I think Engineering mode contains the following settings

<Engi>
<LTE>
<mcc/>
<lenOfMnc/>
<mnc/>
<tac/>
<phyCellId/>
<dlEuArfcn/>
<ulEuArfcn/>
<band/>
<dlBandwidth/>
<cellId/>
<rsrp/>
<rsrq/>
<sinr/>
<mainRsrp/>
<diversityRsrp/>
<mainRsrq/>
<diversityRsrq/>
<rssi/>
<cqi/>
<eutran_cellid/>
<ECGI/>
</LTE>
</Engi>

You see we can change the band through Engineer Mode
