I'm confused as to what voids my warranty and what does not. I know rooting and custom recovery does not but would a custom os or kernel?
No, not on the OP5. You can always return it to stock and lock the bootloader and there's be no way of telling it had been altered. As long as you flash the original recovery and Rom you can unlock the bootloader and install custom Roms and kernels and recoveries and noone would ever know.

If I locked my bootloader, can I update SuperSU (zip) or TWRP (img) using TWRP --> Install?
I'm already aware that it won't allow me to flash custom ROMs, custom recoveries or use fastboot commands.
What does having a locked bootloader prevent me from doing?
Thank you

The better question is why would you have a locked bootloader? If you have any kind of boot loop or error you will end up with a paper weight that will have to be sent off for repairs when its easily fixed with an unlocked bootloader.

You're right about having a boot loop problem but isn't the phone more secure with a locked bootloader though? I read that it's recommended that you relock the bootloader if you're done making modifications so that no one can do anything malicious with your phone (to some extent).

I would say it's much more likely you brick your phone due to having a locked bootloader than someone else getting their hands on your phone and actually having the knowledge to cause trouble for you.
to relock your bootloader you must have FULLY STOCK firmware back on your device, relocking with anything in the phone being custom can result in a paperweight
Having a rooted phone is more vulnerable than a unlocked bl phone. Dont lock bl back unless you are full stock (I would still say dont though)

It's more secure, sure. But if you take care of your phone it doesn't fall into the wrong hands. Plus, if you have TWRP installed still a tech savvy thief (one who understands what a locked bootloader means) can easily flash a ROM and boot into the phone. As sometime else pointed out, the chances of you ending up with a brick are higher than the chances of someone getting your phone.

Ok that makes sense to not lock the bootloader. Thanks for the information everyone!
Hello,
I'm still pretty new at this. Basically, I just want to update to vanilla Nougat.
When you unlock your bootloader, when restarting the device you always get a warning screen warning you that the device has been modified.
Can you unlock -> twrp -> root -> flash -> lock?
This way, you're on an updated/custom rom and you don't have the warning / error message?
Thank you in advance!

i think it will only go away when you flash a stock rom, if you manually relock your bootloader the message will stay. but flashing a stock rom will lock the bootloader instead of relock

Unlocking bootloader will losse the warranty right? after flashing stock rom it will lock the bootloader again. but the warranty is still voided?

i'm not sure, but i think you have your warranty back if you flash the stock rom.
it seems you even keep your warranty after unlocking the bootloader, as long as there are no problems to be found related to software modifications. so you should be fine as long as the phone is running a stock rom
Hey guys,
want to mod my freshly bought Mi A1 to the max, but I'm not sure if i should OTA first or better start modding right away?
I already unlocked the bootloader and it didnt wipe it - it also has 7.1 installed still. Generally I'm usually reluctant to do official updates because they usually make modding harder - but I tried booting the treble TWRP installer .img through fastboot (without installing it) and it failed because some partition was missing it said.. so I just want to hear if OTA is necessary to use the latest custom roms or if i can keep the old bootloader etc?
Would be cool if someone who knows could say smth about that.
Or is updating through OTA actually recommended even when not planning to ever use stock roms?

If security matters for you yes
The only thing you'll share with a custom ROM is the bootloader
Since may update locking or relocking the bootloader will wipe your data
It's your choice
but it will still work as easy as before to unlock/lock with just a fastboot command, right?
and will a custom rom work with a locked bootloader? Like first unlock, install custom rom + kernel, then relock?

It will always be that easy to unlock and relock the bootloader
No don't relock on anything that is out of stock (custom kernel , magisk, custom ROM etc) this will lead to a softbrick and you'll have to be on edl more to reflash a stock rom
What's the interest of having a locked bootloader with a custom ROM? You won't pass the safety net anyway
Just keep it unlock
You can do ota with an unlocked bootloader

hahahaaa exactly the point :laugh:
well once you have everything "perfectly set up" updates can ruin it. but yea relocking the bootloader really was a stupid idea - it was the idea to make it tamper proof but since custom kernels wont boot with locked bootloader that wouldnt work.
Hey there,
I've read about GooglePay not working after unlocking bootloader. I don't know if I will ever use GooglePay but I want to know if I can go back to stock (lock bootloader?) some day after unlocking to start using GooglePay.
Cheers
Google Pay works even with Magisk.
But yes, you can lock your bootloader again with adb/fastboot ot Mi Flash, when you want.

Can you lock your bootloader again after installing Lineage?

You can relock BL only if you first go back to stock
Locking BL pulls low-level Factory reset (not sure would it even work if you are on LN or other custom ROM and/or custom Recovery or would it simply brick your phone that you will need then paid assistance with EDL account to unbrick)
(Besides, what would you do then in future if you lock BL when you have LN - you would never be able to unlock again because you must be on stock for unlocking. And with relocked BL you would not be able to flash anything anymore)
Thank you for this explenation,
Hello, is possible to have magisk without root or unlock the phone?
And if i root/unlock the phone , i loose the guaranty or not?
Thanks .
You have to unlock the bootloader in order to flash Magisk, there's no way around it. You also cannot relock after flashing it unless you want to hard brick your device.
You shouldn't lose warranty doing so, and anyways you can always relock the bootloader (only after reflashing the stock fastboot ROM!!) to restore your device to its original state.

Excuse me for insisting, but xiaomi does not void the warranty once the root phone or unlock?
why do you want magisk without root? it's pointless.
you have to unlock bootloader to root and take advantage of magisk
you loose warranty when you modify, but it depends - sk.etimes service don't care about mods

Well, there's conflicting statements about it and it may also vary depending on which country...
Anyways there's no permanent "Samsung KNOX"-style trigger in this phone at least. Flashing the stock ROM and relocking will bring it back to its original untampered state (well at least if you didn't wipe efs or persist) so they may never know it was ever unlocked/rooted.
