if you are talking about twrp asking for your password you pretty much need to do the entire tutorial again except for root as you should be still rooted the nocheck recovery replaces twrp and allows the update.zip to be ran by emui updater you can then flash twrp again but twrp has issues with decrypting data there is an unoffcial twrp but i don't think it works with pie but that version has decryption support you can get that version https://xdaforums.com/huawei-p20-pro/development/recovery-twrp-3-2-1-0-t3779400 but as i side im almost certain pie brakes it

No check its current not need u can flash anyting using erecovery and flash firmware... Or using funky before only need oem unlock for u wanted region and twrp can flash anyting for oreo correctly only emui9 have issues flashing on huru... Roted u can flash anything using flashyfy tool

No check is ussuless
[Huawei P20 Pro Guides, News, & Discussion] nubston:
no check is required erecovery will only use wifi and download the most current firmware that fits if you are following this guide you require the nocheck recovery please don't spread misinformation as you are risking people following this guide and bricking there device

the nocheck recovery you uploaded is just twrp and trying to debrand/rebrand with twrp is almost guaranteed brick and people don't want to use funky for rebranding because it brakes bootloader unlock codes as it messes with your serial numbers

THIS GUIDE REQUIRES THE NO CHECK RECOVERY I LINKED PREVIOUSLY PLEASE USE THAT

Where did you get all the files for mate?

I'll upload them to my mega and maybe keep them up to date.

---------- Post added at 03:37 AM ---------- Previous post was at 03:34 AM ----------

It was written when pie was not released, it worked at the time.

If you're still on Oreo it will still work.

I haven't claimed it's for pie.

If you have a way to get the same job done on pie, please be my guest and write a guide.

Sorry guys i close the files... My p20 pro die.. Please be carefull on ur phone... My phone bricks on try some of this process send to rma... I have luck and huawei exchange for mate 20 for free... But is pure luck...
[Huawei P20 Pro Guides, News, & Discussion] Sleipnirr:
Let me tell my experience:

I had CLT-AL00 181 which is pie. After unlocking bootloader I downgrade it to 176 which is oreo using this topic. It gave some errors, went recovery or erecovery I don't know it made something, It finally it opened but version number was chipset-boston. Then I followed post #152 on this post for rebrand and it totally worked. Finally my version was CLT-L29 161. It was working very well but I decided to update it to pie which I understood I should NEVER try. I use EMUIFlasher_1.0.apk to upgrade and it gave error during process. Now my phone don't turn on. No screen, no vibration, nothing. But when I connect it to PC, It says it is in fastboot. So I think I have some chance to recover it. I tried fastboot commands to unbrick they seems they are working but nothing changed. Then I buy Type C - USB adapter to try Dload method but I couldn't sure I put it download mode because I couldn't see anything. I think there is also another chance to unbrick it. "Test point" method. I will try it when I disassembly my phone.

Last status:

[IMG="Last Status"]https://ibb.co/9vtw3My[/IMG]

Edit: I may find something causing error:

"fastboot oem get-build-number" command replies: (bootloader) :CLT-L29 8.1.0.161(C432)

"fastboot oem oeminforead-SYSTEM_VERSION" command replies: (bootloader) :CLT-AL00 9.0.0.167(C00E55R1P15)

So I think I should downgrade system version "fastboot flash system system.img" seems working but version number doesn't change.
[Huawei P20 Pro Guides, News, & Discussion] dlads:
Not too sure, if you can get fastboot running via your pc then that is your best bet.

I've read about flashing the different components one at a time, there's a recovery thread here somewhere, take a look and see.

One thing I would say is to read before you commit. Make sure someone else in the same position has done it before.

Thanks to [MENTION=7530018]oslo83[/MENTION] My phone is alive again, rebranded from CLT-AL00 to CLT-L29, working android 9 and receiving OTA updates. We use test point method to recover my phone.

I found where I made mistake and bricked my phone:

I use EMUIFlasher_1.0.apk to update Oreo (161) to Pie after rebrand. I choose CLT-LGRP2-OVS 9.0.0.247 to update but It was very big mistake. This file was Pie to Pie update which I learned later. After we recovered and came Oreo (161) again, this time I used "Huawei P20 Pro CLT-L29 CLT-L09 hw eu HLRCF Charlotte-L29C 9.0.0.195(C432E5R1P9T8)" to update Pie and everything go back to normal.
[Huawei P20 Pro Guides, News, & Discussion] colinlovesc:
Hi, NEWBIE needs HELP.

I got a China version CLT-AL00 from a friend as a gift which has been updated to PIE.

Luckily the bootloader unlocked service alive again. The Bootloader is been unlocked.

I follow the Sleipnirr’s experience to downgrade to 176. Going over OP and #152 again and again. Trying to download all the necessary files since OP’s google drive link dead already including 8.1.0.161(C432) files and Huawei P20 Pro CLT-L29 CLT-L09 hw eu HLRCF Charlotte-L29C 9.0.0.195(C432E5R1P9T8 .

After I root the phone with ramdisk-CLT-L29-MAGISK.img fastboot flash ramdisk CLT-L29-MAGISK.img and then flash and fastboot flash recovery_ramdisk recovery_ramdisk_nocheckP20.img, I installed the Magisk Manager. I got the unsupported Magisk Version. Is there any step I’m doing wrong? ( I didn’t install the TWRP, just unlocked phone, flash ramdisk CLT-L29-MAGISK.img then flash recovery_ramdisk_nocheckP20.img )

I seem to recall a particular update that caused this.

The later updates changed it back. What firmware are you on

[Huawei P20 Pro Guides, News, & Discussion] dlads:
No what I meant was I've seen this symptom where previously unlocked bootloaders and non greyed out OEM sections have suddenly changed due to an update, apparently it was one of the pie ones.

I've personally avoided pie, there is no reason to make the switch imho, the ROMs are better on Oreo and with the p20 pro, there is at least half a twrp working.

I'll be buying the OnePlus 7 on launch so will be saying good riddance forever to Huawei, they've seen my first and last purchase.

If I were you I would create a thread and search the p20 pro, p20, p20 lite, Honor view 10 threads for a suggestions.

Personally I think a future update will fix it.

By all accounts this can be done with a little tweaking, but be careful

Hi Guys,

Forgive my (possibly) dumb questions... BUT.... here goes...

I have had my P20 Pro on O2 UK for about 8 months. I believe it has some form of customisation from O2 as i have no settings to allow me to activate WiFi calling (perhaps because O2 dont support WiFi calling on this handset.

I have recently unlatched the handset from O2's Network and want to use a SIM from a network that DOES support WiFi Calling.

Are there any particular tricks that I need to do to my handset to "activate" the wifi-calling option in settings? Perhaps I need to flash a stock firmware or change a retailler code or something?

Help appreciated!

I rebranded from a UK L09 to a euro L29 some time ago. I have just tried a sim from a different provider and its not working. I checked again with the

Original provider who said its been unlocked from day one so never provided a unlock code. They got that from huawei

1. Is it possible that the rebrand had screwed this up?

2. Has anyone rebranded and used other network sims ?

3.is it possible to rebrand back to original UK L09 to see if that cures the issue?

4. Any suggestions to resolve this?

Thanks
[Huawei P20 Pro Guides, News, & Discussion] happyhammer66:
im trying to go back to L09 C782 UK version after rebranding it to L29 C432. not getting every step correct in the partr of the debrand guide but whilst rooted when i try the oeminfo command i get an error

1|HWCLT:/data/local/tmp #

1|HWCLT:/data/local/tmp #

1|HWCLT:/data/local/tmp # ./oeminfo CLT-L09 C782 hw/eu

./oeminfo[1]: syntax error: unexpected ')'

1|HWCLT:/data/local/tmp #

1|HWCLT:/data/local/tmp #

any idea why i get this syntax error?

i was thinking of using the OTG service software which i used before for L29 but it has L09 folder as well., thats at 9.1.0.311 but i assume this dont change the oeminfo so thats why i want to change the model back to L09 C782. another command i might try if i get L09 C782 oeminfo file is

dd if=/data/media/0/oeminfo.img of=/dev/block/bootdevice/by-name/oeminfo

so any help appreciated
[Huawei P20 Pro Guides, News, & Discussion] happyhammer66:
Well I used hisuite to rollback to 8.0 and then the new sim was seen. Went back to 9.0 and not recognised again. Tried changing to L09 by using an oeminfo twrp backup from L09 C432. This changed it to an L09 ok but ballsed up the bootloader unlock code so it's no longer re cognised. That's the end of it for me i think. Never again an Huawei,
[Huawei P20 Pro Guides, News, & Discussion] vectorsum:
HUGE thanks to OP for making this guide, I was able to go from CLT-AL00 9.1 to L29 9.1 using this method. Initially misread some instructions and bricked my phone pretty hard (to the point where Erecovery did not work). Thanks as well as Vedrick from this thread for steps to recover and get back to a working state to re-do the procedure from OP.

Some notes which hopefully are helpful to anyone else in this situation:

One thing which was key was that I had to flash some partitions which were not usually flashed through bootloader.

Additionally, because i was softbricked, to do OP's procedure I had to

1. flash TWRP in order to

a. run ADB, transfer update/update_all_hw files, move to /data/update/HWOTA

b. run oeminfo, modify region code

c. echo the update commands to /cache/recovery/command

2. reboot to bootloader in order to flash the recovery_ramdisk_nocheckP20.img

3. finally reboot to patched recovery for update to happen.

Definitely do NOT recommend following what I did unless absolutely necessary.
[Huawei P20 Pro Guides, News, & Discussion] happyhammer66:
So after screwing things up, turns out it was just the phone not recognising the new sims when the sim lock code was active. Once i disabled that, it recognise the sim immediately. So just a stock phone from now on but given the lack of custom ROM , no big deal. Its still a good phone user wise

Hi, Many thanks for your help.

I do these steps all over again, exactly the same?

I need to do root again to be able to do step 10. So step two is also necessary right?

step 6 and 16 is not necessary, right?

2.Root your P20PRO with Patched Ramdisk ramdisk-CLT-L29-MAGISK.img

3.Copy firmware files via MTP to your internal memory

update.zip

update_all_hw.zip

update_data_public.zip

4.Boot into fastboot mode and flash no check recovery recovery_ramdisk_nocheckP20.img

fastboot flash recovery_ramdisk recovery_ramdisk_nocheckP20.img

5.Install Magisk Manager MagiskManager.apk

6. Copy OEM info binary file to internal memory oeminfo.bin - NOT NECESSARY?

7.Boot into Android System enable adb debbuging in developer settings.

8. Start ADB

9.adb shell

10.su

11.accept the prompt at your P20pro

12.mkdir /data/local/tmp

13.mv /sdcard/oeminfo /data/local/tmp NOT NECESSARY?

14.cd /data/local/tmp

15.chmod +x oeminfo NOT NECESSARY?

16. ./oeminfo CLT-L29 C432 hw/eu NOT NECESSARY?

17. mkdir /data/update/HWOTA

18. cd /sdcard/

19.mv *.zip /data/update/HWOTA

20.Paste recovery command:

echo "--update_package=/data/update/HWOTA/update.zip" > /cache/recovery/command

echo "--update_package=/data/update/HWOTA/update_data_public.zip" >> /cache/recovery/command

echo "--update_package=/data/update/HWOTA/update_all_hw.zip" >> /cache/recovery/command

21. Exit

22. Exit

23.adb reboot recovery

24.Phone will reboot and starts to install and Rebrand your Phone

Tried before, no hope in this way. Fastboot mode shows me oem locked now but fastboot command tells me "oem unlocked"; I can still not excute "fastboot oem unlock", because it tells me "please unlock FRP first". Tried "fastboot oem frp-unlock" , it needs another passcode.

Now excuting other fastboot commands seems to be ok, except this one:
