![Root ANY HTC One X! [Windows/Mac/Linux][ATT/International][One-Click Method]](http://i2.ytimg.com/vi/S4pg9PNLfEk/0.jpg)
I has just successfully rooted the One X with the new ATT OneXroot. Tried flashing the newest rom IceColdJelly and now I’ve bricked the phone with the qhsusb_dload device issue. Fantastic! Frantically searching for a possible fix. Any ideas?
Usually when that happens, it means that your partition has been corrupted. Use TWRP to mount the sdcard(by the way this only works for Windows PC’s) to USB. When Windows recognizes the drive, it will tell you that you have to format your drive(A.K.A the sdcard you mounted via TWRP) before Windows can utilize it, select okay/next and use all the default options. Once it’s done formatting, flash your ROM’s “boot.img” using fastboot, and then in your newly formatted, and mounted sdcard, upload your ROM again. Once everything has transferred over, do a reboot in fastboot. Reboot into recovery and reflash your ROM. BTW this trick does not work with ClockworkMod, just TWRP rocovery
Do I need to install some other drivers to get Windows to recognize this device now? The phone is just black and I can’t get to fastboot. I did install twrp before all of this happened, but it’s probably hosed with the rest.
I bet you forgot to flash your ROM’s “boot.img” first, before you installed the ROM, didn’t you? You cant really brick your phone, unless you immerse it in water or something like that. Tell me what you see when you start it up and where the screen gets stuck, and I’ll try to walk you through it unbricking it
I did flash the boot.img, but am wondering if possibly that was corrupted somehow? I don’t know. After flashed the rom and then the boot.img, the phone booted but sat at the opening HTC screen for a long, long time. After about 15 or 20 minutes, I tried to get to fastboot again and that’s when Windows said something about the driver and I saw that it was the qhsusb_dload driver that was missing. The phone is completely black, but the computer does respond when I plug it in. What can I do? I’ve got Linux, Mac and Windows computers to work on if needed.
Thanks for helping.
Okay, so do this, download the HTC driver, the fact that you even got a response from Windows is good. Once you install the HTC driver, you should be good to format the sdcard. Let me ask you this, are you extracting the boot.img from the zipped ROM itself? because it’s not recommended that you use another ROM’s boot.img.
Download the drivers here: “http://androiddrivers.net/htc-android-drivers/download-htc-one-x-64-bit-windows-drivers/
Make sure that your flashing the boot.img first with fastboot before you flash the ROM with recovery
The problem is that the device does not show up as an HTC device now. Its a qhsusb_dload device and the drivers for that really don’t help much. And, yes, I extracted the boot image from the rom and then installed it manually. This seems to be a known issue especially with that rom (icecoldjelly) on the 2.20 one x. If you can figure out this one, you will be a hero! There’s a whole thread on this on the xda site.
I got the same issue…. if you know of any way to fix this please help and let me know

Rooted HTC One X per your video/instructions a few weeks ago. Boyfriend went to install ROM, and something went wrong…now the phone won’t turn on, if it does, it goes off within a few seconds. I tried your above video, and was able to “Relock” the boot loader, then chose “reboot” – within about 3-4 seconds, the phone went black like usual, so the next steps could not be performed. Please help!
does this work if you unlocked the bootloader with the supercid? my cid is 11111111
I successfully rooted my device through this website and i downloaded TWRP. When i tried to flash CyanogenMod 10, the phone got stuck on the CyanogenMod loading page. I couldnt recover my stock rom through recovery and now when I try to plug my device to the computer, it doesnt show up on computer when im in recovery mode. It only shows up at the CyanogenMod’s boot screen and i cant get into the sd card.
I hope I havent bricked my device.. Can anyone please help me?
Thanks so much for your time

You didn’t flash the boot.img of the ROM you were flashing first. Extract the boot.img from the downloaded ROM and flash that through adb with your phone in fast boot
Sorry im a noob so could you explain a little deeper. Also my computer doesnt pick up the device when connected…. how do i solve that? Sorry for the trouble….
Thank You again
Max please help..in one video you said you would how to explain this with a custom rom. I tried this with a custom rom and my phone is now stuck in boot loader mode and it says tampered relocked security warning. I cant go into twrp recovery and I cant boot into the rom again because when I flash the boot in recovery it fails. Please help, I really screwed myself. Thanks if you can help. Thanks and Please respond fast.
sorry when i said flash in recovery i mean flash in fastboot mode

gI had the Sam problem…just go to the unlocking vid…then if u still have it unlock code file…follow the steps…then mount and format the phone and flash a Rom of your choice and go to downloader to flash theboot..img
Hii…I need ur help. Few days ago I rooted my htc one x att and installed cm10.1 as per ur guidance. Soon after I unrooted it as per above instructions and installed stock 2.20 RUU successfully. Today I tried to install stock 3.18 RUU downloaded from htc usa website, but after finishing up the procedure my one x is not booting up…no lights no blink no response. Plz help me to get it back.
does the RUU 2.20 file still work with the current version of my android HTC XL 4.1.1 jelly bean? if not where can i get the latest one?
after successfully following this procedure i tried to update my phone to official JB by following steps written under heading of “Manual system update instructions:” and now my phone is bricked. please help!
i forgot to mention the website: http://www.htc.com/us/support/news.aspx?p_id=464&p_name=htc-one-x-att
My AT&T One X is S-OFF and I have a newer HBOOT than the one shown in the video. Does this matter?
will any root work with AT&t one x andriod version 4.1.1
Awesome guide! Nothing worked from xda but this one did! I am finally “unrooted” back to stock and bootloader ‘relocked’. Thank you!
Thanks for the video. Got stuck in a boot loop on my fourth ROM install on my HTC One X+.( Its my first Android phone and I have the urge to try everything.) I used a different root method. After watching your video I felt confident this could be fixed.Followed your instructions and now I am back to trying different ROMs. By the way I did forget to flash boot img. Won’t make that mistake again. Thanks Again
Hi, I really need your help. I tried to follow the steps and unroot & restore my att one x. When I use the ruu to recover the system, it shows the progress bar but stuck at the “waiting for bootloader” step. My phone, after the reboot, shows a HTC logo in the middle of the screen and froze. After a while, the program said the connection was failed even though it was actually not.
Fact may help: 1. the firmware is 2.20 which is the same as the ruu.
2. I only have laptop so I tried on three laptop and the results are same.
Appreciate your help very much!!
Hi im try to lock my HTC one X through fast boot my every time in CMD im getting waiting for device error.
