What is ISP (In-System Programming)?
In simple terms, ISP allows you to access the EMMC or UFS 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)
