All your files, photos, and contacts on the internal storage will be permanently deleted during this process.

To prevent interruptions, ensure the tablet's battery has at least a 50% charge before you begin.

Windows PC & USB Cable:

This procedure requires a Windows computer and the tablet's micro USB data cable.

Tablet Not Detected by PC:

If the flash tool doesn't respond when you connect the tablet, it's a driver or connection sequence issue. Re-install the VCOM drivers. Then, click "Download" in the tool, press and hold the Volume Down button on the tablet, and then connect the USB cable. This often forces the device into the correct flashing mode.

"PMT changed for the ROM" Error:

This partition error can occur if the existing software on the tablet has a different layout from the firmware you are flashing. To fix this, change the flashing mode in SP Flash Tool from "Download Only" to "Firmware Upgrade" and try again. This will erase all data.

"S_BROM_DOWNLOAD_DA_FAIL" Error:

This error can sometimes be caused by an incompatibility with the Download Agent (DA) file included in the tool. Using a newer version of the SP Flash Tool, which contains an updated DA, can often resolve this issue.

Stuck on Archos Logo After Flashing:

If the flash completes but the tablet won't boot, you must perform a factory reset. Power off the device, then boot into recovery mode (usually by holding Power + Volume Up). In the recovery menu, select "wipe data/factory reset," and then reboot.

❓ Frequently Asked Questions (FAQs)

Q1. Can I use this firmware to upgrade my tablet to a newer version of Android?: No. This is the official Android 6.0 Marshmallow firmware, which was the final OS version officially released by Archos for the 80 Oxygen model.
Q2. I’m getting a “BROM ERROR” in SP Flash Tool. What should I do?: BROM errors typically indicate a communication failure between the PC and the device’s chipset. The most common causes are incorrect VCOM drivers, a faulty USB cable, or an unstable USB port. Re-install the drivers, try a different cable/port, and ensure the tablet is completely powered off before connecting it.
Q3. My tablet’s Wi-Fi or Bluetooth isn’t working after flashing. What’s the fix?: This can happen if the NVRAM partition, which stores your device’s unique MAC addresses, is corrupted. This is often caused by using the “Format All + Download” option. Flashing again using “Download Only” mode is the first step. If the issue persists, it may require an advanced NVRAM repair or could indicate a hardware failure.
