Hi, because with last update increased count of people with bricket phone, I just tryed search for way how to repair this phone. It seems, that last possible way how to save your phone is emergency mode.

I would like to notify you, that I didn't tested it (I'm had not luck enough to brick my phone yet ). I just searched and tried write this for help to others.

So, let's go on.

1) If it's not possible connect to phone via ADB (in Adroid SDK/tools run "adb shell") at all you will try next steps. If it will work, you can use another, verified tools like custom recovery or KDZ_FW_UPD (search on forum for more) [HOWTO] Flash original firmware on P500, )

2) If you fail in previous step, you can try enter into emergency mode manually and try to flash ROM with KDZ_FW_UPD:
  1. Download KDZ updater and uncompress it
    http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html
  2. Install msxml.msi from the uncompressed directory
  3. Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)
  4. Turn phone off somehow (remove battery etc.)
  5. Install drivers properly
    • Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
    • Install the LG drivers by selecting the update manager from the lg site
    • Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
  6. Press and keep pressed "Volume up"+"Return" and connect USB cable to phone
  7. Yellow screen with text emergency mode should appeared
  8. Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
  9. Run KDZ_FW_UPD.exe (Has administrator).
    Select Type : 3GQCT (I have one report that CDMA mod works too)
    Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
  10. I Recommend do not switch phone off. There was some people, which done it and after they were not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....
  11. In KDZ file : Choose the ROM file you downloaded in the first step
  12. Press Launch software update
  13. Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
  14. Make sure that all update was done successfully. Phone should restart itself automatically
  15. Disconnect the USB cable from the phone
  16. Press the three button combo for HW reset of device i.e volume up + home + power button
List to do based on Zecanilis's [HOWTO] Flash original firmware on P500

3) Still no success? Wait for more "What I can do" or just go to LG and let repair on them.

http://android.modaco.com/content/lg...erence-thread/

Please let me know if it works. I just searched for way and I haven't possibility to test this steps for now. I will do update if it will be necessary, same as I will try describe more about software which I founded.

Some experiences from thread(s):

Quote:

AVanover5: ...It works if you set the mode to CDMA and DIAG. Just to let people know. Not sure if it'd work without the recovery screen or not. I never tried it ironically, haha. Thank you guys.

geejay2: ...Bricking seems to be easily achieved by forgetting to disable the LG Modem driver. Apparently the modem driver interferes during flashing. Also I noted that kdz is not stable under Win2k, I switched to WinXP to flash successfully. I saw several aborted flashing attempts in WinXP with modem driver enabled.

domenic_s:KDZ_FW_UPD doesn't work (Application cannot start) -.- Using Windows 7 64bit version. //edit: allright tried another pc (win xp 32bit) and yeah - it worked... I'm so happy.

About shaking (sorry, but I still can't believe... )
Quote:

salte_eskil:wow! shaking the phone really worked! seems kind of stupid but thanks to you all at the xda forum for tips and tricks
4wd vege: Now unbricked. Strangely kdz updater only saw my phone after shaking!!!
me2kimi:
It sound crazy to shake the phone while at emergency mode. I's crazy but it magic. ...So what I do is connect to usb, Launch software update at kdz while shaking the phone. Then after that kdz is working like normal.

Did you had phone off before trying this? And also battery should be charged. I just added this things...

If event that it not show you emergency mode, LG service and warranty is probably the only way how to proceed. Sorry. But I will be searching if another way will exist...

Good work @The_ERROR.

It should work. I think you should also add that the phone mode should be set to Emergency (and not DIAG as mentioned) in the kdz updater.

Good to know - do you know differences between CS_EMERGENCY and EMERGENCY?

Recovery Phone?!
Hello,

Had anyone tried "Recovery Phone" from the LGMobile Update app? It's under the "Customer Support" menu. Enter IMEI or S/N and see if it can bring it up to life.

Cheers.
