Hi, Please help me, My P20 PRO CLT-L29 is bricked during re-branding. FRP is locked and boot-loader is re-locked. I am stucked at recovery. Factory reset from recovery finishes successfully but still the device doesn't boot up. E-recovery shows "gettting package info failed." Tried DNS e-recovery method through firmware finder but the DNS is not working!

Is there any way to unbrick my device?


fastboot oem get-product-model
(bootloader) CLT-L29

C:\Minimal ADB and Fastboot>fastboot oem get-build-number
(bootloader) :CLT-L29 8.1.0.160(C432)

C:\Minimal ADB and Fastboot>fastboot getvar vendorcountry
vendorcountry: hw/eu

C:\Minimal ADB and Fastboot>fastboot getvar rescue_enter_recovery
getvar:rescue_enter_recovery FAILED (remote: FAIL:need all image flashed!)

C:\Minimal ADB and Fastboot>fastboot oem oeminforead-SYSTEM_VERSION
(bootloader) :CLT-L29 8.1.0.154(C185)

FINALLY SOLVED by flashing the firmware files through dload method via USB- OTG. You can search and download firmware files on https://androidhost.ru/search.html

Feel free to ask if you face any difficulties.

How did you flash firmware via usb otg? Could You please link tutorial?

I didn't find any guide. I was in fact guided by Mr. oslo83 in a telegram group https://t.me/flashing_huawei

The process is very simple. I will try to reproduce the steps I followed as under :-

1) Download the correct firmware for your device according to your region from https://androidhost.ru/search.html and extract it. (Note :The downloaded firmware must be of the same build number installed or superior bcoz downgrading can hard brick your device)

2) After extraction you will find a folder named "dload" (This is our concerned folder, pay attention!)

3) Inside the 'dload' you will find one zip file named 'update_sd', extract its content within the dload folder but keep the un-extracted zip also as it is.

4) Apart from 'update_sd.zip' you will also find two subfolders inside 'dload'.
In my case the two subfolders were '... 'update_sd_CLT-L29_hw_eu' & ''update_sd_CLT-L09_hw_eu'

5) Since my model was CLT-L29 therefore I deleted the subfolder named 'update_sd_CLT-L09_hw_eu'

6) Now rename the subfolder "update_sd_CLT-L29_hw_eu" to "CLT-L29_hw_eu" and on opening it you will find a same named zip inside. Like before extract its content within the subfolder and also keep the zip file intact'

7) That's it. Your 'dload' folder is now ready to be transferred to the USB drive for flashing.

8) Attach your OTG-USB to your device and restart your device. While restarting keep pressing Volume UP & DOWN key simultaneously. Your phone will now enter into dload mode and will start flashing after verifying firmware.

9) Bingo! you have now fully working stock rom. (Bootloader locked, FRP Unlocked, E-recovery functional again)

Note: Before doing this operation make sure your USB drive is perfectly working and exFAT formatted. You can check your drive by H2testW on windows. In my case my first USB drive was faulty and that's why dload was giving me errors.

4) Apart from 'update_sd.zip' you will also find two subfolders inside 'dload'.
In my case the two subfolders were '... 'update_sd_CLT-L29_hw_eu' & ''update_sd_CLT-L09_hw_eu'


Hi I've just made my own attempt and it eventually worked like a charm. only one thing: In my case those subfolders name were CLT-L29_hw_eu and CLT-L09_hw_eu. It's important not to rename them. (I removed L09 as my model is L29) Firstly I renamed it to update_sd_CLT-L29_hw_eu and software update failed. I restored then the original name (and also deleted meta-inf folders) and volia worked like a charm :)!

*Once again thank You very much for Your help. It can be life saver in future :)

I'm glad it worked. Yes... Yes.... I had also renamed it but forgot to mention it. I have updated the info. Thanks for pointing it out. In my case I didn't removed meta-inf folders and luckily it didn't pose as problem.

I think your case is of Xloader downgrade brick, as per your vendor country info I think you can try to flash CLT-L29 C432 build by the process mention above.

I think OTG dload solution should work. Is your bootloader locked? What about FRP? What was the last firmware you flashed?

How l flash it with what tools?

No any tool is required. You just have to transfer the dload folder to your EX-FAT formatted USB drive and keep pressing the volume up & down during restart of your mobile. Your mobile will automatically detect the dload folder and start verifying and flashing the firmware.

The detailed steps is outlined in post no. #4 of this thread. Hope it well help you out.

Bootloader unlocked & FRP unlocked.

I flashed the phone with the 9.0 CTL29 with FunkyHuawei but fail.

I tried OTG flash, nothing... Only fastboot access. Always BlackScreen ! lol

Since your BL & FRP is unlocked you can try to flash system image of your original build CLT-AL01 (try the most recent) via fastboot.
There is a tool which will assist you doing that https://pro-teammt.ru/huawei-multi-tool/ though I haven't tried this but you can dig into it. It might prove beneficial to you. You may get more info from their telegram group. https://t.me/Multi_Tool_8_TeamMT
Good luck buddy
