APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

    I tried the previous version of ICS near about in Last month but at that time I am getting only 5 hrs backup. So if I move on ICS XXLPH Android 4.0.3 this version then what will be the battery backup time. Can any one noticed the battery backup for Samsung Galaxy SII.

    Please reply..

  • Marco Guerra

    When I installed this version I lost my menu on Power Button (only reboot and power off remains). It is missing Airplane Mode, or Data activaction/deactivation…

    Did I something wrong? May you help me?

      what’s your current firmware version?

  • dr salil

    meant I opened mobile odin -open file-select i9100_code-fash firmware-reboot,again open mobile-open file-select Moden_i9100..-flash file -reboot,then same for GT-i91000-multi csc and finally CF-root(before the whole procedurI backed up all my files at CWM recovery and restored all my data after applying firmware-tick only data,untick kernel, system and cache)and here you go without any yellow triangle and almost no force close-there were too many force close and yellow triangle when I did it via PC odin.the whole procedure took less than 15 min….

    When should i expect an official ics 4.0.3 update for galaxy s2 in India?

  • Josh

    Every time I try this the process fails. Says something about cannot connect to… something.
    What’s the problem?

  • Dithiil

    Just updated and i’m now experiencing network problems is there a solution for this problem?

  • Matus

    its same, if app is on SD card, or internal memory

  • Matus

    Hi. Have you any idea, why I can not install any app(game) from my SD card? After click instal its written Aplication was not installed.. any idea?

  • Cezar

    I understand that you are a very busy guy, but If you read my first posting, I say that I’m on XXLPH.

    I’ve rooted the phone, but Apps won’t move to SD card. By the way Viber works now with a new version by the vendor.
    I hope you understood my question.

    • Pradeep Neela

      i hope your issue is now resolved!

  • Roman

    The usb dongle with a 330ohm resistor dont work. Please help!

  • Dex

    U dont need jig. Just instalit this http://forum.xda-developers.com/showthread.php?t=1494114

  • Roman

    I have made the usb dongle. But it does not work. I have connected 4 and 5 contacts by 330 ohm resistor. Please, prompt to me, whether there are other variants of connection.

    • Neela Pradeep

      we are unable to get your issue

  • Andrew Tsai

    To remove the yellow triangle, you need to buy a special usb dongle which resets the custom firmware counter, and sets the firmware setting from custom to original, just by plugging it in. The usb dongle is just a micro usb adapter with a 330ohm resistor.

  • Cezar

    Hi Sir,
    Could you tell me why apps cannot be moved to SD cards on rooted phones?
    Before following your steps to root Galaxy SII XXLPH firmware, apps could be moved to SD card.

    Any idea or suggestion?
    Cheers.

    • http://twitter.com/pradeepneela Pradeep Neela

      yes you an move the apps! which apps you are trying to move? you can move apps after rooting!

      • Cezar

        Not on this version. None can be moved. Even viber will not work, rooted or not.
