SE K790 change band 900?

Hi to all

Can I change band to 900 MHz using the script used to do it on w200 ???

I've made many change band in w200a for example and it works like a charm.

But does it work on this SE K790 db2020:

PHONE STATE: "RETAIL"
FLASH CID: 0051
Speed:921600
LDR:071130 1150 NPACXC1250330_DB2020_PRODUCTIONIDLOADER_P3M
FLASH ID: 2019
OTP LOCKED:1 CID:49 PAF:1 IMEI:35xxxxx CERT:RED
ACTIVE CID:51 COLOR:RED


Thanks in advance
