    Your link is for the wrong version of the CM10 mod. It’s not for R800x It’s for the R800i and R800at

      As mentioned on developer page the is for R800(x/-). So, we didn’t put the wrong link.

      • Ed Smith

        Right… but its not zeusc the link takes you to just plain ol’ zeus. At least it did for me.

        • arafat21

          Don’t know what going wrong for you but when we tried to download we see zeusc. Screenshot attached.

  • Dustin Glenn

    this is not for the r800x. this is for a GSM model, not a CDMA. it will let you flash, but when you start your cell, it keeps throwing an error concerning “ has stopped working”.

    • arafat21

      Did you install that boot.img? We actually offer what developer gave us in their official page. According to development page this is for R800x, don’t really know why this isn’t working! Anyway, thanks for the report. We updated the download link. That may fixed the issue.

      • Dustin Glenn

        i am downloading the new link now. i will report back as to whether it functions or not.
        Yes, i know how to flash cell phones. I did install the boot.img.

        • Merrill Scott

          Did it end up working?

          • Dustin Glenn

            no it did not.

          • James Johnson

            Ran through it yesterday myself and ended up with the same result unfortunately. Looking into other custom ROMs now.

      • Dustin Glenn

        I have followed the link. tried the boot.img that came with the rom, tried other boot.img that i know work with my r800x. this rom is not compatible with an r800x. That is now a fact.
