P20 Lite - ANE-LX3/ANE-L23 - downgrade

[Sh4d0wk1ng]

I've been trying to downgrade the firmware on ANE-LX3 -ANE-L23 with a locked bootloader. I've used the firmware C605 to successfully downgraded it to 8.0.0.148. Unfortunately, that is still to high for DC unlocker and HCU to read the bootloader code. There is a lower firmware available for this phone that I found in FF but I'm not able to downgrade it. I tried renaming files without success. I was wondering if anyone has this type of phone and if it is possible to downgrade it?

EDIT: 5/9/19 I noticed this thread has become a bit popular and thought I should updated it. Yes, It is possible to downgrade, and unlock the bootloader for ANE-LX3. Thanks to the help of Bryan stelios. I, however, only have the L23 (C605)variant and I'm not sure if it'll work on other variants. You have to pay 4 euros for DC Unlocker to the read bootloader

download the dload folder from the links above.
place it on the root of your sd card.
Press volume + and - and power button until starts installing firmware.
You might need to do a factory reset upon restart.
Go into settings and enable the following
USB debugging - activated
OEM unlock - I do not remember, search in Google if you have to deactivate it, or activate so that you do not bother the FRP

and that's it, that's how you downgrade to a low firmware that can be used with DC unlocker.
there are many guides to unlock the bootloader see here.

But basically this is what happens next
Use DC Unlocker to read the bootloader. (Save this number!!)
unlock the bootloader by going into fastboot and then using the code (see link above to do that)
Once the bootloader is unlock you can restore the firmware in many ways, the way i did it was restoring it with the firmware I downloaded for the C605 variant from androidhost.ru restored firmware - update to latest update via settings, installed twrp and magisk and boom you are done.

Normally, extracting the files in the dload folder works. or that's how it worked in a previous Honor 6x device I had. Unfortunately the Update.app file for this model is larger than the FAT32 4GB size limit. Dload does not work with Exfat. it fails at 5%. I only been able to used firmware for downgrade from Androidhost.ru but there is not firmware lowered than 148(C605) available. but the 131(C605) is available in Firmware finder. Does anyone know of a method of using the Firmware finder to downgrade for this model? If not, I might just returned this phone and look for an ANE-LX1.

I have made a guide with the right firmware etc.

 

[Sh4d0wk1ng]

Yes, but it only applies to the ANE-LX1. the firmware used for downgrade is the one available at the androidhost.ru. the lowest firmware version there is for the ANE-L23(C605) is 148. This is too high for HCU/Chimeratool to read the bootloader code. I'll be returning this phone to opt for a ANE-LX1. your guide looks great and well explained. Thanks.

you can by using the firmware files at androidhost.ru. they even have a readme file on how to used them. basically you just copy the dload folder on the sd card. I haven't figure out how downgrade using the Firmware finder files.

Did you read the updated post? I am the OP, I tried it on my ANE-LX3/ANE-L23 and it worked. Bryan Stelios also tried it and it worked for him. There's a Youtube video with the steps linked in the description. I can only confirmed it works on the (C605). This is to bring the phone to a low enough firmware that can be used with DC Unlocker to read the bootloader, that you can use to unlock the phone.

Can someone repost links? The google drive link is down and the file is too large for mega.

EDIT: LX3 here managed to download the mega link with assistance from a 3rd party program and with that got the bootloader code with dcunlocker

C:\Android\platform-tools>fastboot oem unlock mycodewashere
(bootloader) The device will reboot and do factory reset...
OKAY [ 35.873s]
Finished. Total time: 35.874s

However now after factory resetting I am stuck on build 8.0.0.046(092Y) and cannot receive OTA updates.. Any advice?

 

[emaf94]

[paulpr7]

Hi! Can anyone please confirm if this method still works?
