Y2Linux Baseline 49

Y2Linux Baseline 49 — ready-made images for a first install, and the update for players that already run Y2Linux.

Already running Y2Linux (46 or later)

Settings → About & Updates → Check for Updates → Download Update → Restart and Install. Your Wi-Fi and Bluetooth firmware is kept automatically.

New install (from stock)

You need SP Flash Tool v5.2032, a USB cable, this release's Y2Linux-49-first-install.zip and the Innioasis Y2 firmware package v3.2.0 from Innioasis.

1. Unpack the Y2Linux zip and the Innioasis package.
2. SP Flash Tool → Download Only → load MT6582_Android_scatter.txt from the Y2Linux zip. Exactly BOOTIMG, RECOVERY, ANDROID and USRDATA are ticked.
3. Click Download, connect the switched-off Y2; wait for the green tick.
4. Unplug, press Power: Y2Linux and Reborn start.
5. Connect the Y2 to the computer again and copy system.img from the Innioasis package to the Firmware drive. The player takes the Wi-Fi/Bluetooth firmware from it and turns the radios on.

What's new

• No proprietary MediaTek firmware in any image. Each player uses its owner's copy (kept across updates). The system images of releases 46–48 were removed because they contained it.
• One-time flash package with the Y2 recovery image; afterwards everything updates over Wi-Fi.
• Bluetooth codecs: SBC, AAC (fdk-aac-free, AAC-LC) and LDAC.
• Headphone load measurement and two CS43131 driver fixes (thanks @samanz, #38); covers that load reliably, A–Z sorting that ignores case, accents and "The", genre titles on the album grid (thanks @samanz, Y2Reborn #6–#8).
