Hello,
I have a GL-inet GL-XE300C6 with a EP06-E modem running this firmware : EP06ELAR03A08M4G
Seems like I cannot send SMS with the latest firmware version of this 4G router and it is supposedly linked to the fact that the modem firmware is too old.
May I ask :
- What is the latest possible firmware version ?
- Is it possible to have the firmware changelog for each versions between mine and the latest ?
- What is the firmware upgrade procedure ?
- Is there a way to downgrade if it is not working better/worse ?
Thanks !
