Hi.

I have a telecom new zealand i9505. I attempted to install a custom recovery but I'm not sure if it worked. I do have a recovery mode I can boot into but it doesn't have many options and I assume it's the stock Samsung recovery. My phone is currently running Android 4.3 but doesn't autoupdate bc I now have a modified the recovery.

Can someone suggest either
1. What stock rom should I flash to. Do I have to flash to another stock 4.3 rom using odin or can I flash a 4.4.3 rom? If I flash using odin can I use the autoupdate feature under settings?

2. Is there a fast stable rom that has built in auto updates without having to worry about flashing and backing up etc.

The reason I want to update is.
1. The phone is sometimes sluggish.
2. There was a Google update that caused a bug whereas every time I pah home button it askes which home screen and it will not remember the defaults and the ONLY solution was to uninstall the updates which means I don't have Google now anymore.

Thanks
Kiwi
