2. Install msxml.msi
3. Install LG United Mobile Driver
4. Reboot Computer
5. Disable 'LGE Virtual Modem' in PC's Device Manager. (In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.)
6. Power off your device. Press and keep pressed "Volume up"+"Return"+"Power" and connect USB cable to phone
7. Yellow screen with text emergency mode should appeared
8. Run LGMDP THUNDER v1.5 (Operator).exe from the extracted folder (Has administrator).
9. Press "Select Port"
10. Choose your device and press "Connect"
11. In the 'Image Folder' space, browse you uncompressed Android 2.3 [LG-P500.RU].zip

The firmware flashing process is now underway.
If all goes well, in 5-10 minutes the phone will be flashed with the new firmware.

This is one of the original guides for flashing full firmware.

I think you missed out on any of these things:

1. Disabling modem
2. Msmxl installation
3. LG mobile united drivers.

Alright man, gonna try again following those instructions. Will get back :D

Edit: once it goes into emergency mode (yellow screen) the computer won't recognize my phone when I plug it in. I installed the universal drivers, that was the only thing i hadn't done yet. Duno what else to try...
Edit2: tried all over again on Win7, worked like a charm. Got sweet GB running on my p500 :D

    P-509 Old Baseband (v10S)

    I've noticed that no one on these forums has ever posted the old baseband for us Optimus-T users who applied the new baseband but want to revert to the old baseband given that the old baseband fix is available (http://xdaforums.com/showpost.php?p=35924286&postcount=2). I finally got around to doing extracting the old baseband files myself (with DZDecrypt) from the v10S KDZ and packaged them with the tool from this thread. This means that a full restore with the stock Froyo ROM is no longer necessary to get the old baseband. Just run the tool in my .zip as you would the tool in the original post to return to the old baseband and flash the old baseband fix to get compatibility with new baseband ROMS.

    Will an admin or the OP please place my attachment in the original post so that us Optimus-T users no longer have to go the longer and more dangerous route of a full restore to get the old baseband? Attached is a screenshot of my phone with the old baseband running the Oxygen Gingerbread ROM.

    Thanks!

    Reviving a dead P500!

    Hi,
    I'd like to share my experience for those having problems with nv2.
    3 days ago, my Optimus One couldn't boot at all. The only working part was the Emergency Mode. KDZ couldn't fix this as it didn't recognize the chipset.
    I used LGDMP and upgraded to V20 Romania, but there was no signal. I figured out that the NV2 was gone! But the good point was that luckily I had backed up my NV2 a few months ago. But I couldn't restore it at all. LGDMP said: "NV2 file doesn't exist". Actually this file should be in a folder named as "_COM_6_". Notice that 6 is the COM port I used in my own PC. Yours might be different. Then create another folder having the same name as your IMEI and put _COM_6_ in it. For example: LGDMP/3540430**********/_COM_20_/NV_P500_20110808-212402.nv2
    But the point is that the NV2 can't be restored while the phone is connected to your PC in Emergency Mode. So all you have to do is to install a ROM, whatever it is (I used CM7), and enable USB Debugging, and then connect it to your PC. Now Open LGDMP and Select Port, and finally NV2 Restore.

    I was happy I could bring my dead mobile phone back to life.

    I hope this can help you.

    Which file should i flash if i want to switch to cm7? If i have to flash p500 v20g baseband to get back to cm7, the name seems to be a misnomer.
