Hello everyone,

Recently one of my friend bought a tubey. And im supposed to assist him in application installations e.g. garmin, games, etc etc.

However, I encountered a problem during the process i.e. expired certificate error. I tried doing a hard reset on the phone- *#7370# with default lock code 12345 & back tracking the date but it still does not work.

I am a tubey user myself too but have not encountered this problem for my phone.

Anyone here encountered a similar problem? Appreciate if some one could advice me.

Cheers! =)

Hello there,

His firmware is still in V11, not V20. So not applicable to do hard reset in that way.
