I have a phone with pattern lock. Also lockscreen says: "Call ***phone_number*** if you find this".
Can not acces settings to enable ADB – so used DOWNLOAD mode.
Tried models H631/MS631 – incorrect model ID, LS740/LS751/LS885/LS991/LS996/ – LG_suite says OK, but still see pattern after reboot.
[SPOILER="log PAY ATTENTION TO THE RED TEXT"]
Platform: LG Qualcomm
Selected port: COM70

Please, put the phone into download mode manually (Power phone OFF,
press and hold "Vol+" button and connect the cable (or P990 cable)).

Resetting Screen Lock…OK
Resetting FRP Lock…OK
Resetting screen lock successfully completed!
Performed by 2.2.8 software version.
Maybe the reason is newer software zv7_15 (5.1.1)?
OR I should hard reset/flash phone before reset FRP procedure?
OR maybe root before?
P.S. I wanna help to develop new LG Suite version with LS770 support. Have LS770 VirginMobile, LS770 BoostMobile, MS631 board (should be MetroPCS), Unknown carrier LS770 board…
