Cannot unlock E5838

[TonyWong]

Dear Sir
I buy 15 credit from this web site. I remove the sim card and connect my E5838 wifi router to my PC. The DC unlocker sofware can detect my router as follows:
Found modem : E5838
Model : Huawei E5830/E583x
IMEI : 354105030012669
Firmware : 716.11.17.05.107
Dashboard version : UTPS11.302.16.04.157_MAC11.303.07.06.157
Serial NR. : Y34CAC1981300369
SIM Lock status : unlocked

However the unlock button is disabled. How can I do to unlock it?

Regards,
Tony Wong

Is there original sim inserted when you detect? Try to detect with not original sim inserted. Is lock status same with not original sim inserted?
