Yes, this forum does include your device.
Most ROMs will support your device; the only difference between the GT-S6812 models of this device and the others (GT-S6810 variants) is that they are dual SIM-compatible, whereas the others are not. Instructions are usually stated within the different ROM threads for you to be able to enable/disable multi-sim if you need to.
