[Samsung Galaxy S7 Questions and Answers] Yotitchy:
Hi everyone !

For noob user like me : root S7 = risk to no more working knox samsung app : mainly samsung pass / secure folder. Sad i've didn't seen that before rooting -_-

For others : I prefer to open a new thread, because i've read many post about knox problem or only pass or only secure folder after root... people saying yes, no, work, don't work, update, offical stock rom, snapdragon, magisk, or nothing :/

I got a S7 G930F from France (exynos?), now model version show g930fxx4esc5, i've try root, pass, [...] and no more knox app.

- I've seen index-samsung-galaxy-s7 thread, put oem unlock, followed CF-Auto Root link http://autoroot.chainfire.eu/

> alert : KNOX WARRANTY : If you have a KNOX-enabled device, using CF-Auto-Root will trip the KNOX WARRANTY VOID status ! (but didnt know what it mean XD)

> site didn't looked noob friendly to me so i looked for another one......

- Then I've followed a french link : https://www.androidpit.fr/comment-rooter-samsung-galaxy-s7-et-s7-edge

> So i took files on this page, without using more my brain -_- (didn't seen page is dated 2016... and dunno if the auto root file must be a strict model version...)

- odin said pass ! Samsung pass and secure folder dont work... T-T (i've noted my model version g930fxx4esc5 dunno if it was same before)

> with the message error I got the bad idea to remove oem unlock (perhaps it was bugging the app XD)

- then.... verification problem at boot... reinitialise dont work, useless, wipe...

> So i put my brain finally on, xda, i tried to get back official stock rom version g930fxx4esc5

- from samfirm depreciated thread i've found this site : https://updato.com/firmware-archive...=XEF,BOG,FTM,SFR&v=Oreo(Android+8.0.0)&rpp=15

- update all 4 files in ODIN BL / AP / CP / CSC, phone work but knox is 0x0500 and still no Spass no Secured Folder. Here i am :/

Général questions :

1- These knox problems are only for s7 exynos ?

2- Root and samsung pass never work ? still have someone who say yes O_o

3- Rooted and now unrouted and samsung pass don't work ? still someone who say yes O_o

4- unrooted + full wipe + stock rom and samsung pass don't work ? must i have to try several official rom perhaps ? trying will fail my knox more ? still someone who say an official rom will work O_o

5- Other root method could have work with knox ? but too late if already rooted ?

For me, S7 exynos, R16NW.G930FXXS4ESC5, knox 0x0500 :

6- How did i mistake ? Like i'm not in knox 0x1 but 0x0500 do i have a try ? or if i try i'll have 0x1 and no more try ?

7- Can i have back knox related apps or almost same apps (mainly samsung pass and secure folder) ?

8- Can i go back to initial stock rom ? a real samsung official rom ?

9- Can i try again following from http://autoroot.chainfire.eu/ then this link https://desktop.firmware.mobi/ look for G930F, take the R16NW.G930FXXS4ESC5 version who has the same than my phone ?

10- Must i follow post like : https://xdaforums.com/s7-edge/how-to/samsung-pay-knox-warranty-void-t3549449 or it will be worst hard to get back to normallity ?

11- What is Magisk ? before rooting ? after rooting ? for rooting ? Can i try magisk solution ? or it will be worst hard to get back to normallity

12- On french support samsung-forum just say go in samsung store they got tool to repair with a real official rom for 40€ . i dont believe.

edited : 13- Like that can i still have samsung android updates ?

If no solution to get back samsung pass and secure folder, i'll re try to root phone at least i'll have that, even if knox go to 0x1 it won't be worst ? others problem with app on a rooted phone ? :P
