I can provide you with a general guide on the Realme 5i (RMX2030) ISP pinout and how to reset a screen lock based on widely available technical knowledge up to February 25, 2025. This response will focus on the process typically used by mobile technicians to bypass screen locks (e.g., pattern, PIN, or password) using ISP (In-System Programming) methods with tools like UFI Box, Easy JTAG, or similar eMMC tools. Note that this is a technical procedure requiring specific hardware and expertise, and it should only be performed by those with the appropriate skills and legal authorization.
What is ISP Pinout?
The ISP pinout refers to the specific points on a device’s motherboard (e.g., eMMC chip) that allow direct communication with the memory to perform tasks like reading, writing, or wiping data. For the Realme 5i (RMX2030), this method is often used to bypass screen locks or FRP (Factory Reset Protection) when standard reset options are unavailable.
Prerequisites
Hardware Tools: UFI Box, Easy JTAG, or another eMMC-supported tool.
Software: UFI Box software (or equivalent) installed on a Windows PC.
Realme 5i Device: Fully charged (at least 80%) and powered off.
USB Cable: For connecting the device to the PC (if needed for detection).
Screwdriver and Tweezers: To open the device and access the motherboard.

Step-by-Step Guide to ISP Pinout and Screen Lock Reset
1. Gather the ISP Pinout Information
The Realme 5i (RMX2030) uses a Qualcomm Snapdragon 665 chipset with an eMMC storage chip. The ISP pinout typically involves connecting to the following eMMC pins:
CLK (Clock Signal)
DATA0 (Data Line)
GND (Ground)
VCCQ (Power supply for the eMMC, usually 1.8V or 2.8V)
Note: The exact pinout locations on the Realme 5i motherboard can vary slightly depending on the hardware revision. Unfortunately, I cannot generate or display an image of the pinout diagram directly. However, these points are usually located near the eMMC chip, which is a small rectangular component on the motherboard. Technicians typically refer to online forums (e.g., Martview Forum or GSM hosting sites) or service manuals for the precise diagram. Look for labels like “Realme 5i RMX2030 ISP Pinout” from reputable mobile repair communities.
2. Disassemble the Device
Power off the Realme 5i completely.
Remove the back cover using a plastic pry tool or screwdriver (check for screws under the SIM tray or back panel).
Disconnect the battery connector to avoid short circuits during the process.
Locate the eMMC chip on the motherboard (it’s often shielded or near the CPU).
3. Connect the ISP Pins
Using the ISP pinout diagram, identify the CMD, CLK, DATA0, GND, and VCCQ points.
Solder thin wires or use pogo pins (if your tool supports them) to connect these points to your eMMC tool (e.g., UFI Box adapter).
Ensure a stable connection, as loose contacts can cause detection failure.
Ground the connection properly to avoid damaging the chip.
4. Set Up the eMMC Tool
Launch the UFI Box software (or your chosen tool) on your PC.
Configure the tool to Qualcomm eMMC mode, as the Realme 5i uses a Qualcomm chipset.
Connect the ISP adapter to the PC via USB.
If prompted, select the Realme 5i (RMX2030) model or manually configure the eMMC settings (e.g., 1.8V or 2.8V VCCQ).
5. Detect the Device
Power on the device by reconnecting the battery or pressing the power button (depending on your tool’s requirements).
In the UFI software, click “Identify” or “Direct eMMC” to detect the memory chip.
If successful, the tool will display the eMMC details (e.g., size, manufacturer).
6. Reset the Screen Lock
Navigate to the “Special Task” or “Partition” section in the UFI software.
Select “Factory Reset” or “Wipe Data Only” (this clears the user data partition, including the screen lock).
Avoid wiping the entire eMMC unless necessary, as this could remove the firmware and require reflashing.
Click “Execute” or “Start” and wait for the process to complete (usually a few minutes).
7. Reassemble and Test
Disconnect the ISP connections and remove the wires/pins from the motherboard.
Reconnect the battery and reassemble the phone.
Power on the device. It should boot up without the screen lock.
Complete the initial setup process.
Important Notes
FRP Consideration: If FRP is enabled, you may need to wipe the “persistent” partition or use additional bypass methods after the screen lock reset.
Risks: Incorrect connections or voltage settings can damage the eMMC chip or motherboard. Proceed with caution.
Firmware: If the device fails to boot after the reset, you may need to flash the official Realme 5i (RMX2030) stock ROM using a tool like MSM Download Tool.
Legality: Ensure you have permission to perform this reset, as bypassing locks on a device you don’t own could be illegal.
Troubleshooting
Device Not Detected: Double-check the pinout connections and voltage settings (e.g., VCCQ at 1.8V instead of 2.8V).
Tool Errors: Update your eMMC tool’s software to the latest version (as of 2025).
Boot Issues: Reflash the firmware if the device becomes unresponsive.
