Is there a possibility to make firmware for the internal 4G modem available.

When updating the routers firmware with latest v4.02 firmware the internal 4G modems firmware remains the same
with version M1.2.0_E1.0.1_A1.1.8 and does not update to latest M1.4.4_E1.0.3_A1.1.8.

Can you please share mini pcie Bm806U-E1 4G modem's firmware (embedded with DWR-921 C3)

Note: I would be happy with 4G modems firmware version M1.4.4_E1.0.3_A1.1.8 because it is also found in routers like DWR-980, DWR-956, and DWR-953 apart from some later manufactured DWR-921 C3 models.
