What recovery to use for unofficial unlock?

Hi, I got a redmi note 3 pro, and was thinking about flashing Santosh's CM on it, but I havent got unlock priviliges so I'll need to use the unofficial unlock for it. I'm just wondering which recovery to flash? TWRP obviously, but if I remember correctly there was 2 different versions for TWRP on unofficial unlock, 1 for backing up and 1 for flashing.
Cant seem to find the thread so I thought I'd ask here..

How to flash Chinese Developer ROM over Global rom to unlock Bootloader?

I had applied for permission to unlock bootloader officially and i got permission two days back.
When i try to unlock via MiUnlock app, it stuck at 50% and said Couldn't verify the device.
I searched on google and i found something like i should be on Developer Rom to unlock. So i flashed the Gobal Developer Rom through System Updater. Again i tried to unlock the phone, same error. Then i found , i should be on Chinese Developer rom. So again i tired to flash Chinese developer rom but this time it failed when i try to flash through System updater.
Can anyone tell me how to do?
Thanks in advance.
No matter how u try, it all depends on luck. With chinese developer rom I was able to unlock mine but not my friends RN3. The real truth is that xiaomi doesn't want to you to unlock otherwise why to complex a one command process. Its better to flash zxc twrp with miui rom flash method without unlocking or unlock it unofficialy.
Now to your answer if you want it. You can flash chinese developer rom via edl method through mi flash
Just flash via EDL and choose flash_all in MiFlash.
I had 50% problem with unlocking many times and it was always something to do with drivers or bad connection...
i think need sign in account has unlock permision to you phone and wait 1,2 days

Thanks for your information.
Flashed the chinese rom using MIFlashTool. Still no luck.Same error.
Couldn't verify device.
ZXC twrp will help to install Lineage based ROM without any problem?

Help with Redmi Note 3 (BL/TWRP/ROM)

Hey everyone! In the past, I have tried to unlock my Redmi Note 3's Bootloader via the official method (yes I have permission), and also fastboot oem unlock command. Nothing seems to work, and I am going to follow some tutorials to get ZCX TWRP on my phone. Provided it works, I need to know some things:
1. Will those tutorials (they all do same thing; flash ZCX TWRP via Mi Flash EDL) unlock bootloader?
2. If not, will I be able to flash custom ROMs like AEX 5.7 via recovery?
3. Can ZCX TWRP be replaced by official TWRP?
Help with getting rid of MIUI (and my locked bootloader) would be appreciated.
Cheers!
Same thing happened to me... I accidentally locked my bootloader while flashing with MI flash. And now mi unlock tool saying "this account couldn't be used to unlock bl" (I too have unlocking permissions ??)
Now I'm stuck with stock miui rom??

I have this same error! Anyway, I'm now on official TWRP 3.2.2-0... Need to know whether it's safe to allow modification of System, and whether I can flash stuff.
Yes you can, almost 90℅ of redmi note 3 users have unlocked unofficially , just dont flash miui rom with twrp

How u know 90% are unofficial unlocked ?
Update: It works
I decided to try for myself, and successfully flashed AEX 5.7. Gapps is giving me some problems but that's probably because I installed the stock zip. Micro will probably be more stable while retaining face unlock feature. Thanks to everyone who helped, and the awesome community.
Because of error current account cannot unlock this device

Revert to stock from Lineageos 16 official.

Greetings,
I am planning to get a pocophone f1 and install lineageos 16 stable. Questions are:
1. Will it be possible to revert to the stock rom (to prove warranty or if i were to return it)?
2. How do you revert?
3. Is there a flashing tool for doing it?
4. Anyone done it?
Kind regards
1. Will it be possible to revert to the stock rom (to prove warranty or if i were to return it)? Yes
2. How do you revert? Use Mi Flash Tool and fastboot ROM
3. Is there a flashing tool for doing it? http://en.miui.com/a-234.html
4. Anyone done it? Many times, if you don't want to lock bootloader while doing it, don't choose clean all and lock
Cheers!!!
Thanks for answer.
I've found that to flash lineageos you need to flash a pie vendor. wondering in case of a revert, whether you need to flash stock vendor. I guess it gets flashed if I use flashtool and flash fastboot rom, correct?
secondly, if i relock bootloader, to reunlock, do i need to repeat same process as first time unlocking? or is it just a "fastboot oem unlock" command?
thirdly, should I be worried about xiaomi "anti rollback" feature? will it just prevent downgrade?

Yes, the tool would take care of it.

Same process as before, fastboot command doesn't work on Poco.
thirdly, should I be worried about xiaomi "anti rollback" feature? will it just prevent downgrade?
No, there is no "anti rollback" for Poco

Ans1 , yes you can revert back anytime, manytimes (always take backup because Miui encrypts data partition and custom rom has to wipe it so chances are you will loose you data .... but last week i flashed MIUI 10.3.4 Global Stable from lineage and then flashed havoc. i didn't loose any data (used latest twrp and magisk19 beta)
Ans2. there are 3 ways, download recovery rom and simply flash it via twrp ( which is the most common), OR download fastboot rom and flash it via miflashtool (by putting fone in fastboot mode) BUT this way you will DELETE ALL THE DATA and there is one button on MIFLASH called "flash and LOCK" if you by accident didn't uncheck it, chances are your boot will be LOCKED, so becareful. ---- the third method is EDL but you will never use that, it involves putting fone in edl mode (back panel is remove and two short points are touched via wire on motherboard and usb cable is plugged in and then fastboot rom is FLASHED by miflash tool, this usually done on BRICKED Xiaomi fones and MIFLASH asks for AUTHORISED ACCOUNT , which usually only few members have ,,, so this third method you will not use! ...
Ans3.. the popular tool to flash fastboot rom in fastboot mode and edl mode is MI FLASH (latest came out during May2018) but
(a) if your redmi/mi fone is mediatek base then you can try SP FLASHTOOL also! (never done)
(b) if your redmi/mi fone is qualcom snapdragon like redmi3s/ redmi max / redmi6 series / redmi5 series (snapdragon 430/625/660 and now Poco f1 on snapdragon 8x) then you can use QUALCOM's OWN Flashtool https://www.qpstflash.com/ ... i flashed lenevo via qualcom flasher once and it was successful! BUTTTT its HIGHLY NOT RECOMENDED!!!!! ,,, for poco f1. just stating here for your information
Ans4. recently bought Poco so NO, but i have flashed my REDMI 3s via miflash tool (EDL MODE) and then Redmi Note 5pro, i have flashed in fastboot mode so it works but you have to patience, REDMI/Mi is UNSTABLE devices (unlike Sony or Samsung) , and can easily be bricked and many time there are no solutions on miui forums for strange errors coming / poping up in miflash tool... like "cannot send zero packet data" etc etc
summing up..
anything can go wrong even if you are flashing ! so whenever you are flashing any custom rom or miui via twrp/miflashtool ALWAYS "cross your fingers"

My phone is Soft Bricked !?

Hello , do not be tired
my phone is soft bricked and the installed custom ROM cant be run [ XIAOMI MI A3 ]
when I turn it on, it goes to the fastboot mode
can't go to the recovery mod [power+volome up]
OEM was not unlocked before this happened. that's why I can't unblock bootloader to flash by mi flash tools or install TWRP.
Please Help Me
If i understood corectly, you relocked the bootloader after flashing a custom rom?
Flashing a rom with a locked bootloader is not possible. Afaik, there's no rom for the mi a3 that support relocking the bootloader
there are too many variables to know what is the state of your device... i recomend you to use miflash tool to install stock rom (if you had android 10, flash android 10) and then try again to flash a custom rom... but this time unlock the bootloader and follow all the steps on the threads that show us how to install twrp or shrp.... good luck
