[Q] Phone stuck at HTC Logo - ADB cannot detect phone topic

Hi,

I had rooted my HTC One X+ phone quite some time back, and had used a couple of custom ROM's.

Later I decided to install HTC stock ROM and installed HTC Sense 4 version by using ZIP file, through custom recovery. It was working fine.
I had got a message on the phone that an update is available for Sense 5 version (4.2.2 I think). I opted for the update.
After the update, the phone is stuck on HTC boot logo.

Since the phone was rooted earlier, and had installed some custom ROM's, I have TWRP installed on this device, which I can access. When I power on by pressing power ON button and VOL DOWN button, I am able to boot into the boot loader, which shows the following:

**********

***UNLOCKED***
ENRC2B_U PVT SHIP S-ON RL
HBOOT 1.72.0000

HW Secure boot:enabled
MODEM PATH: OFF

HBOOT

< VOL DOWN > ....
< POWER > ....

FASTBOOT
RECOVERY
FACTORY RESET

IMAGE CRC

When I select RECOVERY, I can boot into TWRP Recovery Manager (TWRP v2.4.1.0 Venom)

I have options: INSTALL, WIPE, BACKUP, RESTORE, MOUNT, SETTINGS, ADVANCED and REBOOT

If I select INSTALL, I can see the file system; /sdcard directory is accessible
Under RESTORE I am not able to see file system or packages
Under MOUNT, I am having option to "Mount USB Storage". But this is not helping anything.

Under ADVANCED, I am seeing other options including TERMINAL COMMAND and ADB SIDELOAD

Now, the phone is not appearing as a device when I connect to PC Windows 8.1 (even when I try the "Mount USB Storage" as above). Also, when I connect the phone and try "adb devices", it fails to list the phone. I have installed HTC drivers including HTC Sync Manager. It starts up but says it is unable to connect to the HTC Phone (or no phone connected).

With this situation, can something be done to bring the phone to usable condition? Please let me know if any additional information is needed.

I would like to install HTC Stock ROM with Sense 5. I have a ZIP file for this on PC.

Please help.
