#22 Hack Your Electronics: Uploading Your Own Firmware to Any Device

Are you tired of being restricted by the firmware that comes with your electronic devices? In this video, I'll show you my own reverse engineering process, and how to upload your own firmware with the code that you've written to any device! Whether it's a router, a smartwatch, a toy, or even a random device!
You'll be able to take control and customize it to your heart's content. I'll cover the basics of firmware and provide step-by-step instructions on how to upload your code. So, join me and discover the world of your own DIY firmware!

Great video, always Nice to see the progress and steps when others are trying to reverse engineer stuff. Keep up the good work - would be great to see part 2 👍

[@makersfunduck]

Thanks 👍

[@Sierra-Whisky]

Awesome! I think I'll play this video quite some times in the future 🤓 Thanks!

[@makersfunduck]

Glad you liked it :)

[@annoniem1177]

I learned a couple of interesting things in this video, thank you! A second part would be interesting 👍

[@makersfunduck]

Glad you enjoyed it!

[@jjjjulian]

cool vid. also great tip with the gimp software!! thanks :)

[@makersfunduck]

Happy to help :)

How are disposable electronics not illegal yet?

[@makersfunduck]

indeed. it is a big problem for the modern society, and hope to see some progressive regulations about this issue worldwide.

[@flomojo2u]

Exactly, having essentially a complete controller, memory, sensors, and Bluetooth radio that's intended to go in the trash after 90 days is ridiculous and the ultimate in landfill abuse. At a minimum, they should be traded back in for a large credit towards the next device so they can be recycled.

[@user-ve7rv5zn8t]

Thanks for your explanation and I wait for the next video

[@makersfunduck]

You are welcome

[@campbellmorrison8540]

Wow that is a really informative video thank you. I doubt that I could actually do it myself nor could I write the code to make it do anything different but I now understand what is involved which is the level I like

[@AhmedEssam_eramax]

Amazing 🤩

[@makersfunduck]

Thanks 🤗

[@Subgunman]

Very informative! I would like to know if you could read what is in the board. It would be nice to have the ability to use these sensors as is for monitoring store rooms. It would be interesting to see if one could assemble a receiver cheaply for these devices. More than likely the manufacture has the high price on the receiver logger unit since the sensors are disposable. Batteries are easy to replace and one could easily fit a socket within the housing to make battery replacement a breeze.

[@mevk1]

I don't understand why that button cell battery can not be replaced? Just desolder it and solder in a replacement, no? BTW Very cool summary on modifying chips, sensors. All new to me. Complicated, to be sure, but fascinating. Now on to part 2.

[@makersfunduck]

it is indeed possible, but you need to have their subscription based app to be able to use it. I didn't have any of those.. also some manufacturers just blocks the firmware after battery gets empty.

[@tonyfremont]

​@@makersfunduckalso possible that the manufacturer stored some important information, like an AES key in RAM, making the device unusable after losing power. When Bluetooth is on, that device sucks about 20mA, but sleep mode is 1uA. It's an 8051 core too.

[@jfchebly]

nice

[@makersfunduck]

Thanks

[@happyguy058]

This verry cool, i am a beginner in reverse engineering. Do you have tips where to start?

[@makersfunduck]

my best tip is, find a simple device which works with a programmable MCU, and upload your own simple code on it. afterwards, write your own firmware (read sensors etc.). it is a fun process, and you learn a lot. you can also watch the second part of this video here: kzbin.info/www/bejne/pKrcnXybbdqan7M

[@happyguy058]

@@makersfunduck thanks great tip

[@dasWingo]

Part 2 would be awesome. Can you rip the original code from the device?

[@makersfunduck]

Now part 2 is ready :) kzbin.info/www/bejne/pKrcnXybbdqan7M

[@Z0RSY]

CAN YOU DO THIS WITH A WOOTING 60he

[@makersfunduck]

I dont have it. is it a cool keyboard?

[@aldob5681]

Of course is easier for an engineer to rev

[@Tntdruid]

So when do you hack a iPhone then? 😂

[@makersfunduck]

Which functionality do you think worths hacking? It is true that IOS limits users on many instances, so thats why there is a thing called "Jail Break" which removes those restrictions, and you can even install android on apple devices. but on that point, you can just use an android phone with the same specs, and would be happier :)

[@angryjoshi]

datashit :))))

[@makersfunduck]

So true.. Looking after the datasheets is the most trustable way:)
