Version Comparison: V1.0.5 vs. V1.0.4
To understand the value of this update, we need to look at where it came from.
| Feature | Mysterious-Dev Tool V1.0.4 | Mysterious-Dev Tool V1.0.5 |
|---|---|---|
| Primary Focus | New Features & VoLTE expansion | Stability polish & language support |
| Samsung FRP | Added Direct MTP Mode FRP Reset for Android 16 (No Test Point required) | Maintains full Android 16 FRP support |
| Connectivity | Standard ADB connectivity | Improved ADB stability with Smart List UI |
| Samsung Translate | Basic translation support | Fixed & expanded support for Android 11–16, 30+ new languages added |

Real Life Example: Solving the "Language Barrier & Dead Network"
Imagine a customer walks into your shop with a Samsung Galaxy S21 imported from the UAE. They are now using it in the UK, but they have two specific problems:
- The system language is stuck in a region they don't understand, and settings won't switch to English.
- VoLTE (4G Calling) isn't working on their UK Vodafone SIM, causing poor call quality.
How you solve it with Mysterious-Dev Tool:
- Step 1: You launch Mysterious-Dev Tool V1.0.5.
- Step 2: You navigate to the Samsung Services section and select the Translate module. Thanks to the V1.0.5 update, you select "English (United Kingdom)" and "Arabic (UAE)" to inject the necessary locale files. The system successfully applies the change, fixing the interface language.
- Step 3: For the network issue, you go to the New Menu (CDMA / VoLTE). You select Samsung VoLTE / IMS Features and choose "Enable VoLTE [Assistant]."
- Result: The device reboots. The interface is now in English, and the 4G icon appears in the status bar with "HD" next to it, indicating active VoLTE. You have fixed a software-level incompatibility that would have otherwise required a full, risky firmware flash.
