so, ive had two s4 i9295 for almost a year now and tried diffrent combinations with it. stock, upgrades, custom roms (the few that are available).
i decided to start the thread to get all the questions answered in one place, it can be usefull for others trying the same thing.
after trying all sorts of roms, i got back to stock 4.2.2. (ML3), rooted with cf autoroot and removed bloatware with titanium backup
what i like about the stock rom is: camera (hdr, drama, eraser, panorama, etc), nfc, phone audio, calendar widget, reliability, etc. things i didnt find in any other custom rom to be either working properly or have the same amount of options. what i didnt like was having to use a third party browser to display flash content.
i tried the 4.4.2. both NE1 and NH2. after NE5 you cant downgrade, apparently. i didnt realy like the 4.4.2 then, it heated more, ate up the battery faster, etc.
i like to keep things simple and clean, so here are my questions:
1. is there a way to revert back to 4.2.2. after upgrading to NI1, for example?
2. whats the best way to root NI1, without triggering knox?
3. how to remove knox in both 4.2 and 4.4?
4. how to use native browser to display flash in 4.2 or 4.4?
5. which are all bloatware safe to remove without losing NFC and other functions specific to the S4?
thanks
When you have NH2 in Download Mode,
it is of interest to know the status of lines and most interesting of KNOX.
This is what
CWM 6.0.5.0, CM11, NE4
say:
ODIN MODE
PRODUCT NAME: GT-I9295
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX KERNEL LOCK: 0x0
CSB-CONFIG-LSB: 0x30
BOOTLOADER AP SWREV: 1
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
What is written in upper left corner of your screen?
the phone that i have now only had NE1, and i was able to downgrade to ML3, which i had until today, when i gave custom roms a last shot with PAC rc2 4.4.4.
it now says:
ODIN MODE
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
and thats it, no other lines about bootloader, knox, etc.
i dont have the one on which i tried NH2 anymore, so sorry, cant tell you. the story with that one is here http://forum.xda-developers.com/showpost.php?p=55287647&postcount=23
the thing i mainly want to know is if i try the latest NI1, can i revert back to ML3, which is the best for me so far.
Suspect some differences between bootloader NE4/NE5 and newer ones, like NH2 or NI1.
Check here to identify bootloader and important LTE modem (NON-HLOS.BIN) relationship: http://forum.xda-developers.com/showthread.php?p=56049236
This is of course open for discussion because it is my understanding of a collection of xda-forum postings (with links). One of these is from Chainfire (provider of root) spending hundreds of hours looking into Knox.
http://forum.xda-developers.com/showthread.php?p=45666586
KNOX 0x1 cannot be reversed once tripped. Once updated to Knox enabled bootloader you can't go back. Going back can trip Knox 0x1. Removing all Knox apps from ROM do no difference if Knox is tripped 0x1.
Unless responsible developer has altered something, the bootloader and modem stay untouched when flashing CM or AOSP based ROM on S4 family device.
yes, i have read about the bootloader being changed, thats why i thought its better to ask first and then update.
and most threads about rooting and the bootloader arent up to date. as far as i know, the only way to root after NH2 is with custom recovery and superSU through odin. at least that was the only way when i tried back then. chainfire and towelroot didnt work with NH2. and modifiying recovery after NH2 triggers knox. that secured bootloader didnt allow me to downgrade even to the ML3 on my other phone, because it had an unlocked bootloader, same as NE1. similar reasons here, i think http://forum.xda-developers.com/showthread.php?t=2447832. please correct me if im wrong, and if there are other tested ways to root.
but anyway, i dont care about knox, as i bought the phone second hand and dont have warranty. i care about not being able to downgrade if i dont like the stock 4.4.2. is that possible?
Hi all!!
After spending a huge amount of hours, searching the forum, I still have doubts...
Is it possible to downgrade from Lollipop, to kitkat, without tripping knox (warranty void) in the S5???
Some say, that flashing with Odin it's ok, others say that will go in a loopboot, others say that the bootloader is not compatible, and flashing a new rom will trip knox, others say that if the rom is official, will not trip knox...
What to believe??????
If there is a way to downgrade, safely and without tripping knox, please show me how, in a step-by-step process, I really appreciate it.
Here are the mobile phone data:
SM-G900F
Firmware: G900FXXU1BOD3
Thanks in advance!
Downgrade away, I have the G900F, and flashing KK over LP works fine and does not trip KNOX
You only trip KNOX by flashing custom stuff, stock ROMs are signed by Samsung so do not trip KNOX
The only issue I had was having to flash KK twice, first flash worked but wouldn't boot, flashed again, booted first time

Hi Detection!
Thank you for your enlightement, but tell me, you flashed your device using Odin, right?
Thanks!
Yep, ODIN 3.10.6

And how did it go?? Did You safely downgraded to KK?? I was thinking about it, got my S5 with pre-installed Lollipop but without root I can't block adds and stuff - it's rather annoying.

You can root lollipop, but it'll trip KNOX
CF Auto Root
Yeah i know that CF-AutoRoot works on lolly but I'd rather keep my warranty void Guess no new method on gaining root w/o tripping knox was introduced to S5 design If i recall S6 is rootable now without knox messed up but no go for S5
I flashed my S5 a few months ago from 5.0 back to 4.4.2, and last week the same thing, but on my gf's Note3.
It's kind of easy and safe to do, if you do some research in advance:
- find exactly which ROM you need (the wrong one won't work and make ur phone temporarily unusable).
- download the official stock ROM
- KNOX won't trip if it's an official stock ROM.
- Boot the phone in recovery mode to wipe the cache partition and do a factory reset (after backing up the important data).
- Flash with Odin. There's many youtube tutorials on that one.
Enjoy.
If you didn't do a factory reset, wipe cache partitions etc you'll almost certainly get stuck in bootloop after flashing. In that boot up in recovery mode again, do those wipes and then restart.

Hi all!
Tell me something, after flashing KK, software update is allways trying to update to LP... is there a way of avoiding this, without root access?
Thanks in advance!
you need to disable the FOTA processes, but I'm not sure you can do that without root
Ok guys so let me get this straight - I only need proper KK image, provided by Samsung (their signature and so on) with my CSC (in my case Polish XEO)? Then connect my phone with PC, start ODIN (any particular version?) and what to choose, what check and what not? Sorry for this only had HTC before (and Sony and LG but those are wifes phones) and flashing on it was a bliss, especially when You had S-OFF.

Not stop, but you can delay it indefinitely by clearing the cache in recovery each time it has the update ready for you to install
Then boot back into droid, and hit the install button, which will fail because you just deleted the update in recovery
Rinse and repeat
You can root KK without tripping KNOX though, so no reason to not root it really

Hi Detection!
I know we can root without tripping knox, but I am afraid of doing something wrong...
Can you tell me how to do it, in a safe way???
Thanks in advance!

Either make sure your KK ROM is a pre June 2014 build, if not, either flash with ODIN, or read up on how to downgrade only the Kernel to a pre June 2014 KK kernel, then use towelroot app to root it, and flash your original Kernel back
All the info you need is here on XDA, might take a bit of reading, but you should really learn as much as you can before blindly flashing things anyway
I read in another thread, someone said that if your S5 came with LP out of the box, you can't downgrade to even official samsung KK without tripping knox. I'm not sure how true is this or whether that person is just blowing smoke.
Well actually it seems fairly straighfoward to go back to stock, if you have the appropriate stock image to flash with Odin. I'm just used to do the whole "unlock bootloader, flash recovery, flash autoroot/rom/whatever" process on other devices and it feels weird to just load up Odin and do everyhing. So that's an insecurity.
I'm more interested in knowing whether Samsung "knows" that you rooted/unlocked the device, for warranty reasons. If sometime I decide to go back to full stock and at some point I need to return/send the device for some service, I want to know if they can tell whether the device had been previously rooted. On my motorola xt1092 unlocking the bootloader requires some sort of code from Moto itself, so even if you go back totally stock you can't get rid of the "unlocked bootloader" msg, let alone that they have you already registered on their system as having non-valid warranty.
YES. Atm there is no root method that won't trip knox and if knox is 0x1 samsung will always know. Some providers don't care about that and will fix ur phone/tablet. Especially if it don't even boot or some mechanic problem, just flash stock firmware with odin. My personally was very insecure when flashed firmware 5.1.1 then kernel and then root with odin (always used TWRP on S4) but all worked ok, just read the guide, real all post and all will be ok. If u wan't then go go stock just flash the same stock firmware and you will have it stock with no root stock recovery but knox will be 0x1

Thanks for the info! I found out there was a piece of software called "Triangle Away" which helped reset counter to 0x0 when going back to full stock, but i can't find out if it would work on the Tab S2... http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114

It was flash counter not knox. Knox is literally impossible to reset. Triangle Away only works on older devices. List can be found here: http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114

Just to reconfirm that, since I was also a little concerned about that (I have a T810 btw, not a T815): While the stock firmware on my device works 'well enough', there are certain things i'd rather it was able to do. Knox however has me holding off (at least until the warranty expires). Does the same apply to the T810? (There is no root method that won't trip knox.)
ATM no. The only way to root Tab s2 is to trip Knox. King root will root your device with no Knox tripping but it will last until you reboot
Been out of the flashing game for a while (last device was an S4)
I'm wanting to start modding my Galaxy S8, but before I do I'm wanting to do a full firmware backup to restore to if things go wrong, or if I sell the device on.
Ideally I'd like to be able to restore to the point where the next user wouldn't recognise its been flashed other than the tripped knox flag (ie original recovery, modem, bootloader, the lot)
Also.. Samsung Pay. I've read about fake knox flag, does this enable Samsung Pay? Do I need to be rooted to do this? Can I flash from my backup (ie to original) and get Samsung Pay back?
Can anyone point me in the direction of a rock solid guide for this?

If you have an s8, you are in the wrong thread.
You can download stock filmware files from Sammobile or Updato, which can then be flashed with Odin.
Samsung Pay will never, ever work after tripping Knox.
Flashing stock filmware is not enough, it will take a motherboard replacement due to the Efuse, google pay should work though with Magisk or relocking to bootloader.
G'day XDA Developers.
I would love to root my Samsung Galaxy S10 then install a custom recovery (TWRP) then flash a custom rom (LinageOS) how ever I trip Knox when ever I attempt to do these things. So I was wondering how do you go about disabling Knox?
After some Googeling I found this site https://www.progeeksblog.com/how-to-disable-samsung-knox/ How ever these methods require you to first root your phone but rooting triggers Knox.
So I am at a loss here I am running stock android rom until I figure out how to bypass Knox.

thats always been around lolol.. but regardless ur post was more about not tripping knox which ur knox is in fact tripped so "disabling" knox doesnt change anything really.. also, that zip doesnt really disable knox.. it disables verification, defex, force encryption etc.
Actually it says that it disables vault keeper which is supposed to replace Knox but any way yea your right my post was more about flashing anything trips knox so how are you supposed to get around that.

vaultkeeper is not to replace knox.. samsung bases all their security on knox.. vaultkeeper is in addition to knox..
there is no way around tripping knox.. the knox warranty bit is a physical fuse that gets blown when bl is unlocked and u flash a custom firmware and there is no way to reset it..
magiskhide can sometimes "fake" it but with safetynet improving if ur device is set to use hardware then there wont be any way around that either in the long run

I don't care about voiding warranty. What happens when I try and flash anything custom on the device Knox gets tripped and the phone refuses to boot. Thats what I am talking about trying to bypass.
I have Galaxy Tab Active3, which is locked to organization and it seems to have Knox enabled.
I want to Factory reset it so I can use it for private use.
I cannot get it into download mode, but I can get it in recovery mode. However, the Wipe data/factory reset option seems to be disabled.
Dialing *#0*# and *#*#88#*# from emergency dialer do not work either.
Any advice how to remove the Knox protection and factory reset the device, so I can set it up from scratch and remove the organization lock?
