| Error | Fix | |-------|-----| | BROM ERROR: S_DA_... | Bad USB cable/port → use USB 2.0, remove hubs | | Driver not signed | Disable driver signature enforcement (Windows: Shift + Restart → 7 → reboot) | | PAC file checksum fail | Redownload firmware – file is corrupted | | S_DL_GET_DRAM_SETTING_FAIL | Wrong FDL/Firmware for this exact v75 variant → find exact build number | | Stuck at 8% | Replace battery, check flash chip (eMMC may be dead) |

This is critical. A V75 phone may come with either a MediaTek (MTK) or Spreadtrum (SPD) chipset. If you flash an SPD file on an MTK device, you will hard brick it.
