ok i have the 4.5.0.93 os and about 25 mb space without any programs and people have like 30 with many apps .. so i want to reinstall the os using the crack mem application.. would i need to wipe the device .. and if i do a back and restore them later after im done with the reinstalling, will it restore the device to how it was before.. like remove programs that were not there.
thanks in advance
