Zoom H4n 1.72 -or lower- version needed urgently :/

Hi all.
Since i've updated my firmware with 1.90 , my precious zoom h4n is not working properly.. only way for me is to get back to an older version. I m writing this in hope for an help. Thanks

How did you establish that regressing to older firmware would fix the H4N? Did you try to reinstall the 1.9 firmware?
