[kolbyw13]

I have a 3gs with baseband 6.15.00
its basically stuck on the recovery loop
i cant restore to stock firmware because im on ipad baseband so i get error 1015
it seems itunes wont except any firmware besides 3g firmware (i have 3gs!) idk?
when i try to restore a custom firmware it sends me a 16xx error

NEED HELP!

You're sure it's a 3GS? Is the text on the back of the phone dull gray or shiny silver?

Edit: regardless you're getting 1600 errors bc you're not using redsn0w/iReb/pwnagetool (which one doesn't matter they do the same thing) to put your phone into pwned dfu mode before trying to restore to the cFW. also ensure you have SHSHs saved for the fw version you're trying to restore to and that the TSS Server in TinyUmbrella is running before attempting the restore to cFW.
