Strange....for me it doesnt work. How can i. solve this?
[Nexus 5 Original Android Development] hocruxx:
Okay. What file explorer did you use. I try total comander and nexus media importer it detects my otg. But in es file and astro it didn't detect my otw

Sorry for my bad english
[Nexus 5 Original Android Development] eng.stk:
Root explorer, gave up on ES a long time ago.
[Nexus 5 Original Android Development] slayp00n:
Hi eng not sute if y saw my post earlier but your kernel is not working with the cm12 builds.
[Nexus 5 Original Android Development] BTT8:
Max frequency is 1497 on 620? I've tried setting it back to 2200 but it defaults back. Phone temp is cool so it can't be thermal throttling..
[Nexus 5 Original Android Development] eko_cahyono:
I have tried so many kernel on nexus 5,all of them the battery life is not good. I'm only get SOT 2-3 hours on average usage. But with this code blue kernel, the battery life is AWESOME! i can get SOT 4-5 Hours... Thank you dev for this great kernel.
[Nexus 5 Original Android Development] 1haumann1:
Which file must be edited for dt2w?

keep calm and have a Nexus :D
[Nexus 5 Original Android Development] -sheldor-:
I got more than 5 hours of SOT yesterday, great! thank you for that wonderful kernel :good:
[Nexus 5 Original Android Development] onesolo:
You didn't understand...

My Thermal screen on Synapse is not like this one:

I only have Temperature Threshold... nothing more... how do I have the rest of the options??
[Nexus 5 Original Android Development] hellsgod:
The screen you're showing is intellithermal, which isn't built in anymore. Thats why your screen looks different.

hells
[Nexus 5 Original Android Development] eng.stk:
If it goes back, you are being throttled. Or ayou have other thing messing with your freqs.

Frequencys are min-max stock and stick fine.
[Nexus 5 Original Android Development] eng.stk:
These are the defauts (off):

[Nexus 5 Original Android Development] Traxex_:
I keep getting "device not supported" when opening Synapse.

I'm on LRX21O with Code_Blue 620, permissive, root and Ukm 3.5 installed.

Any suggestions?

Nobody acknowledged my bug report: kernel is not working with CM12 Build.

once we had a little argument here ... thank u for hard work anyway ;) going to give a shot . i can now download
[Nexus 5 Original Android Development] marf28101995:
If you could provide more information we would help

1st cm12 is unnoficial

2st its likely 90 aosp and 10 caf

And these 10% could be causing the problem

3rd working perfectly on aosp Roms
[Nexus 5 Original Android Development] :
A bug report has more information than just "it's not working". You didn't include any logs, problem descriptions or even explain how you did the installation.

Secondly as said above, the CM12 builds right now are unofficial. There isn't much point working on a kernel until something more permanent comes up.
[Nexus 5 Original Android Development] afraaa:
Flashed latest stable 620 . white color is good . contrast is good . and it is smooth . and smooth factor is most important in 5
[Nexus 5 Original Android Development] slayp00n:
The first time i wrote it i detailed the issues, this was the 4th attempt to get acknowledgement.

Flashing CB breaks System UI. The navigation button only has back, and the lock screen is unavailable (swipe). If you apply a pin / pattern lock-screen then system ui will just constantly crash.
[Nexus 5 Original Android Development] :
Let's wait and see if those same issues are there when the official CM12 builds or nightlies start. We can't expect eng.stk to cater for personal builds as well as official roms. Otherwise him and other kernel devs would need to support tens or even hundreds of individual builds out there :)
[Nexus 5 Original Android Development] Berget:
is it just me who getting lagg sometimes?, like when oppening snapchat or messenger...
[Nexus 5 Original Android Development] bknightt:
Just flashed this on L, gonna post my thoughts on a day or two, I've flashed stock boot.img, and system.img to remove any remaining kernel fragments from previous kernels and followed the instructions provided by OP. Everything went smooth, thanks!
[Nexus 5 Original Android Development] marf28101995:
Not happening here mate
[Nexus 5 Original Android Development] C0deFire:
Great work on the kernel! Really happy by flashing it :) keep up the good work!
[Nexus 5 Original Android Development] ColdFire InOx:
I can't seem to edit the force_fast_charge script. I delete the 0 and write a 1 but after I save the 0 is automatically there again.
[Nexus 5 Original Android Development] limzm:
[MENTION=3873953]eng.stk[/MENTION] is it possible to prevent/disable the "touch_boost failed to send" error message from PowerHAL for every touch? I am unsure if this actually cause battery drain upon usage and I am skeptical about it.
[Nexus 5 Original Android Development] hellsgod:
Rename or delete /system/lib/hw/power.hammerhead.so reboot your phone and you're fine ;)

hells
[Nexus 5 Original Android Development] limzm:
Wow thank you [MENTION=647113]hellsgod[/MENTION]!

Now I hope to see some improvement in battery from all the touches. [emoji106]
[Nexus 5 Original Android Development] eng.stk:
That is just an info message because I don't use mpdecision. Doesn't influence battery whatsoever.

You need to edit it with a root capable editor, like the one from Root Explorer for instance.

Or echo from a terminal as root
[Nexus 5 Original Android Development] timvdhoorn:
Please let us know if you see some improvement!
[Nexus 5 Original Android Development] vtec_:
Performance is noticeably more snappy than stock and Franco kernel. You just stopped me going back to KitKat, keen to see how the battery performs!
[Nexus 5 Original Android Development] timvdhoorn:
Which app do you recommend for changing kernel settings and color profiles?
[Nexus 5 Original Android Development] aslam_:
kernel tweaker or trickster mod
[Nexus 5 Original Android Development] timvdhoorn:
And for colorprofiles? Because i don't like the default of this kernel
[Nexus 5 Original Android Development] limzm:
One cycle now and result seems to be similar.

I will test for another cycle and see what happens.
[Nexus 5 Original Android Development] stark_br:
I use FKU to control the kernel and it has built in color profiles.
[Nexus 5 Original Android Development] eng.stk:
Code_Blue r646

All right crew!

Just pushed a new release, go get it!

Merged some CM12 and CAF updates, storage patches, blu_active upstream tweaks to better performance (battery is +/- the same).

You can now use SuperSU 2.27, most root apps work without going permissive. Kudos to Chainfire :victory:

Kernel is now compatible with Lollipop stock, Latest AOSP and CM12 (this could change if CM updates between releases)

Get involved, test, play, donate, help, contribute.

You keep the spirit alive!
[Nexus 5 Original Android Development] Flamehell:
Best kernel out there.....tnx a lot man!!!!:o
[Nexus 5 Original Android Development] DarkFantasy6:
I love your Kernel!! Code Blue was running buttery smooth and battery friendly on Mahdi Rom and on stock android 5 it is still the best kernel. It makes lollipop really really fluid and smooth and the battery life is good! :) thumps up [MENTION=3873953]eng.stk[/MENTION]
[Nexus 5 Original Android Development] thucoisao:
with the new one i can connect to the internet and using taptalk, facebook, ... but not for any kind of web browsing even a local ip address. back to 620 is fine now.
[Nexus 5 Original Android Development] Tylog:
This is for sure no kernel isuses.
[Nexus 5 Original Android Development] thucoisao:
Sure, i knew it. Strange but true.
[Nexus 5 Original Android Development] Tylog:
Yes. Do you use AddAway `?
[Nexus 5 Original Android Development] thucoisao:
No, i'm not using any ad blocking app. Just dont know how if happend on my end.
[Nexus 5 Original Android Development] eko_cahyono:
Just fine here... Can you use your phone to call? Maybe its radio related
[Nexus 5 Original Android Development] eng.stk:
Why no logs? But for sure not kernel related, probably a reboot would fixed it anyway :cool:
[Nexus 5 Original Android Development] thucoisao:
yeah, i think it's not kernel related so no log. thanks dev.

P/S: rebooted a few times.

How To Retain SuperSU Root Permission with Code Blue Kernel on custom Lollipop ROMs

How To Retain SuperSU Root Permission with Code Blue Kernel on custom Lollipop ROMs

Not sure how many here have flashed Code Blue kernel on N5X ROM (ver.5.4), but recently I discovered that even though I had Superuser in my Settings menu, my Rooted apps (MyBackup Root, Root Explorer, Wakelock Detector) were not working after I flashed a custom kernel like Code Blue kernel.

After digging through various forum threads, I have managed to make my rooted apps work again on a custom kernel like Code Blue.

Hopefully some of you may find this how to guide helpful.

Pre-requisite

Download the following files to your Nexus 5:-

Permissive Kernel Zip

- https://www.androidfilehost.com/?fid=95747613655048458

Code Blue Kernel for Lollipop

- http://xdaforums.com/google-nexus-5/orig-development/kernel-t2697951

Latest SuperSU by Chainfire (at the time of this post it is [BETA][2014.11.20] SuperSU v2.27)

- http://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

- Direct download link: http://download.chainfire.eu/630/SuperSU/BETA-SuperSU-v2.27.zip

Step 1: Reboot to TWRP Custom Recovery

1. Shut off the phone

2. Press and hold Volume Down + Power Button

3. Use Volume down to toggle to Recovery Mode and confirm selection using the Power Button

Step 2: Flash the Permissive Kernel

1. Click on Install button in TWRP Custom Recovery

2. Select the Permissive Kernel Zip file which is N5_+LPX13D_PermissiveKernel.zip

3. Swipe to Confirm Flash

4. Click on the Home button only!

Important Note:

Do Not

click Reboot System yet!!!

Step 3: Flash the Code Blue Kernel

1. Click on Install button in TWRP Custom Recovery

2. Select the Code Blue Kernel Zip file (at the time of this post is Code_Blue_r620-L_hammerhead.zip)

3. Swipe to Confirm Flash

4. Click on the Home button only!

Important Note:

Do Not

click Reboot System yet!!!

Step 4: Flash the latest SuperSU

1. Click on Install button in TWRP Custom Recovery

2. Select the SuperSU Zip file (at the time of this post is BETA-SuperSU-v2.27.zip)

3. Swipe to Confirm Flash

4. Now click on Reboot System button and wait for the phone to reboot.

Once the phone boots up, you should have SuperSU appear under the Settings menu.

Try to reinstall your rooted apps again just to make sure they get fresh root permission from SuperSU.

hi... i cannot find DT2Wake on trickster...its usually in the "Specific" Tab right? and also i cannot find it in the fauxClock. It is usally in the n"Miscellanious".

if i want to set timer for Dt2wake with ES explorer, what value should i add in sys/android_touch/wake_timeout? is the value in here in second?
[Nexus 5 Original Android Development] dEris:
Finally. With latest SuperSU and r646, UKM survives reboot. Been using stock and this was annoying having to manually run script in terminal on every reboot. You devs are amazing.

You can't find it here on XDA...

with a little setting on trickser mod, i managed to get 6 hour 30 min SOT (still 14% battery left) :D
[Nexus 5 Original Android Development] R3Lax1:
Underclock? Could easily get up to 6 h of screen time without it on KitKat.
[Nexus 5 Original Android Development] aslam_:
im talking about Lollipop. i dont even care what it can get on KitKat.
[Nexus 5 Original Android Development] topgeardave:
Kernel settings make marginal difference mate, I recommend using stock. Biggest gains come from turning off your wifi and mobile data when you're not using it. Keep the brightness low as possible, turn off location and auto sync. Greenify your social media apps or uninstall them, use bbs to find your app wakelocks and Greenify them.
[Nexus 5 Original Android Development] eng.stk:
You don't need all of that to get root working in that ROM or any other.

Kernel support root fine, don't need any permissive junk, my kernel is full .img that replaces all the kernel image.

It's SuperSU 2.27 that makes the difference, all the apps work nicely now!
[Nexus 5 Original Android Development] aslam_:
min 300000

max 1497

gpu 320

uv -50

location and auto sync off

and using greenify to prevent any wakelock
[Nexus 5 Original Android Development] dEris:
Most likely he turned on battery saver the entire time then turned it off to take this screen shot.
[Nexus 5 Original Android Development] R3Lax1:
In my experience, the battery saver isn't that conservative.

Viper4Android, it is the one that is stopping me from using this kernel for now
[Nexus 5 Original Android Development] thereal_bigjake:
It works fine on this kernel but you have to set the kernel to permissive which I use a script to do so.

Hi guys, I don't know whether this issue has been asked or not, or maybe even a part of the governor. I did set my maximum cpu freq to 14xx, but somehow it always return to 22xx.. And also the CPU stats in kernel tweaker also show cpu usage in 22xx freq

Anyone know how to get volume gain on this kernel on lollipop?
[Nexus 5 Original Android Development] eng.stk:
Freqs stick just fine, you must be having something interfere with your settings.

You need to tick show notification on boot, and it will autoset on reboot
[Nexus 5 Original Android Development] GtrCraft:
Doesn't work but I changed it in synapse and now it works
[Nexus 5 Original Android Development] aquavalanche:
Well.. Personally I have no idea as well. Only cpu freq that ramps up by itself while the GPU stays still. Here's the screenshot. Do u recommend other kernel tweaker that may work better?
[Nexus 5 Original Android Development] t1.8matt:
Synapse or Trickster MOD. I'm using Synapse at the moment. You
[Nexus 5 Original Android Development] eng.stk:
I don't use any other tools, just trickstermod and/or UKM and there is no issues.

Terminal echos works fine also so...

You will always have 2.3 use because on reboot that freq is used alot (for obvious reasons) and you set UC after a while only.
[Nexus 5 Original Android Development] onesolo:
Does this kernel supports f2fs ??
[Nexus 5 Original Android Development] eng.stk:
Maybe will :angel:

https://github.com/engstk/hammerhead-5.0/commit/eade3f725c8db7609a94c803977e4c83aa364b74

Any F2FS ROM so we can test?
[Nexus 5 Original Android Development] Spectrum75:
[MENTION=3873953]eng.stk[/MENTION]

Regarding F2FS, check Kener's G+ for OptiPop Rom and some more info about F2FS on Lollipop ;)
[Nexus 5 Original Android Development] aquavalanche:
I just changed to trickster. I'm going to give it a shot. I'll report to u later. Thanks mate for such a solid kernel
[Nexus 5 Original Android Development] R3Lax1:
The stock 5.0 factory image has built in support for f2fs itself, you can just reformat in twrp and restore a backup, though an f2fs kernel with a proper ramdisk is required.
[Nexus 5 Original Android Development] eng.stk:
I like clean zips, no hacks ;)

So far F2FS on Data & Cache is working nicely, F2FS-all (System+Data+Cache) should work too, didn't find a ROM to test, maybe later.

[MENTION=3873953]eng.stk[/MENTION]

Yes you are correct. I have tried your latest Lollipop kernel and flashed SuperSU 2.27 and I have root now. Your kernel is awesome! Keep up the good work.

[Nexus 5 Original Android Development] topgeardave:
Hey [MENTION=3873953]eng.stk[/MENTION], how is testing coming along for audio offloading? :)
[Nexus 5 Original Android Development] Fluidification:
Does this kernel install by modifying the ramdisk on the fly? The reason I ask is because I'm trying to use cm12 and if they patch something in their kernel, I would like the changes to still work on the modified kernel lol.
[Nexus 5 Original Android Development] slayp00n:
Hi Eng, just wanted to update latest cm build again breaks your kernel.
[Nexus 5 Original Android Development] topgeardave:
Which one? I'm rocking 25/11/2014 cm12 and it's working fine here with no issues :)
[Nexus 5 Original Android Development] killer86th:
I got the opposite problem, I didn't touch the max cpu freq, but after using this a while it would be cap at 14xx instead of 22xx, and it will stay that way until I notice and change it. Is it the work of thermal throttle? because I use my phone for 3D gaming a lot, if so, it should jump back to the default max freq after the temperature cool down I guessed? I tried to set max with Kernel Tweaker then Trickster, but got same result.

Anyone had the same experience? Only 2 apps that had root access (I investigate there as I think only root access app can adjust max freq cap) are Titan Backup free & Kernel Tweaker (or Trickster)
[Nexus 5 Original Android Development] pianistaPL:
OptiPop ;) http://uber.oceighty.co/HAMMERHEAD/OPTIPOP/
[Nexus 5 Original Android Development] frontalot:
I've had the same problem and still haven't found a solution.
[Nexus 5 Original Android Development] killer86th:
You also gaming/using heavy apps?
[Nexus 5 Original Android Development] topgeardave:
Flash ukm 3.5 and install synapse from play store. Then bump up thermal throttle from 70 degrees to 88 degrees. Throttling should hardly become an issue unless your game is that demanding that it requires the cpu to max out at all times.
[Nexus 5 Original Android Development] -iNSiGhT-:
There's an option for temp_throttle in Kernel Tweaker (Kernel tab), so he can start trying with this app he already uses.
[Nexus 5 Original Android Development] corwin42:
Same here. Just noticed in trickster that max was 14xx. Never touched the setting.

Gesendet von meinem Nexus 5 mit Tapatalk
[Nexus 5 Original Android Development] aquavalanche:
Mime now is fine with trickster mod. Looks like it was kernel tweaker problem in my case.

Well, in yours, have u ever flash other kernel before?
[Nexus 5 Original Android Development] killer86th:
Already did that with both Kernel Tweaker & Trickster (up to 80 degree), still got the same result. Anyway, it's just my assumption that thermal throttle is the reason (because I play 3D game a lot), still need further testing though.

Nope, I flashed Code_Blue straight from stock, Code_Blue FTW :cowboy:
[Nexus 5 Original Android Development] GtrCraft:
I got 1497 cpu max too, I use synapse and my temp is 36C
[Nexus 5 Original Android Development] nickporwal:
Same here but its hardly a problem as whenever i boot my mobile i adjust the cpu frequency using synapse and it just sticks. Maybe the problem with synapse or ukm. Doesn't bother much.
[Nexus 5 Original Android Development] eng.stk:
Throttle works fine: if it goes over the threshold it goes down to 1.4GHz, than on cool down it goes to default 2.3GHz (or other freq you select).

Either you system is on load and creates heat or you have something else messing with freqs.

Check my Antutu run to simulate cpu temps raise.

EDIT: keep in mind one thing: for instance let's say your max is 2.3GHz. During throttle it goes to 1.4GHz.

During throttle you go to UKM and see it's 1.4GHZ: don't press the V on top (ukm detects freq has changed), because this way you will be setting max temp to 1.4 even after throttled ended!

Don't know if in other apps this can happen to.

I test on Euroskank builds, there's no significant changes in kernel should be working fine.

So far so good... will debut on next release for sure.
[Nexus 5 Original Android Development] estate:
sorry but, which is for cm12..? the one in test section with number r1196?

Thanks
[Nexus 5 Original Android Development] GtrCraft:
The weird thing is, I am far from the throlling temperature (36C) and it still happens sometimes
[Nexus 5 Original Android Development] GeorgeTF:
on kernel tweaker is called temp_threshold right?

can i change it to 80 degrees (?) because i have the same problem with freq

going to 14xx istead of 22xx.
[Nexus 5 Original Android Development] topgeardave:
R646 in stable section mate
