We're having a device custom made and we wish to have a different system than that of an Android.
So we're investigating into the option of Custom-ROM and Liked AOKP.
Problem is, this isn't a device that can be listed, we're building the hardware ourselves.
Can someone point the direction of correct instructions on creating custom-ROM for custom Tablet?

Shimon3,
That can be a daunting project. A couple of quick questions:
Do you have all the vendor firmware for all of the parts? That would be really important. It would be best to have all the "device trees" "kernel source" and "vendor blobs".
Do you have the option to have an Android build made for it? If you can, and then get all the source from that, it would make building a second system, such as AOKP easier. If the company that is making the tablet can also put Android on it, and give you the source, then you could perhaps get someone to help you turn that source into AOKP.
As for how to build AOKP itself:
http://forum.xda-developers.com/gal...uide-step-step-instructions-building-t3402637
That is a tutorial I wrote for the Samsung Galaxy S4, T-mobile variant. However, all of the "device trees" "kernel source" and "vendor blobs" were available to build that.
I hope that sheds some light on the subject! Good luck!

I'm not understanding how kernels and ROMs connect. Can someone give me some extra insight?
[Hardware] <-- Unique to every phone
--
[Kernel] <--- Tells the OS how to talk to the hardware
--
[ROM] <--- Slightly confused. Is the OS in the Read only Memory, or has this term changed its "street" meaning?
I understand that most ROMs (e.g. CM7 and CM9) include both the kernel and the ROM, but can you flash these separately too?
I have a 1.5 year old thunderbolt that's rooted, and has CM7 which is based on gingerbread. I believe HTC has also released the kernel as open source, which is probably the reason I have CM7
Anyway, I guess what I'm looking for is an answer/guide/forum that explains why I can't install newer versions of android onto the already working/open source kernel I'm already running. Is it accurate to view the kernel as all the phone's drivers, or just the CPU driver? If that statement is true, why can't I load ICS or Jelly Bean onto my already existing set of drivers?
I'm thinking about starting a Wiki on this if 1) it doesn't already exist, and 2) I can wrap my brain around it enough to share with others!
Thanks to anyone with a response!

You are correct about the ROM, but ROMs also include the kernel (if it didn't, or no kernel was flashed separately, the device would not boot). Yes, other kernels can be flashed on your existing ROM, but it's not necessarily going to be compatible.
Sort of, but there's a lot more than that. See here and here. Later versions of Android will require newer drivers,etc. which the existing kernel won't provide (they'll be outdated). Back porting and additional coding is theoretically possible, but insanely difficult (many times). Even after this some things may still not work.
Thanks for the insight, I was able to get a lot deeper into this with those links. For anyone else wandering down a similar path, you might as well stop now! Here are a few links:

http://www.cs.uwc.ac.za/~mmotlhabi/avmk.pdf
http://www.iteachandroid.com/2012/01/what-is-firmware-rom-and-firmware.html
So, if anyone else is still listening, I do have two more questions:
Do any phones have truly open source drivers? (a.k.a. higher probability of allowing old hardware to work with new android OS)
Is there any way to determine which phones will be supported by the custom-ROM community early on? I know the Nexus line doesn't have vendor modified code, is that the direction which would have the highest probability to stay at top of the Custom ROM curve without upgrading devices every year?
Thanks again for any insight! I hope I'm posting this in a Newb-Friendly forum!

For both your questions, the Nexus-line devices would be the way to go. They usually have everything working on new Android versions the soonest, and Google always releases their code, etc.
Hi
i can use linux kernel (zimage) to update android kernel if yes ,how ?
thnx
I know it's not as simple as it looks, otherwise everybody could do it, but at least can someone point me in a vague direction?
Just out of interest, how do you upgrade a device tree to support newer Android versions? Anything in particular which might prevent Android from functioning correctly?
I've acknowledged SELinux as a problem already.
I'm new to running device trees and kernels but I do know my way around Linux (I know how toolchains works, and I can build Android and kernels, for example) and I know C++, C and Java.
I've 'Google-d' the matter, but to no avail – there appears no clear way to do it.

Hello!
I'd like to build my own rom from AOSP 8.0 official branch. I'm looking for some kind of guide but couldn't find any So, let's say I've got android source code and files from other custom rom that makes camera work. What have I to do to make my rom now? How can I build it and be sure that everything will work. Generally my target is to install android 8 on my Leeco le 2 x620 device with Mediatek chip
Any help is appreciated ^v^

"I'd like to build my own rom from AOSP"
So you mean an aftermarket os like lineageos or carbonrom or do you mean that you take the aosp repo and compile aosp for your device? You can look in source.android.com
"source code and files from other custom rom that makes camera work"
Is that an already compiled rom? Because you won't get source code out of that
"How can I build it and be sure that everything will work"
Ya don't. Nothing can ever be 100% bugfree, it can either be from your device tree's source code, or the aosp code itself.
Generally, if there is a caf tree for your device, it's going to be 3x as hard to create an aosp tree.
It is going to be 100000x as hard to create an aosp tree that is for a newly released, new hardware requirement operating system.
Wanna know the topping of the cake? Mediatek is notorious when it comes to releasing the source (in fact, it has become a meme in the Mediatek users world) but don't let that stop you son.
You can try, but don't give up just because it won't compile the first couple of hundred times. The errors when compiling should give you a great start
Good luck.

Oh God, how am I meant to do this ;0 There is Lineage 14.1 project on my device. I really want to have android 8 on my phone. Thank you for all the advice.
Yes im trying the same andere without any succes so far.
Im also trying to port from a different device ROM to the stock ROM what im running now.
The chip sets are the same but the Android versions not.
It would be really Nice if some mtk ROM developer find some time in his busy life to create a ROM for our phone.
Or a guide to compile/port Android o tot oud phone.
hi peeps. thank u for stopping by
i want to get into android development and make personal touches and changes to my phone. i quite like oxygenOS so i would like to stick with this and modify that slowly. but i cant figure out how to begin specifically with oxygenos? it doesnt appear as if they release their source code anymore. could anyone please point me in the right direction? thank you

Hi,
First of all, OnePlus do release their source code. But if you want to modify your phone and keep OxygenOS, you don't look it the right place.
With root you can have a lot more possibilities for customization, so I'll advice you to check Magisk (a root manager/ customization tool with which you can install modules).
If you want to theme your device you can use Substratum, and install themes from the Play Store.
Search about them and give them a try if you want to

thank u for getting back to me! i took a look at their github page but it said they stopped releasing the source code because it can be found elsewhere, and i cant find where exactly that is. i dont want to modify the OS as is (root it and customise that way), i mean getting the source code, changing, removing and adding things and then flash my own custom flavour of oxygenOS onto my phone. i figure going with what comes with my phone is best when getting into android development so that there are as few compatibility issues as possible. would you be able to point me exactly how i might obtain the source code? it would be very cool my dude

Check under the Android section on that page. Which specific OnePlus device do you have? There are many of them. I can help you find it if I know your model.

i see where you mean. but it seems like they stopped doing these releases. on their latest release (11 months ago) they said; "based on conversations we had with our dev community and the fact that we have only made few changes on AOSP(Qualcomm BSP) device tree, we will not be releasing AOSP device trees for future devices, the community can get the baseline from our device and get the source code from Qualcomm."
"the community can get the baseline from our device and get the source code from Qualcomm." i have no idea where to get what they are talking about.

They're probably referring to CAF sources for the Qualcomm bit. The baseline part is probably a reference to the script that's in the Android section. This is the closest thing to what you're after that I can find.

ah yes. my brain has clicked with the baseline part, i would plug my phone in and it would use adb to extract the "baseline"? i understand this process. is what i am asking for difficult? perhaps i am better off taking the kernal files for my phone and integrating it with stock android that i would build and practicing with that? i really appreciate your effort but this "android blobs" is apparantly for reference only, i have no idea what android blobs is. i went into this knowing oneplus isnt extremely AOSP friendly compared to Sony for example, but i am going to push on. do you have any advice? this doesnt appear to be a friendly introduction into existing OS modification by sticking with OxygenOS
Hello all, where would I start in making a working twrp for this phone?
Does anyone know if Motorola has released the device tree/source code for this phone so we can make the roms? LineageOS would be ideal.
Well, I have the same phone. Couldn't find ROMs for it.

look in this forum here, there are a couple floating around for it, I've made one, that I was able to fully flash to mine and has touch (Android 10. there's another that is 11 on here too by another poster), but as there are multiple display options out there it seems for how they were made, that is the sticking point, as not all will behave properly when booted into a recovery like mode it seems. I have tried installing it over bootloader and it will have touch then, but when flashed to recovery the touch never activates properly. So it all likely comes to that, as we'll need combine them in, properly applying proper checks for each display type and having it use the proper driver files, since can't load them all at once or it breaks things.

UPDATE: I have a telegram account where we are discussing how to make a custom lineage OS. I'm at the gathering stage and in the process of porting a device tree. For starters I want to start with lineage OS 18 because its the same android version the stock OS is, to be on the safe side, and that I've never done ROMS before.

Does anyone have a complete list of sources so far? I have some experience in the past building ROMs for Android 5 and I wouldn't mind trying. I have a lot of computer resources to dedicate to building as well.

Does anyone know if there is a kernel source? I looked on the Moto github and couldn't find one. Is everyone using prebuilt for the time being? Also, do we need a vendor tree?
Thanks
