I wish. At&t has the bootloader locked down. All the other steps will probably work. Twrp would have to be built for M255. Thanks for the response.

So, you don't have "allow device to be OEM unlocked" option in developer options?

I do. Tried enabling, but still trying to get a grip on it.
Update: still can't enter fastboot mode. It just reboots like normal.

Can't I run the oem unlock command while in download mode?

Not as of yet. Sorry.

Hey all, just got this phone, I had originally "done some research" when I was at the att store, and found root instructions for the lg k20 PLUS (missed that plus part). So I bought the phone and now im finding out there's currently no root method, which means, as usual, I have to at least try. I warn you, I'm no fulltime dev, so don't get too excited, im the kind of guy that still needs plenty of help with this stuff, but I'm setting up a dev environment and digging in.
My question right now is, has anyone been able to access the bootloader? I read thru the k20plus root topic a bit and they say to use
#adb reboot bootloader#
or hold VOLDOWN and plug usb while powered off.
Nothing seems to bring me to a bootloader.
#adb reboot bootloader#
reboots the device and I assume it tries to boot the bootloader and fails, because windows chirps as if it's been disconnected, then my device proceeds to boot up normally.
Holding VOLDOWN and plugging the usb makes the phone show a splash screen momentarily and then switch to the powered off charging screen.
Has anybody been able to access the bootloader?
-BMFC

Still waiting here too. ??

What u mean with "bootloader" are fastboot.
To get into download-mode hold Vol+ & plug-in usb
Fastboot may for u arivable but u have to wipe ur recovery partition first.
Then reboot into recovery...but wait !
It's look like freeze..plug-in usb and hit on ur PC "fastboot device"
Welcome !

there are two different versions of the gpad tablet. If you didn't buy it through the Google Play Store it is not the GPE.
I am not aware that adb can be used with the bootloader on the regular LG g pad.
the second thread in the general section has information on rooting your lg device.
if you did buy it through the Play Store then make that the first thread.
might I ask what you're trying to do? There may be another way.
ah gpe google play edition of course! i am trying to put a custom reocvery onto it. using a script i found online and it doesn't seem to be working.

also, if you are using Linux you may follow the first post in my signature below for the fluxbox blog. In there is a complete guide to root your pad from start to finish using Linux as your base.
the second step is to unlock the bootloader. how do i accomplish this?

are you using Windows or Linux?
you first need to download and install ADB properly on your computer. Then make sure that your device is read by your computer, and then proceed from there. Again, if you are using Linux feel free to follow my signature below if you are using Windows however you will need to definitely follow the guide in general.
right now im on windows. the guide in general is what this post was about. when i type the command adb bootloader reboot to get into the bootloader it just reboots the tablet. is there a way to manual do this?

There is. From a device that is off, plug in your USB cord and then press the power button and the down volume button at the same time. The bootloader screen should come up. I don't know that this works for a locked bootloader.
When you type in "adb devices", you should receive a prompt on your tablet instructing you do accept your computer as an interface. I recommend trying this first. Without adb you stand a good chance of messing up your device.
im not getting a dialog box on the tablet but adb does see the tablet

don't watch video's, rather take a good guide here from XDA ! learn adb/fastboot commands and use them wise......if you don't know what you are doing stop it and read up first and full understand what you want to do.

ADB reboot bootloader

1. Flash TWRP
2. Flash SuperSU ZIP
3. Done
Unticking the "Fast boot" option was a bit unnecessary even before.
Unticking it just prevented folks from getting confused why they couldn't get into bootloader from a "Power off" condition (which with "Fast boot" is really not a true power off, but a deep sleep mode).
If you used any other method, like selecting "Restart" after holding the power button (which is a true reboot) or holding down the Power + Vol up to reboot; those always worked to enter bootloader (by pressing vol down while rebooting).
For all the guides that said to untick "Fast boot" I always just left it on, since I preferred it that way.

In the last update (lollipop) the fast boot option is disabled. So all you can do is backup your stuff and factory reset your phone so it will go back to the previous update where fast boot option is available.

This information is false, for more reason that one (see below). If you bothered to read a thread, I already explained it above in Post #9.
1) The only thing the "fast boot" power option (in Settings) prevented, was going to bootloader from a "power off" condition, as in this case, the phone isn't truly powered off (just a deep sleep state). But you can still get to booloader with a REBOOT, which is always a true reboot; even with "fast boot" power setting enabled.
2) With the "fast boot" power option gone, Item 1 above is irrelevant. The absence of this option in fact makes it easier to get to bootloader, not harder. This is not related to the Android fastboot/adb interface, if that is part of the confusion (as the name is practically the same).
3) Your advice about doing a factory reset is false, as a factory reset does not return you to a former OS version (despite somewhat popular misconception). All factory reset does, is delete user data. Plus, what you advise is completely unnecessary due to Item 2 above. Users on LP or MM are free to get into bootloader, unlock bootloader via HTCDev.com and root; without returning to any older OS version (which is actually impossible without root and/or s-off).

[SamSung Note 4 - SM-N910A] HardBrick - QHSUSB_BULK help

OEM battery was replaced with new batteries bought off amazon. After the new update, suddenly it started randomly rebooting on me. and next thing it knew, if would show me a Samsung Logo screen and be stuck on it.
I saw some suggestion and I did the remove battery and held the power button and down vol. it reboots.. and every it auto restart and goes to the downloading screen... i just remove the batter and restart the process.
I accidentally on my reboot select the boot from bootloader, and from there it Hardbrick. It no longer turns on, as good as dead, but when I plugged into the PC... I hear 3 beeps... and QHSUSB_BULK driver not found.
I bought a jig, and see if it would help me go into the Bootup Mode, but it was still unresponsive
I was hoping if anyone is able to offer me some guidance
we are able to unbrick it
......if we had someone to help use with the development by just spending the extra few minutes on helping us
What kind of help do you need?
I saw post about Jtag service saying that they cab fix it, should I give them a try?
I have a device that did the same exact thing. Started acted funny, then just hardbricked on a battery pull. Same error message on computer when plugged in, despite locating correct drivers, etc. I am really upset because I've lost a lot of pictures and videos of my little girl. I wrote to a jtag repair person & they felt jtag would not help. And of course I've done all the usual stuff, new battery, all the button combos, etc. It's deader that a door nail, no charging light, vibrations, nothing. I've not dropped it, gotten it wet, nothing.....it just died. And a few few days short of my upgrade, too! Go figure. Anyhow, if ANYONE can PLEASE offer any help, that would be awesome. Even if just as much for me to recover my pics from the emc.

If you were not on full stock rom without root, or anything custom, and you turned off OEM unlocking and USB debugging, then locked the bootloader, you are basically hosed my friend
Look at this point it just needs to be said... PEOPLE STOP RE-LOCKING THE DARN BOOTLOADER!!
PERIOD!!
There are literally a half dozen posts this week with probably bricked phones and a good amount of them are this same root cause.

My friend.....you could give me or anybody else 10 thousand bucks, and it's still not going to solve your problem I'm sorry to say. You should have unrooted the phone first, then fastbooted the factory image, or do a factory reset, and made sure that OEM unlocking & USB debugging were left on until you were done locking the bootloader. Sorry man, but there's not much you can do without at least a stock recovery, so....accept the loss, learn from your mistake, and move on. Many of us here, including myself, have been there as well.

Pixel 2xl Can't Find Valid Operating System.

I've tried to lock the bootloader. But after locking the bootloader the phone restarts and shows the message that Can't Find Valid Operating System.
In FastBoot Mode it shows:
Secure Boot -Yes
Device State - Locked
My Bootloader Version - TMZ20k
Baseband Version - g8998-00253-1809191716
What's the solution?
Hope you didn't try to lock the bootloader without being fully stock...
If so, you've just bricked your phone.
If you're fully stock, you can bootloader unlock the phone again and start over.

does your computer recognize your phone?
if so make sure you have up to date adb/fastboot
boot into bootloader then open command prompt
type fastboot flashing_unlock
why did you relock your bootloader?
maybe try deuce's script or the all in one tool. They're pretty handy

Yes My Computer recognize my phone.
After entering this command "fastboot flashing unlock"
It Shows:
FAILED (remote: 'Flashing Unlock is not allowed')
Have you tried adb sideloading an ota file?
If that doesn't work I'm not sure what else you can do.

I've tried to lock the bootloader. But after locking the bootloader the phone restarts and shows the message that Can't Find Valid Operating System.
In FastBoot Mode it shows:
Secure Boot -Yes
Device State - Locked
My Bootloader Version - TMZ20k
Baseband Version - g8998-00253-1809191716
What's the solution?

By chance did you turn off OEM unlocking and USB debugging before you locked the bootloader? If so, it's......Brickhouse time! :fingers-crossed:

Yes unfortunately I've turned off OEM unlocking and USB debugging before locking the bootloader.
Isn't there any kind of solution???:crying:
If you're under warranty you can return it.

You could try sideloading the OTA through stock recovery like @Edmontonchef suggested. I don't think it'll work, but at this point, anything is worth a try.
Could somebody PLEASE sticky a warning on every section to NOT RELOCK BOOTLOADER?? Pretty please??

While that would be nice my friend, I also think that there is enough information out there already that if users were willing to search for it, they would find out quickly that this is a no no. Unless of course, it's done in the correct manner. :fingers-crossed:
Why did you relock the bootloader? What advantage did you expect to gain from that?

You mean, put THAT sticky right next to the sticky that states, SEARCH FIRST, or the one that states "generic questions belong in the Q&A section for each device"?

Or next to the sticky that states "generic questions belong in the Q&A section for each device"?
Or any of the other 100s of stickies that the vast majority never read?
Those stickies?
I'm actually AMAZED at the "right now, immediate gratification" mentality of so many people nowadays.
I have this $800+ device, I want to customize it, what should I do first?
1) read the OPs and research the guides for my device PRIOR to messing with it,
or
2) skip all the research and OPs and flash my new device the way I flashed my Note 3 from five years ago?
Who in their ever loving right mind picks 2??????

I feel bad for new members like the OP. No doubt this will be a learning moment for him, and he seems sharp enough that I think he'll be okay down the road and will do the research needed before customizing his devices.
The members who have been with Xda for years and STILL don't research, read OPs, read stickies.... those are the folks who chap my hide

Yeah, don't let it get ya down Hoss! Some folks just like learning things the hard way I reckon. We both did. And, in the long run, they'll be better off for it :good:
