Yeah
Boot into twrp, go into file manager, mount as r/w and rename that to recovery-from-boot.bak, then flash twrp.

I think I got it to work. I am not sure yet. I just flashed TWRP.
How? What was it?
EDIT: Oh you don't know lol...oh well, at least it works.
It might be because I flashed glitch and the kernel was overwritten.
I updated the software on my DEB Nexus 7 from KOTH49H to KVT49L and now I can't install TWRP.
Are they in progress of making a new recovery img so that it works or should I revert back to KOT49H?
Nah, I did it manually to see if locking and re-unlocking it would allow TWRP to be flashed but, that didn't work.
Don't bother with goo (they disabled downloads and it seems for good reason), see my edits in last post.
