Update to lollipop failed to install

Hi all, my gf have an Huawei Ascend G7 with EMIUI 3.
The phone is branded unfortunately, and I want to install EMIUI 3.1. I've downloaded the zip from the official site, put the dload folder in sd and start updater but I the phone reboots to recovery and I have an error (simply failed to install). Have I'm doing something wrong?
Thank you in advance

Same here. I have tried this build C469B340. I've unlocked my bootloader. I'm guessing the code in custom.bin needs to be changed. Anyone knows the operator this has been released for?

Btw, this is the error message I'm getting.
oemsbl version list check error
check_write_data_to_partition, write data error
Software install failed!

[Q] Question about fastboot

Okay I have ALE-L02C190B120 with unlocked bootloader and root in South Africa .
I tried doing huawei local update with C432B560 and it failed.
I tried this using stock recovery but rooted , which i know someone says wont work.
The thing is that I don't have data to download the C432B170.
So now to my Question:
Can i extract the B560 Update.app using Huawei Update Extractor and flash the system,cust,boot and recovery images safely without hardbricking my device which is currently on C190B120? and might the update work via emui updater if i just Unroot?

Did you tried put update.app in folder "dload", switch off the phone and press all 3 buttons together?

You have tried with update from sdcard.download lastest versione of firmware and rename .zip in update.zip and put the firmware in sdcard,go in recovery and select zip from sdcard and select update.zip.sorry for my bad english

Okay.. Bro.. I'll try..

Couldn't update ASUS ZenFone 2 laser 550kL
Facing the same problem
Baseband version - 202c10_10.0.0_160602
Build no. - WW_21.40.1220.1708.20160621
First I tried to update automatically through OTA update but failed.
Downloaded file from ASUS website (build no. 1877 ) and tried to do it manually by placing it in the root folder but still that failed.
ERROR - E: failed to mount / asdf ( invalid argument )
Please help with updation using simple method

flash stock recovery first if you want to do Gabbro16Hz method.

3gb ram varient of ze550kl has this kind of problem.
You need to download latest firmware from the asus' site. Place it in the sd card.
Enable usb debugging in developers' setting. Then boot your phone into fastboot mode. Connect phone to pc via cable.
Then put the tools.zip file in the pc and unzip it. Open that folder. Run 'flash all.bat' file. This will flash stock recivery to your phone.
Now boot phone into recovery mode. Select 'apply update from sd card. Select the firmware and flash. Then reboot. Work done. Your phone will have latest update.

Typically means that this version of firmware is not signed, or registered to work with your phone.

hello!
i have a p9 lite vns-l21c432b380 dual sim
some days ago i contacted huawei to get the bootloader unlock code. after that i unlocked it via fastboot, flashed elite twrp recovery 3.2.1.0. everything working fine til now. i then tried to flash from twrp latest lineageOS release but it doesn't seem to be working as on reboot i get stuck on "you're device is unlocked and it can't be trusted" screen with the options to boot system and erecovery. it just stays there, no sign of lineage os.
i tried to restore at least the stock rom via dload and 3 button method and to flash extracted bits frome the update.app file via fastboot with no success: i always get a "update installation failed" error, with the only option to reboot the phone to nothing
what am i doing wrong?

update: i tried to flash oem info for l21c432 dual sim from twrp, then retried to install via dload and 3 button method. no luck, still "software install failed" and nothing else

OEMINFO: ftp://XDA-Dev:[email protected]/Oeminfo/L21/L21_DS_C432_by_EasySR.zip
FIRMWARE: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66034/f1/full/update.zip

i'll try to flash both via fastboot, since the recovery won't now mount data
thank you

fastboot gives me "command not allowed", flashing via elite twrp 3.1.1 "invalid zip format". what am i missing?

You need to flash oeminfo with TWRP. (Unpack the arhive then copy the oeminfo.img on your phone)
And also , unpack update.zip .
Then make a new folder on sdcard called dload and put update.app there.
Then boot into dload mode and it should work.

i'm not sure of how it worked. now i have TWRP 3.0.2 installed and stock ROM VNS-L31C432B150. some how it changed from l21 to l31.
do you think there's a way i can flash latest lineage os or should i stick to b150? in case how can i do it?
thank you for patience and time
