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:

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

Networks Austria T-Mobile n78 China China Mobile n41, n78 China China Telecom n78 China China Unicom n78 Finland DNA n78 Finland Elisa n78 Finland Telia n78 Telia Norway Germany Telekom n1, n78 Germany Vodafone n78 Italy TIM n78 Italy Vodafone n78 Netherlands T-Mobile n28, n78 Norway Telia n78 Telia Finland Spain Vodafone n78 UK 3 n78 UK EE n78 UK Vodafone n78 USA Sprint USA T-Mobile This list is taken from OnePlus 8 (IN2013) 10.5.7.IN21BA firmware version. Policies are same betwewen US, EU, India and CN versions but hardware supported 5G bands are different.

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.

Before edit any files, make backup all files what you will modify.

Now you can modify band limitations and CA combos to XML file.

Adding 5G support

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>

After modify file, please make sure XML syntax is valid and upload file back to phone. Reboot your phone and then your phone load latest configuration. On OnePlus 8 and 8 Pro you may have to enable NR calling to *#*#4636#*#* -> Phone Information -> Set preferred network type -> NR/LTE/TDSCDMA/GSM/WCDMA.

You can see your OnePlus is connected to 5G on CellMapper App.

5G Status: Restricted = Your mobile plan doesn’t allow connect to 5G NR. Please contact to your network.

5G Status: Not Restricted = You don’t have enough good connection to 5G NR. Go to outside and move to closer of 5G tower. You can try also put phone to Airplane mode on / off.
