Firmware dump for the TP-Link TL-MR100 4G LTE router, sized for a 4 MB flash chip, with the name marking it as checked and working. The archive is meant for restoring a bricked unit by writing the image directly to the SPI flash with a programmer such as a CH341A. Read and save the original chip contents first, since the dump carries its own calibration and MAC data. Confirm the hardware version on the router label matches, and that the image size fits the 4 MB chip before writing.
