1. Download Fix Recovery Here The Firmware Umbrella - TinyUmbrella
2. Download zlib1.dll from Here zlib1.dll free download - DLL-files.com
3. If u are fixing iphone 3gs open fixrecovery43 then put ur iphone 3gs in DFU Mode and let the command window do everything for u "NOTE" *If u are fixing iphone 3g open fixrecovery421 then put ur iphone in DFU Mode*
4.If u did everything correctly ur iphone 3g/gs should be in recovery mode "Its normal"
5.Then use iREB RC4 From here iH8sn0w.com | Jailbreak your iPod touches and iPhones
6. Restore to 4.1 then u gonna get error "1015" download Tinyumbrella to kick out of recovery mode The Firmware Umbrella - TinyUmbrella
7. Finally just jailbreak ur iphone and unlock if u want!

**THIS IS ONLY FOR iPHONE 3GS/G**
**ONCE AGAIN I DON'T HOLD RESPONSIBLE FOR ANYTHING, U SHOULD BE OK IF U FOLLOW MY STEPS I HAVE DONE ALREADY MORE THEN 80 PCS WITH THIS PROBLEM**
