@andy9- i guess u didnt read my post properly,when my iphone was in dfu mode TU could not detect it so using USBview i managed to get my ECID and using that i checked if i had shsh blobs saved but there were none..
anyways.... I GOT It TO WORK
....
as u may know from the thread my newbootrom 3gs was stuck in apple logo/dfu mode / recovery mode after a "Reset all settings" and it was on 4.0.1
these are the tools i used
-Windows 7 64bit
- iTunes 10.1
- Redsn0w 0.9.6b4
- Tiny Umbrella 4.1.13
- Official 4.1 firmware
-Official 4.0.1 firmware
-using redsnow entered "pwned dfu mode"
-started TSS server in Tiny Umbrella
doing the above steps allowed me to restore to stock 4.0.1 using itunes.the restore was sucessful but my phone was now stuck ONLY in DFU MODE ( no apple logo or Recovery),i got really scared at this point,....
i started seaching the net as to what to do....found something so i tried this
-Opened redsnow again and ticked on cydia alone.
-The phone was going through all the stages of jailbreak but redsnow was not proceeding halfway through "Updating Ramdisk".....so i just disconnected my iphone and it went back to dfu mode
-I opened redsnow again and ticked on boot tethered only and whoopie,the phone is up and running again.
im on stock 4.0.1,just have to jb and unlock
i hope this helps others
Edit:
ok i guess the "Updating Ramdisk" part was necessary because i cant seem to jailbreak using limerain or jailbreak me and everytime i power off the iphone i need to use redsnow to "boot tethered now".....so i tried installing cydia again ,this time the "updating ramdisk" got stuck at 30% so i cancelled it and tried to "boot tethered now" but that also got stuck halfway and iphone was not booting up....
again i tried installing cydia ,this time "updating ramdisk" completed,"updating kernal" started and it got stuck at 90%.....anyways i disconnected again and did "boot tethered" and thankfully it booted ,still no cydia installed though.......
i dunno why the "installing cydia" of redsnow stops in between sometime in the beginning and sometime at the end??....any suggesstions
