restore to 4.2.1 - bb 6.15
« on: December 29, 2011, 02:48:54 AM »
Dear all,

tks for excellent cfw, but now i 'd like to restore to fw 4.2.1

so before i installed "iPhone1,2_whited00r5_U" i had fw 4.2.1 with bb 6.15 and unlocked ultrasn0w, and i install with iTunes the cfw iPhone1,2_whited00r5_U and its great, my iPhone 3G works faster. but know i'd like to restore back like before to 4.2.1 (bb 6.15).

i try several tutorials, but with no success - iTunes every time give me error 1604 or something like that

it is possible to turn back to 4.2.1 (bb6.15) from your cfw whited00r5?

tks for all
Hartmann

tks for the answer, but i'm in mac osx,

so i try the following with success:

1. i use Redsn0w to puto iPhone in DFU mode
( i've backup custom_firmware_421_w/bb6.15 when i maked for the 1st time)
2. So in iTunes Alt+click (mac osx) i select the custom firmware above
3. 10m to install with no errors w/ custom logo
4. i like to iOS4 wallpapers, battery percentage and multitasking open again Redsn0w, i select on it Official firmware 4.2.1 from apple and run it
5. with selection only iOS4 wallpapers, battery percentage and multitasking
6. and it worked like a charm

tks again
great year
