[HELP] Error with update to android 7 (error code 7) - X Play Q&A, Help & Troubleshooting

Hello everyone!
I have a problem with the firmware update
XT1563_LUX_RETAR-MOVLA_6.0.1_MPDS24.107-52-5_cid12_subsidy-MOVSTLA_CFC.xml.zip I flashed on my XT1563 and it does not accept the update. The update file, from what I could see, is called Blur_Version.24.201.5.lux_retar.retar.en.AR.zip
I flashed that firmware and the last TWRP (310) but the update does not come before or after the SuperSU. (Error code 7 .. ¿?)
I need to update before put the TWRP ??
Thanks!

Updating using the update file requires you to be completely stock and that means not having twrp installed or any other change in the stock rom however minor it maybe.
I don't know about whether an unlocked bootloader creates problem in that.

How to update from VNS-L21C900B170 to Nougat

Hi there!
I have the P9 Lite (VNS-L21, Single Sim)
Out of the box, it came with branded ROM Version VNS-L21C150B130
I've successfully updated to VNS-L21C432B170 (with dload method) but that changed the version to VNS-L21C900B170.
I don't have any problems with that, the phone runs flawlessly, but i can't update to Nougat.
How can i update to Nougat and what's the suitable version?
Any Help?
Meanwhile, i've unlocked bootloader, installed TWRP, i've flashed oeminfo's form C432, tried a few Nougat Roms but none successful.
(All fail while verification)
Finaly I've rolled back to C432B160 and then updated to C432B170.
From "Software Update" I got notification for updating to C432B370 (1,24GB) but the result is "ND90M Test-Keys".
What am i doing wrong?

So i have to re-unlock the bootloader and install twrp to flash Nougat from scratch.
The problem is that i'm on C432B170 and i get a notification for updating OTA to C432B370 which is 1,24GB and gave me test keys... How can i flash the "hw_data" after the OTA update?
Any answers?

Update WAS-LX1AC432B185 to WAS-LX1C432B197

Hello I have a WAS-LX1A with the B185 I can not find update, with "Huawei Firmware Finder" I found the firmware B197, I tried to flash (FullOTA) it but it gives me error. The phone is not branded, how can I install this firmware?
P.S. WAS-LX1C432B197 is WAS-LX1AC432B197 (typing error)
Curious about this myself.. Is it even possible to flash firmwares that hasn't been signed/approved by Huawei??

[Firmware] Which firmware should i use to update to emui 5.xx with VNS-L31 C432 B226?

My phone had to be repaired last week, and the Huawei repair service changed everything in the phone except for the backplate.
However, I am now stuck with emui 4.1.2 in firmware VNS-L31 C432 B226, and i can't find a replacement firmware for the system.
The phone shows no update available in stock.
I have TWRP and magisk installed atm, just so i could try and get a different firmware with emui 5.1 or 5.0 at least, which I did to no avail.
Is there any way to find the correct firmware compatible with this phone?
Googling this firmware gives me no clues as to the correct path to updating this phone.
Should i use an adb/fastboot command prompt to update it, or use the dload method, or even the extract the SYSTEM.img from UPDATE.app method?
I just don't want to revert to an "earlier" version of the firmware with the dload method just to have my phone bricked.
These are the firmware i tried already:
[TO BE UPDATED]
TL/DR:
I have a Huawei P9 Lite repaired to a stock:
Firmware: VNS-L31 C432 B226
EMUI: 4.1.2
in Portugal.
I want to know a compatible firmware or series of firmware patches so i can get
Firmware: VNS-L31 C432 Bxxx
EMUI: 5.xx
Thank you for your time.
Hello,
it's strange that with an unbranded european firmware your phone didn't upgraded to android 7....
Anyhow i never done a forced upgrade but if i were you i wil try with HWOTA update, like explained in this thread.
So first make all your necessary backups, then unroot and finally follow the guide to upgrade.
P.S.: If your phone is dual sim try install B370, if single sim try with B371.
All the best

I tried a bunch of firmwares for emui 5.1 that didn't work, or which had NFC and bluetooth not working. I ended up downgrading to B160, and am now reupgrading to B370 after checking that both of the previously mentioned are working properly. I will update on this issue asap.
Also, it seems like the firmware I originally had was updated in march 2018, so it was really an updated official firmware with emui 4.1. What a weird setup. Could it be to make sure the NFC and bluetooth would be working? I just don't know...

Yeah, downgrading to B160 should be a good choise..
Use then stock updater to look forward

I did it and it worked, however i flashed the recovery partition of version VNS-L31C432B380 with TWRP and now can't do a OTA update to B388.
Should I extract the recovery img from a b380 FULLOTA update and flash it to my recovery partition with fastboot?

Hey,
surely without stock recovery OTA updates won't work,
so yes try flash it with fastboot, then update to the latest/wanted firmware and finally unlock bootloader,
flash custom recovery and root (even if wanted).
Best regards
