Devices that don't void the warranty when you unlock the bootloader - Upgrading, Modifying and Unlocking

I know that Nexus, OnePlus, and developer edition Motorola devices allow unlocking the bootloader without voiding the warranty. Do any other devices also allow this?

[Q] Question: Rooting and Bootloader

I recently came across this article here: http://www.redmondpie.com/unlock-nearly-all-htc-bootloaders-while-sparing-your-warranty/
Basically, I can lock and unlock my bootloader at will
Warranty is voided if you unlock the bootloader, which is required for rooting, unless there's a method to do otherwise.
Is my warranty still available if I unlock, root, then relock? Because the HTC service staff says that unlocking might cause damage, but as far as I know none will be caused. But should it do so, won't relocking it make it alright?

Rooting without unlocking bootloader is impossible.
Your warranty will be void if the bootloader has been once unlocked. Relocking won't always make it better and it will display **relocked** instead of **locked**
It's not impossible though to get the phone fixed under warranty with unlocked state...

Perhaps where you are from, it is permitted. Here though, the technicians tend not to know too much about this kind of thing.
I've seen all sorts of reports. Some with unlocked bootloader have success with warranty repairs and some do not.
It all depends on where you send it back, who looks at it, what the actual fault is and the position of the moon.
I seem to recall on htcdev and the screen on the phone when unlocking say 'may' void your warranty.
Basically pot luck but not 100% no.

Seeing as it's the same thread, I'd just like to ask if there is ANY damage caused at all by unlocking the bootloader. As far as I know it does not happen.

Bootloader and warranty

Does unlock bootloader cause end of warranty? If yes could I lock it again if I would use warranty for repair?
Yes, you lose the warranty. No, relocking is not possible. The unlocking is registered at the Lenovo Servers.

Hi can you tell me how to unlock bootloader .. I am ok if it voids my warranty
Go to about phone in settings, tap build number 5 or more times (i dont know how many exactly). Go back to settings list, go to developer settings, go to unlock bootloader, follow instructions.

unlock and return to stock - warranty?

I'm thinking of returning/replacing my phone due to the issue with the screen (one side is darker).
I unlocked the bootloader und rooted the phone. Am I'm going to have any problems because of that? If I return to stock, will they be able to detect that it was unlocked?
I did find this statement in the faq:
The technical process of rooting or unlocking the bootloader does not void the warranty of a OnePlus device. However, we strongly suggest for you to only root or unlock the bootloader of your OnePlus device if you are confident in your understanding of the risks involved.
By accessing resources regularly unavailable to the software, you may damage your hardware during or after the procedure. Such damage is not covered under warranty. In warranty handling, we will first need to verify that any faulty behavior is unrelated to rooting / unlocking.
I'm still within the 15 day return period.

Just a few doubts regarding Bootloader and rooting

Hey guys, I'm new to the Redmi forums, I've been on XDA since 2012 and have been using mainly Xperia devices.
So just had a few doubts regarding this phone(bought it last week)
I read about the procedure to unlock the bootloader and everything.
1. I know unlocking will void my warranty, but can i then relfash stock rom and relock bootloader to show that the bootloader was never unlocked? We could do that in Xperia.
Is it possible to do it now?
2. Will just rooting require the bootloader to be unlocked? And if yes would the warranty be void if I unlocked the bootloader and just root the phone without flashing custom ROMs?
Unlocking bootlader procedure doesn"t void you warranty. At least in Poland
Rooting requires unlocked bootloader. Im not sure about rooting, but you can always flash offcial miui build and its going to unroot your Redmi and relock you bootloader

1. As far as I know the warranty is not void. I have not seen any such warning. But please do check from your end.
2. Rooting will need unlocked bootloader if you are doing it via the recovery. Maybe one click root apps wont. I dunno of any one click root apps for RN5 Pro
Unlocking bootloader don't void warranty of xiaomi phones its confirmed
