I did the software bypass on my X910Bt a long time ago. If everything has been fine, till out of th eblue I saw something about a warning with the parking brake and now it endlessly boot loops, splash screen to black, splash screen to black. However, randomly it will start working except for the gps will not show any position. If I had selected the radio to play previously, it will start playing the radio during the splash screen but then stops and goes through the boot loop.
