Bricked in the 12 hours I had this phone? :S

Just got this phone less than 12 hour ago.
I have searched everywhere but cannot find any answers.
So first of all, I have rooted, and unlocked my bootloader. I then proceeded to install CM 10.1. Install went perfectly, but when I restart the phone, the LG splash comes on for less than a second and goes straight to a backlit black screen. No matter how many roms I try to install, they all do this..
I have installed LGNPST but when it recognizes my phone, it goes into emergency mode and under DEVICE it says "Unknown"
I have all of the drivers for my phone
If anyone could help me and say what is going on I would greatly appreciate it. I have looked on these forums for atleast an hour before I decided to post this thread.
I have the E971.
Thanks all

Will do, give me a few seconds to download it.

Would anyone help me get the appropriate KDZ tool that I can use that actually has rogers? The ones I have do not have it. Nor my phone model

You'll be fine. LGNPST/KDZ will work.

Download the Rogers 10d from here: http://lg-phone-firmware.com/index.php?id_mod=20#rogers
LG Optimus G E971/3/5

Thanks guys. For some reason, the KDZ updater wont let me choose the file to update/ Instead of the yellow folder to locate the file, the text box is empty and the button to find it is no where to be found...

try a different computer. i'm surprised that i even have to say that.

On the other computer the program crashes :S

In that KDZ updater folder, there is another executable msi file I believe that you may need to install first.
LG Optimus G E971/3/5

Yup use the KDZ method to fix. If you're on rogers (e971) you need to get the kdz from
lg-phone-firmware.com then scroll down and download version 10d.
You can also download direct from LG if you can get the link.
This post links to the original NEW JB update http://forum.xda-developers.com/showthread.php?t=2196742
ALWAYS FLASH CUSTOM ROMS FROM 10D
Run the msxml.msi or get the microsoft xml pack from microsoft.
Run the LG Software from the website to install ADB access for windows.
Put your phone into download mode and run the KDZ updater program.
Wait. If you get a bootloop do a factory reset.
Better tutorials are available on here you just have to look around. This is where I got my info:
http://forum.xda-developers.com/showthread.php?t=2010624

I on the other hand have lost the ability to downgrade. Phone stuck on boot animation after first reboot during flashing with KDZ. I only have download mode available. Looks like from now on the MTP driver simply will not load. Sheesh.
Edit: I got Factory Reset option finally! All is good again. I really had to KDZ this thing like 30+ times.

Exact same thing happened to mine. After 5 days of literally trying everything I went to sprint and they replaced it with a new one.

[GUIDE] Bypass low battery warning on LG Mobile Tool

This might not work for you as it did not work for me but it is the only way I have been able to pass the low battery message so it might work for some. I get a connection problem after step 3
Step 1.
Download tool and LG drivers (if you don't have them) from here and here and install them normally
Step 2.
Remove battery and note down your device model and serial number. Boot phone in to download mode by switching phone off or pulling battery if soft bricked, then hold down both of the volume keys and plug in the USB data cable
Step 3.
Run LG Mobile Tool and wait for the software to tell you it recognises the handset as either being the latest software or a new update is available. Unplug the handset but keep it in download mode then in LG Mobile Tools click on options then update recovery. It will now prompt you to enter your handset details, fill out the top 2 boxes and click ok. You will soon be prompted by a message asking you to plug your handset in, plug it in then press retry. Wait EXACTLY 5 seconds (count 1 Mississippi, 2 Mississippi, 3 Mississippi, 4 Mississippi, 5 Mississippi) then unplug the phone as quickly as possible! Very important, it might take a few tries to get it so just alter the speed at which you are saying Mississippi lol!. If you get the same error message about battery too low then you have failed and need to try it again. Once you have succeeded you can do either of the 2 things below:
3a. Plug phone back in immediately and wait for the file to download and flash (recommended) (I am currently trying this and will report back as soon as I can)
3b. If you are soft bricked and scared you have limited battery then don't plug it back in, pull your battery out and let the program run and it will do everything including download the required software for flashing. When the software is almost completely downloaded, boot back in to download mode and let the downloaded software flash to your phone. (might have an error at software installation this method. I couldn't get it to work I think due to the phone being disconnected for so long.)
Step 4.
MAKE SURE YOU DO A FACTORY RESET STRAIGHT AFTER THE SOFTWARE HAS INSTALLED
Step 5. (Optional)
Download the older version of FreeGee from here if you are still a bit unsure if the latest version will soft brick your handset again.
I have managed to use LG Flash Tools now, even after being affected. I would not advise trying this though, as it was an accident for me. I had the back cover off while flashing a custom rom with CWM. After the rom file was installed, I rebooted my phone from CWM. As the phone was rebooting (was on the rom boot animation) the battery fell out. After I put the battery back in the phone would load to the rom boot animation, but it would freeze on this screen and then reboot and do the same thing over and over (bootloop to animation) - I then tried to factory reset and flash the rom again, with the same thing happening again) - I then went in to restore my phone using a backup through CWM. After the restoration, then phone would still hang at boot animation and then bootloop. I retried restoring and flashing multiple roms and re root the phone with a saved zip file on my phone. None of this was working. I decided to try to use LG Flast Tools again, only this time it actually passed the low battery warning. The funny thing is, I have tried thousands of times even at 100% battery level and lower (when there was nothing wrong with my phone at all) and it has never worked. This time it did (even though I had 66% battery) and still works now, as I just tried it again.

I've tried this method but unfortunately, the update stoped..
i passed through step 3a but when installing the software, around 80%, the lg mobile support tool suddenly disappear.
i'm trying it again for the second time, i'll update after my attempt.
thanks.

Unplugging and connecting when asks for retry helps in bypassing the battery error.still.its just a visual gimmick.

I got in such situation twice... bricked device and getting battery level error (3) even when i had my battery at 100%. Found out after several flash attempts that this problem was solved by flashing the oldest official kdz i could find (v10A). :silly:

I might give that a shot.
HONESTLY WHY! I am starting to get so frustrated that nobody can figure this out! Surely there is somebody out there that can someone reverse the damage that FreeGee caused by way of ADB commands? I just wish I knew what the hell I was looking for

OK guys.. After exhausting all known tricks but failure I just walked into LG service centre andgot stock ROM installed. It took just ten minute for them to install.
I just though given an opportunity, I will steal their laptop n take it home..hahhha..

What exactly did they do? Did you see any of the software? It's not that easy for me as this phone was never released in my country.

I could not see what they did. But I am damn sure he didn't do anything like using button combination to get into recovery or download mode etc. I saw him remove the battery n then reinstate then just plugged in the USB cable!

I deal with this situation 3 time...last time little scary with only boot to cwm ( fix with flash twrp hack by madmack and install rom )...never get same sollution to by pass low bat warning...
I think we just have to uninstall and reinstall all LG driver..restart..and keep trying with 100% batt..
May be LG decide flash or not when we connect via Lg mobile tool via internet..
Because once i have succed flash with only 20 % battery...last time i get low batt warning with 60% batt...
Once you get low batt warning it keep rejecting flash even with 100% battery..
Lol never give up trying is best sollution

sorry for my noob question.
you just walked into LG service centre? they didn't question you about how your phone got into that situation?
i'm afraid that lg might ignore my phone because i rooted and attempt to disable the scurity through freegee..

They have asked me. I just said I was trying to do factory reset n it got struck. But I am not sure if he completely beloved me. It all boils down to how friendly that guy in the counter is. After all ,for them, its just a 10 main job. No parts or labour involved. Just pushing some files.
So just go ahead n try. My phone is also rooted n flashed freegee. But I got the service.

Hi guys,
I'm facing the same problem here but with a G Pad. Can't pget past the low battery error.
I figured a way to make the mobile tool download the files but when it comes to flashing it I get the same error again.
How did you flash the file after downloading it?
Any help will be really appreciated.

2. Flashed stock at&t rom V10g
3. Flashed E980H Panama ROM V10a
And it works, i dont get low battery error, even with ~65% battery... Maybe a try for all with same problem? :fingers-crossed:

[Q] Autorec app bricked my g2?

so i have the sprint lg g2 ms980 with the lastest kit kat update. i was trying to manually install cyangenmod OS but i used the autorec app to access recovery instead of using the hard keys. it is know to cause white lines on the screen and there is a usable fix. i have done and fixed it before. however the most recent time using the app has caused the white lines to become much more severe. i can no longer see anything on my device it will not shutdown only soft reset. that i am aware of, because i cannot see anything, i cannot access download mode or restore mode. also the computer no longer recognizes the device. please help me i am not completely ignorant on these matters but this goes over my head.

If you have custom recovery, just hope power down until screen shuts off. Keep holding down, as lg screen comes up. When it disappears and the screen goes dark. Let go. Phone will be powered down.
Hold volume down and power. Keep them both held down until it says loading recovery.

okay so i fixed it. umm there were alot of steps involved. you must flash each partition individually and extract them from .tot file. then you can change com to 41 and use lg flashtool to restore to stock rom zv7-zvc. i have not seen the zvd.tot file but the zvd update has relesed for sprint. if more detail neccessary repy.

No tot die zvd. Just a little update. Where zvc was a major change.

LG G3 D851 stuck in BOOT LOOP, Model Information missing Error (w/ pics), help! lol

Hi XDA family!
First I want to thank everyone for their hard work and contributions here. It's amazing community of work and collaboration developers and testers have contributed here.
Ok, now to my issue, I have a LG G3 D851 T Mobile that is stuck in a fast boot loop it only shows the LG logo then turns off and repeats over and over unless the battery is removed. Each cycle takes place in a matter of 3 seconds.
It won't let me post pictures (links) in my post because I am a new user but here are the error screen shots: just change hxxp to http:

I have tested various methods in the to flash back to the stock firmware Kit Kat 4.4.2 without any success. I have tried the .TOT method with the correct files and also the model information bypass .dll ( LGUP_8974.dll) and the .KDZ method.
1) Where I am getting stuck on the .TOT method is: Model Information Check FAIL!
2) Where I am getting stuck on the .TOT method with the bypass model check is:
Error: [14: 622] CrossDL [] to D851. SWversion
3) Where I am getting stuck at using the .KDZ method is during the S/W Upgrade is in progress , ALWAYS stops at 4 % !
I've tried this 50 times at least, it always stops at 4% no matter how long I wait or how many times I select Retry, I get the same error pictured above.
Can someone please offer any help what to try or where to go next, I'm stumped! I just want the phone to boot up and work lol, Kit Kat or Lollipop, it doesn't matter, just a working LG G3 for T-Mobile back functioning.
Please help!

Anybody?

My friend is going through the same thing, only way to get it to boot up is plug it into the charger. From my searching it seems like its a battery issue, not sure how it can cause it to reboot. Several people have claimed that a new battery has fixed the issue.

Wow, that's interesting actually!
I know the charging does seem to be acting a little strange.
This is my first LG actually and since it's been in boot loop I charged it in a powered off state and the battery went to 100% in a matter of 10 minutes which seemed odd because after testing it for just 5 minutes and plugging it back in it was showing an empty battery signed with the yellow triangle warning.
So perhaps LG unlike Samsung is more finicky when it comes to being powered enough for the Flash tool to read all the settings and what not. I'm going to try Pagel's .TOT guide again and if I'm still getting the same error I will see if I can get my hands on a good battery. Thanks!
Any other help and recommendations are much appreciated!

LG G3 S D722 is hard bricked and I really need help.

My G3 is stuck on the booting screen and nothing works. I can't go to recovery menu. But I can hear my notifications, no calls though.
I tried to root my G3 using kingroot then replacing it with SuperSU. I restarted the phone after just to see if it's ok then this happened. It wouldn't start up. It just shows the "LG: life's good" thing and doesn't do anything else. I can't even go to recovery or download menu.
Now soon I am going to send it for repair. There is important stuff in my phone though such as pictures, text messages, my gmail and other accounts.
Will they be able to see it if they manage to repair my phone? a relative told me that I erased my android operating system..
Hopefully someone will help me here.

I'm no expert regarding phones with LG ROMs, but you might have had a locked bootloader. If i remember correctly, my old G2 needed its bootloader unlocked before doing any fancy stuff. I now have a G3 and i'm terrified to do anything to it. (After some nasty Soft & Hard bricks on my G2)
Can you explain better what you mean by "replacing Kingroot with SuperSU". Did you have both installed at the same time or what? Some people had problems with Kingroot that it would lose root after you reboot it (G3)
You say you can hear notifications, how can you hear them if you're not booting the OS? You said it's stuck at LG logo.

Ok I managed to get to the factory reset screen by holding the power and volume down button. I confirmed it, it said "Factory reset processing" then "erasing.." with the android logo for like 2 seconds, then it disappears and goes back to the boot loop.
