Go to s-off.

Flash firmware for JB ( hboot, etc )
https://www.dropbox.com/s/4fgu7hs7chvt88g/firmware.zip?dl=0 ( rename to 0P4EIMG.zip and copy on sdcard, then run bootloader. This downgrade you hboot etc. )

flash recovery for jelly bean,

flash stock rom for zara UL ( mount system and delete with file manager in recovery file /system/bin/hcheck )
https://www.dropbox.com/s/205a9uuolilh6ot/stock_odex_Zara_ul_JB422_SENSE50_1.10.401.8.zip?dl=0

Child's play, do you mind testing on the CL. I would but my computer is out of commission as of now. Getting together with my Tech instructor to see if we can fix it. Until then, I probably won't be able to help much dev testing. Aside from suggestions and what not.

I've downgraded my zara_ul just by flashing firewater hboot before running the ruu. All while s-off and bootloader unlocked. It'll bootloop once downgraded to jb due to it's hcheck not liking s-off and the unlocked bootloader at the same time but that's besides the point.

That's great. Basically just lock boot loader and you should be fine. We need someone to test on the CL now. Again, I apologize for my inability.

I'm sorry to break in in this conversation, but I have a problem. I followed the guide on page 1. Flashed the firmware.zip, flashed twrp recovery 2.6 and successfully installed the stock.zip from page 1(according to twrp). But when I want to reboot the screen hangs at the htc logo. Anyone know what I did wrong? I checked hboot and it said 2.20.

Thanks for any help.
