    only bugs i found in this F4K update is in the tethering and we cant use a wonderful feature i.e. WI-FI direct.

  2. Reply arjun April 5, 2013 at 9:53 am

    It is a wonderful and stable update.
    After this i also updated to XYLON mod 4.2.2 which eats us too much of battery(had to recharge my phone battery 5 times a day)
    Finally rolled back to the F4K custom mod 4.0.4 which is a very good one.
    Waiting for a stable Jelly bean update for I9000.
    If any stable one please provide a link for the same.

    Thanking in advance.

    Hello Pradeep,

    I own a GT-i9001 XXKG1(Samsung Galaxy S Plus) which is on FW2.3.3 and kernel
    I understood the only difference with the i9000 would be a higher CPU speed on the S plus.

    Is this custom ROM also suitable for this device?

    gr Gerard

    Does this update work for GT-I9000M?
    I am right now on the official Gingerbread 2.3.3.
    Can you please recommend the most stable update to ICS that works with this specific model, and the steps to get there?
