    Dear Daniel
    thank you for your amazing work, but would you please explain the advantages of OpenWRT to MikroTik router OS ?

    Thanks for this guide! I've got an RBM11G and want to place ROOter on it. Going by the post, it looks like I need a USB to serial adaptor, but I don't know where to hook it up on the RBM11G. Can RouterOS be replaced without needing the USB to serial adapter? Cheers!

      Yes. IIRC, all you have to do is replace steps 7&8 with holding the set button while you plug in power. After about 30 seconds the LEDs start flashing, indicating it is now attempting a network boot.

    Daniel,

    I've got a similar configuration (RBM11G + MC7455). The modem gets detected and works in MBIM protocol. I don't know what to do next - it looks like it works in direct ip mode. How to force it to work?

Sierra Wireless LTE Modem Guide: Automated Flashing of the EM7455/MC7455 with a Ubuntu Linux 18.04 LiveCD

I've written a bash script to automate the entire process of setting up any of the EM/MC74XX series modems (Generic, Dell, Lenovo). This assumes you have the Sierra card inserted into a USB enclosure.

This post is part of my Sierra Wireless LTE Modem Guide Series. If you prefer to skip the blog nature of these guides and just grab the bare features and commands, my GitHub repository will serve as the authoritative source for this entire series. Any changes or updates will occur there first.
From the script description:
- Only for use on Ubuntu 18.04 LTS LiveUSB
- All Needed Packages will Auto-Install
- Sets MBIM Mode with AT Commands Access
- Changes all models of EM74XX/MC74XX Modems to the Generic Sierra Wireless VID/PID
- Clears Band Restrictions and Places Modem in LTE only mode.
- Flashes the Current Generic Firmware as of 2018-07-18

Crossflashing the Dell PERC H200 and H310 to the LSI 9211-8i

There are many fine guides online for crossflashing the Dell PERC H200 and H310 to the LSI 9211-8i that they truly are, but sometimes you just want to flash things quickly and in a straightforward manner. This guide aims to achieve that with one word: YOLO.



I have made available a flashing package that, using said package, you can have the entire flash process done in under 5 minutes. This guide is based on files and previous guides by Tyler Woods and techmattr.

There are some caveats: This will not preserve your SAS Address. That said, the only thing you care about is it being unique, so it is automatically generated every time.You can only have a single HBA in your system at a time.It is unsafe and I would highly recommend against running this on any system with a built in LSI HBA.Given the previous point, you should probably run this on a normal consumer motherboard. I used an old Dell Optiplex 755.
How it works: The series of batch files perform the following commands:
