  9. Hi Pamela,
    My Phone set is “samsung galaxy sl (GT-i9003).To get better performance like speed up and quick start of any apps and better 3G/WiFi connectivity, should I go back to Froyo or JB. Your expert suggestion please. Hope by doing any changes in original OS, set will not go dead:-)

    Thanks for your creative efforts you did!!!!

    • Well Jellybean is latest but Galaxy SL have not received official upgrade yet. It is better to have system OS (default). But there are handful of apps you can download on Froyo variant. Try out any stable custom ROM and upgrade the device to Jellybean and use the apps.

  10. Hii!! it is very good job

    • Well, it is always been warned that bugs may hit if its not a stock ROM. Being third party developed ROM will have bug issues. If you really getting trouble then I would suggest you to get back to original ROM or try other custom ROMs.

  11. hello can you pls help me how to fix my galaxy sl i9003 bootloop samsung only.

    • While updating if you have bootloop then remove the battery and reinsert again to fix it. If after doing so and stuck in bootloop then you have to update the device again with official stock ROM this time. This is because you might have bricked your device.

        • Hi Vanitha, there might not have sufficient memory in your device or it might be searching for a latest firmware update. Keep at least 500 MB free space in your device for the applications to run and Do check availability of any latest firmware for your device by going through Settings=>About device=>Software update and install the firmware if available. If these don’t work, then let me know.
