The EFT Pro Dongle has just released its latest update V5.3.8 Build 001, bringing significant enhancements to mobile technicians' toolkit.

Version Comparison: What's Changed Since V5.3.7

The V5.3.8 update builds upon the foundation laid by V5.3.7, which introduced MTK support for Lenovo devices and Qualcomm support for additional Samsung models. While V5.3.7 focused on expanding device compatibility across multiple manufacturers, V5.3.8 hones in specifically on Samsung's Qualcomm-based devices.

Key Differences:

Focus Shift: V5.3.7 had a broader scope with MTK and Qualcomm support for both Samsung and Lenovo, while V5.3.8 concentrates exclusively on Qualcomm-based Samsung devices.
New Manufacturer: V5.3.8 introduces REDMI K90 support, marking the first inclusion of this device in the EFT Pro ecosystem.
Samsung Model Expansion: V5.3.8 adds 14 new Samsung models compared to the 12 added in V5.3.7, with a focus on popular series like Galaxy S21, Z Fold3, and Z Flip3.
Functionality Refinement: While both versions support FRP and Factory Reset, V5.3.8 appears to have refined these features specifically for the newly added Samsung V2 models.

Practical Scenario: Resolving a Samsung Galaxy S21 Ultra FRP Lock

Consider a common scenario: A customer brings in a Samsung Galaxy S21 Ultra (SM-G998U) with a FRP lock after a factory reset. The customer doesn't remember their Google account credentials, preventing them from accessing their device.

Before the V5.3.8 update, technicians might have struggled with this specific BIT I version of the device. Now, with the updated EFT Pro Dongle, the process becomes straightforward:

Connect the Samsung Galaxy S21 Ultra to the computer via USB
Launch the EFT Pro Dongle software
Select the Qualcomm module
Choose the Samsung Galaxy S21 Ultra (SM-G998U) – BIT I from the device list
Select the FRP removal option
Follow the on-screen instructions to complete the process

Within minutes, the FRP lock is removed, and the customer can access their device. This streamlined process not only saves time but also enhances customer satisfaction, demonstrating the practical value of the V5.3.8 update for mobile repair businesses.
