[Q] (Q) How to port roms? - General Questions and Answers

I have been looking at roms for my device for quite a while. Some are ports of s4 and xperia stock roms. How to port the latest version of android to my device? I read up on some guides and they all state that the port rom can be any working rom for my device and the base rom should be from any device which has a similar chipset. But there aren't many devices in the market with MTK6589 chipset and the existing ones don't have android 4.3. My question is , how did people manage to port the s4 stock rom to a mediate device. (the s4 has an exynos chipset). And how do people manage to port the latest android versions to their devices.
This may be a noob question but I searched through the forums and couldn't find anything much helpful.
PLS:I have some experience with Linux and its commands but don't know much of coding.

[Q] [Question] Requeriments to port a ROM?

I saw many posts about how to port a ROM. But in each post, there are many requeriments. My real question is to port, for example CM 10.1 for my phone that uses ICS 4.0.4 Stock ROM, but I don't know the real requeriments. In a post I read that it had to be the same manufacturer, for the drivers problem. Plus it said that must be the same resolution, the same Android version and the same processor or processor type. Can Anyone tell me wich are the real requeriments to port a ROM to my phone?.
P.D My phone uses ICS 4.0.4 odexed

Or can you tell me a similar rom...this phone is made in colombia..thanks
Hello,
Welcome to XDA.
If you want a custom ROM made for your device because there are none already available then you will have to ask around in the forums to find someone willing, they will have to have one of the devices to get he ROM working properly, you may have to donate a device for them to do. Or you could learn to Port ROMs for yourself or even learn to build a ROM from source if the source for your device is available.

Getting into rom development?

Hello everyone, I'd like to ask the following question(s).
Background: I've got experience in programming Java, C#, Python and I've messed around other programming languages before.
I'd like to get into the entire ROM building / compiling / 'cooking' scene but I am clueless as where I could start. I've a Zuk Z2(plus) with an unlocked bootloader and TWRP 3.1.0-3 installed.
Rom: AOSPExtended V4.4
Kernel: DarkMoon Experimental 178
Mod(s): shox_Audio_Mod V1.4
Gapps: Opengapps micro
Root: Magisk V13.2
I've been testing lots of roms recently, and now I am getting interested in (as mentioned above) compiling my own roms and maybe even port a rom myself? I'd start out with testing on my Zuk Z2(plus) since I can recover this device from any kind of software-brick. The main reason I'd like to mess around in this scene is because I've got an older tablet laying around with a MTK SOC, but with android 4.4.4 and I'd like to be able to update this
Tablet I'd like to upgrade (eventually): Cube T9 (currently only supports android 4.4.4)
I'd like to create a ROM based on one of these tablets: https://www.aliexpress.com/item/BOBARRY-10-inch-screen-for-T109-only-a-screen/32801822243.html
It might be completely fake hardware specs, I only hope that the SOC and the android version are correct (Maybe someone can confirm this for me)?
It's the only other tablet I've found running the MT8752 SOC and an android version higher then 4.x.x.
Any idea's tips or places where I could start best? I am open to all suggestions so please comment below

[Discussion] Touchwiz with android m 6.0.1 based on CM/LOS

Hello everyone !
As everyone knows that we have android 6.0.1 and 7.0.x available for Jflte devices i was wondering if maybe a jflte developer could build a rom that is TouchWiz
based on CM/LOS and have android 6.0.1/7.1.x like the rom we got earlier [MIUI 8 based on CM with android 6.0.1] by @mikussj3 .....
i don't know if it's possible to build it or port it that's why i started this thread
I hope i'm in the right section of the forum..
Thanks in advance
TouchWiz can't be based on Lineage.
And porting the TouchWiz stuff to Lineage requires a lot of work. Something that developers don't really want to do or don't have time to do it.
I may be wrong, but I haven't seen a single Lineage/CM ROM that has the TouchWiz framework.
And android 6, 7 TouchWiz ROMs can't be ported to jflte devices because ROM ports I believe have to come from a phone with similar processor type and architecture.
The only S4 that runs Android 6 TouchWiz ROMs is the klte (GT-I9506), which has a Snapdragon 800 processor. So it's similar to the S5, and that made ports possible or easier.

Guys it's not impossible to port android 6.0.1 TouchWiz to GS4 i9505 its just hard to do so. There will be a lot of code changes and stuff like that.

And even then, if some developer ports MM TW, it will be very buggy, and by the time the bugs got fixed, everybody will move on to newer devices.
Think about this way: if that would be possible, a port would already be done.

Porting an Android ROM of higher version to a device having lower Android Version

I'm having HTC Desire 626G+, Running DOT OS 1.1 (Android 7.1.2).
And i'm looking for Oreo (8.0) roms for my device or my chip set (MT6592).
But i'm unable to find one, so i'm going to port a rom for myself!
And i want to know one thing...
Are there any tutorials regarding porting Android of higher version (8.0) to a device having a lower Android version (7.1.2).
All I need is, does the normal 'porting' method applies for the above or not. If not, please suggest me a tutorial.
Thanks in advance!!!
