Eken+w70+v20+wm8850+firmware+link
Because the W70 and V20 are reference designs, you can sometimes use a generic WM8850 firmware from a different brand (e.g., Ployer MOMO or Chuwi V7). Search for:
generic_wm8850_800x480_4gb_20131120.img
This generic build usually enables Wi-Fi and touch, but you will need to calibrate the screen using the hidden *#*#3646633#*#* engineer menu.
Search within XDA for "WM8850 firmware". Look for threads from 2014 with attachments.

Why is finding an "eken w70 v20 wm8850 firmware link" so hard?
Between 2012 and 2015, websites like Eken.com, TabletRepublic, TechKnow, and AndroidTablets.net hosted thousands of firmware files. Today, those domains are dead or restructured. The main reasons for broken links include:
However, a few dedicated communities have kept the flame alive. Below is the most reliable path to find your firmware.
Finding the correct firmware for generic tablets powered by the VIA WM8850 chipset can be a challenge, especially for specific models like the Eken W70 (V20). Using the wrong build can lead to a "white screen" or a non-functional touchscreen.
This guide provides the necessary links and steps to restore your device. Firmware Download Links
Depending on your hardware revision, you may need one of the following: eken+w70+v20+wm8850+firmware+link
Official Eken W70 V20 Firmware (Android 4.1.1): Download Link (Note: Use a verified mirror if the official Eken site is down).
Universal WM8850 Uberoid Tool: Many users prefer the Uberoid custom ROM for better performance and compatibility. You can find the latest version on the TechKnow Forum. Device Specifications
Before flashing, ensure your device matches these specs to avoid "bricking": Processor: VIA WM8850 (Cortex A9) 1.2GHz - 1.5GHz. GPU: Mali-400. Screen: 7-inch Capacitive, 800x480 resolution. RAM: 512MB DDR3. How to Flash Your Eken W70 V20
Flashing this device is done via a MicroSD card. Follow these steps:
Prepare the SD Card: Use a high-quality MicroSD card (8GB or less is recommended for compatibility). Format it to FAT32.
Extract Files: Unzip your firmware package. You should see a folder named FirmwareInstall and a file named wmt_scriptcmd.
Copy to Root: Move both the folder and the script file to the root directory of your SD card.
Power Off: Ensure your tablet is completely turned off and has at least 50% battery.
Insert and Boot: Insert the SD card into the tablet and power it on.
Automatic Install: The WM8850 bootloader will detect the script. You will see a green progress bar on the screen. Do not touch the device during this process. Because the W70 and V20 are reference designs,
Remove and Reboot: Once the screen says "Please remove SD Card," pull the card out. The tablet will reboot automatically into the new firmware. Troubleshooting
Stuck at Logo: If the tablet hangs at the Eken logo for more than 10 minutes, try a different SD card or a different version of the firmware.
Touchscreen Not Working: This usually means the firmware uses a different kernel driver than your specific V20 revision. You may need to try the "Changeboot" tool included in Uberoid packages to swap the touchscreen driver.
Do you have the exact hardware version number found on the back of your tablet or on the internal motherboard?
The Eken W70 tablet, specifically using the WonderMedia WM8850 chipset and V20 build (often marked on the PCB or screen, such as "W70_V20_20121114" or similar late 2012 dates), commonly requires specific WM8850 firmware files to be flashed via SD card. Key Information & Files: Firmware Source:
The most commonly referenced, working, and rooted firmware for Eken WM8850 MID tablets is available via a detailed guide by CNX Software File Needed:
Specifically look for firmware files designed for WM8850 (e.g., W70-1.1.0-2012-08-15.rar, or specifically for V20 boards) that include a FirmwareInstall folder and wmt_scriptcmd Rooting/Modification:
The provided firmware often includes rooted images, and additional rooting tools like RootBurner are specifically designed for this chipset. Flashing Method: Format a Micro SD card (FAT32). Extract the firmware files, copying the FirmwareInstall directory and wmt_scriptcmd to the root of the SD card. Insert the card into the powered-off tablet.
Turn on the tablet, and it should automatically enter the update process.
Once finished, remove the SD card and delete the files to prevent re-flashing upon reboot. What the file should contain: Why is finding
Note: As this device is from 2012, many original Eken site links may be dead, making the archived links on tech forums (like CNX Software ) the primary source. wondermedia wm8850 | Early Bird Club
For the Eken W70 V2.0 tablet (powered by the VIA WM8850 processor), the most effective way to restore or update the device is using a specific bootable microSD card method. Because this hardware is legacy, many original manufacturer links are no longer active, but community archives provide the necessary files. 1. Recommended Firmware & Links
The Eken W70 is often interchangeable with "WM8850-MID" generic tablets.
Stock/Rooted Firmware: Version v1.1.0 is widely used for stability.
Universal Uberoid: For a more optimized experience, the WM8850 Universal Uberoid V3.1 (Jelly Bean 4.1.1) is a popular community alternative.
Archive Sources: You can find verified backups on the Internet Archive or through dedicated hardware forums like Android Tablet Forum. 2. Key "Feature" for Installation (The SD Method)
The most critical feature of this firmware is its auto-installer, which triggers during the boot sequence if the correct files are present on a microSD card. Format a microSD card to FAT32.
Extract the firmware package. You must have the FirmwareInstall directory and the wmt_scriptcmd file in the root of the SD card.
Configuring for V2.0: If your screen alignment is off or the touch doesn't work, navigate to FirmwareInstall/config. Look for a file starting with a + sign. To match your specific hardware, remove the + from the current file and add it to the start of the configuration file that matches your specific model (e.g., +MID7_8233...fwc).
Flash: Insert the card while the tablet is off, then hold the Power button. The installation should start automatically and prompt you to remove the card once finished. 3. Troubleshooting "Bricked" or Frozen Units
Reset: If the device freezes after an upgrade, remove the battery (if possible) or hold the Power button for at least 8 seconds to force a hardware reset.
Clean Up: After a successful flash, delete the installation files from your SD card; otherwise, the tablet will try to re-install the firmware every time it reboots.
