P8 Lite won't turn on after MM update

Hi there
I've just replaced the screen of my P8 lite. I booted, everything working fine in Lollipop. so i start downloading the update to 6.0 via the updater app.
it just casually installed the update, went to the screen with percentage of how far the update is at. It finished, 100% then decides to reboot and poof, only black screen, no boot up screen or all the other stuff. Just a plain Black LED Backlight.
I've tried downloading the 6.0 to 5.0 firmware on my sdcard in dload map. when i boot the phone by holding volume +, volume - and power button, it just boots back in the black screen, not starting the update.
I've also tried other firmware the site offers.
Here is some information about my device:
Huawei P8 lite ALE-L21
Which steps should i consider taking here?
thanks in advance
Update: apparently it's just some problems with the hardware of the screen, since when i press volume +,- buttons it still makes sounds, and double tap takes a photo. But isn't it still quiet strange that right when the update hits 100% it started malfunctioning?

urgent help! oppo a37f

Hello people on Xda! I just bought a oppo a37f and it's was working okay until I turned it off, when I turned it off it just kept on going to bootloop. So I flashed many official firmwares using the Qualcomm tools and also the official tool for oppo. But everytime I flash sometimes it will come up with the setup screen everything works until 3 mins later it lags and sometimes have a black screen so then I force restart it (volume down + power) then it's the same again bootloop. I've really tried all possibilities that I could think of and hours and hours of researching on how to fix this. And I don't want this phone to go to waste.
So if you know how to fix this kind of problem then any advice would be good

Maybe it's a hardware issue

N910F Boot loop

Hi
I am stuck with Pulsing blue LED and the "Powered by Android" screen,
have access to both the recovery and the download Mode,
I also have Odin (version 3.13) on my computer along with TWRP (3.1.1 trlte and 3.2.1 version)
My device is a Samsung Galaxy Note 4 N910F bought in shop, no special carrier. It was bought in the Netherlands.
I have tried everything that I have read. The furthest that I can go is the Second Samsung Logo with the Flashing Light
Whenever I try to Flash the stock Firmware for my N910F, everything goes well in Odin but then when the phone reboots, it (sometimes) install the system update until 30% then shows erasing then either crashes right there and then or load the system update bar, completes it then shuts down.
I have tried multiple firmwares, even recovery firmwares. All the same problem. I can see the firmware is flashed, because when I enter recovery mode after I flashed a different ROM, it shows the version I flashed.
I cannot seem to install TWRP because it was never rooted.
Whatever I do, at some point, my phone either gets stuck in a bootloop, freezes with the LED light or shuts down.
And I have also proceeded to use different batteries.
Do you have any options?
Thank you

Heat????
I'm far from an expert here, but I've just experienced a similar problem where my N910F started boot looping / freezing within 15s to 2 min after unlocking. Unfortunately my micro Sd (SanDisk 256GB) was corrupted a week ago, so before doing anything else I did some research (XDA/YouTube) and probably found pretty much what you've found. I frequently change batteries so I could discount that as an issue. Someone suggested using the Samsung Smart switch here https://www.samsung.com/uk/getting-started/smart-switch/, but I haven't used it (yet) so I can't tell. I presume you had the latest firmware from Sams https://www.sammobile.com/firmwares/galaxy-note4/SM-N910F/.
My issue was that I needed to recover data, docs, photos, phone numbers etc. When boot looping the note 4 got very hot . In particular around and to the left of the camera (looking at the rear). Thinking it could possibly be the dreaded eMMC problem which also manifests itself by creating heat, I thought cooling the device might help. I placed the Note on a cooler box freezing block and voilà! No boot loop. I was able to remove all, but necessary apps and do a full copy to my PC. Storage was reduced from around 90% to 50% and memory 80% to 60%. It's now been stable for 12 hours, but the jury is still out. Next will be full reset with he latest available firmware 6.0.1 as mine was still on 5.1.1.
Good luck and hope this may be of some help.

I've got this problem, too, when using the unofficial Lineage 15.1 rom. SIM death and boot loop. After flashing the latest stock rom through odin, it passed but the screen was black and no system was installed. The blue notification light was constantly stuttering, though. And I couldn't even go to recovery!

When flashing, a 910F can get hot - use a cool temperature room and/or a fan blowing onto the device.
If it's not too late...

hi, do you dolve your problme? i guess i have the same problem XD
regards

My P10 plus started this exact problem today. Always stock, never rooted or boot unlocked.
I was playing a game and it rebooted. Started again and lasted a minute but then constant bootloop to eRecovery screen.
Did the erecovery image download and didn't do anything brought me back to the same screen
Tried to factory reset on the ecovery screen and then booted, but during setup it rebooted.
Went to fastboot screen (pwr+vol down while attached to usb) and rebooted after. I was able to go through setup.
After letting it for sit for only 2 minutes as I type this message, it randomly started rebooting on its own.....and now back to recovery screen.
FACKKKKKKK

UPDATE: Took my phone in to a cell repair shop after exhausting all my troubleshooting options.
They said they took the phone apart to disconnect the battery and do a full power drain. Then after reconnected they installed EMUI 9.1 again via USB and got the phone up and running.
Been working for me for the past 6 hours, but the phone just rebooted on me once, so i'm sure they're still an unsolved demon in it. but no idea what it is right now.... May be time to start phone shopping.

maybe just battery broken, install app accu battery or any other to check batery

P8 lite l21 black screen

Hello everyone,
Yesterday I got my hands on an old Huawei P8 lite, it was working fine but I intended to root it and play with it a lil bit. The phone was running android 6.0 and I needed to rollback to 5.0. I flashed the rollback ROM without any problem, but then I went to flash the B170 ROM and after it was done, the phone's screen won't show anything. I can see the backlight turning on, and the phone is responsive, since it vibrates whenever I try to turn it on (the boot sound also plays) and the LED turns on whenever it's charging. However, the screen shows nothing but black. The boot logo won't show either. I'm afraid the LCD screen was damaged, but the phone didn't really suffer any kind of physical damage... it happened right after flashing the B170 ROM.
Does anyone have any tips? I've tried to boot the phone either on recovery mode or fastboot, but the screen it's still black, so I can just assume it's booting on that mode even if it doesn't show anything.
Thanks in advance
