    during installation of PMP_U550_GT-S7562.zip it says signature verification failed

    • Boot into CWM
      Go to install zip from SD card and there you will find an option to toggle signature verification.
      Just turn it off.

      • Mad Darson

        HI Rajan, please help me out in turning off the signature, i tried several times to install the ROM Im continuously getting the error.

  • DJGP

    hi, i install the PMP custom rom on my S7562L and now i have no signal, somebody can help me?

    • There might be an issue with ROM because the ROM’s listed above are for Galaxy S Duos S7562 and not for S7562L

  • princce

    i done format/system under cwm and now is it possible to install pmp rom by odin which i used to root my phone

    • Yes @disqus_a1C8b8I5PQ:disqus . You can follow the steps mentioned if you have successfully rooted.

  • Ben

    Hi Rajan, is there any specify baseband requirement for PMP Rom??

    • No @disqus_g5XvVfZEow:disqus. You just have to check whether the Custom ROM is for your smartphone and the base ROM is same.

      • Ben

        Rajan, the custom ROM is for my phone. But what is base ROM??

        • For all the ROM’s mentioned above, the base ROM should be the stock ROM from Samsung, which your device came with.

      • Mohammed Zeeshan

        can i install any other rom which reflects the specification of my phone but not same brand.

        • Hello @disqus_k78e5G9Eoo:disqus
          No you cannot install any other ROM even though it has the same specifications. The ROM will not be compatible and will brick the device, rendering it unusable. Always ensure that the ROM you need to install is for your specific model.

  • Pink Maya

    tnk for the help you give me

  • Thashreef

    hey bro
    what about google apps…?

    is it necessary to download and install after installing pmp ultra rom….??

    • Yes brother. You have to flash Google Apps package after flashing the ROM because the developer hadn’t included Google Apps with the ROM.

      Do let us know your experience and the ROM features or bugs.

  • shadab

    it says unfortunately settings has been stopped in pmp ultra v 8.five

    • Was there any issue while flashing the ROM? Flash the ROM again to rule out any flashing related issues. If the error still persists, it can be the problem with that ROM.

    • Mohammed Raees

      hey you must install both updates….then it will be perfect…

    Hi Rajan, I installed the KyleOPEN successfully but the problem is that it isn’t showing the gallery and video player. is there any solution for this?

    • Hi Ali,
      You can install these from the play store. MX Player is a good option for audio/video playback.

  • sayyam

    • Hi Sayyam,
      Have you unmounted your sdcard using GL2SD or similar app? If yes, you have to mount it first.

  • Robin Dsouza

    Thanks fro the ROM. I flashed HyperX™ ROM and its been very smoothly running and i even liked the interface..
    Only thing is that, i didnt lke the icons used in notifiation toggle, like it could have been more creative i feel.
    Hoping for a good future 🙂
