Badly you can't modify any file so you can't hack. Sorryz
Actually you can hack the mobile hardware very easily. Its a neural-net processor called the human brain that's notoriously vulnerable to errors, exploits and gigo reprogramming at the root level. Root admins (parents) find the os extremely malleable. but accumulated errors cause loss of flexibility as the system accumulates extraneous data with age.
Attempts at hard reboots (death) is an unproven method of recovering from cloud storage, but some techs believe partial recovery via reincarnation of the data may be possible via this approach.
