    All the guys having Boot loop issue. I followed following 2 steps to get it working.

    1. Root the phone using http://androidadvices.com/root-samsung-galaxy-gt-i9000-ics-403-rc1-firmware/#axzz1hegvA4Ng

    (Not sure if this step is required, you may try skipping this as I didn’t see any change after applying this pack)

    2. Do not wipe data/cache before applying Wifi fix patch.

    3. Wipe only cache after the patch. DO NOT WIPE DATA/FACTORY RESET.

    4. Reboot system.

    5. Say thanks if it works for you so that I know its working!!! 😉

    Enjoy ICS. 🙂

    seems like i am not the only 1 with the fix issue for this. I had installed firmware 4.0.3 rc1 over miui as stated which works fine also rooting works fine, but wifi does not even switch on. if i install this so called fix i keep getting the constant reboot and cannot get into recovery mode even when i take out and reinsert the battery. can u help or even sugest a fix that works. other people on this have said the same as me.

        I was on MIUI and all was well, I installed the ICS 4.0.3 and worked properly only no wifi, and then I wanted to fix over WiFi fix, of course, before that! I did root the ICS 4.0.3
        But when I installed wifi-fix system was not able to boot but got stuck on samsung logo, the bigger problem is that I could not get into the recovery mode but at least I was able to dovnload mode so I returned to 2.3.6VZ
        All I have repeated, MIUI installed – installed 4.0.3 ICS – ICS 4.0.3 root – and then WIFI-FIX but the problem is still there.
