To unlock the FRP (Factory Reset Protection) on a Samsung Galaxy A04s (SM-A047F) using Chimera Tool with the test point method, here’s a general guide based on common practices for this process. This method typically involves physically accessing the device’s test points to enter a special mode (like EUB or Emergency Download Mode) and using Chimera Tool to bypass the FRP lock. Note that this requires some technical skill and caution to avoid damaging the device.
Steps for Samsung A047F Test Point and FRP Unlock with Chimera Tool:
Preparation:
Ensure you have the latest version of Chimera Tool installed on your computer.
Download and install the necessary Samsung USB drivers on your PC.
Charge your Samsung A047F to at least 50% to avoid interruptions.
Gather tools: a USB cable, a small screwdriver, tweezers (or a thin metal pin), and an image or diagram of the A047F test point location (you can search online for “Samsung A047F test point” if needed).
Power Off the Device:
Turn off the Samsung A047F completely. If it’s FRP-locked and you can’t access the menu, remove the battery (if removable) or let it drain completely, then recharge it slightly before proceeding.
Disassemble the Phone:
Carefully remove the back cover of the Samsung A047F using a small screwdriver or plastic pry tool. Be gentle to avoid breaking clips or damaging the casing.
Disconnect the battery connector to ensure the device is fully powered off during the process. This step is crucial for safety and to prepare for test point shorting.
Locate the Test Point:
Identify the test points on the motherboard. For the Samsung A047F, these are typically two small gold or silver pads located near the battery connector or elsewhere on the mainboard. You may need to refer to a specific diagram for this model, as test point locations vary by device.
The test point allows the phone to boot into EUB (Exynos USB Booting) mode or a similar low-level mode required for Chimera Tool to interact with the device.
Short the Test Point:
Using tweezers or a thin metal pin, short the two test points by connecting them together. Hold them in contact while you proceed to the next step.
While keeping the test points shorted, reconnect the battery connector (if disconnected) and plug the USB cable into the phone and your computer. This should force the device into EUB mode.
Launch Chimera Tool:
Open Chimera Tool on your PC. Ensure your license is active and the software is updated.
The tool should detect the Samsung A047F in EUB mode. If it doesn’t, double-check your USB connection, drivers, and test point shorting technique.
Perform FRP Unlock:
In Chimera Tool, select the “Samsung” module and choose the SM-A047F model.
Navigate to the “Reset FRP Lock” or “Remove FRP” option (the exact wording may vary depending on the version).
Click “Start” or “Execute” to begin the FRP removal process. The tool will communicate with the device and bypass the Google account verification.
Wait for the process to complete. You’ll see a log in Chimera Tool indicating success (e.g., “FRP Lock Removed Successfully”).
Finish Up:
Once the FRP unlock is done, disconnect the USB cable and remove the short from the test points.
Reassemble the phone by reconnecting the battery and securing the back cover.
Power on the device. It should boot up without asking for the previous Google account credentials.
Verification:
Complete the initial setup process to confirm the FRP lock is no longer active. If successful, you can now use the phone normally or sign in with a new Google account.
Notes:
Test Point Accuracy: The exact test point location for the SM-A047F may differ based on the hardware revision (e.g., PCB ID). If unsure, search for a reliable diagram specific to your device’s binary version (e.g., U6, if applicable).
Chimera Tool Features: Chimera Tool supports multiple Samsung Exynos models in EUB mode for FRP removal without needing the #0# test mode, making it efficient for devices like the A047F.
Risks: This method involves hardware manipulation, so proceed carefully to avoid damaging the motherboard or voiding any warranty.
Software Updates: Ensure your Chimera Tool version supports the latest firmware on the A047F (e.g., Android 13 or 14, depending on the update as of February 25, 2025).
If you encounter issues (e.g., the device isn’t detected or the FRP removal fails), double-check the test point connection, USB cable, and drivers, or consult Chimera Tool’s support resources for model-specific troubleshooting. This process has been widely used and documented for Samsung devices like the A047F, especially with tools like Chimera, as of early 2025.
