croqui, don't worry. Sony software stay installed . It's like from the retail box.

So here's a step by step guide for those who are faced with the problems (freezes player, the long pauses when switching tracks, etc.) after updating to firmware 1.10. Video - http://www.youtube.com/watch?v=40Fx08jaqF4&feature=youtu.be 1. Copy somewhere, all your songs, movies, etc. from the...

Rednuht I was in the same boat but now everything ok. First, backup or copy all your data to safe place. Go to Settings-Backup & reset-Factory data reset. Then I installed all my software again and update sony media player. :-)

It's strange.. Usually I listen without EQ. I have only one mark against - dynamic normalization. All other effects are disabled.

Yes, the bass level is increased from 0 to +10, or decreases from 0 to -10. I have a Sony Media Player version 1.4.2 and the latest firmware 1.1. Maybe you have another version?

Graviton, just listening to your song, and I did not get any distortion, even if CLEARBASS +10. I use the player with the JVC HA-FXT90 + Comply TS-400.

I also have a serial number of my F806 and there's no problem with upgrade. I bought it from http://www.computeruniverse.net/ in retail box.

Search in GooglePlay - Media players for WALKMAN (12.12.12 )

Migou67, I just turned on the wi-fi and went to PlayMarket and the application will automatically update. But here's link - https://play.google.com/store/apps/details?id=com.sony.walkman.mediaplayers&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5zb255LndhbGttYW4ubWVkaWFwbGF5ZXJzIl0.

Recently upgraded Sony Media Player to version 1.4.2. via Wi-Fi. Probably fixed a bugs.

Communicated through a chat with Sony tech support and they recommend - when the player is turned ON to clamp reset button on the back of the player. Waiting for reboot and try. After this, a period of 3 hours, the error with the player and switch tracks not noticed

After a successful upgrade to the new firmware, stock audio player 3 times hung. Previous never freezes for 2-month use. It's sad.
