[happywookie28]

The Firmware version im running is NTG9X50C_12.06.21.00  i bought it from AT&T but now Im using a Cricket SIM ,, im experiencing issues with my devices, it Reboots on its own from time to time and sometimes it just disconects the wifi and i have to reboot it to get it to work.. is there another update that i have not gotten?

is there any way possible to update to the latest firmware without having At&T service??.. im currently on Cricket network

AT&T is using its own server for FW upgrade. So you have to use AT&T network in order to get the upgrade.

Thanks
