Pc difference flashtool! Experienced reply

I stayed up for hours on this Windows 10 machine to no avail. And then I used someone else's and it works. Same type of USB ports and same version of Windows and same drivers. One had issue and one worked (no anti malware blocking). Any theories?

Thanx

I cannot rest still after achieving finally unbricking two devices with G2 LG Flashtool and G4 with LGUP.

:rolleyes::confused::(:o

First I would like to say thanks for the original post.

Second when I try to run the program and flash my Aristo 2 After it tries to analyze the phone settings. it will fail on me saying connect to server failed. It asks me if I want to cancel the LG Mobile phone S/W upgrade. I have the drivers installed. I just don't get what I'm missing or doing wrong.

I was able to flash the latest firmware with LG bridge.

Just flashed stock ROM.

I was running with multiple errors of my LG G3 mobile. Then found LG Flash tool and flashed the stock ROM. Now all the matters have completely wiped away. Thanks, XDA developers.
[G2 Android Development] dharakv:
Same situation here. Unfortunately none of my SALT backups are working so I'm thinking of resorting to LG FLASH TOOL. in Normal mode to preserve my data. Just one question though.. did you select the Type as CDMA, and prior to pressing the Start button, did you click "Read Phone Information" ?

Thanks
[G2 Android Development] cacingbesar:
God bless your soul, OP

I revived my semi-bricked phone!
[G2 Android Development] dharakv:
Thank you so much LG FLASH TOOL 2014. Because of this wonderful tool, I was able to recover from a softbrick which occurred through build.prop changes, while preserving my data. I had no custom recovery, and my photos, videos, etc was still on the phone. A Normal flash did the job. I now have access to all my apps and data, just as I did prior to the softbrick.

Two things I noticed was, never click the "Read Phone Information" option. It will freeze and crash the LG FLASH TOOL 2014 program. You can test the connection to the phone using Send_Command.exe or ADB. If they detect the phone, then LG FLASH TOOL 2014 will also recognize it. Once the program recognizes your phone, just proceed to the flash. Throughout the flash, I got the message "Connection to the server failed". Regardless, the Download Mode progress bar was moving so I knew it was flashing. If you get the connection failed message, don't close it, just let the flash continue until you see 100% in Download mode.

So overall, it was very good. I highly recommend this wonderful piece of software

Thanks LG FLASH TOOL and huge thanks to XDA-Developers! :) :good:

[G2 Android Development] Micromantic:
My L9 is stuck at LG boot screen, I can only access Download Mode. I'm trying to go back to a stock kdz after using Cyanogen for some years.

When I'm on the 3rd step of the process, the phone shuts down at 15% and Flash Tool says that my phone is disconnected. The phone just goes black, it doesn't restart. After waiting for a couple of minutes, Flash Tool says it needs to restart. Then I can unplug and reenter download mode, but it happens all over again.

Could someone please explain what "Select Country & Language" actually does? Are there any consequences to selecting a country different from the "original" country on my phone? Similarly, does selecting a specific language set your firmware to that language (like in build.prop or something)?

I have an LG Optimus L3'ii E425F and using the guide at https://lg-firmwares.com/downloads-file/683/V10J_00 has bricked this device. I used LG Flash Tool 2014 to download the stock firmware but the LG mobile Support Tool shows "Do you wish to cancel the LG mobile phone s/w upgrade?

Connection to server failed. Try again in a moment."

Now the phone is stuck in download mode foreever.

I tried using LGFlashTool_2.0.1.6-ieatacid, after extracting the DZ file and the DLL but nothing happens.

I tried using LGUP 1_16_0_3 with uppercut but neither recognises the phone probably because the phone has a MSM7225A processor where as LGUP only supports 8*** series CPU.

Any ideas thanks!
[G2 Android Development] vtdone:
LG Optimus L3'ii E425F stuck in download mode solved

Nevermind, I solved my own problem. If yours is stuck in download mode, simply head over to LG and download the LG Mobile support tool. Install the LG USB driver, then that one.

Run the LG mobile support tool

Put the phone in download mode and connect to the computer via usb

Let the LG mobile support tool detect the type of phone whether there is any update to the rom.

Let it download the latest update

done - phone unbricked and runs the latest rom

And as a bonus, it's now unlocked properly whereas before this, it would not connect the SIM it was supposed to be unlocked for!

How to Install/Flash a KDZ Firmware on LG Devices

nerdschalk.com

Very easy to install kdz on Lg Optimus L90
[G2 Android Development] pi77:
Hi, I have an LG G3 that can be the download mode (vol-UP + plug into

PC USB port), but neither lg flash tool nor LGUP worked. Before this, it

boot into fastboot mode and I must have flashed it the wrong images.

Lg flash tool came up fine and could read the phone parameters fine,

but seemed to just sit there after I hit "START", no language dialog

popping up to continue with download the KDZ file. I tried both NORMAL

and CSE flash.

I tried installing different versions of lg flash tool and lg driver. Phone

on firmware upgrade screen, tool recoginized phone and could read its

states, not nothing else happens.

LGUP also came up and recognized the connection, but showed unknown

model and refused to go further. Uppercut didn't help, same problem.

I am out of idea. Could someone help?

Thanks!

P.S. My phone model is LG-D855. I am using a Dell laptop running windows 10.
[G2 Android Development] Anghirrim:
Hi, I don't know if it applies here, but you may have to download and add into your working folder a .dll dedicated to your phone.

We used to have it for the LG G4c, without that .dll, the model would stay as " unknown".

Maybe check on Internet for "LG G3 dll lgup".
[G2 Android Development] pi77:
Thank you so much Anghirrim. I will give it a try and report back.
[G2 Android Development] pi77:
Hi Anghirrim, I got the LGUP_8974.dll from LGUP_LG_G3.zip, but lgup tool still showed unknown model and didn't proceed. Is there a tool that could just forcebly flash with the download mode?

Looks like my phone is on the upgrade firmware screen ready to accept a download.

Background: When my phone was originally in the fastboot mode, I might have flashed the wrong .img files and I didn't flash the modem.img file along with other .img file either, so now I don't know which state my phone is in.

Thanks!
[G2 Android Development] Anghirrim:
If your LG up still shows "unknown", check your drivers, your usb cable and also make sure that you ran the .bat that comes bundled with your LGUP_LG_G3.zip file.
[G2 Android Development] Anghirrim:
We're talking about LG Up here right? Because you're in LG flash tool thread.
[G2 Android Development] pi77:
Yes, it's LGUP that I tried with the D855 DLL as you suggested, but it didn't work.

I only mentioned LG flash tool because that I think that's how I bricked my phone

in the first place.
[G2 Android Development] pi77:
I tried .bat, drivers, different versions, different cables, nothing worked.

I don't think it's the cable, because the tool(s) recognized the COM port fine.

If only LGUP has an option to just let me flash regardless or let me set the

model number.

Here is what I did from the very beginning

1/ Phone originally could boot into flashboot mode

2/ fastboot flash boot boot.img

fastboot flash aboot aboot.img

fastboot flash recovery recovery.img

fastboot flash laf laf.img

but I did not flash modem.img, thinking it's the same.

These img files were from Europe D855 kdz

3/ Could boot only to download mode (because laf.ig was flashed)

4/ When I boot the phone all the way up, it's like a factory reset, except

that I could not init the phone, likely due to the modem.img I did not flash.

So I could not get to "Settings"

This is where I am.

[G2 Android Development] Anghirrim:
Well, then I'm running short of idea sorry...
[G2 Android Development] pi77:
Thank you very much for your effort, Anghirrim. Appreciate it.

What is the right dll file for the LG Wine Smart H410?

The Flash Tool 2014 won't work, 'cause i got this first:

So i opened "Tools" and installed it. It said, that this it was successfully installed. But i get this message over and over again, when i choose CSE Flash. I "installed" it a thousand times, but it never really installed it.

I downloaded the "B2C Client" on my own, but the installation stucked after seconds (there are many people who had the same problem).

I hoped, that the patched 2016 Flash Tool would solve my problem, but there i have to choose a dll file... it only had something like MegaLock and Zephyr. I can't find the right dll for the H410 device.

Finally i can't use the 2014 FT and the 2016 FT.

Any hints for me? I had to delete the FRP on this unit, 'cause this was my mothers phone (she died in August 2022) and i can't find her google account information. So i thought, that i can reset it completely with a new Stock Rom flashing.

Any help would be appreciated.

Thanks.

In case you still need a solution (or someone else who runs across this), I've found one. It seems to be an issue with Windows 10 or newer OS's. I created a Windows 7 virtual machine and it worked the first time. So you'll need access to either a physical computer or VM that's running Windows 7.
