Hi folks,

I got this CLT-AL00 (CN) and the phone is amazing, though is running the Chinese firmware and it has some restrictions in Europe. I did some research today about changing the firmware to CLT-L29 and it confirmed what I feared.
But still I will ask anyway because long time since my last Android, can I install the Stock version of CLT-L29 and success? or it will brick/fail because its a firmware for another country?

Right now the phone is not rooted and it runs:
- Build number: 9.0.0.187 (C00E57R1P15) GPU Turbo
- EMUI version: 9.0.0
- Bootloader Version: Chipset-boston9.0.0.001(0416)_FASTBOOT
- Vendor Component Version: Chipset-boston 9.0.0.001(P.19042504.china)
- Cust-CHN 9.0.0.1(P.EXT4)
- Product Component Version: Product-CLT-LGRP1-CHN 9.0.0(P.19010502)
- Base Software Version: CLT-LGRP1-CHN 9.0.0.187
- Cust Software Version: CLT-AL00-CUST 9.0.0.57(00)
- Preload Software Version: CLT-AL00-PRELOAD 9.0.0.15(c00R1)
- Vendor Country Info: Vendor - all, Country - cn

Another extra questions, do people pay for getting the bootloader code or Huawei still provide it? Or perhaps there are other ways...

You cannot get the code, and without it you cannot do anything. Use the phone as is.
Thanks!

But what about this method? I found it in multiples sites and it's not mentioned the need of having the boatloader unlocked.

Flash Huawei stock Firmware Via Normal Update
1- Create a new folder on your phone storage or in your SD card, and rename it to dload.
2- Download & extract Huawei Mobile Stock firmware & copy the UPDATE.APP file on dload folder
3- In your Huawei Mobile, Open the dialer and enter:
*#*#2846579#*#*
ProjectMenu => Software Upgrade => SDCard Upgrade => OK
4- Select the Update.app that you copy on your phone storage or in your SD card.
5- Now Wait until the installation process completes.
6- When the installation completes, the phone will restart automatically
7- If you have the Data File and you want to flash it to,
8- Create a new folder on your phone storage or in your SD card, and rename it to dload.
9- Download & extract the update_data_Xxxxx & move the new update.app to the dload folder
10- In your Huawei Mobile, Open the dialer and enter:
*#*#2846579#*#*
ProjectMenu => Software Upgrade => SDCard Upgrade => OK
11- Select the Update.app that you copy on your phone storage or in your SD card.
12- Now Wait until the installation process completes.
13- That's it! the phone will restart automatically
