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

    Please reply..

  9. 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?

  10. 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….

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

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

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

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

  15. 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?

  16. 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.

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

  18. 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.

  19. 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.

  20. I have all steps of the device does not function I was trying in vain to run the Samsung display my sign with an exclamation mark inside a yellow triangle please help.

  21. 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.
