Huawei P9 Lite stuck on bootloop, can't enter recovery mode

Hello, I'm new to xda, in fact I registered just to ask for help. My p9 lite got stuck on huawei logo, when i try to turn off the device it just reboots 2 times and then just stays on huawei logo. I can enter fastboot and rescue mode, but i have not enabled usb debugging and oem unlock on the device earlier. To be honest this is my first android device, in the past i used only windows phones, so you could say i'm completely new to this. Any suggestions on how to recover my phone or flash any rom into it? I'd be very glad if someone helped me find the solution to this problem. Not sure if i made a thread in the correct place, direct me if i'm mistaken

There are few different versions of P9 Lite, look at the back of the phone to the bottom to see the numbers beside VSN and let us know.
1) Also when the phone is turned off plug in the usb to a computer or charging adapter
2) Hold down volume up & power
3) Let go of the power button when you feel the buzz while still holding the volume up button
4) Download latest version & recovery.
5) Go to Settings>Developer Options>USB Debugging On
5B) If you don't see Developer Options in settings, then go to Settings>About Phone>Build Number & ( tap the Build Number untill it unlocks)
6) Update us on the status, hope it works out.

tried to enter recovery, still not work. can't go to developer options because phone is stuck on logo, can't power off. couldn't find any solution that works anywhere, been searching for more than 6 hours, still no use. phone model is VNS-L21 forgot to mention earlier

What exactly were you doing before this happened and does your computer recognize your phone when plugged in at all.
Try holding volume up & down together & plug phone in when it reboots on you, & report back with what you see. If anything at all.

I tried to install nougat update, computer recognizes it only in fastboot. holding volume buttons haven't changed anything still no progress. the thing is i had installed nougat a moth or so ago and it worked fine, then rolled back to marshmallow and now this. i'm pretty sure i tried to install correct package, because it was the same i had installed earlier

Did you download a adb tool on your computer that have the 'fastboot.exe' file? If so open that folder,
Have the mouse curser hover in that folder, hold down shift & right click the mouse
Open command prompt
Connect phone as is in fastboot mode
Type adb devices & press enter
Type adb continue & press enter

Hi,
I have the same issue as ellanyx.
my phone can only be stucked while booting or if I connect my phone to a computer, I'm able to boot it in fastboot.
as ellanyx, I didn't enable usb-debug nor OEM unlock option...
so when I'm in fastboot, I type the command "fastboot oem unlock xxxxxx" (hopefully the different data needed are the correct ones mentioned on the box of the phone) I get this error message:
C:\Users\Dieu\Downloads\SRKToolHuawei-STABLE-V1.3-20160619>fastboot oem unlock xxxxx
...
FAILED (remote: Command not allowed)
finished. total time: 0.016s
and off course the other options like "fastboot flash recovery recovery.img "... doesn't work.
I can't use the adb commands neither.
when I type the commande, as mentioned above, "adb devices" or "adb continue", nothing works.
So I'm a bit desesperate
do you have any solution for this kind of issue?
thanks

Dude, so the last firmware on your phone was MM or N? If it was MM you should put stock firmware appropriate for your model in dload folder on SD card and put volume+volume-power, and thats it. If you stack on N,....then I dont know because dload method doesnt work with N, or maybe works if you can find stock firmware with recovery for N.
Regards

Unfortunately I can't update with the 3 button update otherwise it would indeed solvemy problem.

Probably you didnt have correct Oeminfo for MM if dload method didnt work....Try to conect phone with Toolkit and follow procedure for flashing oeminfo and custombin, after that flash stock recovrry and b161 via dload metod. You will find it on forum here.
Regards

the procedure from SRK toolkit?
would it be possible to provide it? because I can't unlock the OEM and I didn't tick the USB debug think.

Maybe problem with the ps not phone so u can not connect with adb
Try with different pc you must have flash oem with fast boot without enable adb from phone if u in fastboot

I can only boot my phone in fastboot (vol- + power) and not in recovery (vol+ + power).
also when using the SRK toolkit, the first screen tells me to be sure that the usb debugging is enable, which I haven't done...
if I'm not mistaken, fastboot is to use the fastboot command and recovery the adb commands
the connection with fastboot works on my computer, the link is made. however when I type the command to unlock the OEM, I get an error stating that the command is not allowed.
when I use the SRK toolkit, with the different questions, he tries to connect the phone with adb and waiting.... waiting...
is there a command to reboot in recovery but from fastboot? in the otherway around it exists but it doesn't seem that from fastboot to recovery it exists.
thanks.

dload method works on N. I downgraded my phone from unofficial N update back to official MM update using this method yesterday. You just have to enable OEM at developer options on settings.

It looks like people can't be bothered to read the 1st post properly before they reply.
HE CAN NOT BOOT TO ANDROID SO HE CAN NOT ENABLE OEM OR ACTIVATE USB DEBUGGING!!!!
What he CAN do, is go into eRecovery and Fastboot.
With that in mind, I would suggest using the dload method through fastboot.
Also, make sure it is Huawei SRK Tools 2.0 that is used, as it actually asks if you are in debug mode or fastboot.
Note that there is a few bugs in SRK 2.0:
The TWRP recovery file has the wrong filename in the package, so it WILL fail unless you name it correctly.
Also, when trying to root, do NOT use the "P9 Lite" method as that WILL fail too. Use the "P9/P9 Plus" method.
I am trying to set up a complete guide that can restore the phone when it is stuck in fastboot, however I apparently went a step too far...

Boot into fastboot mode and flash a custom recovery by meticulus. Link : meticulus.co.vu
Then whenyou get stuck hold power and vol down button for 2 minutes the phone will reboot and then when it says that your device has been unlocked and cant be trusted then only press vol up key ( dont press power button then). The u get into huawei recovery. From that u should power off the phone. Now get a custom rom by meticulus into your device sd card ( Cyanogenmod 13 is recommended ). Then insert sd card in a powered off phone. Now press vol up and power key and flash gapps and custom rom and you are good to go.

So, MY question:
I have tried 4 times to get Nougat installed, but every time I got the SMALL package (1.25gb) which means it is not complete.
I decided to try ONE more time, but think I have made a serious mistake.
I was on B161 and tried to downgrade to B160 without upgrading to Nougat first.
This has caused my phone to be stuck at boot with the message "Your device is booting now..."
I can NOT get into eRecovery or fastboot no matter what I do.
If I just leave the phone, then it discharge very fast, but as soon as I plug it in, it starts up and gets stuck at the same screen again.
Does anyone have ANY idea about how I can get out of this problem?
UPDATE:
I have managed to boot to fastboot while connected to my pc.
The phone is unlocked but FRP is LOCKED, which means I can't flash anything.
I read about using Miracle Loader to remove the FRP lock, but it can't "see" my phone. Maybe I am doing it wrong?

Try to relock and then unlock the bootloader again. And make sure oem unlocking is enabled in dev options

Please read my previous post again
I can NOT boot normally. And as FRP is locked, then I can't relock or unlock the bootloader.

Huawei p9 lite bricked, no fastboot, unlocked and stucked on boot....

Hello,
I am from Greece and Ive bought from Vodafone a Huawei P9 lite vns-l21 before one month. Ive installed the nougat rom 370 with firmware finder but I made a mistake choozing the NRD-90M test key. So I begun to roll back to Marshmallow. Everything ok. Then Itried to install an other rom from firmware finder(i think C432b371) and again NRD-90M test key...
Again roll back to Marshmallow...so in the first step when i was trying to install with dload method the Huawei P9 Lite Rollback Package For L21C432 (EU) my phone stucked on boot loop but I had fastboot. Then I have unlocked the bootloader to see if there is anything that i can do with srk tool and now i have a beautifull bricked phone stuck :
"Your device has been unlocked and can't be trusted.
you device is booting now"
In this point nothing happens, I can not go to fast boot, No recovery mode, The hardware keys not doing anything, only resetting the phone in loop..
I dont know what to do and Huawei wants 215euro to fix my phone.
My mistake I know but is there enything that i can do know? Its a new phone!
Sorry for my english

I would suggest getting an sdcard and creating a dload folder inside, then putting an official rom UPDATE.APP file inside the dload folder and try 3button method

As far as I understand, you can't even power off your device which is a problem since the 3button method won't work if you can't power off the device.

Hmm I dont get why they want 215 euro to exchange the storage chip.
I guess your phone is pretty much a brick now have fun. Lol sry

I had a similar problem with the boot-loop.
Press PowerOff until the screen goes black, and then immediately leave power-off and press Power Off + Volume Up for ever until the phone boots normally.
That's what I did and worked for me.

Can you boot to fastboot, if you can you can recover it with DC-Phoenix tool.

No he cant, I have the same problem. Cant fastboot, adb or 3 button method. Even tried unplugging battery then doing 3 button method.

Anyone sopve this problem with no fastboot no recovery no 3 buttons mode?

try to drain the battery, keep screen on, or keep phone on until battery is 0%, you can't turn it on . keep volume down and power pressed, plug usb to pc , if you're lucky fastboot could be ok

Hi there, I also managed to brick my P9Lite - no recovery, no fastboot. After draining the battery completly the phone starts fine but I can't install system updates. I guess I have to live with that. Unfortunately I can't activate bluetooth. Does anyone has an idea how to get bluetooth working again?

idk for your BT issue , but did you try Firmware Finder for Huawei ? easy to use, you will probably able to dl an update. don't use "small " package OTA, use full firmware, about1.6 or 1.8 Go, may could fix your BT.

didn't work out as Firmware Finder is only another way to find a firmware but not another way to install the firmware...

Hello guys,
sorry if i write this but i think necessary to grab best helps..
Try to describe problem in detail (ex. - i was upgrading/downgrading from..........to............ firmware and it bricks, etc...)
Your latest working phone/system/firmware (ex. - mine was VNS-L31C432B381-before i upgraded to EliteRom).
Some information changes according to the country / region of the world in which you live,
so they are useful for those who help you to redirect to the correct thread / give right suggestions...
All the best guyz

didn't work out as Firmware Finder is only another way to find a firmware but not another way to install the firmware...
Yes , a way to get last firmware, or firmware you want through the huawei update app. Without firmware finder ,no way to " force" huawei update app to install anything you want on your device

Sorry for the late response, I'm reading the thread right now. Firmware Finder can also be used to install firmware through eRecovery. Install Firmware Finder for Windows: http://pro-teammt.ru/projects/hwff/v2/GetLatestVersion.action
You need to write down your existing and change both DNS addresses in your router to: 81.177.139.39
You also need to deactivate IPv6 protocol.
Open FirmwareFinderRewrite.exe, go to "common base" and search VNS-LXXCXXX (Your model and customization). Copy the link in "changelog" not of the newest, but of the 2nd or 3rd youngest firmware. Check if it has been approved by pasting the link under the tab with the checkmark (5th position counting from left). If the response is "This firmware was approved to install" you are ready to go.
Copy the same link in the proxy field (the cloud symbol, 4th position counting from left). Click on "set" and "register update".
Now switch off your phone, press "Vol+" and simultaneously connect it to the PC. You enter eRecovery now. Tap on "Download latest version and recovery". Your phone should start the download now, after a couple percent you can reset your router settings, the download will continue. If all is well, the firmware will then be installed.

I bricked my p8 Lite by accident. Please help!

Hi,
I bricked my Huawei P8 Lite by accident when I tried to root it after unlocking bootloader. I can't post links here yet but I followed Rootjunky.com's Youtube video "How to Root the Huawei P8 Lite Android phone" and while I was in the process of installing SuperSU it froze on the logo startup screen and won't go past it. People say in the comments that this happens with the 6.0 version but I'm not sure what I have. I've tried rebooting using power button plus down and can get to the recovery mode screen and hit "eRecovery" but it won't connect with the wifi.
Is there any way I can solve this? I am desperate! I have the "Minimal ADB and Fastboot" program on my PC. Is there something I can do from the fastboot screen on the phone?
Help please!

Hey, thanks, but I'm not sure on how to do this. I don't have much experience with the technical side of this and I'm not really sure how to go about doing what you suggest here. Do you mean put the downloads on the sd-card on my phone? My phone don't show up on my pc since it gets stuck in start-up mode so how would I do that?
Thanks for your patience with an imbecille!

Here you have a really nice guide with links etc https://huaweifirmware.com/huawei-p8-lite/
Make sure to label the folders correctly. Use an adapter or another phone to connect microsdcard to your computer Try to use the second, marshmallow part. if ot doesnt work try two other methods. Choose files accordingly (single sim or dual sim) Hope you will fix your phone

Phew! Okay, so I got it to work! For anyone out there with the same problem, I got it to work by entering the fastboot screen on the phone by holding down the power button plus the volume down button, connecting it to my PC and then using the command prompt program 'Minimal ADB and Fastboot' to flash the files BOOT.img, RECOVERY.img and SYSTEM.img (using the command "fastboot flash boot filename FILENAME.img") that I got from Huawei's official UPDATE.app file and extracted with Huawei Update Extractor.
I didn't know what Firmware build to get so I got the B630 Android Marshmallow 6.0 for my model ALE-L21 (Dual SIM). It worked, but can anyone tell me if this is the right build, and how do I know which one is the right one if I can't access the old info on my phone? Is it even the latest one? I'm in Europe.

HIFI Image Security Verify Error

Hello,
I have a Huawei P8 Lite (ALE-L21) phone with this error: FUNC 8 : HIFI Image, Error 1 Security Verify failed. I think I have tried everything to fix it but had no success, hence why I have decided to create this thread.
As you can figure out, the phone does not turn on, it only shows the huawei logo and shuts down. When pressing VOLUME UP + DOWN and POWER button, it used to show the HIFI image error screen, however when I press the key combination now, it only shows a red screen and turns off. I am able to enter fastboot and rescue mode by holding down the VOLUME DOWN button and plugging in a USB cable to the phone from a computer. Apart from that, I can't do anything else with the phone. (I do not have any software related to the phone installed (HiSuite), no backups, no nothing because the phone actually isn't mine and I have never actually played with it and androids in general.)

Recovery mode using HiSuite - "Your device is not supported for system recovery"
I have tried flashing different ROM's using fastboot - when I try flashing it says "FAILED - command not allowed", which I assume is beacuse the bootloader is locked?
installing a ROM using a SD card (Force update or something) - the red screen shows and the phone shuts down
Huawei Update Extractor - updating specific files e.g. boot.img, still not allowed to flash
TWRP - the same error ( not allowed )
Rollback to the previous versions using fastboot - not allowed
At some point I was able to wipe the cache on the phone, not sure if that matters anyhow.
When I am in the fastboot & rescue mode, there is a text in green saying "Phone LOCKED", which I assume means that the bootloader is locked? So, I was trying to get the bootloader unlocked, however found no success. I have also tried emailing Huawei support to get the bootloader code, however as you may know, they did not want to provide the code.
I was able to extract some information from the phone though, using these commands: https://forum.xda-developers.com/showpost.php?p=70483520&postcount=2
To get the bootloader code I have tried:
dc-unlocker - I think you need a working phone and have usb drivers installed for this to work and also I think you have to pay for this service
Kingroot + fastboot - https://forum.xda-developers.com/p8lite/general/alternative-method-unlocking-bootloader-t3799294

Does anyone have any suggestions on how to resolve the problem, or is it unsolvable? I would prefer to do it myself and not send the phone to Huawei or whoever as I would like to spend the least money possible. Also the warranty is long gone, since the phone has been bought in 2015.
