I was between roms, was testing out MIUI 8 before going back to Pure Nexus. After wiping I flashed pure nexus vendor img (nbd90x) and then the rom and gapps. I try to boot afterward and I just keep bootlooping from the google logo. I went back and used a 6.0 vendor img (mtc20l) and I'm able to boot into the rom but receive the message to flash the correct vendor img. But I can't since the phone won't boot with the vendor img I'm supposed to be using! I also tried using the stock image for 6.0 and 7.0 from google and neither of them are booting now. Is there something I should do differently or any other steps I can take?
Odd

Factory reset and wipe system in TWRP then try again. Then download the PN 7.0 zip if you still bootloop. I'm guessing you are referring to PN 7.0. If not, fastboot flash the vendor that matches the PN 6.0.1 base.

Anyone else getting bootloops on all custom Roms I unlocked the bootloader and installed twrp latest version though wugs nexus program and I have rooted stock with custom kernel which works fine but is missing a few features I would like to have so I try factory reseting and installing for example chroma or minimal and they both bootloop on fresh install not sure what I'm doing wrong even tried cm13 and same thing but if I flash stock rooted it works fine like normal never had this problem on nexus 5. Any help would be much appreciated.

Not sure that would be an issue, I ran a ROM with an outdated vendor and all that happened was I'd get a popup reminding me that it was out of date

I'm having the same problem as you. No matter what I end up bootlooping at the rom splash screen eventually. Even after the rom appears to be doing well.

Most likely a vendor issue. I had the same. Most roms are fine with the stock Google vendor, except for SinLess rom (which I use) that has its own vendor file. Its a new thing that came with the 6P and 5X I believe.
If you're on stock already and you have the factory image from Google, extract it, you'll find the flashall script with another zip file containing system and other images. If you're fine with flashing over, run the script. If not just extract the second file, you'll get the system, boot, cache.. imgs as well as vendor.img
Code:
fastboot flash vendor vendor.img

Must we flash the vendor.img after every rom?

Nope, once, and you should be good. Unless you somehow managed to erase it in recovery or something. If you see a bootloop again, you know what to do. Its just another partition like system, cache, recovery..
Like I said, only some roms require you to flash their own vendor images. From what I know so far, SinLess and PureNexus.
I'd try a stock rom with the stock vendor first, if I were you, just to get things running. Then flash a custom rom.

Slight correction, aside from screwing over with the actual partitions being the cause, it's mandatory for every major android update from google (e.g. 6.0 --> 6.0.1) if you want to update your rom to the following android version (For just nexus as far as i'm aware).
The images that needs to be flashed when updating are radio, vendor, boot and bootloader. (Unless stated otherwise by the developer of the rom you wanna use)

Hey guys,
Today I tried to go from the Android N developer preview back to Cyanogen Mod 13 (which I had been running before). I tried installing through TWRP 3.0.0.0 but for some reason whenever I install CM I get stuck in a boot loop at the screen that just says Google but multiple times I've been able to flash back to the Android N Preview. I've flashed my phone many times before and I tried a bunch of different stuff (formatting the userdata partition before flashing to decrypt the phone, wiping and not wiping the davlik cache before and after flashing, multiple snapshots of cm13 etc.) but I can't seem to break that bootloop. I ended up going to Android N after I broke something on CM so I used the opportunity to try out Nougat before I flashed back to CM so I didn't have any back ups (I thought I did but i only backed up apps and app data, not a whole solid backup from TWRP or something). Right now I'm entirely stable on Android N but missing XPosed a little so any help would be appreciated.

Are you flashing the corresponding vendor image? If you do not flash the correct vendor image you will boot loop. I have gone from N to Marshmallow and reverse without issue.

No I wasn't, I couldn't very easily find much information on how to flash the vendor image so right now I'm reverting back to Marshmallow via the OTA opt out, that should do the trick right? If not, I know where to find the vendor image but how do I flash it? just fastboot flash vendor.img or what?
Thanks for your help!

There are two ways you can flash a vendor image. Either through TWRP's 'Install' menu or using the 'fastboot flash vendor vendor.img' command.
You can grab hold of the vendor image corresponding to the build number from here: https://www.androidfilehost.com/?w=files&flid=49333
Thanks to BeansTown106 for the vendor uploads.
Is there anything in particular I need to know regarding flashing from a stock rooted Nougat to the latest CM13 nightly? Or just the standard backup, factory reset in TWRP, install CM and open gapps, and reboot?

Just the usual flash routine. You'll need to flash the appropriate vendor too.

Thanks. I actually went ahead and did the usual flash routine but didn't flash the older vendor... Upon booting it just sat at the Google logo (the text, not the boot animation) for 10+ minutes so I quit and reverted to my Nougat backup. Did it stall upon booting because I didn't flash vendor?

Most likely.

Downloaded the latest version from here for 7.0.0 r14

I made a full system recovery using TWRP prior to install. Used TWRP to install the .zip of the update. install was successful according to TWRP. I clicked to install SuperSU and then rebooted. Now I'm stuck in a bootloop. I tried restoring my full backup from TWRP I made prior to installing the .zip but still stuck in a bootloop. So tried again with my original backup image and also no luck. I currently don't have a USB cable for my phone as I lost it. Any ideas on how to get out of bootloop? I've left it in the boot cycle (colored google splash screen) eachtime for at least 30mins. I can still get into TWRP and bootloader. Any help would be much appreciated. Thanks in advance.
Edit:
I ensured I wiped prior to each restoration. I also ensured that on my backup prior to trying to update that I selected all options in TWRP.
What version of TWRP are u using ?
And you wiped system/data/cache b4 flashing PN 7.0 ?
Then flashed PN 7.0 ROM/Gapps/Vendor ?

TWRP version: 2.8.7.2
I wiped system/data and cache
I didn't flash vendor or Gapps. I currently have 0 ways to put them on phone. I'm gonna try to get a cable tomorrow and attempt to put them on but I don't know how I will without being able to get into the android OS. Now I'm trying to figure out what Vendor img I need.
A little more digging and I scrounged up my long lost cable.
Used fastboot to push new vendor.img and gapps.
Booted up like a champ. Thanks man

If you are using Nougat ROMs, you need to upgrade TWRP to 3.0.2-3.

I purchased a used Nexus 6p from ebay. I've unlocked the bootloader and installed TWRP. When I boot into recovery, I get a screen that's titled, "Mount Decrpt Data". It wants me to enter a password. I don't have the password. What are my options?
I want to root the phone and install custom ROMs.
@msmcintosh- The 6P defaults to data encryption on first boot. You need to do a factory reset and before booting to the OS install TWRP and then boot back into TWRP (reboot recovery). If you want to keep your data unencrypted you now have to either flash SuperSU or a custom kernel. Either of these will disable the force encrypt flag. Also make sure you are installing v3.1.1.0.

I managed to screw it up. I'm stuck at the Google screen. I can boot into TWRP. I had tried to install Pure Nexus, GApps, Magisk and Franco kernel, but obviously didn't do it correctly. How can I recover my phone?
Uppdate: I download and installed the Oreo factory image and flashed it. Then TWRP. Now to figure out what went wrong flashing Pure Nexus. I'm coming from a nexus 6.

I keep screwing this up. I have TWRP, factory Oreo, rooted with Magisk. I made a backup in TWRP. I per Pure Nexus instruction, I installed the Vendor image, Pure Nexus ROM, GApps and Magisk. The system won't boot. Gets stuck at the Google screen. Can't boot into TWRP either. I can reflash TWRP, but the backup is no good (gets stuck at Google screen). I end up reflashing the factory image and TWRP. Then it will boot into Android.
I'm not sure what I'm doing wrong. It was easy to do this on my Nexus 6.

Not sure what you are doing wrong with the clean PN install, but you can't downgrade from O to N by flashing an older PN ROM. You may get more specific help in the dedicated PN install thread by nathanchance.
