Samsung Galaxy A01 is a classic entry-level device that often struggles with the weight of modern Samsung One UI updates. For many enthusiasts, the solution is a Custom ROM
Installing a custom ROM on this entry-level hardware (Snapdragon 439 with 2GB RAM) can significantly improve the user experience:
- Unlock the Bootloader: Go to Developer Options > Enable OEM Unlocking. Reboot to Download mode and long-press Volume Up to unlock.
- Install a Custom Recovery: Use
Odinto flash TWRP (Team Win Recovery Project) built for the A01. - Disable Encryption: Format Data (the one where you type "yes") in TWRP. Then flash
Disable_Dm-Verity_ForceEncrypt. - Flash the ROM: Copy your GSI
.imgfile or LineageOS zip to an SD card and flash via TWRP. - Reboot: First boot takes 5–10 minutes. Be patient.

The Samsung Galaxy A01 (SM-A015) is a budget-tier device, which traditionally limits its custom ROM scene. While it does not have a massive library of device-specific ROMs like flagship models, it is highly compatible with Generic System Images (GSIs) due to its Project Treble support.

Note: Availability depends on the specific A01 model/region (SM-A015, SM-A015F, etc.). Always match ROM to the exact model codename.
