Ultimate HackRF Portapack Mayhem Upgrade Guide

2023-2024 Edition

Introduction

When updating your devices, you may sometimes encounter problems that are directly related to the way you updated and to the changes that have occurred between your version jump.

That guide does not pretend to solve all the problems, some are real issues that have to be opened on the Mayhem GITHUB issues tracker.

On the other hand, if you have followed that guide and still have a problem, your issue have better chances to be solved as it will be possible to set aside common updates related problems.

List of important steps:

  • download all necessary files (it means at least SDCARD apps and firmware bin file !!)
  • have a reliable USB cable
  • ensure that your button battery is not dead, else use ‘PMem to Sdcard’ options in ‘Settings’
  • ensure that your CPLD is up to date (no need to update each time, but be sure at least once)
  • flash the firmware
  • update sdcard content (do not forget to update APPS if you’re manually refreshing !)
  • if you are having strange apps problems, try a factory default reset. It’s important to note that you will loose your settings and will have to set them back if you’re doing that step
  • always go and check the settings after the updates, we may have added things that changed the memory layout of settings thus messing them.

You may search each each steps details in the Mayhem GITHUB Wiki, particularly in the following sections:

GPT4 analysis by Two Minutes Papers

#GPT4 is so amazing that it is a little bit frightening.

But hey, you can pour it a book and talk… to the book, isn’t it amazing ??

Seriously, the GPTs are incredible and the futur is going to change for sure.

Good or bad, well, wait and see.

PS: I can only encourage you to follow Two Minutes Papers. That channel is just so good, with simple and quick explanations, even when it’s a heavy subject like GPT4

Spotify Linux: fix crash or bad window at startup

If ever at some points Spotify on Linux refuses to start or start with fucked up graphics, there is a high probability that it’s due to hardware acceleration and a pesky update.

Spotify isn’t that much of a GUI CPU hog, so you can start it with hardware acceleration OFF and make it work again, like this:

spotify –disable-gpu

Some users reported that they needed to use –no-zygote too, but it made it instable for me.

Some had to also use –disable-software-rasterizer. I saw no changes when using it.

#spotify #gpu #linux #crash

Nilorea Library is part of GitHub Arctic Code Vault

Just wanted to say that my own public repo for NiloreaLibrary is part of the vault, and a copy of it is in the archive located in a decommissioned coal mine in the Svalbard archipelago, closer to the North Pole than the Arctic Circle. GitHub captured a snapshot of every active public repository on 02/02/2020 and preserved that data in the Arctic Code Vault.
