I found that newest firmware for modems are:
EM060KGLAAR01A11M2G_A0.300.A0.300
EM060KGLAAR01A12M2G_A0.300.A0.300
I asked on quectel forum for these firmware but im not getting any answer.
Maybe you - as client who is buying their modems can ask Quectel for firmware and share there with the users, please?
