Installation

The following steps are required to install a custom firmware:

1. Create a backup
2. Prepare the installation
3. Download a compatible firmware
4. Verify the integrity of the firmware
5. Install the firmware by using the web interface

It's necessary to create a backup of all data. Operating System upgrades are always dangerous. You should also create a backup of the configuration by using the web interface (System → Firmware → Configuration Backup).

Disconnect all existing connections (FTP, SMB, …). Deactivate standby features to prevent the NAS system to going to sleep.

All firmwares are complete (no deltas) and independent of the installed firmware. A downgrade should be avoided. Install a new firmware with a version number which is equal or higher to the installed firmware version number.

Firmwares are only compatible to their corresponding NAS systems. For example are N1T1 firmwares (3603.484) incompatible to N2R1 firmwares (1.0.0 2569). Incompatible firmwares might brick the NAS.

The downloaded file has to use the file extension .bin.

The integrity of the downloaded file should be verified. MD5 checksums are provided on the download page to verify the integrity.

Use programs like MD5 context menu (Windows) or md5sum (Linux) to calculate the MD5 checksum of the downloaded file.

> md5sum firmware_2557t_1_0_0.bin 
1fe5b3cbe65889665f2f67372b93d026  firmware_2557t_1_0_0.bin

Install the downloaded firmware by using the web interface (System → Firmware → Upgrade). “Tantalus' Firmwares” are always System Upgrades.
