I've rooted my phone and flash custom recovery etc. I can unroot, reset the flash counter, and revert to stock ROM.
However I can't reset the KNOX counter as it's apparently an "eFUSE".
I took my phone to a Samsung Repair Centre today after doing all of above, I showed them my battery but apparently they needed to see the phone as well apparently to login with Samsung or something to verify they'd pay them for the replacement battery.
I chicken'd out for fear of them detecting the KNOX counter and ended up buying a knock off Samsung Battery for £14.99 of a merchant.
Does anyone know of a way to possibly just send the battery to Samsung and get them to send a replacement (without the phone)?
Also out of interest if a service centre detects custom software on the device of any kind can they refuse to give it back to you?
Thanks in advance,
