Want a full Sense 4.1 experience with option to add your favorite MODs easily?

Well, check out KingCobra 1X ROM, which is exactly that. The AROMA installer allows you to easily add in cool mods like the HQ Camera MOD (for 20mbps video recording), 4×5 Sense launcher, and plenty more.

Some notable features include V6 supercharger script inclusion, leaked Sense 4.5 camera, ICS browser, and a whole lot more.

I think this is a great ROM for Sense-lovers and also noobs, give it a test drive and let me know what you think!

P.S. Battery life is freakin’ awesome if you enable the Dual Core Mod PLUS on it.

For installation, install ROM normally using Aroma installer then try rebooting once if you end up in a bootloop (what I did) and should boot.

  8. omar enrique says:

    hey max,

    I have an at&t htc one x rooted, unlocked bootloader, and with the recovery mode installed and working…. but i cant install any rom on this phone… i try venom and maximus and both fail in the installation….. can you give me a hand? what im missing here? anyway i love your work man keep it going

  9. xblast says:

    I was just wondering if this rom installer(the installer menu that allows you to choose the tweaks you want installed) flashes/changes the kernal version, baseband version, build number, or browser version? I believe I saw something about a kernal change on the first screen…

    For installation, install ROM normally using Aroma installer then try rebooting once if you end up in a bootloop (what I did) and should boot.

    How to install Aroma install and what do you mean? I am stuck in boot loop .

    • Alex J says:

      Aroma automatically launches when you choose the “KingCobra 1x ROM” to install from your SD card from recovery mode. Aroma is where you were able to choose all those mods to install. I myself got stuck in a bootloop and had to get a new phone so I can’t help you there 🙁 Sorry.

  11. branden carrick says:

    WELL, now im stuck in boot-loop.. followed all the directions to the T…. how the hell can i get out of this, it wont boot to recovery?

    • Branden Carrick says:

      Nevermind… Had a noob freak out moment haha… Thought I had to hold volume “up” to get to bootloader… It was “down” haha…

  12. Branden Carrick says:

    Ok… I’ve reinstalled this rom 3 times… Same result, boot-loop!!! This rom is garbage

  13. Jens says:

    I also get stuck in bootloop . Seems rom loads fine, but i notice it hangs on boot img 98%. When trying to flash the image itself it gives message of:
    Checking model Id
    Hardware is compatible
    Mounting Partitions
    System Partition
    Data Partition
    Installing Stock HTC Kernel
    Extracting drivers
    Flashing boot.img
    file_getprop: failed to stat “/tmp/aroma/custom/prop”. No such file or directory

    Click next
    “the kernel has been installed on your device
    Installer Status: 7
    Touch “Finish”
    and goes into bootloop of “HTC quietly brilliant” Screen
    I had a back up on my internal sd card and that just disappeared after several attempts to install rom. Sd card required format.
    I can still load into fastboot and twrp. I have done this several times just to go back into bootloop. Really lost at this point .
