unlock bootloader - Xiaomi Redmi Note 4 Questions & Answers

Is it necessary to get permission from mi to unlock bootloader? Can't we do it our own. I.e. fastboot oem unlock.

Haha. Yep. It's necessary to get unlock perms from them. Otherwise you may fail unlocking OEM with fastboot oem unlock. This ain't nexus or pixel. Lol

Well, most of the OEMs supports unlocking bootloader. That too just like fastboot oem unlock,. For example ; oneplus. But most of those were not like that. We need those OEMs approvals for the same. That's where the Xiaomi is, that sucks.

I think you use that TMO device unlock app.
I thought that was just for carrier unlock, NOT OEM unlock...have you used that app?
thanks

No, I disabled it. Been with TMO too long, I'm not going anywhere and neither are they. Thanks for teaching me the difference, lol! This bootloader is locked.
there are a few different "locks" to deal with on this phone; the bootloader, which is currently locked, carrier lock, meaning you are locked to tmobile, and the OEM unlock, which allows you to flash roms, both stock and custom, assuming you have an unlocked boot-loader
On most other phones, in the developer options, there is a OEM Unlock entry you activate if you plan on flashing anything...

The OEM Unlock option doesn't appear until 7 days after the device was first booted on the Exynos version. That might not be the case with your version because the bootloader is locked so the OEM Unlock toggle is redundant.
Have a read through this thread:
https://forum.xda-developers.com/galaxy-note-8/help/info-note-8-exynos-n950f-fd-oem-unlock-t3673140
I've had many phones with locked bootloaders in the past where the OEM unlock appeared in the dev options, so unless this is something new with the note 8. im not sure why its not there..

All the OEM unlock toggle does is allow you to flash a custom recovery so you can then flash custom ROMs only if the the bootloader is unlocked. If the bootloader is locked like on US snapdragon N8s having the toggle is pointless.
If you check out the thread linked above you'll see that a bunch of people with exynos versions that do have unlocked boot loaders are missing the toggle which later appears & disappears. No one knows why yet, all just speculation.
The N8 is the first to have this happen. What a big headache. Hopefully they figure it out. I'm one of the lucky with an exynos N8 without that issue.
yeah, its not a big deal, especially since there is no way to unlock this bootloader at this point anyways...weird that it comes on and off on the Exynos though..

We already have a root, it just wasn't released yet and it seems to be the same as S8, so with similar disadvantages. Expect to be out any day now.

Even if you get the OEM unlock toggle to appear it doesn't mean anything. If you have a locked bootloader the OEM unlock won't unlock it. OEM unlock is just a safety switch.

Oem needs to be unlocked before u can us cf autoroot or any other means of root I have j7 metro no oem unlock option tried to use Odin and cf auto root it failed because the bootloader is locked and can't be unlocked. I know this is for the n8 but I seem to be suffering from the same problem.

so i cant root or put twrp on my j727U ? SEEN PEOPLE DO IT WITH J727p so why not the U ? no oem toggle on a galaxy how is this, should all come together and never buy phones from a company that goes against what customers want.
so i cant root or put twrp recovery on my galaxy j727U ? ? how has a phone tech not beat this by now even without oem toggle , it should still be beat by now.. this is why i liked htc cause they unlock bootloader for you and allow it on there own page, anyone wanna trade a htc for a new galaxy j7 ?
lol i think this thread needs to be closed
Yes there is an OEM unlock option. I know because I discovered It! Simply flash the K2 combination file, when factory binary loads go into the left hand screen, with apps. Click on the settings icon, then enable dev options the usual way. OEM unlock should be there. You may need to toggle it off and on a few times before you get the popup security message.
It makes a change in the system as it should. If you do a factory reset, then reload the factory binary, you'll see that Dev Options are already enabled (saved from last time you unlocked) AND OEM will already be toggled. This means that the unlock sticks!
So there you go. It even changes the OEM line in the .prop.... that being said...
DO NOT TRY TO FLASH TWRP AFTER DOING THIS!!!
(I already tried, the secure boot still is in effect, and you'll have a softbrick until you can re Odin your recovery. )
The OEM unlock may be one part of this, but there's more. Hopefully we are making progress toward the goal of a bootloader unlock!

Not yet tried, OEM Booloader unlock option is available.
I may lose all security options tied to it. Hence not yet rooted.

Don't bother. He just reffers to 'OEM unlock' in developer options. But that doesn't do anything since we don't have fastboot. So in contrary to the OP, no, it won't 'enable the magic'
There is currently no known way to unlock the bootloader, let alone root the Oppo Find X.

relock with MIUI 10 Global Beta installed?
@smokin901 @AkkiV
-When unlocking, does the hard reset occur? (factory reset, or reset data)
No, unlike unlocking HTC, Motorola ... unlocking occurs without loss of data but if the data on the phone is encrypted, you must first disable the encryption, otherwise the data will be lost. Then unblock and you can turn on encryption again. Exceptions are Mi6, Mi Note 3, Mi Mix 2, Mi Mix 2s. They have a complete discharge. And it looks like this trend applies to all fresh models.

Does this apply after relocking?
It is better to opt for encryption since in Mi devices unlock won't erase my personal data...?

For example Mi 8 Chinese Ver. if you want to relocking bootloader from Chinese Vers. you have to flash Chinese ROM, if you flash Global ROM in Chinese Ver. device, you may brick your device.

You can claim warranty with bootloader unlocked, TWRP installed, rooted and with custom ROM. Water damage will result in no warranty.

AFAIK, warranty for Xiaomi devices remains intact even if you unlock the bootloader.
Obviously you can lick your Bootloader if YOU'RE ON THE STOCK ROM.
You can flash the stock rom with fastboot and select
Clean flash and lock
And your Bootloader will be locked.

Why do you want to lock? It is better to remain unlocked once you have unlocked. In the event of you deciding to flash a custom ROM, you have to unlock again and your data partition will be wiped.

Dirty flash your stock ROM through the Mi Flash Tool. There is an option to lock the bootloader.

Bootloader unlock

I know that the bootloader of most, if not all, Xiaomi smartphones can be unlocked. However, in most cases, this means opening a Xiaomi account and waiting a few weeks to receive a bootloader unlock code, which can only be used by a special Windows app. I prefer to do it in Ubuntu Linux, using the default Google Android way, via a simple ADB unlock, which is possible for my current Xiaomi Android One phone, the Mi A1.
Even if there's currently no custom ROM available, I can tweak the phone by installing some custom configuration files, which is only possible if I can gain root access (not necessarily to "root" the phone for online Android apps).
I am willing to overlook the one major defect of the phone if the phone can be unlocked purely by ADB. So has anybody successfully unlocked the bootloader of the phone? Is the unlock process the same as for the Mi A1, something like "adb unlock bootloader" (not sure about the exact commands as I don't have ADB currently installed)?
This is Xiaomi Android One phone, it doesn't required an Xiaomi account or requesting unlock code...just enable Developer Option, enable OEM unlock and you can unlock the bootloader via adb...

Thanks. I suspect that is the case. I just want to be sure Xiaomi policy hasn't changed, because I read the bootloader of most Nokia Android One phones cannot be unlocked.

No, OTA update engine doesn't check bootloader status . But it will break Safetynet - you'll need to use Magisk or custom kernel to pass the Safetynet.

Question Does greyed out OEM UNLOCK require google play services?

I have had 2 phones both should been able to OEM Unlockable. x0032. I verified that is unlockable. I disable google play stuff. I think maybe the OEM unlock is related to google setup and google is the one OEM unlocking the devices. Any thoughts?
Google services is not related by OEM unlocking in any ways

Then what is? I have two phones that aren't unlocked. One I had for almost a year, CID's are unlockable on the CID list. Tried reset, ect. Something I am doing is disabling it from being unlocked since 100% sure the devices are unlockable.
Has anyone had success unlocking their phone without google services running or doing the intial google setup when resetting phone?
No, you dont need google to do that, They work without google.
Can you give the ss or logs of the error

Then what would explain two phones not being able to OEM unlock?
1.) Cid matches up with list of OEM unlockable phones on both devices
2.) Had internet connection (one for over a year)
3.) Tried every method under the sun listed to unlock it including over 10+ factory resets.
The only thing I didn't do is the setup thing at the start of clean install which is a google setup and contacts google servers.

It is the OEM gray out, not bootloader unlock. Is there a way to log that? Also I appreciate the responsiveness I get on these forums. I will try my best to provide anything possible that obviously isn't personally identifying information.

It is definitely not unlocked. The "OEM_Locked" In the bootloader text is reason I know.

That's the thing, the OEM unlocking is still greyed out on both devices. Both moto devices, both on the list of oem unlocking according to CID. They are not the same devices also. It is really strange.
Then your phone depends on Google Framework and Services,
Then flash into custom ROMs, that would help to unlock bootloader

What are you saying do you know
Flashing rom needs unlocked bootloader and flashing rom does not unlock bootloader

First of all you can't flash a custom rom without unlocked bootloader that I am aware of. Secondly, I am not even at the step of unlocking the bootloader, I am trying to OEM unlock first so I can unlock the bootloader.
Do I have to make a sacrifice to the Motorola gods in exchange for OEM unlocking?
