[Q] i am using s5 SM-G900H

i have rooted my phone and now i am searching for custom roms i am new to xda please provide me the best rom link

There is no best ROM anymore than there is any one best car or vacation. It depends on what you are looking for and you gave no hint of what your priorities are.
Moreover you have a niche model. There are a lot of custom ROMs to choose amongst for Qualcomm S5's. However you have an Exynos based handset which comparatively few people use and which is incompatible with the Qualcomm models. This means that few custom ROMs are available for the 900H simply because few developers own the model that you have. Have a look in the android development subforum to see what is available. The last time I looked it was ony stock or debloated stock ROMs for your variant.

in that debloaed rom we have Odexed Version nd deOdexed Version wat z the difference

One is odexed and one isn't. Simple huh?
As a simple search would have shown you, stock firmware apps are odexed, while few custom ROMS are. Odexing is where an app is split into two parts ostensibly to make them load faster upon boot. Odex is a pain in the neck if you want to modify a system. It's sole advantage is that it may reduce your boot time.

easiest rom to go with that includes everything like modem and gapps and such.

What is the best rom to go with that has the modem and gapps included? also one with good tethering/hotspot so I dont gotta be subject to carrier extortion and rape... LOL.
I want something easy to flash and stuff since I am not the best with this sorta thing and money is tight. So can't afford to buy a new phone.

Stock based ROM.

I don't have a lot of time.. That's why I posted here.
Ordering phone on Monday and going on a trip wed.
Wanna have the ROM by then with the least amt. of issues with straight talk.

Stay with the stock rom then. Most custom roms don't have gapps included.
Also, most custom roms require you to have a custom recovery. This requires additional flashing and time.

well I know about that but just some roms don't have modems or other things and I don't wanna have to search manually for stuff that's why I asked here !!

They're recommending stock because of the amount of time you have available to you before your trip. If you seriously want to flash a custom ROM prior to your trip, then you want to flash a Cyanogenmod-based or AOSP ROM. The question is, which version of Android do you want?
If you want Android 5.11, install Optimized CM12.1 + GApps.
If you want Android 6.0, AOSP 6 + GApps. If you want the goodies normally found in a Cyanogenmod-based ROM, then you want Synergy or CrDroid + GApps.
All the ROMs recommended install quickly with TWRP as your recovery. Keep in mind however that every ROM, even stock ROMs, will have bugs. However the bugs in the aforementioned ROMs will not prevent you from using the device. The good news is that unless you use a CDMA device such as a Verizon or Sprint Galaxy S4, you should not have to worry about which modem you have. The same cannot always be said for the Touchwiz ROMs, but even then, unless you have a pre-Android 5 modem you should be OK.
For Touchwiz-based ROMs, look at the ones available from Albe95. Regardless of which one you install, keep in mind that the package is much larger than Cyanogenmod or AOSP, and thus will take longer to install. Albe95 generally recommends the latest modem for your device, so if that is a deal breaker, then go Cyanogenmod/AOSP.

I want 4.4.x or 5.o for some of the betas I'm testing.
Will the ones you recommended have the modem included. I'd hate to have to hunt n peck n trial n error with that.

Custom ROMs do not include modems, period. If a ROM recommends a modem, you'll have to get it from the appropriate thread. I can tell you that AOSP and Cyanogenmod do not require a specific modem. For example, I'm running AOSP 6 on Straight Talk as we speak. I never upgraded the modem from the Android 5.0.1 version I installed seven months prior.

so CM doesn't include it? that sucks. what one do you recommend? and how is that flashed?

As mentioned, no custom ROM includes the modem in its download, because unless the ROM specifies otherwise, you use the one already on the phone. So in the case of Cyanogenmod, there is nothing special to do. Simply install the recovery through Odin, boot into the recovery, and install the ROM.

[Q] [noob] ROM+kernel flashing, help me find a proper ROM+kernel?

So i want to root and flash a custom ROM on a stock GT-i9300i (S3 Neo) on Indian base-band, running 4.4.4
I want to go from this stock to AOSP based (or CM/RR) ROMs, for flashing Xposed framework and the likes.
I have done research looking for ROMs in this phones section.
I do not mind using android version 4.4.4/5.1/6.0 ROMs, I will flash whatever android version fulfills my requirements, which are:
Required is: Front+Rear camera should work, and Dual sim should be supported (still, for information, SIM2 will be rarely used, so audio in call issues on SIM2 can be ignored)
And so my question is: What ROM+kernel should i flash, as daily driver?
In advance, thank you for your help!:fingers-crossed::angel:

use cm12.1 offical

Basic Qs about Custom Kernels and ROMS

I've been mucking around with Android for a while but basically stay with a ROM and what it comes packaged (or recommended) with.
Recently I've been looking around at Custom Kernels and I see they offer different options and functionality, but I lack some basic information:
I am guessing that the Kernel and ROM have to be compatible?
Is, for example a Kernel like Blu Spark or Lighting (all for OP5 and Nougat) compatible with all OP5 Nougat ROMs or is it ROM by ROM?
I looked over the pages for both Kernels and also for xXx Freedom OS and didn't see any information concerning compatible ROMs or compatible Kernels, is there any place/list that shows the compatibility of ROMs and Kernels?
Any information, or guidance to where I can find it would be appreciated.

Very simple.
There are 2 types of kernels. One which only works on an OOS based (custom) Rom, and one which will only work on a LOS or AOSP based Rom. Most custom kernels will work on every LOS or AOSP based ROM. But... There's one negative thing about flashing custom or OOS based Kernels. You will never know how the Kernel and/or ROM will behave. There's no 100 percent guarantee if a custom Kernel or ROM are made for each other. Even if a Kernel which comes with the ROM is no guarantee for working properly. There's no such thing as "Stable" even with ROMs. Because stable doesn't exist in a Dev World. It will always be a never ending story.
Long story short, search for yourself an satisfying combination. If you found one combination you like, stick with it and motivate the Custom ROM Developer and or Kernel Developer.
Edit: as you can read i cannot give a proper answer to your questions. The reason why a Custom ROM Dev doesn't show a list in their OP for working Custom Kernels, is mainly based on the fact that they don't like if a user flash another Kernel that didn't came with their ROM. Mostly to avoid non related ROM issues. Besides that, if you made a decision to flash a Different kernel, along with their ROM, you're on your own.
Sorry for being off-topic.

Each kernel needs to be build for each rom. Well not each rom. Each rom based on the top three. OOS, AOSP, and LOS. As each has their own kernel.
If you use LOS 14.1 or RR, then youll need a los kernel. If you run stock OOS. Freedom or xXx, youll need an oos based kernel
Not all devs build their kernels for los or aosp. Me as an example. I only have mine built for OOS and It wont work on los or aosp (well it may but you are 99.999% likely to run into a lot of problems)
I hope that clears it up a tad bit

@lekiaM You provided a great answer and thank you. I did notice that some developers (xXx NoLimits) provide the option to select various Kernel during the install. I pretty much expected that matching a Rom to Kernel was a crap shoot to certain degree. I am going to try a few out and see how it goes.
One final question, if a Kernel offers functionality that is not offered in the original Kernel, how do you go about taking advantage of the added functionality?
Will the Kernel add those selection to the settings or will I need a different app to access them? I was thinking in particular of the don't wake on plug/unplug. I utilized some ROMs (CM) that had this feature in the setting, I use Freedom OS now and don't see that in the setting, but I see that the Blu Spark Kernel offers access to that function.

It does thanks. Prior to selecting some ROMs to try, I read that AOSP required a specific ROM so I steered away from it, for now. Until I am able to become a little more familiar with the entire subject.

An aosp based rom will install and run like any other rom you decide to flash. It comes with the stock kernel built in
Each rom has their advantages and disadvantages. Currently Im running xXx 4.0 which is OOS based with extra features and then of course my own kernel for better performance and battery

@noncomjd Good question. And honestly I've been wondering that too (most of the time) i could gave you a simple answer on that, but i wont.
A Kernel can interfere with the ROMs behavior (for example manipulate the vibration, sounds, led light strength, button behavior and so on.) But a Kernel has their limits too and also the Kernel Dev in question. Besides that , i did saw some very strange things a Kernel Dev can do to manipulate a ROMs behavior. But i wont go further in that.
Answer to your question:
Yes. A good kernel dev can overwrite or add some tweaks in the ROM itself (you won't see it while flashing, but believe me after that, some things in settings are missing or added in the build.prop) . But as i earlier said it has their limits. A good Kernel Dev is aware of their capabilities. And they mostly play save. If a kernel Dev mentioned or added a feature or something in their changelog, than the feature is there. But to enable or disable that feature, you mostly need an 3rd party app(like a Kernel Manager) to activate or deactivate their added feature.

You need a kernel tweaking app in order to change kernel settings.
You can change those settings even if you run the stock kernel, but it won't offer as much features.
There are many kernel tweaking apps available and some kernels even provide their own apps.

Thanks all for some great information. Have a good base to set out exploring a little more.

How do really stock rom differs from custom roms

If we want to run a rom he can't (directly) we have to wait untill someone made it specifically for us. Thats fine i got it very device have its own kernel and rom integration. But if a person is using the same exact tree as official one do then why it is difficult to run stock apps directly w/o proting them.
Is it because of some legacy or copyright problem. One can build a rom on its own w/o having a team(like los, rr, paranoid).
Why porting is necessary? I would like to know that too

Cause you dont have updates

I am not a code/programme guy,
But what i have learned is, these different ROMs (Stock, AOSP based, Lineage based) have 0 (zero) interchangeability to their stock apps (except common apps). These may be because they use different codes?
For example, lineageSU addon will work only on lineagebased ROMs. Moto apps will work only on stock.
This looks like this apps are coded in way that it run only for specific ROM/device,
If you want such apps you need to modify it..
About ROM,
There are 4 sources/trees, 1)vendor 2) device 3)ROM 4)kernel.
Vendor, kernel, device tree can be used same for any ROM,
but ROM source is different for each ROM, which defines what is base of that ROM. You cannot build stock based ROM, you can only debloat,deodex, and modify stock ROM...
So, on different ROM, you need to modify apps to run...

@DgnrtnX I recommend to read that article about blob's so you get a better understanding why there's so much effort needed to "port" apps for example: https://www.xda-developers.com/came...opers-make-hardware-work-without-source-code/
