CoolReader 1.0.0 — OTA updates for Touch HD 3
CoolReader 1.0.0 adds website-hosted OTA updates for PocketBook Touch HD 3 (PB632), firmware U632.6.11.2001.
- Download immutable, numbered releases from https://pocketbook.nimbushub.eu/.
- Verify the package SHA-256 and embedded version before staging an update.
- Accept newer versions only, with model, firmware and stable-channel checks.
- Preserve settings, reading history, the last book and custom application assets.
- Recover interrupted directory switches and roll back a failed first application run.
Installation
Install this release once over USB. Previous FW6 builds disabled OTA and their launcher cannot install staged updates. Extract coolreader-touch-hd3.zip and merge applications and system into the reader's storage. Back up existing settings first and safely eject after copying.
For subsequent releases, connect to Wi-Fi and choose Settings → OTA Update. Keep enough free space for the download and staged application files.
Downloads
The attached install ZIP and matching source archive are identical to the versioned website downloads. SHA-256 sidecars are included. The engine version remains separate from the application release version.
Validation
All 13 ARM/QEMU regression groups passed, including OTA checksum rejection, package extraction, archive path traversal, missing binaries and version mismatch. Isolated launcher tests cover staging, preservation of custom assets and the last book, interrupted-switch recovery and first-run rollback.
Physical-reader OTA installation and restart have not yet been verified. Other models and firmware versions are unsupported by this OTA channel.
