Android ROM Quick-Start (10 minutes)

TL;DR version — just the essentials.

Step 1: Unlock Bootloader (5 min)

Pixel/OnePlus: Fastest

adb reboot bootloader
fastboot flashing unlock
# Device wipes. Tap to confirm on screen.
adb reboot

Samsung: Slower (carrier dependent)

• Settings → About → tap Build Number 7× → OEM Unlocking
• Reboot to Download Mode: Vol Down + Bixby + Power
• Open Odin → select recovery.tar.md5 in BL slot → Start
• Takes 5-10 min

Xiaomi: Waiting required

• https://unlock.mi.com — apply, wait 30-72 hours
• Then use Mi Unlock Tool (Windows only, unfortunately)

Step 2: Flash Recovery (2 min)

adb reboot bootloader
fastboot flash recovery twrp.img   # or your recovery of choice
fastboot reboot recovery

Step 3: Flash ROM (2 min)

In TWRP recovery:

Install → Select ROM.zip → Swipe to install
(optionally install GApps.zip, then Magisk.zip)
Reboot System

Boom. You're done. First boot takes 30-60 seconds while it optimizes.

What to do after

1. Check for updates: Most ROMs auto-update now
2. If you want root: Install Magisk via Magisk Manager app
3. If you want privacy: Check android-privacy-guide
4. If things break: Boot to TWRP, restore backup (you made one, right?)
