Hello Embeded Gurus,
I had an incorrect idea to update firmware on SIM7600E-H module
because there are so many firmware versions online:
So I successfully uploaded LE11B13SIM7600M22 and now there is no way to conect to GSM/LTE any more.
A was learning the problem during some 5 hours. All in all I scanned QR code on SIM7600E-H and everything became clear:
So I need to get LE20B04SIM7600M22 now.
As there is no way to get it, I have bought another SIM7600E-H module.
The question is: how to get LE20B04SIM7600M22_210318 firmware from the same working module that is already in my hands?
