LGv20 not booting into Bootloader H918 - LG V20 Questions & Answers

Hi,
I have a H918 its not booting into download mode it just reboot continuously
I can get into to fastboot but not download mode no matter how many times i have tried this it doesnt work, i used a different battery.
From fastboot mode i tried flashing the recovery img i get an error saying remote unknown
Please suggest if there is a way to fix this phone any help would be much appreciated.

Fastboot IS bootloader...

i mean download mode not bootloader sorry for the confusion

With your device powered off, hold vol up and then plug it into a computer. That should bring up download mode

i tried but it shows download mode briefly for few seconds then it tries to reboot and repeatedly reboots i have done a factory reset but nothing really works
It can only boot into fastboot mode nothing else, after factory reset it will get stuck on the LG logo and will not boot

Bump

You flashed a modified boot, laf or recovery without unlocking your bootloader. You can TRY doing a fastboot oem unlock while in the bootloader, but if it fails, there is nothing you can do to fix your phone.

My bootloader was always unlocked, I can lock the unlock and lock the bootloader but cant boot into the download mode.. looks like i bricked my device for good

Try grabbing system img and flashing via fastboot, or about img

[Q] TMo LG G2 help

After messing around with my phone and hoping to gain more storage space, I formatted my internal drive(via TWRP) without thinking of the consequences.
Background: my phone was rooted with TWRP v2.6.3.2 for recovery.
Now my phone is stuck on bootloop with the LG logo on the display. I connected the phone to a PC laptop and it's not being detected for obvious reasons. I am unable to enter download mode but can get to TWRP recovery. I tried method 2 here since I don't have ADB access, http://forum.xda-developers.com/showthread.php?t=2451696 but no joy.
Where do I go from here? TIA.
Since you can still access your recovery, try flashing a new ROM. I don't know why you're unable to get to download mode. If due to a miracle you're able to get to download mode, follow these steps to restore to factory settings.

For download mode hold just volume up, then plug the cable in.

Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.

I realize your rebooting to download and not recovery - but I have a good idea that the above might just work for you as well. If not - just use adb to push twrp recovery to the phone and if it bootloops twrp - try above post.
Above is correct
You can also try to use fastboot
Fasboot erase misc
Fastboot erase fota
Then fastboot flash recovery recovery.img
Replace the last part "recovery.img" with the twrp image name or rename twrp to recovery.img
Once done then pull bat. And do above button combo to get into twrp

I'm sorry for your loss. To me it sounds like something may be physically damaged.
To elaborate a bit further, fastboot doesn't usefully exist without root, stock recovery can only wipe your userdata, and you've already said download mode reboots way too early to try anything. There is no safe way to try anything with the firmware, if it even somehow is a firmware issue. There's the leaked firehose, if you force it into 9008 mode, but that's risky and I have no personal experience with it to give more details.
Basically don't expect it to be coming back.

Without it already being rooted and the dirtysanta bootloader installed there is no fastboot mode on anything (which you would have seen if you had read the OP) but the h918 (which still can't flash with it) and us996, and you still need a working phone to actually set the options in Android to allow unlocking the bootloader.
And I'd put it at like an 80% chance it's hardware failure anyway, since it's boot looping in download mode too.
Try holding down volume down and plugging in USB.......
Same issue herewith...
LG V20 boot loop , restarting again and again , also when USB cable method is applied to enter into the Download Mode , it also restarts after sometime after showing download mode icon etc........

Question Help with Nothing phone stuck in Fastboot mode (A13 Beta 1.5.1)

Hello,
I was trying to downgrade my phone from the beta to Android 12 and it's now stuck in Fastboot mode. Won't let me enter recovery. Tries to boot but just stays on the nothing logo. My bootloader is unlocked. I'm assuming I need the same firmware I was running to reload onto the phone. Any other files needed?
Thank you so much! cheers

I can't enter recovery mode. Only fastboot.
Flash boot and vendor_boot and you'll be right back in recovery
If it's not booting try set active slot to either a or B and flash the images mentioned above

I'm having a similar issue coming off a fastboot stuck device. I guess I managed to delete the recovery mode from slot B so I can't get into fastbootd to flash some of the lower level partitions to make my fingerprint sensor work.
The vendor_image is the recovery?
Did you guys find any solution? I am stuck with my phone stuck in the bootloader mode and I can't seem to do anything.
Here's what I did:
1) Unlocked bootloader while being on NOS 1.5.1 Beta. Successfuly did it.
2) Restarted my phone to bootloader mode and flashed dtbo, boot and vendor_boot from SuperiorOS 11th Feb build.
3) Proceeded to restart to recovery as mentioned in the instructions but instead of restarting to recovery, it restarted to bootloader.
4) Stuck in bootloader mode ever since!
Nothing seems to be working. I have tried literally everything but cannot get past the bootloader. Please help. I don't have any secondary device to use.
