How to Flash Stock Firmware

To restore your Archos Alba 5, you will use the SPD Upgrade Tool on a Windows PC. First, ensure you have correctly installed the Spreadtrum SCI USB drivers. Launch the tool, click the single gear icon (“Load Packet”), and select the .pac firmware file. Click the play icon (“Start Downloading”). Power off your phone completely. Finally, press and hold the Volume Down button while connecting the phone to your computer with a USB cable to initiate the flashing process.

Device-Specific Troubleshooting for Archos Alba 5

• For 4G (SC9832) Model ONLY: This firmware is specifically for the 4G version of the Archos Alba 5 which uses the SC9832 chipset. It is NOT compatible with the older “Alba 5 3G” model which uses an SC7731 chipset. Flashing the wrong firmware will brick your device.
• Tool is Stuck on “Checking Baudrate”: This is the most common error when flashing Spreadtrum devices and it indicates a driver issue. Uninstall and reinstall the Spreadtrum drivers, use a different USB port (a main one on the back of your PC is best), and try a different USB cable.
• Entering Flash Mode: To start the process, you must hold a boot key. For the Archos Alba 5, this is typically Volume Down. If that doesn’t work, try holding Volume Up while connecting the powered-off phone.
• “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. 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. My Archos Alba 5 is completely dead. Will this firmware fix it?

Yes. If you have the 4G model and the cause of the dead device is corrupted software (a “hard brick”), then flashing this official .pac firmware is the standard procedure to unbrick it.

Q2. What is a .pac file?

A .pac file is an all-in-one firmware package for devices with Spreadtrum (now UNISOC) chipsets. It bundles all system partitions (boot, recovery, system, etc.) into a single file for easy flashing.

Q3. The flash tool doesn’t detect my phone. What’s wrong?

This is a driver issue 99% of the time. Ensure the Spreadtrum SCI drivers are installed correctly. Open the Windows Device Manager before connecting your phone; when you connect it while holding Volume Down, a “Spreadtrum” or “SCI” device should appear briefly.
