Place it in your current working directory ⁃ Download mkifs_attributes.txt from github repo. cd to whatever the parent directory is to the ifs_extracted folder we made earlier ⁃ Place your patched MIBRoot into your extracted IFS location, overwriting the old MIBRoot. ⁃ Place a copy of /usr/apps/MIBRoot so it can be patched with IDA, Ghidra or similar Ensure files are present as shown in the terminal output ⁃ Issue "./dumpifs_helper.sh ifsroot_stage2_orig.ifs" to extract the IFS, your files will be in. ⁃ Copy dumpifs_helper.sh to this same folder. ⁃ Copy ifsroot_stage2_orig.ifs to some folder, open your terminal and CD to that folder. ⁃ Move to a linux computer with dumpifs binary (available from QNX SDP) ⁃ Cut and paste this block of data into a new file, name it ifsroot_stage2_orig.ifs In my case, this data was 15,639,040 bytes. ⁃ Select from 0xBA0000 to the end of the IFS, which is indicated by a block of padding "FF FF FF FF FF". If not, issue "flashlock" on PCM4 shell to obtain correct offset, target IFS is ~15.6mb. ⁃ Jump to offset 0xBA0000, ensure IFS magic of "EB 7E FF" is present. ⁃ Open downloaded RCC NOR image (PCM4_NOR.bin) in your favorite hex editor Unpack Root-IFS (if using downloaded image from PCM4) If you do this, you can skip steps 4.1 to 4.3**

RCC/ifs-root/*/default/ifs-root.ifs **Note: The desired image is the second ifs contained within this update file, use ctrl+f and find the second instance of file magic "EB 7E FF", your IFS image begins at this location and ends at the end of the file. ⁃ You can also pull this image from an update SD card at. ⁃ Remove SD card and insert into your PC. ⁃ Issue the following command to copy your existing FEC file: "cp /mnt/efs-persist/FecContainer.fec /net/mmx/fs/sda0/orig_FecContainer.fec" ⁃ Issue the following command to download your filesystem: "dd if=/dev/fs0 of=/net/mmx/fs/sda0/PCM4_NOR.bin". ⁃ Issue the "stfu" command to stop verbose logging to the terminal.

⁃ Open PuTTY, launch a serial connection to your COM port (see devmgmt.msc) - 115200, 8, N, 1 ⁃ To connect, you can remove the connector block from the quad-lock, then route your TX/RX/GND pigtails through the opening. ⁃ Connect GND to GND (PCM4 chassis works), RX on adapter to J5_TX on PCM4, TX to J5_RX on PCM4 pins B3 and B9. (available at pre-built for Ubuntu 19.04 圆4) Build these from source on your linux machine to ensure proper compatibility. ⁃ dumpifs and mkxfs from QNX SDP / OpenQNX. ⁃ Linux computer to unpack + repack filesystem
