I lost the bottom piece which is under the charger block when repairing the g3 for a screen is it an important part or is...

Anyone get ahold of one of these now i am strughling to find any on ebay

Solved: if you have done the repair after disconnecting the battery and you still have a black corner then disconnect the battery once more slightly heat the board with hot air where the ic chips lay and your problem should be gone. Happened to me loads recently and this fixed everytime!
