Can i install twrp with locked bootloader with eng rom installed?
No. You can't.
Because you need to disable verification on vbmeta and this requires unlocked bootloader.

Yes.
You can write the imei for the slot2 and keep the imei for slot1 as null/empty.
It will works perfectly on stock MIUI and then you can unlock bootloader using the SIM on slot2.
I have that problem now
Can you help me bro?

Thanks for your reply
I tried to flash many roms with flashtool but nothing change.
You lost network coverage but does it still offer to unlock the sim? And does that succeed?
And just to be sure, you did flash the correct stock ROM your model (C5302/C5303/C5306)?
If your bootloader magically relocked itself then sony pc companion should work (I know it sucks), have you tried repairing your firmware using that?

But if your bootloader is unlocked then the bootloader status should say "Bootloader Unlocked: Yes" or something along those lines.

That is so unusual that you might want to check with fastboot if the bootloader really is locked. You can do that with the following fastboot command:
Code:
fastboot getvar secure
This will return "secure: yes" if the bootloader is really locked.
Anyway, have you tried a generic ROM for your device from this thread? http://forum.xda-developers.com/showthread.php?t=2311964
If you have a north american device (C5306) you might need a provider specific ROM.

That wont work...
Go to terminal in root mode and do
Code:
Setprop sys.oem_unlock_allowed 1
Than you can change the value and its not longer greyed out.

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

I haven't gone that far. I've unlocked and then relocked.
Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.

That's too bad. Means we won't get back our waranty if we relock it ?. So thanks for the heads up . I'll be careful while unlocking it again (if ever).?

Not necessarily, I doubt if most service centres would bother delving that deep, but maybe some would.

No, but I haven't delved that deeply into Huaweis bootloaders, but I NEVER attempt to re-lock them.

I am on MIUI 12.5.1.0.RJOINXM. My bootloader is locked. I don't have prior experience in flashing roms. Please help me to downgrade to MIUI 12.0.8. Thank you
No way. You must unlock bootloader then flash the older version with official Mi flash tool.
You can downgrade to any version using spflashtool easily, securely and safely.

Oh, okay.
If you flash in DOWNLOAD MODE, bootloader will keeps SAME, locked or unlocked.
If you flash in FIRMWARE UPGRADE MODE, bootloader will be LOCKED again.
If you flash in FORMAT ALL MODE, bootloader will be LOCKED again and you will lose all identications of the device like IMEI, BLUETOOTH MAC, WIFI MAC.
You can downgrade MIUI safely and securely using download mode.
Thank you, but what is DOWNLOAD MODE?

Dear VD171, i've just downgraded using MiFlashToolV2. The process was simple and the bootloader is still unlocked, so far so good.
But now it refuses to boot to system. It keeps restarting and shows the initial "Redmi", with the unlocked icon in the top.
I tried to Wipe data in xiamoi recovery, but the result is the same.
Please advice

Problem solved by using official xiaomi flash tool, thanks
Hello. I wanted to root my redmi note 10s, and I unlocked the bootloader. But after reflexion, i want to cancel it, cause root will not be useful as I thought. Is it possible to relock the bootloader? And if yes, will the process erase all data ? And will everything be back like before? For example, will I be allowed to use Google One, witch doesn't work on bootloader unlocked devices ? Thanks by advance

yes, relocking the bootloader will erase all your data, to do so just use miflash and select the option clean flash and lock

Yeah the title says it all. Just wondering if that's possible or not since I'm not sure if I'd have to wait for a week for my phone to be unlocked, while I could get the job done in no time.
If unlocking the bootloader is required, then would force unlocking it using mtkclient work (triggers bootloop, haven't tried to relock it and see if it fixes it)? Or will it only work through official bootloader unlocking?
No, you need to unlock the bootloader in order to flash a recovery over the stock one

You need to unlock first, since locked bootloader will block any flash over system partitions
