I installed the 'Eddict Player' app for Shanling devices on my Pixel 8 Pro, and until yesterday I have tweaked the low/high gain options and low-pass filter options but could not eliminate the tick noise I'm experiencing. So I decided to try rewriting the original ver 07 firmware on my UA3 later...

Actually, my issue with the version 09 is random small tick noise during playback, connected to Pixel 8 Pro. I understand there are so many different Android phones so its very hard to satisfy all those different OS modifications! I concluded that I would just be happy with the older ver 07...

Is it safe to roll back to the old firmware 01.01.07, using the writing tools included in the zip file of 01.01.07? I updated my UA3 to the latest version 01.01.09 but after that I am experiencing some problem. So I'd like to try the old firmware if writing the old .hex file doesn't break my UA3.
