[Q] What is the fastest stable ROM+kernel+libs? - Nexus 4 Q&A, Help & Troubleshooting

So searching comes up with >1 year old threads and not really answering my question.
I got a used N4 recently for my daughter, and I want it to be as fast and stable as possible. I unlocked, then ADB flashed the currrent Google image and then rooted, made it ART runtime and applied the Z2 Bionic lib zip, applied current Franco kernel. Then I was halted in terms of is that the fastest?
Is that best combination which exists right now?
Is CM11 better?
I didn't really form a concluson of the Z2 Dalvik lib vs ART.

From what I know, this patch is currently faster than ART itself:
http://forum.xda-developers.com/nexus-4/general/4-4-4-4-x-qualcomm-optimized-dalvik-t2546120
Since ART is 'experimental' right now of course it lacks of improvements, but I am sure if Android L is released this October this wouldnt be the case anymore.
Also some Custom Roms like Cyanogenmod has its own optimized bionic libs, sometimes better than the stock ones or any patches. I highly recommend you to try this out, because than you dont have to search and compare no more.
In terms of kernel, I would not recommend you to use franco's kernel on a Custom Rom. Make sure to use any other kernel. This is just my personal experiences with franco's kernel and someone might call me too dumb to use this kernel, but why do I have so much trouble with franco and every other kernel runs fine like matr1x, ak or semaphore? Judge for yourself

Right so I saw the claim that sticking with Dalvic and using the optimised Dalvik lib is faster but I gave up keeping track of it as too much "feels" and "benchmarks aren't representative" conclusion.
Noting to avoid Franco with custom ROMs. The custom one I did was CM and Franco warns to not use it!

the fastest.. whatever im using.
but really, these kinds of threads arent allowed on xda since you are asking us to compare roms. oh, ill clue you in a little, cm isnt even close to the fastest. and no, franco kernel isnt the fastest either.

Best ROM/kernel threads are not allowed on XDA
The best bet is to head over to the development sections and try some out for yourself and see which combination suits you best

[Q] Does a custom Rom come with a Kernel?

Does a custom Rom come with a Kernel?
My specific case :
Nexus 7 32Gb Wifi
Android 4.1.2
Rom : PA 2.54
Kernel : Franco 3.1.10
My plan is to update to PA 2.99Beta6 which is based on Android 4.2.
I'd like to know if I'll also need to flash a new kernel as part of the upgrade process or if the PA 2.99Rom also includes the required kernel.
My guess is that it will be included with the Rom but figured it wouldn't do any harm to ask.
PMSL, how on earth do you think a ROM would actually work otherwise without a kernel.
Sorry but.... #facepalm

My fear was that a Rom might use or expect the stock kernel, cheers for the answer though.
With that in mind, I wonder why Roms don't tend to ship with custom kernels. Franco's seems to be widely preferred to stock.

most roms that are actually developed ship with custom kernels(like cm for example). roms that are just compiled from aosp source that have some mods added usually use the default android kernel(or stock roms with added mods). also, many roms ship with other custom kernels included. anyways, many others prefer trinity kernel

Sorry I may have picked up on your question wrong, but many developers, well in fact most would use custom kernels, some prefer stock, stock kernels are generally very stable but quite limited in what they can do, for example take the pretty amazing Siyah on Galaxy S3 which gives you the ability to dual boot different ROM, s, i had AOSP as my main ROM and a Samsung ROM as my secondary ROM which was great for a while but they novelty wore off for me as I really only used the AOSP ROM, not to mention over clocking , etc, etc, etc.
I use Trinity Seven kernel on the Nexus and i find that the tablet seems to charge faster than with the CM kernel that comes with Liquid Smooth ROM.
Hope that answers some of your questions anyway

PA vs AOKP

Well i'd like to know which are the differences between those roms. I just would like to know if with any of these i'll get same or better battery life than with stock 4.2.2 (which is the one im right now) and if games will run same or better (i don't mind if i have to change kernel, but i'd prefer to not have to do many tweaks).
Also, what would I win coming from stock to any of these apart of the customization (apparel)? Thanks.
Opinions are welcome, I don't want to start a war between which is better, just to know which will fit my requirements. Also, please don't tell me there are 100 threads like this because the system of xda didn't show me any similar threads, and if there are, then sorry.
Not entirely sure on PA, but AOKP (the PUB builds anyway) have some cool optimizations. PA I believe has more customization available than AOKP, and has PIE (some navbar-less thing I believe). I haven't tried PA yet on the N10 so I have no idea really :/
Your welcome to flash one, try it out, and then flash the other though. Probably a better choice to see for yourself which is better.

Wait. is your bootloader is LOCKED or UNLOCKED? You need to be UNLOCKED to flash a ROM. I personally love Task650/Ktoonsez's version of AOKP. The custom kernel they use(Underwear) is pretty fast, but I have recently installed KTManta and it flies. PA is also fantastic, with features unique to PA like PIE and the whole dpi/color thing. I only stopped using it because PA 3.0 had random reboots. They apparently fixed the reboots in yesterday's PA 3.1, so I'm going to flash that tonight and try it. Flash whatever you want to try, just make sure to make backups of everything and you can zip back and forth between ROMs in minutes.

Hey Koopa and thanks. I succesfully unlocked and rooted with wugs toolkit so im just gonna flash PA. Thanks again for the advice! However I'd like if you can explain me that about the backups. If im on PA and I want to go to AOSP (from craig), do I have to restore my backup (I did a backup just after I unlocked and rooted) or I only have to wipe data/cache/dalvik and flash the other rom?

The TWRP backups are images of the tablet at the time of the backup, including data, ROM, and the kernel. You never have to flash the stock backup unless you want to go back to that state(Think of stock as just another ROM, which it is in the end). In your case, you would make a backup of PA, then, with the ROM zip on your tablet, you would factory reset, wipe cache/dalvik, format system(wipe ROM), then flash the ROM/gapps. You technically don't 'need' to do anything when restoring a backup, but I always do just to be safe. A note about the system wipe is that it wipes the ROM currently installed(be it stock, PA, AOKP, CM, etc.) and is HIGHLY RECOMMENDED when changing ROMS or Android base versions(4.2.1 to 4.2.2 for example). If not things can get wonky in regards to the kernel differences and such. I always clean the 4 before switching ROMS and I haven't had an issue. If you make backups on a per-ROM basis, you can wipe and restore the ROM with all your apps and such anytime you want.
I was in a hurry, so if any of that makes no sense content-wise/grammatically, let me know. There are also FAQs that are far better at explaining this than I am, I'll try to find some for you.

No worries, understood it. I see it's pretty different than with my Samsung Galaxy S, but that makes sense since the roms have different base and those have all the same. So if im not wrong, I make a backup of PA, then make all the wipes, and I can go AOSP. That easy?

That is correct.
Both AOKP & PA have a lot customization fun.
Individual features of AOKP
More customize on navigation bar, can even add screen off button.
Ability to add extra apps at Google Now pull up.
Ability to set how many column of Quick Settings.
Individual features of PA
Powerful Hybrid Properties where allow you set different apps different navigation + notification bar & icons color.
Ability to change DPI for every single apps.
Pie support, you can set certain apps full screen (no navigation bar) and the pie will pop-up when you slide from side (depends on where you set at either bottom, left, right or top).
AOKP & PA benefits over stock
Beside above list indivdual settings, both let you set preferable layout UI, either Phone, Phablet (stock look) or Tablet (previous Android tablet look).
Themes support, all CM 10.1 / AOKP themes is compatible with AOKP and PA.
Quick Settings customization, choose preferable toggle.
** Now I am fall in love with PA and use it for my tablet and phone.

Performance wise PA sucks. The input lag on it is completely unbearable to me and greatly hinders fast paced games. As for the features, PA is great. It probably has a couple more features than AOKP but I havent used AOKP in a month so it may have gotten more.

Not sure about the performance since I have it flashed since yesterday, but I saw a video comparison of PA and AOKP on youtube and it looked like AOKP was a lot faster (here is the video http://www.youtube.com/watch?v=VNxdhF-nvec). Is the battery life way worse? And will it be updated to 4.2.2?
Thanks for the comments btw.
I'm also debating. Either Carbon or AOKP.
My main question is:
How is the battery compared to Stock after Flashing?
I'm running AOKP on my S3, I did however try Carbon....but prefer AOKP.
Thanks.
After few days running PA, I am back to AOKP even thought PA features much rich but... not the performance and stability.
PA still need more tunes on it performance and stability.

I also want to try AOKP but there are too many different AOKP roms and I don't know which is the original one. I'm getting frustrated, I was gonna try a "new" one but I saw it has some buggs with games and with volume so I'm not moving untill I know there's a good and official one...

I was looking into AOKP ROMs the other day, and from my understanding there's an official AOKP (somewhere), and 2 AOKP's with PUB optimizations, one being official, and the other being unofficial and posted under general Android development on xda.
I'd recommend the AOKP with PUB. Stable I think is 4.2.1 still, but there are some "slightly" hidden 4.2.2 nightly builds available.

Allright, that stable 4.2.1, which I guess it's the official one, is not gonna be updated to 4.2.2 right? And those 4.2.2. might have some buggs so I'm not sure if wait or try the 4.2.1. I might try it, guess it will still be better than PA in therms of performance, but I love the customization of PA. Thanks.

Unofficial & Official AOKP was far stable than PA, I don't see any big bugs.
They is no bugs of games or sound, don't look too much on bigxie unofficial thread of AOKP 4.2.2, that one was including all user report bugs on Galaxy Nexus, Nexus 4, Nexus 7, and Nexus 10.
I recon only use the 4.2.2 build of AOKP, don't use any 4.2.1 which had hanging/restart issue due to it 4.2.1 main issue.

if you so worry and not trust AOKP, don't use.
Which part I talk on that customize AOKP did by a person that not even have nexus 10. Really funny.
If not dare to dry, don't try.
Also when people talk on specific AOKP ROM, why you not listen, some more message me to others AOKP ROM not mention by me.
I am using and advise you on mrRobinson build, link had given before in official AOKP 4.2.1 thread. mrRobinson did not open a new thread for his modified version which was base on latest 4.2.2 build. He just post there.

My battery life is better on stock. Is that weird?

So I was running stock for a very long time, and I had insane battery life. I usually got 5 and a half hours of screen on time with my usage which mostly included browsing and a bit of youtube-ing and maybe the 30-40 minutes of gaming. I never used it conservatively though, I just didn't need anything else. I had GPS and bluetooth off and I used WiFi only at home (2g, not 3g, when outside).
Anyway, a month ago I flashed PA 3.99 and my battery life has reduced. I only (relatively) get 4 and a half to 5 hours of screen on time. Is this normal? I thought I'll get better battery life with a custom ROM. I'm still running stock kernel BTW.
PA is giving me too many issues including random reboots so I've decided to flash either CM, PSX, Carbon or PACman (help me in deciding from these?). Should I flash a custom kernel too? I'm leaning towards Faux for the battery life but I'm scared it might reduce it!
PS : I just flashed the PA ROM, so I'm still running the stock kernel, right? The thing is, on my older phone, some devs bundled the ROM with a custom kernel. My kernel version says 3.4.0-perf-g04b6fae. Sorry for the noob-ness.
There are just too many factors, the coding, apps installed, kernel, optimization, the user usage pattern, signal quality. It wouldn't surprise me though, but if it work for you stick with it.
Kernel alone doesn't determine the whole picture. I don't use PA, but I don't think it use stock kernel since stock usually ends with "mtv.corp.google.com".
You can check these battery life benchmark for kernels if you want to try, however, I don't go by them: http://forum.xda-developers.com/showthread.php?t=2449982

I did exactly the same, and feel exactly the same... I have the same apps, same usage, and I feel like I have a few hours less with this ROM (and same Kernel). I'm planning to give Franco a try, I think, although according to that benchmark it won't give a great battery life either... Have you already tried anyone?
Just a noob question, I haven't yet completely understood that thing about builds. When I was completely stock I was in JWR66Y. Then I only flashed PA 3.99 RC2 (for that build) and now in settings it says JLS36G. It now means that I have to care that kernels get on well with JLS36G? I thought I would stay in JWR66Y.

there are two versions of 4.3..one is stock (JWR) and one is AOSP (JLS)
the AOSP build is more latest in a way..AOSP build has more speed but has random freezes for 2-3 seconds (should be fixed in most of the roms by now) while stock JWR build is not as speedy as AOSP but doesnt have those random freezes.
And yeah you would now have to flash a JLS kernel rather than JWR..and if you want a kernel with good battery life..try hells core kernel which IMO has the best battery life and performance

after trying multiple different ROMs, kernels, etc.. I found that I wasted a lot of time getting geeked-out over nothing special. Sure, it's fun.. exciting... learning.. some minor features that are cool.. but, I do desire to have those hours of life back. Also, I experienced many more downsides than positives. Battery, lock-ups, random reboots, etc. A rooted stock device has served me very well..

Thanks! I had read about the difference between AOSP and stock, but didn't know/remember that JLS always AOSP. I think I felt this one better than stock. I've already been 4 days with it and I'm really comfortable being able to change dpi individually, custom it and use Pie, too, and stability is just as in stock, I think (I only got restarts in both of them while using Skype :S ). I didn't even worry to try CyanogenMod (in all my previous phones I had used it, always).

That's my concern in trying with new, custom kernels. Right now I'm just fine (although I'd like to have a little better battery life), so I'll keep reading and see if it's worth changing the kernel .
Thank you!

the hassle come with flashing a new rom because you have to do a factory reset..with kernel though its pretty simple just wipe cache/dalvik cache flash kernel then reboot. So just try the kernels you think are interesting and if youre not comfortable with it then flash another one..i know its a hassle with rom but not much with kernel.
P.S you guys should really try hells god kernel. Ive been personally using it for 3 months and the battery life is just amazing
I'm getting good battery life with KitKat.

Yeah, I've already flashed kernels in other phones, but never had this risk of compatibility issues due to different builds.
I've read that JSS kernels in JWR roms cause problems. Is the opposite not true? I mean, right now I have a stock JWR kernel running in a AOSP based ROM (JLS). Could this compatibility problems cause boot issues too? Of course, always with tested kernels. Or I'll always have the opportunity to boot into TWRP and flash a new kernel, until one works?
And one last question. When I look for AK's 4.3 kernel I only read JWR and JSS. Why doesn't it say JLS? Is it the same as JSS, then?
Thanks!
I can vouch for the above statements. I'm liking Hells core kernel. It's fast and has great battery life (as good as stock, maybe even slightly better). FWIW, I'm using Carbon ROM now and it's MUCH better than PA.

Sorry i forgot to mention that JLS and JSS are the same build JLS being the latest one..so there is no difference in JSS or JLS. You can flash a JSS kernel on a JLS build no problem. But if youre build is jwr then your kernel build should also be jwr because yes it causes compatibility issues if you flash a jwr kernel on a jss/jls build or vice versa. In every ROM the stock kernel is matched with its build number. If its a jwr ROM then the stock kernel would also be jwr and vice versa.
Flashing a jwr on a jls/jss rom or a jls/jss kernel on a jwr rom might cause the phone to be in a bootloop (not going past the bootanimation) and even if you get it to boot up the performance would be lacking and it might cause random freezes, graphic glitches and or random reboots.
However there are some roms that are a hybrid which means its a combination of jwr build and jls/jss build. In that case you will flash a jwr kernel only nothing else.

[Q] I just got my S4. What should I do?

I just got my S4 (GT-I9505) from my dad. I'm really excited but I don't know where to start. What should I do first now that I have it? Should I root it first? What is the best Rom and Kernel for this device? Any advice would be much appreciated!
If I were you I will perform a factory reset first This model has many ROMs, you may try each of them and find out your favorite one.:cyclops:

I have i9505 though. I don't think it's compatible?
Once you're rooted and running custom recovery you can multiboot it, (run multiple custom Roms) all information is in this thread: http://forum.xda-developers.com/showthread.php?t=2864469
Alucard's kernel should give you good perfomance.
Or Hulk kernel. With hulk you can overclock the up to 2.1 Ghz. But I feel like Alucard gives you better performance (when running 1.9).
As for the roms, they are all pretty much the same.
I've tried Sabermod CM12.1, Resurrection Remix, AICP 9, FlexOS.
They pretty much have the same performance (judging by the UI speed).
Haven't tried the SlimLP builds yet.
I also tend to return to the GPE rom. It's 5.0.1 though.
The reason I keep coming back to GPE is that I have pretty much no problems with it. Very stable.
In benchmarks you will get the same score on all roms. I got an average of ~32000 on all the above mentioned roms.
So, in the end it will come down to how the rom feels (fast ans smooth or slow and laggy) to the user.

Any experience with CyanogenMod? When I click the ROM tab, CyanogenMod is listed first so I'm thinking that it is the most popular right now. Do you have any info on how good or how stable the mod is?
Also, quick question. When flashing a rom, I know that I wipe the cache and dalvik cache before flashing. But should I also wipe these 2 after wiping?

Not necessary but yo can
ooer! woa there cowboy! It's new. Take your time to explore and understand how it all works then once you get that feeling that you're sure this or that could be better that's the moment when you can think about rom flashing.
I loved the phone when I got it. I then thought hey, I'll flash cyanogen on it. That worked well for a time (and they're getting better and better with each version).
I then went a while with a danvdh's excellent google edition rom (imho a very good compromise for the minimalist).
I finally came full circle back to a TW based rom (for info the Imperium v9) with which I am most happy.
Through all that I discovered that what I wanted most was an excellent camera, good video player and good battery life, all of which come included in TW roms.
The Imperium or other roms bring nice tweaks and optimisations all of which came from that famous itch that every geek has for making things that bit better.

If I were to play taxing games, which rom would you suggest? I'm in a tie up between Cyanogen and Google Play Edition.

In bechmarks both roms give the same scores. So there isn't much to say about that. CM does feel a bit faster in my opinion. But I don't know if it offers any noticeable advantage. Unless you're willing to run android 5.0 and ktoonsez kernel (which offers CPU and GPU overclock and Is only available for CM).

smooth and fast in nexus 6p

Wich ROM, mod, kernel or combination of two of them give me the best experience in android?? I m looking for an Android system fast, smooth and best battery life. Thanks to all
If something was the best, nothing else would be used as there's no point in using something that's inferior when you can get something better.
There is no best, I suggest you read each thread and pick one that suits your needs. Saying X ROM and kernel is the best is like saying a specific vehicle is the best...One may say a Ferrari and another may say an F-350. But who's right?
Some people like roms and kernels bloated with 1000 customization options filled with placebo "optimization and enhancements". Others prefer a clean, minimal ROM without all the useless bling that they'll never use.
P.S. there's probably 10 threads like these, and possibly 11 by next week that you could've read through. I'll just copy and paste this same post on the next one.

Currently using PureNexus nougat with ElementalX kernel. The experience is pretty good.
Using the phone for SMS/MMS, YouTube and web browsing. I can get ~ 5/6h sot with a full charge on WiFi and ~ 3h30 sot on 3g/LTE which is enough for me.
Also using custom CPU governor profile in EXKernel Manager helped me with battery life without affecting performance (at least not that I noticed). You can find more infos here:

Hope that helps
I am using the stock ROM with the ElementalX Kernel. Very happy with the performance of the phone. I arrive at the end of the day with 40% battery on average

F2FS + Dark ROM + FLASH kernel ! That's the best combination and I am a serial flasher
These people that are saying there isn't a best ROM, I don't really understand the reasoning behind this. There most certainly is a best ROM kernel combination. Otherwise all these ROMs and kernels would be exactly the same right? Sorry to say, some are better than others. This is just a fact.
If you want speed, smoothness, glass, breakneck speeds, great battery life, there really is one only choice.
Uber rom by Chad and faster kernel by Chad.
Why?
On f2fs, (trust me, you want f2fs) I have yet to find kernel or ROM combination that beats this.
Its the only rom that's built with GCC 6.3.1, and the only rom built with clang 3.9.1. Coupled with f2fs, this rom FLIES.
I have flashed every single ROM on this forum and then some, and I'm telling you this is the best combination you can possibly hope for:

Uber rom by Chad I definitely agree is the best. I tried using his faster angler but it caused problems with mods like viper4arise so I am sticking with flash kernel. Uber by Chad is definitely the best rom though and I have tried so many roms like pure nexus, resurrection remix, dirty unicorns, sixRom, lineage, cyanogenmod, nitrogen, Cortex and so many more.
Is the stock camera working on either Uber or Dark ROM with f2fs file system?
Thanks
There's no such thing as a best rom fact, but only best rom opinions, which isn't a good idea to ever discuss here. [emoji14]
As for battery, that all depends on you as a user to manager your battery life your way. I get 4+ SOT easily and I listen to a lot of music and text a lot.
As for what I'm using, I'm running ABC Rom with franco.kernel, root, and V4A. ?

In this link I download the Uber ROM, right?
And other thing, you say me I have to flash to f2fs first before install this ROM and kernel?? Or I don't have to flash previous?

I basically just wiped cache and dalvik/art cache and flashed the rom and kernel and all my mods. I also made sure to do stuff like rename audio effects and everything I did to make it work with flash. I use stable 2.4 deutronomy aroma installer. I was talking to someone else on this rom and kernel and he said he had the same problem too so it might be hit and miss or maybe you flashed it different than us. Please tell.me what you did to get it to work. Thanks
What partitions do you guys convert to f2s besides cache? Data as well? Everything else remains ext4?
Running stock has been great for me lately. Downgraded to 6.0.1 running Xposed for pixel mods. Amplify and greenify. With exkernel has been a great experience so far. Near 7h SOT yesterday. Will be going back to 7.1.1 soon, as the February update is out.. I heard lineage OS has good battery life. Will be trying that out soon in a few days.
Read the threads on XDA and good luck!!:good:
