first nexus phone
so if youre rooted on a stock rom, if you accept an ota, do you lose root?
Yes, though if you're on a custom firmware you won't get OTA's pushed to you, at least not on the N1. Root doesn't really matter on Nexus phones though, as the bootloader is fully unlocked so you can just flash a rooted ROM whenever you want through the bootloader. Tbh I never even use anything that needs root access except Rom manager, which you won't need if you're accepting a stock ROM.
Edit: To clarify, root is totally unnecessary on Nexus phones to flash custom firmware, you can flash it with an unrooted phone through the bootloader.
just make sure the second you get home with it just fastboot oem unlock it so you dont lose anything too important
What does that do?

the command unlocks your bootloader, but when it does that it wipes your device, so its best to do it when the device is fresh so you dont lose anything

So basically, put the phone in debug mode and hook it up to the PC and just type in a command in adb?

Nice. I've never owned a nexus before so forgive my ignorance. 2 questions: how do you fastboot and what is the adb command? I have a samsung fascinate, so I'm very familiar with odin and download mode, and with adb as well. But not fastboot.
Sent from my SCH-I905 using Tapatalk
Install the android sdk and a jdk, plug your phone in, in fastboot mode (a mode like download mode but for fastboot) go to the platform tools dir, using your os command line or prompt type fastboot commandhere in this case oem unlock.
Fastboot is a program like adb that comes with the sdk

When you are booted into bootloader but a "fastboot devices" does not list your device, it's almost always caused by having installed either no driver at all or the wrong one. Use the naked driver, follow the link in my signature to find it.

What you see is the stock recovery. Android will flash it back automatically even after you've flashed a custom recovery. To prevent this, you must either rename/delete /etc/install-recovery.sh OR rename/delete /system/recovery-from-boot.p.
LTE radios are in the factory images. Read this: http://forum.xda-developers.com/showthread.php?t=1626895

Navigate to the folder /etc with a file manager. Remount with RW rights (root explorer has a convenient button for this) and rename the file install-recovery.sh to install-recovery.sh.bak.
Then reflash a custom recovery. This time it will stick.

you didnt even bother to read the link i posted....
that has all your answers. go read it.
Using the Nexus tool kit all you need to do is make sure you have a good copy of the stock Verizon os downloaded from the Google site (JRO3C0) or whatever it is. Then connect your phone with it powered down. Select the option saying the phone will not start (bricked) and select unroot with factory image and follow the prompts. This will unroot your phone and flash the stock Verizon os. After that I would re-lock the boot loader, disconnect your phone and pull the battery with it still on. After you power it back up you can enable debugging and unlock and root again. Sorry if I called the steps the wrong name as I do not have my computer with me and cannot look directly at the wugfresh tool. Hope this helps out.

If possible help me make it stay on cm13 or marshmallow

I'm not 100 percent sure, but I believe you need installed TWRP. Tethered wont do. I could be wrong tho.

Is your bootloader unlocked?
I have the same problem, I followed a guide I found here on xda to unlock the bootloader of the ze550ml mm beta, problem is that, after using that guide and supposedly unlocking the bootloader, using the twrp i found in that guide i tried to flash the latest cm13 build for my device but it always goes to fastboot, also the only recovery that works is the twrp I found in that guide. Please help me fix this.

Do you have the advantage drivers and fastboot installed on your pc? Did you go into developer mode in your phone and turn on USB debugging? Lastly, did you authorize the pc to debug your phone?

Hi guys
Noob here, but with a somewhat decent understanding of flashing and I'm kinda riddled by my current situation.
The current state of my phone is:
Locked bootloader.
Access to TWRP (2.8). Access to MTP and install function within TWRP.
OEM unlocking NOT allowed (since I can't boot into the OS).
So the logical thing to do (and as req'ed in dozens of threads with the same problem) would be to flash a custom ROM via TWRP's Install function, boot into it, enable OEM unlocking, unlock the bootloader and do whatever I want from there.
Except ... that all the ROMs I flash are stuck in bootloop. They go through the flashing process, TWRP shows success and then ... an endless android (or custom) loop when I reboot. I tried flashing PureNexus, Cataclysm and Chroma.
Any idea on what might be going wrong here (I thought of the vendor.img I have on right now being a wrong one, but I have no idea how to flash the good one without access to the vendor partition) ?
Any help would be appreciated, I saw that I could go through the LG flashtool/TOT unbricking method but I don't have i. a PC (I'm on a Mac) or ii. an original Nexus USB cable so that would put me back a few days.
Cheers

How did you get in this sh!tuation? Did you OEM lock with TWRP installed?
Anyway, the TOT method is most likely the only way to get it going again. I wouldn't waste my time doing anything else. Ask a friend/family member to borrow a computer with windows on it.

I'm thankful for any help, sorry if I was dissmisive. I'm not aware of flashing through ADB, just sideloading.
I can flash via fastboot, but can't right now because of my locked bootloader.
Presently I can sideload via ADB in recovery (which amounts to the same as flashing from recovery if I understand correctly ?) but any other flashing/thinkering via fastboot/ADB is verboten because my bootloader is locked.
If you're thinking of something else I'd be glad if you could detail your thinkings and the steps I'd need to make
@chafouin you just reminded me that Google is posting full OTAs. At least for the Android N developer previews. So theoretically you could factory reset from recovery and sideload an OTA. OTAs don't require an unlocked bootloader.

In my experience *on the 5x* locked bootloader doesn't allow you to flash factory images.
I haven't tested with latest bootloader, but that has been he case with past bootloaders.
Other manufacturers and phone models handle things differently.
You can however now flash stock using the FULL OTA provided on the same factory image site. In that case you would use adb sideload, not fastboot.

Have you tried factory reset from TWRP?
If I were you I wouldn't try to flash to stock unless as last resort. Locked bootloader with TWRP installed is better diagnostic situation that locked bootloader with stock recovery installed. If you try to flash to stock it is too easy to overwrite your TWRP with stock recovery (it happens behind the scenes)
That is ok, if you are out of options, but I would exhaust all other options first.
