    Default Calculator for Band NR5 Qualcomm and NV Item Documentation

    Hello everyone, tell me no one has a calculator for calculating 5G Band in cells
    Code:
    /nv/item_files/modem/mmode/nr_band_pref
    /nv/item_files/modem/mmode/nr_nsa_band_pref
    And just in general, is there somewhere a description of all the cells that can be in the phone, I downloaded all the item files that the phone theoretically supports.
    But QXDM does not know all of them (which byte is responsible for and what). Some old commands could be understood by the source code of the modem (2014 year), but now new commands are coming out and it is difficult to understand them, especially when they are also disabled


    Basically, all the items from these files are of interest:
    mmode.conf
    nas_mm.conf
    lte_rrc.conf
    wcdma_rrc_external.conf
    geran.conf

    efs config Samsung S20 5G Qualcomm.rar

    It's simply works the same as lte_bandpref
    eg:for Band 41
    QXDM value:1099511627776
    binary:10000000000000000000000000000000000000000
    But the value range is limited to 64bit range so another 65_128 file will needed,I guess same for the NR

    It seems to me that something is wrong here, I have an SM-G9880 phone.
    According to the site https://www.techwalls.com/samsung-ga...8-differences/
    I must have bends
    5G Sub6 FDD: N1 (2100), N3 (1800)
    5G Sub6 TDD: N41 (2500), N78 (3500), N79 (4500)


    But as you can see, something is wrong here,
    1831657674385623 ____ 1_64 bits
    4193891 ____ 65_128 bits
    31 ___ 257_320 bits
