Welcome to YumiOS Rom For Galaxy J7 2017
ONLY FOR J730X

YumiOS - the revolutionary OS that maximums your phone's performance to a new level.


Some information you should know...
  • This is a super lite Samsung OneUI stock with android version 9.0
  • If you want to report a Bug, read the F.A.Q First Then provide a logCat OR LoggingKit.zip with detailed explanation
  • Read the instructions and the F.A.Q Before installing the rom or posting a reply.

This isn't a ROM, this is revolution.

RULES OF POSTING : READ everything before commenting, And especially the instlal steps, the rom has been tested throughly for a long time, so if you have an critical issue like not booting or no sim, you missed the instructions, posts that are irrelevant to this project will be ignored(Constructive criticism is welcomed). If you do face a new bug however, dont just say "hey bug here" provide more information, and a LOGCAT, bug reports without logcats will most likely be ignored.

WARNING:
YumiOS is very small in size (around 700MB). In order to take the size down to that level, I had removed/replaced many features (because YumiOS is designed for gaming and performance):
  • WifiDirect
  • NFC
  • Samsung Apps (except some system apps) and some had been replaced by AOSP alternatives
  • GoogleTTS and much more except GMS/PlayStore/Chrome
  • DeviceCare and Accessibility menu
  • CSC is very stripped down


  1. ensure you have LATEST TWRP from Here
  2. Download and copy the ROM to your device external SDcard (preferred)
  3. Wipe everything (SYSTEM,DATA,CACHE,DALVIK and preferably Internal storage all together)
  4. Flash the ROM.ZIP
  5. Do not flash another kernel/Magisk until a successful boot, else it will give problems
  6. Setup your rom and READ the F.A.Q for more information.
  7. To use another kernel (Cronos/Kraken), Flash it AFTER a successful boot


  • Nowhere to check battery status/storage (because DeviceCare is removed). Use another app in PlayStore
  • No Accessibility menu, apps that requires drawing on other apps perm may fail


IF you helped in this rom and i forgot you, tell me in a PM or in a reply
@soulr344 for always working with me on my projects
@I remember @Azsuperbored for ideas
@topjohnwu for magisk

Good idea to read this F.A.Q While the rom is installing

NOTES :

Q : I get black screen on boot
A : YumiOS has no boot animation, so that it boots faster.

Q : Rom is laggy, optimizes dalvik cache every reboots
A : Due to a ramdisk problem on custom kernels, you have to use stock kernel on first boot and after wiping dalvik cache. You can flash other kernel/Magisk on next boots

Q : Can i use front flashlight in 3rd party apps ?
A : No, Samsung restricted front Flashlight API to stock camera since Android 8.0. And since YumiOS has FootejCamera, front flash wont work

Q : I'm getting strange options in Settings app
A : Related to CSC, it was very stripped down in this build, will be fixed later

Q : What bootloader and modem do i need ?
A : Latest Pie Bootloader

Q : How do i know what Bootloader i have ?
A : Samsung info App

Q : How do i Update my Bootloader and modem ?
A : Flash latest Pie stock rom

Q : What to do after the rom is setup ?
A: Enjoy the brand new performance ;)
