[Q] Galaxy note 3 update kit kat Help!

My galaxy note 3 tmobile Version was recently rooted. After I rooted it, I noticed that a software update was available. After research, I realized that you cannot update the software while your device is rooted. I tried using Xposted and Wanam, but it didn't suffice. Is it possible to flash an updated rom such as c-rom onto my phone? Or would that end up in a soft brick? I was hoping to install c-rom 4.4 onto my phone but its been taking a while to load up. It shows the c-rom logo, but I get inpatient after about 15 minutes of waiting. So I end up going into recovery. Is there another way I could update and keep my root?
Help would really be appreciated
Anyone?
I use stock rom and update with Mobile Odin . I Keep root with it

JIAYU S3 - 2GB, ANDROID 5.1.1 Official Problem

Hi , everyone!
Hope you guys can help this noob here.
I installed the android 5.1.1 on my jiayu s3, from jiayu.es using sp_flashtool.
That part went fine
The problem is, I don't know what to do next.
I mean, I tried to install gapps via recovery but I receive a message saying
"INVALID OTA PACKAGE, MISSING SCATTER"
so I am with 5.1.1 but without root or gapps.
My phone is useless
Probaly what I am not seeing is extremely simple but I really don't know what to do and apreciate any help.
Thanks in advance.

G901F TWRP and CM13 install/flash help needed

Hello all,
I have a Samsung Galaxy S5 Plus (SM-G901F) and after some research I wanted to install TWRP and CM 13, I downloaded G901F_TWRP_v2.8.5.0.tar from here because I thought that was the one I needed to flash but Odin says "Can't open the specified line. (Line 2012) I noticed that TWRP 3.0 is also released so don't know which one to pick which works and also don't know which CM 13 to pick to install, I'm not really good at these things so I'm looking for someone who can help me through everything step by step so I have it running smoothly and don't mess up or brick my phone, at the moment I have rooted my phone and am using the stock firmware from Samsung itself. Hopefully someone can help me with this?
Thank you in advance
