So my main concern is is there a way to downgrade this kitkat into jellybean? Put aside note 3 for now. Does it work on other phones as well? Because i really dont like the new kitkat and i want to go back from 4.3. Yeah yeah i did some research regarding to this because of the new bootloader. I really hope that we can be able to downgrade.
Yeah dude, I'm so totally in agreement with you. My note 3 was fast, snappy, fluid, and just awesome all around till I upgraded to kit kat lol.
After using some google-fu, the reason why we can't downgrade from KK is because the qfuse was blown/tripped while updating. The qfuse is a physical part of the mobo and when its blown, its just not feasible to downgrade anymore I think. Yes, Sammy intended to blow/trip the qfuse.
Many reported that after updating, the sdcard could not be read, low or no signals, sluggishness, unexpected reboots, endless loops, battering draining rapidly, and so on. The solution was to do a factory reset which ended up fixing a lot of the issues. I reset my phone twice after updating and none of the problems mentioned happened to my phone.
However, I did experience that my phone was not as snappy and fluid as it was with JB. My 4G/LTE signals were very weak and my apps did not open as fast before. My banking app took forever to open. I was so pissed off. Entering my pin at the lock screen is sluggish and other things that I started to notice really disappointed me.
I called my carrier to complain about the update and told them my signal was always weak, peaking at one or two bars. The rep reset my signal connection and its okay but not as great as before. My apps open up a bit faster now.
I didn't know if you realized that Sammy took kit kat and customized the hell out of it. Its not Google's fault or that kit kat sucks. Place the blame on Sammy because I don't think the custom KK update was fully tested. It was more like it was rushed imo.
I won't be able to downgrade or root.
