i just upgraded to t-mobile's 4.1.107 OS

i went to do a hard reset (pull battery) after installing a program like it told me so and when i reconnected battery it was drained (was completely 100% full prior)

can i not do hard resets now with new OS? what happened?

After the battery pull how drained was the battery? You still should be able to do battery pulls.

it was COMPLETELY drained like if i had put a dead battery into the phone.

Wow. I haven't seen that before. Again, I don't think that battery pulls or the upgraded OS should do that. Try charging it up to 100% again and pulling the battery. If it still happens you could try another battery.

Ok its fixed.

The problem was that coincidentally the battery terminals were oxidated/dirty. Little light rubbing of a pencil eraser and everthings back to normal.

That's the first I've heard of it too. Glad to know a fix just in case.
