MOD PLS Delete This Post: LG P925 2nd Call Fails, Greenish Screen After ICS Update

EDIT: MODS
Made a faux pas, please delete this post, I will re-post under LG Thrill Q&A

My friends LG P925 would make one call then if she made any subsequent calls she would not hear her even though she could hear them. I thought if I updated OS from Gingerbread to ICS it would solve the issue. Well I left it updating OS on my laptop last night via LG software. This morning I found it had completed the update but now phone's screen is greenish. All I see is black and green or a greenish screen. I tried to remove battery, turn it off , restart and such but the nothing helped the greenish display. I didn't have time to test if the calling was issue was fixed.
Now my question is how do I fix this screen,
What causes the phone to make one good call then mess up subsequent calls?
What is the solution for that if not updating the OS
I am also curious if updating OS also updates the phone's radios?
