Using a UFS adapter board (e.g., EasyJTAG, Medusa Pro), you need to map the pinout correctly. Misconnecting VCCQ (1.2V) to a 3.3V programmer port is a common cause of permanent chip death.
I/O supply voltages (typically 1.2V for VCCQ and 1.8V for VCCQ2) 🔍 ISP (In-System Programming) Pinout ufs 3.1 pinout
UFS 3.1 is backward compatible with UFS 2.1 pinouts, but VCCQ2 (1.2V for advanced low-power states) is more common. Missing VCCQ2 may prevent HS-G4 (Gear 4) speeds. Using a UFS adapter board (e
During power-up, these pins are sampled to determine boot mode (e.g., normal boot vs. forced download mode). Accidentally pulling these low can prevent the chip from responding to the host. Missing VCCQ2 may prevent HS-G4 (Gear 4) speeds
