14 day wait for bootloader unlock?

Is this possible to skip? Can we unlock with adb / fastboot or is that not going to work / likely to brick the device?

Unlock Resposibly
adb or fastboot unlock will only work after 14 days of waiting. It is to allow you to rethink your decision. OEM unlock will obviously void your warranty and applications like Android pay will stop working. Trust me, relocking will not be easy as unlocking. Even if you somehow get it relocked, Android pay will still not work for you. So, unlock responsibly.

Thanks for the reply . I'm really doing it for root access, modifying the hosts file, changing fonts and boot animation, but the latter two aren't necessities.
I don't use Android pay (don't use contactless) but I am a little concerned that online banking will cease to function when the phone is on a stock firmware and rooted. If there's an effective system wide ad blocker I may use that instead.

For hosts file, I recommend dns66, available through fdroid, no root required.

i have found that many banking apps will continue to work with root provided you also have a hide root app installed but android pay is a no go.

Thanks! First I've heard of fdroid, looks very useful, and dns66 does exactly what I was planning on doing.

CHEERS

Hello guys.
For those having bootloader unlock server issue (normally everybody), there's a post on the Lenovo forum that gives the origin of the issue:
https://forums.lenovo.com/t5/P2-P2a...-bootloader/m-p/4574568/highlight/true#M12457
In fact, the problem seems coming from an non renewed SSL Certificate in the Lenevo server tracking the OEM Unlocking requests.
The suggestion given by fls2 is to change the date of the P2 phone to a previous date than the 10 July 2019 and the Bootloader Unlocking process should be launched.
That's what I've done with a second P2 I bought that has its bootloader locked.
I set the date to 10th of April 2019 and the phone is now waiting for 14 complete days to engage the OEM Bootloader unlock instead of the usual Lenovo ID error pop-up.
I'll wait for the process to end and see if everything went fine, but it seems that it should be OK as it was with my first P2 phone.
I'll keep you informed if there are some trouble in the process but I stay confident.
In case of success, we should address a very big "thank you" to fls2 for pointing out the issue with Lenovo server.

20 days have passed since registered. Always shows error.
Unable to unlock OEM.
Don't know what to do...

Hello everyone,
As I have written in my last post, I've used the suggested method of manually changing the date to one before the 10th July 2019.
So, as I've said, the 14 days counter has been correctly launched and I was able to see the counter evolving from 14 to 2 days.
Then I was a little bit busy and I haven't followed my P2 phone until last week-end.
When I tried to consult the status of the bootloader unlocking request, I had the same annoying pop-up telling me there's a problem with my account.
The date was fixed to 10th of April 2019 manually, but still had connection error pop-up.
I then tried to switch to current day date of the week-end (29/02/2020), and tried to check again the bootloader unlock status: Annoying pop-up again.
Before giving up, I've tried putting another date manually but at least 14 days after the one I've put when I made my first request and still before the 10th of July 2019, so I switched to 10th of June 2019.
This time, when I checked the bootloader unlock request, I've got no error and had a positive bootloader unlock message that told me the phone is going to reboot and erase all user data that are present.
The phone has rebooted in Fastboot mode and I was able to send the awaited "fastboot oem unlock" command from my laptop.
I didn't try to reboot the system and see if the fastboot command will work if I go in fastboot mode by myself, because I didn't want to miss the opportunity to succeed in unlocking the bootloader of this phone.
I let the people brave enough to try if they feel comfortable with that.
Now this phone is working with an AICP Android Q ROM that seems very stable.

Try to follow my steps.
There's no reason I've succeded and you cannot.
I'm sure you'll be able to unlock your bootloader as I've done.
If you have some question, just feel free to ask.

I'm trying to unlock the bootloader too. Is there any way to avoi waiting 15 days? I'm still using the Stock Rom by default (Android 6).
According to the last comment in the Lenovo forum, the changing date no longer works.
Thanks

AFAIK, no. You need to wait that. Also there is bigger problem than that which its the unlocking bootloader (server problem). Just you can read above, for no reason you cannot unlock bootloader.

@mahmutpekkara somehow I managed to unlock the OEM. It took me few attempts tho, so I'm guessing their servers are not always operating. No needed to change the date in my case.
Only 3 days remaining, so hopefully everything goes well.

So, after 15 days waiting I was getting the message ''Server sync data success'. I managed to get thru by signing off and signing in again with another account. Flashed properly and enjoying Syberia OS

7.1.2 FRP Problem

Hello guys!
I have next problem:
My sister had factory reset her device, and she forgot her google account, which were used for this smartphone.
Now, when we try to start the phone with different account, we are facing FRP, and we can't use the phone.​
As it appeared USD Debbuging and Bootloader are locked. Firmware: 7.1.2 (N2G47Z, Jul 2017)
May someone guide me how to start this device?
Thank you in advance!

There is no way to bypass or remove FRP. Your best bet is to contact your carrier.

I did remove FRP from 5X August security patch, I can try to help you... Do you have telegram, so that we can chat?

That's wrong!, I did remove FRP on my 7.1.2 through the help of these guys https://www.facebook.com/giaiphapandroid
They connected to my pc via teamspeak and you connect your phone to it. They use Lg flashing software I belive to completely reset the phone to stock. Had to pay 20 US dollars, I was very skeptical at first but heard they were legit.

is possible to bypass that, i did it few days ago
this is the easiest way if you have the 32gb version

I need help. I can't unlock my bootload，Who has an unofficial method？

I tried every possible way to unlock my mi6, but they all failed, including the international version, the Chinese version, I want to use the third-party rom and root, but I can't unlock my device so that I can't brush in recovery, I tried to force brush in recovery, but my mi 6 can't start, so I want to ask if there is any unofficial way to help me solve the problem of unlocking bootload, please don't tell me to use the official tools, because I tried. Who has an unofficial way to help me, thank you

AFAIK there's no unofficial bootloader unlock for the Mi 6 now.
You might get one eventually but it is unlikely since even though the three days waiting sucks it does work...
What was not working on the unlock?
Did you bind the account on your phone and then wait three days (minimum) and then use the unlock tool (latest version)?
If not then try again.
Give us more information and we can help you.

All I have tried, before this, I have a mi5, I think I should know how to unlock, it should not be my problem, unlock tool tips I did not bind, but I was bound state, I tried Kind of version fails, the same problem, my account already has permission, I think there are unofficial mys5 bootload method, I think mi6 may also exist, so I come to ask you a solution? In fact, there is a region in our country can be solved by mail bootload but need to pay, I do not want to pay do not want to mail. So to ask

First. flash the Chinese development rom,
and then unlock

At which point you failed?
1. Failed on 99% unlock tool?
2. Failed to get the system unlock on Developer Options (the error appear as toast and say something like "10008 参数错误 请参考API文档") ?
If it's #2, then you must connect to any VPN server that is located in Mainland China (Beijing/Shanghai).
If it's #1, then you most likely have to wait 72 hours after you receive your unlock permission from your SMS.
I've just unlocked Mi Mix 2 2 weeks ago. The difference I noticed from when I unlocked my Mi6 is that I need to connect to VPN server in China. Half a year ago, I don't need to do that.

Thanks for your help, I have unlocked successfully. Will you compile the rom? I have encountered some problems.

Root/Oreo - new device

Good day all,
I'm going to be in receipt of a Global Mi Mix 2 shortly and would like to ask what the best method of unlocking/rooting the device is?
I see some comments around going to Oreo update first?
I had a Mi5 in the past and the best way to do this was via official means --> Request unlock code --> Receive code via text --> Use official app to unlock phone --> Now flash TWRP via fastboot etc..
Is this still the same with this device or can you unlock the bootloader unofficially?

Same way as the mi5 but you will need to link the phone to account via settings first. To do this you will need to access a Chinese VPN via a play store app.

Can you recommend a VPN? I've tried several - most don't have a Chinese server, and every one I've tried that does gives me a "Connect to the network and try again" popup.
I've had my code and the app and everything ready to go for quite some time, but I've never gotten past the China barrier.
I *really* want to get rid of these "buy things in our app store" ads they've started serving up in the latest update....

Many of the Global Mi Mix 2 come unlocked, so you may not need that

Please HELP to unlock BootLoader - nothing works, looking for unofficial method

Hello there,
I've searched through all the googles and i can't seem to be able to unlock my mi 5S
Bought a half dead phone, glitchy screen and bad battery. Purchased new parts and had them installed.
Phone came with unlocked BL and lineage OS, but i f-ed it up by flashing a miui rom that locked the BL.
Then I found out the phone was actually bound to an existing MI account, so I cannot unlock it with the official tool.
Phone is in edl mode, i tried searching for an unlocked emmc_appsboot.mbn but no luck.
Can anyone please advise how to unofficialy unlock the bootloader?
I'm about to sell it for parts as I've been trying to fix it for the past week ... :crying:

Not sure if there is a way, because that way could also be used for a stolen device...
My suggestion is that you contact your seller and ask him for his Xiaomi account or that he deletes the phone from his account.
Weird thing though, the phone does not get locked if you just flash an official ROM. You specifically have to choose "flash + lock" in the official flashing application to have it locked again.

I've been emailing with xiaomi support, gave them all the details. Maybe I can convince them to remove the account.
Before flashing i was checking online on how to do it with miflash tool but i missed the radio buttons and default was clean and lock ..

After a few documents submitted through [email protected] they have removed the unknown mi account.
To conclude, I have not found any way of unlocking the bootloader except for the official way.
Also, be careful when flashing with miflash, don't lock your phone by mistake.

Ah great that it worked!
