Can't boot into any other rom after Android N. - Nexus 6P Q&A, Help & Troubleshooting

I like swapping between new ROM's, and I've been on Android N since the first preview. But now I'm interested in trying out Paranoid.
The bootloader is unlocked and I have just reflashed TWRP. But it asked for a password in the start which I got passed where I wiped everything on it. But whenever I try to boot into any rom (not just Paranoid) it's just stuck on the Google logo. Why so?
Will I need to downgrade my bootloader to the version from Marshmallow or am I missing something?

I'll give the default answer to any ROM issues you ever have on a Nexus device. Reflash the FULL stock factory image and see if it fixes it.

Basic Android Mod 101- BACKUP, BACKUP, BACKUP!!! Always do a backup, Nandroid b/ups are best. With Nexus device's you can unroot, and Flash the entire Google stock image. Brand new again.

Yeah that won't work since the vendors are different. There's a thread already about downgrading from N to Marshmallow..
http://forum.xda-developers.com/nexus-6p/help/trying-to-manually-downgrade-android-n-t3391373

It is all about the boot.img image.
if you flashed a rooted rom, flash the modified boot.img that allows root ( you can find it for each version here http://forum.xda-developers.com/nexus-6p/general/stock-modified-boot-img-regular-root-t3306684 )
if you flashed a non rooted stock rom, flash the stock boot.img ( you can extract it from the stock image file
that's it

Just flash the correct vendor image for Marshmallow.

help with update from 4.2 to 4.2.1 stock rooted

Hello. I searched the forums and came up empty.
I have a stock 4.2 ROM I rooted. When the system says its updating and rebooting. It kicks me into recovery screen and does not up date.
Do I have to unroot and re lock the boot loader?
I know I'm probably just missing something stupid.
Thanks for any help.
If you were on a custom rom before then your recovery is probably messed up and not the stock recovery. Otherwise I do not know what it is that can be doing it because every time I would flash back to stock 4.2 I would get prompted to update to 4.2.1 and as well to note I have an unlocked bootloader and from what I have read before being rooted shouldnt make a difference.
Perhaps you could grab the toolkit and flash the stock recovery that is in it to your N7 and see if that helps you out.

Crap. I was hoping I didn't have to reflash. I dont have a custom ROM never have. I just unlocked this and rooted.
I'm going to try the toolkit when I get home revert from stock to stock, see if the update takes then.
Thanks for you help.
Edit. Looks like I have twrp recovery. This is my issue I assume. Is there a zip I can just flash to update
I have removed twrp back to stock recovery. Now when system reboots to install update, it stats the update then gives me a error. No error code just error. I really dont want to wipe my device as I have it setup for my liking.
I'm using wug's toolkit
I think (...and may be wrong...), but if you modified anything in /system (deleted any of the stock apps and/or updated them) it won't update either.

Is it possible to run the Android N DP ROOTED ?

I'm picking up a Nexus 6P this week, would like to try out the latest Android N DP #4, but I always like to have Root on my phone, mainly for ad blocking and custom Kernels. So my phone will be brand new, should I just try out the Developer Preview before I do the whole Root and TWRP thing ? And then after that root it and install custom Recovery ?
I just didn't know if there were custom ROM's based off the Developer Previews ? Or at least Root available while running the N preview ?
You can have root and twrp on N dp4

Thanks, but right now I'm just running stock, haven't unlocked bootloader or anything yet, but I did enroll for the N beta, which I'm on right now.
Question, if I want to unlock bootloader now, and root, etc... Do I have to revert back to Marshmallow first ?

No all can be done on n unlock boot will wipe the phone then fastboot modified boot.Img that will decrypt the phone then twrp then flash SuperSU in twrp that should do it
PLEASE HELP:
Ok need a little help, I am following the excellent video by Rootjunky ( thank you ), and got through the unlocked bootloader part easily, and now installed TWRP Recovery, but upon first time booting into TWRP, it's just sitting at the Blue and Gray teamwin screen, and not doing anything else, it's not actually entering into the Recovery, to see the list of options, etc...
I powered the device down, and started up again in Fastboot mode, then chose Recovery, and does the same again, just sits at the blue gray colored teamwin screen, and does nothing.
What happened ?
UPDATE:
I powered the device down / off. Then started up again, it went and booted up, to the fresh clean Android N DP 4. But I am not rooted at all yet, due not being able to fully enter Recovery and flash the SuperSU zip yet.

Help downgrading from Nougat to Marshmallow and/or getting rid of System apps in N.

I have a problem with Nougat, and that is - i can`t deinstall system apps. I tried it with system app remover, but it fails on every app. Next i tried with a file manager, but that doesn`t work either. The folders + apk`s just won`t go away, even after a restart. Then i tried to deinstall some stuff via TWRP file explorer, but got a blank screen without any apps after loading into system again.
It wasn`t anything critical for the system to work (i know what i`m doing) so i don`t get where the problem is. I then tried to install Marshmallow, but got into a bootloop and had to reinstall Nougat.
So, if someone knows how to get rid of system apps on Nougat, or if you know how to downgrade, please tell me both. Thanks.
are you root? if so, i've had luck modifying system with Root Explorer. (not sure which explorer you were using)

I've had luck removing system apps with FX explorer, but I had to remount system R/W before it would let me. Also I'm rooted.
I'd advise against tying to downgrade from Nougat at this point, it has caused bricks for many people.

If you wish to get rid of system apps, simply flash via recovery, the lastest supersu vip; system[less], whichever your preference. If you haven't already flashed twrp after flashing Nougat, do so first.
Install Titanium Backup, and you're all set; I've done it myself and works as it should.
If you were trying to downgrade to Marshmallow, you'd need to do a backup + full wipe, and install the M bootloader, boot, system, etc, then you could restore a custom ROM backup, if you had one.

At this point i would wait unless he signs up for the beta. Dozen of us have restored our phones
We flashed that it's over custom rom/ wrong steps to upgrade.

With out unlocked bootloader I don't really know. I guess you might be able to run a factory image . The latest from googles developers site .

Thank you all for your answers. I didn`t bother trying another root explorer as i thought they`re all the same, but i will try the ones suggested here. And yes, the phone is of course unlocked and rooted with the latest twrp and supersu installed.

Thanks. I flashed the latest twrp and supersu before upgrading to Nougat, and they both made it through, so it`s all set up.
I think i`ll try to downgrade since i don`t see the big Deal with N as of now + i have a much worse mobile data signal after updating to it. It`s almost constantly on H instead of 4g /LTE.
If someone is interested in downgrading, here`s an exact instruction that i found here on XDA:
"Download the MM stock firmware and extract all of it to a folder. Then open a cmd/terminal in the download folder (shift and right click in windows I believe, just right click and there will be a option in linux).
Then do these steps in order BACK UP YOUR APPS!!"
fastboot flash bootloader bootloader.img
fastboot flash radio radio.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
The names will be a little different, and if you want twrp put it in place of the stock recovery!
PS: Don't flash userdata
If that fails, i`ll install titanium backup to at least get rid of all the google stuff, like music, photos etc.

@Heisenberg Do you know of a safe way to downgrade our 6p from Nougat 7.1.1 on Pure Nexus to Marshmallow?

When I got my phone back after RMA from the BLOD it was on 7.0 and the first thing I did was flash a 6.0.1 factory image. I picked the same build number as the last Pure Nexus build in MM. I don't think flashing factory images through fastboot is a big risk as long as you are paying attention and following a good plan. Any other opinions are welcome.

Dude, does it fixes your lte issues? Because i am facing the same problem with my nexus 6p + android 7.1.1.
I personally have never had lte issues on any build, 6.x.x or 7.x.x on any custom rom or stock.

https://developers.google.com/android/images You need a complete factory image flash, including /data.
I had LTE problems from 7.1.2b to 7.1.1 (while I didn't have them on 7.1.1 before switching to 7.1.2b) and they were solved by factory reset.

Need help !

Hey guys I recently restored a nandroid on my 6p from a 7.1.1 rom but I get stuck on boot logo now when j go to recovery(TWRP) all my files are completely gone? and it says something about encryption ...did I brick my device? And if not what steps do I have to do to get back up and running again? Like download rom gapps and SuperSU all over again on my PC etc..? I know my bootloader is unlocked still and I have to be rooted still since I can go to twrp so any help will be appreciated thanks.

I am not exactly an expert, but I would recommend to flash back the latest image from Google...go back to completely stock and then if you want root and install TWRP again. Good news is your bootloader is still unlocked, so I don't think you are bricked. Good luck!

Try re flashing the Vendor.img sounds like the vendor didn't get restored
Sent from my Pixel XL using Tapatalk
i would but everything (files etc.) are gone from my phone...so i would have to download and flash it thru my pc right? if not ill probably just flash a rom gapps the vendor of course and super su and see if it boots up to the rom
Yup just download the Factory Image and extract the vendor image and flash it with fastboot.
Or flash another ROM /Gapps/ Vendor

Not clear. The files you had before restore are missing or you miss files from your backup? Twrp backup does not backup your /data/media.
White google logo hanging is a due to bad vendor files.

Stock Recovery is not enough, you will need everything stock boot/system/Recovery, everything should be unmodified.
If you can't update, better is to flash complete stock ROM by fastboot.
Bro research before doing anything to your device! What will u do if the device never boots up next time u flash supersu??? Ever gave a thought to that?
You will have to revert everything to stock. Stock boot.img, stock recovery, remove root and reinstall any system app if you uninstalled any. Revert any boot logo or animation you changed!
After doing all this, you should take the update!
