A'ight lads, lets talk about ROM's and kernels. - Nexus 6P Q&A, Help & Troubleshooting

I've had my nexus 6p for almost a month with SPIGEN case, ROOT and TWRP(that wasn't neccesary). Been seeing alot of roms people have been flashing and kernals as well and I would like to put forward an question for all you whom have flashed roms and kernels. Which, in your opinion and testing, is by far the best ROM and Kernel. I would also love to see some modifications that you use in your Kernel for example governors and things like that. Also a side question regarding ROM, which one is efficient at outputting a good battery life and stable?

[Q] stock google rom vs LiquidSmooth

Hey,
I just wanted to ask does the custom roms really worth rooting? in comparison to the google stock rom how much faster and more battery efficient are the custom rom that specialize in those fields? (i.e. LiquidSmooth from what I could gather) and how much more/less stable are they from the stock rom?
Thank you.
Experience differs from user to user. The most conclusive way to get an answer is to try it out yourself. For me, PA has been just as fast as the stock ROM and had equally good battery life, but I have had the occasional random reboot. To me that's a miniscule trade-off for the features you get. You won't really get a ROM that's significantly faster than a stock ROM though because the hardware on the phone is good enough that everything feels fast.

I would recommend you try both and stick with the one that works best for you. Only you can determine which one you like more. The N4 is easy to install a custom rom on (even from stock). Plus with the backup apps out there you don't have to risk losing your data and starting over. No two users are identical and what works for one may not work for another.
For what it's worth, I've flashed back to stock/locked/unrooted because I never came to depend on the features the different roms gave me. I'm getting older and don't have the time to stay current on the different roms and features. All I need for my phone are apps/features that are found in the stock rom and the google store. Battery life is better on a custom rom but it's not worth it to me to continue my "flashaholic" ways. I still get through a day sometimes a day and a half on the stock rom - which is all I need. My use case could be drastically different than yours so don't do what I did unless you know it will work for you.
The developers here do great work and it's a great community so I would recommend you try them all to see which one you like the most.
Good luck.
You need to find the answer yourself.

its not about me testing for myself because i'm not looking for features or special stuff i can get along with everything i'm really just looking for the fastest most battery saving ROM, thats it, I play little to almost no games basicly mail and scanning and stuff like that(i'm a student right now) and soon i'll be writing some apps for myself for security purposes so I need something to really milk that Quad Core for all its worth so I also need some CPU tweaking apps(not sure if thats ROM related)
You'll be very happy with Sabermod or Rasbean both close to stock. Sabermod is the only Rom built using the 4.8 chaintool and is very fast. The battery life is also excellent. I recommend those 2 for a close to stock experience with some useful tweaks both fast smooth and solid.

Thank you for your input.
Any other opinions?
and by the way, excuse my ignorance but what does it mean 4.8 chaintool? what makes it faster then the 4.7 or the older ones? and since its really new im guessing, does it mean its less stable then the other ROMS? and when you say excellent battery life, its in comparison to all those other ROMS that aim for max battery life?
Thank you!
If you really want more battery life or smoothness then IMO you should just install a new kernel; Franco's kernel has great battery life but it still has better performance than stock, Trinity kernel is super fast and smooth, and there's loads more options available.
I'm running CM10.1 and Franco kernel and its very stable, barely ever have any sort of bugs or random reboots

I run CM10.1. Close to stock, but has a few options that are nice to have especially if you like to customize your phone. There are other Roms that have more options, but to me, what's in CM is enough. It's really up to you.
With that being said, I recently flashed a stock rooted rom and got MUCH better battery life than on CM. I don't know if it was an app I had or what, but stock definitely gave me better battery life. I have tried kernels and Rom combinations, but always come back to CM with every single phone I've had. But, in my experience on the Nexus 4, stock Rom gives me the best battery life.
For me liquidsmooth is brilliant! Extremely fast while having tons of customization options. Pair it with matr1x and it really is a great combo for speed and battery life. This is only my opinion but it works for me. I got over 22000 on antutu with this combination (no overclock) while I think its around 17000 on stock. I also get significantly better battery life compared to stock.
if you really want a bump in battery and performance, i suggest rooting and just install francos kernel.i've tried every rom on this forum and for me i ALWAYS find my way back to stock for me it just feels the most fluid and everything works like it should. like me you dont play games or anything and im no app hoarder.that said stock rom with francos kernel gives me the best of everything including color/gamma tweaks to make your screen look better with his app.
with that said i suggest to check out different kernels

Now, if we install franco's kernel onto the Stock ROM, will this prevent any future Google updates from being installed?

Updates in any form will show up in the forum and no need to simply rely on Google for them. They have recently released an updated kernel which I see being implemented by some rom developers and kernel developers already. Let's understand what we have here guys, a community of constant building additions/updates to our phones. So updates should be the last thing for you to worry about IMO
Also to me OP some of the questions you asked can all be answered with a simple Google Search, not that the answers given here are wrong but you would probably find more in depth and uniformed answers by looking it up.. Quite sure its on a wiki somewhere...

I believe he means Google ota's and yes it can stop you from getting ota's. Any modification to system. Whether you added or removed something will fail. You would have to be on complete stock for it to work. Just download yourself a nexus 4 toolkit. The latest factory image, latest drivers, and make sure you backup your internal storage on your computer. Use the tool to return your phone back to stock. Of course whenever you feel is tge right time to do so.

Oh no I fully understood what he meant and my point was simply people unroot or stay stock to wait for an update. Whether you are rooted or not the update will find you in some form. Either with a rooted stock rom or a custom rom but rest assure that xda will not let an update happen and its not on everyone's phone :good:

[Q] Which rom is currently the best for nexus 4?

I have switched from HTC One X because I hate its quiet speaker sound and GPS jumping around. So far i am really happy with nexus 4. Currently I have it stock rooted. But Im just wondering if I should flash a Custom Rom because I am currently really happy with stock root. But is there battery improvements .etc. with other roms.
I have my eyes on Cyanmogen and paranoidandroind but I think they both are buggy?

There is nothing like the best ROM.
For one person best is stock, for another, best is heavily modified.
Personally i use AOKP (milestone1), and for me it's virtually bug free, with healthy dose of improvements over stock, which I got used to on my old One X
basically this is nexus, so pretty much all ROMs are stable
they're built from exactly same source as stock. it's not HTC where published source code won't even compile properly without intense troubleshooting and fixing.
Both roms have been around for a quite along time so bugs are at a minimum level or none at all. Every rom will have a few bugs here and there that's why there are releases to fix them. Both CM 10.1 and PA are pretty stable and prefect for daily use.
If you're happy on stock then there's no need to flash a custom rom. There's no such thing as "the best rom".

another of this best topics...There's not a thing like "best" rom, what you can find however, it's a rom that fits your needs better than others. If you think the roms you're looking at are buggy, then don't use them, custom roms are always a work on progress unless it's a final version, so deal with it.
Both roms have a complete changelog and you can find what's working and what's not. they bring different things to the table, for me Cyanogen+franco kernel do the trick.
Interesting answers I guess i'll stay stock for a bit longer. I was tempted with custom because battery currently is alright. But just wondered if there was a custom rom with like battery improvements.

Roms don't contribute much in battery life. Kernels do. Go for a custom kernel.

a lot (or at least some) of people report, that battery life is much better after re-flashing stock rom. apparently something to do with factory flashing method. after reflash they gained extra few hours between charges.
personally can't say much as i didn't ever boot my nexus on stock, oem unlock was the first thing, and straight after flashing custom.
about kernels - try franco. He's got years of experience with custom kernels for different devices. Plus a lot of new settings to play around (when using with his paid app, but IMO it's worth it) - voltage, frequency, display contrast, gamma etc... tons of useful tweaks.
Kernels alone are worth it for the screen color adjustability. Try a bunch of roms before settling on one, most are plenty stable.
Depends on whether your looking for customization, or performance. Not saying it's the best ROM/Kernel combination, but I use RasSaber with franco.Kernel currently for performance :good:
After trying some different ROM's I settled on SentinelROM: http://forum.xda-developers.com/showthread.php?t=2233740
It has ROM+kernel tweaks and gives good battery life and performance right out of the box. Plus it's based on CM 10.1 source, but optimized for the Nexus. So for me it was the best of both worlds, and I'm very happy with it. It's very stable fast and gives you 48 hours of battery with moderate use.
I have to say... I was skeptical about rooting my Nexus 4 because I didn't want it to mess up in any way but then I saw ParanoidAndroid3+ and immediately rooted my Nexus. I've been playing around with it and it is awesome. I haven't bumped into any bugs or problems yet. I'm very pleased! :thumbup:

Kernel and ROM

KTManta vs Franco
and which ROM is the best, pro n con please.
sorry, im really new at this.
Well, neither are a ROM, and neither are best or worse. It is all about what you are looking for in a kernel
Troll thread? There are stickies if you're being serious.
Each thread respective to the developer will have a summary of their kernels.
Pros and cons can be read in the threads as both are fairly new for the Nexus 10. You won't have to read too many.
I'm using KTmanta as it doesn't give me reboots on kaos rom. I was on Franco on PA but the instability was too much.
Sent from my Nexus 10
It all depends on your specific needs. I use RasSaber + franco.Kernel, but I can't say it's the best (I haven't tested every other ROM/Kernel combination) or if it'll be the best for you. I prefer minimal customizations with speed, but others want customization and speed, others just customization, etc.
Yea they are all great kernel, it is just a matter of finding what you feel is best for you. I mean I jump around between all three kernels of Trinity, KTmanta, and Franco love using them all and I bought their apps. Each one offer something different, but in the end it all depends on how it is for you. As for me I went back to KTmanta from Franco using CarbonRom. There is no best just what is good to you.

Stock but looking to change

I'm on stock 4.2.2 at the minute but I've rooted / unlocked the bootloader. What I want to know is which ROM(s) / kernel(s) would be best to improve battery life but also add additional features? I know everyone will have their preferences but there's quite a few ROMs out there and I don't have lots of time to reflash over and over so I'd like to know which ROMs and kernels are generally considered as the best for additional features and battery life.
Thank you.

Lots of good rom`s and kernels available. You have to try them out yourself and keep the one`s you like most
I was thinking of flashing Franco's kernel and staying on stock. How do you find it?
The best ROM and kernel is what YOU like the best. This will be closed in 3 2......

For me it works great. Good batterylife, color/gamma control and performance :good:
While most people will tell you that ytou have to find out for your own because everyone is diffferent. Thats true, however it looks like your are asking for our personal opinion.
Paranoid Android hands down. The most innovative ROM out right now. Other have now started to inlcude some of their features in their roms, so that tells you a lot.
Cyanogen- This WAS the most innovative ROM before PA, its still however the most stable when it comes to bugs and tweaks.
AOKP or Carbon These 2 roms are awesome however Carbon is made from CM i believe with their own twist and tweaks.
Thats my take on it, howver take a look at this article, its a great read on the top Roms and why.
The kernel matters most for battery life. Franco kernel is the best one I've tried for battery life. Stock rom or cyanogenmod seems to be a tiny bit better for battery life but honestly it might just be a placebo effect. What I do like about cyanogenmod is the fact that you can adjust the auto-brightness levels of the screen. So if you want a dimmer version of auto-brightness you can do it and save battery life.

[Q] General questions from a new owner

Hey guys, I recently bought a Nexus 4 (I will get it tomorrow, but will have to wait more for screen protectors and case) and coming from an Xperia T it's like I'm a kid in a candy shop; all those kernels and ROMs, my head is spinning.
So my plan is to enjoy stock Android for 15 minutes and then root/unlock the device right away. Now, couple questions for you guys:
1, I've seen some Linaro builds of both ROMs and kernels here and there. Does it speed up the phone much? Does it make it worse (see: overheating)? Also, I don't know if I can run a stock toolchain ROM with a Linaro kernel or vice versa. How about that?
2. Regarding the kernels, I'll never stick to stock so will change to a custom one. I heard faux's and franco's (remember the latter from his very first release on the Optimus One ) are the best ones on the market and they both have customization apps. Now for what I've seen, faux's kernel provides more customization on the app, but don't know how does it perform in real-life situations, nor I do with franco's (altough I tend to prefer this one for the per-app settings). Could you guys give me some informations about this?
Thanks a lot

1. 4.2.2 ROMs and Kernels are inteechangable. You can use any kernel with any ROM, even the stock one. However, with 4.3 , you have to match the build number of the ROM with the kernel type.
Sidenote : The Nexus 4 does not normally overheat. The glass gets warm because it's a good heat conductor, and pulls the heat out. Don't worry about it.
2. While Franco seeks to be the perfect balance between performance and battery life, faux gives you a choise: either performance or battery life, or both, in a balanced way.
I was in a similar situation as you are about a week ago. I came from a Galaxy Nexus and couldn't wait for my Nexus 4 to arrive. I too spent a lot of time in the Development forum trying to figure out which ROM would work well for my needs. In the past, I have never run stock Android. However, that was before the launch of 4.3.
Right now, I am still running stock (a whole week later!) and am really enjoying the smooth experience. With root, I can use Xposed framework to implement the few mods that I like.
Overall, I am very happy with the device. I'd give stock a try - at least a day or two, and see if it meets your needs as well.
Thanks all, I'll give both a shot. I'll give stock a shot too. First days will flash ROMs on ROMs and I will find the stablest for me
Sorry, but this is "what is the best rom/kernel" thread. Try them out for yourself and see what works for you. You mentioned some of them so just flash them first and see how they work, they're free. Personally I like franco and semaphore kernels, Neo is a good kernel for performance too, for roms I stick to the big names like CM, AOKP, SlimRoms and Paranoid.
Hey Bytecode,
Try slimbean, you probably remeber popdog's slimbean for p500, it is 10% of real slimbean on good device You will not need any custom kernel with it.
