[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

Alliance Rom Tester Needed

Hi everyone,
As the title says I need some experience members to Beta test Alliance Rom for the Snapdragon Note 4 (5.0 Lollipop TW Base). If possible, I need you to be experienced in your phone, I know its new =), grabbing logs, able to report any fc's that may arise or be able to run a ROM that may not be fully functional (meaning some of the custom features added) I know this is a long shot but also if you are eastern US time that would be GREAT!
Please pm me for further instructions or you can contact me on Telegram @lacoursiere18. Thanks!
Brian
PS here are some links to the S5 Rom that was recently released just in case you are not familiar to our work..

Roms for Dev Edition

Hi all, there's been some back and forth as to which ROMs work on the dev edition. I decided to make a thread to list the ones I've tried and work. I figured we can share which worked and what you did to get them working (i.e. change APN, kernel, etc.). Thank you devs for sharing your great work I've used the following successfully:
Definitive
CM12 (known bugs)
Firekat (in T-mobile thread, daily driver)
Stock
Rick's

Well considering that there is no root available for the retail version it would make total sense that roms posted in the development forums are for the Dev edition of the device. I don't believe there is any question as which roms are for the Developer Device.
Edfunkycold
Have a great day!

I think he means Rom's that work versus those with too many bugs as opposed to DE vs RE rom's.
For this to be fully useful I would suggest links to the forum post for each Rom and listing out the different CM12 variants (AICP, PAC, etc.). Thanks

What I meant was, "I tried ROM xyz from the tmo forum using ABC kernel". I apologize if it wasn't clear enough. Some folks have successfully ported Roms that were for a different carrier.

My suggestion is that you edit the title also the other user has a great idea to post links for each one so you can actually have a help thread or index.

So....how did you get Firekat to work, then?

I'll update the page with links, etc. today. The Dev, Mega, makes a Verizon Dev edition specific version of Firekat. 11x is the most recent and it is listed under the T-Mobile Note 4 section but labeled as vzw.

Help from experienced Developers!

Hello devs,
I have had a Micromax Canvas 2 Colors phone since a year and a half now. Custom/Themed ROMs were uncharted territory for me till June of this year, when my warranty was about to expire. I decided to use the VionicL ROM then. One heck of a ROM that was. Later, in the span of months, so many developments came in for the device, CM11, CM12/12.1, MIUI, and so on. I was very happy to see that there are so many people working hard on providing us the very best experience on our phone. But, like most of the average mobile phone users, I used to download the ROM, install it and enjoy, nothing more than that.
Now, as the time has come for me to switch to a new phone, I am switching to Lenovo K3 Note. I have had digitizer issues with my Canvas 2 Colors and the battery back-up was a little on the poorer side. So, I'm finally giving my phone away to one of my friends and moving on. Although, I would've loved to experience the final, stable build of CM12.1. Thanks to all the devs that worked hard on that. @Al3XKOoL : Especially you, man!
Now that I'm going to be using a new phone, starting from the 28th of October as per Flipkart, I looked up the phone on xda. Unfortunately, there is no forum for the phone. I was a little disappointed, but even C2C did not have a forum a few months ago. So, I tried looking for ROMs, and I have to say, I was a little disappointed with the progress in new and variety of ROMs. I agree that it is a fairly new phone, but there are a lot of people who own that phone, so I was expecting better results. And another point that many people like me would be searching for ROMs.
The help I request from all the developers here is to teach me to develop ROMs and Porting ROMs. I am absolutely inexperienced here, but I'm eager to learn. I'm 17 years old and I am studying 12th grade at the moment. I would still love to learn about ROM development and Porting so that I can provide the people with some ROMs like you all have. Although, I will not be helping out the C2C family, I can start to help the K3 Note family in any way I can. I hope some developers are interested in having an acquaintance.
Please consider this a sincere request and if anyone can please help me learn, I would be very, very grateful to you. I know that I can't learn it overnight, and that is why I want a proper guidance.
If anyone is interested to help me learn about the things mentioned above, please contact me through a message.
Thank you and sorry for annoying you lot with a long post!
And I will be indebted forever to all the developers in the C2C community for giving me and all the C2C owners a pleasurable experience. Thank You!
Sorry for tagging you people, but I hope you don't mind and you people are the most recognized devs in the C2C community :

first of all thanks for our words..im still using my WIKO RAINBOW as my second phone..ive moved on to VODAFONE SMART ULTRA 6 and im testing MIUI 7 LOLLIPOP with a ported rom already that is booting and running with TWRP ..although is very buggy its ALPHA version still, that is nice..
for developers/porters whatever is not easy to teach someone..we have our work to do and that kind of knowledge we have, it took us a few years and at least some dead phones, hard bricks and a few other bad things that could happen to our phone..so my advice to you:
read
search
talk with other users
now and then ask for help when you need it, some users know a lot
you need time and patient..be aware that many times things will not go as you expect or wish..best of luck and keep following us in my blog and youtube..RAINBOW / MMX A120 C2C still is a good phone.:good:

Is anyone developing cm 12 for lenovo k3 note

Hey, thanks for taking time out to read my post and replying.
Nice to hear that you've been working on a different phone and rolling out new ROMs for that phone too!
Yes, I know that everyone have their own work, family and personal stuff and everyone are developing in their free time or as a hobby. I will be doing the same too as I have my studies as a bigger priority.
I understand it is not easy to teach anyone about developing, at least guiding is possible, right? I would be glad if you could guide me in what to read and where to be careful etc. stuff like that.
I already bricked my K3 note once and revived it somehow. I know it will not be an easy road or it is just as easy as downloading a ROM and flashing it in recovery, most of the users can do that. I know it is hard work, I will try to read, but there is so much knowledge on XDA alone that it will take me forever to read, understand and be able to implement. So, what I am asking is, if you could let me know on where to begin and in which direction to go after that, I would be indebted to you.
Again, Thank you for taking some time out, I know you have loads of work, and I hope I can be as good a developer as you someday!

There is a Chinese developer who has rolled out CM12.1, but the English translations are not complete, so there are some chinese fonts still left behind, and there are some bugs in that too. I would not recommend using that ROM for daily use till the bugs are sorted out and the full English support is included.
With some support, I was planning on compiling CM12.1 for the K3 note. I've noticed that major developments for this phone is on some Spanish and Russian websites and not on XDA. I was a little sad to see that, but hopefully, there are a lot of developments on XDA too!

SM-S820L Lollipop Update?

Is there any way to get Android Lollipop on the Galaxy Core Prime SM-S820L? I have read about custom ROM's but I still don't know much about them and can't find any for this model. If anyone has found or created a way to flash a custom ROM onto this device, please let me know.

I also own this device, and unfortunately there is very limited support in the custom Rom department. If there was to be a lollipop Rom, someone would either have to port one somehow, or build it from source. Given the development rate for this device, I don't predict it happening anytime soon, sorry to say.

not going to happen
i have been trying since february the answer i got from my carier was samsung is contracted not to support this device thats why that is so hard to find samsung told me to take the device to bestbuy to force update if they could probably irrelavent but maby it helps

SM-S820L Got the Shaft!
Yup! This seems to be the future for the SM-S820L, or lack of future I should say.
I too have the Samsung Galaxy Core Prime SM-S820L. I have spent lots of hours scouring the internet looking through every android related forum in hopes of eventually finding someone that is undertaking much needed programming to build a custom ROM for this CorePrime version.
If you are looking for a custom recovery to use. I can point you to my and others posts over at Needrom. The best I can offer is an unofficial TWRP release, but it DOES work! It does for myself at least and I am no Android Guru whatsoever.
I guess I am not allowed to post Links in any of my posts yet because I am still a NOOB on these forums. I'll PM you with some direction my friend!
I cannot take credit for coming up with any of that software. I simply rooted around long enough to compile a collection of tools and files that worked for me to modify the Recovery of my SM-S820L.
:good: Feel free to shoot me a Private Message on this site or to my personal Email....... [email protected]
I would love to help out as much as I can with modding your phone. Like I said, I'm not a proffesional but I have read up on the procedures used and been successful with my own Galaxy Core Prime:laugh:
