make hard-reset:
a) Turn off the phone. If Power Off not working, remove the battery.
b) Press and hold ‘Home’ key and ‘Volume Down’ key.
c) With these 2 keys pressed, press Power button and hold till phone starts to boot in reset mode.

Thank you a lot of combinations of 3 booton Home, Volume Down, Power solve the problem thank you very much
I would really like to return to Froyo, but... I don't understand what rajko34 did.
Like, the v10 baseband is available but where I can get a stock froyo rom to flash with the LGMDP.exe?
If I flash with KDZ, the baseband is flashed/downgraded too?
Thanks in advance

Hi,
I am replying to this post just want that other should aware about the facts that Downgrading from 2.3.3 (V20) to 2.2.2 (V10) is possible and is successful using KDZ. You just have to take care of some below Points before flashing:
I AM NOT RESPONSIBLE FOR ANYTHING GOES WRONG TO YOUR DEVICE. TRY ON YOUR OWN RISK
1. Always Use latest driver from LG and make sure that your device is disconnected and any previous version of drivers should be uninstalled from "add and remove programs" using Windows XP SP3 system (Including LGE Virtual Modem,etc. etc. ..!!! (The one who already have latest drivers and clean PC won't find "Virtual Modem" in the device manager, So just Chill ) ..Check device manager and uninstall if they still there and also uninstall drivers from other vendors like Nokia, samsung, etc.
2. After uninstalling drivers , restart your system and make sure that your user is an administrator and then install New LG drivers from the LG official website (Just Google== LG P500 drivers ). and Disable LGE Virtual Modem if still its appearing in the device manager.
3. Always make sure that USB Debugging is enabled on the device and your system supports USB 2.0 (High Speed), so notification like "Hi-Speed device is plugged into Non Hi-speed USB" should not appear.!!
3. Extract KDZ_FW_UPD_EN.zip and Install msxml.msi and reboot your system again.!
4. Again you need administrator.!
5. Now Plugged the Device via USB.!, System will install drivers for your device. Wait let the system completes the driver installation .!
6. Unplugged the USB from the phone and Restart the Phone.
7. Wait for the phone to Boot and load completely (Approx 5 minutes).
8. Set Display Brightness timeout to 30 minutes and ensure USB debugging is ON.
9. Plug the device again and keep it at a place where it will not get disturbed. (Also ensure that You have Good working Data Cable, Hope Your Original one is still alive )
10. Open KDZ_FW_UPD.exe, select type "3GQCT" and phonemode "DIAG"
11. Click browse and select "V10E_00.kdz" file from where you have download it, I have used Indian version because I have Indian LG O1. (I recommend V10E_00.kdz because i used it twice and it works lika a charm :victory: )
12. Now the Flashing Part .! :fingers-crossed: ...!!. Click Launch Software Update.!
13. The phone will goes to Emergency Mode (Don't panic).! and the flashing process will start.. ! wait for flashing to complete.! Ensure that your system will not goes on Standby or sleep.! And If you are using a Laptop I suggest you to plug in the power first.!
14. I always make my mouse moving while flashing process is in progress. It make me feel better . So you can also try this
15. The flashing process may take 5-10 minutes to complete. and you phone will restart itself indicating the offline battery charging screen.!
16. Wait until KDZ prompt "FINISHED" in the end of the log.
17. Unplug the USB and wait for 5 seconds and press and hold Home+VolumeUp+Power simultaneously for Hard resetting the phone .
18. When The screen Shows LG Logo leave the buttons and Hard reset will take half a minute to complete.
19. Wait and Let the device Boots ups completely. (First Boot will take 5 minutes to get you to the lock screen)
20. Done.!! Congratulations.! You are now Downgraded to 2.2.2 . :highfive:
Good Luck :good:
IF anything went wrong during the flashing process or KDZ gave you any error in between the process.! Please DONT pull the battery out from the Phone. Else It will HARD BRICK YOUR PHONE.! And u are not even able to get the phone Power on..I mean Dead! Just Find Support on XDA and try and try again.! (Also suggest you to do not unplug the data cable, it may also lead to HARD brick the phone.)
In this situation ensure that you have a right flashing KDZ file. and IF you have the right one use different "phonemode" like Emergency, Emergency_CS, etc and try and try again.!
IF still wont work try to shake your phone and touch the screen again and again and try to launch the software upgrade
If still device is not responding try lgmdp method and try to flash a recovery and Image.
If nothing works restart you system and then again launch the software update in emergency mode.! (This option works for me once but i recommend you to try it as a last choice)
Don't pull the battery out and ask for support on xda.! Might be someone save your phone's life.
If the phone is still stucked you have to get it to the service centre. (If your phone is in warranty they will replace the PCB free of cost)
HEy guys after rooting my phone and booting it up it worked fine. After a couple days i decided to flash a custom rom to it. All went well and after flashing is said to reboot. After it shut down there was nothing. I cant boot to recovery or even to the LG logo. After holding down the power and volume down button for 20 seconds the red led will blink for 8 seconds...then 8 seconds more and it will do that for ever. Plugging it into my computer the computer will open up like 15 partitions. saying i need to format before i can use it. Now i did back up the phone before flashing and i have the file on my computer. How can I fix this?

Hi, so i tried to get cyanogenmod working on my g3 earlier yesterday and when i rebooted after installing twrp through the google play store it displayed the lg symbol, then displayed the lg symbol with "Security Error" under the LG, then turns off. I got the phone into recovery mode, then when i try to factory reset it has an lg symbol for about 1 second, then the screen goes black and my notification light blinks red/orange and blue. please help I dont know much about rooting my verizon lg g3 came rooted when i bought it used
Go back to stock
If it were me, the next thing I would try to do, is to get the phone back to 100% stock. Then you will know exactly what you have.
Try this:
Go find the link (I don't have it offhand) for the LG USB drivers and install them.
Plug a compatible USB cable into your PC.
Power off the phone and let it sit for 20 seconds.
With the G3 still off, hold down the volume UP button, and while holding it down, connect the USB cable to the phone.
You should see a "Download" mode displayed on the phone.
If that works, you now have a high percentage of success.
Go find and use the "LG Flash Tool 2014" to flash a pre-Lollipop KDZ file (eg, 12B). Use "CSE" mode, not "Normal" mode.
Thanks, but still no luck

maybe try a different usb 2 port if you have another one. other than that i wont be of much help.
i never bothered to learn the kdz process. the tot process always worked well for me, so i just stuck with it. unfortunately the tot's arent distributed as widely as the kdz on this device.

When you say it fails are you only thinking it fails because LG Flash Tool 2014 throws an error dialog up? If so, don't touch the dialog next time. You can move the dialog out of your way if you need to, but don't click any buttons inside the dialog. 99% of the time, if LG Flash Tool 2014 puts an error dialog up, if you just ignore it, it will actually flash your device. This isn't always the case, but literally almost all of the time. When this happens, it can take longer for it to start the actual flash process, so on the VS985, I'd wait 10 minutes before I'd start to worry.
On my VK810 tablet, it's up to 20 minutes.
If this is a different problem altogether: As @bweN diorD said, try another USB 2.0 port. When you put the phone in Download mode, check Device Manager in Windows, look for the LG entry in the Modem section. If this isn't showing up (could take up to 5 or more minutes to load the driver you previously installed, the first time you plug the phone into a different USB port while in Download mode), then you'll have to solve this problem first.
Let us know what the status of things is based on this information.

I was in the process of installing a new rom on my phone, I have been rooted for months,everything was fine, now when I installed the new rom via TWRP and rebooted my phone wont turn on, I just get a flashing notification light alternating between blue and green and it just sits there, I can't even boot back into recovery using Volume down + power, I just get a black screen.

so it seems like my phone is working in the background, but the screen is still black, if I tap things I can hear noises, I think I hit the emergency call button and was hearing the phone being dialed.
So now I need to find out why my screen would just go out like that, and if its the brightness that is completely low or something else.
if I plug in my phone to my computer and pull out the battery, my screen turns on with a flashing missing battery box and I can see the background of my phone, but I can't do anything else.
This kind of problem is commonly caused by a mismatch in partitions from various versions. Am example would be if you flash the 35B bootstack and then after that flash either JasmineROM 9.0+9.1 or SkyDragon 6.02, and you don't reflash the 35B bootstack again after that.
Both of those ROMs have an incomplete collection of partitions from 24B which would overwrite the ones from the 35B bootstack, and the mix of the 24B ones with what 35B ones that weren't overwritten results in that.
If you go through the motions of putting the phone in Download mode (you can pull the battery to make sure and stay with it off), and if you already have the Verizon LG drivers installed, you can see the phone is in Download mode by looking in Device Manager in the Modem section.
Use LG Flash Tool 2014 to flash the 10B KDZ, re-root with the Stump app, put TWRP on with TWRP Manager from the Play Store, then reflash what you want.
If you want the 35B bootstack on either of those two ROMs, flash it after the ROM, not before. If you don't want the 35B bootstack, flash the 24B bootstack before flashing the ROM.
I can't get the phone to go into download mode, with the battery off, the second I plug into my PC the phone turns on instantly into a faded setup wizard that looks like it has 2 wizards over laid on each other and in the middle a dark cloud with a battery icon and flashing red question mark.
holding volume up and power won't do anything.
Also my pc is being stubborn, I installed the LG g3 Verizon drivers and it shows exclamation marks on the phone's entry in device manager, should I do this in windows XP?
so it seems my phone does go into download mode, the overlay I am seeing is the setup wizard for the phone and the firmware update screen behind it..
still can't get the drivers to fire up though

After having installed the Verizon LG drivers, I recommend rebooting the PC (with the phone disconnected).
The correct way to get into Download mode is by, with the phone completely off, press and hold the Volume Up button (but not the power button), then while continuing to hold the Volume Up button, connect the original USB cable to a USB 2.0 port directly on the PC, not through a hub) and to the phone. In a moment you should see the Download mode screen and you should let go of the button.
The first time you do this on a different USB 2.0 port, Windows can take up to 10 minutes to load the driver that you had installed. Leave the phone connected for at least that long and then verify if the icon in the Modem section of Device Manager looks normal then, not with the exclamation point.
Edit: I didn't see until later that you say it does go into Download mode - never saw the Download mode overlaid by the phone setup wizard. If that's accurate, something's weird since Download mode doesn't get loaded in Android.
I think this phone is shot, I followed your instructions, the phone boots up to the firmware upgrade screen but I can still see "setup wizard" behind it really faint, and the PC continues to not recognize the phone

Very, very strange.
You can't get into TWRP either? Hold Volume Down and while holding it, press and hold Power, then when stock recovery pops up, let go of the buttons, and use the volume and power buttons to select Wipe Cache or Factory Reset - either should take you to TWRP.
What ROM did you install, anyway?
If you can get into TWRP, try flashing the 35B bootstack from @xdabbeb 's VS985 v2.0 ROM thread in Devleopment, then try to get into Download mode again. You might even be able to select from TWRP's reboot menu off the main menu, to reboot into Bootloader, which I think takes you to Download mode too. I haven't actually tried using it that way too - I'd try the regular way of getting into Downloade mode first.
I just did the same thing to a send LG G3 I bought, you gotta be kidding me....
Tried to install Jasmine 9.0, then updated to 9.1 and ran the debloat option, that seems to be killing my phones, this was a $150 lesson that I am avoid Jasmine Roms from now on. I can restore the new phone either, won't boot up into recovery, or anything.
my PC picks up the phone, but the screen is black so I can't tell if its in download mode, and LGflashtool 2014 won't recognize the phone.
I am at a loss for words.

I forgot to mention in the JasmineROM thread - I think that was you talking about the issue there too, right? Even if the phone screen is black as long as you see it in Device Manager under the modem section, then you're in Download mode. Then you can use LG Flash Tool 2014. Make sure and give Windows up to 10 minutes to load the driver. Don't use a USB hub.
Pull the battery to make sure the phone is off. Connect your original USB cable to a USB 2.0 port on your Windows PC - don't have the phone end connected. Press and hold the Volume Up button, and while keeping it pressed, insert the USB cable into the phone. Even if it doesn't vibrate - that's okay, although it might, too. Let go of the Volume Up button after two seconds. After giving Windows enough time to load the driver, you should see it in the Modem section. If you don't see it, check under the Ports section and see what it says.
So when I plug my phone into my PC my device manger shows LGE Mobile for VZW USB Composite Device and it says this device is working properly, but when I try to run LG flash 2014, I get an error saying my Device isn't plugged in
well I got it past the "not connect" part but now I am getting a connection to server failed, try again in a moment

Just ignore error dialogs like "can't connect to server". Drag the error dialog out of the way, don't click any buttons in it. Within 5-10 minutes you should find your phone successfully flashed.

completely ignore it? because I hit "OK" and then on the screen screen my S/W upgraded starts and errors out at 4%
Ok so I noticed the progress bar behind the connection error box, but that is the same one that errors out at 4%. The only thing I can try now is the original cable which I don't know where it is, I've tried 3 different usb cables already though.
Use The Specific Trademark Program Of Your Device On your Computer, E.,g(Flashtool,Odin,) And Flash An Stock Rom On It

Yes, completely ignore it. Don't hit "OK" or any other button on the dialog, just drag the dialog out of your view if you must. It's common, it happens a lot although not all the time.

*Error Update* So with this leaked LP image, I've been playing with kdz'ing quite a bit and with a new Windows install I got to experience a few of the issues being reported by others that I have never seen, along with trying to troubleshoot some others. Did I manage to fix them easily you ask?? Hell yeah!
USB Disconnected Issue: This is a driver issue. Very easy fix, just download the latest Verizon drivers from the link I posted above and install them without phone plugged in. Power off phone, hold up, plug into usb and WAIT for download mode drivers to install (as stated several times in this thread). Click the balloon to watch the progress, this took about 10min on an i5/ssd machine - be patient. This is the predominant issue I think people are having. The drivers while in download mode are:
-USB Composite Device
-LGE Android phone or LGE AndroidNet for VZW USB Serial Port COM5 (this is the important one)
-CDC Serial or LGE AndroidNet for VZW USB Modem (this will fail if you are on a rom with certain VZW items removed - not a problem, its not needed)
-CDC ECM LGE AndroidNet for VZW NDIS Ethernet Adapter
If driver install fails, manually update them by pointing windows to the driver file you downloaded. I am not going any further here, use Google.
??????'s In The Field: easy, don't change region or language from Korean as stated in the OP. Leave it alone, it will flash in English I promise you. Result = all fields readable in English while running
Connection To Server Failed: Simple, ignore the window. Just drag it away, but don't close it. This is an offline hack originally indented to run online, deal with the window!
Progress Bar: The tool will initially analyze the phone, then when flashing starts, pay attention to the phone screen which will now say COM5. The blue progress bar on the phone is the important one. At around 80% on the tool screen, the phone will reboot. The flash is over and the bar will continue to progress into the 99% while rebooting - then the program will crash. You can disconnect now, you've been successful.

To enter download mode:
Turned phone off by removing the battery
Reinserted the battery without the USB cable plugged in
Pressed volume up and kept it pressed
Reinserted the USB cable while still keeping volume up button pressed
(As I mentioned, this didn't work the first few times around and I don't know why. Apparently, persistence paid off.)
To reflash the stock ROM:
Google-searched for this phrase: lg firmware h850
Note: I'm not yet allowed to post links. Your results may vary. There was a result at a domain which includes the words "lg" and "firmwares". That one I chose. Hope that's vague enough.
Also note that there are other sources of this image, I'm sure I've seen something here on the forums.
Downloaded the image H85020i_00_OPEN_EU_OP_0628.kdz (I had trouble with an image version that was less than 20i (10c I believe). Again, your mileage may vary.)
Booted into Windows because (sigh) LGUP, which is used to flash the above image onto the device, is only available for Windows
Acquired UPPERCUT along with the correct version of LGUP and the latest drivers
Started UPPERCUT which in turn started LGUP
Note: this will only work with your device connected and in download mode.
Selected the image mentioned above (click the File path column of the BIN file row if I remember correctly), selected upgrade, started and waited
Had a cup of tea to calm me down after a day's work of messing with my phone
After the phone rebooted, I reset it to factory settings
(you may run into an issue here with a password that you're supposed to enter, don't remember what I did there but as far as I understand it entering it wrong enough times will factory reset your phone as well)
[Optional stuff from here on out I guess]
Unlocked the phone again (fastboot flash unlock unlock.bin)
Flashed TWRP again
Installed LineageOS again
Hope that helps, good luck with your phone!
