The latest version which runs fine on pollux windy is the20 nightly so i made an investigation on the changes at the 21 nightly.I have found 4 possible commits which could cause bootloop

1)The most possible cause in my opinion:This commit

It changes the status of se linux.Similar commits have caused many issues on other devices mostly because of mounting issues(just like some of the people who tested this commit,chek comments section on gerrit).Also it could be the cause why other fusion3 devices like xperia z have the same bootloop problem(this commit applies for all fusion3 devices)

2)The second suspect is this.It has to do with the previous commit.If something goes wrong with mount after changing state of selinux this is supposed to correct it.Again it applies to all fusion3 devices.

3-4)The greatest outsiders.This and this commits.These apply to all devices with snapdragon s4 pro.Our devs are very experienced but when merging new linux kernel version something can go wrong

There have also been other change which could cause issues(like bionic changes) but they apply to the whole cm(dalvik config changes for example) so there would have been problems on a huge scale of devices.I hope a dev notices that post

By swapping the boot.img in any of the nightlies after 20th Dec for the file in 20th nightly, I can get it to boot but Wi-Fi can't be toggled on. Any ideas on that? Here's hoping they fix the issue.

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] pangiotis24:
The fact tha we don't have wifi if we install the older boot.img can may be explained by this.The fact that it boots with the older kernel underlines what i was saying.It is kernel side problem so it goes again to the 4 suspects i mentioned on my previous post.Unfortunately i don't have time to compile and test how it goes without each of these commits to find the cause
[Xperia Tablet Z Original Android Development] john.r.raynor:
This really is a fantastic Project. I have installed build no 248 and have not had a single problem (in the actual running of the rom or its apps) in the two or three weeks since. Very stable, nice and quick and with ART working with no issues. My only question is the following: how do you set the default SMS app? I have no SMS working. I have read that this needs to be set in 4.4 but it's not in messaging app settings or hangouts or in more section of wireless and networks settings in settings app. Otherwise, seriously top notch effort, I am very impressed with this rom and love it. Keep up the fantastic work!

[Xperia Tablet Z Original Android Development] neonlite:
yeap, bootloop with latest nightly too. FXP252-cm-11-20131230-UNOFFICIAL-pollux_windy
[Xperia Tablet Z Original Android Development] Charsher47:
Are you guys getting bootloops on the FXP and the official CM11 nightlies?

I did a clean install of 12/27 official nightly and still no bootloops... Everything is working fine except for bluetooth. Flashed on twrp with PA gapps FWIW
[Xperia Tablet Z Original Android Development] scoobyjenkins:
I'm using cwm which I originally flashed using the boot.img from an earlier build, it's updated itself since. Perhaps that has something to do with it. How did you install twrp? I can only find the dual recovery by Philz and last time I tried, Goo Manager app wouldn't get as far as downloading a recovery, just kept sticking!

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] Charsher47:
Just got it from their site and followed the instructions there: http://teamw.in/project/twrp2/185

[MENTION=4728887]scoobyjenkins[/MENTION]:

Any luck with something else than official .20? (I mean only officials -nightly).

I'm still @ .20, updateing with CM updater to .29 gave bootloop @ moment when applications was optimized (cache).
[Xperia Tablet Z Original Android Development] scoobyjenkins:
I haven't tried anything other than official nightlies, they all gave me a bootloop, so restored my nandroid of 20th Dec nightly. I'm going to try install twrp recovery later and see what happens when I try update!

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Thanks man, I came across that page before as I wanted twrp since I got the tablet but didn't dare! But you kindly gave me the link and it was super easy with terminal emulator. I just made a backup and flashed the latest nightly (30th Dec), hey presto - it worked! So now I have my recovery of choice and can update. Awesome. Anyone else having bootloops should check out the link to install twrp (I installed latest 2.6.3.0) and enjoy!

[Xperia Tablet Z Original Android Development] Charsher47:
No problem, I prefer twrp also. This is the 3rd rom I've seen where flashing using cwm messes something up.

[Xperia Tablet Z Original Android Development] pangiotis24:
So it works but only on twrp?hmmmm interesting.i will try it out
[Xperia Tablet Z Original Android Development] scoobyjenkins:

Tapatalked that shiznit.
[Xperia Tablet Z Original Android Development] Jequan:
Yep works. Just tried with latest twrp.
[Xperia Tablet Z Original Android Development] pangiotis24:
installed and works ok except of bluetooth.to test gps you should set on location to high accuracy and test with an app like gps status if it locks.otherwise maps can find your position from network locationing.I will test gps and report back later but i don't think it has been fixed
[Xperia Tablet Z Original Android Development] scoobyjenkins:
Ah fair enough, thanks, will test later also.

[Xperia Tablet Z Original Android Development] SnZ:
same BT + GPS (gps status, +high) are broken.

How do i report this to dev's?
[Xperia Tablet Z Original Android Development] pangiotis24:
The maintainer is supposed to look at this thread regularly so that he can fix the reported issues.After andrew(entropy512) left cm for omni there is little interaction of the users with the devs.There is just a post telling "on the next nightly the issue will be fixed".Anyway let's give him some time.These days he may be on vacation

[Xperia Tablet Z Original Android Development] Riekr:
Correct me if I'm wrong but recovery is bundled with kernel so changing the recovery will change kernel too explaining the same results as flashing a pre 20dic nightly kernel.

When flashing another cm release the recovery will be maintained as per updater script but kernel will be a fresh one and if I'm correct or if cm won't fix the kernel the tablet will bootloop again.

I've only read that on other threads so I'm not 100% sure.

[Xperia Tablet Z Original Android Development] pangiotis24:
Nope.if you read on twrp site they have a method where only recovery is replaced and not the whole kernel.you can test it on your own.install twrp recovery from twrp site and then flash a cm nightly(as it comes with cm).you will notice that after flashing the nightly you will still have twrp
[Xperia Tablet Z Original Android Development] Riekr:
That's true when you flash cm but when you flash twrp will it replace the kernel?

---------- Post added at 08:21 PM ---------- Previous post was at 08:08 PM ----------

The verdict on the bluetooth problem:selinux.It causes more problems than it solves.If you havent noticed after the 20 nightly se linux has been turned from permissive to enforcing.I have the opinion that this causes a kind of conflict with cwm so that it bootloops if flashed with cwm.But the crap is beyond the limits.We have noticed that bluetooth is not working.I digged into logs and guess what i've found:selinux blocks bluetooth.So here is the solution(AS CM 11 DOESN'T GIVE US THE OPTION TO CHANGE IT'S STATUS FROM THE ABOUT MENU AS IT DID ON PREVIOUS VERSIONS):Install selinux mode changer app from playstore or from xda and turn selinux to permissive and voila.bluetooth works.

MOD-EDIT:: No swearing please....

The gps issue is more complex.The guy who fixed it the previous time tries to fix it now
[Xperia Tablet Z Original Android Development] iestyn99:
That's what I did too, but still I get bootloops.

Today, I've tried flashing the boot.img once again, extracted from the latest CM11 update, through fastboot. Then installed twrp with the app "TWRP Xperia installer", which results in a working twrp 2.6.3.0 recovery. Then tried to install the 20140101 update through the built-in cm-updater. It does this indeed using twrp and not cwm. Result: the installation goes through optimizing the apps but gets stuck at ""Finishing installation" and then goes into bootloop.

Manually flashing the 20140101 update in twrp gets the same result.

I really don't know what the next thing would be to try...
[Xperia Tablet Z Original Android Development] pangiotis24:
weird.everyone else didn't have any problem.maybe using cm updater messed thing up.That's what i did:being on 20 nightly,installed twrp from here and then installed the latest cm nightly.Anyway even if this workaround does not work the new nightly will include a new cwm version so you will be able to test(when it is released flash the boot.img from the nightly,then boot in rwecovery and flash the nightly)
[Xperia Tablet Z Original Android Development] sailinahobie:
Rooting for a solution (scuse the pun)

This is really frustrating, I'm having the same bootloop issues with CM 11... I have tried the AOKP 4.4 Rom (second listing in the "Original Android" thread) It installed without a problem with TWRP. But I'm really looking forward to CM 11, with the richness of features CM includes.
[Xperia Tablet Z Original Android Development] zeus2602:
Stable?

Is the new one stable?

Or still a bootloop...
[Xperia Tablet Z Original Android Development] iestyn99:
Still a bootloop for me with the 0102 version I'm afraid, even if flashed with twrp.
[Xperia Tablet Z Original Android Development] hav0c:
Running nightly 01-01-2014 flashed using CWM on Pollux and all is working well. GPS and Bluetooth are working just fine. Streaming music via my Bluetooth audio system works and GPS gets a fix within 20 seconds. No bootloops whatsoever. Thanks a lot to the OP!
[Xperia Tablet Z Original Android Development] andymg350:
Anyone notice double tap to sleep option in interface > status bar with latest nightly? Very nice just wish we could get double tap to wake now!
[Xperia Tablet Z Original Android Development] pangiotis24:

I know its been the holiday season but that's 2 weeks with broken nightlies and no indication the devs are even aware. Is anyone out there?
[Xperia Tablet Z Original Android Development] andymg350:
theres no issue for me with any nightly since before december havent encountered any bootloops or anything and ive been running cm11 since it came out, but i did originally flash from cm10.2 to cm11 and i am also using XZDualRecovery.
[Xperia Tablet Z Original Android Development] JoeSzymkowicz:
I've tried installing several cm11 nightlies and all bootloop for me. Is there a specific firmware that needs to be flashed before trying to install cm11?
[Xperia Tablet Z Original Android Development] gerzii:
i have the actuall cm11 from cm installed and it works fine :=)
[Xperia Tablet Z Original Android Development] scoobyjenkins:
It seems that after the 20th Dec 2013, something changed that caused issues with Pollux Windy, a good theory was posted:

A few users seem to have avoided bootloops by using twrp, not sure why some cannot. I installed twrp using the instructions from their site and used the app mentioned above to fix Bluetooth by changing selinux to permissive. All working fine for me, though GPS doesn't seem to work but I don't think that was working before.

[Xperia Tablet Z Original Android Development] coudu:
bootloop temporary workaround

The bootloop problem on some pollux_windy is definitely related to SELinux being set to enforcing (http://review.cyanogenmod.org/#/c/54324/). SELinux policies are missing some allow rules for windy and need to be updated for this problem to be fixed. I'm looking into it but I'm quite unfamiliar with SELinux that I don't use on any of my linux machines...

A temporary fix for this problem is to set SELinux to permissive again until root cause is found.

To do so you can compile a bootimage with SELinux set to permissive in the kernel cmdline (the same as it was in 20131220 nightly) but you'll have to reflash it after each update or even recompile it if needed by the changes made into nightlies.

A better solution is to use an init.d script to set SELinux to permissive on boot and an addon.d script to survive nightlies updates.

This is what the attached cwm zip I made is doing, it copies the init script 10selinuxpermissive to /system/etc/init.d/ witch sets SELinux to permissive on boot, and the addon.d script 51-selinuxpermissive.sh to /system/addon.d/ that backups/restores the init script before/after an update so you don't have to reflash the zip each time (only if you format /system manualy).

When the root cause will be fixed you'll just have to delete these two files to run SELinux in enforcing mode again.
[Xperia Tablet Z Original Android Development] Riekr:
did you forget the attachment?
[Xperia Tablet Z Original Android Development] coudu:
No I was quickly rebuilding it with the script in data rather than in system (more simple, no need for an addon.d script to survive updates) ;)

Edit: seems like system is the way to go because userinit scripts are executed too late and under certain circumstances you might end up with bootloop again (eg. lots of apps to dexopt/dex2oat after an update). I'll push a new zip soon

Edit 2: zip updated in previous post (using init.d and addon.d for better reliability)
[Xperia Tablet Z Original Android Development] pangiotis24:
I don't have time to test now but have you tested it prevents bootloops?I am the first who blamed selinux but it is strange that it affects only pollux_windy and not pollux
[Xperia Tablet Z Original Android Development] coudu:
Yes I firstly tested by reverting SELinux commit as it is well known to cause bootloops and I built a fully synced rom and it worked. Then I wanted to find a way to disable SELinux without having to flash a modified bootimage after each nightly or rebuild my own nightlies every day as I already does for my i9100 which doesn't have official cm11 nightlies and building for two device takes time...

pollux and pollux_windy have a slightly different hardware (eg. gps chip and the way it loads gps firmware...) and pollux_windy is the only device in fusion3-common that doesn't have LTE (others are Z/yuga, ZL/odin and tablet Z/pollux) so the windy might need different SELinux policies.
[Xperia Tablet Z Original Android Development] iestyn99:
Just flashed your selinuxpermissive zip and after that the latest nightly and I can confirm that it works!!!

You have made my day, coudu!
[Xperia Tablet Z Original Android Development] parapaul:

Yup it's working Great job! - Netflix fix

After weeks of frustration, the bootloop is fixed... Flash the Rom, then the Gapps, then the fix... It loops once (thought it was going to fail), then in second pass, it boots like a rock star. Only found one issue so far and that is that Netflix is broken... I found a fix for that located here

No idea if this actually the official CM thread, but this page lists the maintainers:

http://wiki.cyanogenmod.org/w/Pollux_windy_Info

kali-, jerpelea, codeworkx

Do they come here? Do they know it bootloops?

Eager to get on CM11 (I think, although happy with 10.2 regardless of the rotation bugs) but while I appreciate the efforts that have bene made to fix, I like using cmupdater without the hassle of plugging into a pc daily.
[Xperia Tablet Z Original Android Development] scoobyjenkins:
I've been able to use cm updater to download and update manually with recovery. I installed twrp following the instructions on their website linked earlier and used the selinux changer app also linked earlier to fix Bluetooth. Since then, updating hasn't caused me any issues.

I don't know about GPS because I don't use it. But I am now able to utilize CM11 ROMs with no more bootloop due to a fix that a member posted (Post #155) in this thread and Bluetooth works just fine as well... Obviously we need the Devs to include this fix for SELinux to avoid the bootloop issue natively, but at least the temp fix gets us up and running.

hey guys, for everyone with the bootloop problem, help is on the way: i've just fixed the issue with giulio cervera, and the change is waiting to be included in cyanogenmod (see status here: http://review.cyanogenmod.org/#/c/57422/). after this gets merged, nightlies will work on your devices again.

if you are a terribly impatient person (like me), then you can also grab my latest build from my server: http://www.vware.at/cyan/cm-11-20140113-UNOFFICIAL-pollux_windy.zip. just to be clear: this is a bog-standard cyanogenmod build with no modifications other than the selinux fix.

oh: and those who installed the temporary workaround that was posted here some time ago, do not forget to remove it ;)
