To my above statement ,
Just wanted to brag, for my first time I figured out how to Install TWRP, Flash CM 14.1, Install 7.1 GApps, and change my boot animations, for my very first ROOT and flash on my n900T Note 3 5.0.1 LP from T-mobile running on MetroPCS service and its stable and running great.
This process taught me to use ODIN , ADB sideload (basic commands), Flashify.
I bricked my phone 6 times doing this process but was able to to learn some valuable Information on TWRP recovery. Im so happy i took all the advice and made several backups to make sure i always had a way out.
First i used an MD5 file from Chainfire called CF-Auto root
After obtaining ROOT i backed up a recovery using TWRP 3.1, i made 2 copies 1 to my PC and one to my extSD card
I flashed lineage-14.1-20170426-UNOFFICIAL-hlte using adb and decided that it was pretty unstable and trying to update and make stable i ended up in a Boot Loop.
So i recovered back to stock recovery.img using TWRP and decided to try EffortLess+ROM-REV+8. I was amazed in how wonderful this ROM was putting me on 4.4 KK. I forgot how awesome KitKat os was and actually used it for a few days until i decided it just seemed to stock and wanted to try more. so i wondered around XDA for a day and found guides and links to install CM 14.1 7.1 N version for my phone and its pretty cool.
Boot animations were pretty easy after i figured out that samsung uses QMG files for start and end animations on there phones.
Anyways i found a new love for my cell phones and just wanted to state this is my first expirience in flashing and recovery and Rooting and now im an Addict.
If you have any questions on Rooting or Flashing your N900T i would be more than happy to Help with just the issues i ran into and overcame just by reading this forum XDA forum and google.
This is gonna be a whole new Hobby for me.
If you read this , Thanks!
