I've searched but I can't find the answer for a VZW Note 3. Can I downgrade from KitKat to JB? The Android OS battery drain is driving me crazy
You can. I used this rom, http://forum.xda-developers.com/showthread.php?t=2787627, still KK based but I have great battery life. Check your SD card. If you are using the SanDisk Ultra card replace it. It cooked my first note abd caused issues, including wicked battery drain, on the replacement.

Did you take the NC4 OTA or did you upgrade via the NC2 leak? If you took the NC4 OTA there is no going back to JB. If you did the NC2 leak then yes you can.

I'm not sure. I installed a rooted stock KK version, then I tried to Odin back to JB and my phone went bonkers. A milIion hours later, I ended up installing the NC4 ROM that was suggested and I'm still testing the battery life. Losing about 10% per hour right now but I'm waiting for it to settle in. I was losing 2% per hour with JB.

When I booted, the Safestrap screen would come up but it was really pixelated. It wouldn't respond when I tried to choose recovery or continue. After trying to install JB with Odin, that failed miserably and I ended up installing the NC4 ROM.

Odin without root? This is possible?
Sent from my Gorgeous S6 Edge Plus
I had the same problem. Arter97 kernel helped me. After root, stock samsung kernel won't go into deep sleep. Even after stock samsung odin flash
Hy guys...
I got rooted my G928F and now i want to go Back to original soft, but when i do that... DeepSleep is not working anymore
Can i do something to resolve this issue without rooting my phone again ?
Best regards and thanks in advance
I dont think there is a way to do that..but why would you do that? U successfully rooted it .. its more nice to have root access
You need to flash the firmware again (you can download from sammobile.com), this will remove your root. I suggest disabling edge feed, edge and edge lighting these two features are know to prevent the phone from dozing (deep sleep)
Hello Costibetter1,
Unfortunately there's a known bug on this phone with deepsleep when Knox is triggered which cannot be resolved easily. Therefore, I advice you to keep using stock, but install a kernel such as Audax that comes with a deepsleep patch.
Hope that my answer to your question was helpful!

Flash custom kernel. Might work.
Flashing custom kernel worked for me. I use SkyHigh kernel v3.0.0.
Hello guys.... thank`s for your Reply`s but they ain`t helping.
I`ve already tryied out this:
1. Flashed Firmware 6.0.1 with Odin (Not Working deep sleep)
2. Recovery flashing Firmware 6.0.1 with SmartSwich (Not working deep sleep)
3. Downloaded PAC firmware and PIT file, selected on Odin NAND Erase and EFS Clear and same result... not working deep sleep
4. I want to go back to original because every custom rom that i used it gives awful score on Antutu, and phone gets laggy sometimes...

i have tried both kernel .
but audax kernel work fine for me :good:
Hi guys, I also face a similar deep sleep issue (Knox was tripped when I bought the phone and the phone is currently not rooted). I'm planning to flash Audax Kernel while being on stock ROM.
I have a few questions before flashing the kernel which hopefully you can help me with a simple Yes or No to the following
The Audax kernel is in .zip format. Hence, I would not be able to flash it via Odin right?
If so, does that mean I will have to first flash a custom recovery and then flash the Audax kernel using it?
After flashing both the custom recovery and the kernel, I will not be able to install OTA updates right?
In addition, will flashing the recovery/kernel wipe my data?
Thank you in advance!

Hello Su_Tweetz,
To flash Audax Kernel you need a custom recovery such as TWRP, that you also can find on the forums and it will not wipe your data (other than cache and dalvik cache). The kernel itself cannot be flashed using Odin, as there's certain modules in the .zip file that need to be flashed as well, otherwise things will not work as intended. OTA updates will not work and therefore I recommend that you install a rom while you're at it, so that you can get said updates by flashing a newer version of the rom.
Hope that answers your questions and happy flashing!

So yesterday I ROOTED the phone using CF Auto root method. I thought I'll use the phone for a bit and see how it works. To my surprise, using CPU Spy app I found that now the phone goes to deep sleep after many months.
However, the next cycle it again didn't go to deep sleep after recharging. Then I used the Package Disabler app to disable all bloat.
Now the phone goes back to deep sleep and works fine. So I'm not gonna flash the kernel yet. Hopefully this will keep working like this. Fingers crossed.

Cpu spy, you can download on playstore, root is not required
Btw, my phone is not rooted (never was) but if i charge it 100% i need to restart my phone to enter deep sleep, otherwise my phone will stay most of the time on 400mhz, doesnt go to deep sleep if i dont restart, i have G928C with latest update PE8, since i got 6.0.1 im with this small issue.

Same here. I noticed mine also doesn't go into deep sleep after charging to 100% (mine is rooted with tripped Knox). So I restart the device after a full charge every day.
Battery life has been good so far now that it sleeps well. Lasts for a full day (>15 hrs) with 3.5-4 hrs SOT.

Hello guys. I have a Galaxy S4 (TouchWiz Lollipop 5.0.1) that is rooted with KingRoot (I replaced KingRoot with SuperSU anyway), has a stock ROM, a custom kernel and TWRP recovery. I did install a custom kernel because I wanted to improve the performance and the battery life, but I noticed that even with tweaking settings a bit in STweaks , my battery life and overall performance hasn't improved. Especially the battery, it drains so fast.
My kernel is an Imperium Kernel (https://forum.xda-developers.com/galaxy-s4/i9505-develop/kernel-imperium-ll-kernel-v1-0-t3058867). I chose this one because it works well with stock ROM.
What I'm thinking is that I've been updating my phone from KitKat 4.2 but I've never wiped cache or factory reset anything, so maybe some "incompatibility" is causing this bad performance and battery drain?
If I wanted to factory reset my phone now from the TRWP recovery (without touching /system of course), would it cause incompatibility with the stock ROM and the custom kernel? And would it somehow help me improve my phone performance and battery duration?
Don't think so.
A custom ROM would make a true difference to general performance, but battery life may vary.
I found this ROM made by the same dev who made the kernel.
If I flash this, will it erase my current kernel?

It's still TouchWiz. TouchWiz is not known for its performance, that's why many people choose AOSP or Lineage.
@Pwnycorn , could u help me?
First of all sorry that I asked a question here but I had to do this as I wasn't answered in my thread.
I flashed a custom Kernel and now I've lost my network signals. Although my phone detects sim card as I can see contacts but I'm unable to make call? When I installed stock rom nothing happened. I tried restoring boot.img with no luck as every time my phone doesn't even boot after restoring boot.img.

No sorry I mean if I flash a JB stock kernel to my KK rom, would it cause problems?
Sorry but I've got no idea about kernels.

Of course it would! They are for different Android versions; it's like trying to put a cube into a triangle shaped hole.
Because of the horrible battery life I'm getting, I want to try stock… but rooted with Magisk. Is there a pre-rooted current stock ROM out there?

Check the battery capacity with Accubattery first, maybe you just have a bad battery and you gotta change it.
