To bad #3282 # doesn't work on this phone. I am looking for way to get into the engineering menu to see what bands are actually active. You should be better off than I was, I was a little careless thinking I could just restore my QCN file if anything went wrong, but I did something to the GSM/UMTS frequencies on the QPST Programming app that rendered mine inoperable at the moment. Be careful that you do not try to enable more than you need or try not to enable a Band that the phone cannot open, as you could cause problems. Anyway you change the decimal number on that item to the desired one with the Needed LTE bands. I won't go into that here just look up a thread on XDA to help your self understand it better or read the manual/use google. They started at the binary set went to hex then to decimal. FYI-there is conversion that takes place from the what you see defined as the LTE bands. Copy that down in case you need to restore it. Ultimately the LTE bands are defined as a binary set converted to HEX and the final result is a Decimal which QXDM uses. The LTE bands are defined in that decimal number. If you are not familiar with binary/hex/decimal then I suggest you familiarize yourself on that too. There are other LTE categories but if I remember correctly this was the only one that had a value. Look under NV Browser > LTE > LTE BC Config. įrom there open QPST Configuration, make sure your COM port is detected and open QPST Software Download and make a backup using the backup tab to a qcn file and a xqcn file just in case.Ĭlose that program and use QXDM to edit the LTE bands. įrom there you should see in device manager the COM port show up as Qualcomm Diagnostics Port 9001 COM #whatever. Make sure all the drivers are installed.īoot your phone into factory mode using ffutool.exe (found in Assessment and Deployment Kit (ADK)) by executing this command. You need to download and install QXDM professional 03.12.714 and QPST version 2.7.460. Remember that editing/altering/changing EFS data on your phone can render it inoperable or brick it if you do not know what you are doing or make a mistake. I recommend you get familiar with the XDA forums for extra information and analysis before you try to do it though. I can however provide you the basic information so that you can try it yourself if you decide. Can you provide me direction?I cannot build a step by step guide on this since I do not know enough about this area of us it is very easy to permanently mess up your phone with these tools.
