Cannot reboot into Android after installing Picuntu

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Flash kernel into recovery
2. Reboot to recovery from Android
3. Reboot from Picuntu

What is the expected output? What do you see instead?

Device should reboot into Android but instead it always reboot to Picuntu. I 
have to flash original recovery to reboot to Android.

What version of the product are you using? On what operating system?

I'm using a MK808 with Finless 1.6. I tried RC2.2 kernel and RC3.

Please provide any additional information below.

After flashing original recovery, I get the "dead" Android on the screen. I 
manage to boot Android after unplugging and plugg
ing a few times.

i have meet this issue before,the reason is from andriod "FIRST" reboot to 
picuntu, you must select "reboot to bootloader" not "reboot to recovery",you 
can reflash recovery image(this is liunx kernel) and try again.

you can use command "su" and "reboot recovery" or 
you can use another reboot app, davidjr621.rebooter_1.6.0.apk
with this , if you reboot to recovery, you don't have any problem to reboot to 
android.
this solution work on my cx803/v8
