What happens when you go for a simulated battery pull (hold the power button down for 15 seconds so it turns off)?

Is that what it does, just goes straight back to hboot?

 

Try another recovery? TWRP is much stabler by all accounts (I've not used CWM for an age): TeamWin Projects - TWRP 2.6 - HTC One X (International / Tegra 3 / EndeavorU) | TeamWin

That's an older hboot as well, were you on ICS or JellyBean before you unlocked? (I'm guessing ICS/4.0.x)

 

That's an old, old version of TWRP, the latest version is 2.6.0.0

However, if you've tried to install a JB ROM when you're still on an ICS hboot (0.43.0000), you won't boot which is why I think you're in your current predicament.

There will be stuff still on your SD Card, but because of the way JB ROMs handle memory, a recovery designed for ICS probably won't be able to read things. Try a JB recovery (openrecovery-twrp-2.6.0.0-endeavoru.img) from the link I provided, let me know if you can see stuff on your SD Card once it's installed and then we can take things from there.

 

Ok, head to the main page in TWRP, select mounts and storage, connect your phone to your PC. Once done, select Mount USB Storage, does the phone appear as a disk on your PC?

 

You'll need an ICS ROM, so your options are kinda limited.

Are you carrier branded btw? If you could update to JB, you'd have a lot more choices.

I'll have a look, see if there are still any ICS ROMs kicking about and post them here.

 

See in the first pic you posted, your hboot version is an older version (0.43.0000) and incompatible with JellyBean ROMs.

Were you carrier branded btw? Can you remember what your software number was before you rooted? If yes, you might be able to do a firmware upgrade.

 

I'd need to know the exact software number.

Boot to your bootloader, select fastboot, connect the phone to your PC, navigate to the fastboot folder, open a command prompt and type

Paste the results please.

 

I took out the IMEI and serial for security, thanks.

The good news is that your software number, 1.26.401.2, means you were totally unbranded meaning we can run an RUU (ROM Upgrade Utility) which will wipe the phone clean and install the OS from scratch.

Once done, your hboot will upgrade and once you unlock the bootloader again, you'll be in a position to install JB ROM's. You'll need to relock the bootloader before you can run the RUU though.

It sounds a lot, but it is an easy process and once done. you'll be able to install Viper X.

Sound like a plan?

Either of the top 2 files in the HTC_Europe section.

They should be about 600MB or over in size.

 

Before you run the RUU, you'll need to relock your bootloader, I can't remember off the top of my head, but I think there are instructions on the htcdev ste.

Once it's relocked, reboot to the bootloader, then head to fastboot. Once done, connect the phone to your PC, run the exe file and it'll do everything else for you.

Are you ok with that for tonight? It'll put your phone back into a working state and I can finish up with the ROM install procedure tomorrow? Is that ok? I'm up mega early for work tomorrow.

 

Yep, if the RUU doesn't error, then yes your phone will be back to normal.

The good thing with your software number is that you should be able to run any RUU with 401 in it without issue.
