You need to flas the phone back to its original state using the original MAIN, FS and CDA for K550.
I don't think it's a good ideea to put in your K550 a software from W610. The reason for this comes from the fact that K series is different from W series. You should know that K series is optimized for photography and W series is more optimezed for music.
I you really want to customize your K550 use software from other K series phones.
I think you already have SETool2Lite and XS++ and know the drill.
You don't have to be so trendy to have a good working phone.
Be well!
