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...

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
Hello! I have an P8Lite ALE-L21 unlocked and by mistake I delete the system.. Now I don't have OS to boot
What can I do now to have back?
Download the rom for your phone then install the rom using the recovery system op the phone.
If that doesn't work try flashing the rom through fastboot.

I tried both but it dosen't work
I don't find source with system.img
Use this http://forum.xda-developers.com/showthread.php?t=2433454&page=31 to extract the system.img
- Fastboot flash boot boot.img
- Fastboot flash recovery recovery.img
- Fastboot flash cust cust.img
- Fastboot flash system system.img
- Fastboot reboot
Use those commands and I hope it will be fixed.
Hi, my problem is with the L31,
I've trying to downgrade from Nougat to MM. I saw on the thread this steps and i followed:
"Fastboot flash boot boot.img
Fastboot flash system system.img
Fastboot flash cust cust.img (This one is in the second zip from badwolf nougat download)
Then I flashed badwolfs recovery b2 as that one lets me transfer files from pc to phone and followed instructions from htcmania from here".
The problem is that i didn't reach to downgrade and when i try to reinstall Nougat by TWRP i get this error messages:
" E: Unknow comand (errno) update_huawei-pkg_from_ota_zip: update package from zip failed"
"Updater process ended with error: 7
Error installing zip file '/external_sd/DLoad/Update.zip'
Updating partition details...
...done"
Now my phone stays freeze on the huawei logo and the flashtool doesn't even recognize my device.
Can someone help me with this matter, please?

Good luck
so now i restored twrp , i put the update app in sd card and it doesn't want to flash , i'm still trapped in bootloop but i have access to twrp now what to do now ?
I found the old twrp is okey for downgrade,
Just put b161 update.app into sdcard/dload and press volume down + power key.
but flash badwolf's twrp will get stuck in fastboot, though It's not really bricked.
hi, maybe you also have a solution for my problem.
i installed a wrong update via sd card (dload etc.), now my phone is just black no signal nothing. and it seems like a fastboot loop always when i plug into the pc im in fastboot without doing anything
when i try to unlock the bootloader i get "failed command not allowed")
and also when i try to flash the extracted files from update.zip i get the same error ("failed command not allowed")
by the way i didnt active usb debuggin or oem unlocking
please help thank you
I flashed 3.3.1-2 twrp and then installed a couple different roms to compare. Then I'm not quite sure what happened, I know I formatted and tried to install another, then I lost access to twrp. Even though it says I'm successful at flashing it, it won't boot into twrp or any recovery for that matter. What should I do? I've tried two different twrp's and neither will boot up. I've tried the .bat and volume+ and power, and I even tried with the fastboot boot twrp.img command.

So I tried to go back to MIUI and it did it again, I did the default wipe and tried to install it. It got stuck in a bootloop and wouldn't go into TWRP again. Tried what you prescribed again, but that didn't work. I tried using the command (fastboot boot recovery.img) and it just shut off. It's clearly not flashing TWRP, but I have no idea why. I tried both 3.3.1-2 and 3.3.1-3, neither worked. I tried flashing more of the fastboot ROM images, but that did nothing either. Any suggestions? I'm having to use my old moto g5 until I get this fixed, so help ASAP would be amazing. Thanks in advance!

Hello, good day. I just wanted to ask, (Im using custom rom now and my old backup is nowhere to be found) If I am going to flash my device to official stock rom, like if I flashed the older version (lets say the MM) can I still update my device today (up to nougat) through OTA update?
i think huawei cloud is the site where we download OTA updates from but I think is already dead.
(sorry if my poiint is confusing, I just really don't know how to explain it clearly)

So if I not mistaken, your build number is VNS-L31C185 EMUI 5 (correct me if I'm wrong).
Firmware finder and Huawei old server are down, so download service ROM.
IMO now you have two possibilities:
A) flash Service ROM using dload method, guide can be found in ReleaseDoc folder. The process will erase all your data and lock the BL again!
B)
- from downloaded ROM extract BOOT.img
RECOVERY.img
SYSTEM.img
CUST.img via 'Huawei update extractor' , follow Guide
(Note: CUST.img on Nougat can be found in the second archive)
- In fastboot mode flash extracted partitions using commands
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
- fastboot reboot
- Factory reset in stock recovery

Bro try this way out...
Download and install TWRP (if possible) and let me know
Upd.: nevermind, I forgot you don't have an sd card,.
Upd.2.: without SD you can try to flash Service ROM (or B361 firmware) using TWRP and sideload method. Unfortunately, sideload is Greek to me , so google it.

Flash TWRP over eRecovery, run command

when a yellow warning appears on the screen, pres and hold Vol Up for 3 sec.
Edit: maybe your data partition is formatted with f2fs (after installing Elite ROM) , it should be ext4. I'm out of ideas bro, sorry.

No problem. I think I hard bricked my phone, I just got boot logo and fastboot but I can't find any fix or solution or anything to do with this.

IMO you only need an SD card and flash the Service ROM.
