Subway surfers on a vending machine payment terminal that somehow is in debug mode (the seller did not mention this fact, but thanks anyways lol)

Newer helios gen zebra devices have now also been unlocked by patching the bootloader signature check out and setting an automatic relock system to a very big number 😅 This uses the same concept as unlocking the quest VR headsets. Zebra lets you downgrade to a vulnerable bootloader!

So apparently the password for the zebra scanners bootloader unlock on the older atlas generation of devices is just hardcoded in the bootloader. With some help from claude i managed to figure it out, zebra_atlas. Could have even guessed that one tbh LOL Image credit: tamay_idk on the bird app

There are also tickets that have a HOLD or DELETED state. HOLD: IGNITE ($1,400): 300 FUEGO ($5,000): 200 PHOENIX ($25,000): 50 PROMETHEUS ($1,100,000): 8 DELETED: IGNITE ($1,400): 700 FUEGO ($5,000): 500 PHOENIX ($25,000): 1340 PROMETHEUS ($1,100,000): 0 (2/3)

Looking at the ticketing site for FYRE Festival 2 and i noticed it makes a request that returns a shit ton of data, turns out you can see how many tickets have sold. IGNITE ($1,400): 79 FUEGO ($5,000): 22 PHOENIX ($25,000): 6 PROMETHEUS ($1,100,000): 0 (1/3)

If there is anyone interested in messing with the playstation portal, dumps of a few different android rom versions (launch fw to current) have been made and are now on tadiphone. dumps.tadiphone.dev/dumps/playst...

So as it turns out, the Humane AI Pin has debug pins that provide a usb connection behind the moon on the back. Currently it stays unauthorized in adb because it requires a certificate to authenticate. But i think the team is working on removing that so everyone can access it!

Full android firmware for the facebook portal is now available on tadiphone thanks to a dev unit falling into my hands: dumps.tadiphone.dev/dumps/facebo... If you like to break android devices open, we need you! Facebook is slowly nerfing these devices without providing a bootloader unlock! 1/4

Btw this is like a worldwide licencing deal across tons of brands which use the frameo software on their (cheap) picture frames
100
Marcel @mgdproductions.com · 25/01/2025
The frameo app also checks for "Blacklisted hardware" which in this case means that there is either a mic or cam present. Frameo frames are not allowed to include a camera or microphone.
100
Marcel @mgdproductions.com · 25/01/2025
All frameo picture frames get assigned a licence before they are allowed to work, this also makes it more secure so no one can just read/send arbitrary pictures to the frames because every frame uses a unique licence key to encrypt its data
100
Marcel @mgdproductions.com · 25/01/2025
If you own a picture frame that works with the frameo app, congrats, basically all of them ship with root access out of the box as per the manufacturer instructions that i was able to obtain through simple subdomain scanning and html inspecting the manufacturer dashboard...

"Our device integrates GPT through a close collaboration with OpenAI, leveraging a specific API" Uhh no you are just calling the regular endpoints with the API key present on the device lol They also never acknowledged the security issue publically lololol

When you remove the passcode and are very quick at bootup, you can spot the "Phone is starting" android message on the Humane AI Pin Sorry for the horrible quality, this thing is very hard to film with a phone

What is this kiosk setting lmao

Marcel @mgdproductions.com · 30/11/2024
Including the fire hazard (and very reflective) egg case
The humane AI pin charge case, looks like an egg but metallic, very reflective and it is recalled because of a potential a fire hazard

The playstation portal is unable to sign into your playstation account / connect to a ps5 on firmware version 2.0.5 This makes the hack by theflow0 impossible to execute, even if you obtain a fw 2.0.5 device.

Marcel @mgdproductions.com · 13/11/2024
Android recovery on the Playstation Portal is still accessible after they blocked rebooting from fastboot, however there is not much you can do with it as adb sideload does not get recognised on the pc and most options fail...

Marcel @mgdproductions.com · 06/11/2024
What is the reason that this is STILL ON BY DEFAULT

Marcel @mgdproductions.com · 28/10/2024
TLDR: NFC cards can launch apps apparently, kiosk mode can be disabled from settings, rom is userdebug so root access by default, a code is available to escape without an NFC card needed. Also found the update url to download the entire firmware.

Not gonna unlock the bootloader but damn would it be funny (this robot is like a thousand dollars, i am not gonna ruin it like that lmao) I got to lend it from the teacher for a few weeks for a project, definitely gonna dump the apps and rom from it in the meantime, this is interesting

In the gallery it has all the pictures it uses for the eyes and also some Chinese screenshots including IOS? It has 12GB of storage, 2gb of ram and a MediaTek MT6750 CPU

This stupid ass robot needs wifi to program, the only way to connect it to a wifi network is through the app which is locked to a licence. Our school did not bother to pay for the licence. What now? Well, it runs android 7 and has adb exposed, so i just used scrcpy lol

Marcel @mgdproductions.com · 15/09/2024
Dev options, adb and oem unlocking are enabled but i am unable to do anything with it as it doesn’t do data comms to the device. Here are some pics of the board.
