P8 Lite B170

Hi there,
I bought P8 Lite from Greece as a Single Sim.
I manage thru internet to find some firmware updates and i end up updating my P8 Lite with B170 and I made it finally dual sim.
Now Wifi, bluetooth are not working at all...
The only way to make wifi to work is to put it on top of the router, and then find the connection and working.
I saw on various sites that many people having the same problem with B170.
I made a search for downgrade, but still i don't have understand how i can downgrade my phone to a working firmware.
(I have tried resets and etc but nothing happened).
There is any solution to this issue ?
Please i need help to this one is like not having a phone anymore.
Thank you in advance.

How I Install an older firmware after Rooting the phone.
In the end i managed finally to root my P8 Lite,
I have B170 on it...
But I don't understand how I can install / Downgrade B120 for example now that is rooted..
The only firmwares i have is .zip files, when you unzip they have only the Update.App file inside.
There is anyone that can help me out with this issue ??

you need to copy the dload folder to sd card or internal memory,open settings,emui updater,update from local,good luck

I did that already, you cannot downgrade the firmware... all the times i tried, i have update fail msgs...
you cannot go from B170 to B132 for example...
thats why i am trying another way to do it...but no luck unfortunately, not even with google (i have spend like a week searching),
not even here i guess ....
i have root access, I also put TWRP... (Flashify and all the rest family of apps of that style) but still i cannot do nothing ...
And everything starts because on B170, Wifi and Bluetooth are not working at all....
I check also for custom roms, but no chance at all ..... just i need a way to put B132 back to the phone....

you need to extract update.app using huawei update extractor,after you can flash using fastboot command(for example fastboot flash SYSTEM system.img) extract in the folder adb(you need to flash boot.img,recovery.img,system.img and userdata.img)

Oh ! Thank you for your answer! (Y)
I did everything, in the start i tried to put the B132 but no luck because was an error on system.img flash.
In the end i manage to update (downgrade) to ALE-L21C432B052 !!
But still WIFI is not working !! I still getting the access denied msg, and only when i put the phone on top of the router is working...
Anyone has a solution for this issue...??
I was thinking that was the B170 (because i found many complains on the web, but seems something else is the problem)

it might be a problem with your antena built in the phone,in that case I sugest you to take your phone to a service

did you type the command fastboot flash SYSTEM system.img or fastboot flash system.img???

cristi.blidariu said:

This is use for B132 :
adb reboot-bootloader
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
but when i was typing the system flash i had an error, (so i never did the fastboot reboot)
I found B052 that was ready for flash (i mean without the UPDATE.APP, was with the .img files and adb,mfastboot)
and direct from the previous mode of the update i re-type the following commands.
adb.exe reboot-bootloader
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash cust cust.img
mfastboot flash system system.img
fastboot reboot
The phone was working before without any problem with wifi and bluetooth, ( i have it 2 months already)
before i make the first update for the dual sim story, wifi already was acting strange a bit,
and because i am traveling, first time i saw that was on an airport, the wifi couldn't connect on there router.
but i was thinking that is the airport router wifi problem.
But after i realise that was the phone, and after i tried B132, B136a, B170 and now B052,
the only way to get connected is to place the phone on top of the router.
* I was thinking that is the updates because when i search on google for wifi problems,
i saw some other users facing wifi / bluetooth problems after updates,
and i never think of a device problem..
Also i didn't find any of them with a solution about it...
So you think is the device?
You have any suggestion to try before i send it for service ? Just to clarify that is device problem...

This is the method that i try on my phone,i have download firmware ale-l21 c432b132,extracted with huawei extractor in folder adb,i use the command:
fastboot flash BOOT boot.img
fastboot flash RECOVERY recovery.img
fastboot flash SYSTEM system.img

I don't know how but this just helped me UNBRICK my P8 Lite ALE-L21. Thank you. After many tries.
How I solved the problem;
Used the huawei update extractor to extract the above files i.e boot, recovery, system, cust from downloaded firmware.
Then booted to fastboot mode and flashed them 1 by 1.
And for the moment of truth - "fastboot reboot" ENTER and I got my P8 Lite back. With all my settings & data.
This guide helped me do most of the commands - http://forum.xda-developers.com/android/development/guide-how-to-unbrick-huawei-p8-failed-t3260704

Well done
Sent from my ALE-L21 using XDA-Developers mobile app

how to recover?

Since I lost everything from the boot to the recovery to the system part to anything, i haven't been able to boot the phone;
I can access erecovery but when I try to recover the phone it stops at downloading and then says couldn't connect to servers so that's dead;
I can access TWRP but when I try to flash MM, it returns errors saying that it couldn't mount partitions (Vendor, cust and other...)
I can access fastboot mode. Some people suggested that I should try recovering using dload but the transfert rate to the sd card is taking forever;
Now I extracted everything from update.app using huawei firmware extractor (see http://imgur.com/MWeCCXi ) what should I flash (via fastboot) and in what order?
I would really appreciate the help.

Flashing cust and system returned failes
For cust: (failed remote: partition error)
For syst: (failed remote: sparse flash write failure)

Since I was running nougat before messing up the phone, it had to be System and Boot extracted from the nougat update

By Nougat I assume you mean the file that has been digged out somewhere in the web and that is floating around here in the forums?
Well we all don't really know what this build exactly is, which makes it very hard to reconstruct your errors and give you advice... I would never flash that but okay, that's why we are here
Do you have a TWRP backup that you can restore (and if no, maybe somebody can upload you a clean TWRP restore file)?
Have you tried flashing CM / AICP?

Hi there. Earlier I spent a few painful hours in the same boat you were in. I've managed to get back to a fresh install of the Nougat build from this thread, but can't seem the downgrade to MM using the (translated from Spanish) instructions found here (linked from that first thread). How did you manage to get back to MM?
(I should add that I tried to flash boot, system and recovery via fastboot without any success).
Cheers

May god have mercy on your soul.
For the downgrade, I didn't use the b161 directly. I flashed some oeminfo provided in the same folder as the TWRP. Then used b150 ans the three boutons method. Worked like a charm.
Hope it will help you downgrade your phone.

I have the same problem, someone could explain it to me step by step, please

I got the same problem. Flash firmweare with fastboot, download ota with firmweare finder, copy update.app on your pc, extract with huawei extract tool boot.img, recovery.img and system.img(put the extracted images in the root of fastboot folder on your pc) and flash them with fastboot.
Open comand promt and write:
1.cd /adb (hit enter) between cd and /and hit space
2.fastboot flash boot boot.img
3.fastboot flash recovery recovery.img
4.fastboot flash system system.img
5.fastboot reboot
and then wait the phone to reboot.
You have installed android nougat and now you cannot go back to marsmallow cuz partition size is different.

Thanks m ArluS but it does not work, the flash way around the terminal but upon reboot goes into eRecovery screen and not in, looking obviously some package for download via wifi but hangs failed ... giving me ideas?

I will share a way I got erecovery to work. I was brave and do not recommend this. If bricked do not blame me. I formatted system. Once system was gone it worked.

Formatted in fastboot then went erecovery.

OREO EMUI image files BND-L21 UBL

Hi everyone,may some of you need to back to stock Emui here some simple method which working fine, and i've try myself.
Things needed:
-Download these 4 images files, you can get it here
https://mega.nz/#!0s9y0QJA!dqtNYSObqGXZvx-z4z6c4W6Az4_kRS7rnvzKzkgQpms
-Make sure you have adb&fastboot working, you guys really know what's this really well.
-Download and extract the files, make it easier folder/dir.
-Flash each files as its named
Fastboot flash recovery_ramdisk recovery_ramdisk.img
Fastboot flash ramdisk ramdisk.img
Fastboot flash cust cust.img
Fastboot erase system
Lets wait till process done
Fastboot Flash system system.img
When you need to re-lock bootloader use Huawei Multi-Tool
And all those files extracted using Huawei MT, based on latest Oreo HW_eu.
Don't try to use the files on other model, when you do..do it with your own risk.
I decided to type and flash it manualy after faced some error on system partition using Huawei MT.
