MK2.5S and 3.5.3 Firmware = Infinite Loop of load/unload filament
I just upgraded my MK2.5S (upgraded from 2S with kit) from firmware 3.5.1 to v3.5.3 The update went fine but now when I try to print the bed leveling completes as usual, but then it gets stuck in an infinite loop of "unload filament", then "load filament". It will never start printing the part. This is the same behaviour with files that worked fine in the past and newly created gcode files.
I guess I can downgrade to 3.5.1 again, but has anyone seen this issue with the new 3.5.3 firmware?
Thanks

Bad to answer your own question, but I installed the 2.5S firmware based on the fact that I bought the "Original Prusa i3 MK2/S to MK2.5Supgrade kit" but it seems like I have to use the 2.5 (no "S") firmware. Confused but fixed by using the 3.5.2 firmware which is the latest for the 2.5.

Thank you! I am seeing the exact same issue, having upgraded my MK2.5s to 3.5.3, using prusa3d_fw_mk25s_3_5_3_RAMB013a_en-es.hex
In addition to the unloading/loading loop, when I attempt to recalibrate XYZ, it gets to the point after I have raise z all the way to the stop and it starts lowering to look for bed sensor 1 of 4. It decends to the bed and then stops and says xyz calibration failed.
I am going to try MK2.5 3_5_2 firmware next.

RE: MK2.5S and 3.5.3 Firmware = Infinite Loop of load/unload filament
I have the exact same issue on my newly upgraded 2.5 to 2.5s, firmmware 3.7. I have tried to flash back to 2.5 firmware 3.7 and it tells me my filament sensor is (N/A) not availeble. flashing back to 2.5s firmware 3.7 makes filament sensor seem to be fine but i get infinite loop change filament unless i turn sensor off in settings, any ideas?

Ugh. I just completed a 2/S to 2.5/S upgrade, flashed 3.7.2 firmware and I am also now stuck in the infinite filament unload/load cycle.
I am pretty confident that I flashed the correct firmware.
