After 4.4.2 update last Thursday, my phone system now has wrong time (about 2.5 hrs ahead) and wrong date (Jan 2013). Both cannot be manually adjusted. This is preventing the majority, if not all, data access on phone. Phone worthless at this point.
I have performed following to fix phone:
1) restart / airplane mode etc.
2) Toggled "automatic time from network" setting
3) factory reset and deleted cache
4) removed SIM card
Managed to install clocksync app which is showing correct time from NTP server but not able to manually change date or time.
What can I do? Still have 10months left on my contract.
