If you are searching for this exact string, you are likely trying to revive a "bricked" device or find a compatible firmware update (ROM) for a generic 7-inch tablet. Breaking Down the Technical String

To understand how to find the right software, you have to decode the hardware components listed in your keyword:

WM8850: This is the VIA WonderMedia WM8850 processor. It was a popular, low-cost ARM Cortex-A9 chip used in thousands of "no-name" Chinese tablets.

MID7: Stands for "Mobile Internet Device 7-inch." This confirms the screen size.

Puzhi / W01 / 8223: These are internal factory codes. "Puzhi" is often the name of the original design manufacturer (ODM), while "W01" and "8223" refer to the specific PCB (Printed Circuit Board) layout.

FT5206: This is the FocalTech FT5206 capacitive touch screen controller. This is the most critical part—if you flash a ROM with the wrong touch driver, your screen won't respond to finger presses.

W70 / WMC1579: These are model numbers often found on the sticker inside the back cover or in the "About Tablet" section of the settings.

UPD: This indicates a request for an "Update" or a .upd firmware file extension used by the WonderMedia flashing tool. Why is this Firmware Hard to Find?

Generic tablets (often called "white-label" tablets) were manufactured in massive quantities with slight variations. Two tablets might look identical on the outside, but if one has an FT5206 touch controller and the other has a Goodix controller, their firmwares are not compatible. Flashing the wrong one will result in a "dead" touch screen or a tablet that hangs at the boot logo. How to Update or Restore Your WM8850 Tablet This string identifies a specific firmware build for

If you are looking for the firmware (the "upd" file) for this specific configuration, follow these steps: 1. Identify the Exact PCB Version

Before flashing anything, you should ideally open the tablet (they usually clip together without screws). Look for a string printed directly on the green circuit board. It might look like W01_8223_V2. This is the only way to be 100% sure the firmware will work. 2. Locate the Firmware

Search specialized archives like XDA Developers, Slatedroid, or TechKnow. Look for "WM8850 Universal Uberoid" or "WonderMedia WM8850 Firmware."

Note: Because these tablets are legacy devices, many original download links (like those on Mega or MediaFire) may be dead. You may need to use the Wayback Machine or look for re-uploads on forum mirrors. 3. The Installation Process

Prepare a MicroSD Card: Format a card (8GB or smaller is best) to FAT32.

Copy the Files: Place the firmwareinstall folder and the wmt_scriptcmd file into the root directory of the SD card.

Boot into Flash Mode: Turn the tablet off. Insert the SD card and turn the tablet on.

Automatic Update: The WM8850 bootloader should automatically detect the SD card and begin a blue or green progress bar screen that says "Upgrading."

Remove and Reboot: Once it reaches 100%, remove the SD card and the tablet will reboot into the new OS (usually Android 4.0 or 4.1). Common Troubleshooting

Touch Screen Inverted: If the tablet boots but touches are mirrored, you have the wrong env settings for the FT5206 controller. You can sometimes edit the wmt_scriptcmd file to change the touch orientation.

Stuck at 0%: Your SD card might not be compatible. Try a different, older card (non-SDHC if possible).

No Power: Ensure the tablet is plugged into a wall charger. These devices often have degraded batteries that cannot provide enough voltage for the flashing process. Conclusion

3. Anatomy of the Board (PUZHI W01 & 8223)

  • PUZHI W01: Puzhi Industrial Co. was a major ODM for budget tablets. The "W01" is a 2-layer PCB design notorious for:
    • Weak voltage regulators (overheats easily).
    • Shared ground planes causing "ghost touches" on the FT5206.
    • JTAG pads exposed (good for hard brick recovery).
  • 8223: Most likely the LCD driver IC (e.g., ILI8223 or HX8223). This chip drives a 7-inch 800x480 (WVGA) or 1024x600 panel. Note: If this fails, the screen stays white but backlight works.
