[ONE Q&A, Help & Troubleshooting] ashishsaggu:
Hi, i recently flashed the Cos 13 ZNH0EAS260M rom my opo TWRP 3.0.2.0

Now my phone is charging very slowly. It shows 15hrs for full charge even after having 30% battery.. And the battery goes down when i am charging and watching a video.. I also tried charging with the phone switch and still no luck.. Its charging very slow..

So is this a software problem? Or a hardware issue?

Edit: i checked the amperes i am getting while charging with the oneplus one charger using the oneplus one cable. Its not going more than 250amps.. Can anybody help me with this issue??
[ONE Q&A, Help & Troubleshooting] ilukz:
Hi, have you found a solution? I have the same problem
[ONE Q&A, Help & Troubleshooting] koktiba:
have u tried reflashing it with stock rom
[ONE Q&A, Help & Troubleshooting] SanOne+1:
Solu:

1. Try Changing Carger cable ( I am using xiaomi USB cable) or charger

2. If you are ok with Root - switch to boeffla kernel - apply charging twicks from boeffla config app.

i tried several methods to install custom recovery on my xperia L. I failed all the time. my phone is rooted and please help me how to install custom recovery . :(:(:(:(:(
[Sony Xperia L] n78 shadow:
1_First of all you should be on the latest version of the stock ROM .17

2_Root your xperia l (use the link)

Now there are two methods:

With PC :

install recovery using this tool

Without PC (works with CM) :

Use this app

[Sony Xperia L] singhkaran7121:
I tried the method including pc on my xperia l as It has locked bootloader... It didn't work... I downloaded the file.. And then connected my phone with debugging on... And installed but didn't work.. Do I need to switch off the phone and then connect it?
[Sony Xperia L] n78 shadow:
Are you sure you have SU mode (root your phone via SU in the linked I gave).

If it didn't work try the app.
[Sony Xperia L] singhkaran7121:
I rooted my xperia l with kingroot and it is rooted I guess..
[Sony Xperia L] n78 shadow:
Try the SU as I tild and make sure that you're on the latest firmware 17
[Sony Xperia L] singhkaran7121:
Okay I will do it and then try again
[Sony Xperia L] n78 shadow:
If it didn't work try the other method (without computer)
[Sony Xperia L] Aenadon:
But method without recovery does not work on stock with locked bootloader
[Sony Xperia L] n78 shadow:
You mean without PC.

No he has unlocked bootloader cause he want to install custom rom
[Sony Xperia L] Aenadon:
Oh right I mean without PC :silly:

He said he tried to unlock, but in the post above he says that it has locked bootloader...
[Sony Xperia L] n78 shadow:
Wooo I didn't notice it ok.

Sorry I thought he has UNLOCKED BOOTLOADER casue he wants to install custom rom.

Thanks bro anyway

What is OscarKernel?

OscarKernel is a modified kernel based off of the stock kernel. It only runs on TouchWiz 6.0.1 ROMs for the Verizon Note 4. This kernel is built from stock CPD1 source. I keep my kernel very stable and simple, no flash and glitz, just a reliable and fast experience with some modern enhancements.

What toolchain do you use?

Christopher83's optimized Cortex-A15 Linaro 4.9 toolchain.

You can find it here

What features are in OscarKernel?

Rebased on latest VZW MM source
USB Fast Charge
BFQ/FIOPS/ZEN IO Schedulers
MSM Hotplug
Undervolting support
Overclocked to 2.8 GHz
Yankactive/Nightmare/Zzmoove
Minor bugfixes

Where can I find the source/changelog?

My github repo is here

Who contributed to this project?

Numerous other developers who I will add here as soon as possible. Should you feel you belong here, PM me and I'll happily add you to the OP.

How do I flash this kernel?

Simply copy the zip to your device or MicroSD, and install using TWRP.

Downloads:

v1.3 Download

Additional information:

Q: My phone won't remember my Wifi passwords, what's wrong?

A: You need to modify /system/build.prop to change this line:

ro.secure_storage=true

to:

ro.secure_storage=false

Have a bug report to make?

I need to see the kernel log. To get a copy of your kernel log, follow these instructions using ADB:

adb shell
su
cat /proc/kmsg > /sdcard/log.txt

Other questions?

Post them in the thread. Please do not clutter this thread with easily-answered questions or feature suggestions. This my personal kernel that I am sharing.
[Verizon Galaxy Note 4 Android Development] mexigga:
Looks interesting. Will give it a go! thanks [MENTION=766721]ryanbg[/MENTION]
[Verizon Galaxy Note 4 Android Development] SlothlyDX:
Thank you for this. I like the exceed kernel but wanted more gov options. This is perfect. I will test and let you know how it goes. I also found that intelliactivex is a great gov but I'm excited to try these
[Verizon Galaxy Note 4 Android Development] EdrickMG:
I have viper4anfroid and dolby mods, do you believe use this kernel could cause a problem? I'm asking because in xceed was harmful run both
[Verizon Galaxy Note 4 Android Development] howellcp:
Anyone having issues with the download?
[Verizon Galaxy Note 4 Android Development] SlothlyDX:
Nope works great
[Verizon Galaxy Note 4 Android Development] thetrangdam:
I'm using Jasmine 4.3 but I was stuck in a bootloop (Galaxy Note 4 screen) after flashing the kernel.

So I had to flash MultiSystem kernel again ^^
[Verizon Galaxy Note 4 Android Development] EdrickMG:
Same here in kyubi port
[Verizon Galaxy Note 4 Android Development] SlothlyDX:
Did you guys wipe cache and dalvik after flashing the kernel? I'm in paulpizz with no issues.
[Verizon Galaxy Note 4 Android Development] android-incredible:
No issues with paulpizz either.
[Verizon Galaxy Note 4 Android Development] thetrangdam:
Yes, I did wipe cache and dalvik after flasing though. :p

Maybe I will try it again.

Currently I'm on stock rooted & emotion, I wonder if this kernel help me get more battery life...
[Verizon Galaxy Note 4 Android Development] ryanbg:

I'm on BPA1 BL
[Verizon Galaxy Note 4 Android Development] bobloblaw1:
Kernel is working well so far on PaulPizz with BPA1 firmware.

The only issue I'm having is unvervolting won't apply and throws the error: /res/synapse/actions//ovuv[1]: can't create /sys/kernel/krait_uv_info/krait_UV/: No such file or directory.

I can't manually create these directories either. Is this due to the kernel currently being set to SELinux enforcing?

Thanks again! It's working well, I'd just like to see if I could get it to run a touch cooler.
[Verizon Galaxy Note 4 Android Development] cleopete:
I had the problem with Jasmine on Xceed. I wonder if it isn't the radio? I didn't want to lose BPA1 which was a huge performance improvement over 5.0.1, so I never loaded the BOK3 baseband. (which is also 5.1.1, so that is kind of a dumb reason I guess, never mind).
[Verizon Galaxy Note 4 Android Development] mexigga:
Just installed...no issues on PaulPizz rom.

Governor by default is interactive...not sure which is best just yet.

Am open to suggestions!
[Verizon Galaxy Note 4 Android Development] joemill:
Hello [MENTION=766721]ryanbg[/MENTION]. I'm so happy to see more developer's working on our n910v! I've been using Xceed kernel since build 2 for a while now on my n910v dev edition running jasmine rom 4.3.

Xceed Build 2 had the brightness bug (because I'm still on the 4.4 kit kat bootloader) [MENTION=3637908]kairi_zeroblade[/MENTION] fixed that in his build 3 vzw. The only issue I saw was a delay in opening the camera in any app and switching between the front and rear camera.

Just tried to install your Oscar kernel build .1 and got stuck on the samsung note 4 boot screen (says kernel in yellow font in top left) then reboots to same screen after about 10 seconds repeatedly.

I'm guessing this is because I'm still on the 4.4 bootloader. Is there a way to update that to the most current 5.1 one and keep root and the bootloader unlocked?
[Verizon Galaxy Note 4 Android Development] ssb13:
Still on yankactive? I'm trying yankactive with fiops today too.
[Verizon Galaxy Note 4 Android Development] EdrickMG:
I would say that combination is the best to me, I ain't a gammer but battery been the best since I got note 4
[Verizon Galaxy Note 4 Android Development] ssb13:
I've gone back to Nightmare...I feel like it drains less when not in use.

Nightmare/FIOPS/MSM Hotplug
[Verizon Galaxy Note 4 Android Development] PhillyD77:
Can you put up links for these [emoji13]
[Verizon Galaxy Note 4 Android Development] shadeau:
They're already in the kernel. Just use something like Kernel Adiutor to select the governor, hotplug, and I/O scheduler
[Verizon Galaxy Note 4 Android Development] EdrickMG:
Never been out off yankactive I'll give a try nightmare do you belive battery is even better with it?
[Verizon Galaxy Note 4 Android Development] ssb13:
I feel like when I don't use my phone, nightmare drains less. I don't see a lot of difference otherwise. I do enjoy the fluidity of nightmare.
[Verizon Galaxy Note 4 Android Development] EdrickMG:
i tried emotion kernel and battery is not even close to Oscar's Kernel, yeah there are some things like wakeup locks but battery on yankactive its the best of the best never will be out of it awesome job [MENTION=766721]ryanbg[/MENTION]
[Verizon Galaxy Note 4 Android Development] Martygz516:
I have this kernel and now I cannot change my apn settings to use my tmobile sim in my unlocked note 4 from verizon. Also I cannot make calls or receive them.
[Verizon Galaxy Note 4 Android Development] Matthenson20:
What ROM are you on, 5.1 or 6.0.1? How did you flash
[Verizon Galaxy Note 4 Android Development] Martygz516:
I have 5.1.1 and I ended up flashing the kernel off my SD card which I had to transfer it onto via another phone. Here is how it turned out.

1. Kept getting stuck in a bootloop

2. Removed SD card and installed the kernel and beta super su on card while in another phone

3. Removed SD card from other phone. Added it back to note 4

4. Flashed kernel and super su

5. Went to add Apn settings and notice none available. See screenshot

I ended up downloading a APN settings app from the play store just to add data. Now i cannot make or receive phone call. I had to also download the Advanced Signal Status app from the play store in order to actually make a call. These two options are temporary fixes however and still not the best.

Im going to change the rom soon but i have not got to it yet.
[Verizon Galaxy Note 4 Android Development] nh97103:
My battery life is *vastly* improved from the stock kernel (on yankactive and fiops) and all I can say is thank you so much.

[Verizon Galaxy Note 4 Android Development] fz798:
[MENTION=766721]ryanbg[/MENTION], love this kernel. I impulsively/impetuously flashed the new modem and kernel [MENTION=5868929]hsbadr[/MENTION] posted in the JasmineROM thread, and while the modem thus far seems fine, it didn't take long at all to remember why Oscar is so good. I'm back on r13 and happy again. This is neither an overt nor a thinly veiled ETA.... just wondering if you are still maintaining this kernel?

Thanks again for such a great kernel.
[Verizon Galaxy Note 4 Android Development] ryanbg:
I've upgraded to a Nexus 6P, but I still check this thread and will make occasional updates as I see fit. Currently waiting on latest stock source to be released from Samsung.
[Verizon Galaxy Note 4 Android Development] EdrickMG:
Looking forward I only have a request... emotion and some other kernel are compatible with dolby atmos but... Oscar's not I would try to get a log to see what's floating

Hello ryanbg. Got a question. Do you think this would work on chevyrhoads Full Note 7 port?
[Verizon Galaxy Note 4 Android Development] shadeau:
If you search that thread for "Oscar" you'll find several people that have gotten it to work on the port. You can read their experiences and judge for yourself if you want to try it.

Slight problem with the latest paulpizz rom, this makes my phone think the sd card is corrupted.

Since using this, my battery was at 50% then after opening Snapchat it went to 15% and then 1% within 2 minutes. :eek:
[Verizon Galaxy Note 4 Android Development] Sizzlechest:
After flashing this kernel, my screen brightness was pinned to the highest level regardless of the setting. I flasshed back the Multikernel and it's working again.

I have no issues with that.
[Verizon Galaxy Note 4 Android Development] joemill:

[Verizon Galaxy Note 4 Android Development] ssb13:
I installed this kernel this morning, made no modifications, charged up phone and let it sit untouched for a couple of hours while I worked. Zero issues. Battery seems amazing so far. My phone was completely up to date via OTAs prior to converting it to DE recently so it has latest firmware, radios, and boot loader. Using PaulPizz and couldn't be happier. I was loving xceed as well, so no doubt I am enjoying oscar as well. :)
[Verizon Galaxy Note 4 Android Development] mexigga:
I have to agree with you on everything. I converted my N4 and used the Kyubi N5 port, which was fine but [MENTION=4999212]PaulPizz[/MENTION] you've hit it out of the park with your rom. This kernel is amazing! Thanks [MENTION=766721]ryanbg[/MENTION]

Thanks.
[Verizon Galaxy Note 4 Android Development] ryanbg:
Hey guys, been busy the past week. I'm updating the kernel today with a couple fixes, including the 4.4 bootloader/screen brightness issue.

EDIT: See OP for v0.2, 4.4 bootloader/brightness issue should be resolved.

EDIT 2: I'm looking into the Kyubi/Ketan issues, but I think this has to do with those being ports and might need custom kernels. This kernel is for stock 5.1.1 or close to. Anyone wanna try flashing Xceed on either of those ROMs and see if the issue remains?
[Verizon Galaxy Note 4 Android Development] SlothlyDX:
the latest update is much better. My phone is much smoother and much cooler. Thanks
[Verizon Galaxy Note 4 Android Development] joemill:
My phone will still not boot with Oscar kernel .2[emoji22] shows boot screen for about 10 seconds then reboots and repeats the process.

Works good with Xceed build 3 vzw

[Verizon Galaxy Note 4 Android Development] Asiangamers:
Bamm...pretty good battery life kernel using a yankactive governor nothing expect more than this[emoji2] [emoji2] [emoji2]
[Verizon Galaxy Note 4 Android Development] ryanbg:
I'll investigate and figure it out
[Verizon Galaxy Note 4 Android Development] thetrangdam:
I've been using your kernel on PaulPizz rom these 3 days and it's working great with nice battery life (Although my battery isn't so good I think...) Thanks ryan.

By the way, I have a side question I hope someone can help me answer it.

Is it enough just to change CPU governor in Kernel Adiutor app? Or do I have to do some other tweaks to make it work? It would help me a bit with performance & battery life if I just changed the CPU governor am I right?
[Verizon Galaxy Note 4 Android Development] ryanbg:
Yeah, CPU governor is pretty much all you need to do. Sometimes I'll play around with the IO scheduler, but other than that, everything is already pretty optimal. Undervolting isn't really necessary on this device, otherwise really my goal is to have only stable code in this kernel. I'm hoping PBA1 source is released soon, otherwise I'll send Samsung a GPL request so we can get the latest kernel source.
[Verizon Galaxy Note 4 Android Development] thetrangdam:
Thank you ryan.

That's good to know, I don't really want to dive that deep into several kernel stats & modifications.

Since my battery isn't really good compared to others' on xda, even though I bought another one, I'm having a good time with your kernel. I can't really test SOT because I'm at work all day so I didn't use it much. I now have 65% battery left after 30 hours system up with around 2 hours SOT. :)

Thanks again man.
[Verizon Galaxy Note 4 Android Development] Zues532:
I flashed Xceed last night in an attempt to get data working on Dr. Ketans. It booted fine, but no data. When I attempt to enable data, it asks me to "insert SIM card". Reboot doesn't fix.

Reflashed Verizon Datafix (Multisystem Kernel), and all is ok.

I'm happy to try something else if you have any suggestions.
[Verizon Galaxy Note 4 Android Development] ryanbg:
I was doing some experimenting yesterday. Upon installing PaulPizz and immediately installing my kernel before reboot, I was greeted with a black screen. If I installed the ROM first, allowed it to boot and finished setup, then reboot and install kernel, I didn't have any issues. Not sure what's going on yet but will continue to investigate.
[Verizon Galaxy Note 4 Android Development] Zues532:
I just DL'd the latest version of PaulPizz (5/06/16), and will mess around with that later this evening after work. I really like these note 5 ports, and will gladly switch back when I have working data and full control over the kernel.
[Verizon Galaxy Note 4 Android Development] KingVekxin:
So does Oscar kernel play well with zerolemon batteries
[Verizon Galaxy Note 4 Android Development] mexigga:
Works great but does not track battery stats properly.
[Verizon Galaxy Note 4 Android Development] Matthenson20:
Love this kernel, any recommendations for an app to be changing settings?
[Verizon Galaxy Note 4 Android Development] ryanbg:
I use Kernel Auditor
[Verizon Galaxy Note 4 Android Development] Matthenson20:
I was trying, but I noticed when I try to change min and max values they don't stick, is there a reeason? Sorry its been a while since I've rooted and things have advanced a little since my last go
[Verizon Galaxy Note 4 Android Development] ryanbg:
The governor and mpdecision should handle all that for optimal values. Don't worry about that. The only things I'd recommend changing would be IO scheduler to BFQ or FIOPS, and maybe the governor to yankactive.
[Verizon Galaxy Note 4 Android Development] Deluriane:
Just a noob question. Which is better BFQ or FIOPS?
[Verizon Galaxy Note 4 Android Development] EdrickMG:
[MENTION=766721]ryanbg[/MENTION] just Yo let you know sammobile update full firmware in his website, it could be awesome Oscar kernel for marshmallows

Nice choice with yankactive too.. my first time using it, very nice.

Edit- Well found a possible bug ... seems that when you disable wifi and then turn it back on, it's forgotten all of your wifi passwords now.
[Verizon Galaxy Note 4 Android Development] ryanbg:
That will happen with any non-stock kernel. The fix is simple. In /system/build.prop, change ro.securestorage.support=true to ro.securestorage.support=false. Glad you're enjoying the kernel.
[Verizon Galaxy Note 4 Android Development] Matthenson20:
LOVE THIS! Has anyone had time or know of a place where MM kernel tuning has been written up with a tutorial? Focusing on Low Memory Killer, virtual memory settings, governor settings etc?
[Verizon Galaxy Note 4 Android Development] Android.Ninja:
[MENTION=766721]ryanbg[/MENTION]:

Best damn MM kernel for the note 4 on XDA.

You should have named this "OctaneKernel" because this kernel smokes the competition leaving the rest in the dust!

Smooth, clean, & fastest kernel to date. This should have been the stock kernel. Samsung, you need to be taking notes, cause this is how it's done. ?
[Verizon Galaxy Note 4 Android Development] weaverinva:

What is the kernel signature in about phone so that I can confirm the flash loaded properly?
