    hey. im receiving a replacement s3 from Virgin because my current s3 has a slight case of "pixel burn" on it. well my current s3 is old so it came with android 4.1.2 and this allowed me when the time came to avoid knox and all it hell and install a know free version of 4.3. well on my new s3 im positive that ill be getting a knoxed up phone (lol see what i did there:) ) well like thousands of others i dont want knox. so ive looked high and low for any headway on the subject of removing it and found mixed results between note 2, s3, note 3, and s4 forums.

    my proposal is to anyone who already has knox and has tripped the counter, can you succesfully downgrade to a partially working version of android (at least so it boots) and then somehow flash a bootloader to match the older version, thus getting rid of knox. the android and loader idt have to be specific to VM just to each other to they boot (without a brick because i know changing bottloaders is some serious cheese).
    turn the VM phone into a Sprint version or a T-Mobile version of 4.1.2 just to get knox out. then restore to all the VM specific software and fix anything that maybe broken (like wifi, mms, 4G, etc.) after a update to a knox free 4.3 such as Dankx's Midnight ROM or even CM.

    its a thought i had floating around but im not sure if its even feasible.
    its a bold move and since my current phone is already knox free it would kind of be a waste (and im a wimp cuz i need it for the next week and a half while i wait for my replacement)

    can someone test this idea and tweak it so its possible. or at least tell me why this would probably never happen

    no a knox bootloader downgrade of anykind would brick the phone. even a tripped knox flag. it is the fact your changing bootloaders that would brick.

    Your replacement phone doesn't have to come with Knox, its unknown unless you've received the device already and know, I bought my s3 around Christmas and I'd came with 4.1.2, I accepted the upgrade tho so I have Knox but its yet to stop me from doing anything

    As struckn usually says which is true, companies like VM or sprint keep these devices most likely in a warehouse, in which they most likely try to get the oldest ones out first so there's a chance youll get a 4.1.2 Knox free, in which case reject any ota pop ups and if you connect the ur PC don't allow kies to push it either

    In the scenario that it does come with Knox, thus far the only absolute No-No (that I'm for sure on at least lol) is to try to flash absolutely anything that has an included bootloader
    But with that being said almost anything in these forums could be flashed as they have no bootloader and they have the sprint asserts removed, but as a safety precaution just remember to read,read,read, and read some more lol since our device has something like Knox most devs or thread authors on ports or whatnot usually say what it has, what it doesn't, and if u can flash with Knox or not

    well unfortunately it came with knox. but the day i got it i rooted and romoved as much knox crap as i could. flash a few extras like "more toggles" and SuperSU with the help of PhilZ recovery. so i guess so far its all good but i hate that im limited to what i can do in comparison to not ever having it. im really having issues with samsung working with the NSA for this crud

    I flashed the Knox free ROM described in the Truths and Myths About Knox thread, it seems to have worked for me.

    did you flash a bootloader. or just the rom? and did you have knox to begin with (from the OTA update)?

    Be careful, that headline is extremely misleading (not to mention the article was rather poorly written in my opinion); Knox CANNOT be removed, you can only bypass it or disable/remove the associated apps. There is a distinction between the bootloader itself and the apps that function with it.

    Knox IS a bootloader that runs before the "bootloader" that we are familiar with. It is FIRMWARE that is installed into a dedicated area of the processor itself. It CANNOT BE REMOVED, PERIOD. Someone like Chainfire or another very, very skilled developer may perform another miracle but in the meantime, we really need to realize that it's a very complex, highly developed system that has nothing to do with preventing us from rooting. Its purpose is to establish a chain of security that ensures Knox enabled apps are completely secure, and enclosed in an encryption shell when they START. The easiest way to break into a bank is to hide inside when everyone goes home. Once installed, Knox will ALWAYS be the first and only one inside...

    Knox has a public key and a private key unique to PROCESSOR it is installed in. It creates a unique signature of the device then validates the bootloader as "signed" by Samsung. From that point forward, it will always know if the bootloader contains a valid Samsung signature. Any, and I do mean any changes to a stock bootloader will be detected by Knox and it will react. It first needs to stop/prevent (re)creating the encrypted shell for Knox apps and it also needs to protect anything proprietary that remains on the device., encrypted or not...

    This is where we have a lot of questions, and a lot of rumors, and probably not a single fact available as to exactly what it will then do to "our" device. In a few years there will be trillions of dollars worth of proprietary data floating around on personal devices of all kinds. Samsung and every major manufacturer will have way more invested in this than any of us can probably imagine.

    The bottom line is that we should spend time helping each other deal with it, and not keep bashing it and thinking we can outsmart it. In other words, let's learn what it does and how we react instead of what to do TO it. It's a fact of life now.

    Sorry for the rant. It certainly isn't directed any individual. TheBritton posted an excellent link a long time ago to Samsung's public explanation, actually their marketing of its purpose and value. It is a good read. Ironically, it's purpose is to let you do whatever you want with your personal device even when that same device has access to all of your bosses secrets (BYOD) .

    quess I need to order another gs3 chipset, and swap out the internals entirely, to work, like changing the phone, but keeping the case, or taking out the chip on the ouya, that was easy, but the ouya, is slower than this phone trust me, tegra 3 sucks, especially with only one gig of ram

    let me be clear all chips and phones released after the invent of knox will have it.

    Knox does not stop you from rooting,flashing roms,or custom recovery's. what it will do

    is brick if a non-signed bootloader is flashed or an older bootloader signed or not.
    once triggered the bring your device to work stuff will not work.
    once triggered your warranty is void depending on service center policy. but rooting did that anyway.

    there is no way to remove the 4.3 knox'ed bootloader once installed you can of course upgrade to an official on if ever released.

    you can remove the apps and other rom based knox items in the zip if you know your stuff.

    Flashing custom roms: need to of course have the assert lines removed or edited for the vm edition but you must also be careful not to flash one that has a bootloader.

    for anything refer to the knox truth or myth thread.

    Okay so to chime in here, on a technical level, it is possible to remove. You would have to buy about 200 dollars in JTAG equipment but it is an option. Basically you take the bootloader dump of a non Knox phone, and then you flash that raw backup back to your Knox phone. This usually requires disassembly, however qhusb dlmode may work too, with Samsung private keys ;) welcome to the life of the average HTC user on Verizon or AT&T by the way

    I've not seen that at all. Most of the HTC users are very loyal actually. Even the HTC one got best phone of 2013. The reason people dump HTC is because the developers dump them when they refuse to release kernel source. :) Samsung is plastic, and very light. I do not like that myself. I'm only getting a nexus for the next phone because if I get angry at my carrier I can take it anywhere :)

    like i said i got nothing against HTC, but iv had 2 friends dump theres, my boss actually got an HTC One for free from his carrier and he brought it back in less then 2 days lol, he did that tho cause he never had a touch phone, was too much for him to handle lol, but i tried showing him how to yous it and i personally didnt like the live tiles, of course it wasent my device so i couldnt go crazy playing with it but the setup bothered me lol

    as for the sammy, i got mine on sale for $280 couldnt beat that, then i got the lifeproof nuud case for $59 couldnt beat that either lol and icing on my cake after buying them was amazon was having a massive micro sd sale so i got a 64GB class 10 for $35-$40 lol


    i wasent meaning the HTC thing worldwide, i was just part of the triumph community before i got my sammy and at least 3 of the users got HTC's as their replacements and sold them to try and buy a nexus or something else, the ones they got werent the HTC ones tho if i recall correctly, whichever one it was was having issues at that time so that could have ultimately been the reasoning behind them switching

    Ah. Well with any phone too, it's about the custom roms. If HTC helped custom roms they would be as big as nexus devices. The Google Play edition of both devices really helped, and actually the gpe of the s4 doesn't have Knox I believe

    yea i seen post on the web that knox has failed basically, spam and spyware attacks have been hitting knox only apps proving that it doesnt work at all, ive been hoping they release an update to just remove it from the phones but most likely they leave it on the S3 and only update it once they fix it lol

    Samsung will just switch to fully enforced selinux in 4.4 which means good luck rooting basically. Things will have to attack the less secure radio, as it shares memory
