age as my OnePlus that are dirt cheap. If I find them as easy to work with as you have I might buy a more modern one.
I just wish I knew about the bootloader.
It seems to be permanently unlocked now which could make life difficult? No relocking guide works.
Thanks again

I may of ruled out pixel experience official as I seem to have a permanently unlocked bootloader even when bricked. I don't know?
It's bricked twice now trying official. Might have more luck with unofficial
No luck with that tool. Off for night shift. Tried it 3 times. I put OnePlus in the drawer. Last time the hardware sat in the drawer an bang. 2 days later got a boot. Hoping for magical booting properties again

Try installing LineageOS, not sure if it'd help, but it's a good test I'd assume.
Info about guacamole | LineageOS Wiki
wiki.lineageos.org
Also, using MSM tool should normally relock the bootloader. Are you sure your bootloader is actually unlocked when you use it?

It's the unbrick tool linked earlier in the thread.
Yes I tried that but still get the system destroyed message. It's bright and my little Oppo A96 4g did it's best.
Not sure if you can read it but it says internal system an recovery destroyed.
I did wonder if it's still locked but just saying unlocked because of all the different activities trying to revive it.
I just hope it's not unrecoverable as I just got it and waited a month. So that would be horrible
