I'm running a V20 851 (TMobile) with CleanRom 2..6 (a stock Rom with bloat removed); Android 6.0, D85130g.

I lost root awhile back. I am trying to flash KDZ, but LGUP is not recognizing my phone. Help?
[G3 General] mrfreeman15:
So it looks like I screwed up and my phone seems to be soft bricked now. Here's what happened:

My phone is a D852 on Fido Canada (although unlocked now). I wanted to downgrade to LP from MM.

I followed the instructions in Post #3 exactly. I downloaded the TELUS kdz file from the Canada D852 folder in the link. I know its not my original carrier, but could that have made the difference? Maybe it could have and I'm just dumb.

Everything flashed seemingly ok but now the phone doesn't boot, after the LG logo it shows a dead android with the red exclamation sign.

I can still enter the hard reset mode (vol. down + power; although the actual reset doesn't work) and download mode (but I cannot flash anything in LGUP anymore; it crashes at 6% with the following error regardless of rom:

Error: [*Time of flash*] Open

Packet Error No :

0x80000001

I also managed to get into recovery once by pressing vol. up + vol. down + power, and wiping the cache partition, but that also didn't help (nor was I really expecting it to). But I never managed to get into the recovery again after that one time.

Can my phone be completely dead? It certainly doesn't look like a true, hard brick. I shall be forever grateful if y'all can help me figure this out.
[G3 General] Wade83:
when that happens just leave it and wait, it took me 5 mins to start loading the bar in download mode
[G3 General] yahya69:
Hi, how can I find the correct kdz? I don't understand the numbering scheme. I have a 16GB model, which says Software version V21a-EUR-XX, build number LRX21R.A1445306351. The device is on MM and I would like to downgrade it in order to root it, to install TWRP and ultimately flash LineageOS. Would Europe Common 16G D85510A_00.kdz be the correct choice? What file format do those kdz archives have, so that one can inspect its contents?

---------- Post added at 11:00 PM ---------- Previous post was at 10:44 PM ----------

Apparently there is no LP stock firmware for my region (common Europe) available. Can I also downgrade to Kitkat? I need it only in order to root it, install TWRP and ultimately flash LineageOS.

Video Viewer app

Hello,

I like to use VLC for viewing all formats of video files. VLC has the most complete set of codecs that I have seen. You can get it for Windows, Linux, AND Android as well. It also plays audio, and it has a file selection setup that allows for by artist, album, or genre.

download dll server down

hi!

The download for the .dll file is down... can you share it again?

Thanks for your work!!
[G3 General] hyelton:
What link? All the links in the OP are working perfectly

EDIT: hmmm weird, thanks for bringing it up! It was indeed not working. It has been fixed :)
[G3 General] Mapuku:
LG UP says unknown device and I can't do nothing.

Any ideas? is the phone for the garbage bin?
[G3 General] akmal18:
Search for proper dll file for your model. It will help you.
[G3 General] Mapuku:
i managed with lg flash tool.

and then insteaf of enjoying the phone - it restarts itself and stays on lg logo once again
[G3 General] akmal18:
Are you sure that you used the firmware for exactly your model?

If you have stock kdz firmware for exactly your model (d855, f400...) use Lg Flash tool. Otherwise search for TOT firmware, LG UP, proper dll file. If everything is right for your model it shouldn't be any problem.
[G3 General] Mapuku:
what more is there in a model than D855. i have the boc of the device. all i see is D855.
[G3 General] Vasello:
guys my phone is this: https://www.imei.info/?imei=355673063450964

how can I know which is the country it comes from in order to download the right files??
[G3 General] MaverickNextDoor:
From the model number, that's the international version of the G3. So it's not supposed to be region-specific like the carrier branded ones. Take a look at the video by @hyelton to see the file name of the TOT file he used (if memory serves well, he did a video on the D855 found on the first page of this thread also on YouTube).

I can't use the oceanhost.eu-links as well..

Is there a way to reupload them somewhere different? I'm a little stuck without the files it seems...

Thanks and best regards!
[G3 General] rahimali:
The files that have been uploaded to oceanhost.eu are already shared on androidfilehost as well (by other people, not myself)...

All you have to do is get the filename from the oceanhost.eu share and search for (and subsequently download) that file from androidfilehost.com.

I kept getting errors on the installation of the files (Win 8.1), so I'll try again at work tomorrow (Win 7) and I really do apprecicate the help!
[G3 General] cfelix:
Just a rehash of the instructions

I had a hard time getting this to work until I saw the YouTube video for some missing pieces. Like another poster said, check the video

https://www.youtube.com/watch?v=wJtcPNklrfw

Just a rehash of the original instructions with some of my added notes:

AT&T & Sprint Verizon & The Few International TOTs. Also T-Mobile Can be Flashed back this way if you are having issues!

DO NOT PLUGIN YOUR PHONE TO THE COMPUTER YET.

1. Install the LG drivers.

2. Install LGFlashTools (but don't run it)

3. Copy MegaLock.dll to C:\LG\LGFlashTool, This may be a hidden folder so enable "hidden folders". Replace the old MegaLock.dll file if you have already installed LG Flash Tool on your computer.

4. Extract the TOT file from the firmware ZIP

5. Launch LG Flash Tool. You will need admin privileges. You might see a window with Korean language, just click on OK.

6. Check the Manual Mode check box at the top of the LG Flash tool window.

7. Click the DLL box and choose the dll file downloaded for you phone model.

8. Click the S/W box and select the firmware file with the .tot extension.(the 2+ gb firmware file inside the zip)

9. Click OK.

10. Click the Yellow arrow to start the process. After a bit, the Flash tool is waiting for a phone to be connected. At this point you will see some CRC checks and at the end the Port 1 will say READY.

NOTE: To this point your phone needs to be unplugged. When you connect the phone the update will be triggered, but it did not work for me if the phone is already connected.

11. Boot your LG G2 into Download Mode. To do this, shutdown the phone, connect the USB cable and then press and hold the Volume Up key while you press the power button to turn on the phone.

12. Open the Windows Device manager. Open the Ports group, select the LGE USB Serial port, right click and select properties.

13. Click on the port settings tab, then click the advanced button, and change the COM port number to COM 41. Close down the Device Manager windows.

At this point you will see text scrolling in the box for Port 1 (below where it said READY) once the software detects the phone. Like the original post said, ignore the errors.

Hope this helps, and many thanks to all those involved with getting this to work, the tutorial, and all the help given in the forum!!!!!!
[G3 General] patman329:
Thanks tons!!!

Hunter,

I can't thank you enough!!! I had little hiccups along the way. Like the tot file would take forever to download and after a few hours, ,it wouldn'[t unzip, but I read that that was possible. I also think I had issues with Windows 8, but I have a loaner work notebook with Windows 7 and used that today and got all the files I needed. Then there were issues with the LG Flasher, but after a bit more research and a couple of other posts, I finally got through all of that. I must have read over 500 posts these last few days, since Monday morning. And every time I saw one of yours, I was thinking how frustrating it must be to have to go over the same information with different people every day and you don't even have the phone. Your knowledge is amazing. I really appreciate the help. I wasn't even sure it was possible and you gave me the push to keep at it. I'm guessing that you are in college? What's your major? Just curious! I do owe you a beer or two!

Pat
[G3 General] hyelton:
Your very welcome! When the files have issues using a download manager like free download manager will make it download faster and not cause corrupted file downloads. I only have an GED and with my low income and lack of time I cannot afford college at the moment. Computers and the Internet are just my thing :) I did own the phone at one point I personally didn't like it (I had the At&T varient and it seemed awful and slow but other variants seem fine) thankfully not much has changed, but LG is one of the worst for going back to stock, updating, etc.
[G3 General] Thot Ctrl:
Hi,

I am sorry if this sounds silly. Coming from a samsung device where rooting was pretty straight forward the new LG world is a bit scary for.. will this method work to un-root my D855 if I have the bumped TWRP and/or custom ROM installed?
[G3 General] hyelton:
Yes. This is for going to 100% complete stock.
[G3 General] Thot Ctrl:
Thank you very much for your response. My G3 is a bit new so I did not want to screw it up as I spent a lot of money on it :p
[G3 General] defens23:
Ok. I bought a new hd for my laptop and did a clean install of windows 7.

Downloaded all of the files. Installed LG drivers, and everything else per the tot instructions. I am still having issues getting the LG drivers to properly load. I downloaded the Verizon drivers since my LG G3 is a Verizon phone.

3.2) Download Drivers (Verizon Only) - LG_VZW_United_WHQL_v2.11.1.exe - 7.8 Mb

Getting frustrated beyond belief! This is where the issues start.

8) When the firmware is downloaded, boot your LG G2 into Download Mode. To do this, press and hold the Volume Up key and then plug the USB cable.

As soon as I plug the phone in the laptop wants to install the drivers. It seems to install the usb driver but I get errors on MTP and something else.

When I go into device manager I have nothing but exclamation points next to the LG driver. When I look into them it tells me the driver is not installed. I've uninstalled the driver. Rebooted the laptop after that and reinstalled. Should I try a different driver? What do you suggest?
[G3 General] hyelton:
Make sure you reboot your PC after installing drivers , also make sure YOUR in download mode. MTP shouldn't show up if your in download mode.
[G3 General] defens23:
I'll uninstall the drivers again when I get home tonight. Reboot the laptop. Reinstall the drivers and then reboot the laptop before I do anything else.

Thanks

Hi All,

I followed this guide in flashing a KDZ that has Android 5.0 Lollipop, I got the KDZ file here at XDA with the 85520D_00.kdz (Poland).

When I was already at download mode and flashing the KDZ via CSE method, the phone got stuck at 6% and the LG Mobile Support Tool is stuck at 12min mark, then the support tool gave an error upgrade stopped due to an error.

[IMG="error"]http://i59.tinypic.com/2uhohtd.jpg[/IMG]

Now when I followed the instructions to unplug the phone and power back on, the phne no longer goes to Download mode at all!!

I am stuck with "Fastboot" option at the start screen, is there anyway to fix this?!

Please help!!!

---------- Post added at 09:15 AM ---------- Previous post was at 08:49 AM ----------

Good god, I think I'm on the verge of a break down right now. I just bought this phone today, followed this guide correctly and had this happened.

Did I just brick my phone? :'(
[G3 General] pjl3dm:
Well I was able to fix my "fastboot" brick problem:

Just to share how I fixed it, I extracted the KDZ file compatible for my D855 and got the laf.img and boot.img

I then used Android ADB/Fastboot tools to push the laf.img and boot.img to get Download mode working again.

After I pushed the files, I was able to go in to download mode again, THIS TIME I used a Windows 7 pc (seems like the problem was windows 8.1 thats why the download to phone halted).

Flashed the same KDZ file (with Android 5.0 D85520D_00.kdz) via CSE method. Everything went well in under 1min.

Was able to get the phone working again!!

Thanks to the XDA members -- was able to find a lot of useful posts that led me to the fix.
[G3 General] ObsidianShadow82:
Thanks for the informative post. I have D851 and I've flashed it back to stock once already but I have a question I can't seem to find an answer to... How about a Linux Ubuntu method? I want to get away from Windows if possible but so far it's looking like I won't be able to. I even setup LGFlashTool in WINE but I'm afraid to try it because Linux does not use COM ports for serial bus so I'm not sure how I would manage to setup the program prior to flash... Any help would be greatly appreciated because I would really love to delete my Windows partition and cut the cord ;)
[G3 General] hyelton:
There's only a PC method. You can only do it on Windows. Its always been like that since way back with original LG androids. It's only doable on Windows. Only way would be to maybe do a virtual machine in Linux.
[G3 General] :
V20C to V20D

Which option do I choose to upgrade my V20C installed on my D855 to the newer V20D .kdz without losing all my data?
[G3 General] hyelton:
Youll loose data also when flashing its recommended to perform a reset as well

[G3 General] vineet381:
Please help, I flashed VT6 on my 400K, seems like my version changed to 400L, I am now getting error on start Unfortunately the process com.android.phone has stopped as well as process com.android.systemui has stopped. Trying to follow the process in OP to get to stock but not able to get into download mode :(

UPDATE: I am able to see my phone on device manager but dont see the PORT under properties (see attached), also once I press volume+ and plug USB, it starts booting and ends up with the error, not sure whether I am in download mode
[G3 General] Lostatsea23:
Does it let you tap things really quick?
[G3 General] vineet381:
Yes, I am even able to increase decrease the volume by volume buttons, I even have backup of stock in recovery but cant go there :(
[G3 General] Lostatsea23:
Try to go to the build.prop and edit your device name to the proper one
[G3 General] vineet381:
How do I do that, I am very noob in this, it only allows me to click OK on the error messages, as soon as I click OK, the msg appears again..
[G3 General] Lostatsea23:
You have to be quick. Click okay and swip and try to access the app. It takes patience
[G3 General] vineet381:
ok, I will keep trying but why cant I go to my download mode and change the port, see attached in my last 3-4 posts..I have all the files from OP, this is frustrating :(
[G3 General] Lostatsea23:
Delete driver fully from device manager then reinstall it
[G3 General] vineet381:
OK, also, shall I also try changing the USB cable, I am using the one which it came with it, I also have the cable from my Nexus 4
[G3 General] Lostatsea23:
Nope always use the one it came with. And make sure its not a USB 3.0 port
[G3 General] vineet381:
Thanks, I hope I am able to get thru this, I will PM u if u r okay with it, seems its gonna be a long night :(
[G3 General] Lostatsea23:
That's okay

I need to change Hutchinson 3 network rom with european one. My G3 in untouched yet. What do I need? root, twrp.....?

Reason is that current rom report to 3 network when I want to use hotspot. I had no issue with my htc m7.
[G3 General] buzniak:
All Versions?

Does this work for all versions, International!
[G3 General] hyelton:
If you read the OP this method goes back to 100% stock. Which means no root or non of that you use the programs in the OP. Also I don't recall the 3 firmware reporting anything via the hotspot feature. No matter what phone you use 3 will still know your tethering no matter what.
[G3 General] defens23:
Still no luck. This may be the easiest way to show you what I'm getting. Might even be easier just making the 2 hour drive to Wilmington, NC if that's where you're at lol.
[G3 General] hyelton:
Hmm try and go to LGs website and download the drivers from there by going to support and entering your model number.
[G3 General] defens23:
I have even tried this method. Not sure what to select because in the post the guy is referring to a 64 bit issues. I am running Windows 7 home premium with 32 bit. If that doesn't matter then here are all the options I have to select from.
[G3 General] hyelton:
32x and 64x doesn't matter for this. Also just select the folder and it will download what I needs.
[G3 General] defens23:
Went to the LG support site. Looks like there is an updated driver for the Verizon phone. Going to uninstall the driver I downloaded from the OP and try the new one.
[G3 General] flyingeagleage:
Thanks for reply.

If I share the net with my G3, on the other phone browser connected to it will pop up a page from three after u type let's say google address. Now that I have htc one max (with vodafone firmware) I check what u just said and put my sim card in it. Hotspot is working without showing three network website.
[G3 General] hyelton:
That's odd, but its not the phone causing that page to come up its 3 themselfs. If you flash another firmware that page will most likley still be there. You'll probably have to download an app like pdanet or something.
[G3 General] defens23:
That did the trick! Here is the updated driver for Verizon if you'd like to update for others. I can't believe it was something so simple as just getting the updated driver. Been pulling my hair out (what's left of it lol) for days. Thank you so much for your support.
[G3 General] hyelton:
When I get home I'll update the drivers the OP :)
[G3 General] defens23:
Well have a few beers or a good lunch. It's on me today. Thank you again for your support.

Will I have to do this every time they send an OTA with updates?
[G3 General] hyelton:
Thank you very much! Do what flash back to stock if rooted?
[G3 General] defens23:
I rooted it with IOroot. Will I lose root if I get an OTA update?
[G3 General] iBolski:
For some reason, Norton is flagging the file LGFlashTool2014.exe as malicious and removing it. It won't let me run it.

Any ideas?
[G3 General] ObsidianShadow82:
You can disable OTA updates through the hidden menu. Open your phone dialer and dial the number 3845#*[your model number]# to access. From there -> WLAN Test -> OTA Setting -> Disable. For example I have the tmobile varient D851 so I would dial 3845#*851# to access the menu.

I got you. I understand these toolkit programs only run on Windows, I'm just trying to learn and I've been looking all over the web for a way to do this manually, which should be platform independent since the Android SDK is. I've already got the JDK and Android SDK up and running on my Ubuntu partition and adb recognizes my device just fine. But I'm stuck at this point if I want to flash back to stock because there appear to be no toolkits for Linux... From what I understand, these toolkit programs are really just overlays for the basic functions already provided in fastboot and adb... So theoretically we should be able to flash back to stock using only adb and fastboot if the G3 is fastboot compatible (which it is). In that case, we would be able to do so from Linux OR Windows using only the terminal or command line, correct? Or am I misunderstanding this completely? I found this thread here:

http://xdaforums.com/showthread.php?t=1907796

But it's for a Nexus 7... I would imagine someone out there knows how to do it for a G3, have you heard anything about it? I guess I may have to dive deeper into fastboot and adb and learn more about them, and any help you can offer would be greatly appreciated. Thanks again for your time. Like I said, I'm just trying to learn so I hope I'm following all the rules and behaving acceptably here.
