You can still use FAR to upgrade your firmware. and yes, you can upgrade your EROM from brown to red with a EROM patch as it is available.

How can i change the EROM color from brown to red? what software should i use? i'm still a newbie in this customizations thing, i tried FAR once but unfortunately i didn't understand the interface, so i tried XS++ but when tried it it shows that my phone color is brown.

The FW that i like to upgrade to is only available in red so i assume that i need to convert the EROM color to red but i don't know how.

How can i upgrade the EROM using patch?
