Converting ds1515+ into ds1517+ DSM 7.2

K4L0 · June 15

I compared the v7.1.1 files of the two dsm files.

The kernel image file is the same for both devices.
In the synoinfo.conf file 3 important things are different: PCI slot, number of LAN ports, configurable LED brightness

              1515+: enable_etron_ssc="yes"
                1515+: esataportcfg="0xc0" 1517+: "0x60"
                1515+: eunitseq="sdg,sdh"   1517+: "sdf,sdg"
                1515+: maxlanport="4"       1517+: "8"
                1515+: mem_max_mb="6144"    1517+: "16384"
                1515+: s2s_task_max="8"     1517+: "32"
                1515+: support_led_brightness_adjustment="no" 1517+: "yes"
                                 1517+: eth4_mtu="1500"
                                 1517+: eth5_mtu="1500"
                                 1517+: eth6_mtu="1500"
                                 1517+: eth7_mtu="1500"

There are a few more files that are not needed:

             /etc.defaults/extensionPorts
             /etc.defaults/sysconfig/network-scripts/ifcfg-eth4
             /etc.defaults/sysconfig/network-scripts/ifcfg-eth5
             /etc.defaults/sysconfig/network-scripts/ifcfg-eth6
             /etc.defaults/sysconfig/network-scripts/ifcfg-eth7

The 1515+ BIOS version number is M111, the 1517+ BIOS version number is M405.

The contents are different.
DSM update automatically checks and updates the BIOS if necessary. This should be disabled.
Do not update the 1517+ BIOS! It will lead to brick. Downgrade is not allowed.

The following actions are required for the mod:

Everyone should perform the mod at their own risk!

Download and unpack the latest 1515+ DSM 7.1.1 pat file.

root@test:/volume1/1# python3 sae.py -k SYSTEM -a DSM_DS1515+_42962.pat -d .

Change the version number of the bios from M111 to M911 (the important thing is that it is higher than M405)

root@test:/volume1/1# cp ./bios.ROM ./bios.ROM.orig
root@test:/volume1/1# echo "40B010: 39" | xxd -r - ./bios.ROM

Update the bios with the modified file

root@test:/volume1/1# ./updater -b .

Change the synoinfo.conf file to 1517+ for the device:

root@test:/volume1/1# sed -i 's/unique="synology_avoton_1515+"/unique="synology_avoton_1517+"/g' /etc.defaults/synoinfo.conf

Create a task that runs after every reboot with root privileges.
This script will check the synoinfo.conf file on every boot and rewrite the necessary values if necessary. The DSM update containing the flash update can be modified.

Then manually update to DMS 7.2 from the web interface using the DSM_DS1517+_64570.pat file.

Hello,

The mod DS1815+ into DS1817+:

Only the script is different the other steps are the same.

Create a task that runs after every reboot with root privileges.

Wondeful !!

I'm contemplating doing this mod on my resurected DS1515+ ( resistor hack + transistor and coin battery)

Did someone try to apply DSM7.2 update to such a modded DS1515+ ?

How about auto updates ?

What if a new BIOS file shows up in a future DSM 7.2 DS1517+ file ?

Many thanis

EC

Created an account just to thank you for this awesome tutorial!
It worked flawless, I scheduled the latest script from post 4.

Lets see when the first update arrives!

Thanks!

Please updated us regarding update experience ... Thanks

Thanks for this guide, I've gone directly to DSM 7.2-64570 Update 3 and it's working fine.

for any newbies out there, like me, I logged in via SSH with my normal DSM admin UN and password, the commands wouldn't work.

you need to be logged in as root, you can change to root with the command: sudo -i

ds_syno · August 17

Any change that you can provide a DS3615xs -> DS3617xs script so one can update to DSM 7.2?

xturon · August 27

can you make script for 2413+ to 2419+ ?

thanks!

infinityzx · September 11

Thank you for the guide @K4L0 it worked like a charm!

However, I'm having some weird issues now, it looks like some specific thing is not working!

I cannot enable quotes for file shares, even if my filesystem is BRTFS, and the "File Services" section is completely broken! It reports a red message at the bottom: Failed to load the required resources" and many things within this section are just not working!

Any idea?

I wanted to update my 1515+ to 7.2 as well, but I stopped modding the update when I saw your issue. Let me know if your issue is resolved. Thx!

K4L0 · September 14

I have no idea, I use several 7.2 modded nas and none of them have any problems.

infinityzx · September 15

@K4L0would you advise to re-flash the latest firmware?

Whatsek · Tuesday at 12:20 PM

I did the manual update to 7.2.1 today: no issues, all is working, NAS is still recognised as an 1517+

I can set quota`s for files shares if the filesystem is btrfs. Not on ext4.
