This is the presentation-layer reset for the supplied Reborn Y2 UI Implementation Pack. It keeps the existing playback, media, library, storage, radio, power, persistence, diagnostics, and service architecture. Y2Linux was not modified.

Source and artifacts

implementation commits: bd28e10 (reset), c2ab6cb (wired-control audit), 404cb42 (radio-forget fix)
recoverable pre-reset checkpoint: 0a104dd
ARM target: armv7-unknown-linux-gnueabihf, Cortex-A7 hard-float
production SDK used: /home/luca/Dokumente/Code/Y2Linux/out/y2linux-reborn-audio-final/buildroot
production bundle: out/reborn-ui-reset-01/
checksum file: out/reborn-ui-reset-01/SHA256SUMS

The stripped ARM candidate binaries are:

File	Bytes	SHA-256
`armv7/release/reborn`	2,448,588	`feeed433ba44d4d57d865bfe7b4d845a098326ac2bf1fb19664443b4aa1d5ae0`
`armv7/release/rebornctl`	445,532	`77d5e93e53d89fe46f000c3b1f54eb09f445db0bcd516cc908de9753926b6f18`

Rollback binaries were built from checkpoint 0a104dd:

File	SHA-256
`fallback/armv7/release/reborn`	`5bc77f2109271fdf6b48c70b24a2d1a02ba06ac3da26b35f9b2086090509d21c`

The bundle contains eight deterministic 480x360 PNG previews and a manifest. No Y2ROOT image was produced because normal UI logic belongs in Y2Reborn and Y2Linux was intentionally left unchanged. QEMU runtime qualification was not run because qemu-arm is not installed on this host; physical installation and device qualification are pending owner action.

Manual SSH installation

This is a userspace replacement only. Do not flash partitions and do not alter Y2DATA. Use the existing owner SSH workflow and substitute its approved host, known-hosts file, and identity below:

cd /home/luca/Dokumente/Code/Y2Reborn/out/reborn-ui-reset-01
(cd . && sha256sum -c SHA256SUMS)

scp armv7/release/reborn <owner-host>:/tmp/reborn.ui-reset-01
scp armv7/release/rebornctl <owner-host>:/tmp/rebornctl.ui-reset-01

ssh <owner-host> '
  set -eu
  test "$(sha256sum /tmp/reborn.ui-reset-01 | cut -d" " -f1)" = 609329f4a932b5c6ee360392756a93de7e5cf0f82b396c8fb65cecd42314d6cc
  test "$(sha256sum /tmp/rebornctl.ui-reset-01 | cut -d" " -f1)" = 77d5e93e53d89fe46f000c3b1f54eb09f445db0bcd516cc908de9753926b6f18
  /etc/init.d/S05reborn stop
  cp -p /usr/bin/reborn /data/reborn/state/reborn.pre-ui-reset
  cp -p /usr/bin/rebornctl /data/reborn/state/rebornctl.pre-ui-reset
  install -m 0755 /tmp/reborn.ui-reset-01 /usr/bin/reborn.ui-reset-01
  install -m 0755 /tmp/rebornctl.ui-reset-01 /usr/bin/rebornctl.ui-reset-01
  mv -f /usr/bin/reborn.ui-reset-01 /usr/bin/reborn
  mv -f /usr/bin/rebornctl.ui-reset-01 /usr/bin/rebornctl
  /etc/init.d/S05reborn start
  rebornctl status --json
'

If the health check fails, stop Reborn, restore the two backups from /data/reborn/state/ to /usr/bin/reborn and /usr/bin/rebornctl, then run /etc/init.d/S05reborn start. The fallback binaries in this bundle are also available for a controlled rollback. No private SSH key is part of the bundle.
