Guide to Reviving an Unused reMarkable 2 Tablet with Software and Sync Issues
Key points
- Correcting the device clock via SSH resolved initial cloud sync error 0.
- Manual restart of update services was needed to progress past initial software update.
- SSH over Wi-Fi is disabled in software version 3.22 and later, requiring USB for initial access.
- Instructions provided for re-enabling SSH over Wi-Fi after initial access.
Initial Device State and Challenges
A reMarkable 2 tablet, purchased in 2021 and unused for approximately four years, presented with cloud sync failures (error 0) and non-functional software updates. These issues prevented the device from connecting to cloud services or receiving necessary system improvements.
Resolving Clock Synchronization
The first step to reviving the tablet involved correcting its internal clock. Accessing the device via SSH, the `timedatectl` command was used to disable automatic time synchronization, set the correct date and time, and then re-enable NTP. This action resolved the initial cloud sync error and allowed the first software update to proceed.
Addressing Software Update Stalls
After the initial update, cloud sync produced a new error (HTTP 400), indicating the system version was still too old. The tablet updated only to version 3.11.2.5 and would not progress further. Investigation revealed that the updater service failed to retry after Wi-Fi and DNS were unavailable post-reboot. Manually restarting the `swupdate.service` and `update-engine.service` allowed the device to detect and install version 3.27.3.0, bringing it to the latest software.
Managing SSH Access Changes
Software version 3.22 and later silently disable SSH over Wi-Fi. To maintain SSH access, users must connect via USB initially. The guide provides commands to re-enable SSH over Wi-Fi using `rm-ssh-over-wlan on` or by dropping a marker file, ensuring continued remote management capabilities.
