MY friend has an iphone 3g which was jailbroken and unlocked. it was running 4.2.1
He did erase all settings and now the iphone does not get to the home screen. it stays at the pineapple logo.
i want to restore it but unable to find out what BB it was previously.
Have tried to know the BB using USBVIIEW but unable to get that.
It says "CPID :8900 CPRV:30 CPFM:03 SCEP:05 BDID :04 ECID:XXXXXXXX IBFL :00 iBboot - 596.24 ", not sure which BB version this iboot refers to.
What would be the best way to restore it back.
Shall i use the 4.2.1 from apple and use redsnow to jailbreak and ultrasnow to unlock?
or do i need to use a custom ipsw file? or do i need to follow a different procedure?
please let me know.
