Hi
currently i have iphone 3GS with Ios 6.1.3 BB 06.15.00
i want to erase this baseband and make restore again because my iphone is factory unlock already and i don't need that BB but when i trying to do that on Redsn0w 09.15.b3 i select the IPSW 3gs 6.1.3 and select "downgrade from ipad baseband"
then enter to DFU mode and then its write "Waiting for reboot" and stuck on that not continue process.
have i don't something wrong with the process? or i need to do other method to get rid of this 06.15.00 BB?

I assume that the phone is factory unlocked. safe method is to flash version 4.1 and then do downgrade baseband with redsnow . But somethimes phone stuck like this 'cos of computer ,drivers ,cable etc.
In the first place try to do it on other PC .

You need to select ios 6.0 not 6.1.3

thank you for your help,SOLUTION: eventualy I restarted my computer
entered redsnow 9.15.b3, selected ipsw 6.1.2, then in redsnow selected Jailbreak,
marked only the "downgrade ipad baseband" option, it loaded few minutes then I got iphone 3gs factory unlocked on ios 6 with other BB (that I don't remember the numbers right now) but still write no service and didn't recognized Sim cards, I thought about RESTORE on iTunes, but then I got on ITunes ERROR 3194, tried the TINY UMBRELLA for this solution, but got ERROR 11, I entered redsnow again and made a fully restore with the redsnow, then everything has fixed. :-]

If your iPhone 3GS factory unlock then 1. connect your iPhone 3GS in recovery mode with your pc open itunes then restore 6.1.3 2. Open latest redsn0w select ipsw 6.0 > back> jailbreak> juck check mark on downgrade from iPad basband . 100% try this
