hello XDA. I appologize if i am breaking rules but i dont know what else to do with my phone.
I recently bought an AT&T X. it had the 2.20 at&t firmware installed. i managed to root it and supercid it and unlock bootloader. however, ever since then, i cannot update thru RUU. i was updating to 2.14 hboot to get facepalm s-off.

writing zip ...
<bootloader> adopting the signature contained in this image...
<bootloader> zip header checking...
<bootloader> zip info parsing...
FAILED <remote: 99 unknown fail>

i tried downloading the OTA and made sure its AT&T software as i do not have s-off yet. I have flashed stock recovery (i had twrp installed after i rooted and supercid) and navigate to OTA files but i get this.

mount SDCARD failed 1 times
mount SDCARD failed 2 times
mount SDCARD failed 3 times
mount SDCARD failed 4 times
mount SDCARD failed 5 times

i chose apply from phone storage and i get:

invalid operation
rebooting...

also i ran JET and successfully downgraded hboot to 1.09 cuz i read it not all parts of s-on were implemented, so i thought i could obtain s-off that way.

i have searched all over xda and google. i do as much research as i can first.
