well this may or may not be for noobs.
u have flashed ur phone with a new firmware or just succesfully cross flashed a new firmware. But some times u get a customization error just like i got. I flashed my w610 from r6 to r8 and i got this problem. i tried it again and again but it did not go.
so flash the phone fully with the required firmware and fs pack u need and download cust pack form the download area of TOPSONY. so when u get that error just plugin the phone to xs++ or farmanager or whatever u want go to tpa-preset-custom and put all the files in the folder of custom. DO NOT CREATE any folder. and disconnect it and reboot it u will be free from the ghost of configuration error.
download cust pack that belongs to ur region only or it will not work and the error will be seen again
so this may or may not be for noobs:):):)
