iOS 9.
2.1 iPhone 4S - FULL
CFW CREATION TUTORIAL EXPLAINED
As I promised in an earlier video, If enough people ask for it, I will make a FULL explained step by step tutorial for CFW creation with proper patches and
Setup.app PATCHED NOT REMOVED.
As far as my research goes on my locked iPhone 4S, the device behaves different than any other. I don't know if
A5 processor has a particular
BUG or this is device-related, but if yous imply delete Setup.app from main
ROOT FS, like you do on iPhone 5, 5C or 4, your iPhone 4S will get to be in an
Apple Logo Bootloop, therefore, even if you manage to push the CFW without an exploit (unlikely but NOT impossible), you will fail at booting.
The solution: We have to use patched Setup.app file that will crash at
BOOT Time sending you to Springboard.
The tutorial itself is kinda the same as on iPhone 5 but with slight and important differences that have to be taken in count when making the CFW.
How about the bloody exploit? Is it required?
Basically, it is.
Apple killed some important bugs that allowed us to restore without any exploit back in summer, but a lot of people on the Forums told me they had success on restoring CFW without any exploit and all of them detailed kinda same scenario:
They used the device in NORMAL
MODE, with
LOW BATTERY and LOW BATTERY MODE ON and they did multiple attempts. They did detailed the lack of any
Service or
Cellular connection tho, but this is fixable in time. We must focus on bypass research for the moment, not on carrier fixes for 4S.
So: Basically you should create the CFW and attempt to "attack" the
NAND of the phone with it while I wait for some good person on these forums or YouTube to give me a
DUMP of iBOOT (taken from a
Jailbroken iPhone 4S no matter which version).
If you can help me with such file, that would be great!
Contact me at office@fce365.info, the file is important as it enables a hugely faster research in
IDA.
