I have a stock 2012 Nexus 7 Wifi + 3G which (was) on 4.4.4. The power button does not work in the bootloader or when booted up, but I can use it to reset the phone and boot into the bootloader.
I had the bright idea of using the Wugs Toolkit to reflash the factory ROM to see if that would correct the problem. Unfortunately, the bootloader was still locked.... it formatted the partitions but then couldn't write anything back, so now it will only boot into the bootloader. I can't unlock the bootloader because you have to confirm you want to unlock it by pressing the power button, which doesn't work.
Is there any way I can unlock the bootloader without having to do that power button press to confirm it?
Thanks
Ian
it is getting flashed every time I unlock or lock the bootloader. Below are the steps I took to lock and unlock.
1) Enabling the developer options.
2) Enabling OEM unlocking and USB debugging.
3) Entered the fast boot mode and used "fastboot oem unlock" command to unlock the device after this command the phone gets unlocked but it erases(factory reset) all the data of the phone.
I was trying to install the magisk manager.

Looks like you haven't been on xda for the last month or two, or didn't do a little research before unlocking bootloader.
After May Security update, unlocking process factory resets the phone. You need to hold down volume down buton before executing oem lock command. Search on xda for proper instructions.

How "lock" or "relock" my samsung SM-T510 bootloader?
im getting annoyed by the message when it boots
I would like to know how to do this as well after flashing stock firmware in Odin, the option to toggle off OEM unlocking is grayed out. Any help would be awesome!

You can't choose the OEM lock until you re-lock the bootloader. You do that the same way you unlocked it. But be warned, it does a factory reset also, which means you have to go through the whole setup proceedure again. BTW, it is unlocking the bootloader that causes the message, not the OEM lock. Also, do you know that you don't have to wait for that message to disappear on it own. If you tap the power button when it appears, it goes away without the delay.

The OEM lock is grayed out. I have factory reset everything. Through Odin and device. I just want the bootloader locked again and reversing this procedure does not work. Not worried about erasing the device I've already downloaded the 2 to 3 hour 2.3GB file I pushed through Odin

Did you actually read my post. OEM and bootloader locks are two entirely different things. When you first unlocked your tablet, there were two steps involved. FIRST, you had to enable developer mode and turn on OEM enable. THEN, you had to unlock the bootloader by holding the proper buttons when powering up. To relock, you have to do that in reverse. First relock the bootloader,using the same buttons you did to unlock, and then, and only then, you can disable OEM. And the second step is optional. You don't have to disable OEM to get rid of the message.
Edit: And "reversing the procedure" does work if you do it right. It is the ONLY way to relock the bootloader and I have done it. So I know it works.
reedit: OK, I just did it again on my T510. Turn the tablet off. Plug the cable into the PC but NOT the tablet. Hold both the vol up and down buttons and then plugin the cable from the PC. When the green screen appears, release the buttons and then press and hold the vol up till the next screen appears. IT WORKS!

No I do NOT mean download/fastboot mode. Go back and research how to UNLOCK the bootloader. IT DOES NOT USE FASTBOOT. You DO NOT use fastboot to unlock Samsung devices. And "factory reset" via Odin is meaningless. You don't use Odin to unlock the bootloader either. BTW, Samsung and most other reputable tablet makers, intentionally make it hard to unlock their devices because it is a serious security risk if you don't know what you are doing. Do you know what you are doing?

I actually do know what I am doing as a matter of fact. I rooted all of our devices in this household including friends and family. Some of them are in my signature. You don't have to be a dbag about someone asking for help. Yes, I read your posts too, even after all your edits. I got it finally so I guess thanks for all of your generous replies to point me in the right direction. Have a nice day!

I apologise for getting snappy but I was starting to get frustrated trying to point out that the OEM lock wasn't the problem and that the "buttons" did work.
Thanks Lewmur
Just wanted to pop on and say thanks lewmur, I was getting sick of not being able to update and singe I bought a Galaxy S9+ I cant root that, might as well keep them both stock and use "altered" apk install files. I was not sure if it was possible to relock the bootloader, now I know lol, so thanks.
I have a TAB S6 running Android 10. Bootloader is unlocked and OEM switch IS NOT grayed out. I went into DL mode and all I saw was the same thing as when I unlocked the TAB in the first place. Anything special I need to do to re-lock this baby.

...Like you said, your instructions do work! But i think folk are getting confused in your last sentence...
..."When the green screen appears, release the buttons and then press and hold the vol up till the next screen appears. IT WORKS!"
with the term " 'hold' the vol up" you use - instead of 'Long Press' the middle Volume button option on the screen!
This method by Long Pressing Volume Up button will get you to the three options screen which asks if you want to lock your Tab...

This works for SM-T870 as well FOLLOW BOLD TEXT of above, just did it. Stupid easy THANK YOU SO MUCH LewMur
Hello,
I have a unbranded 8227L running 8.1. In the past I have been able to successfully unlock the bootloader, but now I can't figure out how to get past the warning message. I check the box for oem unlock
in dev settings, then while temp root in place I reboot into bootloader. Then I run fastboot oem unlock, which presents me with the warning that my data will be wiped and to hit volume up to accept. For my life,
I can't remember how to get past this. I only have a volume knob, not a button to push.
Anyone have any ideas?
