XS++ is not able to flash the K850i yet :( I know which firmware I need but it's on davinciteam :(. It's this firmware: K850i Red CID52 1202-5694 R1CA037 K850 1201-9794 CUSTOMIZED UK/ BLUE. I will need to flash, finalize and perhaps change CDA. If someone can spare 1 or 2 credits, that's all I need :(
