Plug in the phone and run lgnpst, look on the right side, if there is a bunch of 0's you need this guide:

If on the side of lgnpst your phone number and other random numbers appear, you probably need to update your prl, this guide will help you:

If you manage to get service but your phone number is wrong and not zeros I am working on a fix for this, hang tight...

so which esn do I need to input in command.. I see 2 in whiterabbit.. one says ESN Hex...and ESN Dec?
 
Hi, I take it from the drivers you mention that you have a windows machine. I got to the point of having the right key combination to get the software upgrade screen. USB finally is recognized, even though it's not in fasboot mode. However, it's recognized as a modem, and fastboot and adb don't recognize it. Anyway, what should I do after I get that screen on a mac?

Man on a MAC you will not be able to unbrick it. In order to unbrick the phone you need to run a program called LGNPST.exe. If you really have to do it on a MAC you will need to install windows as a Virtual Machine. Then follow the whole guide.

Hope you get the phone back.

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.


Thank you for the great tutorial. Worked Perfectly. A little trick that i found is to plug the phone into the charger without the battery in. When it say insert battery hold down vol down + back + camera and power and insert the battery. I somehow did it by myself no need to let the battery die. Thanks again

(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.

it also works to remove battery, do buttons then plug in. right into emergency/dev mode. in lgnpst install scr, eri in emergency then prl. go to "meid fix" thread with qxdm and reprogram from all zeroes. you can skip the write esn line, probably won't work. then you're back to 2.2.1 stock. gingerbreak to root. easy way to downgrade from 2.2.2.

Hello I wonder if you can help me I seem to have bricked my LG Optimus Chat C550 Android phone by using a rom manager and it didnt like it. Now all I get when I turn on my phone is an LG boot screen and its stuck and the lights on the qwerty pull out keyboard flash on and off, the computer dont recognise the phone when plugged in by USB cable. Have tried your suggestion but my C550 has no camera button and the back key is not a key as such its a 'touch' sensitive key - the only proper button keys are the send and end buttons and the volume up and down button and the pull out qwerty keyboard - am I stuffed do you reckon? please help if you can I really liked this phone before I bricked it :(. Thanks in advance for any help/advice. Andy from Ireland.
