AT&T HTC One X Rooted On 2.20 Firmware


Oh, happy day, HTC One X users on AT&T. Root has finally been achieved on the device, and the instructions are actually relatively simple.

Those of you lusting over all the ROM development brewing for the AT&T One X were no doubt cursing the stars after updating to the latest 2.20 firmware. Aside from the usual bugfixes that typically come with an OTA (over-the-air) update, handset manufacturers usually take the opportunity to patch up root exploits, keeping bootloaders locked up tight (as per the instructions from carriers), and kept custom ROMs out of the question. This is exactly what happened on the latest 2.20 update, but it didn’t last long.

Last night, XDA member djrbliss discovered an exploit that, not only allowed him to gain super user permissions on the AT&T One X, but also crack open that prudish bootloader as well. The process involves gaining temporary root, and then using HTC’s own bootloader unlock tool to finally gain permanent root, where you can then flash custom recoveries and/or ROMs. With a Jelly Bean update coming down the pipeline, there’s no telling for how long this root method will work, but tis the cat and mouse game Android modders and the OEM’s play.

I've been obsessed with consumer technology for about as long as I can remember, be it video games, photography, or mobile devices. If you can plug it in, I have to own it. Preparing for the day when Android finally becomes self-aware and I get to welcome our new robot overlords.

  1. Sweetness! Can finally rid the bloat from my gf’s OneX :D

  2. Hopefully this means that there will soon be a root method for the EVO LTE on the latest firmware; been kicking myself for updating

    1. I’ll keep my fingers crossed for ya! Gonna root my gf’s One X now and throw some AOSP Jelly Bean on that beezy :)

      1. What does beezy mean?

        1. I believe beezy means an old old wooden ship

      2. Glad I’m not alone! Since I’ve flashed all I can on my S3, I’m in need of another project and hers has been off limits since it came with 2.20.. but now my fingers shall creep to her soft, white…………..ceramic skin :p

        1. Go on… *breathes heavily* O_O

          1. That awkward moment when phones become a fetish… lol

  3. Featuring Paranoid Android screenshots to illustrate root, nice.

    1. One of the best reasons to root, in my humble opinion :)

    1. Ya that got me too lol, only reason why I clicked on this article… I’m sure the 2.2 is just the HTC firmware revision number, not froyo :P

    2. The firmware version number is 2.20.502.7. The previous version was 1.85.502.3_R2. It’s just an internal numbering scheme.

  4. Hey phandroid…. it’s 2.20 not 2.2, just to help with some possible confusion

  5. Not interested. Can’t wait for the Galaxy Note II. The kids can keep playing with the HTC One X phones.

    1. Thanks for sharing?

  6. Why do you need temp root to use HTC’s unlock tool?

    1. alter the CID to “debrand” the AT&T HTC One X, so you can use HTC Dev.

      1. Ohh so it doesn’t work on stock. I see. Should have followed the source link and read first LOL. That sucks though I though Verizon was the only one c*ck blocking HTC Dev. At least they have a solution now.

  7. Ok. The developer used HTC’s own bootloader unlocker to fully root the phone. I think the OEM’s are doing this on purpose to help us and get back at the carriers.

    Did I just ruin their plan? =.3

    1. No, that’s not how it works.
      djrbliss found an exploit to modify the CID to “SuperCID”, allowing it to be unlocked by the official unlock tool.

      1. I know the developer didn’t just use the official boot loader. I figured there was some background work. LoL!! But nonetheless this is still pretty cool and I’m sure there are a lot of happy people.

  8. looks at stock one-x…. looks at article…. looks at scalpel…. back at one-x…. back at article….
    bout to go H.A.M. on this phone…

  9. SO retarded.
    it’s like you don’t actually BUy the phone when paying several £/$hundred you just lease it and the carriers/manufactures retain ownership.
    For all the great technological advances the mobile arena’s bringing, it also appears to be moving backwards in consumer power and freedom.

    1. Unfortunately it’s within their rights to lock devices down. :(

  10. dizzaamn!!! aosp JB looks beautiful on that One X

  11. but it didn’t last long.

    It lasted 3 months!!!!! That is a long time to crack root.

    1. Why all the drama ? is it an HTC thing ? or because they are not using custom rom’s ? (I mean I never have to wait or have any problems with my galaxy)
