Hello everyone. I just got I'm mate 9 and I'm totally psyched. Seems like it's one of the best phones out there currently. I know I will be spending a lot more time here from now on. Looking around and doing some searches, I found a few threads that sort of answered this question but I'm still not a hundred percent positive. I have a couple of questions as follows:
1) I know that the bootloader unlock process has to be officially done through Huawei. My first question is when I request an unlock code, is my warranty void after that? Do they have a list of people who have requested these unlock codes that would be denied warranty even if the bootloader is locked when and if the warranty service is requested?
2) if the bootloader is re locked, is there any way for Huawei to tell that it was ever unlocked thereby denying warranty coverage?
Thanks in advance and it's good to be part of the mate 9 pack on XDA.
Going through Huawei will certainly void your warranty as they will have record of you requesting the unlock code (it's sent via email after you provide your IMEI). There's an app on the playstore that can provide you the code (DC Huawei bootloader codes) that can unlock it without their knowledge and flashing an official ROM will relock your bootloader every time.

Thanks so much for that response. I was about to go through a Huawei but I think I will much rather use an app like this. It's a paid app right? And you have to use ADB to do the actual unlock.
The app is free but the service is not, I think it's 4-5 $. You'll need ADB to unlock, that is correct.

I don't really see how requesting the bootloader unlock code can be seen as a proof of actually unlocking it.
Per Huawei's unlock agreement you're forced to accept.
"Unlocking the bootloader may result in unpredictable consequences for your device, including but not limited to those listed above. The user shall be held responsible in the event that the device malfunctions and cannot be recovered. Huawei will record your unlock request information; for software and hardware failures arising as a result of unlocking the bootloader, Huawei repair centers can provide repair services charged at the standard rate for repair work outside the scope of the warranty."

Hi, I'm receiving my new Moto G this week and I've read that the only way to gain root access at the moment is asking motorola to unlock the bootloader and thus, losing the warranty.
1.Does Motorola keep track of those who unlock the device so, even if you relock it, your warranty is still void?
2.Is there any other possible way to do that so you don't lose warranty?
3. And if so, is anybody working on that? Because if there will be another way I'd rather wait until some awesome developer achieves that.
Yes because you have to submit “fastboot oem get_unlock_data" to Motorola on their website to get the unlock code for the Bootloader secondary there is a qfuse and/or a flag which can not be set to default (at the moment).
At the moment not.
No idea, i'll wait some time, hopefully there will be a workaround someday. But if i remember right there is no way at the moment to revert the changes once the qfuse is broken.
Read more the questions have already been answered.
Much of Qualcomm's security architecture is implemented using QFuses, which are software-programmable fuses that allow one-time configuration of device settings and cryptographic materials such as hashes or keys. Because of their physical nature, once a QFuse has been blown, it is impossible to "unblow" it to revert its original value.

Hi, is it possible to check when the BL has been unlocked? Or when the code was generated?

yes, when you request the code Motorola sends you an email, so you just have to look for an email from [email protected] with subject "Unlocking your Device"
Problem is that I didn't unlock it. I bought used phone that was supposed to be on warranty and it shows status unlocked so warranty is void. Seller is trying to fool me that I did this and he doesn't even know how to do it. So I wonder if I can check somewhere when this modification was made?

I would recommend contacting an agent on My Moto Care (The Help App on your Moto G) and asking if they can check according to the device serial number when the device's bootloader was unlocked. This is because to request the bootloader unlock code from Motorola the user is asked to sign in/register with My Moto Care.
Thank! I've contacted Motorola Support on chat and now I'm waiting for the date as consultant needed to escalate my case further.

Technically, no.
But on the other hand you can lock it again by flashing a stock rom using:
1. https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
2. Firmware Finder
3. Funky (Paid "service")
I'm not sure if Huawei can check if you unlocked bootloader, then locked it again using an official firmware update.
but when I unlock the Bootloader I do it on huawei site, right? So they know I unlocked my phone.
I understood I need unlock here:

You only request an unlock code, it doesn't mean you'll use it.
However,
"The user shall be held responsible in the event that the device malfunctions and cannot be recovered. Huawei will record your unlock request information; for software and hardware failures arising as a result of unlocking the bootloader, Huawei repair centers can provide repair services charged at the standard rate for repair work outside the scope of the warranty."
I guess it could mean that just requesting the code means your warranty is void.
Thank you very much for explain
Just attached to the previcous post : Huawei CAN´T Check if the bootloader was opened when its relocked again by stock firmware : Just a few Minutes ago i received my phone from Service Center. Had to switch the display ( Warrantycase ). They repaired it without asking questions.
tell me please the unlocking password that I got from Huawei .
I need put him some where in the phone?
You need to unlock the Phone via fastboot oem unlock 1a2B3etc***(Code)
Hi,
I've had a look into this and there are a few dubious looking tools out there, but it's not quite clear what is and isn't possible. Can I unlock without asking Xiaomi and voiding my warranty, or am I wasting my time looking for a way to do that?
Thanks

Short answer: maybe not
Long answer: You can try an old version of MiUnlock, but that only worked once for my old Mi 8 Lite, so i think they patched this exploit on new boards. About warranty, it will be void after unlocking it, maybe if you relock and play dumb with assistance you can get a replacement.

Unlocking of the bootloader is made available to make sure that MIUI developer ROMs can be tested by users and will be covered under warranty. Bootloader unlocking does not inherently void your hardware warranty. But a case where the unlocking results in a brick which cannot be fixed via software, the warranty will be void.
According to the statement, bootloader unlock is made available for users to try MIUI developer ROMs. And thus, it will not void the warranty of any Xiaomi or Redmi smartphone. But if the device bricks after unlocking and could not be fixed via software, then the warranty will be void
I currently switched from OP7P to S22 ultra. In OP7P I can unlock bootloader and then when required I can just take it back to stock without any sign if bootloader was ever unlocked. Now in Samsung I was reading it is not same, once bootloader is unlocked it is for forever!
My 2 questions :
1. There is no way to make it stock like bootloader was never unlocked?
2. Suppose I unlock bootloader and root it, later if I face any problem and would like to avail warranty service, and lock bootloader again and unroot it will Samsung not provide me warranty service? Even if it is hardware issue? Anyone had personal experience with warranty after unlocking bootloader once?
1. No
2. depends on the country you are in i think

Unlocking the bootloader on Samsung triggers a feature that's built into the phone called Samsung KNOX
Once it detects the change its permanent and will void your warranty

1: If you root your device currently there is no way. So far no one has been able to bypass KNOX.
2: In some countries, local laws force Samsung to provide warranty services to rooted devices as well. But unfortunately this is not the case everywhere.
What about in EU, Poland?
Or in India?
Any idea? Or any personal experience?

I can’t tell you what the situation is in those countries, but I would suggest ask several sources.
I inquired at a local Samsung dealer about the warranty in a country where according the local law Samsung should give minimum 1 year warranty to any device they sell in the country even if the device will be rooted.
Despite this the local representative of Samsung claimed that the warranty is void if someone would root the device.
On a local forum however I read that there was someone who took back a rooted device with some hardware related issue and eventually Samsung had to replace the device because the local law.
Hey @vvvvv5 were you able to find out if you can claim hardware warranty in the countries you mentioned above.
My S22 Ultra is having a minor hardware issue.
