I had messed up a couple settings on the custom ROM I was running. I wanted to get back the stock setting so I went to recovery and did a wipe. I rebooted and found I lost supersu. I went to reboot back to recovery to flash supersu and It wouldn't boot into recovery. I went to adb on computer and couldn't reboot it there either. I found I could put the phone into Download mode. I tried the flashtool and LGUP and neither will communicate with the phone to be able to flash stock firmware. I don't mind too much because I can JUMP, its just the boot animation says Xperia.
ADB commands only produce "Waiting for device"
Flashtool says, "Wrong dll file"
LGUP won't let me use a current KDZ but only a tot file and the only one I found is 10n.
Relevant thoughts welcome as I continue to scour these pages.
Apparently LGUP considers going from 20r to 20p and upgrade. Lesson learned. 1) When your phone is bricked playing with other tool settings can't hurt anything. 2) Sometimes the OP of a thread can be a little ambiguous, read and reread. If one thing doesn't work, check for (possible) variations.
I was using refurbish setting on LGUP because that's what seemed to apply.

Hi,
so I rooted my phone, unlocked the bootloader, installed TWRP, put in 3 different ROMs on my External SD card, went ahead, deleted EVERYTHING from the phone, tried flashing ROMs, not a single one worked.
I rebooted the phone because I saw no other option, TWRP said that there is no OS, I went ahead and did it.
Now the phone won't start, I tried returning it to stock firmware as per lg-phones website guide (worked before, though my phone was not this messed up, I could access download mode and now I can't), but I keep getting connection problems. I have tried doing this with the phone just "turned on", it hangs on LG logo for infinity.
When I try putting the phone in download mode, the only thing I get is fastboot. When I try to use adb devices and other similar commands, it says device not found or simply does not list it, regardless of the "mode" the phone is in. However if I try and use LAF RECOVERY MULTITOOL, it detects my phone and I can use fastboot commands. I have custom recovery, boot and laf imgs on my PC, I tried flashing them all, PC and phone tell me everything's ok, but when I restart the phone, I get nothing... what am I doing wrong, and can this be fixed? If you have any questions, I'll answer to the best of my ability.
Thanks in advance!
SOLVED!!!!
Just found a backup laf.img that enables download mode... PHEW!
Hey all, thanks for reading. I've caught myself in a predicament. I can solve most issues that crop up my way, but right now I'm a bit stuck. It is likely fairly simple and I am just dumb...
The huge issue here is that I am running stock lollipop for the D415 model. I am having the typical base-band and WiFi issue that a lot were having. Like most, I just booted up into TWRP and restored a backup. I Wanted to try again so I flashed the stock ROM and tried again; didn't work...oopss..
LG Flash Tool refuses to locate my device. Download mode fails to connect my device properly. Error is:
EP1/out FAIL nfo=40 pg0=ffbd880
usb_read() transaction failed
So now I am stuck with a broken stock ROM, no TWRP, and no current way to re-flash a stock ROM.
Steps taken so far:
1. Reinstall all drivers
2. Attempt to root and install TWRP to access my backups (No access to Download mode)
3. Started all over with original USB.
What can I do? Thank you again for reading my long post.
Came back to it after a few weeks and issue has been resolved. Despite error warnings fastboot operated correctly, only manually. Any script etc. that booted device into fastboot would never find the device. Simple as flashing recovery and restoring a backup.
tl;dr: I'm not very bright.

EDIT: Forgot to include that I see the proper devices in device manager.
EDIT 2: Device is properly configured and can be found in ADB when powered on.

where u able to fix it? i currently have no recovery or OS it just stays at the LG screen i can only get into Download mode i tried to flash a kdz but it cant read my phone....it turns on but thats it i cant got past the LG screen and when i connect my phone now i get different device drivers than before like LGE AndroidNet USB Serial Port and USB Modem....idk what to do
Well I was dumb today and thought I'd see what happens when I go and lock the bootloader on my tmobile G4 with Genisys 4.9 installed. I was going to replace it anyway it was giving me issues. it started bootlooping with error 1003. No prob, I bricked this thing before. But now LGUP will not recognize the model. Model is Unkown, and COM Ports are COM4, Genisys. I've tried just about everything I can. I think my issue is that LG isn't seeing my device as a H811 so it won't let me force it to restore. Are there other ways that I can restore, since I can get into download mode?

Yeah, see the problem is that LGUP isn't reading my h811 as itself, just saying unknown model so I can't flash with itg
So to go more in depth and kind of bump this thread, I cannot enter recovery. I can get to where it asks me twice to confirm resetting but instead of entering twrp it goes back into the LG bootloop. My biggest thing is I need adb, but I can't figure out if I can access it on this device, since I can't boot into the OS or recovery. I think the custom rom I had on it, Genisys 4.9, changed the model number in build.prop so the LGUP tool only sees it as an unknown model. If I could just force LGUP to think it's the H811 it is then I could probably flash it. LG Flash Tools always get frozen at the network part. Well since the entire problem came from my using "fastboot oem lock" while on a custom rom, so I assume I just need to "fastboot oem unlock" to fix it. God this has been such a pain
I found a similar thread: Stuck on LG Bootscreen only download mode, LGUP didn't work that DIDN'T have an answer, in case anybody asks.
Basically, no fastboot, no recovery, download mode but LG Flash Tool 2014 AND LGUP don't seem to recognize it.
I was originally on the latest T-Mobile Firmware, then I unlocked the bootloader, installed TWRP, and installed the H-ROM.
I don't remember what exactly happened, but a bunch of factory resets and a few reboots into and out of TWRP later, I'm assuming I've bootlooped. Neither LGUP nor LG Bridge will work, but I can still boot into download mode. Is the only solution really the freezer/hair dryer method, or is it possible to use software to fix it?
Please delete, this thread is no longer needed as the phone is currently fixed.
Hi everybody
I need to find an update.zip to flash it on stock recovery and attempt to repair the phone system.
Long story short..
I restore my D415 (previously with Lineage 14.1) to stock firmware (KK) via KDZ file and LG flash tool, then update it to LP with LG Mobile Support Tool and everything was good, then i tried to root the device with the LG OneClick Root (which i used several times before to root my phone without problems) but i don't know what happened during the batch process and now Download Mode has been replaced with Fastboot mode and the device hangs on the T-Mobile startup screen, so i can't flash a KDZ file again to restore the phone without a Downlaod Mode. The fastboot mode throws "remote: unknown command" with every command i tried (except fastboot getvar all; which shows "unlocked: no") even reboot doesn't work.
Tried everything even booting on Qualcomm Qdload mode (shorting the phone with test points) to reflash the firmware files but couldn't succeed because QFIL, QPST Software Downloader and BoardDiag they all threw errors.
I can access the stock recovery mode by pressing home button when the "erasing" screen appears after selecting "yes" on factory reset menu, so i need an official update to try to fix this phone, don't know if its gonna work or if this is a hardware issue but at least i want to try. Buying a new one is very difficult for me right now.
Thanks for any help.
