Well first its not room, its ROM
Second
A ROM is android itself, when you install a ROM, you install a new version of android, and replace the old one, a ROM includes all parts of android
The main part is /system
That is what makes android look like android
/data is where all of the user stuff is stored
A new android installation wipes(erases all data) from both of these
A kernel is different
A kernel is a piece of software that runs underneath android and let's the operating system communicate with all the hardware that's on the phone, with out a kernel, your phone won't boot into anything
Kernels are very specific, you can't install a sense kernel with an aosp ROM, the kernels have to also be compatible with the ROM you want to run as well
Usually(in fact, its rare in the case that it doesn't happen), when you install a rom, you also install the kernel for that ROM, such as a CyanogenMod kernel and a CyanogenMod ROM, but not the other way around
If you ever want to install a custom kernel, install it AFTER you install a ROM, or else when you install the ROM, you will overwrite the custom kernel

Car analogy: Kernel = Engine, ROM = the rest of the Car,

Thanks you both for the help.
So which one is the best ROM for my T999?

Up to your preference, I prefer CM10.x, other prefer TW-based ROMs, there is no answer to that question. Look through and pick one, you don't like it, try a different one.

And if you run into terms or other things along the way, search xda for a lousy of definitions. There's a couple of pretty good ones that you may want to bookmark for quick reference. Also read the stickies.

Rom manger's poor selection for G2/HTC Vision

Why does rom manager only support two different roms for the g2 but has a much larger selection on other phones such as the droid or evo? I would like a little more selection than a kernel, nightlies for one rom, and one sense based rom to choose from. Anyone have some insight to why this is?

I never use Rom Manager to flash any Roms, I personally like to flash new Roms from recovery and actually go thru the process of wiping and installing the Rom myself. As for your question of why it only supports 2 Roms, I'm really not sure why.
EDIT: If found this LINK that might explain why, it looks like the ROM Dev's need to go thru the process of getting there Roms on Rom Manager, and maybe some of them haven't or dont want to go thru the process.
Exactly what he said. Its up to the rom dev to put it in rom manager and work with koush.

Is there more ROMs on the premium version of ROM Manager or does it just make it easier to update?

Premium just gives you access to the nightlies, sadly ... start asking the devs to submit their ROMs

I also manually flash my roms, and wipe caches and battery stats, but its just handy to be able to download it like a cm7 nightly and be notified about rom updates. Then from there I take over and flash it myself. But would like to see a variety up there that's all. I would be more inclined to try different roms I think. I've only had cm6.1.1 and about 75 different cm7 builds, between gridlocks build and when they became official nightlies.

S3 noob ... a few questions

1) Have any Mac users successfully rooted? I know there's a new release candidate for Heimdall, but there's no Mac binary yet and compiling from source is way over my head. And apparently older versions of Heimdall don't work with the T999.
2) For the S3, do you always have to flash recovery separately from the kernel? I just came over from the Epic 4G Touch, and those kernels had recovery baked in.
3) Which TouchWiz ROM offers the best "tweaked stock" experience?
Thanks!
1) no idea, I'm sure there have been Mac users rooting
2) yes we flash recovery and kernels separate.
3) all of the touchwiz ROMs are pretty similar. Try the ones that are still updated and find one you like is the best advice

Sorry, I don't have a mac so not sure bout that one.
I'm not sure why you would want the kernel and recovery to be baked together. Just pick your fave recovery and you can then flash any rom, mod, kernel, etc you want. Never knew they did it the way you were talking about. Sounds like it'd be a lot more work for tge devs.
Third one is one you will have to decide for yourself. There are fantastic roms here but my taste may be totally opposite of yours...

My personal favorite and most stable I have tried is Wicked ROM. The dev just released a new version.

[Q] Stock ROM vs Custom ROM

Hi!
What is better:
The official Samsung stock ROM or a custom ROM? And if second one, which? CM?
I ask this cause I heard that custom ROMs don't have that much support for the S-Pen. And no Multi-Window.
go for stock firmware. I was custom rom flash addict but after i got note2, i choose stock firmware+custom kernel
Me too. In the past devices i go for custom rom for it speed which varies alot from stock. But on the sgn2 i no longer need that as its fast as it is. I just keep to deodexed stock rom with mods which suits my needs.

+1 for me.. Stock deodexed with a custom kernel to get faster charging etc, I see no need to overclock with a device this fast :good:
But don't forget to disable all the lame bloatware too.
Could you link me to that custom kernel?
Are there any downsides to the custom kernel? Faster charging sounds nice.
That heavily depends on what you want. If you like some of the Samsung-specific functionality like S-Pen, Quick Glance and so on, you want to stay stock or flash one of the nice and debloated custom ROMS based on stock. My favorite is HyperNote, but I think it doesn't meet all your requirements.
If you want it even faster and like the Cyanogen-specific style, try any of these ROMS (hint: HyperDroid).
But there is no "need" to make the stock faster, as with this kind of RAM and CPU power, everything will just work fine. Best to make a backup before flashing and just trying some ROMs on your own. Have fun
Just get a deodexed stock rom and you will have everything you need.
What devs do is change the roms and repack it for flashing.
And in my case half of them aren't exactly what I need or are useless.
You can apply all those mods to yours without any data loss
And it's fun :beer:

I've not experienced any downsides, plus it patches the Exynos bug. You are trusting someone other than Samsung to control the internals of your device, but Im happy with that. I do get a random reboots now and then, like once every couple of days but I suspect its unrelated, and I do like to tinker with my device. Phones these days are actually computers and do trip up every now and then.
I use the Perseus kernel http://forum.xda-developers.com/showthread.php?t=1927852
I really would't worry about it. If you don't find it useful you can just flash the stock kernel back, no halm done.
Stock rom and kernel are good. The note 2 doesn't need a rom to be more fast or stable.
But for me is important choose the application that runs on my phone as system app. So I need root privileges.
Then I found some roms that had stock things without a lot of S.h.i.t. that samsung have to put into our device for marketing purposes.
And so now for me is better a custom rom because you know what there is and what is running on at least.
Should be in the question section.
Stock custom rom.
It's usually updated to the latest Samsung version, can be modded and has loads of tweaks
Hi i use omega v10 with redpill kernal and every thing works fine battery live is amazing and the rom still has all stock feutures

[Q] Questions regarding using custom ROM's

Hi all,
I'm fairly new to all of this. Have been on XDA before, but that was a while ago.
I don't like my standard Desire HD with 2.3.5 Android anymore. And there is no update for this.
So I thought I'd look here for a custom ROM which could be nice.
However, I've been told that a custom ROM has it's downsides. But before I just blindly believe those claims, I'd like to ask you guys to tell me what the truth is.
1. I've been told that there is no custom ROM which gives you ALL and every function. You always either loose the use of the camera, or the speaker doesn't work.
2. I've also been told that you cannot go on Google Play store when using a custom ROM.
3. They said that you cannot go back to the original HTC Android after rooting and using a custom ROM.
4. In most cases, a custom ROM will improve performance (compared to the stock HTC ROM).
5. And finally: they claim that when using a custom ROM, certain apps or games won't work.
I've got no clue about these things really, but I'm am kinda interested in the whole concept of rooting. I'm good with computers and learn fast, so I do think I can learn how to do this (eventually ).
Thanks.
1. False. At the very least, stock rooted ROMs like Android Revolution HD has everything working. For other ROMs, it depends.
2. False. Flash gapps if using an AOSP-based ROM and Play Store will show up. It comes with Sense ROMs.
3. To some extent, true. If you unlock the bootloader, HTC will know, even if you relock. And if there is no RUU for your original ROM you can't revert to your exact original ROM.
4. True. Depends on ROM optimizations.
5. False. See #1.
Great, thanks for the reply.
Seems for me that if I wanna use a custom ROM, I just need to find a custom ROM that will allow me to use Google Play Store.
Just wondering: what does RUU mean?

Any custom ROM will let you use the Play Store. If one doesn't include it preinstalled, it means that it's AOSP based and you just need to flash gapps. The OP of most ROM threads will have a link to the recommended version. A RUU is a region-specific executable distributed by HTC that installs and/or updates the stock ROM, bootloader, radio, and recovery.
Well, then it seems like I just have to learn what AOSP and Flash Gapps means .
Google is my friend.

GAPPS is Google APPS. Some roms come with all the google apps bundled some dont. The ones that dont you will need to flash the Gapps.zip file straight after flashing the rom.zip file.
Start with Android Revolution v6. Its all the same as you have got now, everything works. You can try v7 which is just a sense upgrade to sense 3.5. Both have gapps included.
If you want to try something new then give jellytime r10 or unofficial CM10.1. Both need gapps downloading seperatly and is linked to in the 1st post of each thread.
Many more roms available, happy flashing
Edit: neither of the last 2 are sense roms.
Thanks for the explanation and the tips!
Am I allowed to either open a new topic where I can ask which ROM is best suited for me, OR should/can I do that in this topic?
I've been browsing the topics in the development sub-forum, and most off them look great and sound great. Just not really sure if I should look for certain things.

Topics like that aren't allowed by forum rules. The usual advice is to try them for yourself.

ROM recommendations

Hi all,
I just bought a galaxy note 8 and rooted it. I installed the Cyanogenmod rom but dont really like it.
I do like that it is a lot faster than the stock software.
Can anyone recommend a ROM on here to try. I see there are lots available but dont know which one to go for. If anyone has one of the roms from here and loves it, please let me know so i can try it.
Also, now the device is rooted, i can just wipe and install ROMs using the clockwork recovery program right?
I've installed the CivZ-FLEX-BEAM-REV3.1 ROM now. Much smoother and looks more like the stock rom

Cosign. It's in my opinion the best performing ROM for my needs.
the number of ROMs is not that big, go and check for yourself - generally the "best ROM" threads are usually closed by the mods, rather sooner than later
Sent from my GT-N5100 using xda premium
Although the options are not in abundance I also would recommend CivZ-FLEX-BEAM-REV3.1 ROM I think it's the best for the note 8 & IMO one of my fav jellybean ROMs overall.
