Try this, had the same problem yesterday:
If you get stuck in a bootloop rebooting the tablet after unlocking the bootloader...
Here's what you do..
1) During the bootloop.. hold the power button + volume up + volume down button simultaneously to get yourself back into fastboot mode as you were previously.
2) In fastboot mode.. use the volume keys to scroll to Recovery and the power button to select it.
3) In Recovery (Android robot on his back with a red triangle)... tap the volume up button and the power button simultaneously which will bring you into stock recovery. Again.. Don't hold the buttons, just tap them simultaneously. Also make sure you're holding the correct volume button. Up will be the volume key on the right.
4) Once you're in Recovery.. perform a factory reset/data wipe and then reboot your tablet... you should now be back to the Welcome Screen.
The guide is from "Cyber Warrior" over on AndroidCentral, google "[How-to] Unlock/Re-lock the Google Nexus 10 Bootloader (Mac/PC)" (can't post links yet), in the 2nd post

Exactly what I did to solve the bootloop after unlock. Worked with no problems after factory reset/data wipe. Just went back to the 4.2.1 I had on it.

With my Nexus 7, when unlocking the bootloader, it would automatically factory reset itself. The Nexus 10 doesn't appear to do this, but it does appear to be a required step regardless (I guess unlocking the bootloader does something that is only fixable with factory reset, for security reasons).
So as mentioned already, a factory reset should take care of things

thanks for the tip.i got something like that，i unlocked rooted the tablet and all was ok untill i went into system settings to update it via ota. after the ota had been downloaded succesfully it rebooted into recovery automatically but failed to update. then i couldnt get into the system any longer even after i flashed factory image using the toolkit in another thread.
i will try this when i get home，hope it can solve my problem too.
edit：done. thanks again for the tip

rebooting into TWRP help

Quick question for all. Have TWRP installed, rooted all good.
Trying to reboot into recovery when power is off. I read to hold down vol down and power until LG pops up then let it go then hold it again.
I do that, then the bootloader screen pops up. What do I do, I'm lost!!

ONLY USE THIS METHOD IF YOU HAVE TWRP INSTALLED!!!!! OTHERWISE YOU WILL FACTORY RESET YOUR DEVICE!!!!!
While the device is powered off, press and hold Vol - and Power button. When you see the LG logo quickly release only the power button and re-press and hold the power button (Never let go of the Vol - button) This will boot you into the LG Factory reset screen. ONLY USE THIS METHOD IF YOU HAVE TWRP INSTALLED!!!!! OTHERWISE YOU WILL FACTORY RESET YOUR DEVICE!!!!! Choose yes to both options and you will be rebooted into TWRP. TWRP intercepts this command and ignores the factory reset part.

There's a nice app in the Playstore by the same guy that makes 3minit battery called 3minit rebooter. Free and works awesome to reboot recovery.
https://play.google.com/store/apps/details?id=three.minit.Rebooter

or, use adb on your computer and do "adb reboot recovery" - it is the most reliable method for me

The same method helped me get into recovery. Just remember to let go of the power button for around a sec before repressing it again.

Hardware button don't work in bootloader?

Hey guys. I just got LG G6 H870 model. Unlocked bootloader without much problems, but issues came later. While being in bootloader I can't do anything, hardware buttons seem to not work. The only way to get out of bootloader is to use "fastboot reboot" command, but that prevents me from getting into custom recovery after flashing it. Only entering download mode works (holding volume up and plugin in usb cable). Non other key combination work until I boot into system.
Can this issue be somehow resolved?

I had similar problem myself with entering recovery more and the reason behind it was that I didn't press the button combo in proper way. what you actually have to do is while you in fastboot mode you press down and hold power button and volume down button. phone reboots after a moment and you should still be holding these keys and when lg logo appears you let go of power button for brief second and then press it back again and then when a prompt on white screen appears just go yes two times and phone shall boot in recovery mode . I had watch a tutorial movie to figure that out. other easy way is just to have adb enabled and reboot it with adb reboot recovery command via USB cable

No, because I had G5 and I know the proper way to do that. Problem is I can hold the power button as long as I live and the phone won't reboot, regardless of pressed combination or power button solo.

and the adb command way ?

Well... Nevermind, turns out vol down button isn't working at all.

still good way around is adb reboot recovery

Recovery and Download mode

Hi all
I am not able to boot into recovery mode or download mode. I am fully aware of 3 button combinations to boot into recovery or download. Has anything changed? How do I get into download mode?
The other thing is whenever I restart my device after unlocking the device it say device is restarting for 2 seconds. Is that normal?
S10+ Exynos model unlocked
Edit: The phone not booting into recovery is solved but still I cannot get into download mode directly. I have to go to into recovery then boot to bootloader.

Just a question how did you unlock the phone?

Phone is factory unlocked. By unlocking I mean unlocking the device after a restart(inserting a pin)
Maybe restoring data from Samsung cloud leads to this problem. I had the similar issue on my older galaxy device

To get into Download mode on the S10s - do the same thing we had to do on the Note 9.
Make sure ODIN is Open on your PC and the Phone is off and not plugged into USB Cord yet.
then hold power, vol down and bixby and while holding those three buttons, plug in USB Cord to phone - it will boot into download mode - press vol up and you are ready to use Odin.
If you want to go to recovery - with phone on- press down vol down, bixby and power until screen goes black - keep holding power and bixby and move the other finger to volume up - hold until it boots into Recovery
Hope that helps -

Can't unlock bootloader

Hi,
I have trouble unlocking my A40. It's 2nd piece I own and the problem is the same.
When I follow the steps from this forum;
Go to Developer Settings and enable "OEM Unlock" option
Power off the device and boot in download mode
In download mode, you will see the long press and volume up option to unlock the bootloader
Unlock the bootloader. That will wipe your device so be sure you made a backup of your data
After bootloader unlock, boot up the phone and make sure it is connected to the internet or it will trigger rmm prenormal
Setup the phone without google account and others
Reboot in download mode and flash the recovery and vbmeta images
Boot to TWRP
Format data in TWRP
Flash the Multidisabler zip
Now you can reboot

I'm stuck at the 3rd point.
I don't see ANY instruction about Volume UP + Power in download mode. Nor FASTBOOT see my device to run actions with it.
What I see is only "Volume down key + power key for more than 7 secs Cancel (restart phone).
And holding Vol UP + Power doesn't do anything.
How to make this work?
Thanks.

You did enable OEM Unlock, correct?
Turn the device completely off, without any cables connected. Keep a USB cable ready that's plugged into your PC.
With the device powered off, hold both Volume buttons, and plug in the USB cable connected to your PC. Do not press Power. You should see a prompt on either a green or blue screen; select the option for Device Unlock Mode.

Finally.
Thank you for making me try for another time
