Thanks for your comments.No Mr.WoW. It doesn't show anything. but I can volume up and down and even answer a call by dragging on the screen.
I read somewhere I should increase the light of screen by going to it's setting in menu but I can find it in the dark. or I should increase it's light by attaching LCD to another same device but I don't find a same device. even that solution was not useful for other users.
is it a hardware problem? I mean maybe one of it's IC's has been damaged or something like that.

help needed: auto restarts / no bootloader

hello!
Can anyone help me with this:
after 5 or 10 minutes, or even at the splash screen, my device automatically restarts and does it for several times.
When i try to put it into bootloader mode i see usb,..... but only for a minute. after that it goes out of bootloader mode and starts the OS again...
So i'm a bit worried that when i flash it, the bootloader mode will go out and the device will try to restart.
Any known sollutions to this problem? Any help would be appreciated!!
ps: no answers in the wiki nor in the forum.
thanks in advance to your replies!!!!!

didn't work.....
i'm almost sure it is a software issue... I just got it back 2 weeks ago from the repair centre and i got all new hardware....
I started flashing it because the bastards repaired it and putted on a French ROM and an AZERTY keyboard.... i can send it back but i don't want to miss my precious phone another 6 weeks
if i get it fixed now, i stop "messing" with it ;-)
Hehe...
I sent it back to the repair shop. They can fix it since bootloader mode also restarts it must be a hardware problem...
Last time they sent it back with AZERTY and French ROM so they can fix that to!!
Thx anyway for replying!

[Q] jiake jk12 white screen, please help

hey!
I have jiake jk12, last week, for no reason my screen goes negative, after some time it become white and then normal, and again white...
Right now it's just white.
I tried to get in recovery mode or something else but the screen still white so I don't really know if I succeed to get in the recovery mode...
From what I know, negative screen can't be hardware problem so the only thing left to do is to install new rom.
I tried to install new rom (from needrom) with Flash Tool but I think the Flash tool can't catch the phone.
When I connect the phone I hear that sound of new device connected and after some seconds the sound of the disconnected, and after another few second the Flash Tool goes 'not responsive' for a couple of seconds and then nothing...
Any suggestions?
Thank you!
You'll have to replace the Display Screen... That's what I can figure out right Now...
Press Thanks if it helped!

I believe it isn't hardware problem because that before the screen become white it was negative, and negative can't be caused by hardware problem.
Can somebody help me?
I really don't know what to do...
Why I can't install new rom?
What am I missing?
Someone, please??

Display won't turn off

Since the last update 389, my display won't turn itself of after leaving it on. I need to manually push the on/off button to make sure it gets turned off. Hoping to not have to reset the phone, so any suggestions on how to correct this error is appreciated!
Thanks in advance!

most probably reset would fix that

Check your screen timeout.

Hi Ricky , am sure u might have set screen timeout to never or +30 minutes . Kindly check it and then done
Hi,
Screen timeout is set to 1 min and even if I change it to something else screen still won't turn off by itself.
I'll guess I will have to do a factory reset.
Thanks for all replies!

Honor 8 screen upside down and reversed

Hello everyone!
I dont know if someone already posted this thread, but I'm a bit desperate now. Here is my problem.
A few days ago I was sliding through Facebook, when my phone screen just turned upside down and backwards.
1) Restarted the phone - NOTHING.
2) Rooted and tried to modify a line in system folder (rotation) that everyone said would solve the problem, but the line doesn't eve exist.
3) Factory reset and flashed stock firmware- NOTHING.
4) Tried updating screen firmware through MMI/USSD code, but phone refuses to execute codes.
Rtl layout is not on just so we're clear.
Screenshot is normal. The controls are the same, but the picture is upside down, so I would'nt say it's a hardware problem.
Any suggestions before I replace the damn screen?

That is kind of weird, unfortunately I have nothing to advice that you didn't perform previously , I think the best thing to do is to send it to customer service :/
In my opinion it is a software issue and changing the screen won't resolve it
Weird.
Is it revered in fastboot or recovery too?
This would highlight if it's a screen issue or ROM software...

Give it a try flashing another firmware via dload... May that could help..
Ok, we have a brealthrough! I flashed a few new firmwares, and when I flashed the last one the picture went to normal orientation, but now the screen is flickering and blinking and going bananas.

LOL.. those are really strange issues.. :laugh:
Downgrade your phone to marshmellow.. Try flashing marshmallow firmware.. If it went back to normal upgrade to nougat via OTA.
Holy crap it's back to normal. I went to developer options and disabled HW overlay. Apparently CPU and GPU were ''fighting'' over who's going to control the screen. So for anyone who has the same issue as me, and none of the solutions I mentioned in the first post help- flash stock firmaware/firmwares, and if the problem persists, disable HW overlay. Thanks a lot guys
EDIT - Oh and flashing firmware via dload worked like a charm. Thanks hassanjavaid8181
