[Galaxy Note 4 General] skypekestutiss:
N910F

Just want to give my experience rooting 5.1

my firmware N910FXXU1COI3

1 - I wanted to get root to remove all bloatware

2 - after all bloatware removed unroot and use original kernel and recovery

So what I have done:

1 - flashed this kernel: N910F-Stock_Kernel_XXU1COI3_Root_Enforced-PhilZ.tar via odin http://xdaforums.com/note-4/snapdragon-dev/n910f-android-stock-5-1-1-kernel-root-t3208778

2 - flashed twrp-2.8.7.0-trltetmo.img.tar via odin https://dl.twrp.me/trltetmo/

3 - downloaded chainfire BETA-SuperSU-v2.52.zip and saved to external SD card

4 - used twrp recovery and installed BETA-SuperSU-v2.52.zip http://xdaforums.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

5 - from play download titanium backup + root and removed all bloatware and other Samsung apk

6 - Open superuser and find full unroot then restart phone

7 - than restart again into twrp recovery and wipe cache partition + dalvik cache

8 - Than from original firmware my was 910FXXU1COI3 change end to zip and extracted recovery.img and boot.img

9 - Than the was problem as I cannt use them in odin I need to sign to md5 so - google search and I have found

MD5 Script in the xda forum http://xdaforums.com/showthread.php?t=2446269

10 - coped these 2 img to the same directory as MD5 Script and run ImgToTar.MD5.bat and I have 2 MD5 files boot.tar.md5 recovery.tar.md5

11 - then used odin I flashed firstrecovery.tar.md5 and later boot.tar.md5

Now phone runs original recovery and original kernel

why I unroot - maybe for security reason , I do think having root access and loading websites where tons of malware or opening files form somewhere is not really safe as superuser have root some clever master can go around this and can have root as well : ) But when on the phone none root who do get root ? phone itself will flash custom kernel maybe ? how this impossible I do not know

Whats the goal of removing/uninstalling bloatware if it can be disabled - yes 60 % samsung bloatware can be disabled but not all like samsung sync samsung tracking , like knox , and etc ,

I do not need to have on my phone any google remote , do not want to have any drop box sync or samsung sync etc ...

I m not using samsung email apk but it is running in background , Flipboard why the heck this is default ????? and getting notifications about news and can not disable This is why we need root

after all this work - does the phone works better ?

Yes feels more smooth as not run other apk in the background + it is programs what I need not what samsung or google want me to have for they money advertising or service

""""What I have noticed that after all bloatware removed and next step was to wipe cache partition + dalvik cache

my GSM signal jump to 1 bar more Do not know why? de- bloatware done something ?

I do think that wiping dalvik cache something happens , but if its help to have 1 bar more signal why not to try

When I drove home I have tested signal quality as I stream lot of net radio the spots where I have none 4G or H+ signal now I have signal maybe just 1 bar but I have signal H+ Where before phone make G connection and data signal lost """"" In practice it was like music playing that boom no music driving 3 min again music after 10 min drive again no music then after 3 min music and all road like this Now play music all road : ) :) :) :) :) :)
