Question Does a bootloader unlock on Note 10Pro blow any EFuses? - Redmi Note 10 Pro

Hello.
I want to ask if someone here knows, if unlocking the bootloader changes any EFuse states in the SOC, because Samsung does that
to prevent Google pay from working again on the device, even if the bootloader gets relocked. Now the question is, if Xiaomi does that too?
Does any one here also probably know if, and when yes, what EFuses are set on the Xiaomi devices from factory?
Regards

No.
When you relock bootloader it's like from the factory and your warranty isn't voided.

Do you know if they have "Etched" the checksum of their Bootloader into the SOC by setting the configuration EFuses, or is
it possible to replace the entire bootloader through another one (Normally this isnt possible because the SOC itself is locked
to the Cellphone manufactuerers signed bootlaoder by blowing config fuses. Does Xiaomi that too?

[Q] Unlock bootloader : Waranty Void | reLock bootloader = ??

Hello I just updated my wearable to 5.0.1 but I didn't know that it voids waranty, then I locked it (the bootloader)....
Will LG be able to see what I did ?
Because I know that on some android phone you need something called "JIZ" (?) which to erases data about that stuff.
BTW I have a dead pixel .... That's the problem. :/ I am also running a dead pixel app hoping that it will disappear, I got several choices for timing, I am currently on 0.1 , but isn't 0.02 or 0.05 more efficiency ? or is it bad ?

There has not been any verification about unlock flags or counts. We currently only know that it is capable of being relocked with the appearance of the original locked state. I know several of my phones in the past would set a visible tampered flag that would not easily go away. The current theory is that this device acts like the Nexus devices in both appearance and flagging. It only displays unlocking while it is unlocked.

In the EU, unlocking bootloader has absolutely no impact on warranty.
In other countries, you need to read the warranty conditions, but I don't think you will automatically lose the warranty either.
Some companies warn against unlocking (Samsung) but usually if the technician is sane, it gets repair under warranty either way.
Can this unlock the boot loader of devices already on 5..0.1 since the bootloader may be upgraded

Are there any risks rooting the P20 Pro?

As i am coming from Samsung, i want to know if there is any risk of loosing functions that are protected???
With sony, it were some camera functions i lost when i rooted it, on my note 3 it was the efuse etc...
So is there anything i have to worry about?

Rooting itself does nothing that you mentioned.
Using a firmware other than the one intended or flashing outside of the natural progression which was intended is what breaks those things
Samsung- efuse chip is triggered when you use Odin, not rooting.
With Sony when I had a Z1 it was using a non standard ROM or: Cm or aosp which meant the standard savers didn't work as it wasn't ported unless they really tightened up their DRM.
In this regard its the same, but the camera has already been ported, its in the ROM section of this forum, so no worry there, I don't know if there is an efuse chip on the Huawei but I do know they're funny about bootloaders being unlocked and further modifying so there may be a way for them to know and they'll probably blame any issues as a result of that regardless of what it is if they can prove it.
That being said there are reports of users who've totally bricked their phones and already have replacements so I would say it depends.
With unlocking the bootloader and modifying your phone against the advice of OEM's always carries a risk, so it's up to you if you continue.
Personally I'll do what I want with my phone, by buying it it's my choice and I'll do what I want.

No, first of All you need to do is unlock the bootloader.
I came also from Samsung, i unlocked my P20 pro and then i rooted. And i had no impairment.

Okay, thanks for your answers. So ill root mine too, got my bootloader unlock code from huawei.
I suppose you loose warranty the moment you use the bootloader code. P.s. how do you request a code?
Thx

Check out guides on this forum. There are quite a few places that explain how to do it.
For example a thread has all info: [GUIDE] - How to root debrand and/or remove Retail mode for P20pro CLT-L29

Help!!!!! Moto g6 variant xt1925

View attachment 4629305Good evening, since I upgraded my phone to OPSS27-82-87-3 version I have not been able to block the bootloader again, when loading an image it says boot loader error security patch I need someone who has this firmware since I could not block the bootloader of the phone if I do not have this variant, and this link does not work up to 222 Mb and it falls
https://rsdsecure-cloud.motorola.co...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
so download wherever it always generates the same download error
link of the image https://ibb.co/i2tV5q
I need the September patch security firmware opss27.82-87-3 a link that works, without this I can not go back to relock bootloader
Why are you trying to relock your bootloader? And you are not likely able to relock the bootloader. Sometimes flashing the exact firmware already on the device re locks the bootloader but not every time. There is no reason to relock your bootloader. It will not make the device as it was never unlocked for warranty purposes. It will not stop Motorola from being able to see that it was unlocked.

You can do it but there is no point. If your thinking relocking the bootloader will get passed a Moto service center and or sending it in will pass there warranty check your mistaken. if you do a logcat and look through it you will eventually find in the logcat it says your warranty is void. Also requesting the unlock code and using it voids your warranty. each phone has a unique unlock code only made for that phone for it's bootloader. For example me and a friend have the same Moto g6 play but his bootloader unlock code is not the same as mine. Long explain short Your warranty is voided the second you unlock your bootloader it doesnt matter if you relock it. And you can't hide it from moto. And as to what @madbat99 said. There's never been an instance where re-flashing stock firmware at least in my experience has relocked a bootloader for Motorola devices. Not saying your wrong I just personally have not heard that or seen it happen yet. it still doesn't matter though because the warranty is still voided from doing it the first time. I've heard of that happening with some Samsung devices but the warranty was still voided. I'm not sure why people think relocking the bootloader is necessary it doesn't affect the phones performance when It's locked or unlocked

Also, with the patch version of July security if I could block the boot loader

Has anyone returned their phone after locking the bootloader?

Hello there, I was just wondering if anyone returned their Asus Rog Phone 2 for repair or simply returned it after relocking the bootloader.
On XDA there is a great guide on locking the bootloader here https://forum.xda-developers.com/rog-phone-2/how-to/guide-convert-cn-to-ww-rom-26-08-t3961042http://
So would be interesting to see if locking the bootloader is all we need to peacefully rma the phone or does asus have some other sneaky peaky something going on to detect if we ever rooted.
I am perfectly happy with my phone its just some people on my youtube channel were asking if its safe to return after relocking I just said I haven't heard of anyone doing so, so not 100% sure.

Most Android devices have a record in system chip. Once bootloader has been unlocked it will change status from 0 to 1 and even if you relock the device it will still stay as 1. Since you triggered the log thingy. So Asus techs will still be able to find out that bootloader has been touched. For example on Samsung devices they use something called a KNOX chip and when you unlock bootloader on a Samsung S9 or s10 the Knox chip will break and no longer work and status will say that Knox chip has been triggered with 0 to 1. That's how Samsung finds out if you have unlocked your bootloader on their devices. So Asus have probably a way aswell on their end.
You can return the device for repair but repair service will reject warranty repair and will put a price how much it will cost you to repair the device. Since they will see bootloader has been touched. So then warranty is voided.
I returned my 1st one because of no volte. Bl was unlocked, relocked using asus's app before the tool here was available. No issues, got a full refund.
I doubt they wouldn't repair it under warranty, unless it was actually caused by a bad flash, or something.

What Asus app did you use to relock the bootloader? I thought the only way to relock is to use a fastboot command. Asus has an apk for unlocking the phone, haven't heard of one for relocking.

Ah OK no worries. At least now we know that people can safely return or repair their phones if they relocked the bootloader properly. Thanks for responding.

Afaik in EU they cant refuse repairing faulty hardware because you tried a software mod.

Question Unlocked bootloader warranty question

I currently have OP7P, I'm planning to buy either S22 ultra or upcoming OP10P, I got to know in samsung once bootloader is unlocked it break Knox and that is irreversible, and they say it will be hard to get warranty even if later I lock bootloader and unroot stock rom.
In my OP7P after I flash stock rom with msm there is no visible sign if bootloader was ever unlocked, is it same with oneplus 9 and 10? And is it correct that service center will be able to find that it was earlier unlocked and they can refuse warranty?
OnePlus doesn't usually care if your bootloader is unlocked for service....
