Click the within the software interface. Power off your target UMS512 device completely. Hold down the Volume Down button (or both volume keys depending on the OEM implementation) and connect the USB cable from the PC to the device. Step 4: Monitor the Progress
Plug the USB drive into the primary USB OTG port of the device (usually labeled USB 1). Trigger the Update:
Software-based recovery via USB is no longer possible. The SPI flash memory chip on the UMS512-1H10-NATV board must be physically desoldered or hooked up to an EEPROM programmer (such as an RT809F or CH341A) to flash the original partition binaries directly onto the chip. Summary and Best Practices ums512-1h10-natv firmware update
A: You used a standard UMS512 firmware. Re-flash with the NATV specific version. The NATV includes a patched gt9xx_driver.ko file. If you cannot find the NATV firmware, you must manually compile the touch driver—which is unbelievably difficult for amateurs.
