I am currently having a big trouble with my hp touchpad, it was working very well until my dad asked me to try something with the bluetooth.
I just actived it from a gadget (not from the menu) and since I push the button, my touchpad restarted the cyanogen9 then when he finishes restarting, it do it again and again as a loop.
It seems that it all started after pushing the activation of Bluetooth :s
I actually tried to instal other version of cyanogen9 (I was on the version : cm-9-20130929-NIGHTLY-tenderloin, and now I am on cm-9-20130714-NIGHTLY-tenderloin but the result is the same since the Bluetooth is still activated.
I also tried to do a wipe cache but since that my touchpad just stay on the loading screen of cyanogen9...
Thanks for your help.
