The ZTE Blade V2020 (also sold as the ZTE Blade A7s 2020 or A1 Alpha 20 Plus in some regions) is a capable mid-range smartphone featuring a large display and a quad-camera system. If your device is experiencing significant software issues like being stuck in a bootloop, suffering from app crashes, or has failed to boot altogether, a full firmware re-flash is the most effective solution.
Important Note: This device is powered by a MediaTek Helio P60 (MT6771) chipset. The restoration process requires the SP Flash Tool and the official scatter-based firmware. This specific firmware package is for the EEA (European Economic Area) region and will restore your device to its original factory software.

How to Flash Using SP Flash Tool
- Install Drivers: Download and extract the MediaTek USB VCOM drivers. Run the installer. If you face issues on Windows 10/11, you may need to disable Driver Signature Enforcement first.
- Extract Files: Unzip the downloaded Firmware package. You must be able to see a file named MT6771_Android_scatter.txt. Also, extract the SP Flash Tool to a separate folder on your PC.
- Launch SP Flash Tool: Open the tool’s folder and double-click on flash_tool.exe.
- Load Scatter File: In the tool, click the “choose” button next to the “Scatter-loading File” field. Navigate to your extracted firmware folder and select the MT6771_Android_scatter.txt file.
- Set Flash Mode: Ensure the dropdown menu is set to “Download Only”. This is the safest mode. Avoid using “Format All + Download” as it can erase your device’s IMEI number.
- Start the Process: Power off your ZTE device completely. Click the large green “Download” button in SP Flash Tool.
- Connect Your Phone: Immediately connect your powered-off phone to the computer via a USB cable. The tool will detect it and the flashing process (indicated by a progress bar) will begin automatically.
- Wait for Completion: Do not disconnect the phone. The process is complete when a large window with a green checkmark appears. You can now close the tool and disconnect your device.
- Reboot: Power on your phone. The first boot after a full flash will take significantly longer than usual, so be patient.
FAQs
Q1. What is a “scatter” file?
A scatter file (.txt) is a crucial component of MediaTek firmware. It acts as a map, telling the SP Flash Tool the memory layout of the device and which firmware files (like system.img, boot.img, etc.) should be written to which specific memory addresses or partitions.
Q2. What is the difference between “Download Only”, “Firmware Upgrade”, and “Format All + Download”?
Download Only: The safest mode. It flashes only the partitions listed in the scatter file and won’t erase critical data like your IMEI. Use this by default.
Firmware Upgrade: A more comprehensive mode that can resolve errors like “PMT changed for the ROM”. Use this if “Download Only” fails.
Format All + Download: A dangerous mode that erases the entire flash memory, including your IMEI number in the NVRAM partition. Avoid this unless you are an expert and have an NVRAM backup.
Q3. I got a BROM ERROR in SP Flash Tool. What does that mean?
A BROM (Boot Read-Only Memory) error typically indicates a failure in the initial communication between the PC and the phone’s chipset. This is almost always caused by incorrect USB drivers, a faulty USB cable, or not connecting the phone promptly after clicking the “Download” button.
Q4. Will this firmware remove a carrier lock?
No. This is official stock firmware. It will restore the device to its original software state but will not remove any existing network or SIM lock that was placed on it by a carrier.
Troubleshooting (ZTE Blade V2020)
- SP Flash Tool Does Not Detect the Phone: This is the most common issue and is 99% driver-related. Re-install the MediaTek VCOM drivers, try a different USB port (USB 2.0 is often more reliable), use a different USB cable, and ensure the phone is fully powered off before connecting.
- Error: “PMT changed for the ROM”: This error occurs when the partition table on your phone does not match the one in the firmware you are trying to flash. To fix this, change the flashing mode from “Download Only” to “Firmware Upgrade” and try again.
- Phone is stuck in a bootloop after a successful flash: The first boot can take up to 15 minutes. If it is still stuck after this time, boot into recovery mode (usually by holding Volume Up + Power from a powered-off state) and perform a “Wipe data/factory reset”.
- Lost IMEI / NVRAM Warning: This can happen if you used the “Format All + Download” option. Restoring the IMEI is an advanced procedure and requires specialized tools. To avoid this, always use the “Download Only” mode first.
