Unlock bootloader, flash twrp, flash the global zip mentioned several times in the forum. Better with EU chinese ROM as more features than global

Thank you, but I saw the EU version of the ROM, can not re-lock the bootloader, do not know if there will be anything bad.

Correct. If you try and lock the bootloader on the EU Chinese ROM or Global it's good bye phone.
If you don't unlock bootloader you'll be stuck on the Chinese ROM forever.

Well what? If they want to lock the bootloader they can lock the bootloader.

That doesn't answer why! if it bricks the phone it might be useful to understand the process a bit fuller. I'm buying the Chinese version myself so want to be aware of why you'd want to lock the bootloader again

Return to stock, to sell, improve security, warranty etc
You'll only brick it if you install and lock the global ROM on a Chinese device, Chinese rom on a global device, or lock on the Chinese EU ROM

Cool. So if I get the Chinese one I'll put the EU one on.
I don't think I'd need to worry about locking the bootloader for a long time. I want this phone to last a few years and it seems reliable enough. And the processes will improve all the time.
Thanks!

Locking the bootloader is for certain applications and features that requires a more "secure" phone, since an unlocked bootloader is considered not "secure".
Payment Applications, Banking Applications, and DRM applications (Netflix) and such requires the phone to have a locked bootloader, or it will not work.

Are you forgetting Magisk? I'm unlocked since surviving 72 hours of stock locked hell. All my banking apps and Google pay have worked for the past 2 months.
BTW stock Chinese or Dev or Global are garbage compared to the EU version anyways.

Relock G6 Play bootloader

Ok, I tried about every method and every stock rom I found on the net in order to relock the bootloader for my XT1922-3. And whenever I try to lock or unlock the bootloader I get the message "invalid boot state" and the next line read "OKAY". The bootloader remains unlocked. Bootloader shows "flashing_unlocked". Please, can anybody help me? I really don't know what else to do.

There's no point in relocking it plain and simple that's why you haven't found anything about it. Even if you do relock it for the purposes of trying to trick Moto it literally tells them in the logcats it's been bootloader unlocked. Also once you request the key and use it it voids the warranty which Moto also knows about. If your trying to sell it just be honest and tell the person it's bootloader unlocked but it doesn't effect the phones performance

I was just worried that something has gone wrong while unlocking. Thanks for the reply!

It should be possible to re-lock it like this (connect to PC in (stock) recovery mode --> fastboot oem lock begin --> flash stock ROM --> fastboot oem lock).
Also according to Motorola.
However it doesn't work on my device (XT1922-3). It returns confirmation messages with no single error, but it seems to ignore the command as the bootloader is still unlocked and still allows flashing other ROMS. I haven't seen anyone who succeeded in re-locking their Moto G6, except this person, although the same method is used.
General info:
- Motorola claims that just requesting an unlock code already voids the warranty (boooh!), except for the so called "Developer Editions". This however is a false statement if you bought your device in Europe, even if your bootloader is unlocked and have a custom ROM installed (they are required to follow the EU directives which means they can only withdraw the warranty on this basis when they can proof that the damage is caused by the custom software). I don't know about other regions.
- When unlocking a Motorola-device, it will be permanently detectible that it has been unlocked, even if you re-lock it afterwards. I've read that they use eFuses for this (clearing a value (possibly outside the partitions) or in some cases physically burn a small fuse). For restoring an eFuse you would need to know its initial value and set it again (generally not possible through known interfaces like USB,...).

Motorola doesn't even provide stock images for the XT1922 on their unlock support page. I assume they simply don't want users to relock their devices

So, giving the person making that statement the benefit of the doubt, s/he probably didn't unlock an XT1922-3.

What? Why would they let you "re do" your warranty, when they tell you it's void as soon as you request an unlock code ? You can do all manner of stupid crap to brick your phone with an unlocked bootloader.
It allows you to try to flash the wrong firmware, to downgrade sensitive partitions (bootloader, gpt, etc) which would bork security updates and all manner of crap as well as bricking.
And they should allow you to re-lock and indiscriminately let you just warranty and rma your stupid mistakes?
We all wish they would but...
You know the risk when you unlock. They clearly tell you on Motorola's web site, as well as all posts on XDA that show you how to unlock your bootloader.
And you think you got cheated somehow? Geez.
Follow their rules if you want your warranty. End of story.

Reality is that in 99%+ of the cases bricking a phone is done by dropping it in water or on hard surfaces,....

In reality mostly the opposit happens. Many users with stock ROM and locked bootloaders are exposed to potential security risks, because they're not getting updates anymore after a while, or none at all (Motorola = 2 years). An unlocked bootloader and optionally a custom ROM can solve this.

Motorola smartphones are quite unique in this matter. My other phone didn't had a locked bootloader by default. I'm more secure with the latest Lineage OS than the older stock ROM. And this doesn't void warranty, even if bought in the US. Laptops/PCs all have unlocked bootloaders. Using custom software shouldn't void warranty. It's not so strange…

Yup, fortunately for us, here in the EU consumers still have rights. Motorola can put whatever they want in their policies, but these don't trump our rights. IMO it's a strange - even dangerous - statement that anyone needs to agree to the biddings of a private company to keep their warranty. This warranty is granted us by LAW. Why would anyone argue in the favour of a large private enterprise anyway? We need to be protected from them, not the other way around.

It's the same in the US. It falls under the Magnuson-Moss Warranty Act of 1975, which was ruled to apply to smart phones in 2015 by the FTC. We can run 3rd party software all day long and it doesn't void the warranty. You root and the headphone jack craps out? It's covered. You root, run an overclocked kernel and burn up the cpu? Then they'd have to prove that whatever you did, broke the phone in order to void the warranty. If they can't, they gotta replace it. They won't even look into it at that rate. It isn't worth the cost of litigation. It's cheaper to just send you a new one.

Get Warranty back again

Hi guys,
I'm using Gingko MIUI11 official with Bootloader unlocked and rooted, also Orange fox installed. As per invoice my device is still under warranty. But as I've unlocked bootloader, give root access also using a custom recovery what should I make sure before visit Service Center. As I'm facing proximity sensor issue and I've troubleshoot and found its hardware issue. So before visiting service center do I need to clean flash official MIUI again, lock bootloader again? Any suggestion please. As its my primary device I just don't want to clean flash. Is there anyway or advice? Or there is nothing to do
Regards

The only way to get back under warranty is to clean flash and relock bootloader

Question POCO F3 Warranty

If I use ADB to remove bloatware on the F3, will I lose my warranty? Is the Xiaomi ADB official (from Xiaomi)? Do I also lose my warranty if I unlock the bootloader and install a custom ROM? If not does Xiaomi say so on their website? What is the difference between using ADB and just deleting them manually? Thanks!

You will not use your warranty by using adb to remove bloatware. However you do waver your warranty by unlocking the bootloader to put a custom ROM on it. However you can theoretically still get a replacement despite this wavering of a warranty

You should be find. I have never had a Xiaomi and so didn't know how supportive they are. The official advice by Xiaomi is here:
What do you need to know about unlocking?
First and foremost you can only unlock your own device. This means the unlocking tool you downloaded must be logged in with the same Mi account on your device. One Mi account could only unlock one device within 30 days
Isn't locking bootloader against Mi's 'geek' spirit?
Locking bootloader is aimed to provide a better user experience, which we've been trying to do the whole time. In the meantime, we've provided an unlocking tool for senior users who know their ways around flashing and tweaking their devices.
The unlocking procedure will need Internet access to get the unlocking password. Also, the Mi Account logged in on the Mi phone and the unlocking tool needs to be the same. Otherwise, the unlocking request will be denied. This will ensure that ill-intentioned people will not get access to your personal data.

Read step 7 and step 20.

Honestly the biggest drawback is that generally no L1 support after unlock, but in this phone that doesn't happen, so I would say No drawback at all

Ok thanks. I was thinking of trying miui but I didn't wanna wait 7 days once I decide miui isn't for me. I will unlock as soon as I get the phone

No, you must wait 7 days to unlock after you submit the request to unlock bootloader. So you still need to bear with MIUI for at least 7 days.
There's no shortcut (yet).

Most banking apps will not work with unlocked bootloader. This apps consider unlocked bootloader as a root of the system, so a lack of security.

Firstly is SafetyNet check. This is the first thing for banking apps.
Some ROMs did not pass SafetyNet out of the box and they have to use Magisk and modules to make them pass. This kind of ROMs mostly will have issues with bank apps.
To sum up:
Bootloader unlock: you can use bank apps, but sometimes not.
Root: you can use bank apps with some adjustments, but sometimes not.
ROMs: you can use bank apps, but sometimes not without the help of Root.
Try and error, life is just like this.

That is not totally correct either.
There are many cases that people had installed custom ROM and bricked their phone, but Xiaomi still give free warranty within the warranty deadline.
If you installed custom ROM and need Xiaomi warranty, simply return to MIUI and you still get Xiaomi warranty within deadline, if the policy said so.

As I said, some bank apps can work. If ur bank app does not work, then the only way to use it is to root the ROM using Magisk (and some other specific magisk modules have to be installed if installing magisk only does not do the trick).
