Flashing a Vivo 1801 (Vivo Y71) using the UMT (Ultimate Multi Tool) requires the correct firmware and a connection via EDL (Emergency Download) Mode. This process is typically used to fix issues like being stuck on the logo, auto-restarting, or a dead device. Prerequisites
UMT Dongle: Ensure your UMT Dongle is connected and the latest QCFire module is installed.
Vivo 1801 Flash File: Download the tested firmware for the Vivo Y71 (PD1731F).
Qualcomm USB Drivers: Install these on your PC so the device is recognized in EDL mode.
Backup: Flashing will erase all data. If the phone still boots, back up your files first. Step-by-Step Flashing Guide 1. Prepare the Device (EDL Mode)
The Vivo 1801 uses a Qualcomm Snapdragon processor and must be put into EDL Mode (9008) to flash: Power off the device. Remove the back cover to access the motherboard.
Locate the EDL Test Points (usually two small gold dots near the battery connector). Vivo 1801 Flash File Umt
Short these two points using tweezers while simultaneously plugging the USB cable into the PC.
Check your PC's Device Manager; it should show "Qualcomm HS-USB QDLoader 9008." 2. Configure UMT QCFire Open the UMT QCFire tool on your computer. Go to the Flash tab.
Set the Programmer (Patch) and XML files by browsing to the folder where you extracted the Vivo 1801 firmware. Select the prog_emmc_firehose_xxxx.mbn file. Select the rawprogram0.xml and patch0.xml files. 3. Start the Flashing Process Click the Flash button in the UMT interface.
The tool will begin writing the firmware to the device. Ensure the connection remains stable.
Once finished, you will see a "Flash Done" or "Operation Finished" message. 4. Final Reboot Disconnect the phone and reconnect the battery. Press and hold the Power button to turn it on.
The first boot may take 5–10 minutes. If the phone shows an IMEI error or invalid baseband after flashing, you may need to perform an IMEI repair or a factory reset using the code *#558#. Important Troubleshooting
Dead after Flash: If the device dies after a format or flash, ensure you are using the correct version of the tested flash file.
FRP Lock: If the phone asks for a Google account after flashing, you can use the "Reset FRP" button in UMT's "Read & Tools" tab while in EDL mode.
