Guys and girls, the modem bootup sequence via the bootloader IPC transport is reversed ages ago by me for galaxy s2 and galaxy nexus. Take a look at the recent libsamsung-ipc and samsung-ril from replicant

Excellent! But how can we use it? (We need a binary or App that can actually connect to ATCoP from userspace. As far as I can see, the only such interface binary (modemctl.c) is just doing some very rudimentary On/Off/reset stuff.

...
void print_help()
{    printf("usage: modemctrl <command>\n");
    printf("commands:\n");
    printf("\tstart                 bootstrap modem and start read loop\n");
    printf("\tbootstrap             bootstrap modem only\n");
    printf("\tpower-on              power on the modem\n");
    printf("\tpower-off             power off the modem\n");
    printf("arguments:\n");
    printf("\t--debug               enable debug messages\n");
    printf("\t--pin=[PIN]           provide SIM card PIN\n");
}
...

We need an actual way (like ipctool) to send receive AT command responses.

In addition, it only works (AFAIK) on XMM6260 type CP/BP's and not on Qualcomm. It also seem to require some funky way of installing a new kernel...which would preferably be avoided. While at the same time being incomplete not supporting other features like GPS, 3D graphics engine and BT. At least according to your I9100 4.0 Status page.

Torrent for your XGOLD626_Modem_HackPack.7z

Torrent attached. Seed if desired.

I also have x-gold 626. And I send sequence AT commands into /dev/ttyACM0 and receive IP, GW, DNS from operator. Them I used ioctl codes for assign IP, GW and bringing up interface. But I dont pinging gw: destination host unreachable. What I need to do more? I used IDA for disasm libril-xgold.so.
