N910G restarts multiple times after flashing with stock rom from sammobile

Hello,

I have been using my N910G with DN5 rom by Dr.Ketan. Later when I had issues like device lagging, I flashed it with the stock rom from sammobile which is the australian version. BOH4

Now, everything seems fine, but the device restarts on its own, sometimes just gets stuck and I have to remove the battery and start the phone again. Most of the times, it gets stuck, vibrates twice, immediately restarts.

How else can we fix this issue? Please help!

Apply multiple themes?

I just installed this app 2 days ago. I like all the themes that are available, but most themes are only one screen. Is there a way to download multiple themes and have them all applied at the same time using multiple pages? It doesn't seem like it's possible, but I thought I would ask before switching launchers. Thanks.
