Just a few doubts regarding Bootloader and rooting - Xiaomi Redmi Note 5 Pro Questions & Answers

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
Changes in rom may void warranty like rooting
But u can again clean flash rom with mi flash restore to factory stage is possible

[Q] Rooting and carrier warranty

I need your help guys,
just got my Xperia ARC and i wanted to root it by this guide and i have a few questions:
i bought the phone from an Israeli carrier (pelephone if its matter) so in the guide i need to change the carrier firmware to the original firmware and i wander if it will void the warranty. also is there any way to change back the firmware after the change, if so then how? i searched and i couldn't find anything...
thanks ahead
The thing with Rooting a phone, is that you can root your phone and still the ¨stock¨ Arc is untouched after you have unrooted.
The flashing and rooting dont break the warranty by it self.
If you change from locked bootloader to unlocked.. The warranty is removed.
Easiest way to root is:
*Download*
3.0.A.2.181 Generic World: http://www.mediafire.com/?​y9s73andrl4bllc
*Use Flashtool to Flash .181*
Flashtool: http://www.multiupload.com​/7H4JT35B6G
*Use Gingerbreak after you flashed back*
http://forum.xda-developers.com/show....php?t=1044765
*After it have rebooted and active, go to settings and do a OTA over wireless.
This way you keep your Arc locked, nothing good comes from unlocking the bootloader yet.

That's not entirely true. You've got custom ROMs being developed; over-clock kernel just released, Recovery and what not.
Unlocking the bootloader is personal choice. I may not unlock my bootloader just yet but I can't deny that with improvements being shown, it's an increasingly tempting option. LOL!

[Q] Arc Root

Well It looks as if I Cant remove unnecessary apps on my Arc without rooting.
But here is something i wanted to ask before I go ahead with doing That
Q1) Is it necessary to Unlock My Boot Loader for Rooting or Rooting can occur without Unlocking it aswell?
I mean that I have read rooting without unlocking it but will it be the same locked or unlocked?
Q2)Unlocking My Boot loader means a 100% surety that my warranty will be Nulled right? (I Live in India, Rules don't differ here or in UK does it?)
Q3) If I have Rooted and NOT Unlocked my Boot Loader, Can I still update my Phone software through SE PC Companion? And Is my Warranty Still Safe?
Because I read that ICS will be available for Arc in the first quarter next year so I want to update my phone using SE PCC and NOT by flashing even though I know the pro's of flashing
Thank You so Much!

1. No you dont have to unlock BL to root your arc search for doomlords easy rooting toolkit
2. As far as I know yes
3. Yes you can still update with SE PC companion but I think updating via PC companion removes root. And your waranty is safe
You can use zegrush to root without unlocking bootloader. I live in India too. U can still update after rooting but not after unlocking. Rules apply everywhere.
Xperia Arc (rooted)
Thank you sooooo Much!!!
One more question
@Tatit1011- in reply to ur question 1, are dere any pros/cons of rooting after unlocking BL and. Rooting without unlocking it??
Sent from my LT15i using XDA App
If you unlock your bootloader you CAN: flash custom roms, kernels(for overclock), and generally anything.
You CAN'T: upgrade via se, either pc or ota via the phone. Plus drm is lost, as is your warranty, but you can re-lock it
Generally, if all you want to do is remove system apps and use apps like titanium backup, root explorer etc then just root. If you want to try custom roms(there's only one you can flash over stock kernel, I think) then unlock the bootloader.

How to root ZUK Z2 without unlocking bootloader?

Is their a way to root ZUK Z2 without unlocking the bootloader first? I don't want to unlock bootloader as it will void the warranty. I figured, phone can be unrooted easily too if can be rooted without unlocking bootloader and helps save the warranty.
You have to unlock bootloader first in order to gain root access.You can relock bootloader and regain warranty after flashing ZUI 1.9.004.But don't relock bootloader on custom roms as it can result in brick.

Will unlocking the bootloader void my warranty?

Hi! I Just got the A2 Lite and would like to try some ROMs on It.
Will unlocking the bootloader void my warranty?
And if yes, Will re locking It get my warranty back?
Thanks in Advance
Unlocking the bootloader supposedly voids your warranty, but AndroidOne devices have no protection like Knox (which trips if you unlock BL), so there's no way of knowing if it's been unlocked before. Just flash the stock firmware via MiFlash and lock your bootloader before sending your device to warranty, voila. None of the roms I've tried work as good as the stock one though, I'd suggest rooting instead of changing the ROM. Have a nice day.
Very Good Answer Mastonpear...
