Hello everybody
i download a few days ago the last firmware for my Nokia Lumia800 from Navifirm (1750.0823.8862.13110) but when i start refurbishing it the phone start rebooting and then it turn off and Nokia care suit shows the message (No certificates found inside esco package. Invalid file!) appears. the phone show that it updated correctly but the firmware still the same.
I refurbish my Lumia800 before once by the firmware(1750.0805.8779.12221) then I install windows 7.8 using seven eighter.
so what's the problem ... and can I fix it??
