Hi! I have a KF300, and I want to unlock, but have the phone version : KF300cHL_V10a...I flash the phone with LG-KF300_KF300cAT-00-V10a-712-01_EN_ES_PT_FW.crb
and after with LG-KF300_KF300cAT-01-V10b-724-002_EN_ES_PT_FW.crb, and always I can get signal with any band. And I still get Unlock failed with this soft version
Please Vygis Team help me, how can I repair this signal problem?
BR
