Develop Bugs

Should i check OEM unlocking option in the Developer settings ?

Ok so i have read many posts on XDA about bricked nexus 5x's and many others, sometimes the main probelm is the oem isnt unlocked. I myself have a Nexus 5x that is completely stock no custom recovery no root no nothing, i just update the phone, right now on Nougat 7.0 sep security update.
So my question is, should i check the OEM unlocking in the settings ? i will never install any recovery or root but i think by reading the posts, it seems like its a major problem if this is not checked, should i check it just to be safe ?

If you have issues in your current state they will most likely be hardware related and unfixable via software. But even locked you can completely reinstall the OS via sideloading an OTA or using the TOT method.
Enabling OEM unlock disables Factory Reset Protection (FRP). FRP is a security feature that prevents a stolen device from being activated. There is allot of info about it online if you wish to learn more.
So you need to decide if you want FRP or the ability to flash the factory images.

ok thx dude for the reply, nah i dont care about the FRP. so flashing factory images is easier right ? rather than sideloading or whatever this TOT method is...., and do most mobiles have a oem locked or unlocked ?

Sure, flashing the factory images is probably slightly easier than the other methods. Note that in your case you would need to actually unlock the bootloader to flash the images. With those added steps it's probably faster to sideload.
The Allow OEM unlock toggle has been around since LP I think. An pretty sure it's in phones that shipped with LP. It didn't automagically mean that the phones bootloader can be unlocked though. It should stop disable FRP though.

Yes, most, I think all OEMs leave the possibility to unlock the bootloader.
By default the bootloader is locked on most OEMs (Sony, Samsung, HTC, Motorola, even Nexus devices).
For Nexus devices it's a simple one liner to unlock/lock the bootloader which will also trigger a data wipe but. On Nexus devices it doesn't void your warranty.
For most other OEMs phones you have to follow some steps and usually get some kind of code in order to unlock the bootloader the first time. This will void your warranty!
If you don't know whether or not you should unlock/lock the bootloader, the answer is: NO!
It seems you're not modifying your phones software (Custom Kernel, Custom Rom, Root etc) and you seem to have no intention doing so. So it's not needed and even less "secure" than with locked bootloader. If you do, you should know that you have to unlock the bootloader in order to change the phones software.
Why would you want to unlock the bootloader when the only reason to do so is to modify the software and you do not plan to do this?
On a stock nexus there is no need to unlock the bootloader, you can even reflash your phone with locked bootloader with the stock software image.

yo dude thx for the reply, as i said in my first post, i saw some bricked nexus 5x (they didnt mod anything i think) that couldnt be repaired cause he had the option unchecked about OEM, that is why i was asking for like a safety precaution that if something goes wrong it would be okay cause oem could be unlocked then... what do u say now ? (and yea im not gonna ever mod anything in the phone, learned fom my last phone which i somehow bricked and a man fixed it for for 5$ )

That catch is if if you checked OEM unloking and chose to not perform oem unlock command now.
When something did went wrong afterward, you are able to perform oem unlock but it will wipe your data.
There is no point for doing it.

About xiomi redmi note 5 ai fake rom and fake unlocking problem

I bought a xiomi redmi note 5 ai which contains a fake rom( 9.5.13.0.0 OEIMIFA). In developers option it shows me that my device is unlocked but in fastboot it is actually locked. I tried to unlock it but couldn't get succeed. I also tried xiaomitool, xiaomi flash, some adb and edl proccess but couldn't get any success. In forum I saw test point twice method for whyred but I couldn't active edl by doing this hardware functionality because my device is new and I am also a noob in those matter. My mi id also unauthorised. Is there any chance that I can flash Official China stable rom and get the official update??? I am so disappointed with this. Experts, please help me to flash official rom on note 5 ai. give e some solutions.

Yeah I wanna know about this topic too. Many sellers are sending unsealed products and bootloader saying unlocked.

I'm in this situation too! So sad

This is really weird....In dev options phone says "Unlocked" but when you reboot there is no "Unlocked" sign under Mi logo...WTF?????

You will need to give some more detailed information for people to help you. Go on the guides section, find one of the many bootloader unlock guides and follow it step by step: at which point does it not work, and what kind of error do you get?
You also mention your account not being authorized: if that is the case, then you absolutely need to get it authorized first, there's no way around that (short of finding someone with an authorized account to help you, I guess).
By the way, I would not focus too much on the fact that Developer options report the device as unlocked, if the ROM is unofficial, that is easy to fake. Whoever flashed the u unauthorized ROM must have then relocked the bootloader after flash.

this is why xiaomi has changed the way bootloader unlocks to prevent sellers from doing this.

To my knowledge, the new unlock policy just adds more time before unlock and makes it harder to use the same account for multiple unlocks. I would say it discourages sellers from doing this, but the more resourceful ones will keep doing what they always did, while us users have to endure the whole thing.

I got my redmi note 5 ai, it was already unlocked. can someone point out if it's good? In developer options says unlocked. I turned on usb debugging but OEM unlock is greyed out. Verity mode: true, device unlocked: true and device critical unlocked: true

My first R5+ came with an unlocked bootloader but the unlock process made it for the seller can corrupt eventually some partition or even unsuccesfull, they are not intend to unlock but change a chinese rom for a global and through the process device could get unlocked (time before, I guess not actually).
The most indisputable way without a doubt to know this is simply going to fastboot mode and typing
Code:
fastboot oem device-info
so fastboot reads at a low level directly in the right partition. There are some discussion on where is place this condition, some thinks that is in bootloader itself but others believe that it is in persist partition.

That's what I did. What do you think?

If it is in a greyish, as unmarked so you can touch the toggle but is in positive OEM unlock? then don´t worry about that.
Just look at it before and after to do some update.

Is Mi Unlock really needed to unlock bootloader?

I have searched for a very long time how to unlock the bootloader to this phone. What I came across was the proper way to unlock the bootloader, using Xiaomi's unlocking service. This way tends to take around a week to actually unlock your phone. I am far too impatient for this and have yet to find a better option to get my phone's bootloader unlocked. Is there any better way to do this?

No, you'll have to be patient.

For some reason, mine came unlocked. I bought it from the Xiaomi Ali express store.

I want to buy this phone but am wary because of my past experience with Huawei's locked bootloader, and their requirement to go through them to unlock; which they discontinued right after I bought the damn thing!
This required a payment (about $25 iirc) to a third party in order to get an unlock code.
Is this something I should be worried about with Xiaomi phones?

This shouldn't be a concern for now. Xiaomi isn't planning to restrict unlocking the bootloader. Another thing you should consider is that Redmi note 8 pro gets easily bricked by flashing custom twrp, magisk, etc. but it's not easily recovered as it requires xiaomi authorised account.

You are using the stock rom, right? This is a false alarm. If you can flash modules and edit system files you are rooted for sure.

That's a serious red flag. Make sure you flash every possible firmware from the stocks here...
But if I were you, I'd return it and get it retail properly. Ali Express is notorious for vendors that put spyware and other ****e on their phones prior to shipping.
I got a proper Redmi Note 5 Plus (Vince) once, and retail was supposed to have a locked bootloader in the same fashion as this phone. On Redmi 5, however, there was an even cooler known problem where they would keep people's bootloaders locked, but flash malicious firmware using a testbed by taking the phones apart. So people would receive their Redmi 5's from Ali Express bugged and they would have to wait out those weeks to unlock it and flash clean images.
On an unrelated note, I did use an exploit on that MIUI version by creating two accounts, logging off, signing off, I don't remember. But I unlocked the bootloader the day I got my Vince. I'm not sure if this will work anymore. Not that I needed to. Again, I would never get a phone of Ali Express.

I don't know about spyware but they mainly unlock the bootloader on china variant to flash the global rom and sell it as a global variant. Later the user receives an update notification and installs the update and voala you get your device bricked.

Yes, once in a while they do it just for the sake of putting on a "better" ROM. Some of those Ali Express Note 5's reportedly came with even beta ROMs.
I'm saying just to exercise caution, is all. But a different ROM that would receive the wrong OTA sounds just as bad. I've never even thought about that scenario...

Fortunately, that has not been the case and I've been able to install several updates to the global rom since purchasing.

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.

And that's where I come in.
I sent my Xiaomi Mi 9T Pro as a guarantee having had the precotion of flashing the global rom and re-locking the bootloader (I had a problem with my antenna, I received nothing).
They supported my Mi 9T Pro without any problem

Question T-Mobile 9 pro flashing

Hello all,
So my op6t died a very violent death the other day. I needed a replacement phone immediately so I went to T-Mobile and bought the 9pro outright. Per T-Mobiles guidelines, I have to wait 40 days before they'll SIM unlock the device. Once they do that for me "oem unlock" option should no longer be grayed out and I can unlock bootloader.
My question is, once my BL is unlocked, am I able to flash the global/international version of OOS? Or am I stuck with T-Mobile roms forever?
Thanks,
Pain

You can unlock the Bootloader when you request a token to unlock.
If you paid full price, why not get it directly from OnePlus with no restrictions?

Hey bud, you don't have to wait 40 days, try this, it's reliable, this person already unlocked like 4 different T-Mobile devices for me and there is also a tread on how to convert T-Mobile to EU. Good luck.

That's usually what I do, but I literally destroyed my phone on short notice (caught in the door jam as I closed my car door). I needed a replacement ASAP for work so I just went to T-Mobile.
And I'll definitely check out that thread and send him a PM. Once it's unlocked am I good to flash global OOS releases?

Global is a problem since updates are coming from Google and we can't get a full image.
Better to flash EU in this regard.

Where do we download them from? OP website or oxygen updater app?

I just did this yesterday!
This thread has the instruction you need: https://forum.xda-developers.com/t/...7-to-eu-via-msm-no-unlock-bin-needed.4272837/
So yes, it's possible, but you'd have to keep the bootloader unlocked and flash the T-Mobile modem after every update. Not a big deal.
I actually tried flashing both the EU (firmware ending in BA) and Global full ROM (firmware ending in AA).from OnePlus and didn't notice any difference. But my understanding is that this month is special in that we can download the full update image from OnePlus for the Global/NA variant.

Can you restore those backups with MSM as well?

You can with unlocked BL, just boot to fastboot and flash the partitions. You could use SMT download mode, but I wouldn't advise since it could wipe your IMEI and EFS partition.
