Hi, I'm ZShock, and I'm new. This is what happent to me by beeing stupid!

Please, excuse my bad english, my 1st language is spanish.
Well, here comes the problem. I have a MP4, exactly like this picture uploaded by someone

The problems is, I upgraded with the incorrect upgrade and I didn't find MY Lotus Flower Firmware. Currently, I used a firmware, and seemed to work, but instead of opening the volume menu, it sets the volume down. So, in fact, my problem is, I need the Lotus Flower Firmware 3.5.37, if possible.
Thanks for your time, ZShock.
