    I was trying to update to the latest Jellybam firmware and now has an issue. I was on the codename 3.5.0 rooted update. I wiped the cache / partition and now unable to get into the download mode with the vol down + menu key + power button option. I just get the big X logo on the screen and ODIN is stuck at “setupconnection”. ODIN (v1.78) is detecting device on COM port 7. Could you please help me out.

  9. I have a same wifi problem,no wifi, avoid poor connections

  10. I am not able to use my phone as Wifi hotspot but Wifi itself is working. Also I can’t connect it to my PC as USB mass storage, any solution for that? I have tried USB_mass_storage app to do that but failed. The phone charges when connected but PC can’t detect it.

  11. can this firmware spot indian language….somthing hindi ?

  12. to have wifi, just press the settings button on wifi settings –> advance –> then press avoid poor connections (y)..
    I’m having trouble in texting, sometimes the signal just disappears and reappears when sending a text message..thanks

  13. to have wifi, just press the settings button on wifi settings –> advance –> then press avoid poor connections (y)

  14. Is there any positive feedback of successful installation else only negative issues are posted here. Pradeep, appreciate your feedback.

  15. Dear Pradeep, I am having 2.3.5 presently installed on my galaxy s gt i9003. As per your instuctions I am trying to install 2.3.6 and then root file from android advices but link given is not working . Please help me …..

  16. and the link given for DDKP3 on hotfile is not working…!!!

  17. Hello Neel
    is there any future update to this firmware because i have wifi issue with this rom.


  18. A couple of issues Mr. Pradeep…
    1. I am not unable to mount my external SD card. Please guide me as to how can i do that?
    2. Wifi and tethering does not work. I need these functionalities the most, please suggest a way to make these work.

    Your guidance will be much much appreciated. Thanks in advance.

  19. For all those who are getting the ‘Temporarily avoiding poor connection issue’, it looks like a setting that is defaulted to on bootup. To solve this, go to ‘Settings > WiFi > and then the settings again to ‘Advanced”. You’ll find the ‘Avoid poor connections’ option checked. Uncheck it and you should be good to go.

    But i have other issues with this ROM:-

    1. Stock alarm doesnt work . I can hear it go off but i can’t dismiss or snooze it. Using Alarm extreme App for now.

    2. Battery life isn’t the greatest. But not sure if its a hardware compatibility issue as JB wasnt designed for i9003 anyways.

  20. Sometimes the touch does not work. So, i have to press the power key to lock and then unlock to make the touch work.

  21. Hi Neel,
