iPhone 3GS black screen

[p3bguin911]

hi im on 6.155 bb and 4.1.2. i have my blobs for 4.1 and ive been trying to downgrade. Well when i restore it with custom firmware i first run tss server then enter pwned mode with ireb then i restore with 41 custom firmware. everything finishes fine when it finishes it just goes to recovery mode and i cant get it out. I try to jailbreak with resn0w and it boots up and does everything but when it finishes it goes back to the black screen. Ive tried custom firmwares with sn0wbreeze and pwnagetool and downloaded various others from online but still nothing. Can someone please help me here.

Are you using a custom FW with a 6.15 BB?

[p3bguin911]

no the only thing i add in it is cydia

Ok, you need to make the custom FW with a 6.15 BB because you updated to an ipad baseband. You'll never be able to go back to an iphone bb and will always have to use custom FW.

Had the same problem. If you use TinyUmbrella, and after everything installs, it will put you in recovery, just click "kick out of recovery" on TinyUmbrella.

Wait so when I'm making the custom firmware I click the box to add iPad baseband to it? (sorry for the late reply)

I can't kick it out of recovery because it doesnt show up on tinyumbrella only on iTunes when I put it in pwned state with ireb
