About

Built for longevity.
Optimised for performance.

The Exynos 8890 is still capable hardware. EylemROM's goal is simple: take the latest One UI releases and make them run beautifully on the S7 and Note 7 family — no compromises, no cut-down features.

Performance
Kernel optimised

Custom HeroGrace kernel builds with CPU/GPU overclocking, undervolt/overvolt support, and F2FS data partition support.

Fidelity
True One UI ports

Real Samsung One UI — not AOSP with a skin on top. Galaxy AI, KernelSU Next support, and Aroma Installer for customisation.

Root
KernelSU Next

Every build ships with KernelSU Next V3.1.0 support and SELinux Enforcing, keeping security intact while allowing root access.

Supported Devices

Exynos 8890 — four variants, one platform.

All supported devices share the Samsung Exynos 8890 (Octa) SoC. Snapdragon variants are not supported.

Flash Guide

Step-by-step. No guesswork.

EylemROM is flashed via AnanJaser TWRP — not Odin. Follow each step in order. Skipping steps causes bootloops or mount errors.

Back up your data before proceeding. Flashing wipes all data — photos, messages, apps. Back up everything first. All files (SYSTEM.zip, Vendor+kernel+aroma.zip, repartitioner, cleaner) are linked in the XDA thread.
Step 01

Flash AnanJaser TWRP

  • Download AnanJaser TWRP from the XDA thread for your device
  • Boot into Download Mode: Vol Down + Home + Power (S7/S7E) or Vol Down + Bixby + USB-C (Note 7/FE)
  • Flash TWRP via Odin: AP slot → select TWRP .tar → Start
  • Once done, immediately boot into TWRP (Vol Up + Home + Power)
Step 02

Flash repartitioner & cleaner

  • In TWRP → Install → select the repartitioner zip → Swipe to Flash
  • Device will reboot back into TWRP automatically
  • Install again → select the cleaner zip → Swipe to Flash
Step 03

Fix any mount errors

  • Check if any partition shows "Unable to mount" in TWRP
  • If so: Wipe → Advanced Wipe → tap the affected partition
  • Tap Repair or Change Filesystem → Change Filesystem → select EXT4
  • Exception: for /data, change filesystem to F2FS instead
Step 04

Wipe partitions

  • Wipe → Advanced Wipe → select: Vendor (if it exists), Cache, Dalvik/ART Cache, Data
  • Swipe to wipe — this is a full clean install, no dirty flash
Step 05

Flash the ROM

  • Install → select (SYSTEM).zip → Swipe to Flash
  • Wait for it to complete fully before continuing
  • Install again → select (Vendor+kernel+aroma).zip → Swipe to Flash
  • The Aroma installer will open — follow the on-screen options to configure your ROM
Step 06

Reboot & troubleshooting

  • Reboot System — first boot takes 3–8 minutes, wait it out
  • Bootloop: go back to Step 04, re-wipe, and reflash both zips
  • Mount errors after wipe: repeat Step 03 for the affected partition
  • Still stuck: post in the Telegram discussion group
