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:

Click to expand...
Click to collapse
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
fastboot flash CUST cust.img
Try to use this commands as i write with capitals

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

P9 Lite cannot flash stock firmware

I have a Huawei P9 lite. (VNS-L31 dual sim) . I tried to install medrom 3 and after flashing, phone didn't boot up. So I flashed b161 firmware again using 3 button method and phone booted up. Then I realized I couldn't add my google account. After searching on xda I found a method to fix that.(flashing oem info ). But after doing that, when the phone boots up after the huawei logo the error message which says "your device has been unlocked" has become red.( Usually it's yellow). And in about phone my model number has been changed to something like hi6250 or hi650.( Can't remember the exact thing). Then I tried to reflash my b161 firmware using 3 button menu and voila. It says incompatible version. I can't flash it. Then I replaced my build prop with my friend's phone's build prop. But unfortunately it has the B151 version. Though I have B161 version installed, my about phone says it has B151 version. And I can't flash stock firmware using twrp or dload method od any how. Please help

That's normal if the message is red, it means that the bootloader Will be relocked.
Now for the build prop, download b161 version, use huawei firmware extractor , extract boot.img system.img and cust.img
And by fastboot type :
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot reboot
And voila, b161 is installed in your phone !

If fastboot say "FAILED (remote: Command not allowed)", its because your bootlaoder is locked, reunlock it !

In TWRP it says unable to mount Data :/

Unable to read/mount data says your encryption key got changed by something, whatever. You need to Wipe Internal storage and flash twrp again ( I recomment matic`s ) Reboot to recovery again, if you got one, flash a flashable fw via twrp. I Dont know if the stock recovery Accepts a fully wiped intern storage, i guess not and it declines the update.app method.
In the best case for sure you recover an older backup to get the Same enc. Key back

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.

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

P9 Lite bricked (L31)

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

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?

How do you format the system and restore with a different firmware?

Formatted in fastboot then went erecovery.
