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] LG e975 won't boot, stuck on logo of LG

My new phone had been arived a few days ago, i want to install cyanogenmod 11 (kitkat) on my phone, so i installed the nightly buil.d
After that i found a big problem, the phone doesn't detect my sim card (european card), so i have flashed my phone back to stock. That is where the big problem started, the phone won't fully boot anymore. It stucks on te animated LG logo, it doesn't go further.
I tried to solve this by reboot, reflash with original LG software (not a KDZ file as in the first try), but all doesn't work.
The problem still occur.
Can anyone help me to solve this problem?
Your sincereley,

13.Q: I tried custom roms, now I want to go back to stock. How do I do that?
A: Use kdz updater. HERE (http://forum.xda-developers.com/showpost.php?p=44874388&postcount=36) is how to use it. I made simple. Original thread HERE (http://forum.xda-developers.com/showthread.php?t=2010624). IMPORTANT : IF YOU GET STUCK AT LG LOGO AFTER USING KDZ UPDATER,YOU NEED TO PERFORM A HARD RESET. After this,the phone will boot.
Hope this helps

this here is very common that ppl don't wipe and hard reset their phones after flashing stock rom comming from a custom rom, even i forgot that the first couple of times :victory:

[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.

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.

Why so serious, use bootcamp and install windows 7 directly, and come into my debt.

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.

Hello everyone, I am running Lollipop on my Spring LG G3 and I am having a problem.
Recently I went to factory reset my phone, so I unrooted using SuperSu and proceeded to do so from settings and I ended up getting boot secure error. I tried to root using several scripts, manually go to download mode and it never continues, but stays on Firmware upgrade page.
I feel like I don't have a recovery? What should I do in this situation?

guess there r not to many options, flash to stock.

You could try download mode and aw did it actually works my looking up the LG Flash Tool 2014 and using that to install a clean, stock KDZ firmware for your phone. If that doesn't work, then the problem would be deeper.

I hope somebody can help me.

I have a LG G3 D855 with the marshmallow KDZ flashed with flash tool everything was good and had no problems. Two weeks ago i rooted my phone and the next day i wanted to install Xposed and after searching for a bit i installed it and got stuck in the bootloop. I managed to recover it by using the .tot method and since then my phone is messed up, like when im using it it restart for no reason at all, or just when it restarts i unlock it and 6/10 times it restarts again. I don't know what's wrong with it and i was hoping someone knows what to do since this is very anoying Thank you
On i've asked for help on Reddit, but maybe someone here knows a solution for it. I really don't know what to do anymore.

Hello,
do you want to backup your app data? Easiest way is flash KDZ via flash tool with CSE flash (format all).
