I followed directions to a T when I unlocked my bootloader and installed custom ROMs. I installed the latest factory image before I did anything. No matter what ROM I flash on my Nexus 6P, I've noticed that in landscape mode there is graphical "flickering" on screen-updates (moving anything on the screen) that is isolated to the NavBar. My experience has told me that this is because of firmware, but if I am on the latest and the ROMs are build for the latest how could this happen? Any ideas?
Edit: I have attached a picture of the issue I am having on what seems like every single custom ROM available right now.

XT907 - Running the latest Carbon Nightly, Google Apps, freshly flashed from the old 4.0.4 via CM11. Things were smooth as silk, but I noticed when booting recovery, even before the flash, I have been experiencing moments of garbled screen when going into CWM Recovery. This issue is now persistent before the boot animation plays for a moment, and when turning the screen on, if done in rapid succession, it displays a moment as well. This is nothing more than an aesthetic irritation but I'd like my polished feel back. Does anyone have any handles on this particular issue? It's baffling me. I thought it might have to do with recovery but as far as I can tell that's a silly assumption to make. It's your average bars and colors screen garble and it's usually the same when it occurs. Any ideas or help on this would be greatly appreciated. Has anyone had this issue before or figured any ways to at least mitigate it's appearance?
It's worth mentioning my bootloader is unlocked, as well.
Update - I've identified what's the cause of it. When I install Google App packages, like the PAGApps package, or any of the generic packages it happens regardless of the ROM, provided it's a 4.4 based ROM and apps. Any one have any ideas?
I had that issue with a few ROMs on JBBL. What Gapps are you using? I've had no issues with PA Gapps Mini

After updating my zenfone 5 (intel 2.0GHz) to android Marshmallow screen locks and unlocks randomly when it's laying in landscape or horisontal position(if I handle it with any angle it also does, but less frequently)
I have no idea what to do. I have tried unofficial CM13.1 and Resurection Remix and it's the same(I made clean flash of course). Dirty unicorns doesn't boot at all, so I have no chance to check it.
Maybe I should flash any speciffic firmware to use marshmallow without problems but I have no idea wchich one... (Is there any step-by-step manual of moving to MM and flashing these ROMs? I'm not sure but i think I have used this one)
The second problem but a bit smaller is that I can't connect to the cellular data internet but i'd focus one the first one.
Here's the video:
https://www.youtube.com/watch?v=qEAg6K3z0OE
If I enable any screen lock I just can't use the phone
Before Marshmallow update(on stock ROM, but unlocked) there was everything ok.
It also doesn't locks on TWRP, only on system
thats came from bootloaderunlock you can use cm 13.1 kernel and enable dnxfix for this second dirtyunicorn is booting when you came from cm based roms you must make a fullwipe then dirty is aosp thanks
Thanks
Ok, I flashed CM13.1 boot img. It's the same. I also tried to reflash whole CM from here: http://forum.xda-developers.com/zenfone-5/development/cyanogenmod-13-t3382702 and it doesn't work.
The phone still locks and unlocks its screen :/
I made full wipe of course...
"dnxfix" - do you mean "dnfix" wchich is mentioned in cyanogen's thread? Ok, I'll try it. And slockfix. It looks promising
Have the same problem here. The problem goes away on airplane mode though.
Hello,
I received my Nexus 6P yesterday and got my SIM card activated without any issues at Verizon. I immediately took it home, unlocked the bootloader, installed TWRP, and then flashed CyanogenMod's latest nightly. After booting in, wireless networks weren't detected, and I only had 3G (no 4G LTE as I should). I restored my backup of the stock ROM that I made in TWRP and it hung at the Google logo. I'm not sure why. I then flashed all the latest factory restore images (MTC19X) to get it working again and determined that the issues I had in CyanogenMod might have happened due to the vendor.img I had on my phone at the time not being compatible with that build of CM13.
My questions are:
1) What are the known issues that would likely occur due to vendor.img being a different version than what CM13 was based on? The concept of vendor.img is new to me. I haven't had this, as far as I know, on any of my other phones (granted I'm coming from a locked Samsung Galaxy S5 that I've had for almost 2 years)
2) How can you easily tell which vendor.img CM was based on so you know which one to flash?
3) Is there anything else I should be made aware of before attempting to flash CM13 again?
4) While using CM13, do most people recommend a custom kernel? If so, which one and how stable is it? What are the benefits of switching from the stock kernel, and how simple is it to go back if there's a problem?
Thanks!!
dude...I just got the N6P and ran CM13 within hours. This is what I did...
unlocked the bootloader
downloaded the lastest (MTC19X) image off of https://developers.google.com/android/nexus/images and unpacked it into the C:\Program Files (x86)\Android\android-sdk\platform-tools folder
ran the flash-all.bat
fastbooted TWRP
installed CM13. (didn't wipe internal storage)
installed arm64 open Gapps pico
BAM!!!
right now running stock kernel. it's cool. I'm PrivacyGuard-ing the hell out of all my apps (turned off START AT BOOT and KEEP AWAKE for almost every downloaded app), though, so battery is OK
also using Kernel Adiutor but underclocking values for the CPUs doesn't seem to stick
So it likely worked for you since you had flashed the newest vendor.img first. Apparently there are compatibility issues with certain features that cause them not to work (such as WiFi) if you're using an older one.

1) Depends on ROM /VENDOR, sometimes nothings happens then an error message, sometimes things doesnt work
2) Just download fresh the latest snapshot, release or nightly (they are much more stable then for a few years!) and vendor image (use these ones which are recommended!)
https://wiki.cyanogenmod.org/w/Install_CM_for_angler (there is a link for the vendor)
3) If you stay close on the tutorials, i dont know what should happen (flashing a rom is normally not critical, installing a recovery can be!)
4) Custom kernels can be great, but its not a must-have. Which kernel you should use depends on your wishes: better battery, more power etc.
Hope i could have help you a little bit!

Very much so. I appreciate it!
Has anyone encountered the constant popup of the Select Sim Card message? I'm using project fi and I am still unable to find a solution to this issue.
I just moved from Pure Nexus 7.1 to SuperXE 8.1. I think I forgot to flash vendor image but otherwise did full clean flash. ROM boots but when trying to connect to WiFi there is voice input but no keyboard. Haven't ever seen something like this before... Added vendor image and redid full/clean flash multiple times with same result. Unfortunately, activity on that ROM thread is a bit slow and I'm down without my phone so decided to ask for help here.
Adding $20 bounty for help fixing. Serious withdrawal mode without my phone. I have a backup phone but it is nearly unusable...

Since you are coming from Nougat to Oreo i would suggest you first flash the full oreo factory image before flashing the oreo custom rom. Its not usually a must but solves a lot of minor problems
Hi all,
I'm new to the device so I'm maybe doing something wrong but I don't think so. I got the device with a terribly cracked, I flashed Pixel Experience (Android 10) as it's what I've had on my Nexus 5x, everything was working fine so I proceeded to replace the screen. I replaced it with one from Aliexpress which seems legit.
The phone then wouldn't boot, or seemed not to boot. I saw the splash screen then a black screen. The system did boot as I could see the capacative keys light up and sounds working, I just couldn't see any image on the screen. After a while trying to flash other ROMs and other TWRP versions (at this point TWRP showed up as a black screen too) I found that the following solution solved my problem.
https://forum.xda-developers.com/mi-a1/how-to/solved-mi-a1-bootloop-t3973131
This is fine, I can use the stock ROM and update it to the latest version but cannot use any AOSP based ROMS and still cannot use any other recovery apart from the one used to solve the "bootloop".
Does anyone have any idea how I can solve this? I thought the screen was maybe a weird version that needed some additional drivers but the strange thing is that it works for the stock ROM.
Regards,
Simon

I'm in the same situation. I think these screens are not 100% compatible so it seems a hardware issue.
Maybe using vendor partition but i'm so stucked as you.
My phone can't hotboot any official recovery although i can boot flashed recovery only if i boot slot a not slot b.
Stock roms boot always using slot a but tried Lineage (thats uses slot b) and got always black screen.
I'll keep reading and trying to solve it.
Regards.

Thanks for your interest but I've made no progress and actually given up on it. I'm sure the issue could be resolved by buying a new, more compatible screen but I'm not going to put any more money into the phone.
As far as the software solution goes, I've tried almost every combination of ROM + Kernel i can think of but the only thing that works is the stock ROM.
I'm going to close this thread as I don't think it's much use to anyone.
Regards
Sorry for posting here, but i am in the same and i noticed that flashing canting 4.9 kernel gives display for like 8 seconds after screen turns off. May it be a kernel config issue? if anyone in this forum could answer this i could try and change it. Also flashing stock kernel on custom rom solves the problem but makes other thing fail
Hello, I've got the same issue. Is there any solution ? Or, at least, any clue to work on it ?
EDIT: I finally done it!
with this kernel (OC) : https://forum.xda-developers.com/t/...rkernel-v3-1-nonoc-and-oc-12-11-2020.4186317/
And this rom : https://forum.xda-developers.com/t/rom-11-0-official-crdroid-7-1-tissot-13-11-2020.4195351/
I installed this kernel, cause you was saying it is probably a kernel issue, so I tried to look for most recent kernel.
And then, it worked, so I think you was right.
I can't be sure it will work with all ROM, but I think.
Hello Mi A1 friends.
So yesterday I decided to change my crack LCD screen and to my surprise the phone boots into Xiaomi Logo and then after that its just a black screen. Message and other notifcation sounds still come in which means that the phone mange to boot into home screen, just with nothing to display. At the time of changing screen, I am on stock kernel and Pixel Experience 10.
Gonna flash back to stock pie(9) rom and see how it goes from there.

Sry for reply to an old post, but how did you do it? How did you flash kernel when you can't enter twrp because of screen issues? I have exact the same problem, where stock rom works but everything else cause blank screen. Also can't boot to twrp - probably the same reason.
