Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Never thought of that... how can I do it?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I did the jump from 2.0.1.11 to 2.0.4.13.
Unfortunately, I have a massive battery drain since then. One minute display on and surfung the web equals 1.5% of battery.
I don't see a problem with Lighthouse or AIDA64. It drops to 3...8% CPU. 3 cores are at sleep most if the time.

Any hints what might be wrong?

Cheers!

After answering, take a look at your screen - the buttons are more than usual and one of them is switched on... :)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I know BT us not useable at all for phone calls. Music seems to sound fine on BT. Even without BT, phone call audio just not usable for me. Speaker phone is doing the same thing also. My end, it sounds great. It's always the other end having the issue.

My colleagues and clients are complaining too much. I am booting back to android for the time being for my daily use.

I love to use Sailfish OS, so I am anxiously awaiting for a device with good/high end specs (at least 5" size and 2/3GB RAM, etc) and fully functional on USA LTE, preferably T-Mobile. Who knows if that's ever going to happen and who know how long I will be interested. A cheap device with odd OS makes it looks like a cheap OS. We need a device that will make Sailfish OS elite.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

OnePlus X? :)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Is it really usable and stable with Sailfish OS? How is the phone call audio with and without BT and speaker phone? I make a lot of calls on the road (I know, I shouldn't!) , so phone calls must be good for me and the caller.

Nexus 5 working great for everything else, but not quote good for the phone calls for me.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Phone calls are fine, good quality, BT works, including PBAP (with 2.0.4, there were problems in 2.0.3.x). The only issue I have is the home screen freezing, but that's a problem with all phones with 2.0.4. Stopping LPM minimizes that. BT is disabled after reboot, you need to manually start it (adaptation problem).

Now that the browser has newer engine it is much more usable and I don't miss the Android apps from Jolla One so much.

Camera works rather good, though sometimes after update it doesn't show the viewfinder for some reason - a restart fixes that. There is also a patch from kimmoli, that enables 4K for video, didn't use it yet.

Can't be used with multirom though.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Finished update of my daily driver partition today. I didn't had a single freeze with LPM enabled, and i use the Sneak Peek options often, because of the double tap to wake.

Isn't kimmolis 4k patch only for the OnePlus X?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Yep
:)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Thanks for the detailed reply Bundyo.

I am still stuck with Whatsapp, so I don't have much choice, yet. That is the only Android app I have to use. Now that I have used LTE on Nexus 5, it is hard to go back to 2G on my Jolla 1.

Sailfish 2.0.4 also seems very good. Once of the most important feature I was missing was native conference calls and it seems to work great now on Jolla 1.

Well, wait I guess for a good device to come out. :)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Damn, the OTA update instructions from the first page differ from the one in the wiki regarding the repositories to be used... New try, new luck:-)

Edit Update to 2.0.4.13 took hours, not recommended. I had to drop adaptation0 as of pattern issues.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

This might be of interest to anyone installing SailfishOS roms.

I've been playing around with a very good Moto G (falcon, 2013) SailfishOS conversion made by PiggZ.

Unfortunately GPS was not working at all, even when the main thread in XDA forums said it should.
Eventually I got it fixed by installing normal Cyanogenmod, and making sure that GPS was turned on and working, and then restoring a backup of my previous installation of SailfishOS on top of it.

It is quite possible that GPS had been never used with the Moto G device I had acquired, and Sailfish probably couldn't trigger it without Android proper first activating it. So if you get your hands on Nexus 5, make sure to check that all radios, gps and sensors have been activated before you flash it to Sailfish OS.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Do you mean, if used as a pristine device (never turned on) and if SFOS is installed directly to it?
Or do you mean, that when CM is flashed to the device, turn it on and use it for a while before flashing SFOS on top of it?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I mean that if you use pristine device and then install SFOS (custom Cyano+SFOS) on it, GPS may not work, unless you have at least once started it up with proper Cyanogenmod and set up GPS.

Moto G device I have has been in used as a loaner device for a very short time while the original phone of the user was in repair. It had stock Android Kitkat from Motorola when I got it.
I flashed it directly with custom Cyanogenmod and SFOS, both by PiggZ, and then started the phone.

It is quite possible that GPS has never been enabled before. And definitely it has never had cyano on it before, as I had to unlock its bootloader with an unlock code requested from Motorola.

I'm not sure which would have been more important in my case; turning GPS on in stock Moto ROM before flashing it, or turning it on on "stock" Cyanogenmod, like how I now fixed it.

I just remembered that sometimes custom ROM makers suggest turning all features on before flashing them. I tried that as a last measure to get the GPS fixed, an it really worked.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I don't see my backup in the restore menu after copying the vault.tar file to /home/nemo. I've tried to use "Restore from memory card" using an OTG cable, but it doesn't see it there either. How can you restore on the Nexus 5 if it doesn't have a sd card slot? Is there a way restore the SailfishOS backup vault.tar file without using the restore app, but perhaps via CLI?

edit: I just figured it out. From CLI:
Then go back to Settings > Backup and I can now see my backup.

It didn't restore my customized Ambiences. Seriously? Customizing the sounds on each Ambience is a PTA. That's the main reason I did a backup.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

This is a very good observation and a solution is appreciated.

Unfortunately since 2.0.2.x backup/restore from settings needs an sd card or some dubious cloud services. Backuping works in the sense that a tool/command called 'vault' gathers different data to the .vault directory, for instance your gallery pictures, which you will also miss.

We need a kind of virtual sd card or all commands the settings app is triggering using vault. How sailfishos recognizes that an sd card is 'inserted' when backuping / restoring using settings?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

For me, it seems that the main camera has a problem with updating the viewfinder, it takes at least 3 seconds before it updates the viewfinder with the correct image.

Front camera and main camera video mode work fine though :(

I'm not sure if it's with the OTA update or no, but everything known to work works well, except this camera bug :(

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Have you tried reinstalling the camera app? Or try cameraplus from openrepos.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I'll try reinstalling the camera, but I don't know how. It's just in the Jolla store right?

Cameraplus works well, although if I remembered, it's always in landscape?

I accidentally left my N5 at home, I'll double check when I get it again.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I think it is from terminal.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Just tried, and it's still the same.
I think I'll stick to Cameraplus for now :)

Has anyone build a kernel from source? I compiled it and it is booting, everything seems to be working except wifi...has anyone a solution?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

As this is the thread for SailfishOS 2.0 Nexus 5 CM12.1 I suppose everyone who has built it has built the kernel from sources :D
Which version did you build? My kernel is 3.4.0-cyanogenmod-g0aac178-dirty with a slightly modified defconfig.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I used the source from the mer-hybris github It is 3.4.0-cyanogenmod-something. I took the defconfig from /proc/config.gz and used the linaro toolchain to build it. I must have been missing something, because wifi doesn't work.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Damn, tried to compile ElementalX kernel for use with Sailfsh, finally i got it booting, but the touchscreen is not working...

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Finally got it all working. Kernel boots and wifi is working too.
Let's do some undervolting.

Next step: Integrate some CPU governors.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Hey mautz, what did you do to get that kernel running? I've long wanted to do some undervolting on sfos. If you wouldn't mind, can you point me in the right direction? Thanks!

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Hi, sorry for the late reply. I'll publish my kernel in a few days. I'm still trying out some features.

If everything goes well, i'll publish the source on github and an flashable zip file here.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Interesting features. Do you have already tested battery life or is it achieved by underclocking the cpus?

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I've gotten a little better battery life on 2.0.4.14 by setting my max scaling frequency to around 1.7GHz and setting the governer to ondemand. Still does the huge 1% drain or so per few minutes with the screen on though. Really wish I could figure that one out.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I am testing at the moment. I added a few features from the blu_spark kernel:

- blu_plug cpu hotplug governor
- blu_active cpu governor
- Simple GPU governor
- USB fastcharge
- Undervolting

I hope to publish the kernel today or tommorow, than you could test it yourself, but don't expect a huge improvement in battery life.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Excellent, I look forward to testing it. I'd be happy to provide feedback as well. Any improvement is improvement. Can anyone speculate as to what might be the source of this battery drain? It only happens when the screen is on, so my thought is maybe a polling interval ramping the CPU cores up and down too rapidly, possibly the governor trying to anticipate user input to reduce UX lag? I dunno, top isn't much help. Everything looks fine while ssh'ed into the device with the screen off...

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Here we go...

The source can be found here:

https://github.com/mautz-kernel/SFOS...-custom-kernel

Just use the 'SFOS-hammerhed-custom-kernel_defconfig' to build the kernel yourself or modify it if you want.

And here's the Zip to flash the kernel with the recovery:https://www.dropbox.com/s/csq3qd81ci...ernel.zip?dl=0

If the output of

Code:

---

uname -r

---

is not

Code:

---

3.4.0-cyanogenmod-g0aac178

---

you should not install this kernel, because the wifi modules will not load. You'll have to compile it from source and change the localversion string in the config file!!!

This kernel is based on the source of mer-hybris.
Added features are taken from blu_spark kernel developed by eng.stk. More info on XDA.

Added features:

- Undervolting
- blu_active governor
- blu_plug hotplug governor
- simple GPU governor
- USB fastcharge

More to come...suggestions welcome.

If you are using sfdroid, you can use apps like Trickster Mod and SetCPU to change settings. I recommend Kernel Auditor, it lets you change the Hotplug settings too.

If you want to use blu_plug as your hotplug governor, you can disable mpdecision(default hotplug governor) via Trickster Mod or rename mpdecision to mpdecison.bak in /system/bin folder and restart.

Of course all settings can be changed via sysfs.

Undervolting can be done by changing The blu_plug hotplug options can be found in GPU settings are in The governor can be found in the pwrscale/trustzone folder.

Fast charge can be enabled by changing the value from 0 to 1 in And make a backup of your device, i'm not responsible for bricked devices by flashing this kernel.

Feedback is welcome.

@mautz

Fantastic work, friend. I'll install shortly and report findings in this thread. Thank you for your work and effort!

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Installed and running, mautz!

This is on 2.0.4.14, haven't had any glitches with a -75mV global undervolt (manual editing, not using sfdroid or any of the apps) on a PVS 2 binned SoC. Running the blu_active governor. Experimenting with GPU and other settings now, and will post my “optimal” settings for anyone willing to try them.

Again, excellent work @mautz! I love this community.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

Quick issue, unrelated to mautz's kernel:

Has anyone noticed that jolla-xt9 is missing in 2.0.4.13/14? I can't get it to install via pkcon to save my life. I've done zypper ref -f and pkcon refresh after disabling adaptation0, etc., but I've had absolutely no luck. I didn't have it installed on 2.0.1.11 this time around before I jumped to 2.0.4.13 then to 2.0.4.14.

Any help would be appreciated. Or even an .rpm lol.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I had to download the file with my Jolla1 and copy it to the N5. But i can send you a copy later...

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

That would be great! That must be a recent change, as a few months ago on my first 2.0.1.11 install on the Nexus 5, it went through without issue.

Either way, just let me know when you have it available. Thanks! :)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

I send you a message.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview
 

First: THX a lot for all the work mautz!!!

@deprecated
I do also have a 'PVS 2' CPU, but I can only get -50mV out of it. Otherwise I get instant freezes. My setup would be 2.0.1.11 on multirom.

I see some improvements in powertop, but I definitely prefer (always have) the 'conservative' governor over 'blue_active'. I see much better stats in powertop for idle state. I get low peaks of +/-200mV. When I change the governor to 'blue_active' idle mV usage is 460mV and more.

I do have some hopes for the GPU settings... So I stay tuned...
