Drivers for Windows (if you need it):
Step 1. Copy the custom ROM zip file (do no unzip) to somewhere on your phone. Or you can also download ROM zip file straight to your phone, it should be under Download directory.
Step 2. Make sure USB debugging is checked ON under Settings->Developer options.
Step 3. Open a command prompt (or terminal in Mac/Linux) and type:
cd OneXRootATT
adb reboot bootloader
fastboot erase cache
fastboot boot openrecovery-twrp-2.1.7-evita.img (updated with TWRP 2.2)
fastboot boot openrecovery-twrp-2.2.0-evita.img
Step 4. Before you install a custom ROM, use the Backup feature to backup your ROM!
Step 5. Choose “Wipe” from main menu and choose “Factory Reset”.
Step 6. Choose “Install” from main menu and find the ROM zip file you copied over earlier.
Step 7. Once your ROM finishes installing, reboot and enjoy your new ROM!

![Root ANY HTC One X! [Windows/Mac/Linux][ATT/International][One-Click Method]](http://i2.ytimg.com/vi/S4pg9PNLfEk/0.jpg)
when i did the last part of step 3 in the command prompt where you enter fastboot boot openrecovery-twrp-2.1.7-evita.img, it said failed (remote: not allowed) what does that mean and how do i fix it, thank you
Did you unlock the bootloader?
I got the same thing and it says on my phone bootloader unlocked. It’s a rogers HTC One X
Try fastboot erase cache.
make sure your phone is set for “Charge Only,” I got exact same message then realized I forgot to turn the “Disk Mode” off.
i installed my rom (CM9) but dont have google play store how to do i add it?
flash gapps into your phone
Yes thank you for your I installed Google play but now my HTC one x won’t connect to my hone wifi but will to for example my schools wifi can you help me with this? I appreciate it
Try forgetting network and try connecting again, seems like incorrect password to me.
I’m getting “system already unmounted” when installing a ROM. Then I reboots into normal previous ROM. Help?
Figured it out. HTC Sync was running and had disk already unmounted. Killed it from task manager and installed CleanROM 3.0 for ONE X att.
what did you exactly do? cause I am encountering the same problem.
I already tried forgetting the network then re-adding but it didn’t work. And I have the same system is already mounted error but my main concern is the wifi right now
Hello,
First of all, thanks for all of this. I now have a rooted HTC One X (ATT) with TWRP installed and unlocked bootloader thanks to the information on this site!
But, I am having trouble flashing Custom ROM’s. When I got to flash the AOKP beta ROM for the HTC One X, it gives me an error when flashing, and aborts the flash. So now I just basically have a rooted HTC One X and can’t install Custom ROM’s
You can only install AT&T HTC One X or HTC One XL ROMs please use these ROMs: http://onexroot.com/category/one-xl-roms/
Having a bit of trouble here… After typing in ‘fastboot erase cache’ the command line stays stuck at ‘waiting for device’. I have followed the instructions to the letter. The bootloader starts up on the phone and is functional. Any ideas?
Never mind. Figured it out.
Is there a way to delete some of the backups, I have made 4 already, but don’t need few. Can this be done through evita? Thanks.
Yeah. Just mount your phone as a disk drive, go into your twrp/cwm folder then recovery folder and then pick the folder you want to delete (they are named corresponding to the date of the recovery)
exactly, it’s under ClockworkMod/Backup folder or TWRP/Backup folder.
Hi
I have a problem with the fastboot boot openrecovery-twrp-2.1.7-evita.img – when I have done this the phone have restarted and stack to the booting window – htc quietly brilliant – and it’s not loading.
If I restart again it’s loading normally, but I can’t flash a new ROM.
Do fastboot erase cache then try it.
Hi there,
same here… even tried to do erase cache several times but it still goes into “HTC quietly brilliant”.
Any help?
Will this work with the 1.5 502.3 710RD software of the one xl?
I mean 1.85.502.3 710RD
Yes.
use ur method for unlocking boot loader and rooting in a mac and it was flawless! also flashed a rom for my ATT HOX and great! will post feedback on the ROM! Thanks a lot, great job!
when i typed “fastboot boot openrecovery-twrp-2.1.7-evita.img” the phone is now at the fastboot window and is stuck…can not do anything
Thank you so much for the tutorials. I’ve successfully rooted, unlocked my bootloader, and installed cleanROM 4.0 (4.1 is available now). How do I update the ROM? Do I need to do another clean install or can I simply install an update patch?
Thanks
They usually list in the update description which is okay to do. A factory reset is always the best way to ensure you’ll get a perfectly working ROM.. Again check the xda forum and they usually tell you what to do.
Hi,
I have a problem… When I did the last part of step 3 in the command prompt where you enter fastboot boot openrecovery-twrp-2.2.0-evita.img, it said failed.
What does that mean and how do i fix it, thanks!

I did everything correctly but TWRP won’t flash any roms. It starts for a second and says failed. Any help would be greatly appreciated.
what is the exact error message? It may just be a bad file, try re-downloading the ROM.
You can only flash the roms that are available for the One XL (AT&T’s One X).
So these ROMS
(http://onexroot.com/category/one-xl-roms/)
or the one’s from the XDA forum here
(http://forum.xda-developers.com/forumdisplay.php?f=1541)
Hi. thanks a bunch for all the info. i have a problem though. i still cant enable tethering after flashing the tether hack in recovery, and to be honest tethering is why i put the custom rom. I was using foxfi but it keeps ghosting my data. any thoughts.
try something like this:

but set profile to “Generic ICS” and should work fine.
Hello Max, do i need to unlock the bootloader to install a CUSTOM ROM ? I really do not want to mess up with my warranty on at&t . Thanks!
I tried flashing many different versions of CleanROM for my HTC One X At&t. They always fail with a signature verification error, and I am not sure I want ty try without the signature verification unchecked yet. I Already have a rooted unlocked bootloader and have been running on CM10 nightlies for over a month now. Just want to try cleanrom, but TWRP doesn’t let me flash without the signature verification error. Any ideas on what I should do differently?

i need your help please….
Is your phone the One X or the One XL? The One X is international and One XL is the united states AT&T/Rogers version. If you are flashing One XL ROMs on the international One X then that is probably your problem.
Hello, can you please help me. Okay so, i did everything but when i try to flash a Clockworkmod it goes to the HTC Boot Screen and says something like this HTC device is for development purposes only, in red words. Please help me i don’t know what to do next?

C:\Users\apina\Desktop\onexatt>adb reboot bootloader

I have been successful before flashing custom ROM and am currently running a CM10.1 nightly. I was attempting to use the same methods to flash a more stable CM 10.1 monthly. But now when I attempt to: adb reboot bootloader…I get the error: device offline.. Not sure where to go from here. Any help would be greatly appreciated.
Hi! I’ve rooted my AT&T HTC One X following your instructions of this video http://www.youtube.com/watch?v=jcp4pP5hJIc but mine is s-on, I would like to know how to turn it into s-off in order to install a ROM.
Thanks in advance.
I was able fix this by 1) downloading the latest SDK @ http://developer.android.com/sdk/index.html 2) extracting only the ADB file to 3) copy and paste into my ATTOneXRoot file on my computer and now my ADB commands work again.
