Android Tablet Software Recommendations Please....

I am constantly encountering 'bricked' tablets and only recently came across a Nexus 7 1st Gen 32Gb. It was locked on the Google Logo but I sorted it with the usual volume and power button combinations. I do get them however when that simply will not work and I see all the different versions of software out there to "flash" or reset these type of Nexus tablets. Can I ask which particular software the readers on here would unhesitatingly recommend please ?? I would really like to be able to delve further into android tablet problems and hopefully solve them. Many thanks for any advice given...much appreciated.

root and rom recommendations

Hello dear forum!
After my nexus 5 broke, I decided to buy the cheapest phone in a similar spec range, and ended up with a used galaxy s4 (i9505). But I really wanted to keep the stock android experience as good as it gets, so my questions are simple: How do I root and install a custom recovery (if needed), and what would be the best rom (if possible with easy updates)?
Also on a side note, is it normal for the screen, when the brightness is set to minimum, to look really weird (i.e. text fades) when scrolling?
