SIM card wont connect to a network on a new ROM

[aleksjug]

Installed a new ROM today and after that my sim wouldn't connect to network so i couldn't make calls or text, so kinda useless right? I tried diffrent ROMs and nothing worked now I can't even access my recovery, what can i do guys?

first check if yr IMEI is still there

if yr imei is still ok, still cannot coonect to network, then change the IMEI number

How do you "just" change the IMEI number...?

[stevenma61]

there r few ways to change the IMEI number

1- mobile uncle tool
eng mode MTK
connectivity
cds info
radio info
phone 1
then hit "AT+" then enter any character, then delete the character, u will see
AT+EGMR=1,7,""
then input any 15 digit number in betwen the ""- example "123456789012345", try to stay close to yr ori imei number
then
phone 2, same ecept 1,10,""

or

2- MTk droid tool
wait till the bottom left box become green
then write the imei number, then unplug the phone(must) n reboot
