If you are searching for the Realme C55 UFS ISP Pinout, you have come to the right place. In this guide, we provide you with the full ISP pinout of the Realme C55 mainboard. This pinout is highly useful for mobile technicians and repair experts who deal with advanced repair work. You can use it in EDL mode (emergency download mode) or for dead boot repair issues, FRP (Factory Reset Protection) unlock or while working on devices while flashing firmware.
Additionally, Realme C55 ISP pinout supports popular tools such as easy JTAGs, UFI box, Hydra tool and data recovery, partition repair, or other professional repair solutions for dead devices. Whether you are fixing software corruption, unlocking of security locks, or recovering lost data, access to the correct ISP pinout will make the repair process easier and more reliable.
What is ISP (In-System Programming)?
In simple terms, ISP allows you to access the EMMC chip without having to remove it. You simply have to identify the appropriate pinout of the board, and you have to utilize a supported UFS, EMMC tool such as UFI, Easy JTAG, or Medusa Pro to attach it directly.
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)
Realme C55 ISP Pinout EMMC Ways Image:
Realme C55 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.
EMMC ISP Pin Labels You Need:
CMD – Command Line
CLK – Clock
DAT0 – Data line 0
VCC / VCCQ – Power supply for EMMC
GND – Ground
💡 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 Realme C55, 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.
