Can someone develop a ROM for $$? - Android Q&A, Help & Troubleshooting

I've seen these chinese companies like Mi & Huawei selling cheap Android devices. They have been under scanners of private data leaks. I was thinking is it possible to get fully customized ROM with all google and manufacturer footprints removed with some additional features than other custom ROMs?

Few of the Xiaomi and Huawei devices have good custom ROM support. Try to search for device specific threads for details regarding flashing roms.

A bare operating system

Hello... Since I'm not very familiar with cell phones I'm curious about something. With a desktop computer, one can build their own or have a manufacturer type ( Dell, HP and so ) Now if you take the custom build system you basically can decide which OS you want, why can't cell phones be similar to that be able to install whichever OS you like, Or can you? Like in Android is it possible to install just a basic OS onto a phone? one that doesn't have let's say Google ( Google store)? Is there an Android build without Google? Also, does Android have an OS with its own browser, if not, why not? thanks

You're thinking about it along the correct route. There are plain, unbranded Android builds known as Vanilla Android. These are the builds you see on Nexus and Pixel devices, built from the AOSP (Android Open Source Project) and have no carrier or OEM bloat.
If you're looking for a lightweight Android OS with no GApps (Google Apps), there are a ton of custom Android builds available, the most popular in the world being LineageOS. However, it should be noted that you can't simply flash a vanilla or custom Android build to your device and expect it to boot and function properly. Android ROMs need to be ported to a specific device. This is due to the vast hardware differences between various manufacturers and models.
To see if any custom Android builds are available for your particular device, search your model device in the Search Plus option. If any custom ROMs, kernels, recoveries, etc., are available for your device, you'll find them here on XDA.

2. Most of the big brands have custom ROMs. Google, Sony, LG, OnePlus, Samsung, Huawei, etc. all have custom ROM support.

Security question about custom roms

Hello,im new at this forum und want to learn something.I've been using stock roms until recently.But ı recently started to install new custom roms on my phone and ı had an important question.How safe are these custom roms? Is there any possibility of stealing credit card informations or credentials with custom roms?If the answer is yes,how can we know if there is such a thing?(Stealing informations or credentials with custom rom)How can we understand the custom roms containing these types of software?I would be very happy if you could answer my question.
Thank you very much.
If I could understand you well, meaning the rom will be stealing your information. Your stock rom even steal your information which you are not aware. Depends on the apps running on your device. Google apps are number one. Other device brands also collect information from using their device which they claim is for statistical purposes, which the user is not aware. Every rom is not safe ones you are online.

[HELP] New "developer" in desperate need of guidance (ZTE Nubia NX629KJ)

Hello all!
First time Android "developer" Cory here. I've been rooting phones and flashing all kinds of things for years now, but this is the first time I actually want to try to develop something.
First a quick introduction about my community and device. The Nubia Red Magic 3 has been pushed by all sorts of online personalities and tech companies, even XDA. It's a Chinese gaming phone with tons of power, and the first ever mechanical cooling system. However ...it's global release has been staggered by very, very poor firmware. It runs on Android 9 and lacks many features that leave global (English) customers feeling ripped off in some way.
I want to develop a stable, stock-based ROM for my community by learning how to take the good bits of the Chinese version of our devices ROM, and merge it with the "Gapps" compatible variant that we all know (and hate).
I've done lots of research online, and so far have only found a tool that lets me extract system.new.dat.br so I can change things like sounds and graphics. I don't know how to repack it.
There are lots of Google results for things that seem helpful, but turn out to be very outdated, sometimes by as much as 7 years. Also many links to tools are either dead or outdated (even here on XDA).
We (the Red Magic community) are desperate for a stable ROM that we can use daily, and I want to deliver that. I have ideas of where I want to start, but I can't find out how.
Thanks in advance for any and all guidance!
-------
Current checklist of To Do's:
Change system sounds (done)
Create stable, Interactive based kernel
Fix Chinese system translations
Debloat proprietary Chinese apps for global users
Implement stable launcher/replace permanent Chinese launcher
Integrate system Gapps into ROM
More to come.

Making a ported ROM stable

Hi all!
So I have a weird question. I've got a device with a "global" ROM variant that falls short of the features offered to it's "native" market.
The Chinese variant of this devices ROM is feature rich and utilizes the devices hardware better than the poorly implemented "global" version.
Custom recovery, or TWRP, is available on my devices Chinese ROM, and the members of my community are installing Gapps ARM64 9.0 Pico overtop of it. But it's not the best it can be in terms of launcher support and network connectivity. Any suggestions? There are a lot of us that feel ripped off by our device's manufacturer, and would love your support!
