Ventoid

Ventoid is an Android utility for preparing Ventoy-style USB drives directly from a phone.

It is built for users who want a clean, open-source path to writing a multi-ISO boot USB without using a desktop app for every change.

What Ventoid does:

- Detects supported USB mass-storage devices connected over OTG
- Requests Android USB permission only when needed
- Writes a Ventoy-compatible MBR or GPT layout
- Writes the Ventoy boot core and EFI image, including the x86_64 Secure Boot chain
- Formats the main data partition as exFAT
- Shows a concise install status and progress bar

Why it is useful:

- No root required
- No ads
- No account
- No analytics
- No cloud dependency

Important:

- Ventoid writes directly to the selected USB drive, so choosing the correct target device matters
- A working OTG adapter or powered hub is required for actual USB writing
- Device compatibility can vary depending on the phone, cable, USB bridge, and flash drive controller

Ventoid is intended for advanced users, repair kits, travel setups, and people who want a portable boot-media workflow from Android.
