OK, my problem was Windows 8.1... The phone is well recognized by LG Tool under W7, but now I have another major problem, at the last step, when the tool begins to flash the rom, it goes until 5% and then this popup box blocks the flash "battery level is low and upgrade is unavailable"
I have reload fully my battery (I plugged it into the G PRO dock)... still the same message.
Any help please ?

Did you manage to resolve the issue? I am just having the very same problem and a bit lost and cannot risk flashing anything right now.

Hello, I would appreciate your help because I flinched and my tel ugly now this only in the LG logo screen. I wanted to update my original rom Phone factory and downloaded the latest version before upgrading but I did not wipe data and When there finished the process gave an LG IMS error stopped working this type, and there Could not get into hard reset on the way, OK up here but then I Decided to reinstall the rom again to see if it would correct the error and then I installed the previous version I had downloaded it and my phone is so in the logo screen. If I try to instal the updated rom, would be more risk? And I wonder if I can not like the ace debugging would access via adb and make wipe data factory reset only by simple USB connection? I can not I do the code by turning the volume down and holding power button goes not into hard reset the screen goes black and comes back on the LG logo... Pleaseeeeee help meee!!!!!!

[Q] Bootloop, and factory reset is stuck [SOLVED]

My device is rooted with towelroot, I installed supersu afterwards...
before bootloop I installed fontexplorer, and installed few fonts, it asked me to reboot, i rebooted, and now it just bootloop's all the time, LG animation and vibration, I can't get into fastmode, tried all kinds of button combinations..
When I try to factory reset, after pressing yes it shows erasing, and then it's stuck on boot logo, not animation..
Download mode is stuck also, just shows 0% but at least then pc's device manager shows com device found
How to fix this ?
All this happened after I rebooted my phone, before rebooting I installed few fonts with Font Installer ★ Root ★(com.jrummy.font.installer) app

THIS guide will help, you've softbricked, only in this guide you will of course need the dll and tot files for your phone and not Sprint. As long as phone comes on,computer recognizes it, and, it goes into dl mode, you should be good.

That stinks huh?!
I've been using iFont and Fontster from the Play Store without any issues for future reference.

G3s to me are finicky about changing or modifying. I modified one build prop setting, rebooted, same thing as op, mine wasn't bootlooping tho, but stuck on the big red 2 screen. Flashtool is your only friend at this point.

Wow, I can't believe I fixed it, I thought it's impossible
I just went into download mode and used LG Flash Tool 2014 to flash to stock firmware..

I think I read back when I was unbricking that .KDZ files have to be converted to .tot, to use with this version of Flashtool.

Quick Question
Hey guys,
I am a bit of a rookie with rooting and i have an LG G3 for tmobile. I rooted my phone and had TWRP installed and accidentally attempted to install a software update and it soft bricked my phone. Here is my problem-all of the solutions i am finding for this issue require a PC, and I, unfortunately, am only running on mac software. I have no way to get lg flash on my mac and to make it comparable with my phone. Is there ANYONE who can help me? I am at my wits end and CANNOT believe I was so stupid as not to make a backup flash but I, as per usual, did not think about it at the time. If anyone could help me, I will be forever in your debt.

I believe you can run virtual Windows on a Mac, not sure if it works with Flashtool though.

Unable to boot my rooted LG G3 S (beat), stuck at lg logo.
hello everyone. I recently rooted my lg g3 s (beat) D722K. After a few weeks I was trying to install apps as system apps using ES file explorer for which I had to copy the desired apk in the system/apps directory and restart the phone. it worked for a few apps (which I successfully made sys. apps) but not for a majority of apps . Everything was fine until now . After that I wanted to normally install an apk but the phone was unable to install it showing ' application not installed' . Then I tried to install other apps but got the same result . I decided to reboot my phone but it got stuck on lg logo and won't boot .
I tried to factory reset it using hardware keys but after wiping all the phone data it again got stuck on the same sucking LG logo .
I also tried to update firmware by connecting it to windows(8.1) pc in download mode which didn't work either. The firmware download got stuck at 0% everytime I tried.
please help me in getting out of this issue . I will heartily appreciate any help regarding this issue.
thanks.. in advance.

LG G3 Stuck in bootloop after Flashing Stock Rom

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!

I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

Random Reboots and Bootloops

I flashed 30c firmware with flashtool 2014 over rooted 21a (i think) on my D855 from Greece. I selected the normal flash to keep my files and apps, phone mode: DIAG and didn't clear the update registry. Phone worked normal for a week and then went into a boot loop. The phone randomly restarts and goes into loops for a while and then snaps out of it.
I have tried the following and none have fixed the issue:
-Replaced the battery.
-Upgraded to 30f over lg pc suite hoping it would fix it but it didn't.
-Flashed 30c and 30f over LG Flash tool with CS_EMERGENCY mode and cleared the updated registry.
-LG Flash tool wont flash any older lollipop kdz I tried. The phone screen flashes once but stays at 0% and then I receive a phone disconnected message.
-Put the device into safe mode and used the option on lg pc suite to fix upgrade errors. Didn't fix anything lol
-Tried factory reset. Nothing happened after I selected the yes on the confirmation.
-Tried to use LGUP hoping to install a lollipop kdz but it gives me an error message that I have to select a known model. Restarting the app and the phone didn't work either.
-Tried a guide on how to unroot and return to stock with the kitkat .tot file .
I really have no idea what else to try. Any help would be greatly appreciated.

Replace the battery

I have the same problem and i got into the problem for the same reason.... the random rebooting that everyone says is down to the battery is something more sinister... i have tried 4 different batterys that work perfectly and it still happened i flashed a kdz and now i have a bootloop and no OS none of the other kdz files work neither do the tot files and lgup doesnt recognise my device... stuck...

That's the first thing I tried on my list of failed attempts to fix the problem as you can see... Brand new battery. No change.
DjCaprio tried 4 different batteries as you can see.
This is just terrible!

I tried removing the battery while connected to the pc via usb already. The other trick that involves editing a file requires root.
My phone started flashing the blue screen of death today so I finally took it to LG so they can check it out. Either way thanks for trying to help.

LG G4 Stuck In Firmware Update - Stock Reset?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.

Did you have LG up set at refurbish or upgrade.....

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%

Have you made sure that it is the right region......
Try to down load just tot file and try that....
