II – Why I Cant Downgrade Ts-531P Series Firmware? How To Downgrade Qnap Firmware To Older Version?

Problem;

To Downgrade Qnap Firmware;

We use TS-531P firmware;
https://www.qnap.com/en/product_x_down/product_down.php?II=210 [^]

And TS-531X/TS-831X firmware;
https://www.qnap.com/en/product_x_down/product_down.php?II=260 [^]

Both fails via Qfinder & Qnap Interface.

III – How to Downgrade From 4.0.4 / 4.0.5 Firmware

Please try below steps to downgrade.

Warning: If any new storage pool or data volume was created on 4.0.4/4.0.5 Firmware, it will be lost after downgrade.

1. Download the 3.8.4 Firmware file from http://www.qnap.com/download

2. Unzip file and put file under Public Folder on Qnap

3. Connect to the NAS on SSH (download putty and login your Qnap)

4. Type the command:

touch /etc/ignore_degrade_check

5. Follow the wiki guide to manually install the 3.8.4 firmware:

[Two important checks]

(1) Please make sure there is /mnt/HDA_ROOT/update folder.

If it does not exist, create it using

# mkdir /mnt/HDA_ROOT/update

(2) Confirm no /mnt/update file or folder.

If it exists, you need to delete it using:

# rm -rf /mnt/update

if you get a message saying:

“rm: unable to remove ‘/mnt/update’: Device or resource busy”, unmount the folder and try the rm line above again. To unmount use:

# umount /mnt/update

After the above two checks, execute the commands below to perform the update.

1. Copy the image file to the normal update location:

   # mv /share/Public/TS-209_2.1.2_build1031.img /mnt/HDA_ROOT/update/

2. Create a link to the /mnt/update location:

   # ln -sf /mnt/HDA_ROOT/update /mnt/update

3. Run the update script:

   # /etc/init.d/update.sh /mnt/HDA_ROOT/update/TS-209_2.1.2_build1031.img

Note while the update script runs, you will get some output feedback in the terminal, similar to the following.

6. Results Should be like this. You must reboot Qnap device after this firmware upgrade / downgrade
