Help - Stuck on Download Mode - G3 Q&A, Help & Troubleshooting

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.

follow this, for your variant, it should get you back on track don't forget to check the hashes as a bad download would cause it to fail.

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 tried everything TOT& DLL files KDZ Files no thing work for me.

I have the same problem im stuck in download mode and i cant find the kdz =O

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:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=.../D85510L_00.kdz

how to fix download mode
for all lg phones but if you are not lg user you can contact me for any phone software issues

1. add .com at the end of the link
2. and choose software solution (right side you can see)

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?

i am also having lg g3 F4ooL
installed cloudy g3
soft bricked
boot looping
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] E988 Cant get in Download mode (no custom recovery)

Hello all, I have a problem with my LG oprimus G pro:
I have updated to official 4.4.2 and it was a bit buggy. So I decided to flash CyanogenMod
So the first thing is to root the phone I did that from here
http://forum.xda-developers.com/showthread.php?t=2695263
post #4 guy named galapagos has roottool.kitkat.zip attached. So I downloaded roottool.kitkat.zip unpacked it to "root" folder
folder tree:
--------root
--root.zip
--adb.exe
--AdbWinApi.dll
--AdbWinUsbApi.dll
--StartRoot.bat
and ran the StartRoot.bat that I found inside.
All it did was reboot the phone to stock recovery waited for me to click install from sideload and it than executed next command:
.\adb.exe sideload root.zip
the phone rebooted, and I installed rootchecker app to test if I had root. The test was positive. cool :laugh:
now I wanted to install CyanogenMod I downloaded the latest build from here http://download.cyanogenmod.org/?device=e980&type=
I renamed the file I downloaded to root.zip placed it in the folder where StartRoot.bat is (replacing the old root.zip) and ran StartRoot.bat once again.
the phone verified the root.zip and started to install it. :angel: In the middle of installation it aborted the installation and rebooted the phone. it will not boot to android system (I wonder why ) instead I am greated with LG security error after witch the phone turns itself off.
I have tried getting into download mode buy key combination= hold volume+ and volume - together and connect usb. It only starts charging.
when I press volume down+ home+power it takes me to factory hard reset. but the reset changes nothing...
do you have any ideas how I can unbrick my phone? Will USB jig work on LG phones?
Manually uninstall and reinstall LG drivers. text me if it works for you.

You can try to plug your phone on the PC, go to cmd within adb, key in adb reboot recovery. Voila.

I also have the same problem with my F240S, cann't go to download mode, and can't flash this damn Lollipop kdz
Hello everyone, its been a while, thainks to all for trying to help me
In case anyone is wondering, after I realised I couldnt do anything myself, I gave the phone to phone service.
Acctualy, I gave it to couple of services, some of them didnt know what the problem was, and they were unable to Jtag it.
The others said it was the problem with the emmc chip.
the last service I gave it to (as I understand) tried to flash it with firmware? that isnt made for E988.
Now when I power it on the screen is blank and the button led is changing collers.
I have accsepted the fact that the phone is dead

my problem was solved....actually I tried and retried a few times the same technique...press volume up + volume down and plug in usb cable...finally it worked and I flashed the loliipop kdz...many thanks
yea, i was going to say hold down volume + and plug in usb cable to get into download mode. if that doesn't work, it's a world of headache.
it's not just the phone you should check if youre having problems flashing/rooting/going into download mode, you should also check your computer, do a reboot or try reinstalling your mobile drivers and the apps you are going to use.

T-Mobile G3 BRICKED - HELP!

Hi
I have a t-mobile D851 LG G3, for which i was trying to restore to STOCK software, through one of the guides elsewhere on the forum. My first try FAILED, and now the phone is stuck on the "FIRMWARE UPDATE - Do not unplug the USB connection until the process is finished - USER B51" screen
No matter what i do (all key combinations for recovery mode, download mode), plugging, unplugging the phone, taking the battery out for 30 mins or so, and putting it back - NOTHING is working. It all goes back to the screen mentioned above.
I tried running the LG Flash tool again, but it fails.
Any ideas? Any help would be greatly appreciated. This phone is my daily driver, and I am in a major fix without it.

I wouldn't try any of those files, definitely not for our phone. Would probably do something bad.
When you got errors did the LG flash tool complete with a failed or anything? Just checking because at lease one other poster had errors like that but the flash tool kept going and eventually completed successfully.

[Q] LG G3 without connecting more !!!

Hello friends,
I come across this forum as conceptualized ask for help to solve a problem I'm experiencing with my LG G3. I have a LG G3 D855 asiatica oringe and how much like customizations made ​​some changes, nothing that had not already been done on other devices I've ever had and never had a problem. Once you have downloaded the root Xposed, and some modules framework, using usually came after that, more to my surprise when making a frustrated attempt to install a font that I downloaded from this forum and try to install the app IFont, I realized that the machine began to take much to restart and the worst is that this delay was increasing and even though I desistalado some applications and the source itself, I realized that this delay only increased. Just to give you an idea, the last time I tried to restart took 48 minutes. I tried to go into recovery mode in various ways, in no more managed to get him into recovery. I tried to restore factory settings through and he was not called for more black screen and only the LED flashing blue and red. Please if anyone can help me I earnestly beg you pass me an email: [email protected] or answer right here.
Grateful.
try to get into recovery by powering the phone off. remove and reinsert battery. plug USB lead into USB 2 port on the computer. press and hold the volume up button. keep the button pressed while you plug in the usb lead to the phone. that normally gets in to recovery. (does not always work with a USB 3 port for me).
then flash kdz in "normal mode" using the instructions in another thread. or use the LG more support tool. (sorry, not able to search for the correct threads at the moment, need to log off for a couple of hours...)

Even following the tutorial restoration via KDZ not had success, catering to more starts in less than 2% of a message to retry, or my device is stuck without being able to restore even via KDZ, does anyone here know of one restuara hint how the recovery mode LG G3?
you might want to do a clean reinstall.
Download the KDZ file (V10h or V10j) and try with the CSE flash option in LG flash tool.
boot into download mode (hold power up and insert USB into PC) and then hit CSE flash.
even if the tool says it's done, just wait - do not click Exit. The phone might still do the upload (check the progress on the phone itself).
Be careful about the version of the KDZ file you download - do not use a 16 GB version if you have a 32 GB phone!
Well folks,
I have an LG G3 D855'm having a problem during the restore process via the LGFLASH TOOL, follow the tutorial step by step over when it will begin restoring is no more than 2% and always the error message "retry", has changed the usb cable and the error still persists, you will not have to help me?

an extensive list (albeit not complete) is here http://forum.xda-developers.com/showthread.php?t=2791761
I haven't seen any Brazilian ROMs and I'm not sure if flashing another region would affect 4G reception or not.
Your best bet is to try via the LG PC suite (link with tutorial in my previous post) or get the KDZ for you phoe from LG site:
http://csmg.lgmobile.com:9002/csmg/b...2.jsp?esn=<IMEI HERE>
You just need to replace the red text in the link with your IMEI (it is on the box or invoice).

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

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

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!....

Same here. LGUP Says it is not recognized, even if it says it's a LG G3 855... Trying the LG Mobile Support Tools -> UPGRADE RECOVERY using my Model/serial.
Downloading right now...
Hope it works.
I will tell you when/if I got it to work

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).

i meant LGE mobile usb serial port (com7) and in portable devices its says LGE android MTP device and its has a yellow trangle
so does anything show up when you turn it on? how far does it get in booting? it goes to DL mode everytime? and that's what is in device manager in DL mode?

it boots into dl mode but i cant flash firmware yesterday i recorded it. it boots to lg logo and after 29 seconds it boot to the android guy i did find something in yellow text but it flickers and that says. in short
E: failed to mount /cache (no such file or directory) then can't mount /cache/recovery/log
can't open /cache/recovery/log
and it repeats that text 3 times from what i saw
did you install twrp? i would check your drivers or the cable for the communication failure in dl mode

My goal is to try and install TWRP my phone fully stock I checked everything even my charging port. I'm using the lg cable... My main goals are to get this fixed before March 3 and all I need is an alternative. Get TWRP or return back to stock
at least give me a script to boot to stock android recovery without adb. cause obviously i cant use adb and i hope anybody reading this can remember that with lg flash tool 2014 kdz method it goes to 4 and stops unless you guys find fix to that. all i need is to get this thing fixed before march 3rd. so if you guys help me find any kind of fix this is all i need
here is info but my phone
model: lg-d852 (don't really need it though)
status: stock unrooted device and has never booted into the system
android version: 4.4.2 kitkat
main problem that needs to be fixed: it cant mount cache cause apparently there is no file or directory according to my phone
that's it. if you guys need anymore info about my phone let me know (except imei or serial number cause that's all private stuff) thanks

I used every method
then you must force it into the 9008 mode using the following guide. I would check the dll you are using, drivers, or cable first through. I would be EXTREMELY SUPRISED of a g3 in DL mode that is non-responsive.

i'm surprised that my lg g3 in download mode with the correct dll, tot, kdz. every single program with a fully working charging port and an lg cable is that unresponsive. although at one point the arrows in download mode started spinning an then it stopped and on the monitor it said on lg flash tool (tot method). CAUTION: Primary gpt has invalid value there must be something blocking the connection
oh and my phone is still getting fixed soooooooooo no updates just yet. but like i said if there are no results i'll update you
