In step 10 , The oldin program keeps FAILING . How do I get the oldin program to pass so that I can root my device . I appreciate your help and thanks in advance.
Look up user Kevin quintana (kevinwithtecg) on youtube. He has a step-by-step process to revert the phone to 4.4.2, root it, then upgrade back to 4.4.4 while maintaining root. I used it and it works perfectly. It will however wipe your phone clean (contacts, apps, etc.), so save those and reup.

what is missed after Note5 unroot!

Hello,
I knew that if I root my Note5 (N920C) I will lose Knox and Samsung pay.
I've a question, If I revert to the original firmware shall I get back Samsung pay and knox?
generally, If I installed back the original firmware, is everything will back to normal or some issues would happen??
if there are issues after unrooting and installing the stock firmware, please list them all.
thank you for your support.
Samsung pay is gone. Knox will always be 0x1.you will have no deepsleep.

Hi ,
in short , if you flash your latest official stock Rom
You obviously loose root .!
Secondly ,if Knox is tripped it stays like that ., permanently
It's what they called a "e fuse " that was tripped.
(Nothing you do ,can will fix knox ,Only Samsung can and the most probably won't )
Also if you unroot chances are that your phone won't "deep sleep" ?
Samsung Pay ,i don't know.
Good luck
Thank you guys. the stock firmware is pretty good already. there is no good reason for rooting

Plan to root my tab s2

Hi all !
I have decided to root my tab s2 to gain access to system to modify parameters to disable add user option in notification. I see no other working option.
Request to help me with the required tools and guide to root. Will it be possible to update to nougat after I root ?
Is it possible to root the device and stay on the same andriod version ? I have previous rooted my other phones including pantech burst and samsung wave 2 but not able to find a complete guide for tab s2 SM-T715
Thanks a lot !
Yes, it possible to root the device and stay on the same andriod version. Matter of fact, once rooted you should disable OTA updates for thyat can break root and your device.
You could update the OS manually via TWRP.
But first and for most, you had better make a system backup before tinkering about.

Moreover, TWRP can give you temporary root access.

Root Samsung Note 8 with android 9 assistance

Hello everyone,
I am a complete noob when it comes to rooting and I am requesting assistance. I've searched the internet and looked through many posts/threads here on the xda forums.
I recently accidentally factory reset my phone (like a dummy) and lost all my photos/videos. I am trying to recover the files from my phones internal storage using a deep scan recovery but I cannot do so without rooting my phone. I've used KingRoot, KingoRoot, Magisk, TWRP, Odin, etc to try and root my phone.
My phone is a Samsung Note 8, Model SM-N950U, Android version 9, basebad version N90USQU8DUE1.
I would greatly appreciate any assistance/guidance!
