I own a Sunmi D3 Pro POS terminal (Qualcomm QCM4325, Android 13 / Sunmi OS 4.0.61). The device is locked with vendor software (DISH) POS system — I can’t install APKs or access Google Play. I want to flash stock firmware / ROM or restore it to native Android, keeping full touchscreen and printer functionality. What I need help with: Finding or extracting official Sunmi D3 Pro firmware / ROM (fastboot or EDL format). Providing a firehose loader + QFIL instructions, or Helping me unlock the bootloader or safely bypass kiosk restriction. I can provide full details: Build: Sunmi OS 4.0.61 / Android 13 CPU: QCM4325 Serial number, photos, ADB logs if required. Please respond only if you have firmware flashing experience (Qualcomm EDL, QFIL, or fastboot) or have worked with Sunmi devices (D2, T2, D3 Pro, etc.) before.
