[Lenovo Legion Phone Duel 2] VegasDon1:
So after looking everywhere for several months for someone generous enough to provide an original QCN backup file for my nonfunctioning Lenovo Legion Phone Duel 2 and having no luck at all, I decided to buy another **handset in hopes of helping someone out there who is desperately seeking to resolve the issue of having no cellular function and nondetection of equipped dual SIM cards.

Note: I have removed both of my personal **IMEI numbers for obvious reasons from the attached QCN backup file I have provided.

INSTRUCTIONS:

Step 1. Launch the Qualcomm IMEI Rebuilder aka "IMEIRebuilder.exe" application which I have included in the zip file that is attached to this How to guide below then click "open", now locate the QCN backup file "00000000.qcn" in the folder labeled, "Original QCN backup Lenovo Legion Phone Duel 2 12GB 256GB variant" which I have provided.

Step 2. Once the search window opens click on "00000000.qcn" then click on open then replace **IMEI 1: 111111111111111' and **IMEI 2: 222222222222222" with your original IMEI numbers then click on "REBUILD" and save your newly created QCN file to a folder on your Windows PC.

Note: If you have lost your original **IMEI numbers refer to your original box which should contain a labeled sticker containing both of your original 15-digit **IMEI numbers.

Step 3. Once you have completed steps 1 and 2, launch QFIL in "DIAGNOSTIC MODE"

This step is very important and necessary in order to restore your recovered QCN data back onto your Lenovo Legion Phone Duel 2 phone or Lenovo Legion Pro 2 so that you can send and receive calls again.

Step 4: At the top of the QFIL window click on "TOOLS", then navigate to "QCN Backup and Restore" a pop up window will appear then select "RESTORE". Please allow the QCN restore process to complete. Once it is done, simply power off your Lenovo Legion Phone Duel 2 phone and insert your sim cards then power on your **device. If done correctly, you will be able to use your Lenovo Legion Phone Duel 2 to send and receive calls again.

I do not own the Lenovo Legion Phone Duel 2 16GB/512GB variant so this procedure may or may not work for you but worth a try when there is little to no other solution available.

NOTE: The attached QCN backup file and instructions also apply to the Lenovo Legion Pro 2 (Chinese Variant)
