MX4 baseband firmware?



  • I just read Flohack's post about updating the baseband-firmware on the N5. I use an MX4, but I have problems with it - specifically that it loses the connection to the cell network. That is annoying, but the coverage is poor. The worst part is that it doesn't automatically reconnect when it can. Sometimes it helps to put it in flight mode, otherwise I have to reboot it.
    When I go to work or on vacation the problem is completely gone.
    Back to firmware - does anyone know if there is a newer firmware for the MX4? I'm still using the one the phone shipped with.

  • @grisen I feel like I've been always experiencing this with my MX4. Unfortunately it works equally bad with Android (Cyanogenmod) as well as Ubuntu Touch.



  • A "dirty" solution would be to have the phone check the connectivity with 5 minute intervals. If it fails twice in a row: Reboot.
    Probably not good for battery life, but I could live with that. Any suggestions on how to check connectivity? Just pinging 8.8.8.8 won't work as wifi works ok. How about cron? Can I run regular cron jobs?

  • @grisen What's you MX4 radio revision? Mine is
    Revision = MOLY.LR9.W1421.MD.LWTG.MP.V6.P11, 2014/09/10 10:16
    I've googled a lot without finding something usefull like it's available for the N5. I only found a promising FlymeOS v6 update ZIP file. There are some .IMG and .DAT files inside but nothing related to radio like the N5...



  • Where do I find the firmware revision?

  • @Grisen , right in the phone, switch off radio (airplane mode) open terminal (install it from Openstore) and run
    /usr/share/ofono/scripts/list-modems
    Look the line "Revision"
    ...switch on radio ;-)

  • @wilfridd I have the same revision as you. However, I created a cron job running every 5 minutes. All it does is ping 8.8.8.8 once. This seems to "cure" the problem - maybe it prevents the phone from entering a deeper power save state. It didn't loose connection yesterday at all with the cron job running, which is unusual. If the problem comes back, I expect the ping will time-out, and I can use that to trigger a reboot. There may be better ways than ping to detect the lost connectivity. Some of the other scripts in /usr/share/ofono/scripts/ look interesting...

  • Too good to be true. After five days, it lost the connection again, and as usual it couldn't automatically reconnect. I looked at my script output, and I noticed that when there's no 4G connection, it doesn't run the cron job every five minutes. So somehow it's reversed - it's the baseband chip that keeps the phone awake. I'll try with just 3G - maybe that'll work.

Looks like your connection to UBports Forum was lost, please wait while we try to reconnect.
