Just saw a post else where stating to reinstall super su from the play store. It attempted and succeeded in disabling knox. Titanium backup works now! Yay! Does anyone know what would happen if I install a custom recovery from rom manager?
[Galaxy S 4 Q&A, Help & Troubleshooting] lalec:
Not sure how SuperSU would disable Knox (you probably still have it but it doesn't affect any normal usage). ROM Manager is an easy way to install ClockworkMod recovery. I recommend trying more than one because compatibility seems to vary based on version of recovery and version of ROM you have on your phone. I use an older version of PhilzTouch recovery on my S4 because I still use a 4.2.2 ROM.

Anyhelp please

Hi Guys,

I'm basically knox free im on 4.2.2, can anyone give me a brief guide to easiest way of rooting and installing a recovery i.e TW or CWM, hopefully one click solution?

If I then go on to install custom roms i.e omega etc will this then trigger knox? or are they all knox free?, does anyone know the best roms out there are the new s5 roms anygood?

BTW have done a lot of reading but want to be 100% sure and would really like some experienced advice.

Many thanks

I am already at 4.3 with a knox of 0x1. I wish I was still 4.2.2. Jealous of you...

I allowed it to update OTA while I still had the custom recovery and that is when it tripped 0x1.

Anyhow, to clarify my earlier post, after that trip my phone still said it was rooted, but I kept getting the ""An application attempted to access system" message. I searhed that and found the post stating that if I update superSU it will pop a message saying detected knox and would try to disable it. It did give me that message and so far I am able to use the applications that used root and were stopped before.

Does anyone know if a custom recovery will stick, or will I trip another flag by trying?

I see post about losing wifi, which has me leary. Right now I am working fine, I just prefer custom roms with no bloat to what Sammy has dealt me.

Bit OT but Good idea. Make sure u link to xda thread so ppl know.
[Galaxy S 4 Q&A, Help & Troubleshooting] lalec:
The S4 has been known to overwrite custom recovery with stock recovery on occasion. If that happens just install it again. I don't think you will have that problem though since you seen to have made it past that. The Knox flag is already tripped so trying different recoveries won't make that worse. Your flash counter is separate and will continue to increase but that can be reset by Triangle Away if you ever need it. As for updates causing problems with WiFi just make sure you know what you are flashing. GSM radio and LTE radio can be flashed separately and LTE must be compatible with your bootloader version to avoid problems. Some people are reporting great results flashing the NB4 radio along with a GPS patch that greatly increases the speed of signal acquisition. I can find that thread later on my laptop if you need it.

I have no knowledge of the S5 ROMs but the easiest way to root the S4 is to use Chainfire's CF-Auto-Root tool. If you are careful to install a ROM that still uses 4.2.2 bootloader you will avoid Knox.

will it trip if you flash a newer or same firmware with different CSC?
[Galaxy S 4 Q&A, Help & Troubleshooting] tawheed12:
I read all 100+ pages last night.. Just need some minor clarification as there's some conflicting information.

I have a I9500 with 4.4.2.

If I root with saferoot Warranty Bit will remain at 0

When I flash custom recovery it will go to 1. Once this is done, what's the final answer on whether I'll be able to:

1) Flash a stock rom for my CSC using Odin - I've heard some say Odin updates will fail regardless of what version you're trying to install

2) Having that stock rom receive OTA updates - I've heard some say device gets error that it's been "modified" and is unable to get OTA updates

If the above two are possible, what would having the Knox / Warranty Bit flag affect on the phone? Would it get constant error messages about Knox etc?

I bought this phone recently just to try some roms out but now I'm questioning if it's worth it or if I should just sell it and buy an M7. I'm sure there's no warranty left on this phone, but I don't want to trigger the e-fuse and then sell it it someone if they'll have issues with it down the road.

Thanks

Hi Lalec,

Thanks for the reply, I've taken the plunge and used saferoot to root my s4, for some reason it didnt install busybox i dont really know what you need it for and if i can install manually, although SU has installed.

When I know go into download mode there is no sign of knox and it still says everything official although write protection enable?.

My questions are if you can help please:

1. Do I need busybox?

2. Is the write protection enable anything to worry about im sure it was like that before

3. Whats my next step to installing a custom recovery either CWM or TWRP without risking installing knox bootloader, if I install these via odin will it automatically update my bootloader?.

Once I have a custom recovery I will then search for some knox free roms to install via custom recovery.

Many thanks

Just got new g5s from Bell Mobility, it immediately reported ota downloaded, asking me to ok install. Was hoping it didn't already have knox infection. Just booted into download mode and found out bad news that it already has knox:

ODIN MODE

PRODUCT NAME: SM-G900W8

CURRENT BINARY: Samsung Official

SYSTEM STATUS: Official

REACTIVATION LOCK(KK): OFF

KNOX WARRANTY VOID: 0x0

QUALCOMM SECUREBOOT: ENABLE (CSB)

RP SWREV: S1, T1, RA, A1, P1

EDC START

I guess this means there is no reason not to allow the ota to proceed, since the phone already has knox.

Does the secureboot setting mean the bootloader is locked?

Just one more question. Now when I flashed this stock ROM, the bootloader is locked, isn't it ? So now can I flash any ROM which is below 4.4 ??
[Galaxy S 4 Q&A, Help & Troubleshooting] pitastrudl:
You cant lock the bootloader with just flashing the ROM, and no, if you're on 4.4 bootloader, you cant downgrade. Also this debate no longer concerns this thread , so you should ask your questions in the right thread :).

Rooting didn't trip the KNOX flag

I've got an Optus i9507 XXUENB5 4.3 with the KNOX bootloader. It's supposed to be exactly the same as the i9505.

Just rooted the device using the normal CF-Autoroot procedure with Heimdal. When I rebooted into the download mode to finally behold the 0x1, I was surprised by seeing that the KNOX flag is intact. I checked whether SuperSU was working and it was.

Just thought that you guys might be interested.

Sorry for the noob question but

I couldn't find a straight answer:

Will I risk anything(regarding knox) if I install CWM recovery version(i.e. 6.0.4.7) ?

Is it going to prevent me from installing older versions/ older android versions/ triger the knox warranty void to 0x1 ?

[Galaxy S 4 Q&A, Help & Troubleshooting] CarlM34:
If your current firmware is Knox free as you say then you are free to install older versions of the firmware. Installing firmware with knox bootloader will prevent you from downgrading!

You are free to install recoveries without tripping anything

I know that.... but you didn't answer my question....

Is there any relation between the recovery to the knox?
[Galaxy S 4 Q&A, Help & Troubleshooting] CarlM34:
Recoveries do not include Knox....the boot loader does......so no..........The only relationship is the custom recovery will trip knox flag if you have a knox boot loader.

Statement about Knox discussion

I personally think that all statements of even senior forum members all around the net should be corrected to something like this:

AT THE MOMENT noone has yet figured out how to remove/downgrade the knox bootloader.

Never say never, never say somethings impossible! Some day there will be a cool guy who'll find an exploit in this knox security architecture, I'm pretty sure on that, you'll see. If it's possible to get the knox bootloader with just one OTA update package, so there will also be a way to revert this. I'm sure of that.

After all Samsung did't engage some voodoo priests or wizards to work this knox out, or who's thinking that?!

So, Hackerz and Crackerz - just WORK HARDER!!!

Hi everyone,

If you are on a rooted 4.3 official ROM, you can get the latest official ROM rooted without tripping the knox flag to 0x1. You just have to update with Mobile Odin Pro and check "Enable EverRoot", "Inject SuperSU" and "Inject Mobile Odin".

You can also use Wanam xposed to get the status back to "official". ;)

It's what I've done, my ROM is 4.4.2 with knox flag 0x0 and statu "official", despite of this, I can't use Knox app. It's not very important for me because I don't use it but I'd like to know why. :confused:

Downgrading

I've just ordered an S4 after months of waiting for the price to drop - then I stumbled across the knox issue.

I have read around but cannot answer these questions:

1/ If you trip the knox flag by rooting etc but never plan to use knox does it matter (warranty aside)?

2/ Does tripping the knox flag prevent you from doing anything else in the future other than using knox (for example like downgrading to an earlier stock firmware using mobile odin once rooted)?

I just about have enough time to cancel the order if it means I can't have the freedom to flash away like I have been on my S2.
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
Hi,

1. No

2. The knox bootloader only prevents you from downgrading to an earlier firmware than is currently on your phone.

:)
[Galaxy S 4 Q&A, Help & Troubleshooting] dimbo33:
I have read that if you are running a knox firmware and attempt to downgrade then you cannot upgrade again to a knox firmware even using odin. This seems horribly restrictive and I have attempted to cancel the S4 order (I may be too late - we'll see). I suppose that it may be possible to get around this by using a custom ROM, but I don't like this restriction. If my cancellation is successful I can see me going down the Nexus 5 route.

Edit: I am too late to cancel the order. My fault for not researching thoroughly enough. I've been looking forward to buying an S4 for months - I feel like a complete clown. No one to blame but myself!

This raises some more questions:

1/ If you go down the custom ROM route, are there any restrictions here in flashing whatever you like? Can you upgrade/downgrade to other custom ROMs even if the knox flag is tripped?

2/ If you root the latest 4.4.2 firmware using cf auto root, how do you ever upgrade it from there if OTAs are no longer possible?
[Galaxy S 4 Q&A, Help & Troubleshooting] Lennyz1988:
You are mistaken.

You cannot downgrade to some older versions (depends on the bootloader). But you can always upgrade back.

Yes you can take any custom rom and swap freely between the roms.

Upgrading stock roms goes with Odin/Heimdall. That's always possible even with Knox tripped.
[Galaxy S 4 Q&A, Help & Troubleshooting] dimbo33:
I am curious to see what firmware the unit will be running when it arrives. If I am lucky it will be one of the pre knox firmwares, in which case I will root and then install a custom ROM. This way my understanding is that I will not have a knox issue at all. The easiest way to install CWM is with S4 flasher from the play store once rooted.

More likely though the unit will come already running a knox firmware. Here is where my understanding is shaky so please correct me if I have misunderstood.

If already running a knox fw, I might as well upgrade to stock 4.4.2 OTA as there seems to be nothing to lose. I can then cf auto root (tripping the knox flag in the process) and then install CWM using S4 flasher. Thereafter I can install CM11.

If I wish to go back to stock 4.4.2 I'm guessing I can do this by either restoring a stock nandroid or by re-flashing stock using mobile odin yes? There will be no downgrading of stock, just a return to the pre CM11 version.

If there is a subsequent stock update I'm guessing that OTA will not be possible (due to the tripped knox flag), so can this be applied by using mobile odin?
[Galaxy S 4 Q&A, Help & Troubleshooting] Lennyz1988:
You can flash any update true Odin and almost any version with Mobile Odin. The only firmware updates you can't flash with Mobile Odin is if it contains a bootloader update.

So to summarize:

- You can flash any custom rom.

- You can flash any new firmware that comes out.

- You can always return to stock.

If you don't have the latest firmware when your phone arrives, then I would skip updating but root it right away. There is no point in updating it if you want to flash CM11.
[Galaxy S 4 Q&A, Help & Troubleshooting] dimbo33:
I've just received the S4 and it's running 4.2.2 - XXUAMDM - which I think is pre knox yes?

If so, I'm guessing that I can root and install CM11 without facing the knox issue if I come back to 4.2.2 yes?
[Galaxy S 4 Q&A, Help & Troubleshooting] malybru:
Hi,

Yes,you are lucky enough to have a pre-knox bootloader.

Install a custom recovery and install only custom ROMS through it , and you will stay knox-free.

Always read the first post carefully and make sure the ROM does not need or contain the knox bootloader to work.

:)
[Galaxy S 4 Q&A, Help & Troubleshooting] dimbo33:
My understanding is that CM11 neither contains nor needs the knox bootloader. Please correct me if I'm wrong.

Kingo root or root de la vega?

Try the easiest rooting method called kingo root, its easy and free, it's worry free, but may not be successful, I never tried it before because t-mobile rooted mine, and also tripped my knox with phiz touch recovery and the lidroid rom, just find it, download it, install it, open it, plug your note 3 in, enable development mode and wait. Doing this may not: change your recovery, damage system, or brick your device, but will give it the ability to do it, there is no guarantee that it can prevent voiding knox. Or try "Root de la Vega." If I were you, I would not consider worrying about the knox, the best rom is lidroid, if you want download this rom, find the sm-9005 copy, it works with all version, but they make roms for samsung phones only.
