Is there any ongoing work to update the ROM to cm 12.1? Are there any issues with the merging of code?

[Nexus 9 Original Android Development] simonsickle:
Yes official nightly builds started today, ending cm-12.0 builds at the same time. If a stable build is going to happen in 12.0 I'll set it up, though.

In other news, those who have modified their vendor partition with any "fix" for the 'internal error' bug will have problems with this nightly. To get around this error, flash the latest firmware from Google.

As always, any bugs or questions, post them up
[Nexus 9 Original Android Development] stavrinho:
Who ever install the 12.1 please tell us his opinion about the multitasking performance.

Thanks.
[Nexus 9 Original Android Development] Johmem:
I have been on CM 12 since I bought the tablet. I would like to switch to 12.1. Looks like I need new firmware and I would also like to not be encrypted anymore.

Can somebody please post some brief instructions for accomplishing this? I have been running custom roms on my devices for years, so I am fairly comfortable with fastboot, but I am far from an expert. Tablet is unlocked, ADB and fastboot work properly.

Thanks in advance
[Nexus 9 Original Android Development] simonsickle:
To disable encryption, flash a kernel with this disabled and fully wipe userdata. To flash the firmware download the image from Google. Then put the fastboot and adb binaries and dlls into the extracted directories (use 7zip for extraction). Use flash-all.bat for the flashing of stock firmware. Then fastboot recovery back on, and flash the 12.1 zip.

Be sure that you get the stock firmware before updating the rom. Else, your device may become a paperweight. Also I don't officially support unencrypt mods, so I'll leave you to find the appropriate kernel

Wipe everything again, including data and system, and flash cm 12.1 again. Then make sure you flash a 64bit gapps

Can I use elementalx kernel with this?
[Nexus 9 Original Android Development] kaatisu84:
I have not had any issues with this rom. Did a full wipe and flashed over an unofficial version. Can't remember if I flashed the vendor fix zip. But I am not having any crashes or force closes.
[Nexus 9 Original Android Development] bose301s:
Everything working well for me except gesture typing or swipe typing, I can't get that working in the stock keyboard, I made sure it was enabled in the settings and checked everything I could but I can't get it working, does anyone else have this issue?
[Nexus 9 Original Android Development] nartan:
Thank you, very much. This ROM works fine on my device, but the battery performance is not the best.
[Nexus 9 Original Android Development] simonsickle:
That's most likely Google Apps related. Check your battery stats in settings to find out the draw
[Nexus 9 Original Android Development] 9Lukas5:
I flashed today's nightly with 64bit gapps and (cause I couldn't remember if I ever changed there anything, I flashed the vendor image of the 5.1.1 stock rom)

For me everything is working fine

I'm on an old Unofficial 12.1 build from late June, will I be able to just do a lazy dirty flash to the new official 12.1? Anyone have any luck with that?

I did a dirty flash from 01. May cm12 build to todays cm12.1 build and hadn't problems :good:

I can't seem to turn of the sound on today's build. Any suggestions?

Edit: To clarify, I'm talking about the volume sliders not working. I can slide them all the way down but the sound won't turn off.
[Nexus 9 Original Android Development] simonsickle:
Nothing in device tree changed, so it's likely a bug in the rom. Give it a few days to be worked out.

Usually, it's fixed by the next nightly. Usually.
[Nexus 9 Original Android Development] blabla189:
does this rom have pie control?
[Nexus 9 Original Android Development] mattspew:
Quick question; when doing the OTA updates, do I need reflash gapps?

Edit: never mind working it out, no need to flash gapps, but I do need to reflash Xposed.
[Nexus 9 Original Android Development] thebeardedchild:
So I finally got around to trying to dirty flash the latest Official Nightly on top of a 06-23-15 UNofficial nightly. Upon rebooting I was getting constant play services force closes, so I had to restore the backup. Then I tried updating my firmware and vendor.img again to the latest from Google's developer page (LMY47X). I successfully flashed those in fastboot then tried the ROM again, still no luck.

I don't remember what Gapps I used in June, but I think it was a craiggomez or something... are those now incompatible with latest ROMs? Damn these play service errors on the N9 are annoying when I want to update my system. :/
[Nexus 9 Original Android Development] simonsickle:
Try flashing the cm gapps linked in the first post. Here is the procedure.

Backup

Wipe system cache and dalvik with advanced wipe. Only do these.

Flash cm latest nightly

Flash gapps from 1st post

Reboot

If there are still major issues, you need a full wipe. Sometimes going from unofficial to official builds /can/ cause breaking but I was able to go from unofficial to official without wiping with these steps.

If unofficial had any changes not in the cm code, it may be much more difficult for you too.

Boot loop on ROMs later than 20150810

I've been flashing CM 12.1 nightlies for two months or so now on my Nexus 9 LTE - without problems. But version 20150811 and later just hang at the Google logo - at the very beginning. :( Has anybody else experienced this?

Same here tamjan.

[Nexus 9 Original Android Development] erioho:
A silly question. I just placed my order on Nexus 9 LTE version, as an old Nexus 7 user, I can use CM12.1 easily as there is a dedicated build for it. But I can't find such a dedicated build for Nexus9 LTE, is that the build is unified for both WiFi and LTE, or no such build for LTE model? If that is a unified build, I will flash it immediately.
[Nexus 9 Original Android Development] simonsickle:
Just installed the build (8-12-15) and had a issue like youre explaining. Upon investigation, I found that if you let it sit for a while, it will eventually boot. I am investigating now and will push a fix in as able.

[Nexus 9 Original Android Development] FlickFlack:
I tested version 12th and 13th as update to 10th August version and also get stuck at Google screen. Version 10th backup restored and all is fine again.
[Nexus 9 Original Android Development] simonsickle:
It appears stuck but it's not really. Just let it sit there for a while
[Nexus 9 Original Android Development] FlickFlack:
Ok. I tested now version 14th august and after 5min the Google logo disappears and Android boots. It seems the Cyanogen bootanimation is missing at this step and so one could fear that it is stucked.

But most annoying is now that at each reboot the 5min Google screen is still there. Maybe it is only 4min, but after that also the Cyanogen bootanimation is shown for 1min and finally the boot process ends.

There is something "broken" in the startup. Version 10th august was fine. Could not say if 11th august is "broken" too, but 12th, 13th and 14th are "broken"
[Nexus 9 Original Android Development] simonsickle:
I'm investigating as able. Hopefully tomorrow allows proper investigation.

If anyone has the time, please flash the latest stock nexus image and make sure there are no further updates. At that point, flash cm latest nightly and see what happens. I believe it may be a firmware incompatibility in which case I'll just have to update some lines and throw some warnings. I haven't had time to do this myself yet as I'm in the middle of a move.

Anyways, let me know guys.
[Nexus 9 Original Android Development] FlickFlack:
Ok, I made the test. Just flashed the LMY48i factory images and boot the Nexus 9.

Than unroot it and install TWRP via NexusRoot toolkit.

After that start TWRP, wipe all partions but "internal storage" and than flash

cm-12.1-20150815-NIGHTLY-flounder.zip

gapps-5.1-2015-07-03-13-42.zip

After reboot I see Google logo for about 4 minutes and than the Cyanogen log for about 1 minute.

After that the app optimization starts. At the end a message box came up that "There is an internal problem with your device..."

I think this is a mismatch with latest vendor.img or so. I ignore that and configure Cyanogen as usual.

After that i tested a reboot and again I see 4 minutes Google logo, 1 minute Cyanogen and than the message box "There is an internal..." came up

Hope that helps. I will now restore my old Nandroid backup of 10th august version(only system and data, not boot!) and see how this goes.
[Nexus 9 Original Android Development] simonsickle:
Okay so I do need to put an update notice out for everyone. Will fix all that up today sometime. They're likely is other merged in code needing to be looked at, so who knows. Since everything still works I'm leaving nightlies to run their course.

If long boot times are an issue, don't install until I give all clear. August 10 is the last normal build.
[Nexus 9 Original Android Development] wash23:
I too have been having the unusually long boot time since the 8/10/15 build. The internal error message has been showing up for a long time before that but I have just dismissed it and continued without any noticeable effects. Something is definitely out of order. Thanks for your efforts in providing us a workable rom.
[Nexus 9 Original Android Development] simonsickle:
Update your firmware to the appropriate version as mentioned in the op. That's why you get the internal error message
[Nexus 9 Original Android Development] wash23:
I'll give it a go. Thanks!
[Nexus 9 Original Android Development] roaddaw9:
I can't get a nightly to apply. I download in Android GUI, tell it to reboot and apply. Once it does in TWRP, I go back to the Google logo screen at first boot and it seems to freeze. The only way I can get it to boot again is to go back to the 8/10 zip and apply that again. Any thoughts?
[Nexus 9 Original Android Development] fleischbanane:
I see some changes for our flounder. Does anyone know if 20150817 is save to flash? I can try it this evening after work.
[Nexus 9 Original Android Development] simonsickle:
Wait for tomorrow's build. There's a few things missing
[Nexus 9 Original Android Development] fleischbanane:
I've got an other general question: how is your performance on the Nexus 9 over all? I habe flashed ElementalX kernel before the first boot of CM to prevent the encryption but it seems to be slower than my Nexus 5. I have two users on my Nexus 9 and my Nexus 5, so I don't think this could be the reason.

Does anyone have any hints for me? Best kernel? Best settings?
[Nexus 9 Original Android Development] FlickFlack:
Thanks for your updates Simon. Will test also and report.
[Nexus 9 Original Android Development] Max128:
I can confirm this is not only wifi anymore.. i have a lte model and is working great..
[Nexus 9 Original Android Development] simonsickle:
Since I don't own one I won't mark it as official because I can't personally test. If it works though, feel free to use it with my blessing. No bug reports will be accepted for lte specific bugs though
[Nexus 9 Original Android Development] simonsickle:
Okay guys! So I am working on a proper fix but this commit causes the issues.

For those who build, you can cherry pick this revert. http://review.cyanogenmod.org/#/c/106264/

For those who just want it working, you can flash this in fastboot until I get the change fixed and accepted http://downloads.codefi.re/simon/revertedinit.img

Edit: flashify and dd also work but as always be careful
[Nexus 9 Original Android Development] FlickFlack:
As the problem is not fixed yet I tried to download the 10th august version, but it is not available anymore on the cm download page. Does anybody have a link to this version?
[Nexus 9 Original Android Development] FlickFlack:
Thanks so much. Needed the zip for my fathers new Nexus 9 and the zip that I stored weeks ago got corrupted.

I do not use the lockscreen. After DT2W my tablet is unlocked and rotation works fine.

[Nexus 9 Original Android Development] bosbode:
Yes I have the same problem as well. No clue what caused it.
[Nexus 9 Original Android Development] mattspew:
How often do you guys update? I generally only update every couple weeks or when I find an issue, still running a build from the 4th Aug.

I was about to update then noticed all the chatter about slow boots, missing boot animation and general buggy-ness. So what is the current state of this ROM? Should I just stick with my 4th Aug build?
[Nexus 9 Original Android Development] FlickFlack:
The last version I tested was 15th august and with this version the booting time is very long, but the rest runs well. I normally did not update so often, but I was new to CM 12.1 on Nexus 9 and so I also want to see how the update mechanism works. Currently I have all rolled back to Android 5.1.1 LMY47X images and CM 12.1 10th august nightly.

Could not say somehting to latest nightlies, but at least the boot time should still be unfixed, because the fix of simonsickle is still in review state.
[Nexus 9 Original Android Development] fleischbanane:
I'm on a nightly from 6th Aug and the last one I tried was from 21th but it still has the long boot-time. Will wait for the fix...
[Nexus 9 Original Android Development] Donald Nice:
Any news here?
[Nexus 9 Original Android Development] FlickFlack:
That is what I wanted to ask too. Not asking for any ETA, but I think it would be useful to have this long boot problem fixed, because users that are new to CM 12.1 on the Nexus 9 will get the feeling "it does not work" or "boot hangs".

It is also problematic that currently only nightlies on the official server are available that suffers from this problem. The last nightly(10th august) where the boot process was not broken is removed.

The patch/fix from Simon is still in state "needs code-review". No change there since 18th august. Hope they get fixed this, because I would like to test newer versions.
[Nexus 9 Original Android Development] tehlers:
and not for forget CVE2015-3825, which is fixed in cyanogenmod around 18th or 19th this month, what I understood.

So at the moment either long boot time or vulnerable...

[Nexus 9 Original Android Development] backdoorsanta:
Hi simonsickle,

The link for flashing code in fastboot in your last post is broken, do you have another one?
[Nexus 9 Original Android Development] gladiac:
Well, what I did was to

do a full backup in recovery,

flashed the new rom and after that

restored the /boot partition

This makes your system boot normally and lets you enjoy the newest rom (with older /boot-files and kernel). Of course, this solution is absolutely not recommended but it worked for me. Since CVE2015-3825 is not a kernel-vulnerability this should make your system more secure :).

If you experience weird problems after that procedure just revert back via your full backup and wait for a proper fix.
[Nexus 9 Original Android Development] mattspew:
So has support been dropped? Has someone gone on holidays?
[Nexus 9 Original Android Development] fleischbanane:
No, but a merge for the new Motorola Devices is in conflict with our device... and it seems the solution is still in work. I don't know if it's possible to do a build without this one comment.
[Nexus 9 Original Android Development] Donald Nice:
FYI: The CM12.1 Snapshot is released, no long booting problems, but updating from yesterdays nightly was not successfull for me.. Gapps crashing, also after wiping system und reinstalling snapshot + gapps. Hat to factoryreset.
[Nexus 9 Original Android Development] fleischbanane:
I'm still in the nightly from 6th and will try a dirty flash this evening. Thanks for the info. :good:

EDIT: Google Play Service is constantly crashin... hope a factory reset will solve it. Using the snapshot and latest Banks Gapps.

EDIT2: Clean flash solved all issues... seems it was absolutely necessary because the tablet is so much faster now. [emoji4]
[Nexus 9 Original Android Development] horst0815:
flashing todays nightly brings back the awful long display of the google logo at boot. about 4-5 mins, didn't happen with the snapshot though
[Nexus 9 Original Android Development] tehlers:
I would like to figure out the sporadic crashes I have already mentioned (one or two pages before). Nearly over every night, the tablet is in the mentioned state, only a reboot helps. This also happens with cm-12.1-20150901-SNAPSHOT-YOG4PAO237-flounder. I have the latest gapps installed, made a complete wipe also of /data (but of course reinstalled some apps via Titaniumbackup). No change.

What can I deliver to find the bug?

[Nexus 9 Original Android Development] dmantilal:
Flashed the SNAPSHOT to my N9. Working great, after the initial "I am too smart to read the OP" bootloop. Thankfully this device is damn snappy and software problrms can be fixed quickly.

I need to see if I can help with anything cyanogen/n9 related.
[Nexus 9 Original Android Development] fleischbanane:
The snapshot seems to work perfect. Would recommend this build to everyone until the problem with the nightlys is fixed.
[Nexus 9 Original Android Development] FlickFlack:
Are you using actual LMY48i or older LMY47X images(vendor etc.) from stock ROM?
[Nexus 9 Original Android Development] fleischbanane:
I didn't flashed the vendor or anything else since one or two month, so I think it's not the newest one from LMY48I.

Can check it tomorrow and can also try to flash the newest vendor and bootloader and report if I have any issues.

EDIT: I extracted both Images and it seems the vendor files are the same.
[Nexus 9 Original Android Development] FlickFlack:
Thanks for checking this. I think I will update my Nexus 9 in the next days with the snapshot version too.
[Nexus 9 Original Android Development] horst0815:
you won't regret it.

What I don't understand: the snapshot works flawlessly, the nightlys don't... So why's the snapshot working?
[Nexus 9 Original Android Development] dragonballz2k:
This is right snaphot right "cm-12.1-20150901-SNAPSHOT-YOG4PAO237-flounder.zip" there is two different ones just wanted to make sure I had the right one.
[Nexus 9 Original Android Development] FlickFlack:
There is one snapshot of Lolipop 5.0 and one for Lolipop 5.1. The snapshot ""cm-12.1-20150901-SNAPSHOT-YOG4PAO237-flounder.zip"" with "cm-12.1" is the one for Lolipop 5.1, so the newest android build inside.
[Nexus 9 Original Android Development] FlickFlack:
Today I installed cm-12.1-20150901-SNAPSHOT-YOG4PAO237-flounder.zip together with the newest stock firmware LMY48M. The only thing I need to flash too was the vendor-build-prop-fix-signed.zip.

After that everything is running and boot process is fast as usual.
[Nexus 9 Original Android Development] erioho:
Finally I installed CM12.1 today, on my LTE version N9. The mobile connection option was missing, though still can add APN to use the LTE.

BUT BUT BUT! My tablet can't charge!!! (Not because of installing CM12.1, even in stock ROM, it won' charge) Any one experienced this? I use a 3A charger come from my Chromebook, work well with my Sony Z1C and Samsung S3,.

I checked with teh battery usage, it seems the current not entering the device but the status is "Charging". Mostly hardware failure. Share you experience.

9/19 nightly

Just letting you guys know the 9/19 nightly does not boot as well. Like most of you I am on the latest snapshot, witch is working great.
[Nexus 9 Original Android Development] horst0815:
it boots, it just sits at the google logo for 4-5 mins before the actual boot animation plays. like all other nightlys released after the snapshot, which is absolutley fine
[Nexus 9 Original Android Development] mbl1979:
Oh, seems I haven't let it sit quite long enough.
[Nexus 9 Original Android Development] mbl1979:
OK, no kidding like 5 minutes to go from Google screen to boot screen. So yea the nightlies are working.
[Nexus 9 Original Android Development] mattspew:
So are nighties working again? Normal boot up and stable?

I'd like to update my early August version, but the thread is now dominated by slow boot and snapshot discussion and nothing about the conflicted being fixed. Are people even working on the issue? It's getting frustrating.
[Nexus 9 Original Android Development] FlickFlack:
The nightlies are not fixed yet as I know. This fix need to be submitted or further changed

http://review.cyanogenmod.org/#/c/106264/

I suggest that you install latest system images(boot/vendor/system/etc.) than install snapshot, gapps and buildvendorfix and you will have a daily driver. Works perfect for me.
[Nexus 9 Original Android Development] Xelphos:
Quick question. Is it safe to flash CM12 for Nexus 9 WiFi, and TWRP [Flounder] on the Nexus 9 LTE?

I have read a few posts saying it was, but this is my first LTE tablet, and I just want to be 100% confident before I do it. I bought the LTE version because it was cheaper than buying the 16GB WiFi version (Sounds odd, I know.).

Wifi 16GB = $399.99

LTE 32GB = $359.99
[Nexus 9 Original Android Development] 9Lukas5:
You won't brick your device, and its likely that the device boots fine. But I'm not sure if the builds are fully usable on the LTE version, so in the worst case I'd guess you won't be able to use the mobile network, as the drivers for that part are missing in the Wifi only builds.

But that's only a guess, also possible the WiFi builds are fully working or the tablet doesn't even bit and you have to flash a compatible rom^^
