[HELP] OEM Unlock option greyed-out - Huawei P20 Pro Guides, News, & Discussion

Hi,
I have a P20 PRO i bought online - with Unlocked bootloader and FRP locked.
The "Enable OEM unlock" option is disabled and greyed-out.
My ROM version: 9.0.0.108.
Eventually, I would like to root my device and have this ROM version flashed on it (9.0.0.195):

http://update.hicloud.com:8180/TDS/...l/CLT-L29_hw_eu/update_full_CLT-L29_hw_eu.zip
I don't have the bootloader unlock code (Phone is unlocked, but i don't have the code beause i didn't get it from the seller).
Would appriciate any help to fix this situation.
Thanks!

And your bootloader is unlocked, so isn't it normal that the oem is greyd out, till it is relocked?
Sorry for my bad english

I think it's a problem with the version and if i upgrade (maybe via OTG?) to a newer version it might solve the problem?
according to this: https://forum.xda-developers.com/showpost.php?p=78552410&postcount=2
But. if i upgrade to newer verson, i might lose my unlocked BL?

If your bootloader is unlocked, the OEM unlock option is greyed until you relock the bootloader.
Yes, the phone will automatically relock/lock the bootloader if you update your phone

Updating problem

Hi
my phone was rooted a month ago. i really wasn't cool with it, so i flashed the stock recovery and turned the phone into relocked state.
now i wanna install the update my phone received. but when i press install, it goes to fastboot screen with title of "security update" and nothing happens.
What should i do ?
Same issue

hi. i finally found a compatible recovery img. but i have another problem. as i mentioned before, i locked bootloader myself again right after flashing a stock rom (which i guess wasn't compatible with my phone). now when i try to flash the stock rom, it says i have to unlock bootloader. when i try too unlock it and press the final button, it goes to a page with title of "entering recovery" and i get stock there forever. so i just get my phone restart and come back to life. do u have any idea why it stocks there ? how to solve it ?
tnx
ok guys ... now i faced a very bad problem
i flashed the recovery file. everything was good. then i tried updating software from "about phone" section. update was going well. then phone tried to boot... now it's frozen at htc logo screen.... what should i do ?
no one is awake right now ? seriously ?

Is it locked by your SIM Card?

Revert OnePlus 7 Pro to locked bootloader and unroot?

Hey ive found a bunch of very helpful guides regarding unlocking the bootlader and rooting the phone. Is there any guide that assists in reverting the phone back a locked bootloader or unrooted state?
This would be very helpful for sending the phone out for repair/return.
This process worked for me when I got the sim unlocked: https://youtu.be/R4kh3gS2S3w

Just make sure you don't lock the bootloader while you're rooted.

This is correct. Back to stock and I'm able to download HD video in YouTube when the best I could while rooted was 720p.

Huawei will allow the Mate 30 Mate 30 Pro bootloader to be unlocked.

That's fine. But so far, Huawei said they shut down the bootloader for the safety of the customer. Find the mistake...[emoji38]
