[problem] lg g3 d855 unrooting and installing stock ROM from Fulmics 6.9 - G3 Q&A, Help & Troubleshooting

So I got my lg G3 a while back, and until a couple of weeks ago it worked perfectly fine, rooted, custom recovery and custom ROM's(currently running Fulmics 6.9 on it).
Then, I noticed it started to fade to black(a well known problem, not the subject of this thread), and I want to send it to a care taker, since technically the time period of warranty isn't over.
So, I began to try and unroot it according to multiple internet guides, failing time after time. then, I noticed I don't have download mode, and it goes into safe boot mode instead. On top of that, I can't access my bootloader. I tried several methods, some including LGFlashTool and LGMobile support tool but with no success. So, considering I'm not exactly an expert in this matter(I'm clueless about what to do) I come here with a request for help. Any help is much appreciated and I'd be happy to provide any extra information if needed. Thanks a lot in advance.

Take a look here, if you haven't seen that thread already. Since you are on MM right now, you need to use LGUP tool. The full instructions are in the Post #3 in the thread; just follow them. Note that you don't need to enter the DL mode - just keep your phone turned on, and plug into your PC. As long as you have proper drivers installed, your device will be recognized when you launch LGUP, and you should be good.
I personally haven't tried this going back to stock from Fulmics, but I did successfully use this method several times when I was playing around and trying to root my phone and install TWRP.

so I tried following the instructions in the thread you provided, but LGup doesn't recognize my phone so i cant enter it.
tried looking for a solution but i cant find anything. I'd appreciate it if you could help me.
Thanks.
EDIT: I've figured out the identification problem but lgup does require Download mode, it just enters it by itself.
this brings me to the original problem-I don't have download mode hence I cannot use lgup.

Hold VOLUME UP while connecting phone to pc and it will enter download mode. Then start LGUp and flash kdz by following instructions

When I try and start download mode it writes fastboot mode and then the screen goes black and the led flashes red and blue. I tried to look for a solution for it but couldn't find anything.

OK, this I don't know how to fix, sorry... I was thinking that you just can't enter the DL mode manually for some reason, so the LGUP tool would do it for you. But from what you are saying, it appears that your phone can't enter the DL mode, period. That's really weird, and I have no idea what can be done in this case...

Help - Stuck on Download Mode

I rooted and flashed Sphinx. The ROM somehow kept me from hearing the other person on the other line when making calls and they couldn't hear me. So I was trying to unroot by using the Flashroot tool method. And now I'm stuck on download mode.
I have a d855. How do I unroot properly and how do I get out of the download mode.
This is my first time rooting an LG phone :/

Hold the power button for 10 secs to reboot to normal. <<<<<<<< Depending on what you have done >>>>>>>>>>
ENSURE that no transfers or other process are in progress or you will have a bad day. I don't know what you have done on your phone but ensure you read the thread you are following completely.
Are you trying to restore to stock? There are a few threads that you need to follow exactly or you will brick your device.

The method failed, so I gave up and wanted to just reboot. Did a batter pull and was able to get to the factory reset screen, but it just loops back to download mode.

I don't have the links to the tread where I got these from but lets just hope I don't get banned.
1) go to download mode
2) install this and download the correct .kdz file for your phone
-Modelnumber is ...
-serial number is your imei number
- wait until the download is done
3) run the lgflashtool2014.exe from this zip
-Select type= cdma
-phone mode= Diag
-reset time=33000
-Should be like this when You run it
-select kdz file= is where you need to find the kdz file you just downloaded(step 1)
-then press cse flash
-in the now pop-up window select start
-select your language
-ignore error (cannot connect to lg server)
-check progress on phone up to 100% then boots in recovery installs and restarts
-wait untill it goes to the welcom screen then you can unplug
-now the most inportant step Like my post
to enter download mode do this:
--You must switch off the device to start the process.
--Then press and hold the “Volume Up” and connect the USB cable from phone to PC.
--Use the original USB cable. Because, other device’s cable may not be detected in the Computer. So, only we recommend it to use the original-- one that you got it when you bought the phone.
--Wait for the driver installation on PC.
--Then you will get the download mode screen in your phone.
--That’s it.
I have the opposite problem, can't get into download mode haha

I can't find the .kdz file. I have the D85010d.
Also, i ran the original lg firmware, I also get an error saying it was unsuccessful or i may have keyed in something incorrect.
When I run perform the TOT method, I get the "device model is different".
So, d85010d was stock and I flashed sphinx d855... where they incompatible? im assuming no because the phone ran fine aside from the issue i stated on the original post.
would like more help.

I was in your position. Once you enter the download mode it is *almost* impossible to get out without removing the battery. I've heard a lot of suggestions like pressing the power button for 10 or 20 seconds or even doing that in combination with other keys, BUT the ultimate truth is that you have to press and keep holding power button for at least 1 minute. I didn't time exact seconds, but it was ridiculously long time. Probably it will take you less time removing the back and re-sit the battery, but personally I hate removing the back without serious reason
About the second question - I was unable to flash anything in LG's download mode. I'm using Ubuntu + virtualbox (Windows 7 inside), but due to issues with drivers and/or virtualbox and/or usb port forwarding I was unable to reliably connect and flash the stock kdz image. Fortunately I've sent the phone back to the LG repair office and they re-flashed the firmware for me.

It is not exactly what you want, BUT at least you can get your latest, official KDZ file from LG.
Open in browser the following URL, but replace the xxxxxxxxx
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxxxxxx
where xxxxxxxx is your IMEI number
As a result you'll get an XML file that will contain the location of your latest KDZ update, which should look something like this:

If you can't get in that, then something very serious happened!
you sure you can't enter it?
Otherwise, it would mean you messed up the bootloader!
Did you fix your phone?

when i enter into download mode
flashtool says an error that
*cant change to Download mode*
Download fail
what can i do?
Hi guys, i know it's an old post but i get the same issue.
I was following this tutorial https://linustechtips.com/main/topic/1058206-lg-g3-lineageos-tutorial/
I was on lollipop.
I initially downgraded to kitkat (V10e) using LG UP and then rooted with purple drake.
In the following reboots, "kernel error" occurred.
So I tried to flash the kitkat stock version again but without success.
I'm stuck in download mode and tried to flash both the kitkat version, the lollipop and the marshmallow, through .tot and .kdz, I tried both with LG UP, LG Flash tools v 1.8 and with LG flash Tools 2014 but in all cases unsuccessful because the phone reboots before it ends.
Now I don't know what to try anymore. Do you have any solution, please?
Thanks in advance.

[Q] Help: Fastboot Mode Started

Hello Everyone,
I recently purchased a Sprint LG G3 (LS990) about 2 months ago. I wanted to do a different ROM for my phone. I had to downgrade the the ZV6 to the ZV4. All is well and the ZV4 was up and running. I then wanted to flash the Chupa cups rom and was unaware that it was not for my model.
I used the flashtool kit and it got to about 80% and error occurred. I was able to return to the download mode and thought that i should just run it again. I ran it again with the same dll and tot for the LS990 and it was telling me that my model number did not match. It changed it to LG D855. So I did some research and found this http://forum.xda-developers.com/showpost.php?p=52541840&postcount=934. I tried it and it did not work. It got to about 85%. I used the flash dll for the lgd855 and the ls990 tot.
So again i tried to go to download mode but this time around it will not go into download mode. As I hold the volume up button and plugging the usb to the phone, the phone will show the LG logo and then it will change to the icon "download mode" and then go to this screen:
[40690] Fastboot Mode Started
[40780]---reset--
[40780]---portcharge---
[40990] fastboot: processing commands
When I unplug the usb cord and the plug it back in i receive this:
[316240] ---reset---
[316240] EP1/out FAIL nfo=40 pg0=f885200
[316250] usb_read() transaction failed
[316250] fastboot: oops!
[316250]---portcgarge---
[316430] fastboot: processing commands
and it cycles back as i unplug and plug it back in.
I've tried again to run the flash but this time around, in the device manager under ports, the phone is not found. I tried using adb to list devices and it cannot be found as well. I spent a good 2 days not looking for answers but have not found them. If i could go back and get to download mode i can flash a different rom but my problem would be that it thinks my phone is the LGd855 but my phone is the LS990.
I also tried doing the the recovery by holding down the volume down and power button until the logo appears then letting go and pressing both again. The options were to run recovery or not. When i chose yes, it would restart and then stay at the LG logo. I thought it would take some time so i waited 10 min and still nothing appears.
So what are my chances of ever getting my phone back together? Should i give up and go back to best buy and try to get another phone and if so, will they know if i tried changing the rom and that voids any warranty? Help, what should i do at this point?
Please, Any help, comments, and suggestions would be greatly appreciated. Thanks everyone in advance!

[Q] Help to unbrick my LG G3

Hello friendly devs,
So I messed up big time. I updated to 23C via the OTA and then discovered I couldn't do everything that I wanted, so I searched around a bunch for a way to put TWRP on it (never had it on this phone before) and of course no good way. I tried flashing it, and I got the fun certificate verify error trying to get into recovery. I could still boot normally at this point. I should have stopped.
Anyhow, I found a post about flashing the 12b aboot and that would let me throw TWRP on there w/o downgrading and losing all of my data. So, I tried it. Needless to say, this did not work. Now, I cannot do anything really.
If I try to boot normally, I see the certificate verify error with the initial LG splash, then screen goes blank. One red LED and then persistent blue LED until I pull the battery.
If I try to boot into download mode, I get the same thing (except the download mode symbol - which stays until I release volume button) and then screen blanks, LEDS, etc.
Sounds like from doing some looking that I'm basically up a creek w/o a paddle. I can maybe try to get into qualcomm mode (but I haven't found out how to do this), and try to follow these: http://forum.xda-developers.com/lg-g3/general/fix-unbrick-lg-g3-stuck-qualcomm-hs-usb-t2933853.
At this point, I'm thinking that's my only option. Does anyone have another idea, or at least advise on how to get my phone to recognize as 'Qualcomm HS-USB QDLoader 9008 mode'
Thanks for your help...

Thanks @jac10000, I appreciate your help! Unfortunately, that set of instructions didn't work for me. I get an error that says ''Model information check failed' when i try the security error section. I think it could be that my phone won't even show as an LG device. The best I can do is QDLOADER (and even that with special drivers, it plugged in as QSUSB_BULK), even though I had proper LG drivers installed (from previously using ADB...that's how I borked it originally). Do you know of any other things I can try? I've done many at this point and am starting to feel hopeless. Thank you again for trying to help me!
You need a different set of drivers I think. I had a big problem with the qhusb_bulk mode but after installing the drivers I linked on my post in this thread it read as Qualcomm 9008: http://forum.xda-developers.com/showthread.php?t=3072091.
Try it out and report back to us. You should be able to then run the boarddiag tool as per the instructions on the attached pictures of the op in this thread: http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091.
Follow all the instructions very carefully and you should be able to bring it out of a bricked state!!!

I was able to get it into Qualcomm 9008 state, so that's a positive. I tried some similar, but I guess slightly different instructions using board diag and wound up with 'Failed loading flash programmer' errors. I'll try these other directions tonight. maybe if they're more specific I'll have more luck.
thanks again!

I have somehow apparently screwed myself over worse. Before about half the time my computer was recognizing my phone when i plugged it in, and with the drivers, as the qualcomm 9008. But now, I can't even get that! I plug it in in download mode, or normal, or not on at all and the computer doesn't recognize it. I've tried uninstalling the drivers, reinstalling them, rebooting, not rebooting. I opened it up to try and short the test pin, as the instructions stated, but there was a metal covering over the qualcomm chip which I couldn't remove. I am starting to think I'm screwed. I have seen lots of people having success with d550 and d551, etc, but I'm worried the verizon model is different.
thanks again for helping me. If you have any other ideas, I'll try pretty much anything at this point!

I had my VS985 hard bricked when I used "DD" command to mess around to try to put TWRP on it. I tried every possible method out there and I found that they don't work on VS985. KDZ and TOT flash all failed, no ADB. I tried it for 2 weeks and I gave up and sent the phone back to LG for warranty service. Guess what? Even LG couldn't fix it. They had to replace the motherboard! I would advise you the same path. Since your phone is so screwed, LG probably won't be able to tell what you did to it. Just play dumb and say one day you wake up to a dead phone. It worked for me.
By the way, who told you to put a KK aboot to a L rom? That seems to be a sure way to hard brick your phone. OTA does not work with a modified phone (no root, no TWRP). When you get your phone back from LG, TOT it to 10b, Stomp root it, and install TWRP manager to install TWRP. Then you can find the Jasmine flashable zip to upgrade to L. Avoid all OTA stuff.

oh wow, huh. Was your bricked in the same way as mine, showing the 'secure booting error' when you try to start it up in any mode? That super good to know. I may just try. thanks for the advice!
Yeah, I will definitely follow your advice and do that, if I ever get it back! I followed a thread I found, but was clearly making a huge mistake. If only I knew that then!

When booting up, my phone did not show the LG and Verizon start up screen. Even the LED wouldn't light up. It vibrated once, so you know it was powered on. The screen was completely dark. When connecting to computer, the normal LGE device showed in Device manager and I could change the COM port to 41 for TOT flash. However, the flash would fail just like yours. The phone model, IMEI were all blank. KDZ errored out too. KDZ is more forgiving in mismatched phone model, and if even it fails, then you probably cannot save it.

Interesting. I appreciate the advice. I'll probably give it a try, since I seem to be out of other options, but I suspect the secure booting error will be a give away that i did something to violate my warranty.

I didn't had the same issue as you, but had a similiar one (phone didn't get discovered neither by LGUP nor LG Flash Tool). Yesterday I fixed it by following this guide:
http://forum.xda-developers.com/showthread.php?t=2785089
In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.
I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

You asked for other people's time to help you, but now you don't have time to explain how you made it work?
Yeah... there MIGHT be other people with the same problem, but why would you care to share.
What an as*hole you are. Another typical new buttuser ruining a great dev community.

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............
oh well
zach
ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(
I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.
Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.
One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).
