Trying to downgrade baseband, but iPhone is getting stuck on Apple screen after running downgrade.

It does not work. I have tried about 10 times but to no avail. I have a 3gs with ios=4.2.1 and BB=6.15. Any tips would be appreciated

Baseband is empty and wifi has been disabled after this update in my 3gs 5.0.1.

that’s what happens when you do NOT read the IMPORTANT part.. You just flashed your new bootrom 3GS and bricked it.

I have three iphones that this happened to 1 3gs and 2 3g’s. I have played with em off and on for months now and finally got the right mix on one of them and now have it back to jailbroken and unlocked. it was a 3g and I do not know what exactly I did different this time but I got all the IMEI stuff back on it now and the wif fi works and the thai sim I tried in it ,as I am in Thailand works. I may try this downgrade thing now and see if I can make that happen too. Who knows may get lucky.

Only the NEW_BOOTROM 3GS is not reversible, atleast with any available solutions. Others can be fixed.
