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.

Try flashing the rom less than 1 GB using the KDZ_FW_UPD.exe with CS_Emergancy mode it should work if your phone have enough battery power to keep it on in download mode for 10 minutes or so, if not then try through LGNPST using tot file. Or check if it charges in the custom recovery.
Correct me if I am wrong

Turn off your phone and put it in download mode by pressing and holding ‘Volume Up’ + ‘Volume Down’ and inserting USB and use the software to flash KDZ that I attached the screetshot, KDZ_FW_UPD.exe, this one can't flash the KDZ file bigger than 1 GB so if your KDZ is more than ! GB in size then download one that is less then 1 GB recover your phone charge it then flash your desired one. You are using the R & D Tool it always check the battery level and not allow you to flash if battery is less than 50%.
Note: If you have the mako bootloader install this tool might not flash the kdz (It never did for me) to come back to full stock you will have to use the LGNPST

If it's of any help, I had exactly the same problem just a few days ago... Read from this post further down, there were some suggestions from folks, and the final solution to my issue. Long story short, KDZ Updater can work with the dead battery, if you manage to find a KDZ that can be flashed with it. I found a 1.17GB KDZ that I was able to flash (any others, just slightly larger, would give me an extract error), and then just took it from there.
As mentioned, TeenyBin and LGNPST might be another solution, but I have no first-hand experience with it, so I can't comment...
Oh, and BTW, you are saying you "tried to use KDZ Updater", but your screenshot shows the LG Mobile Support Tool -- that's a different application, and a different process. Look at a screenshot by @hackenggr a couple of posts above -- that's KDZ Updater.

That's exactly what I did. Flashed a KDZ (1.17GB in size, the smallest I could find) with a KDZ Updater. Low battery didn't matter.

Then I don't know... I told you what fixed the problem for me -- finding the smallest KDZ that could be flashed. If it doesn't work in your case, look into something else, like TeenyBin.

I think because you decive is converted with mako bootloader LG software not found the LG phone so they stop.
Use the LGNPST to flash the E975 tot file same way you did with teenybin just rename the .tot to .bin and you will be on the LG stock and software will work fine to your desire KDZ

[Q] Bootloop after System-file edit

I rooted ym LG: D855 (32GB) SW: V10e EUR-XX then I tried a memory tweak by editing the /System/build.prop
After a reboot I ended in a bootloop. I tried to factory reset my phone by "Power+Vol-Down" but that didn't fixed it.
Then I tried to reinstall the stock firmware from: http://storagecow.eu/Xda/LG G3/Stock/http://storagecow.eu/Xda/LG G3/Stock/
But I wasn't able to install the chosen: "Germany D85510A_00.kdz" on my phone.
I used the "UpTestEX_mod2_marwin.exe" and followed the instructions, but at the end the LG-Support-tool just gets a connection error message and told me to restart the phone after plugging the battery off and in again. :crying:

I am able to restore the image file by LG Flash-Tool 2014 but sadly I have so bad speeds
After waiting 8 minutes the processing bar on my phone has 1% this means I have to wait 15 hours to transfer the firmware -
Whats wrong

Bootloop

That was my calculation... In my case I had a reset @ 10% after 2 hours and currently I try it again.
I wonder why the download mode runs so ugly slow!

Rooting problem...bricked?

Hi,
Sorry if this is in the wrong place.
I literally just got a G3 D855 and tried to root it using One Click Root. I followed all of the steps and after having to manually boot into download mode, it said that it had completed the process and had rooted successfully and the phone restarted.
I now cannot get past the LG logo. I have tried factory resetting as I can access that menu, and I can only access download mode if I plug the phone into my computer whilst holding volume up.
I don't really know how this happened. If anyone has any advice, please send it my way.
I have tried battery pulls etc.
Thank you.

Authorization Error #11

Hi there. I recently decided to try to root my LG G4 32 GB Cermic White VS986. It didn't end very well. I realize now after intense searches that I tried to root with an old system file, and ended up kind of bricking my phone. I am stuck in the bootloader, with the LG boot logo coming up, then a screen that says "Start Up Failed" with "Authorization Error #11" at the bottom, then the Verizon logo with the device turning back off. I have tried resetting it through Recovery Mode and trying to use LG Bridge to reset it. Not many solutions seem to be coming up. I would appreciate any help at all, as the other option would be to take it in to Verizon, and I know how steep their rates can be. Thanks! Unfortunately I am unable to post images as I am a new user, but if anyone feels they have an idea of how to fix it, please message me and I will send images.

Can you get into download mode?

Yes I am able to.

Then you should be able to load any of the kdz files. If you were already on 13b make sure whatever kdz file you use is also 13b.

Thanks for the help. I did my homework after I screwed up and found how to flash the kdz back in. I also got the proper root afterwards. Thanks!

Also I apologize but could someone tell me how to close the thread? I'm really new and cant seem to find a way to ?
