thanks for the reply , 
when i first ran the system the wifi didn't work and neither did the bluetooth , then i installed this fix via cwm http://crewrktablets.arctablet.com/?wpfb_dl=1226 and the wifi works fine but the bluetooth don't , isn't there a fix for that?

ok keep me posted  , thanks

hello! 
thank you for the link , still the bluetooth isn't working after the fix you gave me 
and also the screen rotation was working perfectly and the g sensor don't so i had to try sensor fixes now the sreen rotation doesn't work and the g sensor does 

still the bluetooth isn't working 
for example i turn the tablet to the right and the screen turns upside down , also in games if i turn the tablet to left for instance the game detects mouvement down etc ... the problem is that the tablet doesn't detect correctly the movement i make 

i tried all the 7 sensor fixes and none of them worked , yes orientation isn't working . there's an app to test the accelerometer it shows a ball and it moves as you move the tablet , when a put the tablet on an horizontal surface the ball falls down as if i turned down the tablet , did you understand a bit the problem ?  
i'll open a terminal for the BT and posts the results in a few minutes
