Porting Questions - Android Q&A, Help & Troubleshooting

I can already guess the answer, but I still have to ask to be certain.
I have an A7 (2016) and I really need to port Android 9.0 Pie to it. I need a proper mostly stock rom. (basically a manufacturer rom) I haven't been able to find a phone that uses the same chipset (I doubt it exists)
Below two phones do not have the same chipset, but I am hoping they are similar enough for it to work:

https://www.phonemore.com/specs/samsung/galaxy-j7-core/sm-j701fds/
My question is, would it be possible to port from a different chipset if they are similar enough? Is there a way?
Thank you all.

Req. Unified Teclast/Mtk(Mediatek) chipset support? TWRP/CWM?

Hello All
Just asking around, wondering if there is a unified thread or devs working with MTK socs, or Teclast based devices. I am aware of Riley Rom, and that a lot of the dev may be Asian or Chinese based from the Baidu released with Teclast based firmware/ROM.
I have a Teclast P98 4g (A8H6), I've been able to root, but trying to install a custom based ROM or CM or AOSP rom..... first I would need to get a functioning TWRP/CM recovery to work on this device.... let alone drivers for adb....which I am able to get the tablet into adb. It's just been a headache reading through all these different sites and forums for other devices, trying to find a way and tools to get it to work for my device.
I see some support for Cube T7 and T9, and Teclast T98 4g (which is almost the same exact device, different camera and clock speed) and some other similar devices with a similar SoC/chipset as this one. Just wondering if there are eyes or ears anywhere that may have more information or a dedicated thread. I've come across some German Dev sites, for Cube T9, but wondering if any know Devs here in XDA or other links with similar work that we may be able to reference.
I've also commented on this one link for the Review of my device but seems there isnt much feedback there.... not a dev thread.
link: http://forum.xda-developers.com/android/general/teclast-p98-4g-updated-mtk8752-octa-t3065247
Req. Dedicated Mtk/Teclast Threads/Subforum ..... maybe possible to centralize all the info based on these Tablets , phones and chipsets and have a unified dev or tool set....
Updated thread for SP Flashtool or other similar tools for flashing/root....
to Admin and Dev..... not trying to spam or request anything otherworldly. Just asking the forum for tips, pointers.... maybe someone has answers or solutions I am looking for.... please move to where appropriate.

[Q] Dearth of Custom ROMs for Samsung Galaxy Note 5(Exynos variety)

Hi,
This is my first post on XDA, so please let me know if I violated any rules of this forum.
I have observed that there is a dearth of custom ROMs for Samsung devices with Exynos chipsets in general. Since the manufacturer doesn't provide much support/update after ~2 years, i think it there should be a way to increase the life of the device.
As an example, I have a Samsung Galaxy Note 5 (SM N920G) running Android Nougat and i couldn't find any ROM with Android Oreo supporting this device.
I have no knowledge of Android ROM development, so please forgive me if my questions are stupid or too basic.
1. How difficult is it to create a custom ROM in general and does Samsung make it difficult for developers by not releasing the kernel sources?
2. If the devices share a common chipset, how difficult is it to port the custom ROM to make it work for another device? Ex: If there is a custom ROM working for Samsung Galaxy S6, how much work does it require to make it work for Galaxy Note 5 as well?
I was desperate to try Android Oreo on my device and i have some time to burn this weekend. So i was wondering if i could try and create a custom ROM for myself.
I've also searched XDA and found some guides which were written for Marshmallow/Nougat. I am not sure if the same methods can work for Android Oreo as well.
I am looking for any inputs/suggestions and any sources you could point me to in my attempt to learn.

Asking for a 'light' / advice to more experienced devs (making AOSP + device to buy)

Hi, I'm in need of some advice about Android development/device to purchase,
Since the devs here are far more experienced than me I would ask some advice,
I started recently 'making' my own AOSP but I needed slow down after discovering I need to have the binaries(kind of: the drivers of the hardware?). So I spent my last 2 days searching about it and devices I could use
I came to the following understanding, I need the AOSP + kernel(as long as I have the kernel I don't need worry about the binaries from the vendor ? since the kernel takes care of it)
I'm thinking between a Moto C Plus or Xiaomi Redmi 6A, since I discovered there are currently ROM's and both have their TWRP. On the case of Xiaomi even the kernel is available. I also noticed the Xperia are good for development, but my problem is the budget I have available
Any piece of advice is welcome, thanks :good:

Hi there,
The best phone that I recommend is the Moto phones as they are easier to port custom versions of android. However, since the Moto C Plus has a MediaTek Processor, I suggest you look for other versions of the Moto Series phones that has a Snapdragon Processors. For example like the Moto E 2nd Gen LTE version, though it has a 1gb ram, I've seen many developers developing their own custom ROM.
I played around with MediaTek Processors the one thing I really don't love about them is that they are not robust like other processors. I had a Lenovo S820 with a MediaTek processor, the one thing I find annoying is that the MediaTek Processors use SPFLASH Tool.
But hey it's your choice like, just make sure the phone that you choose is able to port your custom ROM easily and won't brick the device.
Thank You

Looking for ROM for X96s w/ S905Y

Hi,
I am looking for custom ROMs for my Pendoo X96s which seems to have a X905Y SoC. I looked around and haven't really been able to find anything.
If one doesn't exist, I was wondering if there are any instructions as to ROM hacking for this chipset? I have some, albiet, outdated experience with ROM hacking for much older android phones, but haven't really tried that with Android sticks or boxes.
Thanks
AM
look here may be it will help you:

I've successfully rooted my Leagoo T5c, now what?

Hi everyone,
After a few hiccups, I successfully rooted my Leagoo T5c, thanks to the excellent tutorial posted here. The phone works fine, thank you, but now, I'd like to know how to proceed to, say, upgrade the phone from its current Android version (7.0) to a more recent version.
Where to start?
Since this phone has a Spreadtrum/Unisoc SC9853i SoC (Intel-based), I suppose the custom ROMs and upgrade possibilities are few and far between, but I'd like to give it a shot.
I'm open to ideas, tips, tricks, voodoo moves and Santeria incantations, but I'm still a noob when it comes to Android, so please, be patient, and methodical... :good:
@UglyStuff
If you can unlock phone's boot-loader then you should be able to flash any Custom Recovery and/or Custom ROM that's suitable to 100% to phone's CPU-architecture. Who is the supplier of phone's SoC isn't of any interest at all.
Hi,
Thing is, as I said, I'm a noob when it comes to Android, so I don't want to brick my phone by trying to make it ingest a ROM that's not suitable for it.
If my phone came with a MediaTek or Qualcomm SoC, I wouldn't worry, because there are plenty of ROMs out there, custom or not, to play with, but this Spreadtrum/Unisoc SoC is a thing of its own.
It's based on Intel's Airmont architecture, and few phones or tablets use it, at least this specific version (SC9853i). Maybe I just don't understand too well how a ROM is built.

For example, I found this article where they explain how to flash LineageOS 17 (based on Android 10) on a Panasonic Eluga Ray 800 that uses the same SoC as my Leagoo T5c.
The thing is, I don't know if this is transposable to my device, though the two share the same SoC. As I said earlier, I don't want to permanently brick my phone...
@UglyStuff
The mentioned Intel Airmount SoC's instruction set architecture is x86_64 , the also mentioned Intel Spreadtrum SC9853i SoC's instruction set architecture is x86_64, too. Hence in order to upgrade yor phone's Android you need a Custom ROM compiled for x86_64 architecture. GIYF ...
OK, but since this Panasonic and my Leagoo share the same SoC, they also share the same x64 instruction set, so do I get it right if I say that the custom ROM built for the Panasonic would fit on my Leagoo, or am I missing something?
In theory it should.
OK, I guess I'll have to chance it, and use recovery in case things so south. My phone isn't compatible with Treble, according to this app. Does it mean anything in terms of installing one of the generic system images found here or not?
