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

Create a backup

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).

Prepare the installation

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

Download a compatible firmware

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.

Verify the integrity of the firmware

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 firmware by using the web interface

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

Verify the version number of the installed firmware. An incompatible firmware might brick your NAS system (e.g. N2R1 → N1T1, 2569 1.0.0 → 3603.484)! When the version number schema is totally different, then the firmware is incompatible!

Really awesome software - though I just updated the UI to the new version, disabling the option to use your software. When will you support the new UI?

Hi There;

I have a N2B1 LG NAS, and unfortunatelly it has the latest FW from LG the v2660.

Have you got plans to release a version for that LG FW version pls?

Is it possible that there is a newer version of phpmyadmin? I am having troubles with enabling Simplexml! I need that for some programs on my webserver. For the rest I am verry pleased with this software of you!

N2R1DD2 | 2660 (OEM) | OldUI (currently) Would like to second jobu's request for a version of your firmware that is compatible with the new UI. I'm eager to try out your software and would love to see that there will be a version to work with the new UI.

Thanks for the hard work!

Hi there,

Are there any plans for future updates?

I've rather stupidly installed the new ui and now can't use my nas in a raid configuration. My fault, but if an update could remedy this, I'd be truly happy!

Thanks for all your work, and making it public.

Hi tantalus,

I would like to update PHP to the latest version. I would like to run TYPO3. Would it be possible to give some commands and info how to do it. Thanks in advance for your help.
