k550i no network coverage after unlock with furious
 

that's not the first time but i've repaired this type of problem when i've the original gdfs but those time the phone come like this after unlock with fg so daniel there is a real solution?:D:D

That problem has nothing to do with unlocking as no GDFS is touched. Try better check if isnt barred and if so chnage imei.

the imei is not barred , i've do it also with another new phone not locked for adding arabic language and it's the same problem , so daniel can u give us one smart solution to repair gdfs in db2020 without using the complicated way of setool

To repair taht you need activation dongle and tahts why service is complicated and expensive. I don thave that dongle so cant help.
