Introduction​
This video gives information about the basic tools for ROM development.
Tools will be uploaded once the tutorial is completed.And the links will be posted in 1st post.This tutorial is for all kinds of devices.No matter what your device is ... you can use this tutorial...
Though ftf files are only for Xperia devcies which are used in flashtool to flash stock ROMs to Xperia devices.If you have other device the don't get confused if you will not ftf file for your device.Try other sources to get system files.

Getting System Folder​
Universal method for obtaining system folder (Root needed)​This tutorial guides you how to extract system folder from .ftf packages and get system folder for your custom ROM easily.
For this we have used ftf extractor.
Though you can flash your device,install stock ROM root it and then copy all system file to SD Card and get the system folder.This is universal method and can be done easily using terminal emulator.
For this simply download Terminal Emulator from Android Market.
Install it on your freshly flashed device as stated above.
Open it and type:
su
This will give root permission to your terminal emulator.
Then type:
tar -c system/* >> sdcard/system.tar
This will copy all your /system folder to your SDcard with name System.tar
This will take some time to finish so be patient.
After it's done you should have a tar file in your /sdcard named system.tar
You can extract it using Winrar or 7zip software. But yes this will have huge size , as it has other useless folders so you will have to delete them. After extracting this system.tar file you will get following folders (Similar one)
Code:
/app
/bin
/etc
/fonts
/framework
/lib
[COLOR="Red"]/lost-found[/COLOR]
/media
[COLOR="Red"]/sd[/COLOR]
/semc
/usr
/xbin
build.prop
[COLOR="Red"]And some other files and folders like ""autorooted,kernel files" etc[/COLOR]
Now simply delete the folders marked in red color and its done.Don't worry if you don't have folders with red colors above,we don't need them.
And the final files that we will have in our system folders will be
Code:
/app
/bin
/etc
/fonts
/framework
/lib
/media
/semc
/usr
/xbin
build.prop
Now thats all...
Use this pre rooted ROM as your base now and have fun in tweaking and customizing .... Hope this is simplest method that you could ever find...

Very nice!!! This is the first time I have searched for Android ROM development and look what I find, the KING, of all Android ROM development posts! Thank you SO much for the time you have put in to this...

Very nice, will take a look at it for a nice refreshment.

Looks pretty good and detailed, nice guide.

How about finding another file host. I don't like being forced to download crap that I don't need.

That SK17i...ftf package is stock firmware for my Xperia Mini Pro.By opeing it i have extracted system.sin file.
You will need ftf package of stock firmware of your Galaxy3 as you mentioned in your signature.
Also re install cygwin Completely and add kitchen files in cygwin/home/<YourUserNameOf PC>/kitchen to remove that error.

Great!! Thank u!!!

Easy change boot logo(splash)

Download and extract attached file put it disk.
Into folder New_logo insert pic format png, size 800x480.
Run Start.bat and created file oemlogo.zip install into recovery.
The roms which have not liboeminfo.so library, such as Aurora use start_lib.bat

i tried and its really goood and easy:victory:.....rather than genokalar tool.

Where is created oemlogo.zip? After starting start_lib.bat I can not find this zip.

In the folder New_logo. Tested only on 32-bit Windows xp/7/8.
Do you have a 64-bit Windows?
EDIT:
Now I installed 64-bit Windows 8. Everything works.
I do not know where is the problem with you.

sysMapFile TWRP Error - Custom ROM

Hi guys!
Ok. so I'm (really) not a developer, I'm just trying to make a flashable ZIP (+ custom recovery and root) from the latest D80230f_00.kdz (told you, not a dev', but, yeah, everyone should starts with something right?). and I got some difficulties at the end of the process: when trying to flash the zip file, I got a big red error (ok, just red) in TWRP: "E: failed to sysMapFIle /sdcard/rom_name.zip".
Have you ever met this error?
Furthermore, I got a question about the update-binary file (maybe it's link to the error?): I've downloaded @somboons KK_template_new.zip, but their was already an update-binary file in it. I've unziped the archive, write everything I need in the updater-script, and re-zip all (see attachments), I don't do anything except ziped all: should I do something else such as sign the archive or thing like this? 'cause I don't find anything accurate about update-binary file: I don't know if we have to take it from other archive, or if it's create during signing the archive.
Oh, yeah, the recovery.img is TWRP 2.8.7.1.
Anyway, all kind of help will be very appreciate.
Thanks in advance guys !

@casual_kikoo
I would ask a mod to move your post to the Q&A where it belongs
I'm not sure if they move them or delete threads when they're not in the right sub forums.

Whenever u flash a zip for it needs to be signed, I would check or Ayysir's Android Kitchen, that's where I started my development from, I started just like u, only modifying touchwiz roms and repackaging them in flushable zoos format with android kitchen, if u need help let me know
P.S., Windows is NOT the platform to start development on lol, if I were u I'd start dual booting whatever machine ur using with a Linux OS of ur choice, for someone new like urself, I'd go with Ubuntu

First of all, thanks you so much for your fast answer. Yeah, I know Windows isn't the easiest platform to start development. Well, I've already have Ubuntu installed on VMWare, I just took screenshots on Windows .
Ok, so if I understood well, update-binary file is created during the signing step? That's why it doesn't work right now, 'cause I don't signed my ZIP.... Yeah ok I start to understand !
I'm gonna download Android Kitchen (this one right?) and start cooking !
Again, thanks you so much dude you make me more and more enthusiast about creating ROMs on Android.

Trying to install Wear 2.0 developer preview 3 on Huawei Watch

I'm trying to install Wear 2.0 Developer Preview 3 on Huawei Watch. I'm currently using Developer Preview 2, so I thought I'd be familiar with the flashing process.
Anyhow, all the tutorials I managed to find include a part with running a flash-all.bat, which for some reason isn't included in the preview image package I downloaded from https://developer.android.com/wear/...ampaign=android_discussion_wearpreview_092916 .
Where can I get the flash-all.bat?
Edit: Umm, I decided not to go with DP3 at least for now. I thought I'd return to the official stock firmware, but how do I perform the flashing? Do I manually have to edit the file names in flash-all.bat to match the file name of the stock rom's name? Does it matter that the stock rom came as a .tgz even though the files mentioned in the flash-all.bat are .img and .zip? Damn this is confusing, and googling isn't helping at all...

This page is what I'm using as a guide. Worked fine though did take a bit to get the flash-all.bat to run. All files are included in the downloads. Top download is preview image. Bottom is to go back to stock.
https://developer.android.com/wear/preview/downloads.html
Sent from my SM-G935F using XDA-Developers mobile app

The stock download from that page does not contain a flash-all.bat.

I used stock download for flashing and ewerything goes just fine. Just extract all packages in same folder. But if you are interested use this link http://rootjunkysdl.com/files/?dir=Huawei Watch/Firmware. There is all revisions.

The downloadable files there are .tgz and do not include any .bats or .zips (I tried opening with 7-Zip).

You have to extract .tgz file too. And all files has to be in same folder beore flashing.

Personally, I would be grateful if someone can provide me with the set of documents already downloaded and extracted; and, if I am not asking too much, to please give me a dumbman's procedure to get the Wear 2 software to work on my watch.
Having to now wait until early 2017 will surely drive me crazy!

Unroot & Re-pack firmware?

I had 50pc japan version of s5(sc-04f), installed rom 'G900F.STOCK.FOR.SCL23.FULL.MINHQUAN'. The downside of this rom is that its pre-rooted. I managed to unroot it by goin in supersu & click 'full-unroot'. But i had multiple devices to flash, so is there a way for me to re-pack this firmware again after i unroot it? So that i could flash it to my other devices without root.

Generally, if it's 6.0.1 and rooted systemlessly, you need to replace boot.img with a stock one and remove SuperSU app from system.img.
This ROM intended to be flashed from TWRP, so it's an ext4 image.
You can mount it to a linux system on your PC and remove anything you want.

I havent done anything like this before. Could u give me some links or guides? My PC is running Windows 10.

Ok, here' a simpler way:
1. Make changes on one phone.
2. Make a TWRP backup of boot and system partitions.
3. Restore this backup on other phones. They must have TWRP installed, a 6.0.1 bootloader and modem.
You'll have to rename backup's folder path and to wipe cache/data/system before restore.

can i use winrar to extract & compile the rom, without linux? So that i will have a much faster flashing process for all other units..

Ok, I've managed to download that ROM at last.
The things look even simpler.
To prepare an "unrooted" ROM:
1. Download the zip form this post and unpack updater-script somewhere.
2. Make a copy of V3.G900F.STOCK.FOR.SCL23.FULL.MINHQUAN.zip, open it with Windows Explorer and replace V3.G900F.STOCK.FOR.SCL23.FULL.MINHQUAN.zip\META-INF\com\google\android\updater-script with the file you've unpacked from the attachment.
3. Try to flash ans see if it's what you need.

thx so much, already passed all units to the buyer. ill try that on next batch restock, may iknow if there's a way to get the service menu shortcode *#0*# to work again? This rom doesn't has the service menu.
