UAT PRO (Uni Android Tool)

UAT PRO Features Explained: FRP Bypass, Factory Reset, IMEI Repair, Firmware Flash & More

6 min read

Overview

UAT PRO is packed with repair functions covering the full range of problems Android technicians face daily. This guide explains each major feature in detail — what it does, why it matters, and which devices it targets — so you know exactly what your UAT PRO subscription delivers.

1. FRP Reset (Factory Reset Protection Bypass)

FRP is Android's security feature that activates after a factory reset, requiring the previously linked Google account before the device can be used. While designed to prevent theft, it creates a real challenge for technicians:

Customer forgot their Google account password
Second-hand phone with the previous owner's account still active
Device was factory reset without first signing out of Google

UAT PRO's FRP Reset works with a single click on nearly all supported Android brands. It is compatible with Samsung, Xiaomi, Oppo, Realme, Vivo, Tecno, Infinix, Lava, OnePlus, and many more across both MediaTek and Qualcomm platforms. FRP bypass is the most commonly used function in any mobile repair workshop.

2. Factory Reset (Format)

The Factory Reset feature performs a fast, reliable full wipe of an Android device — restoring it to factory default state. This removes:

All user data (contacts, apps, photos, accounts)
Screen lock, PIN, password, or pattern
Carrier and system customizations

UAT PRO performs this in one click, without needing recovery mode access or manual button sequences. It is particularly useful when a device has an unknown screen lock and the owner needs a fresh start, or when preparing a device for resale.

3. Security Repair

Android devices store critical security data in dedicated protected partitions. When this data becomes missing, corrupted, or incorrect — often after a failed firmware flash, a bad update, or an unauthorized tool — the device may exhibit:

Persistent "Security error" or "Device integrity compromised" messages
Failure to boot past the manufacturer screen
Loss of network registration (related to IMEI certificate integrity)
Knox or system integrity verification failures on Samsung devices

UAT PRO's Security Repair function recovers and restores the correct security state, bringing the device back to full, verified operation. This is especially valuable after board-level repairs or unrecognized flashing attempts.

4. Read Firmware (ROM Backup)

Before performing any risky repair, a technician should always back up the device's current firmware. UAT PRO's Read Firmware function creates a complete backup of the Android ROM directly from the device's storage partitions.

This backup serves two purposes:

Restore — if the repair goes wrong, the original firmware can be written back
Replicate — the same firmware can be flashed onto an identical device model, saving time when repairing multiple units

Read Firmware supports a wide range of MediaTek, Qualcomm, and UniSoc-based devices.

5. Write Firmware (Flash ROM)

UAT PRO's Write Firmware function flashes new or recovered firmware onto an Android device. Technicians use this to:

Repair devices stuck in boot loops or crash loops after a bad OTA update
Restore a soft-bricked device to a working state
Apply a specific firmware version for region compatibility or carrier requirements
Upgrade or downgrade firmware with precision

The tool supports a wide range of vendor image file formats and ensures compatibility with the target device model and chipset. It is compatible with scatter-file-based MTK flashing, Qualcomm EDL (9008) mode flashing, and UniSoc flashing protocols.

6. Bootloader Unlock & Lock

The bootloader is the first program that runs when a phone powers on. It verifies the OS integrity before loading Android. Manufacturers lock the bootloader to prevent unauthorized OS changes.

UAT PRO enables:

Bootloader Unlock — grants low-level system access, enables custom ROM installation and advanced partition operations. Required for many deeper repair procedures.
Bootloader Lock — re-locks the bootloader after repair work is complete, restoring the device to a factory-secured state ideal for resale or returning to the customer.

7. IMEI Repair

The IMEI (International Mobile Equipment Identity) is the 15-digit number that uniquely identifies every phone on a mobile network. A device with a null, corrupted, or missing IMEI cannot connect to any carrier — no calls, no SMS, no mobile data.

Common causes of IMEI corruption:

Failed firmware flash or incomplete update
Unauthorized tool modifying the baseband partition
Motherboard replacement without restoring the original identifier

UAT PRO restores the correct IMEI on supported models, bringing the device back to full carrier connectivity. Supported across Samsung, Xiaomi, Oppo, and many other brands on both MediaTek and Qualcomm platforms.

8. EFS Backup, Restore & Reset

The EFS (Encrypted File System) partition on Android devices stores the IMEI, certificates, and critical security identifiers. UAT PRO provides three EFS operations:

Backup EFS — saves a copy of the EFS partition before any risky operation
Restore EFS — writes back a previously saved EFS backup, recovering IMEI and security data
Reset EFS — clears the EFS partition when it is corrupted beyond repair (note: IMEI must be re-written separately after reset)

Backing up EFS before any firmware flash or board repair is considered best practice in professional repair workshops.

9. RPMB Read & Write

RPMB (Replay Protected Memory Block) is a secure hardware partition used by modern Android devices to store cryptographic keys, digital rights management data, and secure boot counters. UAT PRO provides direct RPMB read and write access for advanced technicians performing board-level repairs or handling devices with RPMB-related errors.

10. Partition Manager

The Partition Manager gives direct access to a device's storage partitions — boot, system, recovery, userdata, cache, and others. This enables advanced diagnostic and repair tasks that are not possible through standard recovery or ADB methods, making it a powerful tool for experienced technicians.

11. Health Check

The Health Check function runs a diagnostic scan of the device's hardware and software state before and after repair operations. It confirms that all key systems — network, storage, security — are functioning correctly, giving technicians confidence before handing a repaired device back to the customer.

Supported Operations by Chipset

One Subscription — All Functions

Unlike some competing tools that charge per-operation credits, UAT PRO operates on a flat subscription model. One active subscription gives you unlimited access to all features and all supported models for the full duration — no per-repair charges, no surprise credit deductions. This makes it extremely cost-effective for high-volume repair shops.
