[HowTo] Update baseband firmware

HendriXXX

@tupp, boot your phone to fastboot mode and look for "baseband" or open terminal and "cd /usr/share/ofono/scripts" and run "./list-modems". Look then line "Revision".

@hendrixxx
Thank you!

The only revision number that I could see (I could not scroll up in the terminal) matched the current one shown above for Android 6.0.1!

By the way, can anyone recommend another Ubuntu Touch terminal emulator? It seems difficult to navigate the stock terminal (no arrow keys, and I can't figure out how to hide the keyboard).

Thanks!

HendriXXX

@tupp you can hide keyboard by swiping down. and you can get arrow by press and hold "keypad" button and select "SCR" then slide top panel to right and there you have arrow keys.

@HendriXXX
Thanks for the terminal tips!

However, I am still curious if anyone likes other terminal emulators for Ubuntu Touch.

HendriXXX

@tupp no problems! Happy to help!

Ps. You can scroll terminal screen up and down by swiping two fingers on screen.

@hendrixxx swiping down? never works for me

For anyone using the terminal quite often, it's easier to setup ssh on the phone. That way you can just run ssh phablet@<phone-ip> and use your desktop terminal.

Anyway, this is my output: Revision = M8974A-2.0.50.2.30

Looks like I should benefit of this firmware upgrade, correct?

Sidenote, this was also in the ouput:
Manufacturer = Fake Manufacturer
Model = Fake Modem Model

This is normal?

Yes. When keyboard is visible put your finger on it and swipe down. Keyboard will go down (hide). Very useful IMO.. I use that all the time.

Probably, there is no need to upgrade, as you seem to already have the most recent version (see image in OP showing file "radio-hammerhead-m8974A-2.0.50.2.30.img") installed.

flohack

@tupp Yeah there is no younger one on Android pages right now I took the latest...

Good to know! Thanks!

I checked and I had radio-hammerhead-m8974a-2.0.50.2.29, so I updated to 30 following the @Flohack instructions.

Everything seems to work as expected but the WIFI hotspot is still not working. It starts OK, but the wifi signal is not seen by nearby devices. Then when it is turned off, wifi does not work any more in the Nexus 5. A reboot is needed to get it back.

I will report on battery life if I see any change.

@Flohack Thank you for help. UBports rocks.

After some days of usage, I can't see any improvements in battery life with the 30 version. Maybe the 29 version which was the one I had is not so different.

HendriXXX

I have been using latest baseband over week now. Battery now lasts maybe 30% longer in my case. Much better thing is that there are no network dropouts anymore. Before a had few locations where it was almost impossible to use mobiledata, but now also those locations works very well.

I did some testing with powerstat. "3g ON" it almost doubles consumption.

Wifi on:

3g on:

I also tried to check system wakelocks but N5 kernel doesn't have "/proc/timer_stats" support. It needs "CONFIG_TIMER_STATS=y" option compiled in the kernel. N4 has it already but N5 doesn't. I want to use "eventstat" to examine wakelocks but it wont work without it..

@flohack Thanks for a very nice and simple instruction.

I have a problem with the mobile connection after installing r3, and i hoped that doing this could solve the problem. Unfortunately it didn't. The problem is that mobile data connection does not work anymore after upgrading to r3. The "4G" icon comes up when enabling mobile data, but the internet connection does not work and there is only the loopback interface in ifconfig.

Do you (or anyone else here, of course) have any solution for this or any suggestions on how to debug it?

@hans1977se If your not on the development channel swop to that in update settings, update the phone and see what happens. That has fixed a few issues before. You can then swop back to whatever channel you want.

hans1977se

@lakota Awesome. It seems to be working again when switching to the release candidate channel. Thanks for your suggestion!

I'm surprised that no one else seem to have noticed this problem with the stable release. Or, i haven't looked throughly enough to find those who has problems.

Lakotaubp

@hans1977se No its come up on the forum before thats how I heard of it.Glad it worked for you.

hans1977se

@lakota Thanks. It's good that you have had time to follow what's going on here. I've been too busy to follow this great project these last few months, but i do have been using my Ubuntu phone without worries except for this one in the meantime of course.
