I unlocked bootloader in official method. I flashed twrp and magisk. but after the latest Global beta, I've somehow lost both TWRP and magisk. that said, my phone is no longer rooted and the stock recovery is back. now i want to relock my bootloader. I never installed any custom rom. My question is, how to relock bootloader, and, if i do relock will all my data get wiped? like system reset or something? if so, is there any way to avoid that while relocking?
flash an official miui fastboot rom using mi flashtool and choose the option to clean and lock.
as far as I remember there is an option to keep data but you can backup everything to your PC before flashing

HI guys,
After being a sammy boy for years, Sony's android development is still a deep forest for me with all its bootloaders and secret keys.
I've got a rooted 5.0.2 with twrp recovery and just read somewhere, that this is enough to flash a pre-rooted 5.1. Is this true? No unlocking of the BL nor putting the DRM keys at risk?
Have a nice day!
If the "pre-rooted" 5.1 zip is all stock and has stock kernel, then you're good to go. Custom kernel and custom ROM requires unlocking the bootloader.
All you have to do is, go on TWRP recovery, wipe everything and flash that "pre-rooted" STOCK zip WITHOUT exiting TWRP after the wipe.

So as long as the bootloader stays locked, my DRM keys are safe? And flashing a rom through recovery will not unlock a bootloader in any way?

Hello,
I have installed the 6.0.1 beta but did not first flash a rom with a recent bootloader, hence I can't flash a recovery.
Is there any way to only install the latest bootloader, without first wiping my phone?
Thanks!
No !
Theoretically it should work, but It would be much more work than backing up and reflashing.
Of cause you can extract the bootloader and flash it, but this will not work!
You need to repartition your device to get the new bootloader to work. So you need to delete everything.
You can do it like this : http://forum.xda-developers.com/xperia-z2/help/tutorial-recovery-unlocked-bootloader-t3343416
I have snapdragon device( kenzo).. officially unlocked bootloader and installed cofface twrp.. currently on cm13.. want to revert back to global stable miui 8 , which is latest release... how to do that?? plz help..
1) flash akla twrp from ur present twrp
2) flash miui 8 global stable rom (1.19 gb)
3) reboot to fastboot mode
4) connect ur phone to pc and unlock the bootloader from mi unlock
5) reboot
Congrats, now you're in miui 8
There is no need to flash Alka twrp, cofface will be sufficient.
Also, no need to unlock the bootloader again if its already unlocked.
Just flash the correct version from here http://en.miui.com/a-234.html through cofface twrp.
Also, dont forget to nand back up your current ROM.
Flashing the mi recovery rom through alka twrp relocks the bootloader, and that's why the device can't boot into miui after flashing.
Unlocking the bootloader solves this problem.
Both the methods are legit.
Up to you which one you'll choose.
I am not sure if simply unlocking the bootloader again solves the problem. I tried that and Miui would still enter the boot loop even after unlocking.
Hi! I have officially unlocked my bootloader.
Can I just follow this steps(no more no less) to go back to Stock MIUI?
http://en.miui.com/a-234.html
i'm afraid because I read that it may cause a bootloop to Mi logo only
Hey all!
I just got my Note 3 (Snapdragon/Kenzo) from DX and it came with global US rom. I checked and its bootloader is already unlocked. I want to update to Miui 8 global dev but I'm worried with this unlock, is there a way to know if it was officialy or unnoficialy unlocked? I want to flash the oficial recovery rom but heard that it can brick the phone if it was unnoficialy unlocked.

It came with Miui 7.3 Stable (7.3.2.0.0 LHOCNDD)
Please, help. =)

That is a vendor rom.
More than likely it is unofficially unlocked, because your only allow to unlock 1 device per month for each account.
Since your bootloader is unlocked, flash an official rom (which might lock the bootloader again).
Don't flash the latest 6.0.1 rom yet as you might not be able unlock with that.
Then unlock officially.
Check the reddit xiaomi wiki for guides.
Got it! Thanks, for your answer. I realy dont mind unlocking, I just want a miui 8 dev(it has a built in root, right?). I just was afraid of what method of flashing I should use with this unnoficialy unlocked bootloader. I'm going to search this wiki for it.
And better do a Alka TWRP backup now, before anything! Then, if you get your bootloader locked, you can always restore the backup to your current status - ROM and unlocked bootloader. I have two Kenzos in the same situation, and that's the way I do it.
Nice! Will do. Can't I just use that recovery to install an updated rom? There is an annoying bug on this version, I can't open my contact or dialer app, they close befero they appear on screen, tried erasing data but no help.
Boot from TWRP without installing it, make the backup (all partitions), then make sure you get the backup on your PC. After that you can install TWRP and make whatever you wish.
And don't forget, if you need to restore, do it without restoring the firmware partition, or else you'll get an error.
Thansk! But I think I will stick with the global dev. Can I flash it via Fastboot (MiFlash)? This unnoficial unlock wont cause any trouble, right ?
This is not an unofficial unlock. Is isn't either official
My phones came with some vendor MIUI's - 7.4.9.0(LHOCNDD), respectively 7.4.18.0(LHOMIDD), but I never flashed another MIUI, just custom ROMs. For what I know, if you flash via fastboot it will wipe the entire partition structure, including boot and recovery, and the bootloader will get locked. In that case you can not restore the backup you make now. You'll have to apply for official unlocking, or go unofficial.

that means.. you recieved an unboxed device, may be refurbished, repacked and resealed and sold $25 costlier than the original. :silly:
Not necessarily. I have two, buyed from a local big online store, both came with unlocked bootloader. Both boxes were sealed, with no sign of foreign hands
I have 7.3.2.0.0 LHOCNDD rom and unlocked bootloader. Can I just type on fastboot:
fastboot flash recovery recoveryAlkaUpdate.img
to get twrp(alka)?
Thats work!

I have the same MIUI vendor as you, 7.4.9.0(LHOCNDD), what method did you use to install TWRP? I only want to install AOSP/CM based ROM on this device. I want to flash it ASAP cause this MIUI ROM have a Trojan downloader, which luckily can be disabled.
I used Cofface on first phone, Alka on the second. Before flashing, first boot from TWRP image, make backup of all partitions to the SD card, copy the backup on computer, and only after that flash the TWRP image. After that... flash ROMs

In Xiaomi you there isn't any TA partition so you don't have to worry about DRM keys. You can simply unlock bootloader and fastboot flash TWRP recovery and SuperSU binary via recovery to get root access.
I recommend you to unlock bootloader and flash zcx recovery and create a full nandroid backup before mounting system partition. This way you have a complete backup of the current state and you can return to it at any time.
You can install any custom ROM via recovery.
Unlocking bootloader won't void the warranty.
If you want to use marshmallow you can either flash beta MIUI ROM with/without unlocking bootloader or unlock the bootloader and flash a MM based ROM via recovery.
You can return to factory state at any time by either flashing MIUI fastboot ROM via EDL mode on locked/unlocked bootloader or by flashing fastboot ROM via fastboot mode on unlocked bootloader.

I won't recommend you to use kingroot to root the device due to following reasons:
1) I don't trust these shady chinese closed source apps that relies on software vulnerability.
2) If you've rooted by any method without unlocking bootloader you won't be able to flash "incremental" OTA updates as it verifies system partition before flashing. However, you should be able to flash MIUI full recovery ROM that'll overwrite the whole image without verifying for the changes. Unlike OTA it's usually about 1.2GB in size. There's another method to flash OTA without system image verification which involves removal of a few lines from updater-script but I haven't tested it yet on stock recovery.

1) If you want to revert back to MIUI from CyanogenMod, restore nandroid backup. But make sure to backup every partition in TWRP recovery first before any modification. And don't allow system modification on the first boot to recovery. Firstly, create a full backup and then you can flash whatever ROM you like. In case you want to switch back, restore the full backup except "firmware" partition. I suggest you to use zcx recovery. You can find more about it in the xda thread.
2) If you don't have a TWRP backup, you can revert to stock ROM by flashing MIUI fastboot ROM via pc in fastboot mode. You can do the same in EDL mode but it'll wipe everything including internal storage.
3) If you want to install MIUI beta ROM based on MM, you can do that both on a locked and unlocked bootloader. Go to en.miui.com and download the latest beta ROM, put it on your internal storage and use the updater app to install it.
4) If you do the step (3) and want to revert back to MIUI stable based on LP, then you'll face sim detection issue which can be fixed by flashing modem (NON-HLOS.bin) of the same stable ROM via fastboot on unlocked bootloader. This is a bug from Xiaomi side.
5) You can use MIUI beta ROM, actually it's more stable than MIUI stable ROM and most people prefer it over stable.
Hope that helps
