How I Install an older firmware after Rooting the P8 Lite.

In the end i managed finally to root my P8 Lite,
I have B170 on it...
But I don't understand how I can install / Downgrade B120 for example now that is rooted..
The only firmwares i have is .zip files, when you unzip they have only the Update.App file inside.
There is anyone that can help me out with this issue ??

You need the Huawei Update Extractor Tool (HUET) to get the flashable imgs from the UPDATE.APP.
Note that you'll NEED to flash B052 FIRST otherwise you'll ruin your baseband until you do so (no baseband means no IMEI, and that means no cellular) .

[HELP]System update failed [ANY FIRMWARE]

Hello, im here again with another "brick" which i cant fix by myself for one day. I was on beta firmware B313, but i decided to downgrade to B200, now, im bricked, i cant flash any firmware, everthing ends with error at 5 percents, recently i have B313 files (boot.img, recovery.img) because thats the only version i can boot into recovery from and its at least trying to boot into system, but after logo it restart. When i flash files from B170 or B200, it cant even boot into recovery, can anyone help?

you had to first install the b300 downgrade file and then the B170 firmware. You can try to install it, it takes you to the version b300

Thank you very much, it helped. Every tutorial to unbrick the phone mention only B200, not B300 first so i didnt know. Have a nice day.

P9 lite vns l31 soft bricked.

Hi there,
So i upgraded to emui 5(c432 version) europe version manually using twrp for emui 4.1 ( C432 because there was no c185 version which i needed because the c185 is the carrier unlocked version for Africa and i had Vodafone carrier locked (c02) software before and i wanted an unlocked version. this was before the ota came out for vns l31) but it wouldnt flash the data file, so i installed revolution recovery and flashed the data file. I experienced a bug where the phone wouldn't connect to my pc, it just charged. So i tried to flash different software (c185 had been released officially) but revolution recovery couldn't flash the update.app file and i accidentally flashed the emui 4.1 twrp and now my phone is soft bricked, please could i get some help as to which software to flash using dload that wont give error at 5%

modelnimber HI6250 and VNS-C432B130

Good day,
After installing b130 firmware this is now what my screeninfo says.
It has HI6250 as modelnumber and
VNS-C432B130 as buildnumber.
Notice it doesn't say L31 anywhere.
Is this still oke and will I receive updates or do I have a problem to fix?

You should try to restore the phone. Do this:
Save the code to unlock the bootloader somewhere safe
Flash c432 oeminfo
Dload b160 firmware

how to come back to stock rom?

Hi, i've a p smart Fig-Lx1 with rescue rom installed (after brick) from figo folder , FRP and Bootloader unlocked, no root. When i try to install an update via ota, an error occurs. When i try to factory reset smartphone goes into erecovery and can't download any firmware. The only firmware that i can install is rescue firmware via command prompt. I want to install last firmware but i can't. can you help me?tnx. P.s. After installation of rescue rom , if i try to relock bootloader , i've a bootloop into erecovery and Twrp recovery.

Is bluetooth and everything working OK? Try upgrading through Huawei Firmware Downloader app.

i'll try to use this app... thank you for now

nothing...

The firmware finder for Huawei is the way to go, that's how I reverted back to the stock rom after I bootlooped

Problem solved with firmware finder, thank you

I also wanted to go back to the stock rom so I flashed the stock recovery and downloaded a stock ROM image (mega.nz/#!qbRyCYiI!G-1ctQEUKj_2ksHS-rU-yWiF8YZyiYSllQBSBbHoC78).
I thought it's signed but when I relocked the bootloader it only showed the eRecovery so I had to unlock the bootloader again and now I can use the ROM and it receives the latest updates.
I want to lock the bootloader because the message before the booting is pretty annoying but I don't know if my ROM is signed or not. Is there a way to check it before relocking the bootloader? Can it be in signed state due to the official updates? Are the firmware finder updates signed?
