Hi guys, not sure if other had the same issue with me, but I hope you can help. I have the 9200 variant (HK) and sometimes I get huge battery drain from the stock email app (samsung one) and the app does not synchronise (both with wifi or 4g). I have there only exchange emails (corporate ones). If you restart or if you kill the email storage process, it works fine (you receive all the emails instantly and the drain stops). I had the same issues with the kernel by Gundal, so I believe it has nothing to do with the kernel itself. Any suggestion how to fix that or what the issue could be?
[Galaxy Note5 Original Android Development] UpInTheAir:
Do you have SkyHigh kernel? If so, please post a screenshot of your Synapse INFO page. In any case, please refrain from spamming non related issue in a Development thread. There is Q&A for this ;)
[Galaxy Note5 Original Android Development] Kyrillos:
Point taken. Please see attached the requested info. If you can't assist, i will start a separate topic. Thanks in advance.
[Galaxy Note5 Original Android Development] UpInTheAir:
Tech support. ... "clear app data" - "factory reset" - "update your firmware".....

I've heard OKA may not work with the current source. But no user has replied to my request in v2.7 release post.

Anyway, going to drop support for devices with little or no user feedback, or "development inconsistencies" (as arter97 puts it).
[Galaxy Note5 Original Android Development] Zanr Zij:
I'm not on computer right now so I need a bit more time to test and report back. I really like your kernel options/customizable: OC + UC on both, inceaseable charging currents, audio tweaks... Of course I don't want to be in case: drop support.

Anyway thank you for your great devs for community
[Galaxy Note5 Original Android Development] Kyrillos:
Thanks for the Tech support :)

Give us some time for the feedback. Tried the sammobile site to download the new firmware, but it's down for some reason. I've also read from another topic. What they did, they recompose the firmware in order not to update the bootloader. Anyway, whatever the case, I will try to download the OKA as it is in order to test last version and give you the feedback.
[Galaxy Note5 Original Android Development] UpInTheAir:
Just remember that the current custom kernels may not work with that bootloader and you could be stuck on stock until Samsung source release. I do have an idea, may or may not work, but for users ALREADY flashed the OKA bootloader. I had a similar experience with my Note Edge, found a solution and just about the next day was ye source update! ! Typical. ..
[Galaxy Note5 Original Android Development] cornelito:
Are you going to stop developing for N9208? Please don't.

Using v2.7 on sva rom... Amazing.. Thanks [MENTION=7095711]upin[/MENTION]
[Galaxy Note5 Original Android Development] pelpa87:
hi! first of all i wanna thank you for the work!

but..I have the N920C Variant with 3.10.93 SkyHigh_TW_V2.6 Kernel...and i'm having 2 issues.

1) systemUI restarts itself every now and then. it doesn't FC it just restart itself and lock the pone.

2) Also some times, it appears that system is not responding and pone reboots itself.....every it happens every 2 days or so..

Is there any configuration in Synapse i'm not seeing? i left all default configs...
[Galaxy Note5 Original Android Development] cornelito:
Great ! You're our best developer.
[Galaxy Note5 Original Android Development] UpInTheAir:
1. Read the change-log

like you're supposed to ;) Clear Synapse data and flash new v2.7 kernel ;)

2. Don't UV or UC so much

Yeah, you guys/gals do report on successful boot etc. Thanks.

Ha. Ha. Because I'm the only one currently supporting N9208. The best of one lol

Does this kernel work with gear vr?
[Galaxy Note5 Original Android Development] bynam:
hi

Thank you for your best kernel.

I want to know which version have Best Battery Life Without use Synapse ?

on MY SM-N920CD

THANKS
[Galaxy Note5 Original Android Development] UpInTheAir:
OP

Anything other than latest release is unsupported unless used for troubleshooting.
[Galaxy Note5 Original Android Development] Kyrillos:
UpInTheAir, can you please provide me with .tar file of your kernel for 9200. I installed the OKA firmware, but can't boot into twrp :( Will install the kernel via Odin. Tried your kernel with a system.img which was extracted from the OKA firmware (without updating the boot loader) and it was working. Thanks in advance.
[Galaxy Note5 Original Android Development] UpInTheAir:
You had been warned multiple times in various threads of the "risk" N9200 OKA firmware posed with source compatibility etc. ...............

I do not post tar-balls or support it if a working TWRP or Philz is available. Maybe you need to look at that.

Here is a "one off", SM-N9200-kernel-SkyHigh_TW_v2.7.1"-[15-12-11].tar.md5 test version of the latest N9200_HK source merged into my source. This may or may not boot or have undesired results. I just don't have your device to fully test. All I know is that it compiles and also boots on my device with limited testing.

You know which [button] to hit................... ;)
[Galaxy Note5 Original Android Development] Kyrillos:
I was warned but than you wanted somebody to test. I thought i could always use my backup. Anyway, at least the phone is working properly :)
[Galaxy Note5 Original Android Development] UpInTheAir:
I only requested from user that had already updated. .. you can search and will confirm it.

So how is the kernel?
[Galaxy Note5 Original Android Development] -viperboy-:
For those that don't want to use Odin, check out Chainfire's FlashFire app. I'm sure OP will still recommend you use Odin, but just an alternative for those that know what they're doing.

[MENTION=573708]bill340[/MENTION]

I'm getting the N920I next week. Can you tell me which version of the Kernel you flashed?

There are 2 in the OP:

1. For the 920 C - L

2. For the 920 T.

TIA
[Galaxy Note5 Original Android Development] UpInTheAir:
Probably works OK. I've never tested it and only recommend what I've tested to be reliable.

in terminal:

su
cat /sys/kernel/debug/asv_group

Also, you can find some info in your last_kmsg

My output reads different from other kernels I've had, giving group 0.............. but if I read it correctly, giving differing group to for each frequency. (could be wrong on that).

I enabled asv margin test in build and same result.

I need to cross-reference with the source at some point, but no time to worry about it now.

EDIT: just checked a little further - this is better :

Sreenshot attached !!

su
cat /sys/kernel/debug/asv_summary

Not yet until I have GPU Frequency Scaling control. I don't have time for that right now or in the near future.

REBOOTS DURING CALL

Just testing ATM, don't know what's going on in log either.

Appears random duration -

WIFI enabled 5:30 min OK

Datat enabled ~1:00 min reboot

Data enabled ~4:00 min reboot

Data enabled 5:30 OK

WIFI - Hangouts 10:00 OK

(No WIFI or Data)

wipe cache & dalvik cache reboot

(option in Synapse > FS ) ~20:34 mins OK (as [MENTION=573708]bill340[/MENTION] suggested)

Will try same with Data/WIFI enabled

Will edit THIS post on completion of tests.
[Galaxy Note5 Original Android Development] bigxie:
Thanks [MENTION=3511708]UpInTheAir[/MENTION], I was able to grab my ASV numbers with that command

root@nobleltetmo:/ # cat /sys/kernel/debug/asv_summary
cat /sys/kernel/debug/asv_summary
big:6, LITTLE:6, INT:6, MIF:6, G3D:8, ISP:6

For any other users interested, I've been running ~25mV undervolt across the board with no stability issues. I don't think I need (or want) to push it much further as I'm already experiencing extremely great battery life on this device.

Wiping cache+dalvik right now to test if it helps with the call reboots.
[Galaxy Note5 Original Android Development] mocsab:
Thanks for the work you have done so far - I am curiuos if there is a guide for reccomended settings in Synapse or should I assume that the default settings are the ones you suggest for everyday use? (that is probably a dumb question, but I figured best to be sure)

is there a source that provideds guidelines on doing different settings?
[Galaxy Note5 Original Android Development] UpInTheAir:
I will add asv_summary to display in Synapse INFO section on next build

Post #3 I have have BATTERY and PERFORMANCE section: that is for later on. I only just got the device and no time over the next 5 weeks for development. Trying to get a few things sorted and added before leaving,

Many tweaks are just generic and can be found by searching. Just don't tweak too much and a little at a time. I would suggest not to enable Synapse to apply settings on boot (until you have stable settings). If you aren't sure = don't touch
[Galaxy Note5 Original Android Development] lightdelegate:
Same in here.

Reboot and reboot until I've flashed a stock back again. ..

N920C
[Galaxy Note5 Original Android Development] UpInTheAir:
Not really interested in stock, but did you try as was suggested ?
[Galaxy Note5 Original Android Development] schellemann:
I flashed the SkyHigh Kernel on top of the Noble Kernel on my SM-N920I (Singapore stock rom with no other modifications than Noble Kernel).

No random reboots any more but from time to time reboots during calls.

Disabled Knox with Synapse but still some reboots on calls.

Wiped cache & dalvik-cache with synapse.

No reboots during calls so far with everything on (data & wifi). Made 10 test calls to my 2nd phone and 5 to my fixed landline. All calls between 5 and 10 minutes without any problems. OEM unlock still enabled.

Gonna test it a bit more the next hours. Thanks for all your effort to give us a working rooted toy. Great Job.
[Galaxy Note5 Original Android Development] wish2:
what about private mode ?? is it working for u ???
[Galaxy Note5 Original Android Development] lightdelegate:
Sorry but I've passed all over the posts...

Didn't see anything. ..

Did i missed something ?
[Galaxy Note5 Original Android Development] schellemann:
[MENTION=6799726]wish2[/MENTION]

Nope. Cant even activate it... but for the moment I can live with this. As long as I can do calls without problems...
[Galaxy Note5 Original Android Development] UpInTheAir:
I just wonder if it's OK after reboot or will require wipe cache & dalvik-cache each time (Synapse > FS tab) ? I only assume we need to wipe after each flash.

I can't test it right now as the wife is out with her phone and won't appreciate tying up the connection...............
[Galaxy Note5 Original Android Development] schellemann:
Ok... gonna try this now. Gimme a few minutes for a quick check

---------- Post added at 03:19 PM ---------- Previous post was at 03:01 PM ----------

I shut down the phone and restarted it. After that I did a 10+ minutes test call with my wife without any problems. Email pulls and Whatsapp messages during the call on wifi. It looks like its working even after the reboot. Private mode still not working.

If you need any screenshots or logs let me know and I will try my best to provide you with whatever you need.
[Galaxy Note5 Original Android Development] UpInTheAir:
It's fine for the moment thanks. Got my hands full testing some cool stuff :)

From memory, I think private mode needs to be set up after root otherwise you need to factory reset. I aslo think there is an Xposed module to help, but you will need to deodex your ROM.
[Galaxy Note5 Original Android Development] schellemann:
Ah ok... gonna try it on the next flashing session to set private mode after root. For the moment I am happy with the working and rooted phone. Don't wanna touch anything without a good reason. Thanks for your great work again and keep it on. Looking forward to see your upcoming "cool stuff"

[Galaxy Note5 Original Android Development] mocsab:
Thank you - frankly, with minor exeptions setting kernel settings is way over my head so I usually don't touch anyhting. I have done some UV and some OC on some kernels - but only after reading and getting a better understanding of what is ok to mess with and what whould be left alone. I will do more research -

thanks again

About private mode

Hi bro ,

Is there any chance to fix private mode??
[Galaxy Note5 Original Android Development] schellemann:
Tested, working and no reboots on call. Did a few 10+ minutes test calls with my wife without any problems. But my wife was asking me if I'm getting crazy now because I never called her so many times within a day ;). Thanks for making my wife happy and thanks for your great work...
[Galaxy Note5 Original Android Development] Kyrillos:
Kernel is great!
[Galaxy Note5 Original Android Development] UpInTheAir:
I suppose you have network connectivity?

Just hope all remains well after this next N920S/K/L source merge.
[Galaxy Note5 Original Android Development] Kyrillos:
No issues with network

---------- Post added at 09:22 AM ---------- Previous post was at 09:18 AM ----------

Man I've downloaded your file. It says binary is invalid. :(
[Galaxy Note5 Original Android Development] UpInTheAir:
You just said the kernel was "great".... I can only assume you are taking about SkyHigh because this isn't stock thread. Same for network.....

Try rename to .tar (remove .md5)
[Galaxy Note5 Original Android Development] Kyrillos:
I was talking about SkyHigh. I had it for a week on OJ9 and for limited time had it on a OKA system.img with OJ9 boot loader. Everything was great with the kernel. I only had one an issue with the stock email app, but I am sure this has nothing to do with the kernel itself.

I renamed the file, but it stucks at "NAND Write Start!!" in Odin and would not proceed further. :(
[Galaxy Note5 Original Android Development] UpInTheAir:
I assume you've unlocked via your cron app and enabled OEM unlock in device settings first. If yes, then reflash your stock firmware. I can't help fire the moment, in the middle of a merge.
[Galaxy Note5 Original Android Development] Kyrillos:
Anyway, I used my backup and now I am back to OJ9 with your 2.7 kernel. Will wait till OKA will be propery supported :) Thanks for the support!

[Galaxy Note5 Original Android Development] bala_gamer:
Just tried to undervolt the cores, I remember synapse having global uv settings when I was using s4, not sure. Am I missing the setting some where?
[Galaxy Note5 Original Android Development] Chord_Hugo87:
I think its up to the Dev of the kernel...O remember that option also.
[Galaxy Note5 Original Android Development] UpInTheAir:
I could probably implement that, but since each frequency step is individually "binned", it's better to just have finer control over individual frequency voltage than global.

I might make it optional though, never know.

I am having High battery drain on v2.7 on Android OS.

Had the same issue with v2.6 but not with v2.5

I tried installing this on a fresh stock ROM installed through ODIN and even then it is not going into Deep Sleep.

Am i missing something?
[Galaxy Note5 Original Android Development] UpInTheAir:
I just don't have it on my SM-N920C device with firmware stated in release post.

You haven't posted your firmware version or device model etc as per thread requirements top of Post #3. All screenshot of your Synapse INFO section would be helpful to those with your device model.

I'm currently waiting on feedback from a N920T user to revert a commit to hopefully find why v2.6/2.7 do not connect to his Cellspot. There aren't many source commits in v2.6.
[Galaxy Note5 Original Android Development] aclan:
Hey dude, i'm a N9200 user and been busy these day, i will test your latest kernel as soon as I get some spare time(maybe tomorrow, I will post the result. ) , so keep it on, pls:)
[Galaxy Note5 Original Android Development] cornelito:
Exactly the same observation. Android OS drains my baterry on 2.6 and 2.7 version like never before. Have not had this on 2.5 though.

N9208 with OK2 Stock Firmware heavy debloated, Greenified etc.

Not a rant, just an observation.

Other than that great piece of work. I love your Kernel dude !
[Galaxy Note5 Original Android Development] anmolkakkar:
My Bad.

I am using N920C Dual Sim and is currently running the following build number: LMY47X.N920CXXU2AOK7, rooted and partially debloated.

I am not using Synapse at all. Using just the kernel stock settings set by you.

Yeah man, just an observation from my end too, to help the developer. :)

Great work dev! :good:
[Galaxy Note5 Original Android Development] schellemann:
Installed 2.7 yesterday on my 920I. A few "system is not responding" errors/reboots right after the first boot but no other problems since. Battery life is amazing and anything is smooth and fast. All audio stuff works fine. No lags or freezes so far. Stock ROM (just a few root apps and Nova launcher) with AOH6 Bootloader/PDA and AOH2 Baseband. Thanks for all your hard work.
[Galaxy Note5 Original Android Development] UpInTheAir:
Thanks for your feedback.

I bet you didn't force close and wipe Synapse data in device settings/applications. ... before flash. I would wipe dalvik-cache and cache after those errors.
[Galaxy Note5 Original Android Development] aclan:
I have the same issue(Can not boot into twrp nor Philz ) after I fully wipe my N9200 and clean flash the N9200ZHU2AOKA(with Re-Partition checked), and finally searched this thread and guided me to #778.

So I tried to download your SM-N9200-kernel-SkyHigh_TW_v2.7.1"-[15-12-11].tar.md5 test version, and checked the MD5, but Odin stop me when I tried to flash the file:

<OSM> MD5 hash value is invalid

<OSM> SM-N9200-kernel-SkyHigh_TW_v2.7.1--[15-12-11].tar.md5 is invalid.

So would u pls re-upload the attachment? and I will try again:crying:

[Galaxy Note5 Original Android Development] UpInTheAir:
I've shut down for the night. I try if I have time tomorrow :) But I'm getting closer to next release, and waiting on feedback from a N920T user. After that I will compile > upload > release. So maybe then ;)

[Galaxy Note5 Original Android Development] aclan:
Thx dude;)
[Galaxy Note5 Original Android Development] schellemann:
Oh I did. And I wiped cache and dalvik cache after the first error. Gonna try it again now and will report in 30 mins.

---------- Post added at 11:35 PM ---------- Previous post was at 11:00 PM ----------

Re-flashed 2.7 on my 920I to see if I can reproduce the errors but "unfortunately :)" the phone works like a charm. Does drinking beer while flashing affects the functionality of a kernel?

[Galaxy Note5 Original Android Development] Kyrillos:
Cool. One question, is there any reason why the new kernel is fro CWM and not twrp? I suppose i still can't use it with the new OKA firmware, right?
[Galaxy Note5 Original Android Development] UpInTheAir:
CWM (away from its official meaning) is more or less now a generic term for a custom recovery flashable zip. I'll remove the reference so it doesn't confuse the Noobs ;)

If you'd bothered to look in the DOWNLOADS section, you would see a Odin flashable archive to be used with the stated Odin version.
[Galaxy Note5 Original Android Development] Kyrillos:
I saw the Odin. Just wanted to confirm the cwm part, to avoid unnecessary issues. I will give it a try again with the OKA and let you know whether it works.
[Galaxy Note5 Original Android Development] Zanr Zij:
Excellent job! Now seem all are fine on N920K. I'm testing, report back and do my job now, share to my friends, my community about your thread and your kernel!

To all Korean users: please report back to OP anything you know, you think about his kernel. This help the maintenance and development as long/good as possible!

Thanks both for testing.

So you have root and busybox versions as per OP?. If not, the change-log details what you need to do.
