G977B CSC or Country Vendor Need to be Changes it's Possible ? - GSM-Forum

Hi all,

Can anyone advise me on an issue I have with (SM-G977B) I have Vodafone UK (VOD) and EE UK (EVR) devices that I want to process to a SIM free firmware.
The OXM flashes that I can see/download flash the handsets to Telstra (Australian Network) the region change via a SIM card does not work on them as other S10 models.

Can not flash combination firmware to the device (OEM unlocked or not - PIT or Bootloader permission) so can not manually select the CSC code I want to use (BTU/XEU ideally)
I do not want to trip Knox filter. Has anyone successfully changed the code/made branded S10 5G handset unbranded?

Thanks

I was trying to figure it out as well. Even contacted Three network, as there is no 3 branded firmware, yet they sell this device. But couldn't find out anything. Afaik there is no generic firmware, which is weird because there is for Note 10+ 5G.

There are OXM (multi-region) firmware files out there for generic/unbranded firmware. Just no way of changing what it defaults as I can see.

I don't remember if I've tried it, but did You flash it with combination ? I guess it doesn't work.

Nope, doesn't work. Have been using Chimera to do a CSC select since it was updated with the option.
