[Q&A] Porting ROMs

Good day everybody!
I created this thread here so that people cuold handle with this argument, Porting ROMs!
In particular I also wanted to ask help about a project I wanted to start by myself.
I'm new about porting full ROMs but I followed dozen of guides and got in touch with it!
I recently saw the new "Hydrogen OS" ROM for One Plus One and totally went in love with it! My project was to port this ROM to the Samsung S4.
Being my first time I'm not quite sure, so I wanted to know if someone could give me an hand or some tips!
Following guides I would like to port "Hydrogen OS" to my Samsung S4 i9505 using as base
ROM a version of CM12 5.0.2!
Is it possible? Will it boot or are they incompatible?
Can someone help me with This project?

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!

BlissRom for SM-T900

Hey everyone!
I have been blessed to recently get the Tab Pro 12.2 (SM-T900).. Amazing tablet!
I am on TeamBliss, and I am the dev for the great LG GProJ (rom & Official TWRP maintainer) & the Galaxy Note 10.1.. It took me a LONG time (and a lot of frustration) to get a perfect build of Bliss 5.1.1 for the Note 10.1, and before I get started on the 12.2, I wanted to see if the tablet is popular enough for me to post Bliss builds here.. I don't see many custom roms listed, so I wasn't sure if it was due to lack of devs or lack of users.. I would start with 5.1.1, and then try for 6.0 as it becomes more stable. I also enjoy adding features to the kernels, such as governors/schedulers and U/O Clocking.
Any input is appreciated!
Happy Holidays Everyone!

Would love to see BLISS ROM. I was hoping more devs would come over to build AOSP builds.
It looks like it is probably the only way we stand a chance to get Marshmallow on this device.

By all means, do it! I just finished up with finals, and was planning on seeing if I could figure out how to build marshmallow tomorrow haha. I was going to go from cm though. What is bliss rom?

Would love to see your ROM on my T900.

Go to www.BlissRoms.com, and you can see some stuff about us.. We've been around a while, and support a lot of devices..Bliss has tons of features..You can go to my two threads I listed in the first post and see lots of satisfied users.. Hopefully, I'll have a build listed tonight or tomorrow.

Would love to try this too. The 12.2 needs some love. Admittedly, Marshmallow is of greater interest though.

I have always wanted to try your rom! Please bring us Bliss lol.

Marshmallow on 12.2 would be so incredible.
Thank you so much for showing interest in the SMT900.

Yes please! Love my 12.2

lack of devs, not users. all new roms are welcome here. And will be appreciated

Yes! This beast of a tablet needs some Bliss. I am more than willing to test anything you would like to build for us.

Hey guys.. Sorry it's been a while since I posted.. So I've been working on a build in my free time, and I have a successful 5.1.1_r30 build I am testing now. I am an IT Admin full time, and have 6 year old son, so I don't have a lot of time, but I try to make time as much as I can.
I have updated the kernel from Linux 3.4.104 to 3.4.106, and added some governors and schedulers. I focused on governors specified for gaming, and a couple for battery/performance balance. I plan on getting the kernel updated to 3.4.110, but there are a ton of patches in between those versions. Over 700 if I remember right. I applied around 300 or more updating from 104 to 105 then 106.
I know we are up to 6.0 now, but since Bliss is still in the works for 6.0, I really wanted to get a stable 5.1 before moving on.
I will run the build overnight, and if all is good, I'll post tomorrow, so keep a lookout!

I'm glad I decided to take a look at this post can wait for BLISS on 12.2 SM-T900

I'm tagging along this thread waiting for an official release. I'm still stuck on 4.4 been waiting for something "newer" can't afford to loose root.

I'm sure if you bought her a t525 she would dev for you (It's harder for a developer to build blind with no device)

I'm not suggesting she do the firmware blindly, I only expressed sadness. And so there's no alternative ROMs....

I know how you feel, the t-900 had no roms either besides cm12 until wargear started building and I learned how to make roms from stock firmware pulls. many devs will help you in building if you pm them nicely for the guilds/tools they use.
since you have the device you could always try to do it yourself https://www.google.com/search?q=how...2&ie=UTF-8#q=how+to+build+android+from+source

I am definitely ready for this rom. Recently went back to stock for added functionality but I hate touchwiz.

@nerdyblonde
just wonedering if you are using kitkat or lollipop sources from samsung to compile (bc if you are on 5.1.1 firmware you have some lags running roms built on kitkat stock sources and need to downgrade firmware to eliminate lags)

Welcome to the forum! Bliss is indeed a solid rom and a nice addition here. Like a couple others here I've been banging away at getting past 6.0s hardware and processor problems took forever to get a solid 5.11 build and hoped 6.0 would carrythrough.... alas not to be! Working on Cm Slim and Liquid all have the same f2fs build error... any shared info would be appreciated and cheerfully reciprocated!

[Discussion] CM-14 for SM-T350?

Hello Devs,
I'm not nearly as experienced with Rom Developing as many others are, but I have a simple request,
Is there a Dev out there that would like to contribute to the Galaxy Tab A 8" and make a CM-14 based Rom for it?
The development for the SM-T350 has been slow, but successful, and I would really like for someone to point the spotlight onto this device and new ideas to be introduced.
Thanks for your contribution and keep the SM-T350 in mind!
Thanks,
 @vin_001

Kernel Source Zenfone 3 Zoom S

Hi Everyone,
We have a heck of a hardware and camera beast(Zenfone 3 Zoom S), but unfortunately we do not have a dedicated developer. Earlier i used to have a OPO and one developer @Sultanxda(hands joined in respect) used to built awesome camera roms, clarity which no other roms could match. I am a working individual with hobby of customizing phone roms through XDA. Hoping to learn cooking roms, but this will take time and I even dont know how far I can go. Anyways link to kernel sources for anybody brave enough for starting the challenge.
Kernel Source link :-

Thanks

Challange accepted.

Naman Bhai...
Pls develop AOSP or Lineage ROM for this device asap.

Surprisingly recent posts for the Zenfone.
I literally just ordered the Zen3zoom today as my travel phone (since I can't unlock my Note 9) and am actually super excited to get this phone!
I might try to learn how to make ROMs too....

guys, we do have developer who would like to prepare Lineage OS for this phone. if you're interested there dedicated thread titled "Search for developer". we need a few people to participate in cost of the phone so that the developer could buy one.
thank you
