Firmware dump for the TP-Link TL-MR100 4G LTE router, marked OK in the name, suggesting it was verified working. The RAR is 3.82 MB. Router dumps are generally written directly to the SPI flash with a programmer to recover a unit stuck in boot loops or bricked by a failed update. Read and keep the original chip contents first, since calibration and MAC data are stored there, check the hardware version on the label and confirm the image size matches the chip.
