Hello All,

Hope you can help with this!

When I wake my rooted Tab P7500 from sleep the display is a jumbled mess of flickering lines:

I recently acquired this for free from family and decided to root since it was running so slowly (4.0.4). My steps:

- Rooted the device
- Installed TWRP
- Installed Nameless ROM (4.4.4) for P7500
- Installed GApps

At a certain point (I think when I was rebooting into recovery mode after installing TWRP), I had the issue of the rolling recovery screen. I found and followed the instructions to fix this (forum.xda-developers com/showpost.php?p=27830023&postcount=41). It worked. But then later I noticed the issue with the messed up post-wakeup screen. Not sure if these 2 are related.

I tried a couple of different things after doing some research - flashing a different kernel and a US bootloader. Nothing worked.

Other than the display problem, the tab runs great. Sure hope that I can fix and use it!

Thanks for reading and for any advice!
