US996 stuck in fastboot - LG V20 Questions & Answers

I was using LineageOS (latest official build). I was trying to flash an updated bluetooth modem image, and the boot screen said my image was corrupt.
I was able to use LGUP to reinstall US99610f. Now I'm stuck at the fastboot screen on very boot, even after removing the battery. The phone is locked again, and I can't flash the unlock key through fastboot.
Code:
target reported max download size of 536870912 bytes
sending 'unlock' (1 KB)...
OKAY [ 0.026s]
writing 'unlock'...
(bootloader) Error!!
(bootloader) Bootloader Unlock key write fail
FAILED (remote failure)
finished. total time: 0.068s
I'm unsure where to go from here, I've tried:
LGUP again
Hard power down/reboot
LG Mobile Flash Tool (CSE mode?), but that failed
Thanks,
Doug

I used LG's Web Chat Support, told them what happened. They were very accommodating and sent me a prepaid shipping label. They classified it as an "In Warranty - Software Failure", fixed it and shipped it back to me.
They did this even though they knew it was bootloader unlocked. Took about 2.5 weeks total to get it back.

us 996 fixed
i had a h910 flashed over to us996 that was stuck in fastboot. i had tried everything from flashing all the us996 firmwares to frp reset and came up with nothing. i then flashed H91510c_00_VTR_CA_OP_1007.kdz it not only successfully flashed but got me out of fastboot mode. i am now reflashing the us996 10f and will re root and twrp .. hope this helps someone out.

[HELP] Soft-brick, cannot unlock bootloader

With what seems to be a soft-brick Google Nexus 7 2012 Wi-fi model, I tried going through comminus' tutorial on both my laptop and my desktop, but I end up with the following error message when I try to unlock the bootloader, an essential part to fixing my boot loop/soft-brick problem. I am unrooted, by the way, so TWRP and other custom recoveries are not an option unless there is a way to flash them via fastboot. I cannot access ADB in any way whatsoever.
Code:

I have verified that both computers can detect my device correctly via the fastboot devices command.
I do not understand what is wrong with my device at this point. Any pointers or tips would be greatly appreciated.
Bump. I could use some help regarding this issue, preferably before I have to depart for Los Angeles on the 2nd!

Have you tried Wug's Toolkit? I have been here myself, checked the softbricked option and even had to flash back as far as 4.4.2. Place your device in fastboot and check the soft brick option let me know where you get with this suggestion.
I just wanted to let you know that the first thing I noticed is the following error:
FAILED (remote: Bootloader is locked.)
This has to be unlocked first before you will be able to flash the OTA. You can use wuget tool to unlock the bootloader and then try to use fastboot. Once that is done, you can relock it if you want.

That was one of the first things I tried, actually, on suggestion of some friends who have experience with the device. Sadly, none of the driver options worked nor did the softbrick option get me anywhere, so I moved onto doing it manually doing it via cmd instead.

I am fully aware that I need to unlock the bootloader before doing anything. I wanted to see if the so called flash all script was going to help AFTER seeing that the unlock bootloader command did not work whatsoever as you can see in the first block of code in my post.

I tried doing everything, not rebooting to recovery either. If i try to restore stock factory images it says device:locked. When I try to unlock bootloader it says failed. I am going nuts from the past 4 hours trying to fix this. Please someone help me out. I have a feeling my EMMC got damaged or corrupted. And I followed the steps to the last letter. Also I am not such a noob that I will do stupid steps or forget performing a single step. Please help me out. I am not able to reboot into recovery using fastboot either.

Hi, I'm getting that as well, I think it's because I got the february update OTA, which changed partitions. Now I just skip flashing gpt bin and go with the rest. It flashes fine and then I install the OTA February update.

If you have root with systemless flashing boot.img, then wifi will not work, you need flash original boot and you will not be root, actual solution for rooting, is for europe roms.

XT1575 Stuck in bootloop

My phone was working great (rooted), and just this morning it freezed.
I hard rest it, and it reloaded to system and then freezed again after a short time.
Tried to re load it and it was stuck for more than 15 min in the boot animation.
Tried to get into TWRP, it showed the TWRP image but then rebooted.
Re flash TWRP 3.0.2, tried to enter into it but again rebooted.
Reinstalled the phone using
http://forum.xda-developers.com/moto-x-style/development/pure-firmware-tuff-wip-t3224833
with "Moto X Pure 3rd Gen (2015) XT1575 MPH24.49-18-3.zip" (using all the fastboot other than fastboot erase userdata)
After the reboot the phone shows the "warning bootloader unlocked" screen, a short vibration, keep this screen for 30 sec, and then turns off and do it all again.
When I try to get into recovery mode I see the "warning bootloader unlocked" screen followed by a broken droid image with the writing "No command."
Any idea on what can be done to save my phone?
Trying to restore on my other pc.
using "Moto X Pure 3r Gen (2015) - X2 WE-LTE-2CA - North America US Retail XT1575 MPH24.49-18_18.zip"
witch I once downloaded from Motorola, I run the first command:
>fastboot flash partition gpt.bin
And get this error:

what's wrong?
You might need a newer version of ADB/Fastboot. I remember having a similar issue previously when flashing a stock ROM and had to update my software. It's not a guarantee, just a suggestion.

Ooms
on my primary PC I downloaded "Minimal ADB and Fastboot"
and still the same error.
tested on my laptop (on it i did my first try) and here i can run this command

did a test and took a motorola logo from here http://www.droidviews.com/remove-un...ng-on-moto-g-moto-x-purestyle-using-fastboot/
opend and flashed it.
Now I have the M logo instead of the "warning bootloader unlocked" screen but still on the boot loop.
Very strange, but after only flashing the logo.bin, the phone menus in the fastboot changed abit (look to me like the old version) but still no recovery.
Also see that on "fastboot flash system system.img"
I get an error:
target reported max download size of 536870912 bytes
Invalid sparse file format at header magi
but than it sends the file and keep writing OKAY
So some thing is still working down there.... juts need to find the correct stuff to flash on it?
Solved!!
Ive tried some more images to flush.
at the end used XT1575_CLARK_RETUS_6.0_MPHS24.49-18-3_cid9_subsidy-DEFAULT_CFC
The phone did a very long boot but at the end it loaded into the system and managed to get my lost photos.
Then reflashed TWRP -> restored my last image and every thing is now working as before.

The bootloader has changed and phone is bricked; what should I do?

So I have run CandyOS for a while, but since it got bricked for some reason (possibly something to do with magisk modules) I decided to run another ROM instead. This is what I've done, keep in mind my bootloader has been unlocked the whole time:
1. booted into TWRP
2. flashed LOS 17.1 (gave error 18)
3. booted into bootloader in order to boot into LOS native recovery which I here realized existed (although their installation page says to use TWRP)
4. phone reboots into a changed bootloader which now claims "oem_locked"
The bootloader:
Code:
(in the middle of screen) Power off
AP Fastboot Flash Mode (Secure)
BL: MBM-2.1-river_retail-0ff2095b20-200404
Console [NULL]: null
Tools Mode Config: DISABLED
Battery OK
oem_locked
I've tried a couple of things, results below:
I tried to unlock the bootloader (I have the unlock code saved):
Code:
fastboot oem unlock XXXXXXXX (bootloader) feature disabled
OKAY [ 0.003s]
Finished. Total time: 0.008s

The exact same things happens with TWRP
I have also tried the Lenovo recovery program with no success, it refuses to recognize my device.
So what would be my next steps? Any help would be appreciated as I've tried to ask in a couple of places with no success
Did you try manually flashing to stock? If your bl somehow got updated to Android 10 along the way, it may explain some things. If stock 9 doesn't take, then perhaps try stock 10. :fingers-crossed:
