    Thank you very much for the great rom. Installed it using twrp. Runs smooth and stable. By the way I tried to update firmware using fastboot but it fails with this message: “missing boot.img file”. Can anyone help me please?

    Thanks for the rom. I find problems switching between the 2 sims data connection. When on sim 1 I cannot switch back to sim2 (must reboot). this problem was not on previous release (4.2 rom 2). I cross the border (switzerland) at least twice a day..
    Any suggestion?

  • giangifax

    Hi, some problems found… I use the italian language.
    1. There isn’t Hotspot Wi-Fi by default;
    2. Sometimes 4G connection is lost (?);
    3. When i set the fly mode, i cannot return to normal model until reboot;
    4. Camera is very very pink! it is much worse.

    However… thank you very much for your work! I wait the next update 😉

    • Guest

      Huh, I don’t think HTC One dualsim supports 4G cellular.

      • giangifax

        or 3G, all sim phone connection

  • robytrav

    I have just bought an HTC ONE M7 802w …it’s still a good device with a good price/performance ratio…PLS don’t close the project…lollipop is arriving for it too…:-) many thanks!!

  • robytrav

    I have just done a donation..thanks again for your nice work and PLS don’t let us alone ….i think there are a lot of 802w users around and this is the best ROM for it!!!! tks !


    Dear Llabtoofer, I REALLY do know what it means: EOL, but…..I need to give it a shot as there is no chef like you for the M7 Dual SIM – you did pleasantly surprise us all with V3, would there be any chance of surprising us again by issueing a V4 at some point (4.4.4, or 5.xx)?

  • Денис

    Lollipop? Where lollipop on m7c?

  • Ali

    Can we expect 5.0.2 ROM (or higher) for HTC One 802w dual sim and if yes, then when approximately? Or may be there will be updates for Maximus HD 3.0.0 which I use from the realization date and have no problems with it at all! Thank you so much for very stable and firm ROMs indeed.
    Thank you in advance

  • WaDeMaN

  • Codrin Popa

  • Wizky

    Dear Llabtoofer, as you can see there is quite a number of enthousiastic users of your ROM on the 802W Phone. Could we tempt you in any way to consider cooking an update on the 3.0 ROM?
