Motorola-Specific Notes

Boot Warning

After unlock, you'll see:

"Your device has been unlocked..."
Warning screen for few seconds at every boot

This is normal and doesn't affect function.

Stock Firmware

If you need stock firmware:

• Lolinet mirror has Motorola firmwares
• XDA device forums
• Some ROMs include firmware

Device Codenames

Find yours: Settings → About → look for codename

---

Troubleshooting

"Device Not Unlockable"

• Carrier-locked device
• Some regions restricted
• Not much you can do

Recovery Gets Replaced

Stock Motorola can replace recovery:

After flashing TWRP, immediately:
1. Boot directly to recovery
2. Flash Magisk before booting system

Bootloop After ROM Flash

1. Boot to TWRP
2. Try wiping data again
3. Reflash ROM
4. If persists, try different ROM

OEM Unlock Grayed Out

- Wait after first boot (some need days)
- Factory reset
- Connect to internet
- Try again

---

Relocking Bootloader

If returning to stock:

# ONLY on complete stock firmware!
fastboot oem lock

⚠️ Never relock with custom ROM - will brick!
