Mine is in good condition. Not a single scratch on it. Looks new. The only thing it has in finger prints but that can be cleared with a napkin :b

For sure like I said before. Its just a matter of taking the time to try:D
Lgnpst might be the best bet

Well now I need a guide.. Google is my friend xP.. Thanks Blaxican25(Made a guide)

Phone reboots when I try to push the prl. Don't know why.
Also tried with LGNPST but it didn't push the prl to the phone and it didn't ask for my spc either :banghead: :frown: :dontknow:

In qpst did you entered the button "read from phone" in ordeed for qpst to ask for the spc and if you did did the program read the information of your device?

It asked for my spc and when it started reading from the phone it started to load. I go to the tab that says "roam" then i choose the prl 3027 from the option that says "Preferred Roaming". I click on "Write to phone" it gives me an error that says "The model of phone on com8 has change. Do you wish to close this connection?" I just click on no and it gives me the error mutliple times. Do'nt know what to do.

That's what it suppose to do but besides changing your prl also change your spc code on settings tab i suggest "000000" if its like that already try changing it to something else and also program the phone thru qpst on the cdma tab input your phones info like mdn and min

Can you help me with that? Cause it does ask me for my SPC code and when I put the spc code on the area where it says Service Programming: My SPC code.

But as far as the CDMA tab I do not know what to do.

I'm Sure You Know What Your SPC Code Is Correct? The First Thing To Do After You Have Your Phone Connected To The Computer And Qpst Is Open "read from Phone" Enter The SPC Code That You Got From checkesnfree.com And Enter It Your On The Settings Tab As Default So Change Your SPC Code Were It Says Service Programming To "111111" (Example) But It Can Be What Ever You Want Then Go To CDMA Tab And Enter Directory # Is Your Phone # And IMSI_S Is Your MIN Witch I seen Another Member Of The Forums Already Gave It To You And Finally "Write To Phone" Check About Phone After It Reboots See If You Can See Your Phone # And Min # Instead Of Unkown

So For Some Reason Your Phone Is Rejecting The Programming Something Must Have Been Deleted When Your Were Downgrading Cause At The Begining Of The LGNPST Downgrading Process Its Says Something About "NV" I Assume That Has To Do With Your Network Configuration Have You Already Tried Downgrading Again To ZVB? Does Your Device Connect To Wifi And Does It Mount Your Sd Card On The Computer If It Does Maybe Your Missing Files On Your System Files But It Would Require Root To Put Files Back Into The Phone And You Would Need Somebody Else With More Experience To Help You With That, Sorry I Wasn't Able To Help:mad:

On The Lg Hidden Menu ##5473784236368 This Also Suppose To Ask For Your SPC Code Theres An Option For "Mobile Networks" Then "CDMA Subscription" This Would Give You Two Options RUIM/SIM And NV Make Sure Its On NV Even If It Is Try Chaging It To RUIM/SIM And Back To NV My Phone Works On Both

okay it was on RUIM but i changed it to NV. Now it gives me an error that says "You entered an incorrect service programming code. The phone will not accept any read or write commands for the next 10 seconds. Please enter your phone's service programming code:. I put in my spc and 111111. And that error comes along with a WARNING: the model of this phone on port com8 has changed. Do you wish to close connection.

That Was Weird That It Was On RUIM Instead Of NV But The SPC code Is Still Going To Be The One From checkesnfree.com Cause Qpst Wasn't Able to Change It to 111111 Correct? If Is Not Either Or Try "000000" Did The Phone Reboot After You Changed The Settings In The LG Hidden Menu?
