[Q] [NOOB] Help building custom ROM for S5 G900H

Hey guys
I'm currently working on my first custom ROM mainly because there are currently no ROM for the dreaded G900H (aka Exynos) version. For this, I already downloaded a stock ROM and created my environment using Android Kitchen. So here are my questions:
1. I was able to follow and execute all the instructions to extract the custom ROM, install root and busybox. But first... is Android Kitchen even compatible with Galaxy S5?
2. Is it important to keep the CSC info on the new ROM? How can I backup current CSC info from my stock (carrier provided) S5?
3. How probable is to brick the phone if I flash a very alpha ROM as the one I'm supposedly cooking? I already have a nandroid and EFS backup
Thanks in advance for your answer and patience.

Funny, implying that this is an statistics game. It is not and it's ridiculous to blame developers for the lack of support.
Pretty much everyone that actually develops got the Snapdragon variant, if I had a choice I'd gotten that just by the amount of code and AOSP possibility.
Exynos was only supported by a couple of devs, it's all Samsung's fault - not devs. None of them currently has an S5.
Use xposed, greenify, titanium backup and there are few reasons you'll need a custom rom.
Xposed opened a new world of possibilities to modding.
Edit: Exactly that demanding attitude is what puts devs off. Other regions are usually more polite and grateful and that's something devs have noted in the past....

Sorry if I didnt make myself clear. English is not my first language. When I mentioned the millions of user was only to imply that more users, the more chance to have a genius among them. I didnt mean to have a demanding attitude. I was trying to say "Iknow you are out there, I know you are developing something for all of us. We are here waiting for your effort.

@CiDev:
You want to share your ROM for "H" here?

i dont think that will we have any custom rom for our model
but according with this http://forum.xda-developers.com/showpost.php?p=52168627&postcount=168 @Shohat told me that he will release custom rom until end of may,,but nothing..
maybe he is busy

I wouldn't bet *anything* on it being released, it looks to me like an abandoned project...
The whole 'I can't work on this because I don't have money' turned me off instantly from that ROM.
On topic: I have been working on a custom kernel for our device, mainly trying to improve battery life. I'm still testing, if it's worth it, I can release it.
It's based on the contributions of others, so it wouldn't be fair for me to keep it private, I just don't want to release something that will break stuff.

1 - yes.
2 - make an nandroid before
3 - if you have a brick, restore from your nandroid and ready again

[Q] Different Threads for GPE and normal S5?

This is directed toward the Moderators - Seeing as the Google Play Edition is a different phone than the normal SM-G900V, can we get a different section of threads for each??
I don't post a lot but I spend a lot of time on XDA. I'll try just about anything with my phone, but I am by no means an expert. I currently have the VZW SGS5 (SM-G900V). I am rooted with Super SU Pro installed and working great (SU Binaries updated and Knox Disabled). I have just installed Xposed for the first time and am looking for other things to do with my phone. As soon as SafeStrap or another method is working to install Custom ROMS (TW Based or otherwise) I will most likely do so asap.
Maybe I am not understanding their similarities, but it seems logical to have different threads for these phones so that we don't have to sift through things that pertain to a phone we do not have and possibly even try to install something that is not meant for our phones.

After we get some kind of custom recovery for the retail version like safestrap I would like to see all the DE threads moved to the Verizon Galaxy S 5 Original Android Development section like it's done in the VZW Note 3 development section. It would cut out a lot of confusion as well.

[Q] Just a few questions!

Hi fellow G2 users!
Got my G2 a few days ago (I know I'm about a year late) but this phone seems awesome. Model is D802.
I did a lot of reading before doing anything and so far - I am on stock LG rom, rooted, installed TWRP with autorec, flashed a volume mod and installed xposed with g2 tweaksbox. So far I have nothing to complain about.
Anyway, now come the questions - my previous phone was a sensation, and to have that fully ready to flash, it required unlocking the bootloader, S-OFF, radio flashing and root.
1. Is there anything else I need to do here? This is my main question. I did a lot of reading before posting this or doing anything to my phone. I only do something once Im completely sure I know how.
2. I've read about flashing modems of some sort and came across this link - xda wont let me post links for the 1st 10 posts... Its a site like codefi.re/autoprime
Can someone please tell me what the 4 different versions of the D802 files are?
3. Any recommended ROMS/kernels that are absolutely brilliant? I know that all devs make great roms but with specifically battery life, STABILITY, and all the LG features (like knock on and the new message reply box thing and quickmemo, etc) I have heard a lot about Pardus. Might try that out soon if I dont get any other recommendations.
4. I read about Jishnu's camera mod. The links have been deleted from his thread. Is it okay to ask if anyone has a backup? I would like to try it if possible.
5. I read about Viper Sound Mod. Is there an updated method of installing this on stock rom? The thread I found seemed outdated and half the links were invalid

Nobody?

Depends on what you want. Have you researched aosp roms? All the things you looked up are fine. Tweaks for a ton will help enrich its use but to change to a complete different operating system is what you should try out if you want to see something different. Modems usually come with the rom. Make sure you flash the correct variant for your device.

Going crazy - ROM and Kernel suggestions please

Hello,
I recently rooted my Galaxy Y and installed CyanogenMod 7.2. After spending time trying to get Google Play to function (I have tried different things and searched on here) but being unable to I decided to try another ROM.
It seems very hard however to get straightforward and comprehensive details on here for anything i.e. whether a different kernel is required, what the installation procedure is in terms of wiping and mounting things. There seems to be a lot of assumed knowledge when things are posted.
So, can someone please recommend a ROM or ROMS with links to precise instructions on installation. I'm looking for something stable, quick, clean and customisable. Things that sound like they might suit are AOSP, EVO and Oxygen.
Thanks in advance.

I see a pattern emerging - lack of guides

Hello! This will be a quick post about how it was good earlier and how it can be better today, so please, stay with me.
I've been using Sony's for a while now, starting with small and cute Sony Ericsson k510i, then k550i, then wt19i (LWW), and then Xperia SP. My "flashing career" started after I've lost warranty on my k510. At that time there wasn't a lot you can do to your phone - there were several official firmwares, various customization options, and a lot of custom patches. No competition, one latest official firmware, a big library of patches that you could port to your device, if someone didn't do it already. The only competing area were a lot of graphical patches, but you could compile them together on your phone. Like today, if you were doing something wrong with your phone - you'll get a brick and it's your fault. But for every device there was an instruction, a beautifully crafted instruction on what to do and how to do everything, step by step. Almost every thread included a complete set of links to get you started. If you needed to flash a customisation after installing something, there would be a link on how to flash custom right there.
Today I have my XSP and try to do something to it. So I open one link (non-sticky, needed to bookmark it), see a lot of ROMs, part of which are no longer maintained. Finally open one of them based on performance rating, and see that it needs some kernel. So I go to kernel list, and see that it can't be flashed without recovery. What recovery? One specific recovery, because another one can't flash it. Now how do I flash recovery in the first place? I need a manual for that. Now I go to kernel and ROM page and see that no manual is available for them, too. So I open main device page and don't see any manual, so I open a sticky thread. And guess what? I don't see manual there. And that's when I start a new thread, type my problem in, and see a non-sticky thread with last post made 2nd of May 2015, and no pages link to that thread at all.
Is that how it goes this days? A newbie comes in, spends whole evening, opens 10 tabs, and still can't find anything relevant? I think we need to do something with this, revisit old threads, compile a new one-for-all guide, or at least a list of guides. And stick it, so people can actually see it. Otherwise there will be small closed community of those who already can develop and flash, and all the others who either got brick or is afraid to get a brick. Thanks.
---
UPD: And then I see that the kernel which I almost decided to flash is closed and all developers migrated to another one. I'm talking about tangerine and helium. Again, no info in the first post. And main developer openly says to users of his work - if it didn't work for you, don't use it. What's wrong with you people...

I'm deeply sorry if I offended somebody with my previous post. I'm happy that you guys do such amazing things with this 3 year phone. But damn, FULL INSTALLATION took about 10 minutes, counting PC reboot into linuxes to get fastboot working. In case someone struggles like me, use CyanogenMod instruction to get to Cyanogen Recovery; download TWRP Recovery, ROM of choice and GApps of choice; place all three ZIPs onto your sdcard; go to recovery, flash TWRP, reboot into TWRP (by pressing volume rockers while loading), do Wipe - Factory Wipe, flash ROM, flash GApps, reboot to normal. Wait for about 5 minutes (black screen is normal, there will be dots flying after a minute or so to keep you entertained).

Yes, It's that simple nowadays, so why bothering typing so much? I was in that situation with my SP, too, but if the are so many answers to these questions and so many threads... "You have to read" is the answer! A lot! It's for your own good, trust me. Now I can do anything I want with my phone with nohow! So a little reading and searching here and there is just positive experience for you. Don't complain, the people here ( well a part of them) are hardcore coders or themers or whatever. You can't just ask them to tell you all the stuff. If want help I'm always available.

Thank you for linking to my very dusty and lonely Flash ROM guide hahaha
No you didn't offend anyone at all. The guides are actually there, like how to use Flashtool, how to unlock bootloader, how to flash recovery and everything, it is just that they are buried deep with time as the development goes. The thread are there, in the General section and are awaiting to be searched. Though some are outdated, some are not and you can benefit from there.
Some searching will normally do, but if it didn't, just ask in the threads, someone will probably answer to you!
I always have my eyes on the General and Q&A subforums of the Xperia SP, and I will usually respond to a help-able problems. So if you have any problems, feel free to post in the Q&A subforum, and if not me, someone will help you. If there are nobody, don't feel offended. Maybe people don't know what to help or suggest (but lets just hope that is not what it will be )
About recovery, PhilZ and CWM is way outdated, and its time for everyone to make TWRP as a standard as it is a still updated recovery. Cyanogen Recovery in my opinion is crap as there are far too less feature plus, it enforce on signed flashable zips.
About the thread on Tangerine, the developer said dont use if it doesn't work is because of the norm of the Kernel. The kernel is made by using an AnyKernel template, hence render support for almost all Lollipop ROMs. Since ROMs can be updated and all ROMs have different sources, a simple change in the system part can render Tangerine unsupported, and the developer cannot do anything (definitely his choice, please respect that) to only fix the problem on one ROM which could possibly break support for the majority of the ROMs! This also appplies to Helium. Therefore, his words of "dont user it if it doesn't work" has a meaning, and it is not something to degrade new users and so.

Thanks for the answers and offering help, happily I was able to install my ROM of choice and it still works flawlessly, I was even able to squeeze 20 battery days from my old XSP.
Thinking about it, I start to understand why that dev answered like that. I was a python dev in the past and know how one feature can kill two others. Just in my head there is one current linux kernel, and all things that are developed should work with that particular kernel. Kernel comes before OS, if you will. Isn't it the case with ROMs and droid kernels?
About TWRP and reading: I honestly did read a lot of info before doing something, because it's my only phone these days. But it's so hard to find information on whether something is deprecated or not. As a new user, you wouldn't just google "is this deprecated and no longer used?", because that search will not provide any info. That is why during that evening and following morning I lost count of how many times I just shaked my head asking which recovery/kernel should I use and how do I install it? Latest being the easy one, because I already found TechnoSparks thread by that time.
In case anybody is interested, I installed Candy 5 on default kernel. But I still don't know if installing android 5 on a kernel used with android 4.2 was a good idea. It went well, however.
