I want to make it clear that the following tutorial serves to restore the functionality of devices that do not make more calls, nor receive calls, as well as do not register on any network why the imei or efs folder is corrupted.

You will need:

  • A computer with windows 7 operating system;
  • A usb data cable in good condition (original preferably);
  • QPST Software;
  • HEX2IMEI software;
  • USB drivers from your device.

Get to work!

To check if the imei of your device is corrupted or zeroed just dial on the keyboard of the device the code *#06# check that the numbers that appear on the screen are the same as those behind the battery of the device, if there are divergences or if in place of the imei appear the message imei null or imei null then your phone is with corrupted imei.

Example of device with imei corrupted by unsuccessful update.

The first step will be to remove the back cover of the device, and the battery (if possible) and then write down the imei which is a 15-digit number that is behind the device.

Write it down in your computer’s notebook or paper if you prefer.  You can also find the imei on the sticker that has in the box in which the device came when new.

Also remove the SIM card and memory card from the device replace the battery again and then the next step will be to activate USB debugging from your device.

The second step will be to reconnect the device, and activate the developer mode in the settings menu of the device, and then also activate usb debugging. To do this just go to the settings menu of the device, and click seven times on the build number option as in the image below:

You must click seven times on the build number option.

On LG handsets you may need to go over the phone> Software Information > and you should click on the assembly number option seven or more times to activate the developer menu.

The next step is to use the developer menu, which is now active in the device settings to enable USB debugging. So just go to “Developer Options” and activate the options: USB debugging and if your device is a Samsung, you should also activate the “OEM” unlock option.

Turn on the USB Debugging option in the Developer Options menu.

After you enable the options in the developer menu, you may need to change the way the device is recognized on your computer’s USB port to DM+MODEM.

Enter the code *#0808#* on your device’s keyboard, and select DM+MODEM+ABD.

On Samsung devices you can do this by typing “*#0808#” on the keyboard,
and selecting “DM+Modem+ADB”.  If you don’t do this, qpst may not recognize the device! There are other access codes for the secret menu that changes the option of how the device is recognized, are they: *#8080# *#9090 #

Note: Do not forget as soon as you finish repairing the device back to the MPT option from the menu to have normal USB functionality of the device later.

The next step will be to install qpst 2.7 software on your computer.

Step by step installing QPST:

After you have downloaded QPST, install the program et al. on your computer by double-clicking the QPST_2.7.exe file, then inside the installer click Next>Yes>. Put anything in the “Username” and “Company” boxes then click Next>Next>Next until you install. And finally click finish to finish the installation.

The next step will be to install the USB drivers of your device on the computer, you can download the drivers of your device as the mark through the links below:

Select your device correctly from the links, download and install the USB drivers.

Identify on which port the device was recognized in device manager.

Enter the Windows Device Manager, and the device list open the COM and LPT ports option, view the listed devices. One of them should be handset, identify what it is, write down the com port number on which it is connected, as in the photo my device is an LG and was plugged into the COM3 port:

Your device may appear plugged into the COM4, COM3, COM2, COM5 port on the port on which it appears connected, to later configure the QPST correctly.

The next step will be to configure the QPST to recognize your device, do the following:

Open QPST Configuration in the start menu>programs:

Open QPST CONFIGURATION.

Open QPST Configuration with one click, and then click ADD NEW PORT:

After clicking add new port, a window will appear, like the one in the image below, just insert the USB port in which your device is connected in the fields: Port and Port Label:

Here I inserted COM3 because the port on which my device was listed in the winows manager was it. but remember to check in your manager.

Click Ok to insert the port into Qpst, and then click START CLIENTS > and click >RF ITEM MANAGER:

Click START (CLIENTS) and then RF ITEM MANAGER.

In the RF Item Manager window you need to click Setting and then on the Port Item and select again the port where your phone is connected:

Select the port where your device is connected and give OK.

Now, click the button with phone icon that exists at the top of the window on the left side, option Read RF NV items from phone:

Click read RF items from the phone and wait to load.

Next you need to click on the customized NV Item list option in the Option menu:

Select ITEM 550 from the list on the left and click the > button to import to the list on the right and click SAVE.

Right after clicking save in the following window, you must select ITEM 550 from the list and select the HEX option in the window as shown below:

The field where array is written < unsigned 1 by[0]e > is where you must enter the first two digits of the imei of your device, but calm!!  First you must convert the imei of your device to hex using the other little program you downloaded here, the: IMEI CONVERTER.

Note: Each comic,

< unsigned 1 bye >Array[0]

< unsigned 1 bye >Array[0][1]

< unsigned 1 bye >Array[0][2]

< unsigned 1 bye >Array[0][3]

It only supports two digits, okay!  Then you must insert two digits into each frame, only!

Open the IMEI CONVERTER with a double click, and insert your 15-digit imei into the ENTER IMEI box, and then click CONVERT IMEI!

In the converted imei box, this is where your imei already converted to hexa and ready to be inserted into qpst will be generated.

Enter the imei you converted to hexa starting with the first frame. Each frame can receive two Digits/digits. So put only two digits in each frame ok!

When you finish entering the digits in each of the frames, just press WRITE NV to realize the change of the data and ready, your phone has already returned to normal operation!

Remembering that it is good to restart the device to fix the settings.
