Digma Optima 10 Z802 Firmware Flash File Download [Stock Rom]

Is your Digma Optima 10 Z802 tablet failing to boot, getting stuck on the Digma logo, or running so slowly that it’s become a chore to use? These are widespread problems for this model, frequently discussed by users on forums like 4PDA. The issues often stem from software corruption, malware infections that persist after a factory reset, or glitches from incomplete over-the-air (OTA) updates. Many owners report that the tablet becomes practically unusable, with constant app crashes and a laggy interface.

This procedure completely reinstalls the Android 10 operating system, erasing all the problematic data and restoring the device to its original, out-of-the-box state.

Quick Digma Optima 10 Z802 Firmware Flashing Instructions

Your tablet is powered by a UNISOC (Spreadtrum) processor, which requires the SPD Upgrade Tool for flashing.

1. Begin by installing the Spreadtrum USB Drivers on your computer and then rebooting your system.
2. Extract the firmware .zip file. Inside, you will find the firmware file with a .pac extension.
3. Launch the SPD Upgrade Tool. Click the “Load Packet” button (the single gear icon) and select the .pac file.
4. After the firmware is loaded into the tool, click the “Start Downloading” button (the play icon).
5. Device-Specific Step: Power the tablet off completely. Press and hold the Volume Down button, and while holding it, connect your tablet to the PC using a USB-C cable. The flashing will begin automatically.
6. Wait for the process to complete, indicated by a green “Passed” status in the tool. You can now disconnect and boot up your tablet. The initial startup may take longer than usual.

Troubleshooting & Optimization Guide

1. “Failed: NV data is corrupted” Error in SPD Tool
   This error means the flashing process failed to write the NVRAM/IMEI partition. This is often due to a poor USB connection or selecting the wrong flash mode. Ensure you are using a high-quality USB-C cable connected directly to a main USB port on your PC (not a hub). Rerun the flash process, but before starting, go to the tool’s settings (double gear icon) and make sure all partitions, especially “NV_W,” are checked for flashing.
2. Wi-Fi or Bluetooth Not Working After Flash
   This is a classic symptom of a hardware revision mismatch. You have likely flashed the Rev1 firmware onto a different hardware version of the tablet. The only solution is to find and flash the correct firmware that matches your tablet’s specific revision number.
3. Tablet Fails to Boot, Shows Only a Battery Charging Symbol
   If the tablet doesn’t boot after a “Passed” flash and only shows a charging icon when plugged in, the battery may be too deeply discharged to initiate a full boot sequence. Leave it connected to the wall charger (not the PC) for at least 2-3 hours before attempting to power it on again. If it still fails, you may need to re-flash the firmware.

Frequently Asked Questions

Where can I find the hardware revision number for my tablet?

The revision number (e.g., “Rev1” or “R1”) is usually printed on a white sticker on the back of the tablet. It may also be present on the original box. It is crucial to verify this before downloading and flashing any firmware.

Can I use this firmware to upgrade from an older version of Android?

This firmware is for restoring or re-installing Android 10, not for upgrading from a previous Android version. As this is the officially released version, no further major OS upgrades (like Android 11) have been made available by Digma for this model.

My tablet has 3GB of RAM, not 4GB. Can I still use this firmware?

No. The Digma Optima Z802 was released in several configurations. This firmware is specifically for the 4GB RAM / 64GB storage variant. Using it on a model with different memory specifications could lead to instability or a failed flash process.
