Please include DS415+ model.

Hello,

Great job, as I don't undertsnd why Synology stopped upgrading DSM for 1515+
I am questioning about running the script.

Could you precise the associated risk ?

THanks a lot.....

Hello,

I have a question, can I undo this?
So I mean back to DS1515+, or is that no longer possible?
Thanks in advance for your reply.

Hi,

just a small feedback. Afer transforming my 1515+ to 1517+ it is not longer possible to use quickconnect or the synology DDNS service.

It seems the device can not be registered because the SN is not assigned to a 1517+.

This lead to the problem aswell that the AME tools can not be registered successfully (so Photos is not working properly).

I will try to undo the settings... lets see how to achieve that.

how can I flash the old BIOS file again? Do i need to make the old file an newer version then M.911 or is there any force command to flash an older BIOS version?

christian5555 · January 30

Ok i managed to restore the old bios version by faking a higher version number and installed the saved BIOS file M.111.

Unfortunately even after replacing the unique in /etc.defaults/synoinfo.conf it will be still reconized as 1517+ no matter what I does.

Even changing the unique to 1515+ while in reset mode via telnet, I only can install a 1517+ image file instead of 1515+.

EDIT: working now, you need to edit both files. /etc/synoinfo.conf and /etc.defaults/synoinfo.conf

Came here to say that this script probably bricked my 1515+, the first part of the script went fine, but after doing the update with the .pat file and rebooting it was no longer detecting 2 disks, then rebooted again from within DSM 7.2 I presume and then it bricked with flashing blue light. Removed disks removed power waited... nothing. Reading the script now I see thing like BIOS updates in it. Probably corrupted BIOS or something. Gonna have to look for another DS1515+ to try restore my programs and data. Not worth trying to go from 7.1 to 7.2 at all in my opinion.

UPDATE1

First part of the script went fine, but after upgrading to 7.2 suddenly my NAS detected disks 1 and 2 as 3 and 4, and all the other bays remained undetected. Seems something with hardware disk mapping is off. I am assuming now that the automatic script did not set my bios number to M911, and therefor the .pat file of DS1517+ updated my BIOS from M111 to M405, which is the version shown cat /sys/devices/virtual/dmi/id/bios_version

Leading me to this line in the opening text:

Do not update the 1517+ BIOS! It will lead to brick. Downgrade is not allowed.

Now it seems christian was able to somehow update the bios to an older version by tricking it. Will have a look into that.

UPDATE2

Using the opening post I was able to get back from BIOS M405 to BIOS M111 by renaming Bios M111 to M911 and doing the flash, after that all my disks are detected correctly again and I am still running DSM 7.2. If anyone ever encounters this, it seems my synology was not bricked by updating the BIOS to presumably the DS1517+ Bios (M405) but it detected disk 1 and 2 as disk 3 and 4. I suggest to not run the automatic github script and do it manually using the opening post.

I am trying to get my 1815+>1817+

I grabbed the sae.py with sudo wget https://github.com/K4L0dev/Synology_Archive_Extractor/blob/main/sae.py

I grabbed the 1815+ pat with sudo wget https://global.synologydownload.com/download/DSM/release/7.1.1/42962-1/DSM_DS1815%2B_42962.pat

I tried to extract it with sudo python3 sae.py -k SYSTEM -a DSM_DS1815+_42962.pat -d .

but I just get a pile of errors, starting with

Traceback (most recent call last):
File "sae.py", line 1, in <module>
{"payload":{"allShortcutsEnabled":false,"fileTree":{"":{"items":[{"name":"images","path":

ending with

Hello can anyone say if i can try to use the same as the start of the thread to update my ds1817+ to ds1819+ to update my kernel?

HaeNolMan · March 8

hello!
I upgraded to 1517+, booted up fine and used it well for a while.
But now I want to go back to 1515+.
QuickConnect is not working.
But the backup bios is wiped.
Is there any way to downgrade from 1517+ to 1515+?
Any advice would be appreciated.
Thanks.

Worked like a charm! Only challenge was getting the right .pat file, which i found here (https://www.synology.com/en-us/support/download/DS1517+?version=7.2#system ) for others that might have that issue. Big thanks to @prt1999

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.

Thank you very much, worked like a charm! I ended up using the automatic script that @prt1999made but that had your code in it. Upgrade went super smooth, only issue was i was trying the wrong dsm7.2 version updates. Once found, also that went fast and smooth. Thanks again.

idocinthebox · March 16

So if I want to run the automatic patch script where do I run it? SSH into the Synology then run it from the command prompt? or run a terminal program on the synology itself ?

I am sorry if this is a newbie question, I just don't want to brick my device.

Have you ever tried to reinstall your internal flash module as DS1515+ using the original image?

twinsen · 2024-04-27T12:10:35Z

"7.2.1-69057 Update 5" just released, how to update to it? Can I simply do it from GUI, or the scripts will be missing after that?

DSfuchs · 2024-04-27T19:17:54Z

In order for DSM 7.2 to be available to you, you need model modding on one of the following models:
DS1517+
DS1817+
RS818(RP)+
RS1219+
RS2416(RP)+

Take a look at this in the related topic:
