#04 - How To Get The Firmware - Hardware Hacking Tutorial
ฝัง
- เผยแพร่เมื่อ 5 เม.ย. 2020
- If you are struggling to get the firmware out of your device, this is the video for you!
In this video I will explain the possible ways we can use to to get the firmware of our IoT device.
I will do a practical example, of one of these possible ways. I will connect the PC to the UART of our sample device, I will analyze the boot log, I will access the command line interface of the boot loader, and I will dump the firmware, exploiting the dump command available in the boot loader. I will use a couple of scripts, do dump the entire EEPROM in an hexadecimal ASCII text file, and, then, to convert back this file in binary form to get the exact image of the EEPROM.

You sir are a human university, the best tutorials ever made, the most comprehensive and clear, keep up the good work, I am waiting for the next video in the series.
Hello Mihai Felseghi, thank you very much for your appreciation and support.
@@MakeMeHack Thank you for your Video, I need help! :( I think all my Devices have a malicous code, Smart TV, Monitor, Smartphone, Computer, Tablet, Xbox one, PS4...... They are all like radio controlled, they will be very fast hot, the sound will be quieter and quieter and the picture quality is worse, dark picture, even die Mini DAB Radio in the Kitchen have this malicous code, do you know about this malicous code?
Valerio, I really like the way you explain - detailed, clear and comprehensive, no shortcuts, no hiding details. Thank you for sharing your experience to us. I just discovered your channel, already subscribed and can't wait to watch from the beginning. Keep up the good work, I am sure this channel will grow up quick. (Y)
This was a fantastic video - you have clear depth of knowledge, and you present better than almost every other hardware reversing video.
I particularly like the context you give. So often presenters just show a wall of cryptic commands and output. You do a fantastic job in explaining.
This showed up in my feed today. I have no need to do any of this but I watched the entire video. You explain everything so well I just kept watching. Good job man.
Fantastic video's, the density of information is incredible to me!
Absolutely loving this series, and particularly this video so far, there are so many things I always wondered about in boot logs that you have addressed, it's inspiring me to learn more about all the other bits in there as well!
I am totally loving this channel. Thank you for spending the time and effort sharing your knowledge. I have so many of your videos to watch!
I am a programmer at a finance company, but was always interested in hardware, mostly from a software perspective. I started looking at this series about a year ago and it kick-started a burning interest in electronics and hardware hacking in general. Now my desk is overcrowded with bread boards, several chips and boards like raspberry pies, several arduinos of different types, standalone mc chips, avr and arm cortex and have started soldering stuff together with sensors etc etc. The wires are every where. Even spreding out to the living room! Now I have started looking into openocd and things to get to the bottom of the hardware communication things, saw this video series again and this time I understand wth you are explaining (in terms of technology) which makes me appreciate the video series even more. Grazie mille!
like i said in my tweet earlier today, this whole series is awesome. you fill in the blanks on a lot of information that is all over on TH-cam but not i none place. thank you.
Hi murrij, thank you very much for your continued appreciation and support.
Valerio, a genuinely informative video, packed with useful, advanced information that will inspire and spark the interest of tinkerers, young and old, everywhere. We all thank you for sharing so generously. For the feedback you asked for, I would encourage more use of text to display names and acronyms, because you naturally have an endearing strong accent and this could improve the clarity for a wider audience. I will definitely be learning from more of your videos. Subscribed.
This is perfect channel for all beginers in reverse firmware education and understanding what firmware works...Great job! Maybe in future we can send you some firmwares and you can make video from firmware analys this firmware.
Fantastic video production. So fascinating. You did a great job. This was easy to follow and packed with so much info.
Just fascinating
Ciao Valerio! You have the most instresting channel I've subscribed in my whole life! Keep the good work and stay safe.
I was all smiles during this entire video. Your expertise shows through and this was the exact content I was looking for. I am excited to learn more. Thank you!
😂 me too. God bless him
Great job, you're the best explain this topics... thanks for sharing your knowledge...
I teach this content and really appreciate your detail and precision! Pure gold!
thank you very much for your detailed video script series sir. very useful and im grateful to you
Mr. Giampietro, thank you for sharing your knowledge! You have some serious skills! I will share your material with my colleagues!
These series are gold... AMAZING
This is just GREAT stuff, Valerio! Grazie mille from Germany!
Am really enjoying this video series, thank you! I also am an old man who learned Perl :)
Hello sir I would really want to thank you for your awesome content! It's a real wealth of high quality hands on information coming from experience which you dont see often. Most of the time people make 1 short tutorial and thats itl. Also your english is very understandable and I would dare to say that its easier to follow than some native speakers. You really make an effort to speak clearly and it helps!
Have you maybe thought about doing a patreon or something like that? I really hope that you will contineau producing videos!
I already loved binwalk, and I had no idea it could tell you about the entropy too!
this is the exact content I was looking for. Thank you. God bless you
Man I wish you were still making videos you are awesome thanks for what you did make.
I have watched most of your videos and what can I say is your videos are fantastic and very informative. I am too an electronic engineer and I'm trying to reverse engineer a set top box these days. Your tutorials were very much helpful for me. I'm currently trying to extract the firmware using JTAG since I have successfully identified JTAG port using your tutorial. Keep up the good work!
P.s- you have a nice accent too ;-) I like it
Good for you, i am too electronic engineer
What JTAG did you use?
Grazie mille per aver menzionato Expect! Era esattamente la lingua di cui avevo bisogno. Ti auguro il meglio!
your video is gold, it slowly teaches me so many valuable knowledge, thank you so much. I feel luck to see your video even for the first time.
I have always wanted to get into hardware hacking. This video is great I hope you keep them coming.
Hello Isaiah Newman, thank you for your appreciation and support. I plan to continue with this series and with this channel. My original ambition was to release a video each week, but in reality, I need more time, so, on average I will release a new video every 10/14 days.
Sir, please, continue this awesome work!!
Subscribed, things like this is not only good to know, but can help you "modify" certain hardware..
I agree with the comments here. Thank you so much for sharing such amount of knowledge, in such a structured and brilliant way. We are lucky to have you. Gracie mille, from France.

Definitely deserves more subs! Grazi!
Fabulous video on first principles
Amazing! You are genius, my friend, i'm gonna watch every your video! ❤❤❤
Thanks a lot, this is pure gold
Loving the content, thank you!!!
Thank you and you gained another subscriber, I would like to change the firmware of an Epson printer, but I don't know if it's possible, just looking to find out
Great Tutorial, pls keep it up. Your are a very good tutor.
Great ,information in the video....keep it up make those wonderful videos..
Maestro mille grazie di Germania por cet seria di video informativo. It was very nice to see in practice things having thought about theoretically. As a thanks I will subscribe your channel for the first time after watching non stop 15 years TH-cam videos.
Great video. I am inspired to try and dump the firmware of my electric skateboard
Hello Jacob, thank you for your appreciation!
dude that would be cool.
A lot of thank for this useful guide. You are great!
Excelentemente EXPLICADO,!! gracias
great explanation, love you man. .
You are simply awesome, I hadn’t any idea how to do this and luckily I found you (seems most OpenWRT based routers uses same bootloader structure), I’m very happy to see how you manage your videos/explanations, it denotes you have passion for you work. This is great sir! :)
Hope you are safe under these rare days, take care good man!
Hello Gerard Fuguet, thank you for your appreciation and support. And yes I and my family are safe, at home 🙂
Holio molio this is such an amazing guide. Leave it to a real engineer to know exactly what they're doing!
You are a genius. Keep making videos!
wow that is amazing, i have question is it possible to read not only eeprom but the whole BOOTloader and for example if we change the MCU to be available to reprogram and the device to work fine. (i mean to transplant new Microcontroler which is empty )
So very very useful. Thanks for sharing 👏👏👍👍✌️✌️
Grandeee esattamente cosa voglio imparare ❤️❤️
bellissimo video mister!
you ae awesome you should of kept making videos
Отличный ролик! Время обновить инструменты!
May I ask you a question: where is stored the UUID in a board? In the EEPROM? Is this usually a hash?
Muy interesante la forma de codificar la informacion el los ruters desde el firware.
Very interesting and detailed information
讲的很好。
🙂
Thanks for the video. I am currently trying to gain access to a system through UART. However, when I connect my UART-USB bridge, I can only see the output of the device (so baud rate seems to be correct) but cannot send any commands. I have checked the wiring and settings. Both TX and RX are connected to the MCU (I checked the traces). Do you have any idea other idea?
Thank you for share the World so much knowledge, is impressive you domain, congratulations!!!
You are a young excellent man.thanks.
I am also an old man.... I haven't seen Expect or TCL for many years.... Expect was ("was", no..... "IS") wonderful for this sort of thing.
In the past I ran "end of day" on our mainframe using something very much like expect and my manager thought it was "black magic".
I want to go back and look at my old TCL scripts now.
Just in case someone stumbles upon here: uboot often has the commands to dump the contents of any connected SPI NOR or NAND flash disabled. Also, e.g. Xiaomi likes to disable UART-input entirely for uboot and the installed OS, so none of this will work in that case and you will need to either access the flash directly, use JTAG or find a vulnerability for the installed OS that lets you get root access that way.
A very helpful video...
very good content! thank you for sharing
Instantly subscribed. 🖤 ^_^
great explanation! Thank"s
Very nice video you might have started a passion for hardware hacking ❤
The dump is easy to reverse engineering intro would be awesome 👌
Re: TSOP (at 7:31) - there are clips for chips like this available. They can be found by searching for something like "nand tsop clip" or "360 clip". Security researchers use them to find TOCTOU (etc) firmware security flaws.
You can get tsop 48 clips, people used them before for Xbox 360 and ps3 etc but it’s not hard to remove one to read it and solder it back on the board
@@ImranAli-rp4kdcan you please provide any tutorial/video showing how it is done?
@@EvilSapphireR I’ll try to do that
@@ImranAli-rp4kd thanks man!
Sono indiano e adoro il tuo tutorial.Grazie mille!Mi iscrivo immediatamente! google helped me!
You are a perfect teacher !!!!!!!!!!!!!!!!!
10/10 please dont stop CIAO !!!!
The video is 3 years old, but have you tried extracting the firmware of ssd drives, in order to access nand values, after a trim, which only clears the sector mapping table?
Thank you. What are the options when there is not much data in uart boot beside "ERROR" , will appriciate help
This man is a true legend
Awesome, are your videos are very useful thanks for everything!
Hello Klairm, thank you for your appreciation and support.
Bravo. Molto interessante
Great stuff thank you

Great Tutorial
zio fai prima a parlare in italiano che capisco meglio hahah
sei il migliore grazie per sti video
Hello Sir. I got a cable modem device. It has a black cable where one end of it is connected to the motherboard and the other end of the cable has an audio jack connector facing outside. Do you know which type of cable should I use to connect to this audio jack and my laptop?.
