Warranty question

I rooted, backed up DRM keys, unlocked bootloader, then used my phone. Later, I relocked bootloader, flashed a stock FTF, rooted to restore DRM keys, then went into setting -> reset and took a factory reset from there. Then I sold the phone.

The buyer says that some apps still says he is rooted, and therefore is worried about the warranty. My question is, did it not unroot while doing a factory reset? What should he to to unroot? And if it does unroot, is the warranty still valid?

Thanks!

He has to replace an ftf. File.
You just did a factory reset. You can't uproot like that's cause root apps write on system partition which is not affected by factory reset from settings.

If you restored DRM keys then warranty should be still valid.

Warranty is still valid wether rooted or not, if bootloader is unlocked that is a different matter. You have re-locked your bootloader but Sony theoretically could have a list of devices unlocked, they provide the key after all, and therefore warranty could be void.

Where is the proof that the warranty is valid while the phone is rooted? I can not seem to find the source

An FTF might be a little troublesome for him, as he is not technical enough for that. Would installing SuperSU and then doing a "Full Unroot" fix the problem?

Theoretically it will work. I don't know though if it leaves any traces.
If he doesn't want to flash ftf then the easiest way is to make a software repair through PC Companion

From what I know if it is rooted then also it voids warranty. Anything that gives you access to system partition could be a good way to brick phone. Therefore it is a good way for any manufacturer to deny you warranty.

Alright I'll ask to have him try the Full Unroot option first.. then go on to either FTF or software repair.
