Samsung Galaxy S6 permanent network lock

[Anonymous]

Hi,
Newbie seeking some advice. Recently bought a Samsung Galaxy S6 but had to return the original one due to a fault. When I sought an unlock code for the new device I was sent the unlock code for the original device by customer service. I entered it thrice without realising the error which led to the phone becoming permanently locked to O2. I have since received the right unlock code but keep getting 'nerwork unlock unsuccessful' error on using it. Have been it touch with Customer Services who have not been very helpful (quite rude and aggressive in fact) and have told me there is little they can do. I travel frequently and have to unlock the phone for use abroad. Although I have lodged a complaint with O2, I doubt it's going to get me anywhere so I was wondering if experienced members are aware of any fixes for the problem? Is there any point in approaching Samsung directly or perhaps an unlocking service on Ebay etc?

Thanks in advance

Kris

I am so glad this is sorted. I don't understand half of it... but it has made fascinating reading so thanks for that.

Tripping the Knox Counter/rooting in itself shouldn't void the warranty according to this

Is that article still valid though @Anonymous It was published in 2012? I know that it does cause problems in the UK when a Samsung phone goes for repair? I am sure @MI5 will confirm this...

Edited to add I am not knowledgeable enough in such matters to mount a 'discussion' on this....but I am sure others are...:smileywink:

All I will say is, why have an indication that the knox fuse has been tripped if it wasn't relevant to something?

[viridis]

Key word there... fuse.
By performing this software alteration you have damaged a hardware component.
Legally they are covered to decline, morally.... we all agree on the morally.

So am I right that even if you don't activate Knox on the handset, it will still trip?

[MI5]

Yep, any rooting or downgrading of firmware will trip it.

[viridis]

Yes, knox software is a different thing to the knox counter.
Knox security software is encrypted apps and filed with higher security features.
Knox counter is a fuse that will blow of you alter the rom or root of the device

[jonsie]

Right, so do I activate Knox or not? Never felt the need but is there anything to be gained or lost in using it?

[MI5]

No need for a personal phone.
It's geared towards business users.
