Flashing FloppyKernel for Exynos 1280

Before starting, note these things:

• You need an unlocked bootloader (of course).
• If it's your first time flashing anything custom (ROM, kernel, root, whatever), you WILL need to format data / factory reset to complete the process.
• Things like unlocking the BL, how to use Odin, how to use TWRP, etc... Are not explained here, you have to know beforehand.

Understanding the file naming

The name of the kernel file you are going to flash will tell you what it contains.

• "Vanilla": Unrooted, no extra modifications. Use this for rooting with Magisk.
• "KSUNext": Rooted with KernelSU Next.
• "Unlocked": The kernel has CPU and GPU overclock. Read the Release page for more info.

These can be combined, for example:

"Floppy_v5.4-KSUNext+Unlocked-exynos1280-20250719-2355.zip": means overclocked and rooted with KernelSU Next.

• "AOSP": This build is for AOSP ROMs.
• "OneUI": This build is for OneUI stock, port or modded ROMs.

You DO NOT need to worry about the ROM type if you are flashing the zip file! It detects automatically.

Flashing via recovery

Installing the recovery (skip if you already have):

• Reboot device to Download mode.
• Put your patched vbmeta TAR file in BL slot of Odin. You can patch your own vbmeta here or download this one (should work for all devices).
• Put your custom recovery TAR file in AP slot of Odin. You can get recoveries here.
• Flash and wait for it to reboot.
• Once screen turns off, hold Volume Up + Power to enter recovery mode.
• If it's your first time flashing something custom, you must factory reset by doing "Wipe -> Format Data".

Installing the kernel normally:

• Pick the correct ZIP file depending on what you want and copy it to an SD Card (TWRP cannot decrypt internal storage).
• In TWRP, go to "Install", find the file you copied, select it and swipe to flash. Done!
• Reboot and it should work.

Installing via ADB sideload:

• It's possible to simply ADB sideload the kernel (useful if you don't have and SD Card), but it's too long to explain here. Look up on YouTube how to use ADB sideload if you need to use this method. Alternatively, just use the Odin method.

Flashing via Odin

• Reboot device to Download mode.
• Put your patched vbmeta in BL slot of Odin. You can patch your own vbmeta here or download this one (should work for all devices).
• Pick the CORRECT file for your ROM type (AOSP or OneUI) and load it in the AP slot of Odin.
• Flash and wait for it to reboot. Done!
• If it bootloops, you will need to boot into recovery and perform a factory reset.
