So i messed up my tab and lost my backup so i used a Firmware from hong kong or something and then i lost knox and its nowwhere to be seen and i cant get root because of it and also my tab wont charge through computer. HELP!
My tab s never charges from comupter/ well its really slow. How did you lose Knox? Try flashing the firmware from your country and then use cf auto root. I don't have Knox because my ROM I have is debloated which to me Knox uses a lot of battery. Hope this helps!

I'm currently using stock MF6 firmware and there is no indication of the Knox warranty void flag in download mode. Does anyone know which firmware introduced this flag on the S4 mini or is it not implemented, yet? I'm asking because I want root access and need to know which prerooted firmwares I can choose from without this flag.

As far as I can tell, there's no Knox flag known on any S4 mini firmware or variant. Definitely mine has no sign of it either. And from what I read, at least ith the S4 it was never transparent, only when the flag appared could you kill it, in older firmwares no matter what you did the flag was never set until you upgraded and there was something considered wrong then.
4.4 is supposed to bring Knox for the mini so it may bring the flag, which could be easier, harder or the same to avoid as the S4, only time will tell I guess. If it's similar, hopefully enough will have been learnt by the time S4 mini get 4.4 that we can easily get around it.

Thank you for your reply. Which firmware version are you using?
(I9195XXUA)MG3 (which is 4.2.2 / JDQ39). It's currently the latest for my CSC. I may root soon perhaps using a prerooted firmware (since mine is so old) but I'm waiting to see if anyone has tried it on a 16GB version. I didn't mention before but I guess it's clear now I have an I9195 but I haven't seen any mention of Knox flag seen for any variant of the S4 mini on current firmwares.
My s4 mini (I9195) came with firmware MF7 and was upgraded OTA to MG8.
After that I flashed with Odin to MH2 (Android 4.2.2).
Thereafter I flashed a custom rom (Slim with 4.3.1).
Where and how can I see whether my Knox warranty void might be 0x1 now.
And what if I flash back with Odin to firmware MF7?
Is that still possible without a later upgrade problem?
Curious about your info.
New Rom XXUBMJ7 whit KNOX bootloader (aboot.mbn) and aplications.
After flash this Rom we have on Download Mode:
KnoxKernelLock: 0x0
KnoxWarrantyVoid: 0x0
Like on Note 3 N9005, if we flash something, customer, root, KnoxWarrantyVoid: go to 0x1 and this is not reversible.
To Root
The Root-Kit-V1 install all superuser, SU and busybox but after reboot the SuperSU can't access to system, KNOX not permit.
To solve this we must flash after, on recovery the UPDATE-SuperSU-v1.65.zip from Chainfire. After we have root alright.
My case like on Note 3:
I not need the KNOX, the phone is only for me, then after root I delete all KNOX apk + odex from system/app.
Good luck
Is it possible to go back to old bootloader WITHOUT knox?

Many info about KNOX.
Hello folks,the time has come for me to replace my Nexus 7(2012) and i'm thinking of getting a 8.4 inch Tab S.
.Since i'm used to Nexus' unlockable bootloader,and not having a Samsung device since Galaxy II,i'd like some info regarding rooting and generally tampering with this device
.Do you lose your warranty if you root this?Or is there any trick like "triangle away" was back in the S2 days..?
Furthermore,do you think this device is a good choice?In my country i find the 16GB variant around 280 Euros,and i can't seem to find anything remotely good for that price..
Lastly,how does the device perform with custom roms?I really hate Touchwiz UI.. :S
Thanks in advance for the help
The bootloader is unlocked on my Tab S 8.4 WiFi only model, not sure about the LTE version if you get it through a carrier like AT&T or Verizon.
As far as rooting goes, super easy with CF Auto Root. Thank You Chainfire. And yes, you will lose your warranty as rooting will trip the knox flag and there's no way of undoing it with Triangle away or any other method.
I haven't tried any custom ROMS yet, but I'm happy with the performance after I debloated it and I'm using Nova Launcher instead of Touchwiz.
Also just to let you know, most of the system files are Odex. Not sure if that matters to you.
That was all i needed to know,thanks for the reply !!
Is there anyway to root the Sprint Samsung Galaxy Note 4(SM-N910P) with out Tripping KNOX? I have tried towel root and it is not supported. Any help would be appreciated
Chain fire auto root then install twrp through the ROM I think. I just flashed through Odin though
I believe there is no way not to trip the knox if you root. It is a permanent change. However sprint will honor the warranty as long as you flash back to stock.
Damn, one can only hope. And when I had my s4 and I tripped knox. I had a SIM card issue, and they said sense it was tripped there is nothing I can do.. sorry about your luck
I had my s4 and it lost all audio in the headphone port somehow and I was running slimrom at the time. He wanted to see my phone and he asked if he could install root checker, of course I said yes. But said one sec let me check something, went into the settings and disabled root that way. He did his thing and then fixed my phone. When I turned in my phone, I am on the easy pay thing, it was still rooted and Knox was tripped. After I had my new phone and was ready to walk out. I asked him about it. He said he didn't care cause it gets shipped out and they wipe the phones and reinstall the factory image.
I guess it just depends on the tech that's helping you.
My screen had a bit of dust under the screen, I was rooted Knox tripped and had the screen replaced no questions asked. Like stated above just depends on the tech.
Shouldn't have posted this here and needs to be moved.
Does the sprint exchange work if you didn't buy it at store ..? Bought mine at bestbuy
Hi everybody!
I have a Samsung Galaxy Tab S 8.4 that I have rooted with TWRP and SuperSU.
And now I want to sell this tablet and I want to unroot it so that the buyer could use the warranty of the device if needed.
How do I go about doing that? If I unroot it, can the repairmen see if KNOX has been broken?
Sorry for bad terminology, don't know much about rooting.
Not possible to reverse knox. The warranty us void.
Ok, thanks!
How do I go about making the tablet as stock as possible then?
I've installed TWRP and SuperSu.
The best way to get as stock as possible is to flash a stock firmware via Odin! Just download the stockrom matching your device at sammobile.com/firmwares and flash via Odin
I read on this forum that most of the time they will repair your tab even if the knox has been tripped.
The latest KingRoot now has an uninstall feature if you need to return your tab.

It will still say custom. The only way is to flash stock firmware.
hello everyone,
I have and use android phones last 10+ years, always rooted. But I never had samsung phone.
Now I hear only half informations from my buddy, that its dangeous to root samsung because of knox (i dunno what knox even is).
So, now I'm thinking to buy S20 and want to root it, and my question is..:
If I root it, is anything ''broken'' on the phone ? Can phone still recieve official Samsung OTA updates?
What are minuses? what to look for? What about this "knox"?
Please need informaions
Well, I've owned a couple of Samsung devices over the years and I guess I can speak a bit from experience. Here's what you should know:
1.- U.S. phones have their bootloaders locked, so avoid buying a U.S. variant if you want to root it (some people want them for their Snapdragon chips)
2.- Knox is an e-fuse in the phone motherboard. Once you trip it by flashing custom software (root it), then that fuse will be tripped forever. You cannot get your Knox your status back to official unless you change the motherboard. Even flashing stock firmware will never get you this back to official.
3.- A lot of Samsung's security apps check for this fuse and will refuse to work if they detect that you've tripped it. Samsung Pay, Pass, Secure Folder are just some examples of features that will stop working when they detect a tripped Knox fuse. Some of these have bypass with root, but some don't.
4.- You will not get OTA updates with an unlocked bootloader, let alone root. It IS possible to get them back but only after flashing stock firmware and blocking the bootloader. These don't seem to check for Knox.
Understood, Thank You alot for informations and help!

Hiiii. I currently have a Samsung S20 and I have rooted it before. Once you root it Knox security will be tripped and you will not be able to get it back. This means you will lose access to apps like Samsung Pay, Samsung Pass and Samsung Health. You will not receive OTA updates if you're rooted, but if you flash stock firmware again and lock the bootloader you can start receiving updates again. I currently have a custom ROM installed and I have my ROM rooted. To me, it's been a great experience overall. I didn't really use the Knox features, so I didn't care much about losing it. I have loved rooting my S20 and using a custom ROM !!

Actually you can use Samsung Health, just currently no version above 6.19 (2 versions behind current) until we find a way to patch it...i use it daily with my Watch 4 on Rooted S20+ 5G....

Yeah you can flash updates with something like Odin (never used Kies myself, I don't know if it still works)
