After the phone boots up, press #

Does not work, it says "code error".

BTW, I have this information inside the phone.
Type RH-35 Model 1108b
FCC ID : QTKRH-36X
CNC ID 17-3981
IMEI : 01083600/086717/1
Code : 0527906010626AC
Will this additional information help ?

 

Try another sim, if it is still locked take it to a shop to be unlocked directly with hardware.
