On my modem (Quectel EM12-G firmware EM12GPAR01A09M4G_MSFT) IPV6 protocol not work and mobile network connection is unstable, randomly disconnnects. Same situation on Windows and Linux host computers.
Modem EM12-G is powered from external power supply - no voltage drops or glitches on high current consumption.
Mobile network operator - Mobile telesystems OJSC (Russia).
Another modem (huawei e3272) works stable with same SIM-card, and IPV6 protocol works fine.
Can everyone send me a link to latest firmware update for EM12GPAR01A09M4G_MSFT to get more stable mobile connection and get IPV6 protocol work?
Thanks for fast reply.
This firmware is not possible to flash to my modem (EM12-G MSFT).
I tries to flash your version, also tries earlier EM12GPAR01A18M4G and EM12GPAR01A17M4G, all unsuccessfull.
I tries use for flashing following tools: QFlash_V4.18, QFlash_V4.19, Quectel_Customer_FW_Download_Tool_V4.48, all unsuccessfull.
In all cases i was get same error: “FAIL,DL_Firehose, Time out!”
Maybe “MSFT” modem has different hardware configuration, and needs special firmware (e.g. EM12GPAR01A14M4G_MSFT) and another flashing tool? Can you give me links, please?
Thanks for last version of Qflash tool.
But flashing with this version is unsuccesfull with same error “FAIL,DL_Firehose, Time out!”.
Firmware path is “D:\Download\EM12GPAR01A21M4G_01.005.01.005”, that is not too long.
Maybe modem EM12-G MSFT requires a different firmware update tool or specific firmware version?
