Finally, press and hold the Volume Down button while connecting the tablet to your computer with a USB cable to initiate the flashing process.

Device-Specific Troubleshooting for Advan Tab 8
- Fixing Wi-Fi Connectivity Problems: This firmware is specifically labeled “5G WIFI.” If your tablet is having trouble connecting to 5GHz Wi-Fi networks, frequently disconnects, or has slow Wi-Fi speeds, a full firmware flash is the best solution. It will restore the original, stable wireless drivers and modem configuration.
- Tool is Stuck on “Checking Baudrate”: This is the most common error when flashing UNISOC/Spreadtrum devices and it indicates a driver issue. Uninstall and reinstall the UNISOC drivers, use a different USB port (a main one on the back of your PC is best), and try a different USB cable. Newer chipsets like the SC9863A may require the latest drivers.
- Entering Flash Mode: To start the process, you must hold a boot key. For the Advan Tab 8, this is typically Volume Down. If that doesn’t work, try holding Volume Up while connecting the powered-off tablet.
- “Failed: NV data backup” Error: If the flash fails with an NV data error, it’s having trouble with the partition that stores your IMEI and network data. As an advanced fix, you can go into the tool’s settings (double gear icon) and uncheck all “NV_” partitions before flashing. Warning: This will erase your IMEI number, which you will then need to restore using a separate tool. Only attempt this if a standard flash fails.
FAQs
- Q1. What does “5G WIFI” in the firmware name mean? Does my tablet have 5G?
- No. “5G WIFI” refers to the tablet’s ability to connect to 5 Gigahertz (5GHz) Wi-Fi networks, which are generally faster and less crowded than standard 2.4GHz networks. It does not mean the tablet supports the 5th Generation (5G) cellular data network.
- Q2. My Advan Tab 8 is completely dead (mati total). Will this firmware fix it?
- Yes. If the cause of the dead device is corrupted software (a “hard brick”), then flashing this official
.pacfirmware is the standard procedure to unbrick it and restore it to working condition. - Q3. The flash tool doesn’t detect my tablet. What’s wrong?
- This is a driver issue 99% of the time. Ensure the UNISOC SCI drivers are installed correctly. Open the Windows Device Manager before connecting your tablet; when you connect it while holding Volume Down, a “Spreadtrum” or “SCI” device should appear briefly.
- Q4. Will this process remove the Google Account (FRP) lock?
- No. Flashing the stock firmware will restore the original operating system, but it does not bypass Factory Reset Protection (FRP). You will still need to enter the credentials of the last Google account that was synced to the device.
