So many users have been using Rom Manager and are getting stuck at the Lg Logo. Well now there`s a way to unbrick your phone and avoid the need of a replacement.
To get your phone to be recognized by the pc, you need to let the battery die. In other words let the phone shutdown by itself while it is at the LG Logo. When the phone is off, press and hold this combination of keys:
Vol Down + Back key + Camera + Power button. With the keys hold down plug your charger. (AC connected to the wall) Your phone should boot to S/W Upgrade mode. Then connect it to the pc.
Now make sure that LGNPST and drivers are installed on your pc correctly. (Go
here if you need to install LGNPST and drivers. Follow the guide until where you need to open LGNPST.
Then Open up LGNPST and make sure that the program recognizes the phone. It should be under the EMERGENCY tab. (Dont worry if is says UNKNOWN under Model).
Now Select the dll file. The file name is MS690.dll where it says dll.
Then
Download this file and select it as the .bin file. The file name should end as .bin (So need to unzip to somewhere on your pc)
Then click start. Let the process get to 100%
Now your phone will try to start up but the battery will blink or charge. If it`s blinking all you have to do is: plug it to the wall let it charge a little bit, then turn it on. If it charges then let it charge a little and then turn it on.
Your phone will be back to stock mode. And also unbricked.
Hope this helps.
