Hacking a Hotel POS Tablet - How Hard Could It Be?
Vložit
- čas přidán 7. 08. 2024
- A lot of dedicated sales hardware (POS, or Point of Sale) is made from standard consumer tech. Clem encountered a (former) hotel tablet on sale, and wondered if it could easily be repurposed for general Android tablet use. Without a normal USB port, he has to sniff the proprietary connector with an oscilloscope, perform a factory reset, and even break open the tablet to verify its pinout bit.ly/3bhB8Cb
Will it boot into a usable version of Android, or is it indeed custom locked-down hardware? Share your hacking adventures on the element14 Community! bit.ly/3bhB8Cb

ROFL.. when I saw 'POS', I thought you were calling a hotel's room tablet a piece of sh#$.. Did not expect it to be a Point of Sale system.
Woosh
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
You could try to use ADB while the device is booted in safe mode
Interesting idea!
watching experts fail is very encouraging for beginners
everybody has to start somewhere, and I'm not an expert in ancase of such devices, so its fair to say that what I experience would be typical for the most people trying this.
An expert might have abetter shot, but I like to stick more with Hardware than software...
Once you had USB figured out, you could have restored it using ADB by connecting it to a windows or linux workstation. You’d need to find a vanilla image that’s compatible with it.
No activity on the USB ports visible e. I think there must be some code activation or do in the software before it even gets active at all.
@@MAYERMAKES not sure if he tried it at the bootloader though, before the custom android shuts off access
I did a Lenovo one used in Gregg's in the UK . Works perfectly..
I tried the pressing android version rapidly on my phone and got some weird P animation that changes colors when you turn the screen. doesn't seem to take any input or anything. I took a few screenshots and a video.
It's likely a little puzzle you need to solve to get zo the game, they got more complicated from version to version.
@@MAYERMAKES It doesnt seem to respond to touch input. It animates on it's own and the only way to change colors on it is to turn my phone horizontally like I'm watching CZcams. If I pinch with two fingers like I'm viewing google maps the P zooms in and out.
@@coondogtheman sounds like a puzzle to me
Android Pie has that psychedelic P easter egg in it, I couldn't figure out what it was about -- maybe a Google search would be of use?
That's the problem with PoS systems ... They are hardwired with custom software that blocks everything they don't use ... Then, since this is a disposable model that requires a input device to access parts of the memory, the only thing you can actually do is just take the battery and save some things. Like you said, it's mostly e-waste at this point. They are cheap to build and customize to the client need ... Since this was going to be a desk unit, they put the bare minimum to work effectively. Just some ram, wifi antennas, a custom chip, screen, battery, that's it. Nothing more. It's a dumb device, made with cheap parts and just for that one usage. They are not buying ipads for you to see all the amazing services they have. It's just a presentation screen ...
I think it's not as bareb9nes as it could be, but certainly built down zo a price and very custom.
Point Of Sale or Piece Of S**t LOL
You can use that tablet as an alarm clock. 😀⏰
Another use!
Can you use it as interface to control raspberry pi? Like vnc or similar? Like accessing pi IP to control it
since i can connect to a network, if the pis has a webserver runnign sure I could.
So you can't find any firmware to work with this device.
Jep, nothing, the Android seems pretty custom.
@@MAYERMAKES Not really, legally the manufacturer should give you the sdk used to build the os, otherwise there should be ones floating around on the internet for the soc but the work needed is kinda wasted for such a device
@@_DSch "should" is the keyword.
@@MAYERMAKES That sucks. I was thinking you could use a custom firmware but you need a option to flash firmware from external source, I don't think this unit has this option even if you knew how to make a custom firmware rom for it.
Maybe find an old Android root exploit?
Install android over wifi with adb that it?
No access to NY port at all. And where zo find any compatible fW /OS? It's sadly not that easy.
can you connect adb over wifi/internet? E.g. WIFI ADB ULTIMATE and flash a custom from?
from=rom
Off I had a clue how to compile/ obtain a suitable rom.
Not being a software guy, I think you're going to be pretty limited in what you can do with it.
Yep, sadly I don't have the skillet for the software side yet.
You can at least salvage the battery.
I kept it in until I need it, but for sure at one point I might get it out when I need it fir a project.
geek boy
Can't help it
'POS' might not mean what you intend it to mean
Kinda
hate e-waste :S
Right to repair now!! And oorn hardware!
