seanbushong Posted March 24, 2011 Report Share Posted March 24, 2011 Hi i've searched the forums and i couldn't find a fix to my particular problem. When i turn my unit on the screen is black , the buttons light up for about 15 or 20 seconds then go black,but you can hear the fan running constantly. I tried doing a reset , that did nothing. Some one please help. Quote Link to post Share on other sites

Imo its a piece of junk get rid of it and buy a different brand (pioneer is junk/horrible customer support) Quote Link to post Share on other sites

Noel380 Posted March 26, 2011 Report Share Posted March 26, 2011 Its the same f90bt and f900bt are basically the same unit.... Quote Link to post Share on other sites
Noel380 Posted March 26, 2011 Report Share Posted March 26, 2011 Remember do not install sd card until ufter step 6. Up until then leave it out..... Once u finish step 5 insert the sd card and leave it inserted until u are ready to reboot to 3.0 update basically leave it in until u are completely done with all the steps. Hope it works Quote Link to post Share on other sites
Noel380 Posted March 26, 2011 Report Share Posted March 26, 2011 Sorry i meant do not install sd card until after step 5, when u do step 6 u need to have the sd card in. Quote Link to post Share on other sites
seanbushong Posted March 26, 2011 Author Report Share Posted March 26, 2011 ok when i do the upgrade (format) it reads the files up to 100% but it doesnt do anything else. no write image no reset unit Quote Link to post Share on other sites
Noel380 Posted March 29, 2011 Report Share Posted March 29, 2011 Hmm after it reads 100% itll take a minute or so then it will say RESET...... after u reset thats the step where u will need to go to test mode and rewrite the flash disk Quote Link to post Share on other sites
