What to know first

Windows PCUSB Writer is currently Windows-only.

Apple Silicon unsupportedM1 / M2 / M3 / M4 Macs are not supported.

First run onlineAn internet connection is needed for the initial login.

Shortest path: `Get USB Writer` → `Select Toolkit and create boot media in Writer` → `Boot target machine` → `Connect to network` → `Log in and reach ONLINE state` → `Start erase from masamune.ai/control`.

Boot media

Use USB 3.x with at least 128 GB. For multiple iOS devices, use a 256 GB or larger USB SSD.

Windows PC

Used to create boot media with USB Writer. Erasure itself does not run on Windows.

Target PC

Use x86_64 Intel / AMD hardware with at least 8 GB RAM. Use 16 GB for four-device operation.

Network

First login, cloud control, and iOS restore need network access. Wired LAN is recommended.

Multiple devices

The standard range is one to four devices. Four-device use is qualified for the specific PC, powered hub, and cables.

masamune.ai account

Prepare client code, staff code, and password.

Note: Apple Silicon Macs (M1 / M2 / M3 / M4) are not supported. Intel Macs remain supported. There is no macOS or Linux edition of USB Writer.

Confirm the operating environment

Area	Minimum guidance	Recommended configuration
Boot PC	64-bit Intel / AMD, 8 GB RAM	Four or more CPU cores, 16 GB RAM
Boot media	USB 3.x, 128 GB or larger	256 GB or larger USB SSD
Internal storage	Not required for Toolkit runtime	128 GB or larger SSD if Windows is retained for administration
Network	DHCP, DNS, and HTTPS access	Wired 1 GbE; Wi-Fi as a fallback
USB hub	Self-powered for multiple devices	USB 3.x, separate from the boot SSD, with short certified cables

Parallel operation: Our internal environment has completed seven iOS devices simultaneously. That is not a guarantee for every PC or hub. Customer environments are qualified progressively from one device using the same PC, hub, cables, and device mix.

Get USB Writer

Sign in to masamune.ai and retrieve USB Writer. USB Writer is the Windows application used to prepare boot media and retrieves the selected Toolkit version inside the app.

Open masamune.ai

Create the bootable USB

Insert the boot media into a Windows PC, select a Toolkit version in USB Writer, and write the media. Reuse it between runs. Online module updates can apply without rewriting; rewrite only when an OS-level ISO update is required.

Select Toolkit

Choose the Toolkit version inside USB Writer.

Select USB

Choose the correct destination drive.

Write and wait

Do not remove the drive until writing is complete.

Warning: Existing data on the USB drive will be overwritten during creation.

Boot from USB and establish network

Insert the bootable USB into the target PC, open the boot menu, and select the USB device. After boot, confirm that the machine can reach the network for first-time authentication.

Manufacturer	Boot key
Lenovo / Dell / Fujitsu / NEC / Dynabook	F12
HP	F9
ASUS	F8
Sony / VAIO	F11
Other	Use F2 for BIOS / UEFI and adjust boot order

Boot support: Toolkit targets BIOS (Legacy), UEFI, and Secure Boot ON environments. Secure Boot remains firmware-specific, so verify the exact loaner or deployment PC before use. Wired LAN is the safest first-run option.

Log in and bring the worker online

Enter client code, staff code, and password on the login screen. Once authenticated, the worker reaches ONLINE state and becomes available through cloud control.

Client code

Identifies your organization inside the platform.

Staff code

Identifies the individual operator.

ONLINE state

Confirms the worker can now be managed from masamune.ai/control.

Safety check: The boot USB is automatically excluded with a `[BOOT]` label, so it does not appear as a normal erase target.

Start erase and retrieve the work report

The recommended route is to use masamune.ai/control from another PC, tablet, or phone. From there you can select the worker, choose devices, assign methods, monitor progress, and later collect the PDF work report.

Remote management

Best for handling multiple workers and tracking progress in one place.

Local execution

Use the TUI `erase` command if local-only operation is required.

Work report

PDF, QR, and log output support customer-facing and audit-facing explanation.

Method	Best-fit media	What to keep in mind
NIST 800-88 Clear	HDD / SSD	A fast baseline for general reuse-oriented handling
DoD 5220.22-M	HDD / SSD	Useful where legacy overwrite expectations remain
ATA Secure Erase	SATA HDD / SSD	Uses drive-native hardware erase commands
NVMe Sanitize / Format	NVMe SSD	Provides fast hardware-level erase paths

Architecture: A Toolkit worker connects to `masamune.ai/control` through the cloud data layer. Commands flow browser → cloud → worker, and progress flows worker → cloud → browser.

Q. Can the boot USB be reused?

Yes. Online module updates can apply without rewriting. Refresh the same USB with Writer only when an OS, driver, or other ISO-level update is required.

Q. Can the boot USB be erased by mistake?

No. It is auto-labeled as `[BOOT]` and excluded from normal erase targeting.

Q. Can first-time use be fully offline?

No. The first login requires network connectivity. After initial setup, local-only operation can be considered case by case.

We can align Toolkit setup with your field conditions.

Whether you run on-site operations, multiple sites, or return-heavy workflows, we can map the right startup path.
