As a mobile technician dealing with Honor X6c devices, it is important to know the ISP (In-System Programming) pinout because you will need it to complete more complicated processes such as unbricking, flashing, FRP bypass, and data recovery. Within this guide, I will show the ISP pinout of the Honor X6c using a diagram with some instructions as well.
What is ISP Pinout?
ISP (In-System Programming) pinout is the ability to directly interface a device’s eMMC or UFS storage to a professional tool for hardware-related processes. This is ideal, especially if the phone is not recognised in any other mode, or the device is dead, but the storage chip is still healthy.
EMMC Isp Pinout is useful when:
- Phone is dead (black screen, no boot, no charging)
- FRP is locked, and you can’t use ADB, fastboot, or OTG bypass
- You need to dump firmware from a working unit to repair a dead one
- You’re working on a boot repair or partition restore
- Phone is detected as “unknown” in PC (EDL not working)
Honor X6c ISP Pinout EMMC Ways Image:
Honor X6c has a hardware layout similar to other Realme and Oppo devices, but ISP pinout can be slightly different. You can usually find ISP points near the EMMC chip, which is located below the metal shield.
CMD – Command line
CLK – Clock signal
DAT0 – Data line 0
VCC / VCCQ – Power supply for the EMMC (can be powered via USB)
GND – Ground connection
💡 Tip: Use a microscope or a 10x magnifier to identify the points correctly. Don’t rely solely on diagrams—confirm the layout visually.
To fix dead boot issues on devices such as Honor X6c, equipment such as easy JTAG Plus and UFI boxes are highly effective. These professional repair equipment are particularly useful when a phone is flashly flashing, failing to show the boot logo, and does not respond to power.
Required Tools for ISP Pinout:
- Make sure your bench is set up with the right tools before jumping in:
- UFI Box, Easy JTAG, or Medusa Pro
- 0.1mm – 0.3mm jumper wire
- Fine tip soldering iron
- Isopropyl Cleaner (IPA 99%)
- Soldering flux
- Multimeter (for checking continuity)
How to Connect Honor X6c ISP Pinout to the UFI Box
- Remove the battery from the phone – extremely important to prevent voltage conflicts.
- Clean the PC board area using isopropyl alcohol.
- Connect jumper wires to CLK, CMD, DAT0, GND, and VCC with care using solder.
- Connect the wires to your EMMC tool following the tool’s pinout.
- Double-check each wire using a multimeter to ensure there are no shorts.
- Turn on your EMMC tool and scan the chip in software.
- ✅ If you have the right connection, you will see EMMC chip information in the tool window.
✅ If you have the right connection, you will see UFS chip information in the tool window.
