ZTE Blade V2020 (4G LTE Model) / Blade A7s 2020 Firmware Flash File Download [Stock Rom]
This firmware is for the ZTE Blade V2020 (4G LTE model), which is also known in some regions as the ZTE Blade A7s 2020. Flashing the official stock firmware is the most effective method for fixing critical software errors, resolving bootloops, or completely restoring the device to its factory condition.
Important Note: The source filename for this package may incorrectly label it as “5G”. However, based on the MediaTek Helio P60 (MT6771) chipset and internal model number (P671F60), this firmware is exclusively for the 4G LTE version of the ZTE Blade V2020. Do not attempt to flash this on the actual 5G model. This process requires the SP Flash Tool.

How to Flash Using SP Flash Tool
- Install Drivers: Download and install the MediaTek USB VCOM drivers. If the installation fails on a modern Windows PC, you may need to disable Driver Signature Enforcement.
- Extract Files: Unzip the downloaded firmware package. Inside the extracted folder, you must locate the MT6771_Android_scatter.txt file. Also, extract the SP Flash Tool to a separate folder.
- Launch SP Flash Tool: Open the flash_tool.exe application from the tool’s directory.
- Load Scatter File: In the tool, click the “choose” button next to “Scatter-loading File” and select the MT6771_Android_scatter.txt file from your extracted firmware folder. The tool will populate with a list of device partitions.
- Select “Download Only”: Ensure the dropdown menu is set to Download Only. This is the safest flashing mode and should always be used first. Avoid “Format All + Download” to prevent erasing your device’s IMEI.
- Begin the Flash: Power off your ZTE Blade V2020 completely. Click the large “Download” button in SP Flash Tool.
- Connect the Device: Immediately connect your powered-off phone to the computer via a USB cable. SP Flash Tool will detect the device and the flashing process will begin automatically.
- Wait for Success: Do not disconnect the phone during the process. A successful flash is indicated by a large window with a green checkmark. You can then close the tool.
- Reboot: Disconnect your phone and hold the Power button to turn it on. The first boot after a full flash will take significantly longer than usual.
FAQs
Q1. Is this firmware really for the Blade V2020 5G?
No. Despite the original filename, this firmware is for the 4G LTE model of the Blade V2020 (model P671F60), which uses a MediaTek Helio P60 chipset. The actual Blade V2020 5G is a different device with a MediaTek Dimensity 800 chipset. Flashing this firmware on a 5G model will not work and will likely brick it.
Q2. What is a “scatter file” in MediaTek firmware?
A scatter file is a text file (.txt) that acts as a blueprint of the phone’s internal storage. It tells the SP Flash Tool the name, size, and location of each partition (like boot, system, recovery, etc.), ensuring the firmware is written to the correct place.
Q3. Will this firmware remove a carrier lock from a European carrier?
No. This is official stock firmware. It will restore the device’s software to its factory state but will not remove any network or SIM lock imposed by a carrier like Vodafone, Orange, etc.
Q4. SP Flash Tool is showing a BROM ERROR. What does that mean?
A BROM (Boot Read-Only Memory) error is a connection failure between the PC and the phone’s chipset. It is almost always caused by incorrect USB drivers, a faulty USB cable, or connecting the phone at the wrong time. Ensure your VCOM drivers are properly installed.
Troubleshooting (ZTE Blade V2020 4G)
- SP Flash Tool Does Not Detect Phone: This is the most common flashing problem. The solution is always driver-related. Re-install the MediaTek VCOM drivers, restart your PC, use a different USB port, and try a new USB cable.
- Error: “PMT changed for the ROM”: This error indicates a mismatch between the partition table on your phone and the one in the firmware. You can usually resolve this by changing the flashing mode in SP Flash Tool from “Download Only” to “Firmware Upgrade” and trying again.
- Device is stuck in a bootloop after a successful flash: The first boot can take 10-15 minutes. If it remains stuck after this period, you should boot into recovery mode (hold Volume Up + Power from an off state) and perform a “Wipe data/factory reset”.
- Lost IMEI or “Invalid IMEI” Error: This critical issue happens if you use the “Format All + Download” option, which erases the NVRAM partition. To avoid this, always use “Download Only” as your first choice.
