Huawei P9 Lite Doesn't Open - Huawei P9 Lite Questions & Answers

hi guys i'm using Huawei P9 Lite PRA-LX1 (in europe VNS-L31,i guess)
i installed Elite Rom v2.0 to my phone. sounds are gone.
i had bootloader, twrp and root
after that i installed L31C432B130.zip via update menu(power+volume up+down).
installation completed sucessfully. phone restarted yourself.
after that phone didn't open
i lost my screen, twrp and bootloader menu.
phone doesnt react to my key combinations (power, power+volume up, power+volume up+down vs.. you got it.) i lost my everything. just staying working sdcard in my hand. and a defective phone.
last one when i connect my phone to computer with cable, comes a sound from computer. when disconnect or when i press power key on phone for a long time comes a sound too. still working, charge is full.
All my impressions are that's it. how can i fix it?

Can you get to fastboot ? ( connect the cable to the pc not connected to the phone yet , then when you insert micro usb into phone , hold volume down button )

I don't know the screen isn't the problem. Try to flash boot image etc now

I have your same model. Your device has bricked because you've forgotten to flash the oeminfo before flashing .zip .
Now, you have to enter fastboot and try to flash the twrp 3.1, that support Nougat, then flash the oeminfo. If you cannot, unlock your bootloader again. You can also try to flash oeminfo using the toolkit, but it's more difficult, because you can't open your phone.
Flashed oeminfo, update your phone with the stock b150-b160 UPDATE.APP using dload method.
Reboot and enjoy.
Warning: flashing oeminfo will relock your bootloader

Try other recovery, because is the easiest way. Have you tried Revolution recovery? It works with no os.

See if your nokia driver is installed correctly.
Can you see your device in device manager while its connected to pc in fastboot mode?
Did you successfully flash the recovery via fastboot command?
How long did you wait for your phone to boot into recovery? sometime it takes a little more time to goto recovery.
if the drivers are installed and recovery is flashed then it must goto recovery. I had tested this method on my own phone and its working fine.

I can flash twrp but can't boot into it. One stupidious thing I did was I rebooted my phone when the dload update showed up but it was stuck at 5%.
EDIT:I fastbooted the boot,system,cust and recovery from the B523 firmware but now it's stuck at Huawei logo.
Go to erecovery and factory reset.
Volume up + power.
Tried it. There's no factory reset option in erecovery.

Why do we have 2 recovery in each firmware?
And how to flash the second recovery with fastboot?
To enter TWRP unplug your phone, press Vol UP and then Power, wait til it vibrated 2x , then when you see the huawei logo, release both and wait

First of all, thanks for your reply.
I tried what you told and the stock recovery comes up with the software install failed thing. No matter , How many times I flash twrp, the stock recovery comes up. I tried placing the B380 UPDATE.APP in the dload folder of the sdcard. Tried the same thing with nougat UPDATE.APP. Both times it says software install failed.
Did factory reset again and ahter the message your device is booting, the screen goes blank but stays on.
@gm007, I tried the stock recovery you posted but same result. How come I don't have factory reset? Does it has something to do with being unlocked.
EDITkay, by luck or something I got the WIPE data and cache option. I did both of them, But now it's stuck at your device is booting now.
If you were in EMUI 5.0, welcome to the club, until today I could not revert to 4.1 or 4.0, all I could do was make 5.0 usable. If so, you will have to use the boot, recovery, recovery2 and emui 5.0 system on the fastboot and then use the dload with the rom that "attached" your phone. I'm on AL10C17B523 and I can not reverse it at all, I've already accepted my burden.

If TWRP for EMUI 5 arrives then we can do something.
So is there something I can do? I copied the UPDATE.APP file of B552 firmware into the dload folder of the sd card and Did the dload update thing. It says incompatible software - installation failed. I think I can fix this, Just need some instructions.
I successfully downgraded to Kangvip b368. The procedure was as follows
First of all make sure you have nougat stock recovery .
Then download stock B320 , extract the update.app and put in the dload folder on the sd card.
Next do the dload update by pressing the 3 buttons.
Hopefully it will complete to 100%
After that do a factory reset. U may find that your bootloader is locked again. So unlock it, flash twrp and u r good to go. Flash Kangvip b368 through twrp and that's it.
Kindly Mark this thread as solved.

P10 black screen bricked!!

I tried to flash a custom rom (MorfuZ) and after installation is complete, the phone reboot and stucked on black screen. I can't get to fastbook or recovery screen. The MultiTool software recognises the device. I tried flashing trough the ''Unbrick'' method and it seems the process is completed, but the phone won't boot. I tried to turn it up but even the screen is not turned on. I have no red or green led as the others threads says (yes I've read a lot of them). The only sign of life is that my PC detects it as "Fastboot2.0" and it's supposed that I flash cust, boot, system and recovery imgs but nothing happens at all. It sounds it's rebooting and the cmd also says that but there is no change. My phone is LATAM version (WAS-LX3). Already bootloader unlocked, installed TWRP and rooted (magisk). My laptop recognises the device the (prompts sounds when connected.)
I tried flashing boot, recovery, system from this .zip file Warsaw-L23_C605B172_Firmware_Panama_Bolivia_Peru_Chile_Colombia_Guatemala_El Salvador_Nicaragua_Honduras_Nonspecific_Android7.0_EMUI5.1_0501 but I couldn't find the CUST file to flash with Multitool software.

If You still have TWRP and if you are on Emui 8 use HWOTA8 method, otherwise if you are on Emui 5 use HWOTA7 to flash your build. As you have already unlocked bootloader the first step in script will be automatically skipped.
Its very easy just follow my video tutorial. Instruction for HWOTA7 is on Serbian but you have instruction on English and some things are logical just view video.

Yes I understand u must use DC phoenix and test point method after that Hcu client to restore Imei, seriall. Dc phoenix and Hcu client are about 20 usd credit for 3 days. But for test point u must open the cover and on board find test point, conect it, plug usb and run Dc phoenix to restore all partitions. Its not so easy but phone could be fixed.

Axon 7 not able to install TWRP or lock bootloader

Hello all,
I need help with my Axon 7 (A2017G)
I upgraded my phone to Oreo 8.1 (AospExtended), played with it a bit, but decided to downgrade to 7.1.1 (stock) again.
After I did so, I noticed something different. Firstly when it boots up, this screen appears
{
"lightbox_close": "Close",
"lightbox_next": "Next",

}
It goes away after 5 seconds and boots or if I click the vol up or down button, it takes me to this screen
If I choose anything other than Recovery, the phone just boots up
If I choose Recovery, it takes me here
I cannot boot into recovery mode at all. I can't find out how to install TWRP recovery on here at all.
Also If i boot using power+vol down, this appears
Please advise how to install TWRP and lock the bootloader
Have you tried the Axon 7 tool by Djkuz?
It should be able to get you out of this, I'll find the link for you.

that is, like, 100% normal. you have stock recovery and that FTM mode just gives you adb. If you can't enter fastboot then you would have to install it via EDL.
But before doing that, why the heck would you want to lock the bootloader? Lol you can just hide the 5 sec screen and sell it (or return to zte, they never check), there's no difference at all
If you're gonna lock anyways, you have to install TWRP via EDL (use EDL Tool by djkuz) then install the "remove inscription" by raystef66 or follow the steps on his guide. Then you will get fastboot. After you do that, just reboot the phone. TWRP should be replaced with stock recovery again. Check if it was (power + vol+) and if you enter stock recovery then go to Fastboot (via "adb reboot bootloader") and do the command to lock
Of course you have to be FULLY stock (no magisk or whatever) or you'll brick your device

Mi A1 Bootloop after ota update and Locked Bootloader

Hi,
I've installed an ota update and the device didn't boot... it is stuck in a bootloop....
When i try to flash via fastboot, it appears an error saying that the device is locked ant cennot erase...
via fastboot oem unlock i get the error message: Remote: oem unlock is not allowed
via MiUnlocker the unlock gets to de 50% and gives an error and on its logs it says: Remote: oem unlock is not allowed
I tryed to flash TWRP with command fastboot flash recovery but the error is the same: remote: partition flashing is not allowed
Can anyone help me please??
I'm stuck on the bootloop i can't go to setting - developer - allow oem unlock option!!
Have you tried doing a Factory Reset from stock recovery?
This is a strange behavior, even if an OTA update corrupted the system for some reason, the phone should boot from the original slot.
Have you tried switching slots manually from fastboot ?

You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

Actually you have a recovery. You need to long press the power button and, afterwards (not at the same time), press the volume + button. You'll see that all options will appear.
