UnlockTool 2025.01.20.0 is a "maintenance release" done right. It doesn't reinvent the wheel, but it polishes the existing one significantly. The Samsung budget 5G support is timely (these devices are flooding repair shops), and the stability fixes make long flashing sessions less stressful.
Recommendation: Download and update. It’s safe, stable, and better than the December build. Just don't expect miracles on new Snapdragon Samsung flagships.
Rating: 8.5/10
Price: $150/year (Subscription) – Worth it for volume repair shops; overkill for hobbyists.
Pro Tip: After updating, clear the C:\UnlockTool\Logs folder to free up space, and run the "Test Server" button once to cache the new Samsung auth tokens.
Below is the comprehensive breakdown of what has been fixed, added, or optimized: UnlockTool-2025.01.20.0 Released Update
For professional shops running the UnlockTool software on a server (using the official WiFi dongle) while performing flash operations on disconnected networks, stability has been improved. The update kills the random "Server Connection Reset" error (Error Code: 0x502) that plagued the December 2024 version.
