Y2 Rockbox Safety Rules

Updated: 2026-09-06

Firmware installation can erase data or leave the player temporarily unbootable. Rockbox Y2 packages are device- and baseline-specific.

Never do this

• Never flash a Y1 package or another device's preloader/scatter.
• Never use a package for an unknown Y2 hardware or firmware revision.
• Never rename a Beta V2 archive to rom_y2.zip.
• Never use the withdrawn Beta V2 packages or

  InnioasisUpdater_Setup_1.1.2.exe.

• Never use Format All, Firmware Upgrade, whole-device erase, automatic retry,

  or a write plan outside the five approved Beta V2 partitions.

• Never disconnect or reset while a read or write is active.
• Never publish device-unique protected data or raw private evidence.

Before installation

• Back up internal storage, microSD, and the complete hidden .rockbox tree.
• Keep the exact official Y2 Stock 3.1.7 recovery package available.
• Verify the platform asset against SHA256SUMS.txt.
• Charge the player, use a reliable data cable, and avoid hubs.
• Close software that may claim MediaTek or Android USB devices.

Beta V2 accepted boundary

The only accepted assets are:

• Y2-Rockbox-Beta-v0.2.0-UPDATE-ONLY.zip
• Y2-Rockbox-Beta-v0.2.0-Windows-UPDATE-ONLY.zip

Both are 361,774,260 bytes with SHA-256 409DDB4D2D18111FB8C3AB619F10F04B916B6B2A3FC04D1D38011324563F326A.

The guarded updater may write only UBOOT, BOOTIMG, RECOVERY, LOGO, and ANDROID. It must verify the device and archive, preserve omitted/protected partitions, perform no automatic retry, and complete five-range readback verification.

After flashing

After the updater reports verified completion, unplug the Y2 completely, power it off if required, and press/release the pinhole once while unplugged. Only the next clean cold boot is qualified. Temporary artifacts or broken screen sleep on an updater-attached automatic boot do not replace this reset requirement.

Stop and recover

Stop on an identity mismatch, checksum failure, unexpected partition, timeout, write/readback failure, persistent boot loop, repeated wrong route, missing storage, or persistent crash. Do not improvise a retry. Restore only with the official complete Y2 Stock 3.1.7 recovery package.

Release evidence

A release requires deterministic packaging, offline validation, guarded physical installation on every public route, complete readback, functional and USB regression, saved-route tests, power/sleep tests, Stock rollback, and server-side download verification. Public summaries omit device identifiers and protected partition hashes.
