Hi, my Puli has the built-in Quectel EG25-G modem. According to the AT command "AT+QGMR" it has quite an aged firmware:
EG25GGBR07A08M2G_01.001.01.001
Is there an easy step by step manual on how to upgrade the firmware of the modem?
Hoping to overcome the issues with my Telekom Germany SIM, which refuses to register with the network. I found newer firmware references (e.g. EG25GGBR07A08M2G_30.006.30.006) which specially seem to tackle those issues: https://github.com/Biktorgj/quectel_eg25_recovery/blob/EG25GGBR07A08M2G_30.006.30.006/Quectel_EG25-G-GB_Firmware_Release_Notes_V0708_30.006.30.006.pdf
