On this instruction we will modify OnePlus 7 Pro 5G, 8 and 8 Pro band combo profiles with Qualcomm software. OnePlus has limited 5G access and 4G+/LTE+ Carrier Aggregation combinations and this instruction help you to unlock. However this instruction doesn’t unlock hardware defined combinations what you can see on below but you can example edit software defined limitations with this instruction and enable 5G on your network.
You can check supported combos here:
- OnePlus 7 Pro 5G. OnePlus 7 Pro 5G have only 5G enabled in EE UK and Elisa FI networks.
- OnePlus 8 (EU)
- OnePlus 8 (US)
- OnePlus 8 (China)
- OnePlus 8 Pro (EU)
- OnePlus 8 Pro (US)
- OnePlus 8 Pro (China)
This instruction is tested with OnePlus 7 Pro 5G (GM1920), 8 and 8 Pro.
List of networks where 5G is enabled by default
Your OnePlus 8 and 8 Pro will have 5G enabled in these networks with specific bands. If your network is not in list, then 5G may not be available on your phone without modification.
|Country||Provider||5G Bands||5G Roaming|
|China||China Mobile||n41, n78|
This instruction only allow enable/disable 4G Carrier Aggregation & 5G EN_DC combinations and band support if hardware support it. If hardware doesn’t support, you can’t enable/disable band. Example OnePlus 8 (China) 5G doesn’t work in USA even it support n41 (T-Mobile/Sprint) band because it doesn’t support 4G anchor band used in USA.
After November 2019 update FactoryMode is removed from OnePlus-phones so this instruction doesn’t work anymore without installing EngineerMode apk manually.
Before continuing, i remind you these changes could end your device warranty. Be careful because this can make your device unusable.

Now you can modify band limitations and CA combos to XML file.
Adding 5G support to own network
OnePlus just limit RAT capability on carrier_policy.xml file so just add to rat_capability section “5G” to enable 5G NSA.
<define_fullrat_config> <actions> <ue_mode> CSFB </ue_mode> <rat_capability base="none"> <include> C H G W L 5G </include> </rat_capability> <rf_bands base="hardware"/> <svc_mode> ALL </svc_mode> <freq_list list="default" /> </actions> </define_fullrat_config>
And add “5G” to every rat_capability sections
<rat_capability base="none" > <include> G W L 5G </include> </rat_capability_if>
For OnePlus 8 and 8 Pro you may have to add nr5g_sa_bands and nr5g_nsa_bands to rf_bands_default section.
<rf_band_list name="rf_bands_default"> <gw_bands base="hardware" /> <lte_bands base="hardware" /> <tds_bands base="hardware" /> <nr5g_sa_bands base="hardware" /> <nr5g_nsa_bands base="hardware" /> </rf_band_list>
