Can anyone help

CMR2020

the following error keeps happening as anyone had the same experience?

this keeps happening over and over. i did think it was internal error with the unit but have swapped it for a new unit and it does it exactly the same 

Hi,

You wrote you use a CMR2020. A CMR2020 only supports G2 mobile network. Is 2G still available in your country?

i have just checked coverage on the vodafone website and 2g is still available in my area.

it does connect to the network for a few minutes each time then comes up with the error, screen shot attached

Hi,

for CMR there is a new firmware (V2.2.11) available to support LOGO! 8.4 (6ED1052-xyy08-0BA2).
