I purchased my LIMESDR MINI in April 2018 from crowd supply and received after 2 months.
Initially, I tested the SDR in LimeSuiteGUI_20171115_9c6611.exe, it was able to detect, load the default file, tx, Rx calibration was fine(green led). I was able to hear FM broadband reception using RTL SDR Console V3(version 3).
I thought to explore LTE base station software srsLTE and Osmocom BTS this month. To my amazement, the new LimeSuite though able to recognize unable to load default, Rx and tx calibration were failing(yellow and red led).
Rx calibration error message

Rest tests clock,FPGA, and LMS7002 are passing.
Needless to say, the same issues are coming when I try to run srsLTE.
I could not receive FM using the latest SDR Console software(3.0.10).
When I revert back to the older SDR Console(3.0), I am able to listen to FM station(the TX option is not active in this version so I can’t check transmission). It appears to me the firmware issue and when I try to update the firmware using latest Limesuite, the status says updates are successful but the SDR does not pass tx, Rx calibration, unable to load default settings.
I presume my SDR is working fine(at least Rx part which I could verify) but there is a firmware mismatch.
I request the members to help me to find out how I could update the firmware and will be able to use SDR Console first then perhaps I could use in LTE.
