[Q] Problem with LGNSPT

Hey guys i have a concern.
I have the LG Optimus G (sprint). Now I rooted it and that went swimmingly but when I tried to unlock bootloader using freegee app, it soft bricked my phone. It either stops on the LG screen or when I hold volume down+power key, it will shut off and then turn on or shut off completely. No worries because I can put It into download mode right? Well once I do that and connect it to LGNPST, I cannot locate the .dll file I need to actually try to restore phone back to stock and I have the .dll file.
This is the only way i know to fix my phone that actually works and won't hard brick my phone. Does anyone have any ideas? It will be very appreciated.

Did you register the dll?
6. Start a command prompt as admin
7. Type regsvr32 "C:\LG Electronics\LGNPST\Models\LGNPST_LS970.dll"

So in reference to your picture in Adri's thread... That com port seems awfully high me. See if there's a way to change it. It seems the Com ports are usually 3,4 and 6,7. But then it all depends on your computers configuration.

[Q] G2 stuck at boot logo no download mode no recovery device manager wont recognize

ok i see lots of threads about G2 stuck at LG logo with no download mode etc but none specific to my situation so figured id start my own.
my phone is stuck at the lg logo when i try to boot, when i try to go to download mode it shows the blue dots but windows, flash tool, nothing will recognize the phone as being plugged in, and not even the little sound windows makes when a usb device is plugged in, its been a little while so i cant remember EXACTLY what the last thing i did that bricked it was, something i did on command line with aboot something, i can try to dig it up if absolutely necessary but it would take some digging...when i try to boot into recovery it freezes at the "loading recovery screen, when i try to go to download mode it sticks at the blue dots and wont respond to anything, when i try to do a factory hard data reset it says "hard reset processing" or something similar then freezes there, ive tried reinstalling the drivers, using different pcs, read through countless threads, but have had no luck, any ideas what i can do to unbrick my brand new g2?? thanks in advance

This is what i would do....looks like your cable works, looks like you know how to get into Download and Recovery Mode. You have to get it to be detected, if it boots into Download mode it should work. Try re-installing the drivers.

with the phone off (completely), hold volume button (up i believe), and plug usb into computer. This should bring up download mode. If volume up doesnt work, try volume down. If you get just to the dots, then your download mode is broken.

Do you have a windows 7 PC? if you do, then you should not have any problem.. Phone will show up under com ports in device manager bit the com ports are hidden by default.. Further, you don't need to reset dates for lg flash tool, just search for megalock.dll file , google it...also google how to enable com ports in windows 7... You should be good to go

First of all, for that procedure and for the pc to work you need to get your phone on download mode (hold vol down button and connect phone to pc via usb cable). Are you still in bootloop? can you get to recovery?

just Google 'enable com ports in windows 7 device manager' and follow the instructions
Sent from my LG-E980 using Tapatalk

Try this.
In the part of the instructions where you disconnect the phone for 5 seconds, try disconnecting the phone, pulling the battery, and re initiate download mode (by holding volume up and volume down while plugging the USB cable into the phone). My green bar started moving immediately when the plug inserted into the phone. I've been trying to get this to work for the past 3 days. I hope it helps.

[Q] My G3 is Softbricked - $20 to the first person that can help me fix it!

I'm going crazy here and I need my phone to work!
I have an LG G3 on Verizon.
I rooted it and edited a part of build.prop to change the DPI which got the phone stuck in a boot loop and kept popping up "the process com.android.systemui has stopped.
I tried clearing cache
I tried booting in safe mode
I then did a factory reset
My phone boots up to the Setup Wizard screen but I am STILL getting that systemui error and a com.android.phone and I can't get any further than that screen.
I then tried to use the LG FlashTool to just wipe the entire ROM and replace it with the stock one from Verizon.
This gave me a "Model Information Check FAIL!" error but I DO have the right ROM for my phone. There's only one for the Verizon G3 as far as I can tell
This led me to realizing that there is something in the build.prop that's making LGFlashTool think the proper rom actually isn't right.
I then installed the Android SDK so I can ADB into my phone. but whenever I run "abd devices" nothing shows up in the list.
I was told USB Debugging needs to be turned on in order for this to work, I don't remember if it's turned on or not with my phone and I can't get past the Setup Wizard to edit anything. I wonder if ADB is even running properly on my phone or if these errors are stopping it?
I will gladly paypal someone $20 if they can get this working for me.

One of my friends saved his phone by this guide

Download mode - LG PC Suite - Restore update error.
1. Remove battery
2. Boot phone into download mode
3. Open LG PC Suite - restore update error
This method have saved me a few times.

Will adb work in one of the recovery modes even if it wasn't enabled in the full boot mode? If so, start there.

Regarding your USB debugging question, you would have had to turn it on in order to root the phone originally, right? If so I imagine it would still be on unless you unchecked it. You have the proper drivers set up? Anytime I've encountered issues with adb devices not returning any results the issue has been drivers.
Good luck.

Flash stock zip kernel from artmod thread.

the problem is. I can't upload any files to mobile phone. if i connect to pc, it turns on, goes to recovery, so I click on mount storage, and other mount option, nothing happens. My computer detects phone as F180L with a exclamation mark.
If i go to download mode, and then try to flash any KDZ file from all the f180 KDzs. It gives me errors.
LG Support Tool on entering serial number and model name says "check out serial number and model"
ADB never detects my phone. So I can't upload anything.
No option to upload files via SD Card.

ok, so I have no clue what happened :crying: phone was in download mode. I did nothing, but only installed LG Support Tool USB driver, while the mobile connected.
Then I installed Microsoft .net framework 4.0. And my phone is now qhs_usbdload. it's officially bricked now. I have no clue what happened. This is all that happened before I restarted and selected "reboot to bootloader" and its dead. So there's nothing left to do but throw it out

WTF OKAY! I have no clue!
But, after seeing that qhs usbdload. (i have seen that before with other phones). I complete lost any hope.
So I for feeling contended, downloaded qpst, and emmc software download, and selected MPRG8064.hex and msimage.bin.
Then like I expected it threw an error "image download failed, cookie if present not received"
so I lost hope disconnected my phone and put it there. After a few minutes thought I should try one last time.
so I connect it my pc and VIOLA it turns ON!?
now I have that same rebooting to recovery problem. I have no explanation for whatever has happened to phone in past 3 hours. I have been with phones for years. This is the weirdest thing to happen ever :angel:
Now someone, please help me?

1. Why is this in Development section?
2. You can't mount internal SD as USB storage. Use adb push or adb sideload instead, that will help you to get the files onto your phone.

Some user got that problem before. I am not sure about how they solve it but I guess that they flash their original KDZ back. If your phone can enter download mode, you should try LG Flash tool 2014 and flash your original kdz to restore incorrect system image.
About adb cannot find your phone, try to remove adb driver from device manager and reinstall LG usb driver.

My phone is acting weird. Sometime it would start. Sometime the red light would blink. Sometimes the red light wouldn't blink at all. Then sometimes, it starts. And then it doesn't.
I have no clue what is going on with it.
But it went to download mode many times again, it would go to fastboot, bootloader, recovery etc. Then sometimes it will not respond to any buttons at all! I know its battery is down, but idk if it's charging or not?
I don't know how to know whether the phone is charging or not. I left it charging for 30 minute, and it didn't even buzz. :crying:

One thing you can do (I've done it in the past a couple of times) is to crack your phone open, disconnect the battery, and charge it with an external charger. That would at least give you a full battery to start with...

Regarding the charging problems, I had that once. I was able to startup the phone by simply using a 2A charger instead of the LG's 1.2A.

When I had this issue it was charging while in recovery. Please look at this post and flash your kdz.

thanks. but after charging it. I couldn't turn the screen off because it goes in recovery. I turned off the phone after good 30 minute charging. Then went to sleep.

Hi, regarding that. I was able to sideload exitrecovery.zip file. It goes to 100% then nothing happens. Nothing happened on phone screen as well.
And can you send me link to that stock zip kitkat? i have a miui.zip and few other roms that I have not tried. thanks
Edit: also what should I do about adb, am i doing correct?
Becuase in adb devices, my device is displayed with deviceID sideload
And i have only pasted adb folder, with a dll and a zip file, there is nothing else, do I need to install SDK?

I tried lg flash tool 2014 again, and it flashed, I swear yesterday I tried to flash it, and after clicking on it, it never showed me country and language selection menu, so it would sit there and do nothing. now I don't know how but it did it :laugh:
thank you so much you'all
