HwOTA8 for Huawei P20 Lite​

1. On the phone, make a backup of all data (since during the upgrade all data will be erased). This is an obligatory condition.
2. Unlock your bootloader: (There´s no way around it (unfortnuately), but after the procedure your device will be locked again, so don´t worry!). The device will make a factory reset, so once again, BACKUP your files!!!!!!!!!!
3. Enable ‘USB debugging’ and ‘OEM Unlock’ option from setting>developer option>. To enable Developer Options, go to About phone and tap the Build Number 7 times.
4. You must download three zip-archives with a full "Full OTA" firmware on which you want to flash (If you look through in the FF (FirmwareFinder), you see there are 4 archives for China and 3 for other locations. You must to download for the version what model and location you will have after the firmware);
5. Add the downloaded files to the folder "HWOTA\Update" and run the .cmd file, it will rename them automatically according to the template:
- update_data_full_public.zip to update_data_public.zip
- update_full_....zip to update_all_hw.zip
- update.zip don't rename
and will be repack firmware automatically!
6. After run the universal batch file update.bat in the "HWOTA" folder, which will provide an opportunity to choose the required work option (change firmware/rebranding (change location)). FOLLOWING INSTRUCTIONS ON THE SCREEN OF THE MONITOR - the entire process is accompanied by prompts.
At the end of the process, everything should work fine... Be prepared, the bootloader will be locked after changing the location or firmware as a FullOTA.
7. If suddenly it turned out "bootloop" - go into the stock Recovery and make wipe.

PS: To change the firmware using the SD card, you need to create a folder "HWOTA" on the SD card and copy three firmware archives with the changed names (see above). In the batch file select item 1 "SDCard HWOTA directory"

HI,
I tried this but the bat file has only two options..
1. lock boot loader again
2. Not to lock the bootloader

if I choose 1, it just locks bootloader rebooting to fastboot etc..etc..
If I choose 2, the app closes..

How to make the rebrand or change firmware using this tool ??

Thanks in advance.

Confirm it working! Dead ANE-LX1 from C10 (RU) to C432 (EU) and update to 8.0.0.126

First flash oeminfo, then stock rom (All this by HwOTA8). Then use Firmware Finder with DNS changer included in to Multi-Tool 8 to install last update applied to your country-code in oeminfo.

 

[shecky]

Can you detailed more? After changing oeminfo from C55 to the C432 the phone make a full erase and the script stop because is asking for twrp in order to continue. I made this and very hard I make it to work again with a problem at the firmware version.
Now mine is 8.0.0.0. 46 (0ASV) wtf??

Just flash it again. If error at 60-70 % try flash without main zip, just with lx1/l21 zip and third , forge how it must be named, typing from phone. Of And this doors not work, then check country code. If changed (if u change it ofc) try firm finder + hisuite with DNS patch applied (can find in multi tool 8)

Ive just tried to use the HWOTA8 to update my P20 lite from C782 to C432.
Whilst it was a complete ball ache, Ive now ended up with a P20 lite C432 dual sim and everything working which is great
The HWOTA8 doesn't fully work, you can get the files to repack, change the names, but it falls down once it flashes the temporary TWRP, it wont reboot into TWRP. you need to open a second cmd prompt and reboot the phone whilst unplugging the usb lead and pressing volume up to enter TWRP.
Once there i was able to flash the new OEMINFO which went okay, but again it wouldn't reboot out of TWRP so it couldn't carry on with the firmware update.
I rebooted the phone and got similar software versions to above ending 46
In developer options OEM unlock disappeared and wasn't showing in bootloader, only phone unlocked.
I then restarted HWOTA8 and tried to bypass the install part and try and install the firmware update but that also went through okay but failed about 75%
Restarted the phone back into the normal system
I downloaded the firmware finder app and manually added the the correct customer version i tried to install, as the app recognised this 46 number
The firmware was downloaded via proxy and passed all the checks and installed correctly this time. went through okay and now the phone recognises it a c432 as i wanted and no longer c782 or 46.
The only strange bit was that after the firmware was updated, frp lock in the bootloader disappeared, for this to re appear again i had to relock the bootloader to get it to show back up again. i then proceed to unlock again and it still stayed this time.
Ive checked everything and everything is working okay now, Dual sim shows but even with second sim is inserted it shows all 00000000000. but the sim works fine and makes and receives calls as well as first sim
hope this helps anyone else before using this method you can make it work but it aint as easy as following the prompts.

Hi Daniel.
I downloaded via proxy with app finder (directly in the phone) firmware ANE-LX1 C432B126 but how to install it? Isn't showing nothing to update.

Hello
If you download with firmware finder via in app proxy,
once youve modified your wifi settings to localhost port 8080
go into your system update and check for an update, once its downloaded it will reboot automatically into recovery and update for you.
you dont install anything your self. the system does it all for you.

Has worked with methode of fabio87.
Thanks man. Now i want to have original recovery image instead of twrp.
which image should i write from update.app?
