Maybe someone here can help me?
I got IHIFI 812V2, and at first was extremely happy with its sound. And then I did something really stupid and upgraded the firmware using this file (which is supposed to be for both 812v2 and 960): http://www.i-hifi.com/hd/960/ihifi164.rar
Now, after the upgrade, it seems like something is wrong with it. Everything is working, but it just sounds wrong. The sound is clean, but thin, and the highs are far too excessive, to a degree it hurts my ears listening to it (both with my earphones and headphone). I wish I could revent back to the original version, but I cannot find it. Tried to contact them, but faced some language barriers.
Did anyone else here faced the same problem? Or maybe others here are just smarter than me and know better than doing unnecessary firmware updates? Does anyone happen to have a file with the older firmware, or at least can tell me whats the version number you your device?
