[Solved] Any way to unlock FRP after OTA update? (P10 Lite)

Hello!
I recently rooted my new P10 Lite before version B124 was released, but then I decided to update my phone from B102 to B124 by flashing the recovery image from the Update file and then updating via OTA with the full update files.. The phone updated successfully but yesterday I used adb to boot into the bootloader in order to flash TWRP but noticed that FRP is now locked and i cannot flash TWRP without getting command not allowed error.
I also tried unlocking the bootloader (just in case it was locked for some reason) using the password i got from huawei but even that gives me an error. The enable OEM option in developer settings is greyed out since after the update and is till greyed out even after clearing cache and factory resetting the device. Now is there a way for me to unlock FRP again in order to flash TWRP? Or maybe another way to flash TWRP. Hopefully someone knows a way.

Use DC Unlocker.
I used it to unlock my bootloader on P9. Works perfectly.
They do FRP unlock and supports P10 Lite.
Costs 15 credits so 15 Euro.

Thanks bro. Wish i saw it before spending 15 credits in DC unlocker. Even after removing frp i am still not able to tick enable OEM unlock in developer settimgs or flash twrp in fastboot. Only thing on my mind right now is to lock bootloader and see if enable oem unlock option will be available after that.

P10 Oreo and root

I recently updated my P10 VTR L29 C432 from nougat to Oreo B360 via oreoupgrade script method as posted in forum but after update my bootloader seems to be locked again i wanted to root my phone via installing TWRP but it's not allowed by fastboot
Any solution or any solution to unlock bootloader without losing data !? I have too much files and apps on phone that i won't lose

I still have the same problem, created an thread many weeks ago and still don't have an reply. Seems like the only way is to make an backup with that backup tool in the settings (advanced->save&restore) or an backup with hisuite...

There's no way to unlock the bootloader without factory reset.
You can only do a backup with HiSuite or Huawei cloud - but notice: you need to backup DCIM manually!
Just a question, because you said, that you updated your phone with my oreoupgrade script:
Did you follow my guide exactly or did you do anything after the update progress was finished?
I need this information, because if this happens to more people, I need to take a look on the progress.

That's odd. All devices I testeds stayed unlocked after update.
The update won't lock the bootloader by itself - normally.
You're sure, that you didn't lock it manually?
Is only the FRP Lock active? You can unlock this by enabling the OEM Unlock in Developer Settings in the settings app.

Okay, that's bad. I'm sorry for this.
You need to unlock it with fastboot command and do a factory reset.
But don't know why the update process locked your phone while other stay unlocked.

Yeah, yeah, flash a twrp recovery, use the integrated option for magisk install and install magisk app. In the EMUI 8 custom ROMs, there's SuperSu integrated. But I once I got frp lock when flashed magisk...

Thats wierd if it gave you the frp lock, you can just remove that lock by going into dev settings -> allow oem unlocking.

I wasn't able to use this option. Maybe it's because of the custom ROM because I still use one and I can't use the oem unlock option, tough my frp is unlocked. But watch out.

It should be enabled, what is your rom?

It happened on Elemental 1.1 by KingOfMezi first, now I use Morfus by Catuva, because of some bugs in Elemental before the today's fix. I was in Nougat, because I bricked my phone with that frp lock and the option was available. Now it's unavailable once again. I didn't check when I was on official EMUI 8, but it was probably available I think.

If you really want to get frp removed you can check out dc unlocker... or dc phoenix to flash the full stock rom

I don't need it for now, I just said it like by the way, just watch out for frp lock and careful if you get it, especially if using custom ROM.

If you have unlocked bootloader oem option in developer is grey and inactive. So if u screw something with magisk and deacrivate oem it means frp goes locked its very hard to activate oem and get frp unlocked again especially on Emui 8. In this case u must use DC unlocker, it means credits, or
You can use frp unlock.zip to flash via Twrp in order to enable oem and frp.
Zip file you can find on

Or you can just get a custom rom installed that will be able to enable frp unlock and then just go back to emui 8

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.

Relock bootloader VOG-L29

Hello
I purchased the device of the title already unlocked and would like to return it to stock rom and lock the bootloader but I don't have the unlock code. I followed a guide found here using an otg cable and a pendrive to return to stock in hopes that it would also lock my bootloader but it did not. The procedure completed successfully twice, 1st going from .178 to .185 and second attempt from .185 back to .178. Every time the phone was factory reset but the bootloader remained unlocked. Any ideas on how to relock the bootloader on this thing without having the unlock code?

That's very strange, service firmware always lock bootloader but in your case it can't. Anyway I have two suggestions for you first go to developer option and uncheck OEM Unlock option then try dload.
Second is try this method Thread Link Click here. Third and last use erecovery for stock firmware restore.
Hope this will help you.

Hi did you tried above methods? What's the result? If not try TWRP tool which I've suggested you.

I personally advise don't lock bootloader, if you don't know code ask your seller for it.

Hi. I'm in the same situation. I have a Huawei P30 Pro that came with an unlocked bootloader. The yellow message at startup is really disturbing. I would like to relork the bootloader but in vain. The fastboot oem relock command does not work. I flashed the firmware in ota and also by erecovery but nothing works. Recently I noticed on the back of the phone the inscription NOT FOR SALE. I don't know if it has anything to do with it or not.

Hi guys,
Sorry for this stupid question but how do you check your bootloader status on this device?

fastboot oem relock command need oem bootloader code.
you can try with full ota upgrade via OTG via Dload metod. long press the volume up key + volume down key + power button.
Choose the right firmware ,same country of your PHone (example europe C432).
But you are very lucky to have an P30 pro unlocked...don't relock.....
