How to Flash the Stock Firmware
Flashing the stock ROM onto your ZTE Blade A452 requires a Windows PC and the SP Flash Tool. The process involves installing the MediaTek VCOM drivers, loading the MT6735_Android_scatter.txt file from your chosen firmware into the tool, and then connecting your powered-off phone to start the flash.

Device-Specific Troubleshooting for ZTE Blade A452
- Correct Driver Installation: The most common failure point is incorrect drivers. If the tool doesn’t see your phone, you must install the MediaTek VCOM drivers, which often requires you to disable ‘Driver Signature Enforcement’ in Windows first.
- MT6735 vs MT6735M Chipset Variants: The Blade A452 was produced with both the MT6735 and the slightly different MT6735M chipsets. While the firmwares are often interchangeable, if one version fails to flash or causes boot issues, try the other version provided. The safest bet is to flash the firmware that matches the chipset your device originally came with.
- Using the “Boot Key”: To initiate the flash, power the phone off completely. Press and hold the Volume Down button, and while holding it, connect the phone to your PC. If that fails, try the Volume Up button.
- Safer Flashing (Uncheck Preloader): For a safer flashing process that is less likely to cause a hard brick, it is highly recommended to uncheck the `preloader` partition in SP Flash Tool before clicking Download. Flashing an incorrect preloader is the most common cause of a permanently dead phone.
FAQs
Q1. How can I tell which chipset my Blade A452 has?
If your phone can boot, an app like AIDA64 from the Play Store will show the exact processor model (MT6735 or MT6735M). If the phone is bricked, you may not be able to tell easily, in which case you can try flashing one firmware and, if it fails, try the other.
Q2. My phone’s battery drains quickly. Will flashing this ROM fix it?
Flashing the stock ROM can solve software-related battery drain caused by rogue apps or system bugs. However, as this is an old device, the physical battery has likely degraded over time. If the drain persists after a clean flash, the battery hardware itself is probably the cause.
Q3. What is a “scatter file”?
The scatter file (e.g., MT6735_Android_scatter.txt) is a crucial map for MediaTek firmware. It tells SP Flash Tool the name, size, and location of every partition on the device’s storage, ensuring each part of the software is flashed to the correct place.
Q4. Will this process erase my data?
Yes. Flashing the stock ROM with SP Flash Tool will perform a full factory reset and completely wipe all personal data, apps, and settings from your device.
