There are some tools here in XDA to do that. Try to find in P20 pro thread.

Yes. After rebrand my phone in dual-sim I recived two OTA update. Now I'm in 8.1.0.128(C432). Last OTA of 537MB made about 3 days ago.

you don't need to lock your BL if you want to receive OTA ! anyway if you lock it you will be not able to unlock it again! my BL is unlocked and OTA update work perfect ! last OTA for L29 is 128 firmware but not 128a !

I understand. I replay to your answer.
I said you to look here ==> https://forum.xda-developers.com/huawei-p20-pro/development/tool-tool-one-driversunlocktwrpfactory-t3779416
Or use FunkyHuawei tools.

Do you have a stock recovery or a TWRP? As I've read somewhere on the forum you have to be on the stock recovery to flash OTAs. But let someone confirm this cause I don't have the P20 PRO yet.

Without the unlock code you cannot relock.

Is it simple enough to do? And did you relock the bootloader when it was complete?

Yes, it's pretty simple. I made it because I wanted to transform my P20 pro single sim to dual sim and it worked !
After procedure the new bootloader become re-locked. You can't use anymore the Huawei code to unlock boootloader and you can't root the phone or install twrp.
Until Funky find a system to unlock without code.

I had heard that using any of Funky's procedures relocks the bootloader and the Huawei bootloader unlock code no longer works. But like a lot of people, I purchased my unlock code from a 3rd party. So it would be interesting to see if it survived a Funky method.

I didn't know that we can buy unlock codes.
But surely your code do not work after procedure!
Because Funky firmware chanche your bootloader code. And so unlock codes doesn't work anymore.

Yes there are a few sites offering bootlocker unlock codes. https://ministryofsolutions.com/huaw...-new-firmwares does them for 30€, although they only accept so many paypal payments per day. https://global-unlocking-solutions-...es,_Choose_Model_Below/p5093122_19186756.aspx is €35 but has no limitations on paypal payments. I believe that both are totally legit, according to P20 onwers here.
Funky Huawei is a strange one. If you use one of their options to, say, change your region, model number etc, it will lock your phone again and make your current bootloader password useless. And the bad thing about this is, they don't offer an unlock service. Unless you pay for their unlimited use pass, which costs $132. Then they throw in a free bootloader unlock. I'm not sure if the relock and code breaking is a deliberate act by Funky Huawei but personally speaking, they should be giving a new working code to anyone whose unlock code they've trashed.

Manual update P10?

Anyone succeed with manually updating P10? I have tried with no sucess.
Old method is not working.
Thanks
No but did you made the dload folder with the update.app file and then booted into the stock recovery mode?
I woudnt know any other way since they removed that from update settings : |
I tried that, does not work.
You can't manual update the P10 or P10 Plus, since it requires an online check.
They removed the ability to manual update via dload methode.
The only way at this moment is to use FunkyHuawei!

What about Firmware finder? I've tried this as well but I only get download failed, even everything is done as it should.
Hey,
I am working into this direction and got some promising results already. I am testing two more things during the next days (so that I can be sure my Stuff won't break your phones) and hope I can share my findings with you early next week.

Good to hear that. :good:
So, it is not possible to update, even the firmware matches your corrent model/brand?
I finally found the FW for VTR-L09C109, but when using dload method I get "Installation failed".
No, it is not possible. Huawei did something with emui 5.1.

Not always correct. It depends on the local country laws you live in.
And also if you follow the instructions you end with LOCKED Bootloader so no warranty lost

Is it same with P10 as it was with P9, tha it say relocked instead locked bootloader, when you lock it again?
nope : Phone LOCKED
FRP unlocked so they cant see the difference they can only find out if they check if you got the bootloader unlock code.but you also could request the code and dont use it.
Any progress here? The update has been out for months in other regions but I still haven't got anything here in Sweden :/

Whats the method to root / unlock bootloader of this device now? how?

Look at DC Unlocker, but note that this will cost you a few €.
no other way to root the device or get the unlock code? Will emailing them help? I kinda have to root my phone to recover some lost files. I dont have a lot of options. Can someone please help?
Huawei won't send you the unlock code via email, you can try it but there's not a great chance.
Only easy way is DC Phoenix, as @M1chiel already said. It's a tool made and serviced by Huawei, which is just a flaw against their users.
If you got your unlock code and unlock your phone it will do a factory reset, so all user data will be removed.
And there's absolutely no way to avoid this.
But if I'm allowed to ask, what do you want to recover? Everything you can do without root is stored in /data. If you deleted files you can try to recovery the files with apps without root.
But the recovery chances are low because with electronic based memory removed data is mostly totally gone.
You can buy code from Funky Huawei for 55$
Only 4€ with DC Phoenix and works for sure

hi,
I tried but guys from DC support said that maybe some security patches are blocking reading phone.
I tried to get DC Unlocker working but it doesn;t read my bootloader code. The DC Unloacker gave back my money right after they saw print screens from my 10 dual with 361 firmware from my operator. I wanted to debrand it to official but still frustrated not being able to do it.

Got it worked. First flashed Nougat with FF app then unlocked with DC

i think yes, detecting is free but actions to perform are paid by credits
i had similar and two more errors - helped to switch to different usb port to install fresh set of drivers - that includes those ones when you switch to manufacturer mode which is needed for dc-unlocker to work correctly

Huawei Mate Pro 20 Lite

I currently own SNE-LX1 on Android Pie 9.0 with 9.1.0.229 (C432E4R1P1) Build.
Just wondering if anyone flashed TWRP succesfully onthis version?

I have an option for OEM unlocking though. Haven't tried it since it'll format everything.

You need an unlock code from Huawei to unlock the bootloader, but since more than a year ago, Huawei doesn't provide unlock codes anymore
Huawei have stopped giving away the bootloader unlock codes, and most of the "3rd party" websites don't actualy provide this - those that promise the code are mostly fake and you should avoid giving them money (unless you like to giveaway money to scammers)
Anyway, even with the unlocked bootloader, you still don't have a TWRP port for the most recent updates of the Mate 20 Lite....

(Q) Query about bootloader and re-packaging an OTA

hi all,
Just having a thought (might not work but thought i'd ask)
Some OTA's / Firmwares which you can install from the bootloader have the ability to re-lock the device, would the same be possible for the other way around?
I mean i'm on a locked bootloader now cos of the crap i installed which updated me to 9.1, it relocked the bootloader, I can turn on OEM unlocking (FRP) but obviously it remains unlocked.
Would there be a way to repackage a firmware package so that it does the opposite to re-locking?
I think everyone has pretty much given up on Huawei devices, I was just trying to disable zRAM and i can't.
Any thoughts ? Is this a possible avenue? or is this simply not going to work?
I'd guess the latter but thought i'd ask.
Which firmware version relocked your bootloader? I can perhaps take a look at it in my free time.

Nope! DLOAD re-lock bootloader to factory condition, but there's no way to unlock the bootloader with it.
I don't think Huawei will give you the unlock code a second time, but maybe you will be lucky, who knows.
Maybe you can retrieve it from an email from them!?
Edit: You can download your HuaweiID data from Settings - > HuaweiID - > Privacy Center but i doubt you will get the bootloader code from there

I've spoke with them, they said they've not heard of a situation like this.
Bare in mind that this is information that has been passed to me before. Which is a correspondence, they are obligated to provide it regardless.
I don't believe it was in an email and I've checked all accounts

yeah but then probably huawei was giving the bootloader codes and now they aren't and it is very unlikely to get it. And you need to unlock bootloader if you want to root your phone.
