Converting ds1515+ into ds1517+ DSM 7.2

K4L0 · June 15, 2023

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:

Hello,

thanks for your Howto and your work.

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

Cazman · August 15, 2023

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, 2023

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

xturon · August 27, 2023

can you make script for 2413+ to 2419+ ?

thanks!

infinityzx · September 11, 2023

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, 2023

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

infinityzx · September 15, 2023

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

Whatsek · September 26, 2023

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.

Neogx · October 7, 2023

So as long term you can just manually update to newer versions without any problems ? I think one poster said about if the update file has a bios update how does that work does doing it manually not check for that??

IIRC, in first post explain bios patching from M111 to M911 ( This should prevent bios update during DSM auto update)

rava · October 13, 2023

I have a DS1815+ and just did the update steps. But have not updated dsm to dsm 7.2 because i think i have made a terrible mistake.

I read "Only the script is different the other steps are the same" so i did all of that. But now I'm thinking that I perhaps should have downloaded the ds 1815+ file instead of the ds1515+ file...

And should have changed the synoinfo.conf file to 1817+ instead of 1517+

I thought that i could do it all over again but i read "Do not update the 1517+ BIOS!"

What should i do now? can i still update manualy the dsm 7.2 file for the 1817+ or does the device now think its a 1517+ and im forever stuck at dsm 7.1?

rava · October 15, 2023

@K4L0Do you think i still can flash my DS1815+ with the DS1817+ bios after i flashed it with the ds1517+ bios?

I did a reboot of the nas and he still works and still thinks he still thinks it an DS1817+ according to infocenter.

Or can i just edit the synoinfo.conf file to 1817+?

( I have learned my lesson and will never flash during watching a football game :))

K4L0 · October 18, 2023

The 1515+ and 1815+ have the same BIOS.

Do the BIOS mod again. (If you already have the current version of M.911, it will not update the bios.)

root@test:/volume1/1# sudo python3 sae.py -k SYSTEM -a DSM_DS1815+_42962.pat -d .

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

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

Only install the 1817+ pat if the BIOS version is M.911!

If the DSM looks like 1817+, manually update DSM_DS1817+_69057.pat from the web interface.

K4L0 · October 18, 2023

Check your current bios version number:

cat /sys/devices/virtual/dmi/id/bios_version

If it is M.911, you can install the 1817+ pat file.

rava · October 18, 2023

okay, i did the check and at the moment it is still m.111

A little bit strange because when i did the bios flash it said the flash update was complete

I made a picture of it.

I will try al the steps from the beginning again and will not update dsm before it is on m.911

Edited October 18, 2023 by rava

rava · October 18, 2023

K4L0 · October 19, 2023

This is fine:

Current BIOS Model Name : MohonPeak
Current BIOS Version : M.911

You can see that it does not upload the 1817+ bios because it has a lower version number than M.911.
New BIOS Model Name : Avoton DS1817+

That's it, you can update the 1817+ 7.2 DSM from the web interface

rava · October 19, 2023

Thank you verry much!!

Its works like a charm

Converting ds1515+ into ds1517+ DSM 7.2
