Stuck on Google Logo, Can't Unlock Bootloader

Hey there.
So I tried to use the Nexus Root Toolkit to sideload the OTA, but now when I try to boot my phone it just shows the white google screen and doesn't do anything. I can use ADB and fastboot and get into the bootloader but I can't flash the factory image because I never checked the "Allow OEM Unlock" tick since I didn't plan on unlocking the bootloader. Can anyone help me out here?

This is exactly why you should never mess with updates or flashing anything with a locked bootloader. If a factory reset doesn't fix it you're likely out of luck.

if your bootloader is locked still I can't see how flashing an OTA would effect this.
Have you tried to flash just the original bootloader from the android version on your device ( not the version you wish to update to )
Fastboot flash bootloader bootloader.img
DON'T USE A TOOL KIT ! UNLESS YOU KNOW WHAT YOU ARE DOING ! There where clear instructions on how to flash OTA's on this site and likely in the toolkit.
Unfortunately this is a case of NOT reading before doing things, I have yet to see anyone recover from this.
Best of luck tho, but it might be a lesson learned the hardway a.k.a RMA

I'll attempt this. Weirdly enough when I look at device info in adb it shows it as being on the newest version. But Yeah I'll attempt to flash what I was on before.
Yeah, I mean I've done this before with no issues on my Nexus 6 and there were no issues but that was unlocked when I got it. I just thought you didn't have to unlock the bootloader to sideload OTA's? I may be wrong.

Yeah like I thought, "Device is locked. Cannot Flash Images"
I wish I had known they added that "Allow OEM Unlock" Switch in Lollipop. Would have solved my problem if I had that toggled.

I bought it used on /r/hardwareswap and whoever I got it from had already unlocked it.

I know someone advised you to try to flash a bootloader, but it isn't going to work of your bootloader is locked. What build were you on and which OTA zip did you try to flash?

I've tied to flash stock, but can't do that due to the bootloader being locked, tried to just hard reset but it just does the same thing where it gets stuck on the Google logo. I checked the manufacture info in the toolkit and everything is clean. Tried to flash the old bootloader but like you said I can't flash since I'm locked. Not really sure what else to do :/

Yeah I think they would do it since I technically didn't void any warrantys or anything. I appreciate the help. What do I need to make sure to do if I do this again in the future? Definitely "Allow OEM Unlock", and do I have to unlock the bootloader? I was under the impression that you didn't have to to flash an OTA.

Definitely unlock the bootloader, it isn't needed to flash an update via the stock recovery, but it is needed to get out of sticky situations like this. If your bootloader was unlocked now you'd be up and running in ten minutes.

Yeah, I'll probably wait for the update over the air for a while and maybe if I feel reallly eager I'll just make sure I unlock and such. Annoying that you can't unlock via fastboot anymore without that toggle. I get that Google is trying to make Android super secure but It's not too useful for folks like us. Sure it's bricked a lot of devices.

I've done it before with other devices. I wouldn't say it's inherently bad. It's just that there was one toggle that I wasn't aware of that caused the issue. You live and you learn.

THIS IS NOT MY IDEA !
I found this in a N9 thread and it worked according to the user with the issue, apply this with the correct t factory image ( do it with the version you have on your device not the one you tried to update to ! )
This might not work but its worth a try ! Before doing this read about ADB and Fastboot !!!!!!!!!!!!!!!! Try and understand the basics and know what the commands are doing to help backtrack e.C.t
If it does work - go to settings and allow OEM Unlock and USB debug !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Then go read from reputable sources how to flash images manually via adb !!!!!!!!!!!!!!!!!!!!!!!
I'd follow vomers guides.
Had this problem with another device cool thing to remeber is that on locked devices the only thing that is different is that there is a signature before the MAGIC header so the solution is to pull the android stock images from https://developers.google.com/android/nexus/images. Once done extract the images in both the zip and the tar that is inside the zip. You will see recovery.img inside the tar. One thing about the boot process of TWRP is that it enables adb in preboot meaning while in the boot loop you should have access to adb. With access to adb all you need to do is dd the images over the corresponding partitions: i.e.
PLEASE NOTE NOT FOR THE FEINT OF HEART. I AM NOT RESPONSIBLE FOR YOU BRICKING YOUR DEVICE.
Quote:
adb push recovery.img recovery.img
adb shell dd if=recovery.img of=/dev/block/<recoverymmcblock>
I dont know if the default recovery has adb push update so id probably recommend doing this on every partition thats inside the tar, i.e. system, boot.

[How to] flash Global to China Mi6 without UBL

I bought the MI6 and find out that without tools or unlock bootloader, there is no way to flash a global rom to china rom. My Mimax convenient EDL cannot be used in Mi6.
Unlock is easy, but since mine is new and under warranty, i prefer a Xiaomi rom.
Luckily i fond this tool:
https://drive.google.com/uc?export=download&id=0BwypTnSm1wlhTkp0ai1LUXZKdkk
Credit to the dev http://en.miui.com/forum.php?mod=viewthread&tid=663972&highlight=xiaomitool
Download this, run, and follow the screen.
it will check your boot, recovery, then list the rom that possible to install.
Choose global, lets it download, choose recovery and the tool do the rest.

Thank you. I will give it a try on " bricked" mi5 and new mi6.

This tool make unlock bootloader automatically... so your warranty is gone after

It is not working locked bootloader

Just ask for permission to unlock bootloader, usually takes a week or so. Unlock > flash > lock again. No need to experiment with some tools or whatnot official.

I already had been using the phone for long enough, the permission took 4 hours to go through. Never been an active user of their services either.

Actually I am looking for a way to wipe whole partition as my second-hand mi6 is binding with a mi account which is not mine.
Flashing in EDL mode is easy to flash any official from you want but asking to unlock the device after setting up.
Though there is some tricks can be done to bypass the checking, I cannot log on my mi account or even restart device.
I had just had a tried as this thread: https://forum.xda-developers.com/mi-max/how-to/installing-twrp-locked-bootloader-t3406501
To flash TWRP directly by MiFlash. But fail to boot in it with a 'the system has been corrupted'.
Just wanna give more ways to flash or unlock with the limitation of officially unlock BL

Bypass lock code?

So I sold this phone on swappa fully functional and the buyer managed to get some kind of lock code on the device and returned it. Anyway how do I fix this since I can't even get to settings or anything without this code? It's not a FRP, it boots to the lockscreen but when you unlock instead of going home it goes to this screen where it asks for a code. What do I do?

Does it show how many digits it's asking for? Is it sprint variant or open market?

I kind of do think it is asking for a netowork unlock code most likely. However, I don't really know how to bypass it because I can't get to the settings to enable USB debugging or anything.

I would suggest trying the Back to Stock zips on it because it wipes everything and see if that works. You can also try and load TWRP and use it to delete the lock screen password files and then flash the boot image so it boots normally and then you should be able to swipe to dismiss the lock screen. Hope this helps you out

I believe in fastboot mode you don't need usb debugging. In fastboot is where the network unlocking happens.

I can't wait to get my hands on the device.
Think you can unlock the bootloader with fastboot/adb (same as with Nexus/Pixel/Oneplus-devices) no?

Hey!
After enabling OEM Unlock in the developer options, the commands to unlock it are:
fastboot flashing unlock
fastboot flashing unlock_critical
Hope this helps.

What about relocking?

same commands, just change "unlock" with "lock" ^^.

I like old OnePlus brand/Carl Pei for that, Root Friendly
No Knox, No 169 hours Waiting Period or Forbidden Unloack Bootloader.

It's premature to say whether this will be possible or not, as the Phone(1) was released only 5 days ago.
But knowing Carl, I think that everything will be allowed on this smartphone so that it can be used by many people.
It will be a while before we have a custom recovery and therefore can develop around the Phone(1).
But the kernel is already available for developers which is a good sign.

Is it able to retain L1 status after unlock?

After unlocking (without root, unmodified partitions):
I still have L1 wildvine ("DRM Info").

You need to install Magisk (and also root your device) in order to install Universal safetynet fix module and ofc actually pass safetynet. Worked fine on my device.

If you have read my tuto with all the process and explanations , you would have seen this point that concerns your question:
12-Once you’re on the bootloader menu, you’ll now have to switch to using fastboot command to communicate with your device. To unlock the Nothing Phone 1’s bootloader, enter the following command: fastboot flashing unlock
In case you need to flash low-level firmware partitions like the bootloader images, you will have to execute another command afterwards: fastboot flashing unlock_critical
