Re-lock Bootloader

I have the XT-1052 version of Moto X and its running the Asia Retail firmware. I had unlocked the bootloader and flashed CM12 but returned to stock rom through this guide http://forum.xda-developers.com/moto-x/general/retail-firmware-uploaded-xt1052-t2976596. I will be selling the device and want to re lock the bootloader. Can i type the ''fastboot oem lock'' command in mfastboot tool and re lock the bootloader? Also, will it erase the whole data on the device?

Yes, fastboot oem lock will lock it, and no it will not wipe data. Only unlocking wipes data.

But you status code will show relocked you can never get status code back to locked once unlocked.

Correct. Whoever has the phone will be able to see the "tamper seal" that shows the bootloader was previously unlocked, but is now locked again.
I would provide whoever you sell the phone to the bootloader unlock code so they can unlock in the future if they so desire. Not sure if they can request the code from Motorola again or not.

I tried it but it asks me to flash the signed images. The link i mentioned above comes with an XML file which dictates the steps RSD should be following, right? So if i upload the XML file can you edit the command line and add the command? I am not an expert in this stuff.

i have relocked flashing manually with fastboot, not sure if you add the oem lock cmd to the xml will work.
fastboot oem lock begin
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash logo logo.bin
fastboot erase userdata
fastboot erase cache
fastboot oem lock

The files that are present in the rom folder are boot.img, fsg.mbn, gpt.bin, logo.bin, motoboot.img, NON-HLOS.bin, recovery.img and system.img. Can you modify the list of commands to add the aditional files. Thanks.

just flashing the above is enough to relock. Flash away

Relock Bootloader

Hello,
Im trying to relock my bootloader again, did i just have to use the "fastboot oem lock" command? Because i read it somewhere that i have to flash stock rom before locking the bootloader, if yes can someone give me the link for stock rom and how to flash it, FYI when unlocking im only using "fastboot oem unlock' command, not doing "fastboot unlock critical blablabla".
Any help would be appreciated, thank you

as far as i know, you need to flash stock bootloader of your current android build then uninstall magisk (if you have it) and just use fastboot oem unlock and you're done (note! backup all your data cause it will make a full wipe)

I stopped after unlock bootloader only, i didnt root it at all, so you mean after flash just run fastboot oem lock command?

Then you don't need to flash anything at all. Just run fastboot oem lock command.

Exactly, you don't need to flash anything. Just put phone into fastboot and run fastboot oem lock

Will it wipe data again just like unlocking?

Yes. It will wipe your data. Please becareful.
Oh. Please sure that you have back to original boot image before relock or your device will brick.

I never relock bootloader .. what I know is you must have fully stock ROM installed then only advisable to lock bootloader. Never do on rooted stock & custom ROM.
Maybe someone else can advise you better.

Did you lose data after relocking? I mean lock bootloader causes a data wipe like unlocking?

"Fastboot oem lock" seems to be depreciated for Mi A2, better use "fastboot flashing lock" instead of "OEM unlock" (though probably these are still equivalent).
And yes, full unlock is achieved when after general unlock you are unlocking critical (once more approve on phone, once more user data erased).

For your information. I've just bricked my Redmi 10S with stock ROM with the command ""Fastboot oem lock" :-(

Help bricked mi a2

I was trying to install stock rom after installing RR rom. MiFlash said "flashing is not allowed for critical partitions" and when i did "fastboot flashing unlock_critical" from cmd i got "remote: Flashing Unlock is not allowed". I then used the allinone tool from xda and pressed "lock loader" to unlock it again and ended up bricking the device as it now shows "your device is corrupt. it can't e trusted and will not boot" I can't enter recovery either only fastoot and nothing works. PLEASE HELP FAST

Dude, how many threads do you need to create, it won't make it any more likely that anyone will help you
Your problem is caused by that you only unlocked the bootloader and not critical partitions
Which stock rom were you on before flashing a custom one?

Are you sure?, if so, manually flash boot, system and vendor using fastboot to your current slot
Fastboot flash boot_a boot.img
Or boot_b if active slot is B etc...
Then go to developer options and enable oem unlocking, if you can't enable that option, lock the bootloader, enable the option then unlock bootloader and critical flashing

Few days before I was in the same situation.
Tried lot of solution but the simplest to solve was using the below 2 command when in fastboot.
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flashing unlock
This should unlock the bootloader and you should be able continue the setup.
All the Best...

Here is the link to download required file by an XDA member.
But before you flash system image first try with the boot img and recovery img.
I was to getting the message that i cant flash so used the command for oem unlock which reset the counter to 1
After which did flashing of boot .img and then recovery.img
If issue the use the falshboot flashing unlock.
This were the steps used by me to recovery, i didnot do any other flashing.
Hope this helps you
Edit: After the oem unlock command directly try to flash boot and then recovery and then if required flashing unlock command.

its still saying your device is corrupt ...anyone can help me

Then type this

if you do fastboot oem lock, it locks both (flash_all_lock does that)
