Issues with Huawei P20 Lite Bootloader code

[endrigo]

Hi, if I've understood correctly, have you downgrade your old firmware ANE-LX1 8.0.0.150 (C432) with ANE-L21 8.0.0.125 (C432) new one without any kind of problems with this metod?
And obviously before unlocking your bootloader?
Thank you for your respose

Great ! I've downgraded mine from 168 to 126, then DC-unlocker-client with 4 credits gave me bootloader code and all works fine ! Now I have unlock bootloader.
DC-Unlocker great service !
Thank you Brenza , thank you to all.

Update sussecfull. Phone restart and after patch i get factory reset too.

So i dont know its new or old version still?

After i click in DC Tool = unlock and then network unlock and phone reboot after this but i cant read, see my unlock code!

So i want my unlock code and press read my unlock code but Insufficient credits !

So my question is, how much credits more to get my unlock code?

In the price list cant read any exactly price

So can you tell me whats wrong?

Better i have click read my unlock code before?

Is click = Network Unlock wrong Option?

You should have pressed on the "Read bootloader code" button.
I don't really know what "Network unlock" does, sorry.

If you need bootloader unlock code then press "read bootloader code" not "read unloc codes". Network unlock has nothing to do with bootloader, it's work network/operator unlock clearly.

Sure, here it is! It works for both ANE-L01 and ANE-L21
This firmware is the official one from Huawei P20 Lite for the european market (code C432), you can also download the firmware for other regions by looking at the archive's name and getting those from the original source.

You have to extract the zip file and copy the Software\dload folder at the root of your the sd card, do NOT touch the files inside that dir. SD must be formatted in FAT32
Once the sd card is ready you can downgrade by dialing *#*#2846579#*#* - select Software Upgrade and then SDCard Upgrade
If you cannot boot the phone or the above trick does not work you can also power it on and keep pressed both volume+ and volume- keys until the "updating" screen appears.

By installing this firmware you will erase all data on the phone internal storage, make a backup with HiSuite or another software before doing that.

You're the hero we don't deserve.
Thank you!
Just updated to Pie (android 9) and the bootloader was blocked again, with your help, I was able to unlock the bootloader and update properly with bootloader unlocked.
