How to Develop Roms For LG GT540

As the topic says, i want to start developing or porting ROMs/Kernels
for the LG GT540 or any other phone.
I know a fair amount of computing and game developing. So can
anyone tell me what the requirements are for developing a simple ROM.
For example like how much RAM i need on my PC and need to learn Java c++ and etc.
I do know how to make an android app but couldn't put it in the market
as i need a license which i didn't buy. I don't know how to make 3d games
and stuff i can only make simple 2d apps.
I did read some stuff here:
http://developer.android.com/guide/index.html
http://source.android.com/source/initializing.html
and a lot more.
I know developing isn't easy but i do like technology and stuff like that,
so that is why i want to learn.
Thanks.

i think building ICS is a bit too advanced for me. Maybe requirements for
AOSP for building from CM sources?

It's good to have dual core processor and you must have more than 1GB ram (otherwise linux system will kill process, because he will don't have memory). And maybe 30 GB disk space.

Firstly you'll need C++ and Java. But that's not all. You'll need to understand the structure of the Android source and kernel and how they work. You need to know how to write your own device configs and makefiles. And you must know how to solve errors.
Your build machine should meet the requirements for building Android. On my machine, Gingerbread is ready for 2 hours. Here are my specs:
Intel Core i5 430M Dual-Core Processor 2,53GHz
4GB RAM
Ati Mobility Radeon HD 4570 512MB Graphics card
500GB HDD

I'm afraid I can't help, but I want to know!
I spent only 2 Weeks learning batch and html, so I'm quite clever. I'm currently trying to learn java, then will learn C++

i will try building Froyo as i think it will be easier and less system
requirements will be needed.
Also i am trying it make linux boot through a USB. will this be a disadvantage?
Or is installing linux as part of system better?

how did u learn it?
And how will u develop when u said u have no PC?

Maybe at school ;P

Also is ubuntu a good ISO to use?
i will be changing PC soon to a better one so i am
trying to install linux on my USB.
is it possible to create a ROM from the phone?
Like booting into linux and then doing what you would do
on the PC?

The better version is 10.10 , On the latest version (11.xx) Unity (new UI) is really big ****

Hehe, try to load your backup in emulator

The most important thing is to know how to make Device configuration files and makefiles. Can anybody explain? Plzzz!!!!

Lol similar specs!!! Just that mine is a i5 480M and has 1gb graphic memory
And no don't run from USB all settings wont be saved like wallpaper every boot resets everything

Is much simpler install ubuntu on hdd
if you build android on a usb you wil ran out of space
i want to learn too lol

I want to kill my phone so now dl'ing ubuntu and ICS sources.

How about installing on a virtual machine? It will may have lower performance (depending on settings) but installing on a hard drive isn't reversible.

WINDOWS,UBUNTU on Android

Guys I am gonna share with you some information about porting Windows and Ubuntu on Android.I've tried Ubuntu and it works on my mini.I've also tried windows XP but as our mini has less RAM and processor it doesnt successfully boot up.SO Iwill recommend you Windows 95.
For Ubuntu:
Go to this link:http://www.androlinux.com
Download the zip and follow the video tutorial given there.
It will utilize your 2GB of sd card.After installing Ubuntu go to terminal then cd to sd card/ubuntu and give the command bootubuntu.Note that Android will be running in background so ubuntu will act as a Guest OS.
For Windows 95:[I've not tried it but it is for all androids]
Go to this link: http://www.youtube.com/watch?v=JWkqMmtSJRE
Thanks to opensourcegangster on youtube for the video.
Also file size is not large.Hope it works on our small mini
Still if you want to get Windows XP on android then follow this link:http://www.youtube.com/watch?v=EUE-gJmcGKk&feature=relmfu

screenshot ?

i believe its requires atleast 1Ghz cpu...thats our mini doesnt have...yes,maybe you can install ubuntu by ubuntu installer or windows with qemu and boot,but battery and cpu are forcing to do it and of coz there is a risk.....CMIIW

I've rubbed off ubuntu from mini.Forgot to take screenshot.Dont suspect it,I had tested it on mini.

I think you haven't read my description clearly.Just go to the link in the last line of my first post.And also please don't post anything if you're not sure about it

that was chroot (not good to use it on 384ram)
i give u a clue, use non-chroot (it will run any unix with supported arm processor)
i use DSL as unix os (only 0.5gb) .
for windows, megh....! keep dreaming.
what the use for run win95 or 98, thats oldschooll OS, LMFAO!!!!

Lol it works

ROFL man, you make my day , if you are an average user you should know that windows xp can run on less specs devices; so the minimum hardware requirements are:
Pentium 233-megahertz (MHz) processor or faster (300 MHz is recommended)
At least 64 megabytes (MB) of RAM (128 MB is recommended)
therefore, if you're smart enough you can conclude that your statement quoted above are nonsense.(no offense here just my 50cent )

Android is built upon ARM architechture and also it's a MOBILE running XP.What do you want more than that?It is different from windows and also plz go to the link and see the video.I think you haven't.And also I had quoted that it requires more RAM and processor FOR AN ANDROID TO RUN WINDOWS.Windows 95 and ubuntu work on mini

Ubuntu is nice
But the windows 95 nahhhh

[ANNOUNCEMENT] Introducing Remix OS Player - Android Marshmallow emulator for PC

We’ve just released Remix OS Player, an Android Marshmallow emulator that lets you run Android games and apps directly on your Windows PC.
Download it here: www.jide.com/remixos-player, play with it and give us feedback here: http://bit.ly/2cxZhBs.
Check out the video intro here: https://www.youtube.com/watch?v=zLcCYmWTl-g
Remix OS Player is now the easiest way for you to experience Remix OS, especially if you still haven’t been able to get it working on your PC.
And, just like Remix OS for PC, it’s free.
Give us feedback and let’s build it together.

hopeful
i think it will be better than bluestacks and andy... tns jide team

Good to know you're getting into the android emu competition!
I've been testing several android emulators on my device, and I sue mostly MEMU as it is the fastest and most stable.
Still, having RemixOS as an emu on Windows 10 would be great. I made a few tests and here are my impression:
- not enough setting on the advanced tab before booting up. I'd like to assign more RAM and CPU cores, and most importantly, a higher resolution as my device has a 2160x1440 resolution.
- Performance is quite low, maybe it will be better if I can assign more resources.
- no full screen mode - this is essential for running it as a real emulator
- I can't find a way to share files and APKs from my windows partition as in other emulators
Looking forward for more updates

Can't boot. Stuck at loading screen. Not sure why. Or do I need to wait longer?
Surface Pro 3.
Edit: Never mind. I reinstalled and it works now.

This is what I get:
emulator: ERROR: x86_64 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: Unable to open HAXM device: ERROR_FILE_NOT_FOUND
Please help!

This is great. I've had Remix OS as a dual boot option on my Windows 8.1 laptop. But wanted something that I can quickly switch between Android and Windows, rather than reboot each time. Recently found LeapDroid and it perfectly fits my bill so far. I'm glad Remix is jumping on the VM direction as well. I'll check the OS player.
---------- Post added at 11:01 AM ---------- Previous post was at 10:42 AM ----------
Getting this error. Looks like VT-x needs to be turned on? I'll keep checking.
------------------------------------------------------------------------------------
emulator: ERROR: x86_64 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: VT feature disabled in BIOS/UEFI
---------------------------------------------------------------------------------------

Sadly the emulator isn't working for me. Starts loading up and then just closes without an error

Cursor issues
I installed the new Remix.exe and it appears to load fine but the cursor force moves to the left leaving me unable to click anything. Anyone else having issues? I am on a Lenovo 460s touchscreen model. I tried uninstalling and reinstalling but still having the same issue. Any help would be appreciated.

You need to install Intel HAXM

You need to install Intel HAXM. I had the same issue and resolved it by installing Intel HAXM. It basically reserves a particular amount of RAM from your PC for running Android x86 sources. I have linked it in my guide here, have a look: http://techbeasts.com/download-remix-os-player-for-pc/

for the ones who does have virtualisation error ,you need to go to tools and instal intel haxm app.
it is a intel android emulator runtime provided with remix player.
now my feedback....
this need a full screen mode for the app.
it need to save settings for resolution/cores/ram.
it need ota updates.
It need stable and working play store.
It need smoother zoom and scroll.
The key mapper need to be in app instead of in rom.
it need open gl es 3.0 support.
need 4cores 4gb ram support.
and this absolutely need game controller support!
it need large hdd image support.(8 16 32 64 gb)
outside this everything is ok.

Install Intel HAXM and try it again It will work.

Can someone direct how to get google-apps and root on this one? Thanks.

This is only for Intel CPU?

Can't be installed. Gives me error. Can't find driver or something. Saw in the comments on the download page many people have the same problem after Anniversary update... So messed up.

Huawei GPU version

Hi there People, I have a Huawei P9 L-09C432B378 (Nougat) and i would like to know a way to see our GPU version (Model I know that it is Mali-T880) but what I want to know it's the driver that this sofrware (B378) is using.
If someone could help me I would aprecciate a lot.
Thanks

Phones doesnt work exactly like PC, so there is no "driver" that you can update/check separately and there is no separate settings file that you can modify to mess with it a bit.
In terms of spec, P9 have mail t880 in Midgard architecture
its version MP4 that contain 4 cores clocked at 900Mhz in boost mode and it use simplified driver interface AMBA4 Ace-Lite, so it provide power depending on task with less data pushing though memory.
It also support almost all modern APIs:
OpenGL® ES 1.1, 1.2, 2.0, 3.0, 3.1, 3.2
Vulkan 1.0*
OpenCL™ 1.1, 1.2
DirectX® 11 FL11_2
RenderScript™
Click to expand...
Click to collapse
Basically there is no specific version number of drivers used in P9, its all in system it self, that is provided by huawei with android ROM.
You can mess with few settings for MSAA, video quality, but beside that nothing. Its GPU on SoC that is maxed out from the box, and only way to sped it up is upgrading chip it self to version MP8 or MP16, and of course its not possible :]

My question was all about this:
http://vulkan.gpuinfo.org/displayreport.php?id=1046 (this is a driver for 7.0 (Nougat) with a driver version 465.204.476)
http://vulkan.gpuinfo.org/displayreport.php?id=920 (This one it's another driver ALSO for 7.0 (Nougat), but with a diferente version number (511.1023.4095))
Which one of those it's the one in ou P9 L-09C432B378????
And there is another that came out today:
http://vulkan.gpuinfo.org/displayreport.php?id=1132 (this one it another one BUT it's for 7.1.1. (Nougat) with the same driver version number as the second one (511.1023.4095))
My question it's if is it possible to know which driver version number do we have on our P9 and if it's possible to install the latest driver version as a zip file just like the guy as the (P.S.)
http://vulkan.gpuinfo.org/displayreport.php?id=1132
P.S. My question was all because of this threat:
https://forum.xda-developers.com/crossdevice-dev/sony/mod-adreno-vulkan-drivers-snapdragon-t3555141
This guy made na flashable zip for their Sony Devices with Adreno 430 and 530 so they could install them and appreciate all the good things that vulkan can offer to them.
I think that this is a good subject for some question and an AWESOME answers.

ok.... so i just downloaded Hardware CapsViewer for Vulkan (apk) and It says that driver version it's the 465.204.476 so it's the first link that I shared.
So now I was wondering what device as the other one that as the other driver version, the 511.1023.4095 one? Cause for what i undestood, the 511.1023.4095 one it's allready autorized for 7.1.1 Nougat

There are march drivers, but you have to selfcompile it.

Windows 10 ARM on OnePlus 6/T

Maybe someone will be interested in running Windows 10 on OP6/T. I'm using it on my device... aaand it's not suitable for daily use, but it's pretty capable as of now.
Current status of the project:
- CPU works
- Touchscreen works
- USB works
- GPU partially works (there are some glitches, that's why driver isn't pushed yet to github)
- audio doesn't work
- wifi/bt doesn't work
- and pretty much everything else doesn't work
Thanks to https://github.com/edk2-porting for making it possible!
Tutorial to get it working is here: https://silime.github.io/2021/05/20/Windows10-on-arm64-EN/
I've recorded an video how it's done here:
Also I've tried some games on this thing, you can see results here:
NFS MW:
HoMM V:
Left 4 Dead 2:
But there is one important question... Can it run Crysis?
And answer is... Yes, it can:

Hey man, i'm thinking of installing windows 10/11 on my device "OP6" but have some question.
i saw your video of installing the OS, so when ever i want to boot-up windows i have to flash the "UEFI" image to boot-up windows ? cuz i saw some video about this , when rebooting the device normally through android or windows io reboot to android, but to boot-up windows they flash UEFI image through flashboot and it boot-up windows, right ? if so, when every i want windows i should use another PC to use windows on my mobile device

And can i use "EDK2 - v0.4.2" so that i can have wlan (wifi) support ? ( as the release say )

I noticed you haven't gotten a response.
The project is a lot more stable than it was (although still a long way to go). WiFi, Bluetooth and battery as well as a few other things have had support added since this post. I recommend joining the project's Telegram or Discord if you are interested in updates or need help with something..I don't know if I'm allowed to post the links here but it's not too hard to find
