Updated modem on Meizu Pro 5.
-
I replaced my Pro5 with an original Ubuntu Touch device and have had no trouble with LTE network connection at all and its on S333_M86_20151002_CNOPEN_MZ024. I have not thought about upgrading it until I saw this post, but I don't think that I really need to.
I do think that LTE coverage has improved a lot since last year so that might be the improvement though?
-
@halucigenia This is improvement in a matter of a 2 weeks, don't think the coverage could get upgraded that fast and everywhere. So it's definitely a cause of updated modem firmware in my case.
-
@Stefano Btw, my observation is that the combo sim slot is working better than the normal one. Try to switch , maybe it solves the network issue ( but no SD card then )
-
just to add to this, after every OTA or manual flashing this needs to be redone again, as the update overwrite it.
-
@Stefano Thanks for the info, I did not realise that.
-
@Stefano Thanks for the tip, i might dig back my Pro5
-
@Stefano we are not flashing any firmware, why do you think its being overwritten?
-
@Flohack On Pro5, modem and other drivers are part of the lxc container fs and not dedicated partitions which might be why it gets overwriten?
-
@Flohack I don't know. But after manual update with ubuntu-device-flash to edge channel that I was testing, I checked the modem version and it was changed back to previous version. I reflashed stable again and checked the modem, stil the same, so I had to reflash the modem. Then I checked the modem version and it was again the new version.
-
Mine remains the same (new version) when I update weekly from the rc channel. Only when I changed the channel I had to reinstall it.
-
@mihael that's interesting, so how is that happening? Why when we switch channels the modem version gets overwritten and while only updating daily or so (on devel ) it doesn't? Can someone explain, cos I obviously can't.
-
@Stefano I also once changed the baseband following the guide on this forum but I didn't notice such an improvement. To be honest I didn't test it so heavily so thank you Stefano to have made us aware of that, I'll certanly flash it back and pay more attention to the behavior. As a final comment, I'd say that if confirmed to be worth the upgrade, it would be great if the latest firmware would be included in the UT image.
-
@matteo yeah, test it and if stiil issues, try to use the combo sim slot, works better.
-
@mihael When I update (weekly) on the rc channel it downloads only tens of MB but when I change the channel it downloads hundreds of MB so I guess it overwrites a lot of stuff. When I update (on the same rc channel) many things remain the same: image writable, changes I made for the fingerprint and aethercast to work, mc installed, etc. That is not the case when I switch the channel to stable for example.
-
@Stefano Is the modem flashed into a certain partition with fastboot?
-
@Flohack Not by fastboot, by the method mentioned in the first post, there is link to that post. But, I also flashed modem couple of times with flashable zip that contained a new/different modem firmware and by checking the modem version after that, it was changed. So, yeah, different ways of doing it.
