where to get old firmware for s5? PSA dont install 5.5.12!

i recently purchased an ultimaker s5 back in january and its been printing fairly consistently for the past couple of months. recently i attempted to do my first large print on the machine (7days) and decided i should update the firmware to the latest version 5.5.12. a few days into the print i got a err998 error and the screen stopped working. after talking to technical support they informed me that this is a common bug with the new firmware (which begs the question why release it then?). my printer was going to run out of filament mid print and since i couldnt access the ui of the printer i basically had to cancel the print after days and over half a roll of filament spent. the technician recommended i install an older firmware 5.2.11 that is actually stable but i cant find anything but the release notes on the website. does anybody know where i can get older versions of the s5 firmware to download? tech support hasnt been very helpful.

that's a shame the 5.2.11 can be found here: http://software.ultimaker.com/releases/firmware/stable/5.2.11.20190503/um-update-5.2.11.20190503.swu

 

Or for unbricking purposes from sd card http://software.ultimaker.com/releases/firmware/stable/5.2.11.20190503/recovery-5.2.11.20190503.img

 

We are working on the ER998 occurrences and will introduce software to better track these kinds of problems!

thank you @robinmdh i will try installing the older update. my guess is the newer firmware was optimized for the latest s5 model since they have two different versions of the firmware. that and that the update only disabled the use of my screen and didnt effect the part of the printer that actually handled the printing. i will try to install the older version and do a test print before attempting another large print.
