my phone (US996) stuck in Logo LG. But before I was in the red triangle because i try to back to stock and I thought that i flash the firmware US996k keeping root would work well, but not this just lock OEM. But now the OEM has been blocked and I can no longer enter recovery. What can i do?
-The LGUP detect the phone but with unknow model. I put the dll in common and doesnt work. I dont know how to unbrick my phone
-I think the OEM is blocked, because I tried the "fastboot oem lock" command and it says it was already blocked, then try to unlock it "fastboot oem unlock" and says: FAILED (remote: unknown command). I think it's because the box was unchecked in Settings> General> Development, but the problem is that I can not boot to activate it.
Use LG Bridge. It has a button to recover from a bad flash. You more than likely will have a locked bootloader, and not be able to root again, but at least you will have a working phone.
Hi i try what u say i get bad news.
When I give error recovery.
It analyzes the phone but in the end it just tells me there are no update errors that can be recovered. And there it ends and does nothing
Have you tried using Uppercut to see if LG UP will recognize your phone?
Yes i try, and recognize but always like unknows model, i can´t continue. I extract dll from KDZ but not work.

Before I describe my issue I'll let you know I've been looking up articles on how to solve this for weeks now. first post to XDA, so bear with me I'm new
I have two OPT, both have a similar problem, but one is working (I dare not try to mess with it) and the other I've already tried and tried and now I'm stuck in fastboot, no recovery, no OS.
I HAD an OS on it (Paranoid Android 6.0.1), but I couldn't factory reset, and I needed to, so that I could sell the phone. when I tried to factory reset through OS settings, it would boot loop until I hard reset the phone. I had no recovery apparently (IDK how I did that) but trying to install a recovery requires the "OEM Unlocking" setting to be checked. and for some reason it won't let me check the box. My working OPT phone has the same problem, the "Allow OEM unlocking?" box pops up, I select enable, and the toggle moves itself back to the grayed out selection. so I couldn't install a custom recovery, I can't do any formatting or erasing in fastboot either without that selection for some reason either. trying to only gives me a "FAILED (remote: device is locked. cannot erase images)" or "FAILED (remote: device is locked. cannot flash images)"
AND SO, I tried this (search google for "mega unbrick guide for a hard bricked oneplus 2". I can't post links apparently as it is my first post. it will be on the oneplus website) and now I have no OS. or at least I believe I have no OS because trying boot causes a bootloop. I've tried all the methods, but I'm assuming because my bootloader is locked, It failed with the "A2001_save_brick_mini" tool.
And so, all I have right now is bootloader. didn't have a recovery I guess, and now I think I don't have an OS. and I can't do anything in fastboot because is returns with a "FAILED" hehe. dang locked bootloader. I have no idea how both of these phones have locked bootloaders anyways, because I obviously unlocked the bootloader to install a custom ROM in the first place. did the bootloader relock itself, or maybe during the process of installing the ROM, the bootloader relocked? I'm not sure as I wasn't watching for that. the phones had booted with the new OS, and so I happily went along my business and didn't find out I had a problem until I tried to factory reset one of them.
no I have no phones now with similar problems, but at different stages of the same issue.
My ONE A2005 is working, but I can't toggle the "OEM unlocking". At least it has a working custom recovery (TWRP)
and MY ONE A2003 is stuck in fastboot (fastboot recognizes it via "fastboot devices" and I can reboot and "fastboot oem device-info") with what I believe to be no recovery or OS.
ask me any questions to further explain my predicament, and PLEASE offer me any things to try. I ave two phones to test different things with. I would prefer to keep the working one working though.
Have you tried the fastboot oem unlock command?

Ah yes, I forgot to write that in. That also results in a "FAILED (remote: unlock device to use this command)"
I can't unlock because of the OS, or perhaps lack of OS now; And I can't install a new OS or recovery because my bootloader is locked
use qualcomm recovery tool if you can't get any help. it'll restore your phone to 100% stock
Hi I've seen threads around that have the same issue is there any help I can get.
I only have access to fastboot
my device will hang on LG logo
I've tried flashing recovery and it won't boot into it
I also tried https://forum.xda-developers.com/showpost.php?p=70393155&postcount=3 and cannot flash misc, fota, but I can flash cache
- the error i get here is " remote: cannot erase this partition in unlocked state "
-- so i locked it with fastboot oem lock and fastboot flash lock and i get the same error with it declaring a " locked state " forcing me to unlock the bootloader again
I've attempted to flash .kdz files with no luck as im in download mode and the guides even say to put in download mode and LGMobile support tool isn't able to detect phone saying it's not even plugged in.
- is there a .dll file or something i need I've read twice in two different post maybe it's typos
I ran LGMobile support tool and it fails after downloading the .kdz file (my guess) not being able to put the phone in download mode is causing it to do so
I'm running out of ideas can anyone help?

Im stuck in LG LOGO and i can´t access to recovery.
Hi All,
Trying to flash an A1 with the following rom images and both give the error of Mismatching image and device.
tissot_images_V9.5.9.0.ODHMIFA_20180316.0000.00_8.0_f8cd1b4e8e
tissot_images_V9.5.11.0.ODHMIFA_20180504.0000.00_8.0_1a04581058
The phone is currently a brick belonging to a friend of mine, and I would like to try and get it back up and running. Fastboot can see the device, as can MiFlash, but when running the command
Code:
Fastboot oem device-info
it throws an error stating
Code:
FAILED (Command write failed (Unknown Error))
Any ideas? The device will boot into fastboot but no further, and gives a warning about being unlocked when you try to boot. I'm not sure how to check if it is a re-branded Mi5x or not, as the box is a Global version A1 box with corresponding IMEI cods to a model MDG2. The phone does have the Android One laser etch on the back however.
By bricked I mean the phone will turn on, load the warning about an unlocked bootloader and then go to the Android One "bars" screen you see before the pretty android one loading screen. Here it just stops.
The drivers i'm using come from the MiFlash install, and I've tried doing a TWRP install with fastboot but still no joy. Fastboot can see the device, and talk with it, but nothing I seem to do has got the kit back working.
Anyone able to give some help or advice?
Further info on what ive tried here
http://en.miui.com/thread-3158263-1-1.html
So I'm stupid and I wiped everything fully intending to install other software but my phone ran out of battery. Now there's nothing but fastboot. I tried to flash the twrp image onto the recovery part but it says FAILED (remote: unknown command) for everything I try. Any advice? I know the bootloader is unlocked because it says it's unlocked everytime I "fastboot oem unlock".
Hello. I have a lg v20 H990N. I flashed TWRP by dirty santa method and wanted to go back to stock. As per the instructions on the link https://forum.xda-developers.com/v20...-h990-t3624296, I used method 1a for going back to stock. I ran the code as mentioned in the method while using my backed up "abootbackup.img" but I accidently ran the code twice.
Code:
dd if=abootbackup.img of=/dev/block/bootdevice/by-name/aboot
sync
sleep 30
sync
After booting to bootloader. this is what I see written on the boot loader screen.

3) Check boiotloader is unlocked
Fastboot getvar unlocked
*How to exit fastboot mide
USe "Fastboot reboot' command if fastboot is available
________________________________________
This is the meassage that pops up in fastboot. I can use fastboot but can't use "fastboot flash recovery twrp-3.0.2-1-h990.img" as it exits with error that remote: device is locked. I can't flash kdz with lg Up as Lg up says " there is no haadset connected". TWRP recovery is also not boot neither is the nougat rom that was installed. More \over my device is shown as "Kedacom USB device " in device manager in fastboot mode. Not in Com ports.
It apperas that my bootloader has locked somehow after flashing abootbackup and I can't unlock it as h990N is not supported by LG to unlock bootloader. screenshot attached.
Please help!!!
Yeah flashing the stock bootloader relocks most v20 variants, (the dirty santa bootloader can't truely unlock them, it just ignores the lock)
I'm not sure what you expected? Your link is broken, but it sounds like you reflashed stock firmware and then the stock bootloader and expected to be in a different situation than a fresh unrooted device?
You should be able to boot normally to Android or boot I to download mode and reroot from scratch.
