[Q] Help Going fully stock from KK - Urgent

Hey guys.
I've been a long time lurker and finally am needing some help here.
I'm selling off my Huawei P6 and would like to get it back to stock fully rather urgently but there's a few little issues which I know I'm just not thinking straight to solve.
I've gone from KK back to 4.2.2, I've flashed back stock recovery and redid B125/B111. I then downloaded stock from Huawei's website.
It's almost though as if traces of 4.4.2 are left on the phone
1)The default Huawei boot animation doesn't show, it just says Android still while it use to be sparkly animation
2)The drop down menu bottons are still showing and I can still swipe up and down to hide it.
3)When you reset the phone the default screen with the 2 people, clock, weather etc isn't there, it's just a blank home screen
4)When you swipe down, no buttons to turn on wifi/mobile data etc is there
in About phone it says:
Emotion UI 1.6
4.2.2
Kernel is 3.0.8-00780
So I'm not sure what to do at this point?
Any advice?
Please and thanks!!

Got it working!!
Flashed TWRP, Wiped Dalvik, System and Cache.
Rebooted into Bootloader
Flashed stock recovery
Rebooted into stock recovery with UP/VOL+-
Flashed B125
All back to normal.

[Q] sm-T210 brick - screen doesnt detect

Ok
i updated the firmware with odin last version to this OFW T210XXANC2_T210OXXANC2_T210XXANC2_HOME.tar.md5
All worked fine and the tablet kept the data, etc.
Now i installed the cwm and the 'android-armeabi-universal-root-signed.zip' from it.
For some reasson the tablet now is bricked for unknown reassons and its screen doesnt respond to finger touchs.
The tablet buttons and sound and booting works, but because the screen doesnt detect touchings, i cant do anything.
I have tried to install other cwm versions etc, and to reinstall the firware, and also that pre-rooted firmware on this forums, reset factory from cwm, etc. No success unfortunatelly.

HELP! LG G2 Screen Won't Come on But Touchscreen responds

I've had a long journey with this phone. Only got it a week ago. I downgraded the phone to the LS980 ZVC firmware using LG Flash tools, rooted with ioroot 25 and flashed TWRP with Autorec. Then installed the Cloudy G2 2.2 Rom. USed it for a while, but then wanted a taste of lollipop. So I downloaded the latest CM12 nightly. Upgraded TWRP to 2.8.4.0 using Blasgator's bumped zip, did full wipe, flashed the CM12 Rom, flashed the ZV8 Radio and then flashed gapps. Booted into CM12 fine and used it for a while. Then, the phone randomly shut off, and wouldn't power back on and I panicked. Power button gave no feedback or sound. I decided to try download mode and plugged the phone into my PC, it was detected and flashed back to to stock firmware, still nothing on screen. The phone boots and I can here sounds, I can also hear touch tones when I touch the screen, but I have nothing on my display. Please help. It would be tragic to lose my phone after less than a week

Did you have anything on the screen when it was in download mode? If not, sounds like the display is toasted. Where did you get it from, did it come with a warranty?

Thanks for your reply, I got it off eBay used. But to anyone else who gets this problem, plug in your phone, it will get irregularly hot while charging, but leave it overnight. You'll wake up with a battery at %100 screen I reflashed CM12, and all is well.

[Q] LG G3 D855 Security Error

Hey there. I've been using Candy5 for a bit, but kept a nandroid backup of stock. Today I restored stock (was working for a day) but when I tried to restore back my Candy5 nandrood backup from recovery it won't boot, and shows up a LG logo with 'Security error' under it. What may be the problem? I had to go to work and left my phone at home. Will look at it in a few hours,just wondering if you guys saw something similar? Any workarounds to that? Or how to fix it?

Jast flash aosp kernel Furnace od 777jon.

How do I that ? Can't access recovery because it won't boot. From what I've read so far D855 can't go into fastboot.

Have you tried with button combination volume down and power to boot in to recovery? If not then go into download mode with volume up and plug usb cable and reflash to stock rom with Flash Tool.

Didn't even know the combination exists, was used to it from former Sony phones, but it isn't working here.
Yup, reflashing stock now, thanks.
The problem prob was I installed recovery through AutoRec app. That seems to be for 5.0 only.
Which is the best recovery/kernel for 5.1.1?

Furnance and 777jon kernel both are good and work well on 5.1

reboot to recovery with hard keys (hold power+volume down, when see the LG logo, release and hold again keys, then you see the factory reset option, double yes)
flash your current rom again, (no need to GApps again, just rom) wipe cache+dalvik, reboot system.
AutoRec is the problem for me to see this error, and my solve
sorry for bad english

D855 - Blackscreen / Freeze / Bootloop after flashing Nougat / Only Stock-Roms work?

Hey there,
I recently tried to upgrade to Nougat 7.1 by flashing Lineage 14.1 (latest Nightly) or Resurrection Remix 5.8.0 / 5.9.2 via TWRP 3.1.0-2. But somehow I can't get the system to work.
At first I went from Fulmics 6.9 to Lineage. TWRP -> Factory Reset -> Flash ROM -> Flash GAPPS 7.1 Pico -> [1st attempt Reset Cache + Dalvik] / [2nd attempt: Factory Reset] -> Reboot. Same procedure for RR 5.8.
After flashing the boot animation appears for a while and then, finally, the screen turns black, then reboot. When the screen is black I can still push the power button and hear the wakeon sound. But the screen is still empty. At some point I managed to get to the first step of system configuration (language selection) just by waiting one or two minutes. But on the next step the screen tuns black again and eventually freezes. Sometimes I can even see the status bar and change the volume bars for example, but the installation process somehow cannot initialize properly. Most of the time the system just turns black, freezes and then reboots sooner or later. I tried different builds of RR (5.8.0 of 2016 and 2017 as well as the newer 5.8.2) and Lineage (13.0 / 14.1) but the issue is always the same.
On my first attemps - coming from Fumlics 6.9 - I even had problems with the modem. But after switching between 30B and 21C flashing ROMs (7.1 in particular) went mostly fine.
In the meantime I have even performed a full reset via LGUP / LG Flash Tool 2014 to D85521C_00_1204.kdz, Android 5.0 LP with Baseband 13.2-00002 (modem 21c). After rooting with Kingroot, applying TWRP with AutoRec and upgrading to the latest version (3.1.0-2) I tried the whole thing again.
Flashing Nougat RR / Lineage, Gapps, then Factory Reset and Reboot. The issue is still the same... blackscreen, freeze, reboot. Also flashing MR_Bump.zip after the Nougat / Gapps makes no difference. When applying the .zip via TWRP, the system suddenly shuts down and reboots, then the same Nougat bootloop as mentioned before.
Interestingly it isn't even possible to flash back to Fulmics 6.6 after trying a 7.1 Nougat version. When flashing the system just shuts down, then reboots. The ROM won't install. Other MM ROMs have problems after trying to flash Nougat, as well. For most of them I get the same bootloop / freeze phenomenon.
So the only chance is to completely reset back to LP 5.0 via LGUP / Flash Tool 2014 again...
I am not really sure what is going wrong with the system. But generally speaking LP and upgrading to MM and its variants appears to work fine.
Only trying to flash Nougat leads to perpetual bootloops with any ROMs.
Is there any chance to make Nougat run on my D855?
Anything else I could try to fix the issues mentioned above?
Would be grateful for any help!
Edit:
After installing another 6.0 Marshmallow yesterday I oncemore tried flashing two other Nougat ROMs. The first one was AICP, the second crDroid. When flashing in TWRP I noticed that there was a basband incompatibility again. The ROMs required the 21c, which was already installed (by the lastest MM 6.0) but still marked as unsupported. After that I tried flashing Step-hans 21c in the first place and finally got the two ROMs to install. However, after the unconditional flashing procedure I always got two lines of an "Unknown Command [log]" error...
AICP just gave me the black screen after the boot animation again, but suprisingly crDoid booted without any issue. At least I could make it run normally for one or two minutes. Entering the menus, pushing buttons, opening apps just worked fine for that short period. And then the screen finally faded to black again. I could still use the power button and see the display powering on and off. But the screen itself was still black. Maybe my device has problems with running Nougats system UI...?

Any idea? :'(

Did you wipe the system partition before flashing?

Thanks for the response.
Yes, I did

One month has passed and the issue unfortunately still persists.
I have tried to flash an older Lineage version (v13.0 with MM) the other day and realized that even that one had troubles with my phone.
The UI was very slow and finally crashed to a black screen. In some cases only (pices of) the top bar were visible after the UI crashed. So basically the same as with the newer Nougat builds. I also noticed that at some point the screen toggled between full brightness and a yellow mode with lower brightness (reading mode?).
Could those issues be realted to the kernel?
In some rare cases I can get the newer builds to run for maybe 3 or 4 minutes until the UI finally crashes / the screen turns black. I can then push the power button and hear the wake up effect, but the screen remains black. The nougat builds were also running very slow in those few minutes whilst maxing out the temperature of the cpu.
Any further ideas?
Would be glad for any advice!
Edit:
Stock LP and MM with 21C and 30B still work perfectly, and even very smooth.
But as soon as I try to upgrade to another MM such as Mokee or Lineage 13 or the newer Nougat builds, the screen turns black when setting up the device.
It looks like only Stock-based ROMs (Nimax MM or Fulmics MM) appear to work at the moment!
