Disclaimer: The commands below may change without further notice.

Unlock/Openline:
ubus call version set_atcmd_info '{"atcmd":"AT+CLCK=PN,0,12345678,16"}'
Change 12345678 to the unlock code provided by me.

Change imei:
DO THIS AT YOUR OWN RISK!
On stock firmware, bricking the module is very likely!!!

ubus call version set_atcmd_info '{"atcmd":"AT*PROD=2"}'
ubus call version set_atcmd_info '{"atcmd":"AT*MRD_IMEI=D"}'
ubus call version set_atcmd_info '{"atcmd":"AT*MRD_IMEI=W,0101,01NOV2012,123456789123456"}'
ubus call version set_atcmd_info '{"atcmd":"AT*PROD=0"}'

Change 123456789123456 to your preferred IMEI.
DO NOT DELETE IMEI, IF YOU DO,THE MODULE WILL BE BRICKED!
HIGH PROBABILITY OF MODEM BRICK IF YOU CHANGE IMEI.
I DO NOT RECOMMEND THIS AT THIS TIME.

Disclaimer: Educational purposes only.
No bandlocking interface, this is stock firmware factory unlocking.
