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.

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
Hi, I have a LG G4 H815 on Lollipop and I want to unlock it's bootloader to root it and flash an update and do other stuff. I want to try to unlock the bootloader the official way but whenever I go into the developer options and press the 'Enable OEM Unlock', it gives me a warning and I tap Ok but the slider still stays at the off position and it stays disabled
I really want to flash some stuff on it because some of the stock LG stuff is pretty crappy. Thanks in advance!
Try to soft reset your device and try after that

I don't have a slider. It's just a tick box. Try updating to the latest version first or reset your phone completely. All your files are wiped anyway when unlocking the bootloader so you have nothing to lose in trying these.

I tried updating my phone to Marshmallow using the LG Flash tool with a kdz but the tool was having its own problems. It kept saying that it couldn't connect to server. I tried a lot of other methods to upgrade to Marshmallow but they didn't work. Do the flash tools need the bootloader to be unlocked too?

Without root or an unlocked bootloader, you can only use official root tools. I don't think your software version matters too much. Just do the full factory reset. There's no reason not to try doing this as bootloader unlocking does a factory reset itself.
I have also tried everything on my lg g4 on marshmallow...but can't turn on the oem unlock tick...
Any solutions
I tried factory reset too but still, not switching :'(

I got the same issue as yours here...and cannot even flash some Stock Rom on this "H815" model.....is your phone a refurbished model from Aliexpress? (as I suspect something here)
Dear all
After spending 3 days searching on the net, I found the way :
"Just purchased a LG G4 (H815). I'm in the process of unlocking the bootloader, and have been following LG's official instructions. However, I am having trouble performing step 8 of this guide:
"Enable OEM unlock on your phone. Activating the "Enable OEM unlock" is necessary for the bootloader unlock. To enable OEM unlock, go to Settings >> Developer options and check Enable OEM unlock."
Going into developer options and tapping on "Enable OEM unlock" returns the pop up message "WARNING: Device protection features will not work on this device while this setting is turned on. CANCEL ENABLE". After checking ENABLE, the pop up goes away, and I can see the checkmark box is checked for less than a second, and then it goes back to being unchecked on its own. Can anyone explain this?
Also, if instead of tapping CANCEL or ENABLE on the pop up, I click off of the pop up, the pop up goes away and the box will stay check marked until I interact with something else. Entering adb reboot bootloader from here though still does nothing sadly.
UPDATE: I had to download LG Bridge, connect my phone and use LG Bridge to search for a software update (H81520H) that my LG G4's update center was not finding for some reason. After the update, I had an update android security patch level, and could enable my OEM Unlock!"
Hi,
Thanks for the reply.
LG Bridge doesn't solve the thing for me, it says "Your phone is up to date" ... I installed and removed LG Bridge a few times and even tried to update it. And even tried the "Update error recovery" (blue text on the bottom right of the window), still with no success.
Still no access to Fastboot for me, even if Adb sees in device when prompting the command "adb devices".
This "H815 20o" software version I got (from stock rom, refurbished phone, with this insane locked bootloader) is driving me nuts for 3 days now...
Up,
If anybody ever got the same issue, any help is very welcome!

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.
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!
Dear friends! I am writing for help. I received this device and ran into a problem. I can't get an OEM item in Developer Options.
I reset the phone to factory settings, then activated the developer mode. This item did not exist. Turned on wifi, checked for updates, rebooted the device. But this point did not appear.
I tried to change the date to earlier, a month, a couple of weeks, a year. It doesn't help. How can I get this item and what conditions must be met? I heard that you need to wait 7 days. Where does the time count come from? Can this be bypassed?
I can’t even install the official firmware through Odin, because it writes about the com port. I changed the device, and on the other device it says a read error. I need to install magic, so this item must be enabled for sure.
Help me please.

Hi there I'm new on this forum but I have the same problem with my samsung s9 SM-G960U the oem unlock option is disabled and cuz the the device is either carrier locked or it have a snapdragon processor in both cases u can't unlock the bootloader cuz the carrier doesn't allow you to flash another firmware same thing with the USA model if your device has a Exynos processor then u can unlock the bootloader (oem unlock) if your device have a snapdragon processor then its a USA model and u can't unlock the bootloader
You can unlock bootloader now. I myself have G965U1, and I did it a few days ago and then installed custom Android 12 ROM.
It is paid service though, contact the author of this thread: https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/
