Hello,

 

i am from holland.

sorry for my bad enlish.

 

i have a problem with my f900bt.

my device startup normal. i can use my sd card for music.

but i can't access the settings. the touch function isnt possible.

i have updated the device with the last firmware.

 

 

i think the device is missing some files.

 

1. can i reset the device to original manufactur settings?

 

2. how can i acces the test mode?

 

I hoop anybody can help me.

Have you done or tried to do any mods to the F90?

as for accessing test mode, you need to download some files from the site, do a search in the F- series section for boot disk.

As for the files, look at my signature.
