The screen went black. No download mode. No recovery. Nothing. The Note 5 was a hard brick—the eMMC chip corrupted.
The journey began.
But the thread mentioned an exploit: "CID 15" or "Shop Samsung" models. Mine wasn't one. After two days of frantic Googling, I found a guide. It wasn't an unlock; it was a bypass using a leaked engineering kernel. The risk: bricking the phone into a permanent "Secure Fail: Kernel" state.
The custom ROM journey on the Note 5 wasn't about getting a new phone. It was about rebellion against planned obsolescence. For 3 glorious months, a 7-year-old phone ran circles around budget 2022 phones. It was frustrating, terrifying, and utterly glorious. Would I do it again? In a heartbeat. Just... with a shorter USB cable. custom rom samsung note 5
But Samsung’s "Auto-Reboot" is a trap. If the phone boots normally after TWRP flash, the stock ROM overwrites it. I had to hold the millisecond Odin said "RESET," then quickly switch to Volume Up + Home + Power .
I had downloaded (Android 12L) and NikGapps (Google Apps) on my PC. The Note 5's USB port was finicky—one slight movement and the connection dropped.
Next, . This is the custom recovery that lets you flash ROMs. I downloaded twrp-3.6.0_9-0-noblelte.img.tar and flashed it via Odin. The screen went black
I wanted to throw it away. But then, I saw a glimmer of hope on XDA Developers: "LineageOS 19.1 (Android 12L) for Samsung Note 5 - Unofficial."
The blue bar crawled… 25%... 50%... 75%...
Inside TWRP, I performed a full wipe : Dalvik, System, Data, Internal Storage. Everything. My Note 5 was now a blank slate. No OS. A digital ghost. The screen said: "No OS Installed! Are you sure?" I swiped to confirm. Nothing
Prologue: The King in Winter
The phone rebooted to a screen that said "KERNEL IS NOT SEANDROID ENFORCING" in red letters – a beautiful warning. I was in.
The screen went black for 10 seconds. Too long. Panic. Then, the boot animation appeared: a circular logo spinning. And spinning. And spinning for 12 minutes (first boot always takes forever).
Custom ROMs require an unlocked bootloader. Samsung phones, especially the US and Canadian variants, are notorious for locked bootloaders. My heart sank as I checked my model number: (Canadian). Locked. Impossible.
I failed twice. On the third try, I saw the blue TWRP splash screen. I let out a breath I didn’t know I was holding.
