This guide is intended for those who:
- Lost their IMEI and did not back it up
- Lost their IMEI, which now reads "0" (one zero)
Operating system needed: WINDOWS
If you are running OSX or Linux you can emulate Windows by using Parallels (OSX) or Virtualbox (Linux)
Things you need:
- Rooted stock ROM (Root66 preferred)
- Download QPST from the link above
- Write down your IMEI (you can find it on the back of the phone behind the battery)
- Turn on your phone
- Open the keypad and dial *#22745927
- Enable hidden menu
- Go back to the keypad and dial *#7284#
- Click Qualcomm USB Settings
- Select RMNET + DM + MODEM and click ok
- On your computer, open up Device Manager
- Locate Ports (COM & LPT) and expand it
- You should see the following:
- Write down (COM10) (yours may be different, just write it down)
- Open up QPST
- Select Ports & Add new port...
- Enter your port (mine was (COM10) so I will put "COM10" in BOTH boxes)
- In QPST select Start Clients and RF NV Item Manager
- In RF NV Item Manager go to Settings -> Comport
- Select your port from the drop menu and press ok
- Under "File" choose Read Supported NV RF Items
- From the list of items navigate to number 550
You will see 9 text boxes. This is where you will put in your IMEI. It's weird how it's ordered so follow this EXACTLY. You will need to enter your IMEI from left to right, but backwards. Here's what I mean:
***Make sure the Hex box is checked***
EXAMPLE: Say your IMEI is 954091051099226 The boxes would look like so: 8 (This must go in the first box) 9a (The "a" represents the fact that the last pair only consists of 1 number) 45 90 01 (this can be written as 1 as well) 15 90 29 62
- Once you enter in the data, press Write NV
- Reboot your phone (remember to put your phone back to MTP + ADB by dialing *#7284#)
Your IMEI is now back!
Nice work going through all that
- I don't see "Ports (COM & LPT)" in Device Manager. Where is it?
Some of you may have trouble, even after dialing the correct numbers and that's okay. Here's what you need to do:
- Open up cmd as Administrator
- Type hdwwiz.exe to start the Hardware Wizard
- Follow the onscreen prompts until you come to two choices
- Select Install the hardware that I manually select from a list (Advanced)
- Scroll down until you find Ports (COM & LPT) and select it
- Add your phone's ports
- Now go into Device Manager on your computer and start from instruction #10 in the first part of this guide.
- Any news on fixing _______?
If there are any developments, I'd be posting about them on Twitter
- I like this a lot. I want to donate to you.
Thanks for the consideration, but please donate to Peoplearmy instead. He is the main mastermind behind this.
If your previous phone was only capable of 3G - remember we had to dial *228 to activate it or update our PRL? Well, DO NOT dial this on a 4G phone. Constantly dialing *228 on our Galaxy S3s has the potential to fry the SIM cards rendering our phones useless. With 4G phones, the PRL is automatically pushed to the phone via the SIM card and should be given periodic updates by Verizon.
