How to downgrade from USA b190 to b183 or b167 (stock) - Huawei Mate 9 Questions & Answers

Is it possible to downgrade to older firmware on the Mate 9 from b190 to the prior ones? I want to see if battery life is better on the older stock rom. Do I have to root to be able to do this?

You can flash HWOTA method for downgrade firmware.

Little Help - Update ROOT Honor 8 from FRD-L09C432B131 to B360 (Nougat 7.0)

Hi All,
I would like just a little help on how to update correctly a rooted Honor 8 on MM 6.0 to Nougat 7.0 ?
Meaning from firmware B131 to B360 ?
OTA doesn't work, even when i disabled ROOT. I also tried bootloader to force update but it fails during the process.
Any idea what to do next? Do I need to relock the bootloader and remove TWRP before proceeding?
Thanks very much!
Unroot, flash stock recovery for the emui version you have
I guess this would also include a full wipe? Or is it possible to just update without wipe and still get a good result?

Which version of nougat should I flash on my FRD-L14 device with L04's firmware?

I just did the rollback package on my FRD-L14 device. The only rollback package available is the FRD-L04 version. Now after successfully flashing my phone says its model number is now FRD-L04. Is there a way to get it back to FRD-L14? Does it even matter? Also, can I get the nougat update for L14 or just the L04 one?
Check out my post on https://forum.xda-developers.com/showpost.php?p=71825814&postcount=17
The process should be the same. Running L04 on L14 will cause Android to believe it's tampered and won't enable things like Android Pay.

Do you have the specific dload file for your country? if u dont then downliad it from your countrie's huawei/honor website.(idk if its still there)

Don't u get OTA updates?
Sent from my Honor 8 using XDA Labs
He can't get OTA update, since he is running on rollback package OS, you have to flash rollback package and firmware package (Marshmallow). After doing this, you can easily search for updates via Update in Settings.
That means you're stucked on FW C900 which is just for rollback to EMUI 4.1. Download full package from Huawei website and do the dload method to flash the correct FW.

Last official firmware ????

Hey guys
Iam get my new phone rebranding from AL-00 to Frd-l19 At MM 6.0 Emui 4.1 and get update nougat give me that firmware Frd-l19c432b360 and nothing update again ?!
Is that right guys or i have a problem ?!
My phone 4/32GB
Hello radhaddiab
I advise you to rebrand your FRD-AL00 phone to FRD-L09 (C432B131) and maybe you will have a more recent OTA update.
And IMHO, you should try to update to B380 (Above this version, it can sadly bootloop with rebranded China models - AL00 and AL10 - of Honor 8).
I have one AL00 phone too, rebranded to L09 (C432B131), and OTA update find B390+ firmware to install. (if installed, phone bootloop for me...)
But if I go to "Menu" (of Updater App) and click on "Donwload the full update package", I get the B380 firmware to download. After update, do a "Factory reset" (recommended).
If no luck with OTA updates, try the "RedLotus" method (requires a computer): https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306
You must dowload and install HiSuite v5.0.1.300, not the latest one: https://www.filehorse.com/download-hisuite/28890/

For L19 > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v77475/f2/full/filelist.xml
For L09 > http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v77476/f1/full/filelist.xml
Good luck! =)

I only advise you L09, because you have AL00 model (32 GB internal memory). If it was AL10 model, I would advise L19. (64 GB)
But... that's not really important. ^^
And trying L09 can give you a different OTA firmware update than L19. But it's safe to update up to B380 (not more), that's all.
If you bootloop because you tried to install a more recent firmware, you can always "rollback" to B131.

With a rebranded china model to any Lxx model : B380 is the last safe update I know working, actually.
I think it's possible to have a more recent update if you revert your rebrand (to original AL00 model); Last AL00 stock firmware is B396.
Yeah it's sad... :crying:
