Based on your date Nov 26 2020, there appears to be an updated firmware at least. I haven’t had issues on SMS/MMS myself (other than MMS images never deleting when message is deleted). What were your SMS/MMS issues specifically? Do you use the Purism service or other service for mobile?
Purism support did not have me update any firmware. I have not done any firmware updates. Out of frustration I reflashed the entire phone, but that didn’t help, so I bought a new BM818 card, which did help. As I indicated elsewhere, I don’t know if the original BM818 card had a hardware or firmware problem. I hope this answers your question.
Yeah because newer modem card come with newer/diferent ADSP Blobs firmware which you got to working, but buying another card was not necessary, it was simply reprogramming a new firmware with Purism team @joao.azevedo
Any way i can test and flash the 2020 firmware for the A1 baseband 1 modem type (i am glutton for punishment)? For example the modem will never automatically connect to data after restart (with VPN selected to autoconnect - it does connect automatically with VPN off so maybe a new version of Network Manager, Modem Manager will fix this?), as well as experiencing random disconnects, i am wondering if this may help at even just a little would be good.
