3. Download an IMEI converter.
4. Get hold of a working qcn (I used my own which I know works in my other Note 3). Open the file by using Ultraedit/HxD and try to locate the IMEI. In my case it often starts with “08 8A…”.


5. Use the IMEI converter and input your true IMEI. Memorize the output.

adb devices
su
setprop sys.usb.config rndis,diag,adb
9. Now Enable Debugging and Connect Phone to PC . Restore the qcn file from step 7 by using QSPT. You click on QPST configuration and Go to “ports”. If your port isn’t already visible go to the device manager, look up the Qualcomm Diag port and add it. For me I believe it’s COM_XX. Now you click on “start clients”, then “Software download“. Tick the “Allow phone/file ESN mismatch”, locate your saved qcn file and start restoring it.
