    Guys, you are trying, but I get the impression that you are not familiar with the concept of iGO functioning.
    Simply patching software, in this case, is not simple. iGO does not have a retail edition. It is dependent on licenses in every possible way and at every level.
    Read [Only registered and activated users can see links. ].
    Meanwhile, with the advent of the Luna release, the situation has gotten even worse.

    I mean - whatever you do with the software, if you don't have the proper licenses and interact with them - nothing.
    ...try to read between the lines...
    Before asking a question, know it's already discussed here and at 99.9% is not unique. Use search.

    Many questions become very arduous, a lot of time chewed deja vu...Since we have lost all the year of work and effort, many people have no will to answer the same questions again. Me neither. Use a search, please.

    @Boki, I think tamper with the check that accept the license file.
    @Roedi perhaps, it's not to this thread
    The serach made is from 1D04F24 licennse/d_fingerprint.txt
    1E94A96 license/
    In IOS the string was license/%s. The more similar in the apk saw is license/%d. It is a "l" 00 00 00 "i" 00 00 00 "c" 00 00 00 and so on string. The size on IOS version tampered was 15mb and armv7.
    __text:004EAE90 ADD R5, SP, #0x28+var_20
    __text:004EAE94 MOV R4, R1
    __text:004EAE98 MOV R1, #0xCB066C <= ref "l" 00 00 00 "i" 00 00 00 "c" 00 00 00 "e" 00 00 00 "n" 00 00 00 "s" 00 00 00 "e"
    __text:004EAEA0 MOV R0, R5
    __text:004EAEA4 BFC R2, #0, #1
    __text:004EAEA8 ADD R10, SP, #0x28+var_18
    __text:004EAEAC BL sub_3A200
    __text:004EAEB0 MOV R0, #0x8140
    mine license/%s

    the check is some several bytes after in
    _text:004F3A80 loc_4F3A80 ; CODE XREF: sub_4F3590+4A4↑j
    __text:004F3A80 MOV R0, R8 ; void *
    __text:004F3A84 LDR R1, [SP,#0x80+var_6C] ; void *
    __text:004F3A88 MOV R2, #0 ; size_t size word #10 before patching it
    __text:004F3A8C BL _memcmp
    __text:004F3A90 MOV R2, #0
    __text:004F3A94 MOV R11, R0

    Send me a private mes
    sage and we can get in contact. The main idea will be to have the armv7 version and armv8 but start with the v7

    the version currently available for armv7 is as follows iGO Navigation v9.35.2.252289

    [Only registered and activated users can see links. ]

    the version for armv8 should logically be in the first post

    What interests me now is not cracking the software to use it with other licenses, but only to be able to either not depend on the two obb files, or to be able to hope for message # 22 from alcdl0 from consider bypassing somehow the checksum test of these two files in order to modify them to reintegrate them into the system, the question will be to know if it is possible to reconstitute a fully functional obb, or if it will be necessary to 're-sign' this file type as with an apk
