This process will completely erase all personal data from your phone's internal storage.

Ensure the battery has at least a 50% charge to prevent any interruptions during flashing.

Windows PC & USB Cable:

You will need a Windows computer, a quality micro USB data cable, and the correct drivers.

"S_BROM_DOWNLOAD_DA_FAIL" Error in SP Flash Tool:

This is a common error with MT6580 devices. It points to an issue with the Download Agent file or the USB connection. First, try using a different USB port and a high-quality cable. If the error continues, try using a newer version of SP Flash Tool, as it may contain an updated Download Agent compatible with your device.

Phone Vibrates but the Screen Stays Black after Flashing:

This often indicates that the wrong firmware was flashed, leading to a display driver mismatch. Double-check that your phone is the T06 3G model. If you are certain it is the correct model, the issue could be a loose display connector or a hardware fault with the screen itself.

Stuck on Acer Logo After Flashing:

If the flash was successful but the phone won't boot, you need to perform a factory reset. Power off the phone, then boot into recovery mode by holding Power + Volume Up. In the recovery menu, select "wipe data/factory reset" and confirm. This will erase your data but should fix the bootloop.

SP Flash Tool Red Bar Error (Stops at 0% or 100%):

A red progress bar means the PC detected a device, but the VCOM drivers failed to initialize properly for data transfer. The solution is to completely uninstall and reinstall the MediaTek VCOM drivers. You may need to disable Driver Signature Enforcement in Windows during installation.

❓ Frequently Asked Questions (FAQs)

Q1. Will this firmware work on my Acer Liquid Zest 4G?: No, absolutely not. This firmware is for the 3G model (T06, MT6580 chipset). The Liquid Zest 4G model uses an MT6735 chipset and requires different firmware. Flashing this file on the 4G model will result in a hard brick.
Q2. My phone has no sound after flashing. How do I enable DTS HD Sound?: This stock ROM will restore the original DTS HD Sound software. If you have no sound, first check your volume levels. Then, go to Settings > Sound & notification and look for the DTS settings to ensure they are enabled. If the problem persists, it may be a hardware failure with the phone’s speaker.
Q3. I lost my IMEI number. Will flashing this firmware fix it?: No. An invalid or lost IMEI is caused by erasing the NVRAM partition, which usually happens by using the “Format All + Download” option in SP Flash Tool. Flashing this stock firmware in “Download Only” mode will not restore a lost IMEI. You need a separate tool, such as Maui META, to rewrite your original IMEI.
