I9500 Kernel (Light Weight Kernel 20.4) Issues - Galaxy S 4 Q&A, Help & Troubleshooting

There's only one kernel for i9500 CM, and after flashing LWK 20.4 my wifi stopped working and I've just dirty flashed CM12.1 on my phone again.
Well, since I can't post on development forum: is there anyone that can help me with this?
The original reason I've dabbled with kernels is the abhorrent battery life I was getting out of my box. Like, 6-10 hours with little to no usage!
When I've first installed gearCM about 5 months ago, battery life was tolerable. Not as good as stock firmware, but good enough to last the day. I've installed OTA updates every few weeks and after the latest such event (~2 weeks ago?) my battery just started to drain.
I've re-installed another rom, Resurrection Remix 5.5.8, which still drained battery. Now I'm on official CM 12.1 latest nightly. Google services crashes every now and then. I haven't really gotten a chance to test battery life, but I'm pessimistic.
What can I do about a good and functioning kernel with a stable ROM? (no TW please)
CM and CM-based roms I like most, but if LWK isn't going to work on them, what other ROM would you recommend?

Try PAC ROM 5.1.1

Hi,
Try GearMod kernel and let me know.

Pa/omni/cm11

puzzled for choices in custom roms .
which is the best and the most stable at the moment ?
i am on Omni for the moment because its officially supported and latest updates are released as nightlies .
please help
Didn't try PA, although it has unique features you may like.
I was on Omni until yesterday's nightly messed up everything, then switched back to CM11 based Probam, which is also great.
Try yourself and then decide.

I'm using t0lte CM11 myself, http://forum.xda-developers.com/showthread.php?t=2530116. It's very good. The battery life is great 2+ days with a lot of messaging, e-mail-ing and about 1-2 hrs of talk.

[I9505] CM12 nightlies vs official stock ROM for Lollipop?

Hi guys,
Now that the stock ROM has been around for a week, I was curious if someone made the switch from CM12 or any other custom lollipop ROM to stock and would like to share their experience?
I, for instance, switched from CM11 (4.4.4) to stock and found the battery drain worse than in kitkat. Customization is also a clear drawback on stock lollipop since Xposed modules are not ported yet. Would like to know if any custom ROM matches the stability of stock and goes beyond it's features :what:
I don't usually use GPE or CM roms but I'm really really liking JFLTE-GPE 5.0.1 http://forum.xda-developers.com/showthread.php?t=2557353.
I've using it for a week and been having great battery. Last night I just installed Xposed alpha for Lollipop with GravityBox[LP} with no issues.
http://forum.xda-developers.com/showthread.php?t=3034811
http://repo.xposed.info/module/com.ceco.lollipop.gravitybox
Using the same GPE rom as posted above for about 3 months. No problems.
It also has good battery life. If you let the phone idle, it will last you around 2 weeks
That's what the battery stats reported this morning.
I used CM11 for a long time, (since it was released till now), and I have to say, I'm a fan of being technical updated. ATM I'm using the Stock 5.0.1 Samsung Lollipop (of course, with removed Bloatware), and I'm afraid. I like the Samsung UI für the Stock, thats a little reason for me to use the Stock-ROMs. I don't have any Battery issues or find it worse than CM11. And even if, I've got my JBL Charge and Charge 2 to charge my phone in city. haha.
Well, i like them both but for now, I prefer Stock 5.0.1 (and can't wait for 5.0.2/5.1.0). Maybe i change back to CM12 (Antares/Alucard) when they made a 5.1.0 Update (forum.xda-developers.com/galaxy-s4/i9505-orig-develop/rom-cyanogenmod-12-t2943934).
I too used CM11 for a while on my i9505 and I loved the customization freedom. But I was pretty miserable about the battery life and overheating issues. Also, the stock camera was MUCH MUCH better than the one on CM 11 or even the Google Cam.
I am now back to stock with 5.0.1 and the battery life and camera have revived. But I equally miss the customization, so was wondering if anyone would recommend a custom ROM over stock.
I just went through an ordeal all for Viper4Android. Tried various kernel work arounds on stock 5.0.1 to get the V4A driver to install (no luck). Flashed to CM 12.1 and thought I was set only to find that cellular service (no sim card) didn't work. Flashed back to CM 11 and had the same issue. Then tried a ROM call Triforce and bricked my phone. Ended up doing a factory reset/wipe back to Lollipop 5.0.1 and now everything works again, but I'm not happy with the sound quality I'm getting now vs what I had with V4A under Kitkat. Wish I'd have never upgraded. V4A was wonderful. Anyway, CM 12.1 seemed to be pretty good for the short time I had it.
Part of me wants to try CM again but I don't want to go through all the problems.
Viper4Android needs a permissive kernel to work. If SELinux status is Enforcing then it won't work. Generally custom kernels have it set to permissive.

You are correct. The stock Lollipop kernel would never change to permissive no matter what the SELinux setting was. Very frustrating. Only solution that I could find was kernel replacement via a different ROM. Didn't quite work out though due to the cellular network loss.
Edit: back on topic, I made the switch but only out of necessity and not desire.

Galaxy S4 i9505 Stable&Battery Friendly ROM

Hello guys! I have decided to ask for your help as I ran into a bump. I have been flashing a lot of ROMs lately but I can't find something that suits me. I am looking for a rom that is near to bugless, has a great battery life and can be customized a bit. I don't really like TW roms because of the way they look. I am currently running Resurrection Remix v5.6.2 but I encounter some bugs, so it's not for me.
Could you suggest me something good, please? Either KitKat, Lollipop or Marshmallow (if there is one).
Or, if it's not really that battery friendly, one that charges pretty fast. I am tired of waiting 3 hours for my battery to be full
As far as battery life goes, I think Touchwhiz is the best. It can be customized with Xposed.
In terms of charging speed, Lollipop seems to be faster than Marshmallow.
Try the GPE roms. One is untouched, meaning it has no root or modifications.
Hello, I installed Untouched GPE and have been using it for the last 2 days. It's a stable and snappy rom, only has some few minor bugs. But the charging is soooo slow, and the battery life isn't too good either. Any suggestions on a stable ROM that's not touchwiz based and performs well, with good battery life or charges very fast?
Hello guys, I have one more request from you: please name all the ROMs that you know for S4 that are bugless and very stable, regardless of the android version: kitkat, lollipop, marshmallow etc. Thanks!

A bugless rom does not exist. Stock or custom all have some bugs. Almost all roms out there are stable.
And the battery life is just bad on the s4. Not much you can do about that.
One important thing you should know about roms is that, if a rom works perfectly fine for me, for you it might not work as good.
For me, every rom worked perfectly fine, while for other users, the same rom, wasn't stable.

Which rom has the best battery backup? Plz help!

I bought my Zuk Z1 phone one month ago and I was very upset with the battery backup of the phone for before buying I went through many videos reviews boasting the battery backup of the phone. After using the official CM 13 from the cynogenmod website I was still not satisfied. I then moved to custom rom and I am quite happy with the battery backup. I have tried Dirty Unicorn, MrColdbird Rom and right now I'm using Teamsek rom the latest one. Which Rom has the best battery backup for our device for I want to stick to only one rom less my battery will get affected. Plz help me to decide. Thank you

You have tried 4 roms and cannot decide for your own which rom gives the best battery life for your purpose???
Less apps, data connection and sensor usage the more the battery will survive [emoji106] But I suggest try radioactive kernel with official cm13 nightly and deactivate as much payload as you can. Otherwise nuclear rom ist also a good choice, the mentioned kernel is already built in. Google Apps drain the device, so be patient which are you using. Knowledge of kernel settings ist your key to get the most battery life out of your device for YOUR purpose. You must try and measure, it's time-consuming...

I have been using MIUI latest its super stable it gives me aroud 6 hours SOT sometimes more than that.
Battery backup, screen on time depends on your usage. Heavy users like me don't get much SOT on this phone. I am on lineage OS 14.1 14th Feb build and I play clash of clans frequently, throughout the day and I Hardly get 4Hours or 4.5 hrs of SoT for around span of 11-12hrs. And also I keep data connection ON for 24x7. If you are a moderate user and turn off data connection after use you'll be fine on any rom I guess. If you want latest stable build with latest security patch, then definitely go for lineage OS. It's most stable ROM out there and stand by time is just awesome. Everyone has like and dislikes for each and every ROM, maybe you should flash some more ROMs and decide for yourself.

Going Back to Lollipop - Any Recommendations ?

Hey guys,
after trying many marshmallow and nougat roms and kernal combinations I think I may go back to a Lollipop rom. I just have not found anything that gives me a well rounded experience (gps, bluetooth and decent battery life are the deal breakers for me). Yes I know I could go back to stock and root and debloat but I just don't like touchwiz.
What rom/kernal combinations would you all recommend for Lollipop ? Would this be a wise choice security wise ?
Also, I would even go as far back to KitKat if there weren't the security issues. KitKat had some of the most stable roms I've ever used, especially on my old note 2 lol I miss using that thing sometimes.
Any help would be much appreciated !
Thanks!
I guess no recommendations ?
Anyway, I ended up trying Temasek Unofficial 12.1 again, Team Exodus's rom and ulimately settling for the last Official CM12 Nightly (20161016). I tried all 3 of these with the latest Idle Kernal
Temasek seem's to work for a lot of people but I always end up with a lot of issues with it especially in battery.
The Team Exodus rom was very promising and I wish they had of not stopped working on it. Bluetooth, GPS etc. working flawlessly. But battery life just wasn't good.
CM12 has been great. I have not had a hitch with it and everything seems to be working and I'm getting excellent battery life.
The most stable ROM for the phone will be a stock ROM. You can easily root a stock ROM to remove bloatware too.

Touchwiz Based Lollipop ROMs:
1)Aryamod Lollipop ROM
