Asus can't see I flashed my device in the past if I have stock ROM with locked bootloader, can they?
Can anyone tell me how this works exactly?
Everywhere I read I MAY risk to lose warranty.
Thanks in advance!
No (well...can go either way)
Yes (although you don't really lose it in the first place)
Once you've flashed the factory image and relocked the bootloader, no they can't (only Nexus to have a tamper flag is the N5)
That warning is standard on all unlockable devices. It's a standard disclaimer they put on there just like any other company would (to cover their butts). However, I do see where the company is coming from. I've seen noobs unlock and start flashing, and then end up messing their device up beyond recovery. They then feel they have the right to get it repaired free of charge. If you know what you are doing, chances are good you'll be fine. If something is actually defective, and as long as you still have to ability to flash stock image and relock, you're good. That being said, I've also read stories of people getting RMAs successfully even though they were unlocked/rooted/ROMed. As long as you can make a case that the defect wasn't caused by your own doing, I would imagine you'd be okay.
