I had a galaxy S3 lte and when it was running jellybean 4.1 it did not have knox. After upgrading it to jellybean 4.3 it got knox enable. So I imagine an efuse materialized by thin air in my galaxy s3 lte.

That's just Knox software on s3 which could be easily removed

Regarding the Galaxy S3 variants making use of the Qualcomm chip, Snapdragon S4 SoCs have had QFuses (efuses, QFPROM) for quite a while, including for the MSM8960 (the chip used for the S3; there is more info on XDA regarding the MSM8960 here). So they were there already, they were just not being used at all, at least not for the old "warranty void" flag/flash counter. But with a firmware implementing/enforcing KNOX, on a Qualcomm device including the S3 (and S4, and S5) , flashing a bootloader or recovery not signed by Samsung will indeed trip a permanent bit that will be impossible to reset. For the S3 (and the S4 variants that came out with 4.2.2), you had to downgrade to an official firmware not implementing KNOX before you could flash a recovery and not be afraid to trip any efuse <= Can't be sure about that, it's been too long. Unfortunately, for the S5, there exists no such firmware.

We agree it sucks, but wouldn't you feel bad when your device has a hardware fault and you can't get a replacement coz your warranty is void due to the bloody knox? aaaargh I feel so bad about it..it's my fault I should've tested the phone thoroughly for at least two weeks before rooting it.

Will towelroot help me get back the knox counter??

Why not just jump on ebay and order a replacement fingerprint sensor for around $12 AUD, remove the old one and install the new one? Takes about 30 mins and very little knowhow to change, youtube is your best friend with stuff like that

I haven't personally see the guts of the s5 but I can tell you from past experience, it doesn't always go to plan.

On my old HTC Sensation, I had to replace the housing and digitizer and unfortunately I had broke a ribbon cable holder which meant the whole motherboard needed to be replaced.

I don't have a soldering iron at home either and buying Chinese parts is dodgy for me. I fixed the board but the digitizer from ebay was a clone which doesn't calibrate and is off touch.

My point is be very careful, these things are very small.

Samsung phones are very simple and straight forward as long as you take your time and don't rush replacing parts is quite easy. I do a lot of Samsung repairs in my shop. As for where to get the parts from you don't have to get knock-off Chinese parts, I always buy from within my country. (Australia) the parts are always genuine and have never had any problems with new hardware. Just thought I'd share some pointers with you so you don't have to spend 3 times the cash taking your device to someone like me when its not necessary

Looking at the title of this thread (new hope) reminds me of a Star Wars film......
That was science fiction too.......
I think it's the case that those phones *infected* with knox will remain *infected*......It certainly seems that it is 'hard wired' into the newer devices with no way around it......
For anybody who's not heard of XDA it simply isn't an issue, only XDA members have an issue with it (and we ARE a minority, whichever way you look at it).
Might as well get used to the fact that it's here to stay.......

I was just about to order the Galaxy S5 for myself when I read about Knox. Does it presence mean I will not be able to reset the flash counter of my phone if I have to return the phone for repair within the warranty period? I will be getting the G900H model since I live in India.

Knox is different to a flash counter though Knox is being used 'like' a flash counter by Samsung.
A flash counter (on older devices) can be reset.....Knox CAN NOT.......
Once Knox is tripped, it'll remain tripped whatever you do....and Samsung WILL use this as a basis for denial of warranty repair......
