Moto G85 5G UFS ISP Pinout and Test Point
Welcome back to MobileRdx. For advanced mobile technicians who are working with dead-boot repairs, data recovery, or severe software bricks on modern devices, traditional ISP methods are no longer an option.
We’re going to take a look at the Motorola Moto G85 5G today, which is powered by the Qualcomm Snapdragon 6 Series Gen 3 (SM6375) processor. Due to its high degree of integration and lack of easy surface test points, we must use the highly advanced CPU drill method in order to get access to the device’s UFS memory.
⚠️ WARNING: This procedure is strictly for professional micro-soldering experts. Grinding the CPU carries an extremely high risk of permanently dead-bricking the motherboard. Proceed with caution.
What is the Moto G85 5G ISP pinout?
When a device is “hard-bricked” or has a corrupted partition table, standard USB flashing often fails. In these cases, we use the ISP method. This involves soldering tiny wires to specific test points on the motherboard to interface directly with the device’s storage (UFS/eMMC) without removing the chip.
Using special soldered jumper wires attached to either test points or resistors on the logic board, you can bypass the faulty CPU, then read the information right out of the memory chip using one of these programmer boxes, such as a Flash64, Easy JTAG Plus, Medusa Pro II, or UFI Box.

Compared to older eMMC chips that use CMD, CLK, and DAT0, the Moto G85 5G utilizes high-speed Universal Flash Storage (UFS). This means you must interface with differential signaling lines.
RX_0P (Receive Positive)
RX_0N (Receive Negative)
TX_0P (Transmit Positive)
TX_0N (Transmit Negative)
Note: You will also need to supply VCC (typically 2.95V), VCCQ (1.2V or 1.8V depending on the UFS specification), and GND. These power lines can usually be safely disconnected from the surface capacitors rather than drilling the CPU.
Required Tools for ISP Pinout:
Make sure your bench is set up with the right tools before making jumpers.
- Flash64 Box UFI Box, or Easy JTAG
- 0.1mm – 0.3mm jumper wire
- Fine tip soldering iron
- Isopropyl Cleaner (IPA 99%)
- Soldering flux
- Multimeter (for checking continuity)
How to Connect Moto G85 5G ISP Pinout ISP to the UFS Box
- Remove the battery from the phone—this step is extremely important to prevent voltage conflicts.
- Clean the PC board area with isopropyl alcohol.
- Connect jumper wires to Rst, Txop, Txon, Rxop, and Rxon points with care using solder.
- Connect the wires to your UFS/EMMC tool according to the tool’s pinout.
- Double-check each wire using a multimeter to ensure there are no shorts.
- Connect to UFI or Easy JTAG,
- In the UFI or Easy JTAG software:
- Select Identify UFS eMMC
- Now Use the Operation You Want: User Partition – Special Task – Reset FRP
If you have the right connection, you will see the UFS chip information in the tool window.
Frequently Asked Questions
A: UFS. It does not use eMMC (CMD/CLK/DAT0).
A: RX_0P, RX_0N, TX_0P, and TX_0N.
A: Tap VCC, VCCQ, and GND from surrounding surface capacitors. Do not drill for power lines.
A: The SM6375 sends memory traces through buried internal PCB layers. There are no surface test points.
A: You will break the differential copper traces, resulting in a permanent, unrecoverable dead brick.
A: UFS requires high-frequency signaling. Jumper wires must be as short as possible and equal in length to prevent signal degradation and data read errors.
