I have a problem, which I don't know how to solve.
Of course I had a root. I have installed busy box and trickster MOD in order to disable 3D scaling to boost some games like NFSMW (Actually, it worked!).
With no rebooting I tried to delete PlusOne.apk and PlusOne.odex from system/app to speed my phone (this app running in the background all the time usses the memory). I used Total Commander mounting R/W, but didn't unmount it.
Next I rebooted my phone.
First, it was stuck on Upgrading Android - optimizing apps (i see it for two seconds on every normal boot, so I thought it may take longer this time but after 10 minutes nothing happened). I tried to do a hard reset, and afer doing it, now, the phone is stuck on lg boot animation.
Could you help me solving the problem? Please tell me what was the problem that I can avoid it in future.
