Have had this issue before but have solved it with retoring backups etc.
have firmware version RUT9XX_R_00.06.07.4
Want to upgrade to RUTXX_R_00.7.00
The result is that the mobile configuration fails. If I restore the configuration backup it will not work. the only way of solving is to downgrade and restore the same backup.
Has this statement any thing to do with my problem? Mine is a **G1*** device.
Note: FW version RUT9_R_00.07.00 and above will not be supported on legacy-design (RUT950 *G1***) devices.
The mobile connection type is NCM and the operator is Telia
