Rooting and flashing custom software on the Galaxy Note 3 causes hardware damage. Say what?

Well, it looks Samsung is following in HTC’s footsteps and finding ways to make it hard for users to root and flash custom software on its devices. According to well-known developer Chainfire, the Galaxy Note 3 comes with eFUSE technology for the KNOX security suite. What is eFUSE? Well, it’s a technology that allows reprogramming a read-only memory chip in real-time, even though such chips come with hard-coded code that cannot be generally changed after manufacturing.

When flashing unofficial software on the device, the status of the system and KNOX is switched to CUSTOM while increasing a binary flash counter, which helps Samsung find out whether the device has been tampered with. However, while Chainfire’s TriangleAway app has let users switch the status back to official and reset the flash counter until now, the KNOX status is based on eFUSE – basically, once you flash custom kernels or root the Note 3, the KNOX code gets rewritten, and this constitutes hardware damage.

Apparently, Samsung service centers have been instructed to check the KNOX status, which if tripped will void all warranty. Chainfire mentions there is a “possible hack to reset the write protection on the flash storage so we can reset some values,” but says that it will be difficult to write and has little chance of working even if it gets written, so it looks like those wanting to tinker with their Galaxy Note 3 will have to void all warranty at this point, or stick to Samsung’s official software.

After the region lock (which has been bypassed by Chainfire), this is yet another stupid stunt Samsung has pulled off, one that is going to make things difficult for the development community and for everyone wanting to get more out of the Galaxy Note 3. We’re sure Chainfire or another developer will find a way to get around the KNOX status issue, but for now, it’s best to stick to the default software.

Here is Samsung UK’s official stand on the matter: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Dear ******, Thank you for contacting Samsung Customer Support. I am very sorry to hear that you are not clear on our Warranty Terms. I fear that you are jumping to conclusions based on what you have read on the internet. I can confirm that you have a Warranty on your S4 for 2 years from the date of purchase. This can only be made void only for the below reasons: 1) If there is any physical damage to the handset caused by the user. 2) If the device has… Read more »

if you flash it and need to use the warranty just microwave the phone for 4 5 seconds then wish them good luck to check the counter or any thing on the phone and you just say you charged it, it got hot and now it wont turn on.

And they will give you a new one.

easy as one two three..

This and the region lock will only help sales of the Nexus 5.

Samsung is making a lot of bad decisions alienating the people that buy their devices or looking to switch brands.

How will they shoot themselves in the foot next week?

I’ve been living in Seoul for a number of years and sometimes need to scratch my head and ask where’s the common sense and logic to that using my western educated mind.

I am using stock firmware and allways suppose, that this remains the best choice. But even in this case I think that we had heard enough to think twice before byuing another Samsung’s product.

i think samsung should know, not everyone like stock theme..always the same, from low end ’till high end device..many android user gain root access to change this, not just theme also apps doesn’t use full for some user can’t be remove without root access..’cause it’s installed in system apps..not user app so user can uninstalling without root access..from pass 3 years i see many app is push to system app..some crapp apps..

Seems to me the time is ripe for another manufacturer to catch up with Samsung and rise. Who will it be? HTC/Lenovo, Sony… Huawei even? Samsung had better remember quickly how they got popular in the first place.

I own 3 Samsung tablets and 4 phones. Applying eFuse crap means end of Samsung over here. I intended to buy a Note 3, but put that on hold. Better wait for the Nexus 5. Samsung has decided to commit suicide.

Well this seems to affect only the KNOX secure mode and will not make the phone not function. However voiding the hardware warranty by changing the software sounds very similar to upgrading to a different version of Windows or switching to another OS on your PC. Why can this not be allowed?

Here’s the thing, rooting would allow you to overclock your phone, and if you try a BAD custom Android version on your phone, it DOES have the potential to cause damage. Now, if you want to be covered by the warranty, or insurance, you should stick with the official firmware, and if you choose to take the risk, don’t go crying to Samsung, or the carrier you bought your phone from saying that the phone is defective. If you modify your own car, you run all sorts of risks, and in the process, you basically say that anything that happens… Read more »

Thats no argument. A PC is rooted by default and has warranty.

Your silly to not have rooted your S3 bc of that…. Have you ever even tried to turn a phone back in that’s rooted? I think you’ve been basing your bias on speculation and fear… I don’t mean for any of that to come out rude btw I just want to let you know that I’ve had the S3 since day 1 it came out and I rooted it the 3rd day I had it… I’ve dropped and broke the charge port one and the screen before and Asurion replaced it both times without question… I EVEN LEFT THE CUSTOM… Read more »

Totally agree with you. There’s no reason for them to fix a phone which was modified.

In the UK at least (and I believe in the EU also) the warranty is: 1) provided by the retailer, not the manufacturer 2) defined by statute law, not by the retailer/manufacturer’s T&Cs It is beyond the powers of any company to rewrite the law of the land, so they can publish all the T&Cs they like to try to void your warranty, the law of the land still stands sovereign over them and that law give you a warranty. However, if the fault is as a result of the modifications then the retailer would have a case to say… Read more »
