Relocking the bootloader after vendor build change - General Questions and Answers

So, I have the MIUI 12 EEA on a Mi 10 Lite, and it's not the stock ROM but the Vodafone build (QJIEUVF).
As there's the new Android 11 update coming, I'd like to have that and not wait for Vodafone to release its build, as that's notoriously slow.
I tried the official Updater app, to install the XM build, but it says the network carrier is different. Seems like the only way is to unlock the bootloader. However, it seems that means losing Netflix and Google Pay support?
Now, can I unlock the bootloader, flash the QJIEUXM with XiaoMiToolV2, and then relock the bootloader with Clean and Lock? Would that lead to a softbrick? Any other downside to doing that, such as losing OTA updates?
I tried to find info, but it's really hard to find any reliable information anywhere

Hi, I am on the same situation as you, did you successfully relocked your phone?

[Q] New to the Android world, i have afew questions for your

I'm totally new to the Android world and i spent many hours to read this forum to learn as much as possible about my device and what i can do with it. But now, i need your help on a few things.
KitKat vs Lollipop, does it make sense to upgrade to Lollipop now or should i wait? Is there any major know bugs?
Since that i only have a 8gb device, i would like to clean the apps as much as possible. There's many apps that i don't need but they can't be uninstalled. For example, all the Motorola apps (is there something that we really need from them?), a few google apps like Google+, Google Play Films, Hangouts, etc that i will never use.
I want a stable ROM that i don't need to patch every day to solves problems. When i read about CM12 for Moto G, i see people that have problems here and there and wait for the next daily build to give it a try. I don't want to play that game!
If i install a custom rom, i guest that future updates will not come from Motorola. How the updates work afterward?
It's ok if i must have my device rooted
I have read about stock lollipop optimized version by lost101 but it don't think that the versions currently available will work for me. I'm in Canada and the versions that i see is Brazil or Asia.
thank you for you help!
You have the xt1032? Is there any warranty left? If there is no warranty, I recommend unlocking the bootloader before doing anything. It is easier to restore a bricked phone if you have an unlocked bootloader.
If you intend to stay on stock, you need some of the Motorola apps in order to install OTA updates.
Well what I will say is. I'm in the uk using lost101s BR optimized and I'm very pleased with it.

The phone is new but i don't care about the warranty. I've read that i can unlock the bootloader with the Motorola tutorial. I must be honest, i'm a little bit lost. I don't fully understand the difference between "unlocking bootloader" and "phone rooted"!
and yes the model i have is XT1032

You must unlock boot loader first then flash a custom recovery (manually or there is a tool in the development section) then rooting next.
Unlocking the bootloader allows you to install non-Motorola software. With a locked bootloader, the only software that can be loaded on your phone would have to be digitally signed by Motorola.
Rooting gives you administrative access to the system files.
You may not need an unlocked bootloader to get root and you do not need root to unlock a bootloader.

I tried to install TWRP (any version available) but it take like 1 minutes to show the home screen and im not able to "swipe to unlock". So i have installed Philz recovery and then installed lost101 Retail Brazil 5.0.2 Stock ROM (Optimized) v1.1a. I'm playing with it right now and so far so good.

[S8+] Purchased a stock AT&T S8+ in a lot. It has latest bootloader and bad IMEI....
First off, I'm an engineering scientist with years of development experience developing both hardware and software for all sorts of phones and companies. So I feel I'm pretty familiar with Android and every conceivable (and off-the-wall) way to get this phone unlocked, rooted, and/or just flat out usable. And I have failed which is why I am finally giving this to the multiverse in hopes there is someone with some solution I have yet to attempt.
I have been searching and trying every possible option for a week and counting. I'm also aware of how close to impossible it is to work with locked Snapdragon CPUs. But not entirely impossible. There has to be a way of reviving this phone!
So I recently purchased a lot full of untested and "for parts" electronics. In there was an AT&T S8+ with a cracked screen. It was also stuck in a boot loop, so I can safely hazard a guess that someone tried to update the ROM, bricked it, and didn't realize they could reflash stock firmware and fix it. Well, upon further examination, I discovered they had attempted flashing a V7 bootloader. Yes, version 7. So that basically robbed me of any options I may have had, as well as all the bugs I could have used to root the device. All I could do was install Pie with a V7 bootloader. Voila! The phone boots up. But it gets better....
Now that the phone was working, I did some examining, one part of which was the IMEI as I wanted to unlock it if possible. I check the IMEI, and it is frakking blacklisted! So that blew ever being able to use this phone on a network. I even sat on hold for 46 minutes to speak with someone at AT&T to see if they could remove it off the blacklist. They promptly said "sure!", then transferred me to someone else to fix it and the guy said "no".. So it's stuck locked to AT&T, which sucks because I checked with several other networks who all said the phone could be used on their networks. But that's not an option if it is carrier locked and impossible to unlock. :silly:
Furthermore, OEM Unlock is 110% unavailable, and no bugs work or exist to force it to appear on Android 9 Pie like you can with 8 Oreo and 7 Nougat; and I tried for days. So the bootloader is permanently locked. If it wasn't, I could root the phone, fix the IMEI, unlock it, and get the phone functional again. Alas, I cannot, at least any time soon, if ever.
I've tried every possible thing out there to root this, unlock the bootloader, and/or try to roll back Pie to Oreo, Nougat, or some stock ROM with bugs that are still active. At the very least just to change the IMEI and get the phone working again. But there is no version of Oreo/Nougat that can be installed with a V7 bootloader.
Also, there is absolutely no Engineering Mode (NOT Developer Mode) available under this stock Android 9 Pie, either by code or by app/settings. Does anybody know of an exact Android 9 Pie stock ROM with an accessible no-root Engineering Mode?
And I've tried every way out there to force OEM Unlock to appear, but the bugs that work in Oreo and Nougat have all been patched and none of them work on Android 9 Pie. So I'm stuck with this ROM and bootloader
So I'm here today with these issues in hopes someone may have solutions for:
A way to force OEM Unlock to appear under Android 9 Pie (as no Oreo/Nougat hacks work under Pie)
A way to bypass KG state under stock Android 9 Pie (as no Oreo/Nougat hacks work under Pie)
A way to install Android 8 Oreo or Android 7 Nougat with a V7 bootloader
A stock ROM with Engineering Mode available
A way to change the IMEI without root
A way to modify the V7 stock ROM so it installs a Nougat/Oreo ROM instead of Pie
Another option to keep this phone from just being a fancy, pretty paperweight
Any solution we or I may discover, I will clean it up and make a guide to help others with these same issues as there is not much info yet V7 on bootloaders. So this is a group activity that could help many, many people; help me help us all!
Thank you all in advance for anything you can offer to help!

EDIT 1: I forgot to mention that the KG State is stuck on "Checking...." so I couldn't get "OEM Unlock" even by waiting
I used this video to figure out how to get the OEM Unlock option.

Hopefully this helps.

There is no OEM unlock on us snap dragon devices. Locked boot loader. Closest you will get is the combination firmware. But the OEM unlock in that does not work trust me on this. The imei is cert coded to the hardware. And can't be discussed on xda how to change. It's possible. But not by just anyone. The combination files are nougat. But their not going to help you out in this situation

Question: Unlocking while firmware updates?

when unlocking the bootloader and there is a waiting period of 1-2 weeks but in the meanwhile the phone wants to update it's firmware, what to do?
- is the unlock process interrupted when the phone updates itself to the next miui version?
- or is it actually necessary to update to the new version to successfully finish the unlocking process? (f.i. the "unlock" process started with the old miui version but ends with a new miui version)
the community blog is not clear about that, anyone got experience with that?
EDIT: nevermind, already done. for those who want to know nevertheless: don't update the firmware while on a waiting period to unlock, just stick to the version you started unlocking the phone, it works. though, it might work with updating too I've not tested it.

Question Updating while waiting for bootloader

Hello is updating phone while waiting for bootloader time will reset it?

No will not. Only removing account will or adding again it again and again.
But if ypu plan custom roms why to update? I had newest miui there was 12.5.1 or something higher but it was ****. Just go to custom.

Thank you

Huawei P30 GSI / Project Treble possible?

Hi,
After almost 2 years of owning this awesome device, not even once i stumbled upon any rom or root solution for it. Now after all that time being desperate for any development on this device, I come here for an opinion, answer or any idea how to get anything written above on this device.
So, I read some things about GSI roms being able to work on any device without porting and all that. I immediately downloaded the app called Treble Check and it said P30 is supported. So it got me thinking, in THEORY if somehow i got mine P30s bootloader unlocked, or if someone unlocked it before Huawei stopped unlocking bootloader, IS IT POSSIBLE TO GET GSI ROM WORKING, AND HOW?
If it is, is there any, even shady source to get the bootloader unlocked?
Bonus question if all this isn't possible: How to get EMUI 12 Beta Project in Serbia thru Beta app? Carrier locked model. ELE-L29.
Thanks.
I actually tried it, but stopped using it due to problems such as FOD coordinates and Volte.
Also, if you install GSI, your PC will not be able to recognize your device.
The boot loader was unlocked using DC Phoenix and hcu-client.
