No IMEI, No Bluetooth and No WiFi on iPhone 3G or 3GS is due to Baseband Related Issues

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

We have been getting a flood of emails lately from readers or Googlers reporting that their iPhone 3G and 3GS (and some iPhone 4) about No IMEI, No Bluetooth and No WiFi on their device.

This is definitely a hardware issue – usually a combination of a defective or corrupted baseband processor chip and Intel/Numonyx/Spansion NOR chip, baseband SRAM chip, UMTS Transceiver IC or broken micro components.

This usually happens after doing a restore, or a forced baseband update to 6.15.00 using redsn0w. In a more recent case, flashing iPad baseband will cause this problem due to a new Toshiba chip used in iPhone 3GS.

To those of you who like to scout for used iPhones on eBay, be sure to check with the seller before making your purchase. Otherwise you will end up with an expensive brick!
