ok so i just bought my v20 yesterday and i tried to root it, i did the adb and fastboot method and it seems like everything went fine but when the phone booted back up it shows the lg logo then it goes to the at&t logo and its stuck there, what should i do? did i brick my phone or what? or does it just take a long time for the twrp recovery to boot?

Does ADB detect the device
Sent from my LG-H910 using Tapatalk
First boot usually takes about 20 minutes on Sprint variant, not sure if it's the same for AT&T.
At&t requires an extra step from the opp I got stuck there too but if ADB detects the device you can flash a working boot .img in twrp by typing adb reboot recovery which is easier than fastboot. Here is the step just in case

It has come to my attention that some users have encountered abnormally long first boot time(over 20 minutes before first time setup)
To resolve this issue:
Boot into bootloader by pulling the battery and reinserting it and holding VOL- and phugging in the phone. then typing:
Code:
fastboot flash boot bootbackup.img
fastboot reboot

I try to reboot into recovery with fastboot, trying to flash another recovery but it stucks on logo fastboot

problem solved.
If you would enter in recovery with latest firefly 3194, push volume down and shutdown buttons.
At the begin it seems phone stucks on boot logo oppo find but wait some minutes without press buttons and it automatically enters in cwm recovery.
Then at reboot, it stucks on that chinese words, to overcame them, I pressed shutdown button with volume down for some seconds, or only shutdown button and then starts.

I've tried every possible way to enter in recovery, and what i've just to do was only to wait more or less 100 sec. However it's strange why phone doesn't enter in recovery via fastboot. When i put commands on cmd, it continues stuck on fastboot mod despite cmd says "rebooting"
I guess i need to hold from flashing firefly

Yeah, got in same situation after firefly OTA update(prev. chinese version), though I got a brick LOL
This was introduced by the 2013.05.09 update(OTA or full ROM) and the trick is indeed to wait a bit more on that screen message, maybe a fellow from China help us understand what it says in that message.
The message u got is put by Oppo to overwrite the custom recovery image with the stock one.

I recovered from bricking my phone, but a new problem popped up: when I reboot my phone, it boots into the Bootloader screen. I have to manually start.
How do I make the phone boot normally?
Details:
Rooted
Went to stock, re-rooted phone, reinstalled TWRP
Nandroid restored to last good save.
Running rooted Stock February 2016 update.
Anyone? It really is annoying: it always reboots to the screen with the green bot has it's gut panel open. I am not telling it to reboot into the bootloader screen.

The current state of my tablet is quite curious: Its stuck on Google logo and it will be this way until the battery completely drains.
What I've tried:
- Holding the Power button shuts it down for 1 second...then it boots right back up by itself.
- Recovery (POWER+VOL DOWN) doesnt work, it goes straight to Google screen.
- Connecting via USB to the computer, Windows doesnt recognize the device.
In fact, the only way I found to Turn the Tablet off is popping the back cover and unplugging the battery cable. I've left it unplugged at night, hoping it would clear some sort of Cache, didnt work. Also I've tried unplugging the battery cable, plugging it back and Turning it on with POWER+VOL DOWN in hopes of acessing recovery but it goes straight to Google screen.
Additional Info:
- This happened while I was trying to downgrade from 5.1 to 4.4.4.
- My device is the LTE version of N7 2012
- My device is currently rooted.
@RavenEffect hold down the power button for at least 20 seconds to turn it off, 1 second is not enough
How did you try to downgrade? Probably flashing went wrong? In worst cases the bootloader was erased during downgrade ... in that case ther will be no hope.

1 second is the ammount of time the tablet remains off, not the ammount of time i've pressed it. Yes, I've held it 20 seconds obviously.

Followed this guide right here: https://drive.google.com/file/d/0Bz6x7k-VkpUJU09paVM5cmh2Xzg/view
All the steps worked until the fastboot flash boot .\boot.img command. Sometimes it would get stuck on the command prompt and the tablet was frozen in Recovery Mode. I had to close the command Prompt, reboot the tablet into recovery again and Flashing another thing first, like recovery and system and THEN i would flash the boot.img.
So theres no hope?

Yeah, of course, but there is one problem. I can't boot into recovery mode, the bootloader got destroyed. So the only thing I have is either google logo with padlock on the bottom or nothing with APX mode. So no ADB, no FASTBOOT.

I know for mediatek, there is smartphoneflashtool, which flashes to the device when it's turned off. I don't know if there is an equivalent that you can use.
I don't think NRT does it, so you might be screwed.
There is nvflash ... but only if you have backed up *your* individual device images before you need them. So if your device is already bricked there is no chance ...

Problem is that, when you plug the Tablet to the PC via USB, it doesnt recognize the device, like I've stated on the original post, so I cant even get to a step where I can flash any sort of file.
Well, if I think about it, only the bootloader got destroyed. The image is free on google sites. I just have to put the bootloader image into the tablet so I can get to the bootloader and flash everything else with fastboot. There has to be way to do that. I mean if the "BIOS" (screen with google logo) got destroyed, that is bad, but it is just matter of damage on free to share universal loader. There has to be way...
Hopefully someone can help me out here. I have been trying to root my phone, and everything goes fine but for some odd reason as soon as I relock the bootloader the phone wont boot anymore, I just get stuck at the boot screen indefinitely and have to revert to stock. I went through this process several times with the same issue, and unfortunately I got frustrated and started messing around. Not thinking I went into developer options and uncheck "allow OEM unlock," and forgot about it and rebooted. Now I can't get the phone to boot, but I can't flash unlock either. It will not boot into TWRP for some unknown reason as well, so at this point I don't see how I am going to fix this.
Even better, I just got the phone today...

Do not try to lock the BL if you are not completely stock.
If you have TWRP or anything like Magisk installed do not lock the BL.
If something goes wrong, you have a brick.
only lock the BL if you are completely stock.

Man, I could have sworn it was not recommended to leave the bootloader unlocked. Not exactly the answer I wanted to hear unfortunately. Any idea why it won't boot just because I relocked the bootloader? It just seems like an odd thing to cause a boot loop, and it did it 3 separate times

try reinstalling TWRP and flash LOS again, I think once you flash a different software the OEM UNLOCKING switch are not highlighted anymore(what I mean is you can't turn it off), if you can do fastboot, try doing fastboot -w and wait till it reboots.

Check any forum of a phone with an unlockable bootloader. You never ever relock the bootloader unless you are 100% completely stock. Once relocked with modified software there is nothing you can do to get it to boot.
Your only hope might be a deep flash cable and qpst if you can figure out how to use it.

Yeah it just continues to boot as normal, and then of course goes into the boot loop.
I cannot reflash twrp or any other room. Attempting to flash anything fails with the error cannot flash while locked. Same with using -w
Did you try the fastboot unlock command?
