Return to Stock & KNOX - Galaxy S6 Q&A, Help & Troubleshooting

I've currently rooted my Galaxy S6 and I'd like to return it fully to factory stock without tripping KNOX. Unfortunately I'm going to return this device since the memory management issues are a dealbreaker for me on a $800 phone.
Will flashing stock firmware trip KNOX?

It shouldn't if you use Odin and flash the correct FW package

Doubt wherever you are returng it to will even look at that unless u actually bought it from samsung themselves. U should be good as long as its back to pure stock software

Knox Trip Questions

Alright I had the Galaxy S1 S3 and S4. I jumped ship to the Moto X before the 4.3 update which brought Knox tripping to the mix. Im now rejoining the party with the S5. I have read extensively on it but I still have one question. If you use CF root method you trip knox and void warranty.. I know there is not a knox re setter, But can you at least flash stock with odin and take OTA'S?
It's hard to tell because Samsung hasn't release an OTA on the s5 yet. But in theory the tar file flashed through odin puts everything back to factory, except the knox trip.

Yes because I did a million times on my S4.

[Q] I have Mobile Odin & Firmware Flashing Questions

Nothing too crazy.
1. Will flashing a stock Samsung firmware using Mobile Odin trip my Knox warranty counter?
2. Will downgrading to an older stock firmware/kernel brick my device due to Knox and its bootloader? I have been getting conflicting information on this topic from the forums.
Anybody? No? Ok..
Yes will trip. /possibility

To Root or Not to Root

Hello Community!!
I have owned many androids over the years, and have recently got an S6, hoping to dive back into the game of rooting, modding and messing around until my phones works the way i want it to. There are MANY things that really Piss me off about my T-MObile variant of the S6, including the horrible battery life, bloatware, and lack of personality. I Really would love to root my device, but KNOX. OMG what is this?! If i Root, no Samsung pay? What other downsides are there to rooting? But recently, my phone installed "ANdroid Pay" SO I am thinking, I should just root, forget Samsung pay and just use Google pay or whatever they call it.
As you guys can tell from my sig, I have been very inactive on these forums. I am hoping someone can give me some advice here---
Thanks So much

There are pros and cons to root.
The first pro is limitless customizations and personalizations.
The first con is OTA updates get disabled.
Another pro is you are able to dramatically improve battery and overall performance using various apps.
Another con is your warranty will be void, assuming you tripped KNOX.
If you trip KNOX, Samsung Pay no longer works; if you have root (even without touching KNOX) Android Pay does not work.
I obtained root just to prove to myself it could be done.
Since then there have been dramatic improvements with speed and battery life.
Package Disabler Pro can freeze a lot of the bloatware without root: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en
Hi,
It's a highly personal decision. I myself for the first time am holding on rooting - I was the one who made the most famous Xoom rooting tool and also S4 Linux Root Script, so that tells a lot. The thing is, meanwhile my device is satisfying my needs, and I'm really curious about Samsung Pay, as it has a way wider support than Android Pay and other systems.
The best thing about rooting in my opinion was the endless system customization - specially after Xposed was released. The way better data management I had, better system control and some exclusive apps that require root or works better with root. If you are really pissed about Samsung TouchWiz apps and system "features", rooting would be a nice idea. Just keep in mind that after rooting Knox will be tripped and there's no turning back with Knox. Depending on your country, Knox trip also means warranty void, because once rooted you can unroot and make it looks like nothing happened.
Just adding what was already said, but Android Pay doesn't work with root.
All the best,
~Lord

Rooting doesn't allways mean tripped knox. I have my G920F rooted and knox intact. This can be done even after updrade to 5.1.1 stok firmware.
An android phone for me is worthless without root permissions. I need it for:
adaway adds
iptables (firewall)
better battery life (debloat)
titanium backup

I was only aware of root that can be applied before upgrade to 5.1.1.
Can you advise how you applied root after 5.1.1? Thanks.

Just install de 5.0.2 engineering bootloader via ODIN. Then instal TRWP via ODIN.
After this two steps you can flash whatever you want via TRWP.
Edit: with the 5.0.2 bootloader you will loose fingerprint scanner, the rest works great, at least with the custom rom I am using.

Keep in mind this engineering bootloader does not work with all variants. For example there is no Eng Bootloader for the Canadian phones.
Thank you both. I have the international SM-G920F (technically it's the dual Sim version, SM-G920FD, (from United Arab Emirates)).
So, to confirm, would the eng boot loader still work on my device variant, and allow root without tripping KNOX?

I have the single sim version of the G920F, so I don't know if it will work with the dual sim.
I don't think that it will strip you knox...
... and I think that if your phone doesn't work with this bootloader, you can just flash the correct one and make it work again.
But these are just guesses... you decide if you want to take the risk.
Good luck.

Thanks. I did some additional research, thanks to your advice about eng boot loader, and seems like it will work ☺

Hi,
I wouldn't risk that "you can just flash the correct one and make it work again". If you know how a bootloader work, if it gets broken there is no way to get to Download Mode and flash a new firmware/bootloader.
For information sake, a bootloader is a piece of software that is the first thing loaded when you boot your device, it comes before anything, be it kernel, be it recovery or anything else, that means, if you have a broken bootloader, the moment you try to boot your device up, it will try loading BL and it will fail, so it will shut down back again. I've had a broken BL once before on S4, the only way to recover was a direct flash of software in system chip using a tool called JTAG.
So, all I can say to users who still didn't get it: beware with this. It seems that many people are getting successful results, but it's an extremely risk procedure, make sure you read every single instruction and follow it, the possibility of a hard brick is high.
Even still, it's a great find, thanks for sharing with me, I didn't know of this until early today .
All the best,

I wonder whether Samsung pay will work again after reflash stock rom after root? Is it like knox, once rooted you will never have it no mater what you do including going back to pure stock?

Did you mean, once rooted we can unroot and install the stock firmware and hence tripped Knox will be restored as well?
Or the unrooting will only help to restore the stock but the knox will continue to remain tripped. I would like to know this as I am considering purchasing S6. The last samsung phone I owned was S2 and used that for 3 full years with out any problems.
Thanks.

Once Knox is tripped its tripped but, yes you can flash original firmware and as long as you factory reset it, it will be unrooted and ready for official updates.

Thanks. But can you be a bit more specific of if the unrooting, flashing stock, and factory resting will finally untrip the tripped Knox as well? My question in the event I need to take this back to a service center to claim warranty for whatever reason, is there any way for them to know that I have voided warranty if I unroot, flash back the stock and factory reset?

Once tripped there is no going back. Voided warranty depends on laws of your country and your retailers policy.

YOU CAN NOT UNTRIP KNOX, you can reflash your firmware from Sammobile, http://www.sammobile.com/firmwares/database/SM-G920F/
use odin and then after you flash, go into recovery or use system settings and conduct a factory reset. It will say Official in the status but, since they will reflash your rom anyways, they will see the knox trip.
It depends on where you purschased your device whether or not they will warranty it with Knox tripped.
Honestly, anyone who roots should understand this information before hand. You should always know how to return to stock unroot.

After rooting my 5.1.1 without tripping Knox, with the 5.0.2 engineering bootloader (as as described a few posts ago) I have flashed a stok rom with odin and then everything went back as it was before the rooting procedure.
1. I was on stok oficial rom with oficial bootloader.
2. I lost root.
3. Knox was still intact: 0.
4. Fingerprint scanner and MyKnox worked again.
So: after upgrade to 5.1.1, rooting with the 5.0.2 engineering bootloader seems to be safe and also easy to bo back to stock... at least for my model (G920F)

installing custom rom help noob

hi guys, since samsung s2 i dont use samsung mobile phones so its a long time
i bought a galaxy s6 and the original room is full of aplications i dont use, the ram avaible is a joke and the battery life isnt very good
i want to install a custom rom
im with the last ofical 5.1.1., if i install a custom rom i will loose right to waranty? there isnt any way of revert the root and count?
thanks
You can unroot the device and reflash the stock ROM, but you cannot revert the Knox counter. Whether or not you loose your warranty depends upon the laws in your country.
so its impossible for now to root, flash custom recovery and flash custom rom without activate the know counter?
Search for the engineering 5.0.2 bootloader. Unfortunately if you are on 5.1.1 already, then it is of no help.

Flashing Stock Android ROM from another country

I purchased my SM-A520F from UAE. I am currently using the phone in India.
All Samsung Mobiles sold in UAE have VOLTE disabled by default, and hence my phone do not have it. However, majority of the 4G carriers in India use VOLTE and this causes problems that are not minor.
Rooting the phone will probably void warranty. I was told that I can flash stock firmware for this device released for India without having to root.
1. Will this void warranty? I contacted customer support of Samsung UAE and they told me it would. But I dont believe them since sources on the internet say otherwise and I won't be rooting the phone.
2. If I were to go ahead with this, where can I get the official firmware? Is there any option to download this from Samsung website?
3. What is knox counter? Will I be able to do this without "tripping" knox?
4. Once I download and install stock firmware from a different country from a website like Sammobile.com can I still receive OTA updates?
5. After flashing a firmware downloaded from a third party website, how safely can I use applications that use sensitive data like S Pay and mobile banking applications?
Thanks a ton in advance.

1. If knox trips, warranty is lost
2. Try to Google... you can use sites like galaxyrom or Sammobile
3. Knox is a protection thingy made by samsung.... it controls and looks in all of your system... this isn't bad and keeps the phone stable by protecting the kernel... the knox counter can be found when entered odin/download mode... here you can see something like: knox warranty void 0x0 or 0x1... 0x0 means it hasnt/didn't trip yet, 0x1 means you're pretty much F'ed
4. I don't think you can receive ota updates when you have a rooted system and a custom recovery... and I don't know if u can download it from another country... sorry
5. It's safe... if it is official firmware then there are no worries ?
Hope this helps... ?
