LG V20 has no power for download mode after flashing H918 ROM over VS995. - LG V20 Questions & Answers

Hello guys, I have a used unlocked LG V20 Verizon VS995 but it is very selective with SIM cards. Some worked and some didn't. The phone dialer couldn't also dial special codes like the IMEI checker, phone testing code or LG MENU. So I thought of getting other ROMs to flash in place of it. I flashed the H91520a ROM with LGUP using the partition dl option. It worked at first but still gave the same SIM card issue but even worse. So I flashed back to Verizon.
Before I reset the factory data after flashing, I remembered I had some Tmobile H91820h KDZ for my previous V20 lying somewhere on my PC. I flashed it using partition dl with LGUP again. When the flashing was done the phone didn't boot up any more. I removed the battery and tried to get into download mode (by holding the volume up button and plugging it to my pc) so I could easily flash back to the Verizon version again since nothing seemed to work well. The phone has shown no sign of power since then. Can't boot to fastboot or download mode. The LG startup logo doesn't even show up at all.
However, When I connect to my PC, it pops up under "Ports" in my device manager as "Qualcomm HS-USB QDLoader 9008(COMxx)". LGUP or LG Flash Tool doesn't recognize it. I really hope it isn't bricked beyond recovery.
Please, I really need help with this. Thanks.

I honestly thought the worst thing that could happen to a bricked device was boot loop. I just need to get into download mode. This is really saddening as it is my second V20. Thanks a lot though.

LG G2 D802 Bricked

Hi All,
I had TWRP recovery on this LG D802. Because download mode wasn't working i flashed a stock recovery. Since that moment i don't have:
- Recovery mode
- Download mode
- Fastboot mode
The phone is in a boot loop though. It flashes the LG logo on and off. The phone isn't being detected by the computer.
I hope someone can help me.
Kind regards.

This is not to dampen your spirit but if it is not detected by computer then it is very hard to get it back to life. But I guess it is not detecting by computer because it is not fully loading(at least some of the necessary files loading). If you aren't able to get into download mode or fastboot mode, I guess you may try the method explained in this thread: http://forum.xda-developers.com/showthread.php?t=2582142
Hope your device get back to normal following that thread, you need Ubuntu for that method to try, but that's(installing ubuntu) not a difficult.
Thank you for your answer. Onfurtantely that is not helping because for that manual the mobile needs to be detected by the computer.

Then I suggest you to completely switch off the phone(I hope you already done that) & leave it for some time and then try it after some time. Did you use the proper stock recovery when going from TWRP to stock recovery(I mean the recovery that is intended for your phone model)?. What I think is that as long as it is seeing some sort of life(it is going as far as LG Logo), there is a hope that it can be recovered. I think some thing is messed up in recovery or boot or one of those partitions that are checked during the boot.
You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too

ok stop copy pasting same thing on different places if you would have read you would have noticed in the beginning he can't eneter download mode
On which system did you try it?
Maybe try Windows,Mac and something like Ubuntu.
Also take a look at this http://forum.xda-developers.com/showthread.php?t=2582142
It worked for me, maybe it does for you too.

Fastboot issues and corrupted download mode.

I recently got my hands on a bricked LG G2 D800 because i thought i was deemed unbrickable. I got the device the backlight showed life and that was about it. i managed to somehow get (this method i think) it to boot to the LG logo and than it jumps to fastboot mode.
Yea me!!! I got fastboot and this phone is as good as fixed. NO! fastboot does not work. It will absolutely not execute a command besides "fastboot devices" to which it brings up a fastboot device. Since i got fastboot my plan is to follow this thread to recover the device. i updated all drivers that i need for this device, nothing. Plain and simple, there is an issue getting fastboot to execute command. the commands appear on the device but it doesn't advance further.
Download mode. Yeah i get the download mode that I get is a "security error" so its not the traditional download mode. if i get download mode i can flash a .tot right? Wrong. Fails due to "model information check". i got the phone to appear under COM41. The .tot file is 'LGD800AT-01-V20c-310-410-FEB-02-2014+0.tot'. Drivers does not seem to be the issue at hand, unless maybe its the ADB/fastboot drivers which i also updated to newest version.
The next thing im contemplating if this method is worth the shot. I have it booting to fastboot. I will probably do this since its probably the only thing left to try. Going to set up linux now so i'll report back.
Any help/insight will be appeared and properly thanked for.
I also got security errors on an 802. I was about to leave the phone in download mode and ran the LG Mobile Support Tool to perform an upgrade recovery to get a stock LP ROM onto the phone.

Link(s)?
I just downloaded the LG Mobile tool from LG Canada. Just search for the d802 and download the program. The program should detect your phone and download the correct firmware.
http://www.lg.com/ca_en/support/software-manuals
I actually have the d802 and it worked with the LG mobile program from the Canadian website.

I restored my phone using Win7 and I think there are some LG programs that do not work properly with Win8/10. I think one tool is the flash tool.
Does anything appear in Win10's device manager when the phone is connected?

Guidance required: H815T TOT antirollback version is smaller than device version

I got my lg G4 h815T with H815t10H installed on it, few days back.
OTA and LG Bridge
Checked OTA update and it stated that device is updated. But LG Bridge showed H815T20D is available. So i started the update process. But it stopped with an error at 80% approx. It gave a retry option.
But the error persisted.
LgUP
Then i downloaded the H815T20D manually and tried LGUP. It gives
Error code:0x2000, TOT antirollback version is smaller than device version
Click to expand...
Click to collapse
Then i downloaded H815T10H, thinking may be if this gets flashed then i may flash 20D. But it still gives the same error.
LGFlashTOOL2014
Then i tried flashing H815T10H using LGFlashTOOL2014 . It started the update process (going into LG User support tool). Completed 100%.
Phone restarted and BLANK. no nothing. no life.
QFIL
I then used qualcomm 9008 method and flashed 991 recovery.
TOT
====
Download TOT file "LGH815AT-00-V10h". Tried flasing through tot method. LGFlashToolv1.8 can read imei and serial but process stops at 9% with an error.
Currently
=======
No LG logo
Can get into recovery mode.
LGUP and LG support tool recognize device in Download mode as H815T10H
When tried to flash kdz using LGUP getting same error.

Sounds like you may not actually have an H815 but maybe a Sprint or Verizon or other mode.

Did you check your IMEI online to see if it shows the same model as well?
Only real way is to take the phone apart.

Here is IMEI report, it says LGH815T.
New thing is operator is OPTUS while i got carrier free. May be Optus rom will work. Lets try it.
Update
====================================
I already have tried H815T20d_00_0120.kdz for OPTUS H815T same error given by LGUP i.e. TOT antirollback version is smaller than device.
Infact this was the rom downloaded by LgBridge.
Any other suggestions.
Since you have already flashed the sprint firehose file with QFIL you may want to check out the thread by @steadfasterX below. He is working on a BL unlock which may be able to revive your phone to some sort of working order but has some limitations as it is still in testing.

Thanks for replying
Alright opened my mobile and surprise is that mainboard is EAZ66585501_H810_MAIN_1.0
so it is H810 not a H815t and surely a refurb
Now the question is how to flash a H810 rom.
currently it can be restored in bulk mode using Ls991 recovery, then if i apply tot method to flash H810 tot it gives an error saying "991 cross to 810".
Please suggest.

Still i can share the whole info [as it is on back of the mobile] with you guys in hope of further info:

Please remove your imei info from your post. Its not good to expose that.
Your serial looks odd by the way.. Usually it starts with 5xx, 6xx or 7xx.. So I assume it is the 665
Try this:
Pull out battery disconnect USB cable to your pc.
Insert battery and wait 5 sec. Then press vol down and while keeping it pressed plugin the USB cable to the pc. After 10 sec latest you hopefully see the fastboot screen.
If not :
Do you have Linux or a live cd like FWUL?
What I currently try to find out is if you're screwed or not. That means when you have used the qfil method it is likely happened that your device now is converted to a ls991 because of the qfil files you flashed!!!!
That's why I warn everywhere to not use the qfil method until you know about the results.
Let us know how it goes.

LG H870 stuck in LG boot logo after Oreo update. Nougat is working....

I have the LG G6 H870 single sim version, and it's a strange thing.
The Lg G6 remains locked on the LG logo, wait 15 minutes or more.. and does not go any further regardless of flashing method, LG Up or LG Bridge. Now it has the 11th global version installed. Using Uppercut and any version of Nougat starts right after the update. Any version of Oreo, flashed with LG UP or LG Bridge (LG Bridge detects that updating is required and proposes the V20b and installs it) remains stuck at the LG "Powered by Android" logo. It appear on Windows device manager, connected after boot like Serial device, so it's stuck in some Download Mode i think, and after pressing Vol down and power, it enter without problem on Download mode... pressing Vol Up and conecting cable in one second before reboot....
I tried both the bootloader locked and unlocked. The same problem every time. Oreo does not appear as OTA The check now for update message is: "You are using the atest software version for current OS".
Any idea is welcome. Please help!
I have the EXACT same problem.
Any help guys?

I have the LG G6 H870 single sim version, and it's a strange thing.
The Lg G6 remains locked on the LG logo, wait 15 minutes or more.. and does not go any further regardless of flashing method, LG Up or LG Bridge. Now it has the 11th global version installed. Using Uppercut and any version of Nougat starts right after the update.

Still stuck on Nougat...it refuses to let me go back up to Oreo.
Tried numerous .KDZ of Oreo, numerous flashable zips of Oreo.
Do I perhaps need a different kind of .laf or boot.img etc?

....IAM SOOOO Greatful.
THANKYOU!!!
You have 100% fixed my phone...u are a ABSOLUTE LEGEND!!
You one of the VERY few good people on this LG G6 forum.
Sooo many just dont even attempt to answer someones question.
I've owned stacks of smartphones and been a member of loads of XDA forums, but I have to say, as far as getting help asnd questions ansered etc....this LG G6 forum is the absolute worst.
Apart from youself, of course.
Iam now over the moon happy, coz you made my phone work again!
Thanks again.

I have the same problem you described.
Could you give me a link to the dll file? I can't find a file matching my phone LG G6 H870. Always getting this error "please, install valid DLL package(*.msi). for the model"

Thank you very much!
For me this method also worked.
At the beginning I had the same problem as before (error about missing dll) but launching the application as an administrator helped.
