Activate usb debugging, and use adb logcat to see what is generating the reboot.

I do not think I know something, because suddenly closes tablet and I think that data is lost when they give restart.
I tried the application on you but I do not see anything in that log.

What other choice do I have?

Flash back the stock firmware again, do a factory reset.

I did this 2-3 times no result
I changed the original firmware arnova with firmware created by Doman 75 (Custom Firmware 4.0.3 V1.5 with Win8 Metro UI) was installed without errors but I have the same problem when I try to wake up from  sleeping the tablet ,in  about 4 seconds will restart automatically.(no eror,no mesage !)

Thats why i said, enable usb debugging, and use adb logcat, because there you can see erorrs that do not appear on the screen of the tablet.

Hi globula_neagra

After I struggled all day to find out what generates the problem, I managed to find these
problem was generated by asigment button, which from what I saw was wrong
I researched on the internet and with a little program ButtonRemapper - Beta v0.2.4, I was able to fix the problem.

From what I saw this program on-off button and a IIa command was assimilated after I canceled the second order everything returned to normal.
Now I can wake the tablet from sleep position without having to restart itself.
Know that your choice is very good. Thanks for your help.
all the best

Hi Daniel,

as I have exactly the same problem and downloaded ButtonRemapper to fix it ...

Could you please advise, what exactly you did with this App?

I assume with on-off-button you mean the "Power"-button, correct?

Did you assign a new command ("wake" or "wake-dropped"?) or just started the App without changes (+ reboot)? The App complained that I don't have full root access - do I need this and how can I "root" the Tab?

Thanks a lot,

Jens

Hi jhartwig

My recommendation is not to make more changes than necessary software. (I have not tried the rest of the options)
The only option I changed it "wake" and then I give restart the tablet.
I honestly do not know if you must have root access. but worth trying you have nothing to lose.
