Hello. If your phone stuck on logo you need connect phone to USB cable, press and hold Vol - button and Power ON button. When phone start reboot you need unhold all button and press Vol + button and wait download mode screen. After this you can repeat unlock/repair operation. LG server can’t charge credits twice for same phone.

Also :

1. You need connect phone direct to mother board. Dont use any hub or box for connections.
2. You need download and install latest LG driver ( http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425 )
3. After this put phone in download mode and repeat unlock operation.
