How to Update Samsung Galaxy S GT I9000 with ICS 4.0.3 RC 4.1 Firmware

Samsung Galaxy LogoFor all those who were waiting for an all new update in the form of ICS Android 4.0 flavored custom ROM which is dubbed as version of 4.1. We really thank the developer Paul Forde who has made a huge contribution in rolling out this One Cosmic ICS Custom ROM. Last time we saw on how you can install the RC 2.1 ICS Android 4.0.3 Firmware, RC 3.0 and RC 3.1 ICS Android 4.0.3 Firmware. It was rolled out few days back itself but it was later pulled up due to issues with Wi Fi and Modem. When compared with other builds, this build of 4.0 comes with several performance fixes.

  6. I Have a Samsung Galaxy s GT i9000. I moved from 2.2 to 2.35 after which my wifi and my bluetooth stopped working. I then managed to upgrade to 4.0.3, thinking it would fix the wifi and bluetooth problem. But still it didn’t help. Im still currently on the ICS 4.0.3. My wifi shows me “turning on” but it never turns on. My bluetooth does the same.. I heard about a “bcm_supp.conf” file that needs to be in the folder data/wifi but i don’t have it. i searched to download it but couldn’t find it. so i downloaded and installed the wpa_supplicant file and placed it there, and that didn’t work either. Please guys. I NEED A BIG BIG BIG HELP from you. I have hitting my head in the walls since 3 months to get my wifi and bluetooth fixed. please help me do something and fix it. If possible anyone can send me a download link of the bcm_supp.conf file would be great. However i still need explanation and methods to get WIFI working on my SGS GT i9000. HELPPPPPPP!!!!!!!!!!!!!!!
