What to do? Preparation before creating new ROM for Zopo ZP990+ (MT6592) - General Questions and Answers

So basically i got a little bit tired of being stuck with my good old Zopo ZP990+ and it's stock Android 4.2.2 and want to do something about it.
I dug a little bit through xda and other sites and found out that there are lots of official KitKat ROMs and custom Lollipops (Marshmallow even) for devices with the same processor (MT6592).
Some info about my model:
Zopo ZP990+ running slightly customed Android 4.2.2 with kernel 3.4.39. Got myself a TWRP so no problem with custom Recovery.
Wherever i go i see that in order to port ROMs i need to upgrade my kernel to 3.4.67 (or smth like that) so:
1. Do i really have to update kernel in order to flash custom 4.4.4 or higher? (Might be stupid question for some of you, but i just can't let go of hoping that it might run with 3.4.39 as well)
2. If i do have to then is there any way to know HOW can i update it? (Or mod it, whatever is fine with me as long as i will know how to do it or where to find info about it)
3. I also found a guide which shows how to create completely new CyanogenMod, so i was wandering whether i should go in that direction and then maybe just update that?
It seems like there is no official release of kernel source code (found something on github, but it's not official and i think it's for ZP990 not ZP990+).
Simply put i just want to ask about modding kernel, how to and what to do with it in order to get it working with better firmwares.
Thank You all for any kind of support given. If nothing is possible, then don't worry. I'll somehow deal with this harsh truth.

[Q] Roms compatible with Sharp FX plus? (ASD1)

Hello XDA,
I have bought a new android device for myself today, the Sharp FX Plus (Model: ADS1) and I've been browsing on the site to find some compatible roms; But no luck. I've used the forums before to successfully root and put a rom on my ASUS tablet with no issues, but this one is a mystery. Is there a thread with what roms are compatible with my phone or has nobody ever really looked into this phone? I've tried to google it with no luck, either. The phone is already rooted, I got that far, I just can't find any roms that are 'confirmed' compatible with it.
Thanks to whoever replies!
P.S. I'm slightly new to the whole custom rom thing - but I do somewhat understand the basics.
metoo!
I too have a sharp fx plus ads1. I have my phone rooted but am having no luck finding a custom rom. I understand it is kind of an entry level android and maybe out of date but it has all the capabilites I need. I also know enough to root my phone and install a rom but not good enough to actually create my own custom rom. Is there anyone that has the time and enjoys doing so that would help out with a custom rom for these phones? I found a page that mentioned updated to 3.2 with a new rom but there was no link for the rom so I'm thinkning it was a fake. Any help or suggestions would be appreciated.

EDIT: I posted in Misc Android Development section here, trying to put the information in a centralized area for any potential development on this device.
Recompiled the CM7 Kernel as a test using the device's config.gz, working on getting the CM7 source to go (its being tricky lol). I have a test CyanogenMod 6.1.2 ported from a Z71 that runs, as well as a modded stock 2.2.2 ROM. A "dirty-port" test of a Z71 CM7 rom boots with some mods (no radio, networking, etc..) - so there may be some hope for this lil thing!
Hope that helps

[Q] Device unsupported by custom rom. anyway to install?

I'm somewhat new to the whole idea of rooting an android device, and flashing custom roms. I've rooted my phone successfully, but there doesn't seem to be a custom rom tailored to my phone anywhere on the web. Is there any way I could use a custom rom (looking at CyanogenMod) for a different device on my own?
Any and all help is appreciated.

U can port ur own rom for ur device from the custom rom of a similar device with same specs if available with the help of dozens of tutorial in xda.
But you ll have to put a lot of hardwork on learning and implementing it, also have to sacrifice much of ur time. Indeed if you don't wanna do that, just wait until some devs to come up to cook rom for ur device if ur device model is new
Hit thanks rather than typing it

I think I'll take a look at some of the tutorials and give that a go. I aim to have as much control over my device as possible.

[Q] [Help] [New Device] I need help creating a ROM for my new phone

Hello everyone! I am a little new to this, so please take it easy on me. I have actually never created my own Android ROM via the AOSP, but I have opened up Zip files for ROMs other developers have created and have been able to do basics.
I recently bought this device: MPie G7 (gearbest . com/cell-phones/pp_76182.html)
As you can all tell, it is not exactly a very popular phone. So, finding source code for this phone's ROM is basically, impossible. I have also been unable to find the manufactures website address either (anyone have any ideas?).
Anyway, here are my very noob questions. I am obviously planning on hitting base with the AOSP code, but with Lollipop. This poses a new problem to me, because I cannot find the source code, how am I supposed ot create a kernel specific ROM? This thing runs on a MTK, most precisely: MTK6582. It came with Android 4.4.2 (KitKat).
I am also worried about one small other thing, which is the gestures. If my phone is on standby, screen is off, I can do gestures on the off screen to do certain things. Similar to the OnePlus One. But, I am worried I will not be able to do that if I build my own ROM from source.
Anyone have suggestions? Or can possibly help? Thank you very much. All your help is appreciated!

Why don't you list down some of the specifications of your phone and compare them with other mediatek devices!!!
That way if u have the stock ROM of the phone then u can port ROMs from another mediatek device like xolo q700i which has a dedicated thread!!! xolo q700i has many different number of ROMs !!! That way by zip based theming and porting you might be successful in at least creating a ROM for yourself which u can use as a base for different roms!!!
The way I see it if you don't have source or downloadable ROM from your OEM, you have two options:
- like @thecoolster said you could try flashing ROMs from similar devices, and hope you don't end up stuck with a soft brick.
- or, likely your device can be easily rooted (in the settings perhaps?) if it isn't already. Then you can make nandroid to give yourself a stock ROM to cook.
Actually porting your ROM from a developer device tree and AOSP or CM is hard if you are only a hobbyist cook.
Even with a cooked ROM, you'd need a recovery that lets you flash it or you'd have to use SP flashtool and make your own config files for the flash.

building a custom android ROM

Hello, I own an mtk device - Tecno boom j7-
Rooted, but running stock ROM ( android v4.4.2). 1gb of Ram and 16gb of Rom. It is a good device, however the manufacturers have refused to release an update for it. As it is not so popular, there are no forums for it or custom ROMs. I really want to upgrade my device to at least android 5.1, so I have decided to take matters into my own hands by "building" my own custom ROM (FROM AOSP), as I know that another device's ROM cannot be flashed for it (learned that the hard way ). However, I do not know how to go about getting and modifying the source code to work on my device. Since this is a device specific question, any tips or pieces of advice would be much welcome.
Thanks.

Building a custom ROM takes time and a lot of internet data.you're better of porting roms as there are a whole lot of ROMs for mediatek especially 6582/6592
I believe your phone is mediatek 6582 with kernel version 3.4.67 ,if so you can simply port ROM from sites like mtkroms and flash it on your phone
You're right about you can't flash another phones ROM (there are a few exceptions that are irrelevant here) ,but you can port( I,e make some ROMs that's are not for your phone but has the same soc and kernel version run on your phone)
There are a lot of guides about doing it
Good luck
P.s there are custom ROMs already available for your phone

Would there be any hope for getting Android Jellybean or KitKat on this old Samsung from 2012? (Samsung Galaxy Discover)

I have a Samsung Galaxy Discover, it's my old childhood phone and for the memories, I want to make it as usable as I can now, however I basically can't do anything internet related with it as it runs Android Ice Cream Sandwich (which I will be shortening to ICS for the rest of this post), ICS has certificate issues which you can't do anything about, to use anything internet related you need Jellybean (also has certificate issues but not as bad as ICS and they can be updated unlike ICS) or KitKat (has all modern certificates), however the Discover only has ICS ROMs, there was a Jellybean ROM at one point however the link is dead and I can't find an archive of it. I know it's possible to get Jellybean and KitKat on the Discover because the Galaxy Ace Plus has both Jellybean and KitKat ROMs, and the Ace Plus and Discover are basically the same phone, and I did spend a bit of time trying to port a CyanogenMod 10 ROM for the Ace Plus to the Discover, but I'm just too inexperienced with ROM porting and making ROMs and I had absolutely no idea what I was doing, so after I ran into an issue I couldn't find any details about on Google, I just gave up and went back to ICS.
If anyone could explain how to make a ROM (whether it be making my own ROM from scratch or porting an already existing ROM like CyanogenMod) for the Discover or even make a ROM for me, I'd be super thankful, preferably I want Jellybean as this is a super cheap phone and I don't think KitKat will run very well on it, however if KitKat is easier to get running I'll do KitKat. The exact model number of the phone is SGH-S730M. I have access to computers running macOS, Windows and Linux. (figured that'll be helpful to know if I need to make a ROM)
How do I create a custom rom?
Hey! So I was so happy with my phone, a Huawei mate 20 lite, that has been obsolete cuz it's old. I unlocked it's bootloader, and I will install TWRP for it, but there's no custom roms like pixel experience or Lineageos for it, so I decided to...

That page doesn't help. The first guide linked there requires you getting the device tree, vendor, and kernel from GitHub, and since the Discover is an obscure device, I highly doubt any of that stuff is on GitHub, I'd have to pull it from a pre-existing ICS ROM or something (but idk how to do that), and on the second page linked there I don't see any sort of guide.
