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; take your battery out. With the battery out press and hold this combination of keys: Back key + Camera
. With the keys hold down plug in your charger to the phone. (AC connected to the wall or connected to USB) Your phone should boot to S/W Upgrade mode. Now the battery can be placed back again. If you got to S/W Upgrade mode by the AC charger method now its time to connect phone 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
extract the folders somewhere on your PC. While on LGNPST navigate to the extracted Bin folder and select it as the .bin file. The file name should be MS690ZV7_08.bin
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 to 2.2.2. And also unbricked.
Hope this helps.
PS Thanks to sammyz for the 2.2.2 link.
