LGQ_1_70SC - LG E720 and E720b added.

New version - LGQ_1_70SC is uploaded at support sites in LG section.
- added direct unlock,IMEI,BT,security,NVM repairing and flashing for LG E720 and E720b.
These models must be flashed with special "E720_E720b_V10_FOR_UNLOCK" flash for
direct unlock,IMEI,BT and security repairing operations.
- improved P500,P503 and P509 flashing - so please use this version to flash and unlock them.
One more thing about P500,P503,P509 and E720 - if flashing fails is needed to disconnect phone
from cable - remove battery - put it back to phone, enter phone to "Emergency mode" and repeat
flashing operation again.If flashing fails and you try to flash phone again without battery
disconnecting - connecting this can cause dead phone on some firmware versions.
