Root [GUIDE] How To Restore Service If You've Lost Your MEID

[Darnell0216]

If you encounter problems during flashing, upgrading or downgrading you may fall victim to your MEID/ESN being zeroed out. The usual cause is pulling your battery while stuck on the white LG Software Update screen.

THIS DOES NOT APPLY IF YOU WERE USING THE LONG-ROOT METHOD FOR 2.2.1. THAT LOSS OF SERVICE BETWEEN STEPS HAS NOTHING TO DO WITH THE MEID.

How do I know my MEID is zeroed out?
If you happen to be using LGNPST, it's fairly obvious from the info on the right hand side. If you're just using your phone, from the Home screen click: Menu -> Settings -> About phone -> Status and look for the following:
My phone number: 000-000-0000
MIN: 0000000000
MEID HEX: A0000000000000
MEID DEC: 268435460000000000
Congratulations! You're zeroed out!

How do I repair it myself?

1. Go to Android - whiterabbit.org and scroll down to MetroPCS on any Android phone
2. Enter your MEID DEC from the sticker under your battery or on your box's label
3. Keep the info that appears handy as you'll need some of it shortly. Write it down or screencap it if you think you'll need to close your browser.
4. Google QXDM 3.09.19 and install/run it. It will ask you to download a version of QPST as well.
5. Connect your phone to the computer with USB Debug enabled.
6. On the Command Output tab, enter the following commands:

   mode offline-d
   spc 000000
   RequestNVItemRead scm 
   RequestNVItemWrite scm 0x3a
   RequestNVItemWrite esn 0xXXXXXXXX [i](Your (p)ESN from WhiteRabbit)[/i]
   RequestNVItemWrite meid 0xA00000XXXXXXXX [i](Your MEID Hex from WhiteRabbit)[/i]
   RequestNVItemRead esn

7. Restart your phone.

You should now boot back up with service restored and your MEID back in place.

If this fails to work for you, your other two feasible choices are: 1) Send it to LG claiming a dog ate the programming and 2) Take it to MetroPCS and hope you get someone who doesn't know what you've done to see if they can swap it out. It is not guaranteed to work for everyone.

my phone [LG Optimus M] got bricked, so i used LGNPST to restore it to the default 2.2.1 but now my MEID is zeroed, and i cant figure out how to change it.

this guide doesn't explain how to connect my phone to QXDM, and its really giving me a hard time. any help is GREATLY appreciated.

- Did you install QPST like QXDM asked for?
- In QXDM, click Options -> Communications and select the port for the phone.

 

[cnc3freak]

it gives me options for Target Port and GPS server port. target port only has the option "disconnect" GPS only has 10, 8, and 9.
and yes, i installed QPST

- Is your phone on and connected?
- Did you turn on USB Debugging?
- Did you turn off USB Mass Storage?

 

[cnc3freak]

yes, i have done all of those things

 

[Darnell0216]

yes, i have done all of those things

Launch QPST Configuration and make sure your phone appears in the list with a COM port. It should appear in both Active Phones and the Ports list. If it does, leave QPST open and launch QXDM looking at the Options -> Communications section again.

 

[cnc3freak]

no, it doesn't appear there.

 

[Darnell0216]

no, it doesn't appear there.

It doesn't appear in QPST? Does the bottom of QPST Configuration say "1 client, Server Running"?

 

[cnc3freak]

yes, it does. :|

 

[Darnell0216]

Just out of curiosity, launch LGNPST now and see if your phone is properly connected on the COM port and it can read your phone's info.

 

[cnc3freak]

just did it, it shows the phone, and all the info just the same this as when i tried it earlier

[EDIT] sorry if the picture is a bit much
[EDIT] also, im wondering why it was resized so small...

 

[Darnell0216]

It's alright, I just zoomed in to see the info. Checking something with my phone connected right now to see if there's a step that was missed.

 

[Darnell0216]

Think I may have found the culprit; did you add the port to QPST Configuration? If not, from the Ports tab, click Add New Port and you'll want to choose COM9, which your phone is connected to (at least it looks like a 9 in the pic). The full name will read COMx - USB/QC Diagnostic. The rest should now be active.

 

[cnc3freak]

ok, i see, there was a tickbox that was hiding the USB ports. well, now it shows up in QPST what now? o:
thanks for all the help just getting me this far!

Now you can open that same port in the QXDM menu. Leave GPS disconnected.

so now i just follow the rest of the instructions in the guide?? thank you, i LOVE you, you have no idea xD thank you so much

 

[Darnell0216]

You're welcome. I'll probably update the guide tonight or tomorrow to include the note about adding the port and that checkbox in QPST. I'll watch this thread a little longer to see if you get it or something else happens.

 

[cnc3freak]

ok, i followed the instructions, my MEID HEX/DEC are both niow correct, but the MIN and phone number are 0000000385/000-000-0385

 

[Darnell0216]

Go to the dialer and enter ##000000# + Call. You'll be able to edit the MIN, MDN (phone number) and SID. I believe you can leave the SID alone, unless you happen to remember what it used to be.

 

[cnc3freak]

should the MIN and MDN be the same?

 

[Darnell0216]

The MIN for each area code is different. If you don't know the MIN, try and get it from someone in your area under the same area code. Depending on how nosy your local MetroPCS is, you might even be able to get it from them. The MDN is your phone's number.
