Update to lollipop failed to install - Huawei Ascend G7 Questions & Answers

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!

Failed to re-lock P9lite VNS-L31

Hi!
Got a problem, need to send my p9 lite to service bc it fell with me into water. it still works, but I assume a chip is frozen because neither the wifi nor bluetooth can be turned on. I'm afraid theyre not fixing my problem because I unlocked it.
I flashed twrp recovery, rooted, but already flashed the stock rom and unroot again.
When I tried to relock with adb and bootloader code, I got the error code root risk is too high
Tried to install other stock roms again and a lot of stuff, but none of it worked. So I tried to relock via dc-unlocker. com but didnt work. But now it says when I restart "your device has failed verification and may not work properly." instead of "Your device has been unlocked and can't be trusted." and when I tried to use adb to relock with the bootloader code it says "remote: stat not match" ~ got a new bootloader code??
I'm desperate, can anyone help me?

ps i was on android nougat but i think there any os now because the phone dont boot sorry for my bad english hahah

Bricked Honor 8 Lite PRA-AL00X

Hey Guys,
My father bought his Honor 8 Lite in China and asked me to try and "westernize" the phone. I have some experience installing ROMs and rooting phones but I am a beginner in this. Anyway, I try following these instructions on how to rebrand the phone, and I ended bricking the phone.
After I installed the new oeminfo on the internal memory (because I didn't have an SD card handy), I couldn't access TWRP anymore. If I try booting the phone I get to the Huawei eRecovery, which only offers the option "Download latest version and recovery" and gives the message "Getting package info failed".
I can also access fastboot&rescue mode, but it now says: "PHONE Unlocked; FRP Lock", and when I try to flash TWRP again, I now get: "FAILED (remote: Command not allowed)".
I also tried booting the dload file from the russian firmware from the tutorial that I put on the internal memory, but after 5% I get the message "Software install failed!".
Do you guys know what did I do wrong or have any suggestions for what can be done to save the phone? I have run out of ideas and clearly don't know very well what I'm doing. Any help will be greatly appreciated.
