Okay, the One X did not satisfy me on the root level as I was thinking it would and recent phone swapping around with the family, I have passed on the One X to my mom. Already did a factory reset (was rooted, but not running a rom) Had TWRP recovery.

So, tonight, I did a factory reset, brought everything back to pretty much stock, an OTA was waiting, it downloaded, I went ahead to install it, the phone rebooted and brought up TWRP. I was hoping it would break the custom recovery like it seems to happen on my N7, but it did not. I could not find it to install, so...

what do I need to do here? Can I install the OTA from TWRP, if so, where is the file hiding? If not, how do I install the stock recovery? I believe the firmware is still 1.85! Yeah, I know... Kind of rare.

The bootloader has been unlocked.

 

Fastboot? I take it I need adb and likely windows to run it, correct?

I think I know where to find a stock recovery.

Edit: I think I just found a Mac version. May give it a go my next day off.
