Default [Q] Help needed very bad

Hi all. i need help. i have tried everything to unroot and lock my incredible 4g lte. I cant unroot it and tried running a stock rom but it sat at the sending............. part for about an hour. I have relocked it but occasionally when i go into bootloader it says system warning and my bootloader also says tampered which i also want to get rid of. Please help unroot and return my device back to stock everything. I am patient and will listen to it all.
