Q1. I got an "Invalid IMEI" error after flashing. How do I fix it?

This error is caused by erasing the NVRAM partition, which happens if you use the "Format All + Download" option in SP Flash Tool. This stock firmware, when flashed in "Download Only" mode, will not fix a pre-existing IMEI issue. You will need a specialized tool like Maui META to restore your original IMEI numbers (usually found on the device's box or under the SIM tray).

Q2. SP Flash Tool shows a BROM ERROR. What should I do?

BROM errors are common and can be caused by several factors. First, try using a different USB port and a high-quality cable. Ensure the VCOM drivers are correctly installed. You can also try holding a volume button (Up or Down) on the tablet while connecting it to the PC after clicking "Download".

Q3. My tablet is completely dead and isn't detected by the PC. Is it fixable?

Yes, this is often a "hard brick" and is exactly what SP Flash Tool is designed to fix. The key is correctly installing the MediaTek VCOM drivers. You may need to disable Windows Driver Signature Enforcement to install them. Once the drivers are set up, the tool should detect the device when you connect it in its powered-off state.

🔧 Device-Specific Troubleshooting

“PMT changed for the ROM” Error: This error in SP Flash Tool means the partition layout of the firmware is different from what’s on your device. To resolve this, change the flashing mode from “Download Only” to “Firmware Upgrade.” This option will re-format the device to match the new layout. Be aware this erases all data.
Stuck in Bootloop After Successful Flash: If the tool shows a green checkmark but the device won’t boot past the Acer logo, it needs a factory reset. Power it off, then boot into recovery mode (hold Power + Volume Up). In the recovery menu, select “Wipe data/factory reset” and then “Reboot system now.”
No 4G/LTE Signal After Flashing: If your tablet can no longer detect a SIM card or connect to mobile data, it’s likely an NVRAM/modem issue. First, re-flash the firmware using “Download Only” mode. If that fails, the NVRAM partition may be corrupted, a complex issue that can sometimes be fixed by restoring the IMEI.
Red Progress Bar in SP Flash Tool: A red bar that appears and stops usually indicates a driver or connection issue. Your PC is detecting a device, but the VCOM driver isn’t loading correctly to start the data transfer. Re-install the drivers and try again.
