Misc
Important note:
Starting from 17.09.2015 build the installer of chrono kernel is decoupled from a ROM installer, so e.g. no support for f2fs or dual boot with a default ROM kernel. In order to have all features of the universal kernel package you need proceed standalone chrono kernel installation.
Conversion EXT4 -> F2FS:
TWRP:
1) back up the system
2) find backup folder and rename system.ext4.win to system.f2fs.win, data.ext4.win -> data.f2fs.win etc.
3) restore backup of selected partitions
4) flash zip from attachment (chrono kernel is supposed to be installed)
CWM/Philz:
1) back up the system
2) format selected partitions to F2FS
3) restore backup of selected partitions
4) flash zip from attachment
Fix to GAPPS(GMS) FC:

Chrono...is that You?
C'mon, you should recover...re-co-ver, mate.
Btw - f2fs is WRONG, allright?

Yep Is there anything wrong? Just found some spare time to return to android development.
UPD. while I'm on the treatment, there is almost nothing anything to do for me... Just wanted to bring this ROM up before I go to another city because of treatment.

For f2fs i have to convert first the rom with the script or i can install it as it is?

I caught myself that I haven't tested f2fs with this ROM(of course I've tested f2fs update itself). There installation with f2fs will be a little tricky, because /ramdisk/fstab needs to be changed(it can be updated after reflashing ROM, but this is not the best solution IMO). I will test it and report later.
UPD. Btw, kernel version line messed up a bit, just don't pay attention on this
UPD2. added info about f2fs to 3rd post.

With flufli's script f2fs installation was fine but i had system fc the first time, launcher's fc, camera as you have said and the rom was laggy for me even without installing any other app.
I went back to liquid so that's the only feedback i can provide

Well, updater_script of this ROM is quite different from CM11, and it was never guarantied(AFAIK) that it will work with another ROMs. For me mentioned in 3rd post way is working, and there are no FCing apps(besides of aforementioned camera).
and the rom was laggy for me even without installing any other app.

Note that for first 10 minutes media scanner is running in background, so there's nothing unusual that phone may lag in this time.

Well, after reading janice vanir topic I've found that GAPPS(GPS) FC bug will also appear there. This is related to -O3 optimization applied to binaries which are compiled in thumb mode. I haven't messed with optimizations yet(and Linaro GCC 4.8 is used here), but unfortunately for us, -O3 was already applied. Known fix for lollilop won't work on kitkat - it simply doesn't apply well, actually it can be applied, will try it later.

---

Then compile with -O2 and apply some non problematic -O3 flags manually

This isn't such simply. AFAIK, anything except -Os being applied to thumb code will fail. It's interesting to force ARM mode to check if it as well fixes issue, but first I'll try out removing forced alighment code. I have too slow internet to upload(or rather - download) new build in near time, when applying just one fix probably can fit in few blobs.

Test fix to GAPPS FC bug. To apply reboot to recovery and copy files to /system/lib(make sure you have backup of original files!). Please test it and report if it's working.

Well done! This works for your CM11 05.05.2015 (Running Google Play services 7.5.74 (1997312-034))
The idea to use other/older libjavacore.so was known but not to change libjavacrypto.so also. Which is obviouly if I think about it once more
As you know me I made an installer zip of this. It is not my work actually - I only changed files, added codina and CM11 checking and added deinstall routine for my old init.d fix.
You can use it also (of course) if the init.d fix was not used...
This will do the following:
Deletes init.d 50gmscache (if installed)
Deletes cache folder of gms (will be build new automaticly)
Makes backup (*.so.bak) of original libs
Copy working libs over the original ones.

---

Okay, good to know that fix is working. Now I can publish patch which is backport of well known fix for lollipop https://github.com/ChronoMonochrome...mmit/a2d116008d15c3db373ad372ab37548058926bfc .

Good work, Chrono
I saw that in rom preinstalled r3 kernel
Is there an update already or it special version for Vanir?

There is an update(read changelog in 2nd post), but I haven't pushed it because I need to deal with some changes in kernel installer(and in build script, in particular) and make sure that they works properly.

Thank you
:good::good::good:

upd: kernel used with this rom is the best.
I made fatal mistakes by flashing nonrelated chrono's ones.
I was SO WRONG flashing latest one instead of testing included one.
Definitely, kernel used there is really fit for this rom.
Awesome(some tweaks are still needed, but, damn, it is really, really awesome)!
Kernel we have there still can use latest chronokernelsettings(MANY customization are needed to get totally great results, but CKS + perfctrl used together are capable to push a2 to the max, imho).
This is awesome rom.
Small advice - add these to init.d with 755 permission, reboot:
http://speedy.sh/FVaw2/init.d.7z
Then you can optimize your system even more with chronokernelsettings + perfctrl(do NOT overwrite init's settings there).
Then - apkopt - list of apk's to being optimized - soon(check fuc.kin dialer gain)...
Then - media.scanner, any wrong id tag may result in batt drain(imagine >500 mp3 files with wrong id tags, then imagine 1500 files with wrong tags on extcard and media.scanner working)...
Yup, it can DRAIN your battery without reason...
F'ed up tags of your music/vid files may break your nice, flatline batt usage, too.
Another story - ex-ter-nal music player/vid player...
And so on, so on...rom itself, or kernel will NOT help you, if you are not aware how andorind is working.
Anyway, good luck....feel free to ask.
But maybe tomorrow, now i am drunk, allright.
Chrono, thank you.

Not enough space on /system
It seems apps that require to write some data on /system (like AdAway or Mount2SD) are not working correctly after f2fs conversion. Error message says "there is not enough space on /system". I wonder if anyone experienced the same or is it just me messing up at a step?
