New FirmwareBundles to downgrade iPhone5, iPhone4s, iPad2, iPad3

New FirmwareBundles to downgrade iOS 8.4.1 iPhone5, iPhone4s, iPad2, iPad3 ipad4

With this custom bundles you can make your own custom firmware to downgrade, work with ios 9 and 8 32bits versions. also you can download 64bits version not tested,  The iPhone 5S has a 64-bit chip. Odysseus used kloader which is compatible only with 32-bit chips. Only the iPhone 5 and lower/iPad 4 ans lower/iPod Touch 5 and lower . Please try at your own risk .

You will also need jailbreak idevice to save iOS SHSH blobs.

NOT working: iOS5
– kloader does not work properly on iOS5. May be fixed in the future, but
until then, there is no way to kickstart this if your device is on iOS5.
– the baseband for iPhone4,1 is stored differently on iOS5 vs higher iOS
versions. An extra step is needed to prepare baseband.tar

NOT working: El Capitan
– idevicerestore cannot switch from DFU to Recovery. Until it gets fixed,
there is no way to kickstart this if your computer is running El Capitan.

Do NOT attempt this if you don’t know what you are doing. In case of
baseband mismatch, there is no way to get past activation screen and
re-jailbreak the device. To overcome this, a jailbreak.tar and ssh.tar
must be preinstalled to rootfs.
