Hello everyone,

I have iphone 3gs (old boot rom). The firmware is 05.16.08.
Can anyone please tell me that how can I downgrade it to 05.13.04

Please help because I don't receive any signals on my cellphone anymore after mistakenly updating my firmware

Flash the iPad Baseband, then downgrade it. Result is 05.16.08 -> 06.15.00 -> 05.13.04
