Hello, didn't find anything on this thread that may help me. So I'll ask. Bought D855 32gb with 4.4.2 with root from Asia. From the beginning the phone couldn't connect to wcdma /lte, only GSM. Tried to update through LG PC suite. Got error. Then tried flash by kdz method, got error. Then tried tot method, got error. After tot method cannot start the phone, automaticly start up in download mode. Tried hard reset. Doesn't help. What should I do next?
[G3 General] hyelton:
Explain more? What error did you get in the tot and kdz methods?
[G3 General] gdest:
after KDZ see image attached.

After tot, error 00000064 (after 3 seconds after pressing the yellow arrow and unplug/replug phone before Firmware install)
[G3 General] hyelton:
And on the tot method you did change your com port for your phone in device manager to com41? And your using a usb 2.0 port?
[G3 General] gdest:
indeed..usb 2.0 , win 7, changed to com 41.

upgrade dl no success , then tried board dl - no success.

About USB, it's not 3.0 for sure, could it be usb 1.0 or something not 2.0?

It's black socket.
[G3 General] hyelton:
It's most likely not usb 1.0 unless your computer is 15 years old. Each time you try your rebooting the phone right?
[G3 General] gdest:
Yes, I pull out the battery.

Now I only can get to download mode, is it break?

What can you suggest?
[G3 General] hyelton:
Download mode is what you'll want, that's how it's flashed. Now if you see something in device manager about Qualcomm it's a brick.
[G3 General] 4everxda:
Awsome guide. It worked for me, only have one problem. I have the d855 version ( with Poland 21A stock firmware installed and the problem is that I don't have the voice mate and the only option I have when i toggle the pie menu which pops up when you slide up from the home button, is the Google app. Can I use another's country firmware for the d855 or am I stuck with this. If so, can someone recommend a firmware in which these options are present?
[G3 General] hyelton:
Glad it worked for you :). As long as you stick to your model you'll be fine.
[G3 General] imran.khalil:
Flashed stock Lp and then the tool worked just fine.. People misguide a lot .. I read in a post dont get into download mode it will do it itself
[G3 General] hyelton:
That's why you read the OP :) one of the steps is putting the phone into download mode. Glad it worked for you.
[G3 General] javlada:
Never mind, I found a workaround for it. I managed to flash sotck MM first and then downgraded to LP. I don't know why I couldn't flash LP directly over CM13.
[G3 General] heirfister:
finally it worked for me I was able to downgrade to lollipop, thanks to this guide..

I'm using the TOT method to bring my T-Mobile G3 back to stock because it didn't work with the .KDZ method, and it's taking an extremely long time. The FlashTool shows 13% done, and my phone was showing 3%, but then it went black came back on, and is now at 0%. This has been going on for a good 15 minutes now. How long does this process normally take?

---------- Post added at 01:47 AM ---------- Previous post was at 01:39 AM ----------

Well it gave me an error, and now my phone is stuck on Firmware Update screen. Great.
[G3 General] hyelton:
Then reboot the phone back into download mode , use a different USB cable make sure you changed the com port to com41. Its unhelpful to post without the exact error.
[G3 General] jeck77:
OK so I retried the KDZ method and it worked this time. I'm back to the original firmware.

Unroot...

Hi,

I want to root my

LG G3

Model D855

FW: V10i-ISR-XX

Base: KVT49L.A1408602401

If I want to go back to that.. How can I do this? I didn't see my model at the KDZ files list..

1. Can I flash the stock (Any) and from LG PC Suite Change to ISRAEL and Flash the FW? (So back to ISRAEL stock FW as above?)

2. Is there an issue or trails / tracks of root after flash? such as KNOX on Samsung?

** Which root method do you recommend?

Thanks :=)

hello, after this step, its been around two hours and nothings happens

PC shows this:

and my AT&T LG G3 D850 shows Firmware Update, Do not unplug the USB Connection until the process is complete, 0% , User B100

should I move with the next step?

or still waiting? how many hours I have to wait before to proced step 14?

thanks

EDIT I'm tired of waiting, so I move on with the next step, I press and hold power button but the phone doesn't turn off :(, What I should do? remove battery?

EDIT2 I remove the battery, now the procces finally started :D

EDIT 3 FINALLY I recover my phone after bootloop, so happy thanks for the guide
[G3 General] Deagles:
Flashtool giving this error and it doesn't flash anything..

After 1-2 hours phone still waiting at %0
[G3 General] hyelton:
Too everyone who flash and it doesn't work or sit there it doesn't take several hours to flash it only takes a maximum of 30min.
[G3 General] MaEdCo:
yeah, but one step is missing, I discover after wait

12) Click the S/W box and select the firmware file with .tot extension.(the 2.04 gb file from above)

13) Now click the Yellow arrow button on the top left of the main window.

The firmware installation will be triggered.

Ignore if you see any temporary error

13 A

Do not close the Flash Tool window.

, remove the battery, and put it again, ,immediately hold volume up button until phone boots it into Download Mode and now the procces start, the phone will reboot afer a series of commands shows in LG Flash Tool and the screens turn blue , show Fatory reset or something and the number 2, then if its succesful it will show number 3 on the phone and PASS on LG Flash Tool, unplug the usb cable from computer, hold power button, reboot and enjoy

just one question, why right now I can't install nothing from playstore? every app that I want (e.g. whatsapp, dropbox, poweramp) shows that is not compatible with my device :(
[G3 General] Deagles:
I know i did it before but now somehow it doesn't work and i can't flash the rom.

İs there another way to flash rom ? it seems i'll be without my phone a few days
[G3 General] hyelton:
Reboot PC? Use different USB cable?/uninstall everything and reinstall it back?

No this is the ONLY way as it has ever been for LG phones..

There's nothing missing from the guide. Also try restarting your phone? Did you perform a factory reset after flashing?
[G3 General] MaEdCo:
yep it is, but i dont wanna discuss

thanks, I forgot this, now is working :good:
[G3 General] Deagles:
I have only one cable uninstalled everything and tried again but none of this works i don't know what's the wrong man i just got bootloop so i wanted to flash kdz but this time phone stucks in the fw update mode and not getting the fw

There might be a problem with the flashtool can you check it out again because it gives the "connection to server fail" and canceling the flashing which i don't see in the instruction videos before.

I tried the tot method after the kdz method doesn't work for me but it's not flashing the fw and it says different model number. İ tried the non-brand Eu tod with my d855tr device because there is no d855tr tot file and it just didn't work.

I think ı'm going to sent it to service for this simple software problem.
[G3 General] JDinAZ74:
I managed to get it working finally after reading a few more threads about returning to stock. I don't mean to sound derogatory but your guide is a bit vague in a few areas. For me holding the power button did not reboot my phone a battery pull was necessary also maybe explaining a bit more in detail about how to put your computer to com 41 would help those like myself that are doing this for first time & not familiar with flashing a LG phone. Also I could not successfully flash my phone until I checked board DL check box instead of upgrade DL in manual config. Overall this guide was helpful & I appreciate you taking the time to help others and for providing the files needed to do so. Thank you.
[G3 General] bigmantuck:

T-Mobile D851

There are a bunch of files in the D851 section.. which one do I need to download?
[G3 General] Dionisis89:
Yes, yes and yes. Well, actually, the Flash Tool keeps quitting on me after I "select language" (where it's mentioned to leave it as it is, Korean), just after a second that it starts. I don't know what's the issue, and I'll elaborate. I had used this method a few times a month ago and it worked perfectly (KDZ method). Now I wanted to revert to stock and this issue happened on the same PC that I used the previous times for this procedure.

Just wanted to say thanks. Just used LG UP to upgrade my rooted 5.0 D855 (v20i I think) G3 to Marshmallow using the instructions here and a kdz from the marshmallow discussion thread. Took me a little figuring out as I just rooted it before and didn't do much with it other than install TWRP, was mainly doing it for SDFix, but your guide was very helpful and for the most part friendly for a newbie like me.

Thanks for the help :)

Try the tot method? And be sure it's usb 2.0
[G3 General] hyelton:
Why not update with flash tool?? Your using a usb 2.0 port right?
[G3 General] MAT_lal:
I find LG UP easier because of the one step only installation, and i tried both 2.0 and 3.0 usb. I did once flashed via LG UP and it was fine, but i was before i sent it to LG for repair, and they changed my motherboard, I don't know if it could be caused by that. Now my phone is almost stock, just rooted via Kingroot. No custom recovery no custom rom. Previously i flashed from CM to LG rom.
[G3 General] hyelton:
Flash tool is extremely easy. Usb 3.0 absolutely won't work it causes issues.

You using the cable that came with the phone? That can also cause issues. I'm not sure on the errors on LGUP as I've never ran into any.

Power off the device, hold volume down and power. Wait for lg logo to appear, shortly release the keys and then press and keep holding the keys again. Select Yes to the 2 questions asked as soon the white board appears. It will wipe all the data and reboot

[G3 General] ncjones28:
My phone will not go into the firmware update mode. Also i am on windows 10 and my device manager does not have the 'Ports' area. Would the phone show up somewhere else?
[G3 General] hyelton:
The ports will show up under ports in device manager. Since you have Windows 10 you must unhide them. But first before you can do anything you must have the phone in download mode.
[G3 General] ncjones28:
Thanks, I unhid the ports. My issue is that my screen never shows the firmware screen. Last night i tried to flash Jasmine ROM 9.0 and it caused my screen to not work. So I do not know if it is actually going and i cant see it or if it is never getting into the firmware screen
[G3 General] hyelton:
What screen does it show? If your phone has no power what so ever it's bricked. So your pulling the battery, put it back in, holding vol up or down while plugging in the cable which is connected to a usb 2.0 port?
[G3 General] ncjones28:
It shows absolutely nothing. I can only feel it vibrate, so I really have no idea if it is ever getting to the firmware screen
[G3 General] hyelton:
Did you try what I said though? Now if your phone keeps vibrating it's dead.
[G3 General] ncjones28:
Oh yes I did. I tried holding up and down (separate) the phone just vibrates until I guess it boots up (it makes a noise) but there is nothing on the screen. So its getting power, but there is just nothing on the screen. Thanks for the help by the way.
[G3 General] mistice34:

[G3 General] rajahakabalbab:

I am getting error after 2% i got an error mentioning upgrade stopped due to an error what to do

lg flashtool 2014
[G3 General] hyelton:
Phone in download mode?? Using usb2.0??

If so then you'll need to use the tot method.
[G3 General] Dionisis89:
I tried that, too, but upon starting, the flash tool stops the process saying that the "Device model is different". Not sure what's up. The .tot file I'm using is for the D852, as well as the .dll .
[G3 General] hyelton:
That is because the software currently on your phone is not D852. You'll need to edit your d852 tot with an hex editor to edit the tot to whatever model software you have running on your phone.
[G3 General] Dionisis89:
I used HxD to replace all instances of d852 with d855, but now it fails without even starting, the error that pops up is "Failed PreviousLoad()"

Maybe I should edit the .tot file's name as well? And the .dll's, too?

---------- Post added at 04:05 PM ---------- Previous post was at 03:52 PM ----------

And another thing. In order to fix that LGFLashTool crashing issue, I opened CCleaner and fixed the registries, so it wasn't crashing any more. However, it won't find my device in download mode so it makes no progress. Why so? Using the same drivers as 2 months ago and exactly the same configuration, everything had worked just fine. What may be the cause of it not working now?
[G3 General] hyelton:
And each time your freshly putting the phone in download mode? Each time it "fails" you need to reboot the phone. And not sure if you awnsered my question but you sure your using usb 2.0? Usb 3.0 will cause issues and not work.

And with the tot method did you try the LGUP .dll file?? And try board_dl on the tot selection screen?
[G3 General] Dionisis89:
Yes, of course I'm rebooting it each time. And I'm always using USB 2.0.

Wait a second....the rom I'm using is a port from the official release of 6.0 from D855 for the D852. So can I use LGUP to revert to stock, seeing it's D855 only?
[G3 General] hyelton:
You can try. But it may say mode unknown and not work
[G3 General] Dionisis89:
I'll give it a shot. EDIT: It failed, says "Model unknown" as you said.

Regarding what you mentioned above, where is that LGUP .dll file? And where can I download the board_dl to choose it on the .tot selection screen?
[G3 General] kalpesh patil:
dll

go here http://www.androidbrick.com/download/lgup_8974-dll/#

hit thanks if i helped u
[G3 General] Dionisis89:
I found a "workaround", so to speak. Since the TOT method found issues because it identified the device as D855 and wouldn't load the corresponding files to avoid bricking, I simply flashed another D852 stock based rom (Fulmics) and then tried the TOT method and it worked flawlessly.

Thank you very much for your patience! :)

Trying to return to stock and having an issue, to give background, Up until a few hours ago I was running on a stock rooted 4.4.2 (verizon 10b I believe) that obviously couldn't get updates, so I did a factory reset on it from the volume down/power button menu, this allowed me to get several updates, including but not limited to the android 5.0.1 and android 5.1.1 updates but when trying to install the android 6.0 update it would error out at like 3% and eventually reboot, so I decided to try to restore to stock since all this time it still shows "software status" as "modified", I have downloaded and configured everything with the exception of a USB 2.0 port as my computer ONLY HAS 3.0 ports (G750JM-DS71) using the TOT method and every time I try I get this failure within a few seconds of reconnecting the usb to get the transfer started. where should I go from here?

[G3 General] kaijai_tm:
Hi. I'm hoping that someone can advise me what to do.

My LG G3's intial SW was LG855AT-00-V10n-Global...(4.2.2 Kitkat)

I rooted and attempted to install twrp custom recovery and messed up the process somehow.

I ended up being stuck in fastboot when I tried a factory reset but a battery pull got me out of that.

I put the phone in download mode in order to flash it using the .tot method but was getting an error all the time and was stuck for hours.

I was ultimately able to get the phone to boot by using LG855AT-00-EUR...tot (4.2.2 KitKat) and a dll (LGUP8974) extracted from D85521A_00.Kdz (5.0 Lollipop) but had to deal with being stuck in factory 2 reset mode and mini os 3.1 before I got the phone to boot. I attempted to use the LGFlashV160.dll, changed upgrade DL to Board DL in flashing the phone before I got the phone to boot.

Sidenote - I got the D85521A_00 file from lg-firmwarerom.com after using my IMEI number to get the associated stock firmware for that IMEI.

After the phone booted, I saw a **** TON of bloatware on my phone additionally to the radio not working (i.e. It can't connect to the network. Can't make or receive calls). I assume this bloatware is because of the EUR firmware.

I then used the KDZ method to flash D85521A_00 to my phone using the CDMA, DIAG and CSE Flash option to wipe the phone. There is still a ****load of bloatware and radio still doesn't work. SW is now V21A_Global_YT.

Sidenote - I have a friend with V21A-AME-XX. (not sure if that's an important point)

My Model Number is now LG-D855RE instead of LG-855 and my IMEI is now all zeros. I'm on Lollipop 5.0 currently.

I provided as much information about the situation as I could. Does anyone know how I can get the model number back to just LG-D855 and my IMEI to be not all zeros? I'm thinking either one or both of these reasons is/are why I can't make calls.

Your help would be greatly appreciated.

Problem with unrooting

Hi guys. I have a problem with my LG G3 D855. I have the KDZ file of the MM update, but when I try to unroot the device with LG Flashtool, the COM port is not written on the phone, the progress bar on the phone won't progress and when I reach 10% on the LG Flashtool, it said me "Connection to server failed" And I can only click "Retry".

I'm trying to update an L400K to the latest v30B kdz and the process fails every time.

I think it has to do with my drivers as it fails to properly install 2 out of the 4 drivers associated with my phone every time.

I'd like to try the TOT method but am unable to find a v30b TOT file.

Does anyone know if there is either something special that needs to be done with the drivers for the F400K (I've tried 4 different versions now) of if the TOT exists for v30B?

Thanks for any help!
