As reported in various forums, many developers and repair technicians began hitting a wall when trying to flash Vivo phones, including the V9 Pro. When attempting to use the Firehose protocol via tools like QFIL, they were met with errors such as "INFO: Target Said: "Warning: Unauthorized tag 'program'" or an "SDCC Error 20" . This was a security feature implemented by Vivo, effectively "locking down" the EDL mode. Unlike some other brands, Vivo phones often require an authenticated Firehose loader, making it far more difficult for standard users to perform a low-level flash. In fact, a search for a Vivo Firehose loader will reveal that they are notoriously difficult to work with.

Even though the computer could detect the dead phone, the unauthenticated Firehose programmer was blocked by Vivo's security handshake. As one frustrated XDA user noted, "At first, you can't flash the vivo v9 pro without authorize service".

However, computer flashing tools cannot simply alter a phone's internal storage (eMMC or UFS) without authorization. This is where the file comes in:

Unfortunately, as per reports from 2021 and onward, bypassing this authorization is not possible with standard tools like QFIL alone. However, commercial and professional tools have since developed workarounds (detailed in the next section). The most reliable solution remains to use an authorized Vivo service center or a professional repair box that has licensed access.
