Hello,
after a couple of attempts at installing TWRP recovery, some successful, some not, a ROM reinstall and finally this last factory reset, my Huawei P9 phone is stuck at what appears to be boot or restart loop. It is interesting however that I am unable to turn off the phone at all and it's been like this for an hour. At first, TWRP recovery wouldn't boot but the OS would. Then I did factory reset and phone restarted. Since then it won't boot or turn off. When I hold the power button to turn it off, it vibrates once, then vibrates again and then Huawei logo is displayed. After that a message that says "Your device has been unlocked and can't be trusted." & "Your device is booting now..." which is normal since I unlocked my phone bootloader, but the problem is that it is just stuck there.
It stays there forever, screen on, phone on, can't restart because it comes back to the same point, can't turn it off since battery is impossible to take out... Any hope? I bought the phone a couple of days ago and this is really bad... Help!
Edit: In case someone else stumbles upon similar situation - after trying everything possible with these 3 buttons I had available (vol+- and power), I have managed to boot by (I THINK) holding the power button for 10 secs but releasing it really fast after the screen turns off and BEFORE the first vibration happens.
Edit 2: Now I have the same problem again and I can't seem to get the right button "combo" to pass the booting phase like I did some hour ago... Any ideas?
Edit 3: It appears that the ROM I have flashed caused problems with TWRP - after I got an SD card, managed to put stock ROM (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) on it and then did force upgrade, the phone booted successfully.
Step by step:
1) Drained battery to 0% and forced phone to turn off (otherwise it would vibrate twice and get stuck loading TWRP if I tried to turn it off using power button)
2) When I plugged it in and it got some battery power it started, avoided TWRP and regularly booted the OS (which was causing problems with TWRP in my case I think). If you don't have any OS, do not recharge or turn on your phone until you have prepared and put SD card into the phone
3) Downloaded and extracted the dload folder from the P9 stock ROM archive (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) to root directory of SD card
4) Unplugged and turned off the phone using OS Shutdown option
5) Turned it on by holding power, volup and voldown buttons together - "Your device has been unlocked and can't be trusted. Your device is booting now..." message appeared so I thought it was stuck again and was about to hang myself, but then the OS upgrade started (if it doesn't work right away, try restarting the phone with power, volup and voldown buttons held together again)
6) Upgrade was successful but the phone wouldn't boot without complete factory reset, after which it booted normally. Bootloader was relocked, then I updated to the latest stable EMUI (4.1.1) and life returned to normal.

I can access Fastboot&Rescue mode and use abd (but phone is not rooted). Other than that I can't get to repeat what I did when I managed to boot the phone previous time this happened some hours ago... Can anyone post all volume+- and power key combinations which I can try?
Any other ideas more than welcome...
Guys can someone help with this. I'm having the same sort of issues. I have flashed an update and now I have lost touch on the screen. I can't even use twrp because the touch is not working.
Please can someone advise.

After getting an SD card (everything I did so far was using internal storage) and putting stock Huawei P9 ROM on it (Android 6 and EMUI 4), then shutting down (forced by draining battery) and doing force upgrade (vol+ and vol- held after power up) I have managed to (upgrade and) boot my phone and get it back to normal again. If anyone needs more detailed explanation on how I solved this, feel free to ask.
Open bootloader again, i had the same problem few days ago
Yes please vernicht. My touchscreen has stopped responding after flashing an update.app using DC Phoenix.
I really need to get the phone back to normal.
Thanks in advance

Can you boot into OS? Please provide more exact details.
How I got out of the TWRP(?) boot loop: I couldn't take out the battery, but I have managed to drain it to 0% by letting the phone stay on for hours thus eventually shutting itself down. After that I have charged it and then powered it up. It didn't attempt to boot TWRP (no loop) but instead booted back the OS. After that I could regularly restart the phone and do all operations without getting stuck in loop, which allowed me to issue force upgrade command using hardware power up/down buttons.
Nope. I manage to flash it with DC Phoenix fully but it just keeps boot looping and going back to the Huawei logo. Then after that if goes into its recovery menu and the only my to use the menus is with the volume keys.

Are you able to put files on your SD card? If yes, you can try putting stock ROM on it and then force force upgrading (hold vol+ and vol- together after power up). It should overwrite everything and boot up.
I have done this but it won't even force flash the stock rom. It gets to 5% and says 'system error'
I followed your suggestion to let the battery drain and then I charged it fully, but when charging it got to 1% and rebooted the phone into eRecovery.
I wish I could get this phone fixed and back to normal.

Did you use this stock ROM for P9 (if it's EVA-L09 like mine) or something else?
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
It worked fine with force upgrade for me, while some other ROMs didn't.
Do you have Wipe cache and data/factory reset options available in eRecovery, did you try that?
I'll try that. The only problem I have is my touchscreen won't respond under eRecovery. I have to use the volume and power key to navigate. Any idea what's happened there?

It will probably return to function after you restore to stock ROM. Until then you can use power button to select items in eRecovery if needed.
Btw I have edited my original first post in this thread with step by step guide on what I did in my case.
Thank you Vernicht for all your help.
I finally manage to get the phone fully working again. I also managed to get it changed from C900 to C432, lock the bootloader and join the beta.
Thank you so much again. It's very much appreciated.
Merry Christmas too

Hi nscxp2005
how did you manage that?
i have the same Problem.
i have done a "Wipe Cache" and a factory reset.
i have copied the "update.app" from PauloBrien zip on a sd card in a folder named dload.
then i have done a Force flash -> it goes to 5% an says Invalid File.
when i look in the device with DC Phoenix it says it is a EVA-L09C900B136
Why have i done that?
My wive have the EVA-L09C432B136 and i updatet it OTA to Nougat.
i thought i could switch to that version to get the new Nougat but something went wrong......
thanks in advance and sry for my english =)

Hi Guys, hope you can help
I have got an P9 EVA-L09 which I tried to update to B378 but failed and now it stuck in a boot loop and won't recover using the phone.
I have tried to download the update mentioned above and doing a forced recovery on the phone Power + VOL+ + VOL- but no luck, gets 5% and fails.
Would like some help please.
Hello, I have the same problem, I tried to install Lineage 14.1 and it didn't work. Then i tried to go back to EMUI 5.0 and i just all fell apart. No i have no android on my P9 (cos i wiped all data and the system through TWRP 3.1.1.1), and now my touchscreen doesn't work. When i try to force install, it blockes on 5%. Anyone have any idea on how to fix it? Thanks

I have the same issue after flashing the rollback package from the official huawei site. The phone isn't rooted, it just had a branding for some odd reason. So I installed the C432B182 but somehow ended up with a C900B... firmware. So I installed the Rollback package C900B300 using the 3 button method. It said successfull but ever since I've been stuck in the same loop. At the logo. Trying to enter recovery mode (Volume Up + Power) or Force flash any of the firmwares (stock C432.. or rollback C900) doesnt succeed. It wont attempt. Only vibrates as you described and turns the screen off for a second before entering the same loop again.
How did you manage to enter the flash Menu??
Thanks in advance and hope you can help.

Hello!
At me too such problem. When charging to sit at 0% and plug it into the charger, it immediately turns on and goes into the system, then the screen is worth a long logo. I have a phone EVA-L09C627B150.
Help me find my full version! Or I can use this version by reference https://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
Sorry for my English!
Hi guys.
I have a P9 EVA L09C432B378 .
My problem is that my phone is stuck on the animation which takes you to recovery.
That is the only thing that the device can do. It doesnt even go to fastboot and i cant turn it off
Anyone can help me please? I am so nervous and worry
Thank you
What was the last thing that was done that caused this?
What you can do is drain the battery so it turns off, once its off, hold down the volume down button and connect the phone to your computer, this should get you into fastboot, after this you can use something like DC-Phoenix to get it booting up again.
Hey guys,
I really need your help. My P9 (EVA-L09) is bricked. I updated it to EMUI5/Android7 (rooted it) and then did a Rollback (C900B300). That worked, but then I wanted to update it to C900B182 and it got stuck in a bootloop. I tried to hold the Power Button and the Vol- (and Vol+) Button but nothing happens. It just keeps on turning on and off all by itself (the power is now empty so it is turned off but as soon as I plug it in it is charging a few % and turning on and off again). I tried to load another Version on the SD card (dload folder) so the phone may flashes something but that didn't work either.
I don't speak English very well and I'm not that talented with phone- and pc stuff, so if someone knows an easily explained tutorial or something to save my phone I would be so thankfull.
Thanks.
Easiest way is to use DC Phoenix, some one posted a small guide so you can try following that (link below).
https://forum.xda-developers.com/p9/help/unbrick-p9-single-sim-using-dc-phoenix-t3560577
Another thing to consider is that the Vol+ Vol- method does not work well if your battery is empty/low. Maybe try booting into TWRP recovery (the newest version should work for you) and charging the phone before trying again.
so i have an lg optimus l90, and when i try turning it on it stays stuck at the lg boot logo, doesnt move from there, and if its off and i plug it in to charge, it marks 0% battery, then changes to a screen with a loading icon frozen inside of the battery icon, doesnt move from there either, i tried factory resetting the phone, but after confirming that i want to reset the phone, it stays stuck on "Factory Reset Processing..." and doesn't move from there either, i connect it to the usb while its off and while pressing the volume down button, and it enters what seems to be the download mode, but in the codes it says something about fastboot, so im not sure what im doing there... any help would be very much appreciated.
Nobody knows??
Also, I'm trying to upload an image to show what screen appears when trying to enter "Download Mode", I can find the insert image button, but there I can only insert an image from another website, in other words i can only attach a url, doesn't give me the option to upload an image from my computer, and i can't seem to find another option letting me upload the picture either, If anybody can tell me as to what to do with the phone, tell me everthing step by step, because I don't really know much about this, but as long as there are steps I can get things done...
Hello everyone, I saw a few posts on this forum about other bricked phones, but my case is different (if its not then please link me the thread, Thanks).
Story: Today I decided that my unrooted phone wasn't enough for me, so I said: "Why not root?" . I have to add that I owned a LG Magna 3G before this Huawei P8 LIte 2017 and oh boi was the rooting procedure WAY HARDER(the huawei procedure)... I did well with my LG, but not so well with my Huawei. To be honest I was almost done but because I couldnt boot into TWRP, I decided to follow a guide I cant find cause I followed so many that my History is a mess (if anyone requests I will do some digging though). The guy suggested to someone that couldnt boot into TWRP (like me) that he should falsh TWRP>relock his OEM>Shutdown>Press a combination to go into recovery mode>???>Profit. I did just that but my device is now a 180 Euro brick.
Probelm: My device bootloops. Every time I shut it down (hold power key for 10sec), it reboots and gets stuck on the famous "Your device has been locked and can't be trusted. To learn more, BLAH BLAH BLAH. Your device is booting now...
I tried several key combinations, but whatever I do, when I hold my power key for 10sec, The huawei logo pops up for a second or two and then I get stuck on this screen again...
Sadly, I seem to have no connection between my PC and my device (adb can't find any connected device).
I also want to add that, after I was promted to relock my OEM, I removed the USB cable whoopsie.
What Im looking for:
A way to regain contact between my PC (adb) and my phone
A way to shutdown my device for now (and not forever... just for the night)
Someone to tell me that he had the same issue and took the following steps (Need clear answers and steps)
Anything else whatsoever
I don't think it's necessary to provide the files I used, since the reason my device is like this is because of my own stupidity:silly:
Thank you for your time.
You have to hold Power and Volume Up button pressed to boot into erecovery, not only power, check it.

Sorry for replying after 2 hours, I didn't get a notification.
I tried:
1. Holding the buttons until I see the "your device is booting..." message
2.Holding the buttons until it vibrates
3.Holding the buttons until I see the Huawei logo
Thanks for your time anyway
You press Volume Up + Power simultaneously, when you see the Huawei logo you release Power and hold Volume Up only until it boots to erecovery.

The most drastic solution is the DC Phoenix software, not for free, if i am right they ask 15€ for 72 hours.
Not going to bother with this one tho... if I am very desperate, I might try to "borrow" it, but Im gonna seek other solutions until then.
Thanks for your time
On the "your device has been unlocked" hold the Volume up button until you boot to eRecovery. From there connect to wifi and restore stock rom. Afaik, erecovery should boot on bootlooped device. Give it a try
If this doesnt work, plug in to pc, and hold volume up + power, on huawei logo leave power button and hold volume up until you get to erecovery

Hello, thanks for replying
My device is now good, only gapps are missing but I don't care too much. Here is what happened:
So, I left my phone unplugged from any power source during the night (meanwhile the screen couldn't turn off), although I swear I did this 20 times already, when I booted my device after I came back from my University, my phone booted into eRecovery... I downloaded the latest package and it seems to work just fine now, the only problem is that the gapps need to be flased via TWRP (that I don't think I have anymore, how ironic).
Thanks to all of you who cared about giving me a solution :victory: Have a fantastic day
If you want to have a complete working system, i suggest you to try to update using erecovery again. It should download full firmware with gapps etc

Well, that was what we told you to do at first time. Erecovery can bring it back to life easily. Now as you have already been told erecovery flashes the complete firmware, including gapps.
You can also try to update it through the settings menu, in the system update settings you press the three dots menu on the upper right corner and select download latest complete package.
