the thing that i need is that when i restore to default after some days to check there were no IMEI . it says invalid IMEI and also the same NVRAMERROR. that i fixed it again by the above method that i explained. then i do firmware upgrade but this time i did not select the format option, i just download.but after finishing firmware upgrade, when i turn on my tab it says INVALID IMEI AND SAME WIFI problem NVRAM ERROR. BUT I WANT THAT is there any method from which if i ever do firmware upgrade or restore default it should be fixed and it will not say INALID IMEI AND NVRAM ERROR. I JUST HATE IT.
