There's plenty of tutorials for flashing .TOT files in LGNPST, try JHoopes' thread http://forum.xda-developers.com/show....php?t=2013067

The same instructions are also found in carret's guide: http://forum.xda-developers.com/show....php?t=2006946

All you had to do was actually look.

Hi,

I need a little help with this. Every time try to use KDZ_FW_UPD, it gets stuck while unpacking the KDZ and the program just crashes every time. Any ideas why?

should reboot normally, then as it reboots into the welcome and get-you-started screens, lparam will slowly count up to 100 before returning to 1 again, that is when you can safely unplug the cable.

can you find your KDZ on LG's server via the LG app, and download it as a KDZ file?

if yes, it may work on Sprint and afaik it will not further harm your device even if it doesn't solve your problem, you can also PM thracky for more advices as mine is a GSM set.

the KDZ of modern Optimus-es can be bigger than 1GB for some (carrier dependent), and thus may take a while to unpack.

also, have you tried re-downloading the KDZ? as it is a large file, the download may be bad/corrupted.

what are the specs of your computer?

have you tried on another computer?

So after installing the CM10.1 Canadian version for the Optimus G, I tried to restore the phone to my stock rom and it was bricked. I used this guide and everything worked.

Now I bricked my phone same way as I decided to try the new build they released of CM10.1 and thought restoring would be no problem as I have already done so a few days ago. This time everything updated and the phone rebooted, but it is stuck at LG Logo. I tried running the wipe.bat, all I see is the cmd window pop up for split second and exit, but the phone won't reboot from recovery, so I reboot manually but I am still stuck at the LG logo.

Is there a way I can fix this?

Here is the log

Ok I have figured it out. If anyone is having a similar issue here is what you do:

First follow the guide in this thread, if you are still stuck at boot logo even after the manual wipe power off your phone, hold down the power and volume down keys to enter factory reset mode and click power again to confirm a factory reset. This worked like a charm for me
