[Q] Not rooted Note 3 returned from repair - modified, rooted, not repaired
I have a fault with my Note 3. It restarts itself, powers off, sometimes cannot power on (freezing when first Samsung logo appears), but time to time it powers on and runs for couple of minutes. I gave it for repairs to Phones4u (UK). They kept my phone for two weeks and I received info it cannot be repaired because it has been rooted and warranty does not cover it.
First things first:
- I have never rooted my phone
- nobody else had my phone in his hands without my attention (before I gave it to Phones4u repair service)
- I was using KNOX on my phone to keep data secured, which is not possible to run KNOX if phone was rooted
- I was updating this phone with original software by auto updates
- I never used something like "Odin"" or "custom Rom"
When the fault first appeared I tried to backup my data (successful). Then I decided to make a hard boot reset. Instead of pressing Power+Home+VolumeUp I pressed by mistake Power+Home+VolumeDown which took me to download mode, as I get known.
I only remember that I have seen on screen few lines which content that info (I rewrite with the help of google search):
Current binary: Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x0
Then I did a Hard Boot Reset and next day gave it to the service for repair.
Now, when unrepaired phone came back I was able to power it on and it was running for about 3 hours (maybe because it was cold or sth) untill it froze again and I had to take off the battery to restart. I installed app "check root" which told me phone isn't rooted, but I am unable to do any updates as "your device has been modified". I cannot install and run KNOX, because "your device is not authorised to enter KNOX"
Next, download mode tells me:
Current binary: Custom
System Status: Custom
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
So, I am sure that somebody from repair team has made some changes in my phone and will not confess he did it. Customer Service is not helping me and I understand they think I am responsible for this fault. I found some help in Phones4u store in Motherwell, where some girl tried to contact repairs and customer services to get some answers fro 40 minutes with no results. Finally she was advised to contact Samsung. She arranged a service for me. I will send my device to Samsung when I receive some secure bag to send my device in.
However, I know they are unable to repair my device if KNOX Warranty Void 0x1. But what I am going to ask them is, can they find in that phone when was changes made and how. That would help me identify who is responsible for that. Do you think Samsung is able to read from my phone that modification time and date and who is guilty?
