Hi, I'm developing a custom ROM for this device. I used your ROM and modified few bits in the system.img (using xubuntu, logged as root). I tried to remove NovaLauncher, here's my shell script:

mount -t ext4 -o loop system.img android_sys/

# remove nova launcher
ORIGTS=`stat -c "%Y" android_sys/app`
rm android_sys/app/NovaLauncher.apk
touch -d @$ORIGTS android_sys/app

umount android_sys/
 

Now after I low format the device and flash everything back (including system.img) the device starts fine and boots up, system loads up fine, Launcher3 is used (no prompt for a default launcher).

The problem starts with subsequent boots, I have noticed following unwanted behavior:

1. sometimes the device boots to the system, but the top statusbar and bottom navbar are completely hidden, it is not possible to drag down the statusbar or use SW keys (home, back, ...)

2. device is stuck in booting animation.

My q is: can NovaLauncher be removed from system.img as it seems that its removal is causing some issues? Or do you think it is something else that can be causing this odd behavior (e.g. mangled system.img ext4 partition?)

Thanks

Hi, after a very lengthy trial/error session, I found that the poblem was in a "corrupted" bootanimation.zip file. For some very odd reason, the tablet would end up in a boot loop if the animation was set this way:

1024 600 25
p 0 0 part0

And 50 png images in part0. Please note that the problem was not the png image format, but the number of images in an animation part. As soon as I used 53 images the problem was gone ... 

Anyways, thanks for this custom ROM, works flawlessly so far. I noticed that there was a particular battery drain reported by 'Mobile Standby' so I removed the telephony service (since it is a WiFi tablet only) and the system is still stable so far.

Dmesg attached. Hope it helps.
