The WRT3200ACM is part of the wrt_ac_series, with 4 detachable antennas, and a faster dual core processor. It is a dualband, 802.11ac wave 2 (160MHz, no 80+80) capable device.
While only 1 revision of the hardware is listed, silently (around Nov 2017) the flash chip was updated in production causing earlier firmwares to be incompatible with newer devices.
If the firmware has become unresponsive and won't boot, chances are you can recover it easily due to the Dual Firmware partition layout, by switching to the alternate firmware.
For this reason, it is recommended to always keep at least one known good version of the firmware on either partition.
Switch router from primary to alternate partition or vice versa using any of the 4 below methods:

Some time around November 2017, Linksys silently updated the hardware for the WRT3200ACM, but did not change any version numbers or other identifiable labels. In particular, they changed the flash memory chip, which resulted in older firmwares causing bootloops on these new devices. This has since been fixed.
