So, if I unlock my bootloader and my phone gets bricked and needs service, will I be able to use my warranty? If not, is there a way I can make the phone look like it has not been modified in any way(ex: maybe lock the bootloader again or something like that) so that I can use my warranty?
Thanks in advance.

You can simply flash firmware via miflash. Everything will be like brand new, bootloader will get relocked.

I've recently unlocked my bootloader and I wanted to re lock it. Well, I couldn't find any thread about this and I thought it would be good to open one. My question is obviously how to re lock the bootloader in Xiaomi Redmi Note 3 Snapdragon.

Did you use unofficial bootloader unlock? If you did, you're really really f***ed right now. The only way to fix this is to physically open the device, unscrew the motherboard, plug in the usb and use a metal object to connect the two "testpoints", which will force the phone into edl mode.

In that case of official unlock, guess you can take to service center and get it repaired?
For unofficial unlock, there is simple way to lock bootloader by putting back original "emmc_appsboot.mbn" from fastboot rom.
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn

Yep, still bricked. Hard Bricked. I have used tespoint again but it was actually hard to trigger it because it caused phone to restart normally instead of going to edl.
When I tried to EDL Flash my phone normally when i had access to android, I got and max memory something problem in Mi Flash and when i tried again it sent a hello package to my phone and then it said catastrophic failure. So, don't know what that actually means and I hope not what it actually says. However i still have access to fastboot mode and recovery mode but i found out that I actually have locked bootloader after flashing this "emmc_appsboot.mbn" and had the phone alive in chinese dev rom and then i wanted to roll back to global stable via edl and got brick. Sadly I do not have access to this test mode where you test your phone's sensors, display and more.

Hey, you can go into EDL mode?
If yes, why don't you flash the Fastboot ROM - Global one if you don't want CHinese one

Great! Happy to note that your phone is back.. If flash has been successful then it will work.
testpoint is risky and requires expertise right?

Actually it is not that difficult but it is extremely tricky since if you press only the left one test point it will just reboot. You need to touch them at the same time. Although you'll need to be accommodated with electronics since they are sensitive.

I had a little heart attack because I thought That i had cut the Button Cable during the flash process but THANK GOD it was right underneath the motherboard and IT NOW WORKS. YES I AM IN MIUI GLOBAL. THANK GOD. Just for you to know, every failed bootloader unlock on any smartphone is equal to several heart attacks.
I impulsively unlocked the boot-loader on my Mate 20 Pro last night because Funky Huawei was selling the codes for $20. Today I can't really think of a good reason I actually need the bootloader unlocked since I have no interest in rooting my phone and there are update methods for manually flashing firmware that don't require an unlocked bootloader. In fact, the tool posted on XDA for updating firmware with an unlocked bootloader apparently requires that you be rooted to use it.
Is there a way to relock the bootloader?
The only mention I could find in these threads was someone who said you need to factory reset the phone and then go back into fast-boot. I don't think the person who wrote that even tried it and that he was just making a generalization.
Does anyone know if there are actual steps that relock the bootloader without bricking the phone--which the e-recovery restore method might do since it will try to install an older firmware than is currently on my phone.
I might just keep it unlocked anyway but I was curious if there was a known relock method that works on this phone.

Use dload method, but pba that will erase everything like your 1st setting of your phone. Phone will be locked again, FRP will still unlocked.

does dload method altso come with recovery_ramdisk fixed? for us that have modified it for root or twrp??
So that the device becomes out of the box like new?
Yes, recovery_ramdisk back to stock with dload method

i can confirm dload method lock back the bootloader.
i had install an alternate fw but was not satisfied cause too much features were not working, i used first erecovery to download official fw but unlock bl was still present. then i try dload and phone was completly reset with bl locked.
dload method isn't working for me. I extracted the UPDATE.APP from the firmware version that is currently installed on my phone (using the update_full_base version), created a dload folder on my external card, copied the UPDATE.APP into that folder and then did the dial code and selected update from memory card. My phone reboots and then I get an error that says that the update failed.
Do I need to use the UPDATE.APP from a specific build to get this to work?
I installed firmware via the Funky Huawei method. It seems to have relocked the bootloader because the warning about the bootloader being unlocked doesn't come up when the phone boots but the data on my phone wasn't erased. Can the bootloader be relocked without erasing all the data on the phone? If so this is the first I've heard of it.

Will we able to reclaim warranty after relock? Anyway the service guys would be able to know that the bootloader was unlocked before?
Soo what is the legit way to relock the bootloader and the FRP?
is the FRP from stock/defualt locked?

Hello.
I downloaded Fastboot images of miui 12 for my remi note 9s but, cannot flash the images because the first error is something like "lock state" when Fastboot tried yo erase boot.
My device is almost 2 months in my hands and cannot unlock bootloader because I will loose warranty.
Search Google but there's a lot of similar problems with other models too.
Impoetant, my device ia updated to miui 12 stable but downloaded 720mb and the Fastboot images are almost 6 gb
Thanks.

You have to unlock your bootloader before flashing anything iirc, even if it's the Xiaomi approved, signed, original factory firmware. You can re-lock the bootloader afterwards and everything should be the same. I don't think Xiaomi phones have a "digital fuse" or something that permanently marks a phone as having been unlocked once (or that service centers care), but don't quote me on that.

Some saying that relocking the bootloader while in custom recovery state will cause bootloop. What's the exact procedure should I need to follow to have a relocked bootloader for RN9P? I heard that I should flash stock firmware from MiFlashTool using "Flash all and lock" option. Does it work or did it worked for anyone?

You're screwed. Verizon will NEVER unlock the bootloader, and you can't either. This means you CANNOT flash factory images. You CANNOT root the device. You CAN manually flash OTA images through the device recovery with fastboot, however as the device is still supported for the next four years, that ability is nearly pointless.
You should have purchased a Japanese Pixel 6. If I recall correctly, it's the same hardware as the Verizon Pixel 6 but with an unlockable bootloader. Now it's too late for that, so simply enjoy what you have because honestly you're not missing much.

Perform a factory reset instead. Since you cannot flash things that's the way you eliminate bugs on your device.
