Root Bricked?

[AltitudeJunkie]

Was trying to get Cyanogenmod going on my Nexus 6.
Got stuck in a TWRP bootloop.
Moment of madness, relocked bootloader (because I'm an idiot).

Now have Nexus 6 that will only boot into a TWRP bootloop no matter what I choose in the bootloader. The LOCKED bootloader. That I cannot unlock with fastboot since there is no OS to "allow OEM unlocking".

Any ideas? Please tell me it's not bricked....

Have you tried Wug's toolkit? I think there's an un-brick option that will take it back to stock.

I had a look, but there's no Linux version. Boo. Thanks for the suggestion, though.

As it happens I did a fastboot erase cache, which allowed TWRP to boot, then did a format, then adb push'ed Cyanogenmod. Worked a charm.

You are lucky you had a custom recovery. If you didn't, you'd likely be stuck with an expensive brick
Locking the bootloader, as you unfortunately found out, is a bad idea (unless done correctly)

Its very hard to brick a nexus. I only know of a couple of ways to actually do so. Anytime you can get to fastboot you are going to be fine. It can be re-unlocked with fastboot OEM unlock. It doesnt need to be booted into the OS for that.

Careful, in my experience that wasn't true. You need to be able to tick "allow OEM unlock" in settings. My cyanogenmod mod install failed sonI had no OS to open the settings with! Fastboot OEM unlock kept failing. Had to fastboot erase all the partitions it would let me to get it to boot into recovery.

Strange, I dont see that option on the stock ROM. Could it be an issue caused by enhanced security on a custom ROM?

 

[AltitudeJunkie]

It's definitely in stock ROM, under development options. If you haven't enabled that yet there are plenty of posts on here explaining how to!

 

[Rxpert83]

Ah, I dont even have developer options enabled. Thanks

Understandable,it's quite nice as-is,out-of-the-box.

I'm sure I'll root/ROM mine eventually,just don't have a lot of compelling reasons screaming it ATM........

 

[Rxpert83]

I'll always root. ROM I can do without now. Quick quick settings pull down is about the only thing I miss. I'm not willing to go xposed just for that.
