Find my post in Lenovo section, about K10A40 FRP,
download flasher from posted link, use appropriate DA_Agent,
replace in CM2MTK folder (search the infinity section for how-to),
after that phone will boot and you can do desired operations
(sim-unlock, FRP remove, factory reset, re-partition, etc.).
For flashing this phone you will need factory stock rom,
don't use readed firmware from other same phone.
