[GUIDE]How to make a custom rom

---

Hey guys
i made this guide for new users that want to learn something about android development and make their own custom rom
*NOTE:this guide is made for new users, and here u will only learn how to mod custom rom not how to build it from source

Things u need are:

• "7zip" or "winrar" or "winzip"
• base rom
• patience
• notepad
• and signer (get it here)

Things u see when extract rom:

1.META-INF
2.system
3.boot.img

U wont need to touch "META-INF" and "boot.img" so open "system" folder.
There u see many folders (and build.prop) but since this is guide for new users we gonna rely only on this folders:

• app
• fonts
• framework
• media
• some other folders if u want to use scripts ˙(gonna teach u how just continue reading xD)

Now go to "app" folder
there u see many applications and maybe .odex files
here choose what u want to delete (*NOTE- if u delete application u should delete .odex file)
here is list which apps u can delete
*NOTE-make sure that if u deleted launcher that u replace it with your desired launcher

If u want to change fonts, framework and theme system ui then go to uot kitchen .U will just have to copy and replace files

build.prop
this is where u can change your roms name and add some tweaks

to change roms name u have to change this line
ro.modversion="here write your roms name"

*NOTE-without "" xD
here are some tweaks for build.prop tweaks
just copy<paste them

Scripts

to use scripts like Adrenaline™ Engine | 3.0 | or SlaidyBoost-V2.3
u just have to copy files from folders to the same folder
example for slaidy boost:
when u extract it u will see:
META-INF *folder
system *folder

navigate to "system"
and copy files from "etc" to "etc" rom
*NOTE- copy just files u see in folder not whole folder
and then copy files from "xbin" to xbin in your rom

1.Download base rom
-its best to take stock cyanogenmod that isnt already modded or some stock based
2.Extract rom with 7zip or winzip
3.Go to /./"rom"/system/app and delete apps u will replace or just delete
-its best to make rom as light as it can get (list of apps u can delete is given above)
4.Replacing bootanimation
-download bootanimation u want to use and rename it to "bootanimation"
-delete animation u find in /./"rom"/system/media and then paste bootanimation u downloaded
5.Adding scripts
-everything is explained in above post
6.Giving your rom name
-to change roms name u have to change this line in build.prop
ro.modversion="here write your roms name"
*NOTE-without "" xD
7.Adding build.prop tweaks
-explained in above post
8.Compress it in .zip
9.Sign it with signer given above

1. rename your unsigned zip file to "update.zip"

2. execute "sign.bat", wait for completion

3. "update-signed.zip" is your signed rom file

Koji unsigned file ?
