unrooting problems-xda

i have lg g3 f400. when i unrooted my phone it was on version v11a and it downgraded to v10a and after that mcafee security key problems started. first it asked me the key to open the device which i didnt have because of used mobile. after that i searched and got a solution that opened the mobile but rooted again because of mcafee and according to it delete the mcafee software so i just deleted it and then its download mode and emergency mode were disabled by kill switch. then i installed bump recovery into it and by mistake flashed a wrong file which make my mobile soft bricked. now i am locked from all ways to start my mobile again.

kindly see into it and come for some solutions so that people like me who had purchased this mobile with huge amount of money will get out of this problem without the fear of losing their problems. thankyou xda team

[G3 General] DKOMofo:
I have bricked my phone this morning trying to install TWRP on my phone after rooting it. Well it didn't work out and now I'm just trying to get back to normal. I've tried the TOT method several times and followed the instructions to a T.. Every time I start the process it gets stuck at 10% on Modem. I have no idea what's going on or how to get it to pass this. I am just trying to get my phone back to stock. Any and all help is greatly appreciated.

Hi I tried the kdz method i did every step when I click start it doesn't do any thing when I tried the tot method I can't find my phones DLL file help ?

You have to download the DLL file along with the TOT file.

Fixed the issue yesterday. He was using a bad USB cable.
[G3 General] bender_007:
Whoa..I have to say I had also a "bad cable day"

Recently I killed my g3 and had to open it, short wire and it didn't work. I changed to another cable and boom.

So sometimes it's so simple "cable" :)

I'm glad it's fixed

May I recommend you to link in first post:

for example: if you can't enter download mode -> and here you are linking some other threads, let's say fix for fastboot mode, fix for qhusb9008 etc.

Hanging by a thread

[MENTION=2607037]hyelton[/MENTION], Hey bro, I apologize for bugging you again. Whenever I connect my phone to the pc during the "firmware update" screen, It shuts down as soon I run Lg flash tool especially when it tries to determine theres a usb connection to my phone. Sometimes the usb connection shows up, other times the port connection shows up. But neither of them shows up together on device manager at any given time. What could be the issue? And is there any other way to breathe life into my phone without using a usb connection to my pc, anything really? Maybe rooting it somehow? I dont mind how tedious the process might be Im in it for the long haul.
[G3 General] hyelton:
You need to use USB, so if theres something wrong with the USB port on your phone nothing can be done. But make sure your using the cable that came with your phone and using a USB 2.0 port. USB 3.0 wont work.
[G3 General] sydeu:
This worked very good, but now when my phone starts there is some mcafee security pin code, i have no idea what this is about and have never used it. Not sure how to proceed.

edit: I managed to solve it by contacting the previous owner and got the pin code, apparently he had used McAfee. What's funny is that I have had the phone and used it for 4 months on different custom roms and to begin with stock and never had any problems. But when i flashed to stock via kdz from download mode it came up and wouldn't allow me to use the phone or do anything.

Don't touch the message!

If you touch it before flashing ends you might brick the device

-ignore the server connection message

-don't press "read phone information"

Hey [MENTION=2607037]hyelton[/MENTION] i have a lg g3 d855 with a vodafone branding.. Do i need a special tot file for it or are all tots the same for d855? I know i can flash kdz, i also did before but it didnt restored fully to stock... I man before when i bought it there was a vodafone boot branding and some apps.. I really want it 100 as stock as the beginning, what i heard was that tot files would do that..

In 2015 method, I can see 5 files in the step "1.1) Download Both Stock Image & DLL File":

D85110C_00.7z

D85110M_00.7z

D85110R_00.kdz

LGD851AT-01-V10c.zip

LGD851_20140611_LGFLASHv160.dll

dll file is the last one, but for the stock, I only need to download LGD851AT-01-V10c.zip right? I am confused because in 2014's method we were using the kdz file but here we're not.

And please also tell if this is KitKat or Lollipop? I have a lollipop rom and it has restarting issue. Even lollipop based CloudyG3 has the restarting issue in my device.
[G3 General] usman farhat:
Thank you! it flashed correctly, but I have a suggestion.

Please make a line in first post more descriptive by changing " 14. You may need to unplug/replug phone before Firmware install will start (If it does nothing after clicking the yellow button"

to

" 14. You may need to unplug/replug phone before Firmware install will start (If it does nothing after clicking the yellow button i.e it shows a dialog showing some words like reading this that etc. but then the dialog disappears and no progress bar appears in the pc software.)"

I'd suggest you go back and re-read the OP.. The D85110R_00.kdz is the KDZ file...You even pasted the file name above ^^. The rest are TOT files. and in which if you wanted to do that you'd follow the TOT method which is below the KDZ method. There's 2 methods in the OP.
[G3 General] hyelton:
Whatever corresponds to your model #

And did you try board_ID on the TOT/DLL selection screen?

Hey guys.

Searching the thread for 30 minutes but couldn't find a post to see if flashing a stock KDZ also means locking the bootloader or not.

Asking this because I'm about to send my phone to the LG service and don't want to lose warranty as I'm currently on a custom ROM.

Thanks in advance :)

Take off the back of the phone and read the number on top of the flash

If it says d855 it's international

[G3 General] ghylander:
If it says d855 there and under "hardware info" in settings, I would say most probably European, as the Korean model number is f400

You should wait a bit and see if someone else replies though, I'm not completely sure on your case
[G3 General] bishop__x26:
bro please watch this video.... my lg g3 fades into darkness i dont know whts wrong thats why i wanna set the 4.4.4 version to see if the problem dissappears.... do u have any idea whats the problem of this ?

[G3 General] ghylander:
Well I don't really know what could be causing such problem

Seems like you are not alone though,there were some more videos with people with similar issues

I don't personally think that flashing 4.4.4 or 5.0 would make a difference in solving the issue

System software gets replaced on both cases so whatever the problem was it will be overwritten

You are free to flash 4.4.4 and 5.0 later at any time though

I'm having a similar issue but my phone will start the process and then it disconnects and shuts off and then the device changes to a Qualcomm HS-USB QDLoader 9008.

Same problem here. Phone appears to be bricked at this point. Using the hardware buttons to attempt a Factory Reset just brings me back to the Firmware Update screen.

Any ideas???

---------- Post added at 02:45 PM ---------- Previous post was at 02:11 PM ----------

Nevermind... fixed it by switching to a USB 2.0 port. I didn't initially think I could use that port because it wouldn't come up in the Device Manager step under Ports... so I tried on a USB 3.0 port and the Device Manager step worked fine. So if you guys had a similar problem, try again on the USB 2.0 port and it may work for you as it did for me.

I'm from Malaysia and before I root my G3, I rmb it being a TWN version. So I was looking for the TWN version from storagecow site and I only found one TWN version but the file is under 'D855 TOTs'. Does this mean that I have to use the TOTs way of going back to stock or I can still use KDZ way?
[G3 General] Gil81:
Has anybody used the flashtool from this thread with the supplied mega dll file and had success..recently? Im trying to see if its the tool itself or my ancient windows xp, that is causing the tool not to see the dll file and ask for a login and password.

Thanks
[G3 General] hyelton:
Yeah using USB 3.0 wont work at all for this you must use USB 2.0 ports.
[G3 General] hyelton:
Its failing because your not using a USB 2.0 port, OR its because your not in download mode. You MUST be in download mode for this to work.
[G3 General] hyelton:
Yes. There's no issue with the tool. What does your flashtool folder look like? Are you replacing the megalock.dll file thats currently in flashtool folder after installing it? or is it adding one? If its not replacing it theres the problem.

And your using this exact file correct? http://oceanhost.eu/o9n2mef5f2no/MegaLock.dll.html

[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Me. I just replied stating that with the G3 it doesn't matter unlike the G2 was. I'm the one who owns that site ^^ so I'd think I would know before putting them there :)
[G3 General] user28:
Thank you. Since you confirmed i will use them for my 32 GB india version. But what do you mean by "with the G3 it doesn't matter unlike the G2 was" ?

Also i want to get clarification on three things:

1) What is the stable version of Kitkat accepted by all? Atleast with less bugs and less heating problem atleast..

2) If i root the device and flash the TWRP recovery and then later on if i flash any KDZ file, i knew i will lost the root but on the recovery part I am not sure. Will I lose the recovery also and the phone will be on stock recovery once the KDZ is flashed?

3) My device is heating more than normal. Just after watching a 2 minute normal (not HD) video in whatsapp, my device felt warm. God will know how much hot it will be if i play a game like Real racing or other heavy games.....:(

I saw various threads to solve this heating problem but i found this one to be least risky.... at least in my opinion.

http://xdaforums.com/lg-g...e-gov-t3047490

Whats your opinion on this?

Right now i am on V10F Kitkat (India).
[G3 General] hyelton:
1. To me there all the same, so no clue don't currently have a G3.

2. Yes if you root/TWRP and flash a kdz you will loose it again and be back stock.

3. Whenever I had my G3 it was always hot but it never caused an issue. Besides the bugs I had with the D850 lol.
[G3 General] user28:
Thank you. One last question.

How to fix the external sd card permission issue in Kitkat? Root and use the SDfix app from playstore?
[G3 General] Gil81:
Yep..I'm replacing the file and am using that DLL file. I believe the problem is with Xp. I'm going to run all its updates and GI e it another go. Thanks for the response. I'm sure I'll get it up and working.
[G3 General] hyelton:
Its not an issue with XP itself, but could be an issue of what is installed. It works fine on XP if anything XP/ 7 are the best to do this on.

EDIT: That issue has been fixed, but now I get the following when I do the things in LGFlashTool:

Something on your other computer could be causing the issue. Also usually that error occurs when there's something else using com41 or using a USB 3.0 port.
