Hello People !!

I am writing this now, as i flashed wrong recovery and was stuck at LG logo in my optimus pro device !!

By following the steps below, i was able to get back my phone exactly how it was before (without loosing anythin)

things you need
KDZ updater : Google It
Original LG OPtimus pro Firmware: http://csmg.lgmobile.com:9002/swdata...00/V10H_00.kdz

Step 1
Quote:

Go to the folder where you have downloaded the Firmware Updater : KDZ_firmware_updater and extract it. Install msxml.msi

Step 2
Quote:

Disable the Lg Virtual modem in device manager. Its under Modems

Step 2
Quote:

Boot up your phone in Emergency Mode by RETURN+VOL UP+POWER.
Its like bright yellow with Emergency mode written

Step 4
Quote:

run KDZ_FW_UPD.exe. and connect your phone (emergency mode) via usb.

Step 5
Quote:

In the window, select Type : 3GQCT Also select PhoneMode : DIAG

Step 6:
Quote:

In the place where you have to give path for KDZ file, select the ROM you have downloaded using the link you made for your specific firmware

Step 6
Quote:

Perform Launch

If it is successful, it will restart your phone and get you back to the basics.

Hope it helps,

No u don't . To dowload your original firmware. Replace p690 in d URL with c660. Also put ur s/n d corrct position in d URL. If u still face any prob let me know.


Edit: pm me your serial no and I will get you the link to your firmware and u‘ll b able to dowload
