hariskt · 10-13-2011, 10:22

Hi guys i have downgraded iphone 3gs 4.3.5 to 4.2.1 and 4.3.3...without shsh blob...let me explain exactly what i did....

1. Get the Latest Redsnow

2. Get the latest Tinyumbrella

3. Put your iphone in DFU Mode.

4. Then open "Redsnow" and put your phone in "Pwned DFU" mode

5. After that open "Tinyumbrella" and choose the button "Start TSS Server"

6. Now restore your phone with any version of custom Firmware (4.2.1 and 4.3.3 Tested and working)

7. But you can see the result blackscreen and itunes will say to Restore again

8. Now just open "Redsnow" again and try jailbreaking... then choose "Install Cydia" wait until finishing the jailbreak.

9 After that you can see you phone will work perfectly without any problem...

Regards
Haris

itunes version must not be equal to 10.5 ! If wrong pl correct me.

I noticed one more thing - you have not changed the base band of your phone. Phone is still on valid modem.

HERE most of the unlockers are not on genuine factory modem firmwares.
ALL have updated or SAY all were forced to change the modem bb to ipad bb v6.15 to achieve ultrasn0w unlock.
