Huawei P8 Lite ALE - LO2 not powering on

Hi guys, I'm from South Africa and I really need help right here!
After updating (not manually) my Huawei P8 Lite ALE-LO2 to android 6.0 it was working perfectly. A few days ago the phone started freezing and powering off, when I try powering the phone on it just flashes a red and green LED light and doesn't switch on, sometimes it does switch on but freezes on the Huawei logo. When I plug it in a charger it still flashes red and green light. Sometimes it would take me to rescue mode and says I need to re-update the system. The problem is I can't power it on, and therefore I can't do anything on the device.
Your help will be highly appreciated.

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?

P9 Lite not turning on (Stock system)

Hi all,
I have been using my p9 lite for almost under a year. Last night I factory reseted my handset. After a successful restart and configuring all the initial settings the phone asked for a restart again but afterwards the phone couldn't boot up. Before the final restart the battery level was 55 Percent. Now the battery status shows zero. I left it charging overnight the battery status shows 100 percent but when I try to turn it on the service light blinks red few times and after a slight vibration the phone is unresponsive. Not even Huawei logo shows up after the vibration.
I cant even boot into recovery mode.
My Oem and bootloader is locked as I am on stock system.
I am able to get into fastboot but I think thats not helpful as the bootloader is locked.
The phone is single sim variant : VNS-L21
Updates: So, I went to Huawei Center, the phone is not in warranty anymore. I opened up the phone to try to remove the battery and reconnect and then boot into recovery mode but still no change in the situation.
Please help me out. Thanks

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
