Hi,
I've unlocked my bootloader in order to install TWRP. I found a couple of references in the how-to about "re-locking" it:
"Q1: How to relock the bootloader?"
"Q3: Will it affect future OTAs after unlocking?
Secure user data partition may also become inaccessible and you will not be able to get official software upgrades if you unlock the bootloader. Once re-locked the bootloader, users will receive official OTAs again."
So, to my understending, if I want to get official software upgrades, I have to re-lock it again...
My question is: which implications does this have?
Will I lose TWRP functionality?
May I brick my device by doing so? While searching for it, I've found some messages saying "your bootloader has been destroyed" or so and I'm a bit afraid of doing so.
Which is your recommendation? Is it better to leave it unlocked?
Thanks in advance...

Hi all,
I have read many threads on this page, and developers pages, however, it seems quite difficult to unlock this O2 LT15i so I can install ICS.
I have tired and failed.
Is there anyone that might be able to spend a little time talking me through the steps to do so.
I just wish this phone was unlocked as if it was, it appears simpler.
PLEASE can anyone help, or suggest a step by step guide. (for novices like me) that really want the phone working well, but arent 100% clued up on all the softwares.
I understand the process of installing ICS to phones, as I have done so with my HTC HD2 (workked very well in under an hour). but this LT15i is something else!!!
Please help.
(sorry if this has been posted before, but I have honestly tried howevver, the guides I used have missing links, or trojans in the downloads
Kind regards
P
forgot to mention Bootloader unlock allowed says NO.
Whats my first step?
I follow all the other guides and they all have yes as the answer....

Bootloader & SIM Unlocking:
PLEASE NOTE: The ONLY WAY to Sim Unlock your Phone is to PAY for it, so do some Googling and read which services have been recommended in the past.
PLEASE ALSO NOTE:
If you're Phone was manufactured AFTER a certain date, 12W11 (look under your battery for a similar number) then the Testpoint method no longer works, and People who have had Phones returned from a Service Centre are reporting that they can no longer unlock via the Testpoint method either.
- Know Your Android Bootloader - What it is and Why it Matters
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.
Standard Unlocking:
Then there is the TestPoint method...
TestPoint Unlocking:
Two members - Alejandrissimo or Jinx13 offer a Remote Service which isn't free, but cheaper than anywhere else on the net, and when you take in to account you will also SIM Unlock and retain DRM using the Remote method it's worth it.

Hey buddy, you don't need to unlock your boot loader before you install a custom ROM or upgrade your phone to a custom firmware, all you need is to get rooted and download the ful ROM, then with the help of flashtool, your done. Am currently running a custom ROM (viper xperia) which is blazingly fast and lovely UI with my Lt15i locked bootloader.
As we were waiting for a long time to get the unlock bootloader codes from Amazon for Fire Phone,but we see that after the phone was discontiniued,Amazon abondoned us in the middle without releasing the Bootloader unlocked codes..
But one of our genious developer @pipataki is succeeded in unlocking the Bootloader Codes
There is a thread in the general thread in which he was working on lollipop update and he succeeded in that as well, there he give us this great news about unlocking the bootloader codes he also said he will make a video of that very soon...So that means now stable custom roms can be made without any camera and other issue
Video with unlocking process from pipataki..
In video, dude has done a hard factory reset if i'm not wrong and nothing relating to bootloader unlocking
This 2 guys, dont trust them. They are doing nothing

Part 2 of bootloader unlock
It says "failed: unlock code is not correct" lol. Iros a vender la moto a otro sitio

No, they aren't fake, but they aren't show bootloader unlock, just hard reset and some commands from fastboot
I don't see how a factory reset, messing with safestrap and then rebooting again into fastboot to check status constitutes as a bootloader unlock.
No codes, no news, no unlock...no open thread.
Thread closed.
OP, please press report when you have real content to share ... in-house (as in, not "mime" videos on YouTube).
Thank you.
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.

This. And there are people saying the EU is a bad thing in general

Yup, Motorola, help users void their warranties outside the EU by not letting them relock again. Way to go, guys and gals
Thanks for the insightful post, FeeMale, much appreciated :good:

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.

As said before: a faulty screen, mic, button, speaker, mainboard,... has generally nothing to do with an unlocked bootloader.

It's not a wish anymore where I live. Off course, as said before: in the case the custom software broke your phone, you cannot make use of your warranty. I don't think anyone disagreed on that?

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.
I'm not having any luck unlocking the boatloader. I've read the instructions, apparently I need a code from Huawei to do it, but they stopped giving out codes... am I completely screwed? is there some other process?

Unfortunately you posted in the wrong section ... I think you'll get help faster if your question is put in the right place, you are now on a development section and no one give much importance to requests like this. Thanks !
Use PotatoNV to reset a new unlock code.It's working and free
Regarding unlocking the bootloader. I wrote to the official Oppo mail, they refused to give information that could violate the confidentiality or a guarantee. As far as I understand, modifying the system on this device or getting root - are dreams?
Oppo devices are not unlockable
