You have to flash the vendor blobs right after the kernel while still in recovery, nothing else.

Make full nandroid backup before, or at least custom backup of "boot" of your currently running OS, that you can easily restore for the case that the new kernel doesn't boot.

[Galaxy Tab 2 10.1" Android Development] Android-Andi:
Result from my p3110:

Clean flashed SlimKat. No Gapps. Using test2 kernel for slim.

WiFi turned on. Setup alarmclock to wake me up in the morning.

Turned off my screen and checked after 7 hours sleep: still 100%.
[Galaxy Tab 2 10.1" Android Development] tetakpatak:
OK, I have tested now after SlimKat also A-A test 2 kernel for Omni and Cyanogenmod 11 (latest official nightlies as of today) on my P5110

So all three kernels are booting perfectly fine and all major functions were working!

Now all the guys who have faced battery drain problems: it's your turn!

[MENTION=5153662]Android-Andi[/MENTION] LOL, test 2 kernel for Omni shows up in "About tablet" as SlimKat kernel. Is it just the text of kernel description overseen by you or did I flash the wrong kernel? (I think I haven't mistaken the version)

tetakpatalked from P5110
[Galaxy Tab 2 10.1" Android Development] Android-Andi:
Wow thx a lot [MENTION=5051515]tetakpatak[/MENTION] :)

It is normal that you see "SlimKat" for the kernel on all the ROMs because I used it as base.

But I worked my commits to have them nice looking and also working on the other kernel sources ;)

My base were a 500.000 lines diff *lol* using [MENTION=5117218]tuxafgmur[/MENTION] s commit to solve the drain, but I shrinked it down to the main changes.

So thx to him also :)
[Galaxy Tab 2 10.1" Android Development] MikeyMan:
Will there be a single update in the future? Don't really understand what those vendor blogs are.

Any idea if and when the fixes will be incorporated in cm?
[Galaxy Tab 2 10.1" Android Development] Android-Andi:
Only if I got enough feedback. Else I won't commit anything to cm... Missing p51xx feedback...

If my changes got commited (later) I close this thread.

The vendor-blobs needed by the kernel to make the kernel work correctly.

[Galaxy Tab 2 10.1" Android Development] tetakpatak:
Great, mate! It is [MENTION=5153662]Android-Andi[/MENTION]'s kernel.

Look, please try his new CM11 test nightly build with implemented no-drain kernel from here:

http://xdaforums.com/showthread.php?p=54310557

And please follow the flashing instruction in that post.

Just create before that a full nandroid backup of your system which you could restore if necessary.

Please report in the same thread after the test if all is fine. Our greatest and most active dev doesn't even own a P51xx tab, so he can't test himself...

Thanks for all the feedback.

Now lets make it happen official:

Please check CM 11, OmniRom and SlimKat thread for latest unofficial builds.

I need to confirm my patches working without issues to get the changes merged :)

My part done, now it is up to You (all user) if we can get the changes merged!

Same thing here. Flashed the kernel over CM11 nightly, no drain. 5+ hors of screen time and battery graph completely flat on standby.

Thank you guys so much. It was driving me insane.
[Galaxy Tab 2 10.1" Android Development] jcsy:
Thing is its slightly higher drain, about -30 ma during standby

I think when without drains it was a nice -9 to -15 range

Are we going to introduce governors and over clock?

[MENTION=2478576]Tsjoklat[/MENTION] updated the vendor-blob installer-script.

He found out, that it is not setting the proper permissions on some of the files (for CM11) and patched it.

Please together, test the "test2" kernel on CM 11 and OmniRom again (SlimKat also, but drain not exist, so not a must to test).

Flash the updated blobs directly after that.

I am not sure, how long i'll stay here and support the Tab 2 - maybe i'll drop support soon as i am really k.o. from supporting to much devices and roms.

It would be great, if we can fix this problem together before i'll leave - else all the hours and days i spend in this commits have been for the a$$.

For Tab 2 7.0 i got damn less feedback, but i need it also to confirm my patches working and not breaking - so press your thumbs there will be some user who are willing to test and giveing proper feedback.

[Galaxy Tab 2 10.1" Android Development] Android-Andi:
i have seen on sammobile.com samsung released more 4.2.2 updates until July! That means: our kernel-source meight be outdated.

We can fix some bugs like poor battery life and maybe some more, but only with your help - the XDA-Community!

These bugs are caused by OS kernel which is not up-to-date with stock ROM’s and Samsung is refusing to update it. Our previous requests have been ignored by them, and the point is that Samsung have to update it, they are just forced by law and licensing terms of Linux, however they just don’t want to do this because of some unknown reason.

I think that the only way to get an updated source code is to… Show the power of our community and spam them with request messages. That’s the only way to fix Tab 2 bugs wich are still present.

S3 mini and Ace 2 community have done this before with a great success, so we can do this too! It only took 2 or 3 days until Samsung updated the S3 mini kernel source!

It’s a nasty way, but it’s the only thing we can do as a community, because previous requests have been ignored.

I'd be very pleased if you want to help. It’s easy, just send them the message provided below:

Dalvik has to live for the many, many, many legacy devices out there. They can't just make it disappear.

Yep, not crazy about ART being "obligatory" now either, benchmarks so far don't show the promised bump in speed google has been talking about, and apps take more space due to the pre-compilation.

Burn-in (uneven wear to be more accurate) will still happen in any AMOLED device. the technology has improved so it should not appear until quite some time down the road, at least it's supposed to have improved.

I have a strange problem where the sim drops out from time to time. I get a message that tells me to reboot. Problem is, when this happens in my pocket or if the phone is not in use, it can take some time before I see it and reboot the phone.

I have seen that someone uses Tasker for this purpose.

Can someone tell me how to set up Tasker to reboot the phone when %SIMSTATE changes? Do I need root for that?
[Galaxy S 4 Q&A, Help & Troubleshooting] vpwrf:
Tasker's reboot action probably needs root. The problem with the %SIMSTATE variable is that it isn't dynamic (monitored) so you can't set it so it triggers on variable value. You can set it so it checks it every 2 minutes instead and reboot if the SIM is not available.

Time: From 00:00 every 2m Till 23:59

Enter: RebootNoSIM (170)

I see that Imperium has reboot option where I can chose , reboot, fast reboot, recovery or download. Could that menu interfere with the reboot command? How can I get Tasker to reboot the phone as instructed?

You must have TWRP recovery on your phone, the preferred and most reliable version is 2.6.3.3, then you must put that guru reset file on your internal storage and flash it from within TWRP recovery like you would do with a custom rom, select install in TWRP and then select the guru reset file, swipe to install and follow the instructions.
