Question Relock - Redmi Note 11S 4G / POCO M4 Pro 4G (fleur)

Hi, it is possible to unlock the bootloader without losing data, in any way from Linux. or MTK from Windows, or else thanks guys wait.....

Unlock or relock? Your post title is "relock" but in your post you've said "unlock".
Apparently you can use MediatekBootloaderUnlock to unlock your bootloader without wiping your data, but I haven't tried this.

[Q] Can i Use the Bootloader Unlock tool

i have x10a that is not unlocked(i.e still locked to AT&T).
can i use the bootloader unlock tool or should i wait.
thanks
edit: i unlocked bootloader using qsd8250_semc and it worked fine.
I have a similar question.
I've unlocked my x10 through imei unlock. Any problems to use the bootloader unlock?
i think you should wait.
as stated you must be unlocked using setool to use the bootloader unlock

that's what i was thinking, if in a couple of days nobody tries to unlock bootloader having the sim unlocked with imei method (the only one available a year ago) i will ask the devs.
thank you
Actually, no need to be unlocked your sim can still be locked. What will happen is if you unlock the bootloader using the_laser method...you won't be able to unlock sim in the future as of now. If your sim is still locked and you don't care about unlocking sim...go ahead and unlock bootloader if you want.
If you unlocked your phone using third party to get imei number and what not...then you most likely cannot/should not try and unlock bootloader, atleast not until someone releases a fix that allows you to do so without losing radio signal.
the_laser actually posted a file that allows you to see if your eligible for bootloader unlock.
EDIT: didn't see your edit...haha oh well will leave this here for someone else.
I'll try tomorrow with the tool to know if i can use it and post the result here. Thank you
Ok, yes please post reply, I would like to know. I also read it shouldn't wipe anything... still ain't safe in unlocking it lol
i've tried with the tool to know the lock certificate and as i unlocked the phone with code, not with other tools i can unlock the bootloader. If you have unlocked your phone through imei code, at least for me, you can unlock the bootloader
I can confirm it works via the method in the OP of this thread for x10a on AT&T. Just follow the directions EXACTLY. Worked first try for me

No it will not wipe anything as long as you do it properly.

Same here. I got it unlocked but had to go back to 2.1, for some reason it wouldn't move forward with the batch file after I did the BB downgrade. I still got it to work though as long as you have a general idea of the steps and what to expect next.

[Q] Xperia Z Ultra bootlloader/Root questions

Hello everyone.
I had posted this in the Z forum, not realizing there was a Z Ultra forum. So I will just quote my previous post and add some info at the end:
Hello guys. New guy here with an Xperia Z Ultra phone.
I'm trying to load the Paranoid Android custom ROM.
Had a couple of questions:
1. I went thru Sony's instructions to unlock the bootloader. When I ran the fastboot -i 0x0fce oem unlock (e-mail code), the first error message I got was "FAILED - Remote - Command did not succeed". So I tried the exact command again, and then I got "FAILED - Remote: The device is already rooted".
I have searched high and low, and cannot seem to find any way to verify that the bootloader is now in fact unlocked.
2. Reading the instruction on how to install CWM/TWRP recovery menus, Every single list of instructions includes the following "This tutorial is only for Sony Xperia Z Ultra with 510 and 493 LTE firmware. Do not use it for any other carriers or variants"
Again, I have searched high and low to find a way to confirm what firmware version I have. All I know is I have the C6806 model, with the build number: 14.2.A.0.290
So can someone please help out a very confused guy here? I don't want to brick my phone by accident
So far it's still working ok

So far, after doing some major searching, I seem to have found that I currently have "290" Firmware, and that this Firmware is currently NOT able to be rooted. Is this correct?
Also, I still have not found a way to verify wether the boot loader actually did unlock or not. From what I have been able to read, it seems that if a proper boot loader was in fact, unlocked, it would have wiped all the data on my phone along with the SD card data.
So far, it seems everything on my phone is intact. So does this mean the boot loader unlock command failed for me? If so, why did I get the reply "this device is already rooted?"
I can't believe how difficult it is to root a damn Android phone! Jailbreaking an Apple device is 10 times easier!
First of all, it's usually pretty easy to root Android devices. In most cases it's only a simple click, but sony has done a good(?) job at fixing exploits, so it does it much harder for us.
Second, you can check if your bootloader is locked or unlocked by opening the dialer and insert *#*#7378423#*#*, go to "Service Info" and then "Configuration". If your bootloader is unlocked, it should say "Rooting status: Bootloader unlocked: Yes". It's easier to use Flashtool to unlock the bootloader if you're having issues using a terminal.
You'll find the rest here (including bootloader unlocking). If you need some help, ask in that thread.
If you aren't boot loader unlocked then "BACKUP TA PARTITION" from My Lord's guide @LordManhattan
Just incase you need to re-lock it for service

First of all it' pretty damn complicated and unrewarding to root a Sony device. Not all android but Sony definately. We checked, bootloader is unlockable. We unlocked and relocked bootloader prevoiusly because there is no robust, easy-to-install ROM for ZU. But time to time we try to root it.
Now, the question is the same: what should we do to re-unlock the bootloader if anything is OK, but flashtool says "Command did not succeed" for the first time and "Device is already rooted" for subsequent times at unlocking?
Please write some advice about the question, not about TA backup and your success. Thx!

Oh, are we demanding help now?
Bootloader unlocking is a straight forward process. I've had a couple of strange errors in Flashtool while trying to unlock the bootloader, but just close Flashtool and try again. Also be sure to be on the latest version of Flashtool.

No sir, not at all. I wrote please, no demanding. Well yes, I'm a bit picky because there were no answer and I usually find some on XDA. Besides I used custom roms on Samsung devices for years (SGS2, SGN, SGN2) and I was disapponted when I bought my XZU that there are very few roms and I couldn't use them (I managed with very hard work to go back to stock in 9 hours after unsuccesful flashing).
So there is some basic problem every time. Like trying to root but cannot re-unlock because of some mysterious errors with no solutions.
Enough of my problems, your answer is much appreciated, will try to re-unlock some time. Thx!

Oh, i get that. I came from Samsung myself, and this is my first Sony device ever, so I've had some issues myself. I've gotten the same error message(s) as you before, and i think i restarted Flashtool and rebooted my Ultra and it was back to normal again - i think, but it "fixed itself" after trying a couple of times, so don't give up. It's also important to always be on the latest version of Flashtool.
It would also help us if you could tell us what you're trying to achieve, so you don't end up spending 9 hours on something that takes 5 minutes
@Champdor
From what I can make out you have never managed root your phone or back up the TA. If the latter is true then there is very little point in relocking the bootloader.
Yes the process is a little harder than Samsung, but the last device I rooted was a ZTE, and that was even harder to root and flash from what I can remember (yes this is my first Sony device as well, and I will buy another...)
Take you time and read the stickies that we have written and all should go well. Don't be afraid to ask (intelligent) questions if you get stuck, and read some more

I have not had this error so have not tested this, but what happens if you flash a full FTF and wipe everything then try to unlock the BL?
And remember that you can take a backup of the unlocked BL (re member to name it as such) and just flash that to unlock again. Doing it this way you don't get the format that happens when using the unlock code.
I followed this post to downgrade, root, i use Backup TA v9.10 to backup DRM Keys, use Flashtool 0.9.14.0 to unlock Bootloader, then to flash other Rom's (stock and customs), came back to Stock Rom .681, relock the Bootloader with Flastool 0.9.15.0 flashed the last .757 and unlock the Bootloader again with no kind of problems using Flashtool 0.9.15.0....

You just back it up as you would for a locked BL. Just remember to make sure you name them well so you know which is the locked one and the unlocked one.
NEVER use a TA backup from another phone, you WILL HARD BRICK IT

Relocking Bootloader V20j?

Hi, I awant to root my H901 by unlocking bootloader (V20J). However, my concern is can it be locked again as I will sell it after a month or so and I don't want any bootloader unlock alert at startup? Has anyone tried to relock? Plz let me know, thanks.

To relock the bootloader follow the following instructions:
Put your phone under the fastboot mode
enter the following commands: fastboot oem lock
Keep in mind that while your boot-loader is locked, you will not be able to root or flash ROMs to your phone.

Thanks. Yes I can unlock the bootloader again to gain root but I have read in unlock thread guide that relocking might have unknown results. Have you or anyone else tried relocking personally?

You should not re-lock you bootloader if you have root but if you are going to trade in your phone or sell it then you should definitely re-lock your bootloader after you flash a stock ROM.
Bump..... Anyone successfully relocked bootloader without any error and got rid of unlocked bootloader at startup?

Does unlocking bootloader with the official tool wipe my data?

Although the description says it should, I did the process on another Asus phone (Z010D) and i my data was not lost.
As I know unlocking bootloader either through official method or unofficial wipes the data
