Issues with Huawei P20 Lite Bootloader code

[fluoro]

Thank you so much Brenza for your link, you solved all of my issues!

[Undi95]

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.

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?

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.

[Brenza]

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

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.

The downgrade part uses an original Huawei firmware and no exploit at all, I'd say it's quite safe.
I cannot speak for the code-retrieval part as I do't really understand how they managed to obtain it but I think it's not dangerous.
After the unlock what you do is entirely up to you, if you touch the wrong partitions you could definitely break the phone but it's not related to this procedure itself.

European region is exactly what I need! Thanks for the instruction.

I asked for a refund from DC-unlocker last week, guess I will purchase again, lol.

No problem at all, if you like I can upload the firmware on google drive or something else and put the link here. I've had quite the hard time to find it.

This is great finding. Would you mind sharing the link? I have a dual-sim ANE-LX1 as well.
Thanks!

[Valdemaras]

You sure can.

Got it, it's not only possible but also safe and very easy!
I don't know if disclosing any "how to" info here goes against the forum's rules but flasing back the ANE-L21 8.0.0.125 firmware did the trick!
If you have the single sim model you have to flash the ANE-L01 firmware

I got the code and permormed the unlock successfully

Great news, thank you for the feedback.
