I did something stupid while trying to restore my phone... I forgot to Enable OEM Unlock before I flashed some boot images and now the phone constantly boots into the boot unloader screen with only two options: Restart or Power Off.
Is there a way to flash firmware on my LG V35 from fastboot?
Edit:
So far I was able to get it into 9008 mode and flashed the abl_a, abl_b, laf_a, laf_b, boot_a, and boot_b files that I had backed up before unlocking and rooting my device.
It seems no matter which img files I have on the device it will forever just boot up into fastboot mode.
Edit2:
It appears most of my problems are because I didn't enable usb debugging and didn't enable OEM Unlock... Not sure what to do from here or who to contact
So far I was able to get it into 9008 mode and flashed another abl_a and abl_b and boot_a and boot_b that I know works, but it still keeps booting into fastboot mode and won't let me turn the phone on.
Yeah I know I'm the only one who posted and commented. Story of my life. Always talkin' to myself.
Anyway. Found a guy I highly recommend that helped me fix my phone remotely.
You can find him on facebook here.
He's in Vietnam, so be aware of time difference. He only asked $20. I gave him $35 because I was so happy with his help.

First, let me say this because i've used xda for a while and i know im going to get these responses:
I know this wont reinstate my warranty...
Why? Because I want to. I understand you think it's useless but it's not your phone...
I have tried "fastboot oem lock" and it doesnt work...
I've searched Motorola's site, got on a chat with them which was useless, and searched xda...
So I booted into AP fastboot and connected to my computer. Opened CMD and typed "fastboot oem lock begin"
That seemed to start the process so then ran RSD lite (as admin) and flashed a signed xml of 4.1.2
Yes, I edited the XML first and removed the 2 lines with "getvar" in them
RSD finished and the phone rebooted (which was great because before it was hung up on the unlocked bootloader warning)
Unfortunately after turning the phone off and then back on, the unlocked bootloader warning screen still came up.
And after booting back into AP fastboot it still said UNLOCKED.
did i miss a step?
I need to relock the phone. if anyone has useful information it would be extremely helpful. in the event it just cant be done thats fine. but i feel like it can, because after fastboot oem lock begin the command prompted told me that now i can flashed the signed images.
well crap. i may have just answered my own question. do i have to flash manually through CMD (ie fastboot flash system system.img) AND THEN run fastboot oem lock at the bottom? i'll try it tomorrow.
before i started this the phone was stuck on the bootloader warning screen so if anyone is stuck at that point this will allow you to boot up your phone. and if my results are typical, it did not relock the bootloader (obviously). hope I helped someone. hope someone can help me. thanks.
most likely not feasible
unlocking razr m involves phisically blowing a q-fuse, so you can't go back to locked
even if you could, it would be traced forever that you've unlocked the BL
You can relock the boot loader on the Dev edition, but once unlocked you can never go back to original status 0 of the boot loader and the boot logo will always display the warning even if you relock the boot loader. You have to flash that partition with another logo image to avoid that.
You also need to wipe the user data partition in fastboot first for the fastboot oem lock begin command to complete successfully.
Once that is done, when it reboots you will see that in fastboot it will display status 2 locked instead of status 3 unlocked.
This is a physical change that happens to the hardware when you unlock the boot loader an efuse on the board is blown and that memory location is permanently programmed. Its not even a question of them knowing, even though they do of course, the device itself is altered.

Help! "Your device is corrupt. It can't be trusted and may not work properly." (Red)
Hello,
just recently i rooted my Nexus 6p device and unlocked the bootloader, i noticed however, after rooting the device i received an error on boot up stating "Your device software can't be checked for corruption. Please lock the bootloader." (Orange), but after researching on the internet many people said that was normal due to the boot loader being unlocked...
however my concern for today is i have flashed back to the factory images of marshmallow, and am now experiencing an error on boot up that Your device is corrupt. It can't be trusted and may not work properly." i followed the exact step-by-step guide on how to unroot and lock the boot loader on the link below however am still experiencing the issue, please help it will be ever so much appreciated.

I've had that as well with mine before. The way I fixed mine was a somewhat tedious process but it did work for me. Start by downloading one of the angler images from Google, then with 7zip, decompress the .tgz which gives you a .tar. Once more will get you a folder named xxxxxx-angler. (I think it was that way but not 100% sure since I'm not at my laptop at the moment). With your phone (unlocked) in bootloader/fastboot mode, run flash-all.bat. this gets you back to a fully stock system but still has the corruption flag tripped. Run stock recovery and do a factory reset and the corruption warning should be gone and back to the "normal" screen saying please lock the bootloader.

Try doing this process manually, if you're selling it. I would infer the data doesn't matter on the device.
Depending on which OS you are on. Focus your command prompt with fast boot installed to your directory containing the stock files (unzip the image zip)
Now do the following process manually. Step by step
fastboot flash bootloader bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash vendor vendor.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot format cache
fastboot flash cache cache.img
Now, if you still get the red warning. Repeat the process and add :
fastboot format userdata
DO NOT FLASH THE USERDATA IMAGE
If this does not work, I have other suggestions.
same prob in orange..plz help bro

To flash back to stock, you have to boot into bootloader and using fastboot to flash factory image.
But hey, you're in the Nexus 6P forum, try following this guide in the Nexus 5X forum:
https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
I just went through this. Just unlock your bootloader with the Nexus toolkit and it'll go away that's all i did

It happened to me just last week. Just unlock your bootloader with the Nexus toolkit and it'll go away. That's all i did and it went away i got it the same way you did and that's all I did

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?

this does not work for me! after it says writing boot.... it fails.
alright so your still in fastboot right?
Doesnt work for me. Say
writing 'boot'...
FAILED (remote: device is locked. Cannot flash images)
Im stuck in LG LOGO and i can´t access to recovery.
So, I bricked it. All I have is fastboot. It thinks it's locked after I messed with twrp. Partition table is gone, I think, flashing another one is declined due to locked bootloader. The device is unrecognizable in lmsr, thus unable to flash. Deep flash seems to be the only option, but how do I get to there? I'm new with this phone, just 2 days old now. Is possible to open the device up
EDIT: the trick is fastboot oem blankflash
