Backup Data: Flashing or bypassing locks using this method will wipe all user data. A write-up on the vivo V9 Pro prog_emmc_firehose

Check Model: Ensure your device is the PD1730CF (Pro) and not the standard V9 (PD1730F) or V9 Youth (PD1730BF), as using the wrong firehose can hard-brick the device.

Battery Level: Ensure the phone has at least 50% charge before attempting to flash.

V9 Pro Funtouch OS PD1730CF_EX_A_6.70.10 System Update - Vivo

It sounds like you’re looking for QFIL / Firehose programming files for the vivo V9 Pro (likely model 1727) from around 2021.

However, there are important points to consider:

  1. No official “vivo V9 Pro” exists – The vivo V9 (standard) and vivo V9 Youth exist. The “V9 Pro” branding is sometimes used interchangeably with the Indian variant of the vivo V9 (6GB RAM version, SD660).

    • Model numbers: 1727, 1726, 1724 (Snapdragon 660, codename PD1727).

  2. Firehose files (prog_emmc_firehose_*.elf) are proprietary Qualcomm files. vivo does not release them publicly.

  3. Where to find them (unofficially):

    • EDL firmware packages (usually .ofp or .ozip + rawprogram0.xml) for vivo devices sometimes contain a firehose.elf or prog_emmc_firehose_*.
    • Check forums like:
      • XDA Developers (vivo V9 section)
      • 4pda (Russian, but often has EDL files)
      • GSM-Forum (paid access usually required)
    • Search for:
      PD1727_firehose.elf
      vivo V9 1727 EDL firmware 2021
      prog_emmc_firehose_660.elf

  4. Security note – vivo uses Qualcomm Secure Boot (SBL + SHA256 RSA). A generic firehose will not work. You need one signed specifically for that device’s secure boot chain. Using an incorrect firehose may brick the device.

  5. 2021 context – By 2021, vivo had already locked down most EDL access. You might need an authorized vivo EDL tool (e.g., Vivo Tool, UnlockTool, Hydra Tool) to bypass authentication.

Recommendation:
If you just want to flash or unbrick your vivo V9 Pro, use vivo’s official flashing tool (usually offline flashing requires an authorized service account). For EDL/firehose access, search specific GSM forums or contact a professional repair service.
