LGNPST will restore your Sprint LG Optimus G back to stock, no matter what you have done to it as long as you can get your device into download mode.

LGNPST Download:

Stock Sprint LG Optimus G Firmware / Rom Download:

How to Return/Flash Sprint LG Optimus G back to Stock:

  1. Download an extract LGNPST to your PC. Run install.bat as Administrator to install the necessary programs. (Right click the file and click Run as Administrator)
  2. Download the Stock Sprint LG Optimus G Firmware you want.
  3. If the firmware is .tot, then rename it to .bin
  4. Launch LGNPST
  5. Plug in your phone and put it in download mode (power phone off, press and hold Volume Up + Down and then press Power button)
  6. Go to file>select dll and pick lgnpst_ls970.dll
  7. Pick the bin file under bin file.
  8. Click Start

Note: If your device restarts at 67% or 85%, don’t worry. The firmware is fully flashed and the device should reboot on its own. If LGNPST errors out at 85%, after a few minutes turn your phone off and hold the power button until the phone powers on, then release.

My phone keeps doing the thing where it errors out at 85%. I then wait a few minutes and reboot and it boots me into recovery mode. Any suggestions?

Awesome worked perfectly – I bought an Optimus G from craigslist which was rooted and had custom ROM and was worried to see i could not upgrade to Jelly bean. Thank you very much – this worked perfectly.

When i download the lgnpst link i get a file called lgnpst_acg. Not sure if this is the correct one. And when i try to start it nothing happens, even when i run it as admin. I extracted the file, put phone into download mode and tried to run the program and nothing happened. Please help.

Mine got the error at 85%, but I can’t turn it off. No matter what button combo I try the screen goes blank and comes back up in Download Mode. Stuck there.

Tim on 15 November, 2014 at 4:17 pm #

Mine goes well then reboots at 67% somehwere in the but then get stuck on the 4g lte screen. what you have to do from the is dissconnect from computer and turn phone completely off. hold volume down and power down until your home button on the bottom lights up the release them and then let it boot into recovery mode. do a factory wipe and cache wipe and it wont get stuck on 4g lte anymore and then your done. no more hooking back up to the computer.
