How to reanimater your mate after bootloap???
We have 2 methode for now.
Firts it's restore twrp backup and secend its fastboot and downgrade pack
If you use twrp backup and its work very good for you but if dont work you must use fastboot method
1. Power off device and go to fastboot
2. Extract file from update.app for lollipop :
- system
- cust
- boot
- recovery
- userdata
for Marshmallow extract :
- system
- cust
- boot
- recovery
3. Install adb drive from this topic
http://forum.xda-developers.com/showthread.php?p=48915118
and copy all file to C:/adb on your windows
4. Open CMD as administator and write this commads
cd C:/adb
adb fastboot
Now you on fastboot mode
When you extract file frome update.app you must rename file :
10.boot.img to boot.img
11.recovery.img to recovery.img
13.cust.img to cust.img
14.system.img to system.img
If you remane you can flash img file using fastboot methode using cmd
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
It's take very long but wait. When its finish take micro sd adapter and put you micro sdcard and connect to pc and copy full rom :
If you use lp file because you have bootloop on lp you must flash that same rom what you flash file using fastboot
and do it that same for marshmallow
when you copy put your adapter to slot of microsdcard in your mate7
Now power of your phone and try go to flash method using 3 bottom on you mate7
VOL+ POWER + VOL- when you seescreen on realese power and wait. Now you see how rom its flash.
If you have error you must use downgrade pack from mm to lp and flash.
When its flash you must flash lp.
If you have error you must use downgrde pack from lp to kk and flash.
When its finish you must flash kk rom.
Now you back to rom after bootloop and you can try again flash rom what you want.
Finish guide for noob
Cheers :highfive:

Thanks for the guide. I want to restore to MM from kk using twrp? Is it possible? I only wait 5 minutes after restore reboot then I think something must be wrong so I restore my own backup. I will give a try again.
Sent from my HUAWEI MT7-L09 using XDA-Developers mobile app

No you can't do it you must first flash kk second lp and then you flash mm

Hi buddy, your guide is gold. I explain what i did up to now. I wanna know how to proceed safely.
1) 2 year old MT7-L09 Mate 7. Long time ago i go bootloader unlocked, rooted and updated to lollipop stock. dont know which firmware version.
2) TWRP 2.8.7.0. Wanted to factory reset after long time no using the phone, ended up wiping OS and god knows what else.
3) Can access fastboot and TWRP.
4) Tried stock recovery and 3 button method to downgrade or install stock update.app. Nothing worked it always got stuck at 90%.
Up to there nothing worked. I guess i must have damaged some critical files.
Then i found your guide and wanted to try making a lollipop restore from TWRP. Found a file.
Now, if i understood what you have written in red, i may have wiped oem information like country and vendor. Maybe thats because i cant install stock from huawei.
How can i restore that info? is there any way i can backup my bootloader info, or retrive my country and vendor info?
How do you suggest me to proceed safely.
Thanks
Sebastian

You can manual push oem info to correct partition. What country you from

Im form Argentina. Phone was bought in US. I dont mind putting any country version as long as i can bring it back alive.
Luckily i have saved phone imei, serial number and id in evernote. Maybe that can help to figure it out.
Do you have a procedure or guide to do that you are suggesting?

if you have unlocked bootloader you can try use SRKToolHuawei-Lod-Chong-V2.0-20161002 to change oem info and then try flash correct your rom using dload method. But if you change region you must unlock again bootloader but when you go to fastboot you have unlocked. Unlock again because its locked

Im on C66 how to update on newer firmware version?

So,
My phone is vns-l21c66b131 and is there any way to update to newer versions without rooting and if possible can someone write steps on how to do it?

If you use <SEARCH> you find followings:
<After a few day of reading users personal experiences regarding upgrade to Android 7 Nougat i make the big step myself...
My device is VNS-L21 model and entire process goes flawless...
Device state was stock MM VNS-L21C432B150, bootloader lock, dualsim enabled.
1. Unlock bootloader folowing by Automatic Factory Reset.
2. Flash TWRP
3. From TWRP i flash Meticulus TWRP
4. Reboot to TWRP and flash update.zip and update_data_full_VNS-L31_hw_eu.zip, both flash ends with errors, without reboot between flashes.
5. After that, i reboot device and boot in system ok, start configuration, etc.
6. I reboot to fastboot and flash Nougat Recovery reworked by @BadWolfYe
I am not experienced camera bug, all works fine and i have now a fully functional phone.
BTW, dualsim remain enabled and works both sims.
Thanks to all contributors for these pieces of firmware, first of all to @BadWolfYe!>
For that's is <SEARCH>, not to open another topic for same problem...

Thanks for the reply, but I'm not talking about Nougat, I talk about MM b161 update. How to do it if my carrier is c66 and the newest update there is b131

If you want to stay on C66 you have to wait to OTA updates...
If you make any upgrade via dload folder on sdcard your phone will go from C66 to C900 (global)
Another alternative is to debrand your phone to C432 (hw eu)
For any of this is treated here in some topics...

So I just need to create dload folder and put the zip there?

The zip is ok for update from TWRP.

Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help

Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:

Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤

this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.

Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.

hello guys! im currently on lineage os 14.1 by meticulus, i wanna revert back to stock mm but i cant. i flashed the custom rom from mm using twrp recovery by meticulus, but now i cant even boot into erecovery! can you pls help me!:crying: DLOAD method doesnt work!

[Q] Stuck on custom rom, sim not working, want to go to stock

Hi, I have tried all night to install a custom rom and recovery for my huawei p9 lite (VNS-L21).
I've managed to flash Ressurection Remix with Meticulus' TWRP but now my sim card doesn't work.
It's detected but i can't make calls, send messages or use data.
I want to go back to stock EMUI but i don't know how exactly. I've found an update.app for my model but it won't install. I've lost my recovery and i can't flash a new one despite the bootloader being unlocked. Can anyone help me please or guide me how to restore it back to it's original state?
If it helps it was the VIP mobile Serbia model, CM-hi6250.
Thanks in advance, I really want to just have a working phone

If you lost Twrp you must flash it via fastboot command. After that it is neccesary to flash Oem C432 zip. In that step you can chose if you want oem for single or dual sim. I suggest to flash Oem C432 dual sim using TWRP.. On SD card you need to place in dload folder firmware full b160 in format update.app. When the Oem is flashed turn off phone (please dont let to reboot phone after flashing of oem ) , press power+volume up+ volume down, hold them a few seconds after you see logo screen, release buttons and full revovery will start. Oem L21C432 dual sim flashable zip file you can find here or in our local forum on benchmark.
All the best.

i had this problem too cause i was not attentive...
Create a dload folder in your sd card and search for an "update.app" file that is right for your device. Place it in the dload folder then press power button+ volume up+volume down to do a force stock ROM installment after install remove sdcard enter stock recovery make a wipe...restart done
Tell me if it works<3

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
Cheers

Hello,
I reinstalled the custom rom that I found on the net: C432B414 with Hurupdater.
It works.
However, the bootloader is still unlocked ... however, I would like to return to the factory configuration with the bootloader locked.
