[DS412+ USB flash module pinout]

Hello, I've found a shortcut for your situation in the meantime. With 7z you have seen what needs to be done. It is well known that many roads lead to Rome.

Here is the start:
1. Rename the downloaded .pat => .tar
2. Upload the new .tar to the DiskStation's general purpose share.
3. Installation of the synocli-file package from here:
https://packages.synocommunity.com/synocli-file/19/synocli-file.v19.f15047[apollolake-avoton-braswell-broadwell-broadwellnk-broadwellntbap-bromolow-cedarview-denverton-dockerx64-geminilake-grantley-purley- kvmx64-v1000-x86-x86_64%5D.spk
4. Now log into the SSH terminal and switch to root:
sudo -i
5. Then mount the internal flash to /mnt:
cd /dev
mount synoboot2 /mnt
cd /mnt
6. The newly installed package includes the Midnight commander.
Call this with mc on the command line.
7. F7 create a backup directory, let's say it says:
DSM6.412
8. Now switch to the new directory target in the right-hand window of the commander (left-right change with TAB).
9. Back to the left and use F6 to move the four files to the directory on the right.
03/18/2021 07:42 2.007 checksum.syno
03/18/2021 07:42 55 grub_cksum.syno
03/18/2021 07:41 5,859,308 rd.gz
03/18/2021 07:41 2,960,352 zImage
10. Switch right and get the new files:
Change through the directory tree to the .tar and open it with "ENTER".
Copy all four files there to the flash module (/mnt) with F5.
11. Leave mc with F10.
12. back to /root:
cd /root
13. Remove the integration from the flash module:
umount synoboot2
14. Done and reboot with:
reboot
15. Complete the migration of the DiskStation from DS412+ to DS713+ with the manual installation of the .pat (rename .tar => .pat beforehand) in the Synology Assistant.

 

Good course!

Huge thanks to DSfuchs would helped me to get my 11 years old DS412+ running on DSM7. Everything is fine and my NAS is now ready for another decade !

Thanks a lot DSfuchs, indeed the umount is important ! I'm sorry but I can't find "synology boot" on german ebay (I'm assuming this what you mean by "German bay") ?

Thanks DSfuchs. In step 5, you are also instructing to mount synoboot2 directly so this could also end with the next boot ?

I think I can avoid installing synocli and use mc in my scenario but I appreciate that you took the time to write a detailed procedure that covers all scenarios! Many thanks !
Indeed many roads lead to Rome  Still, I would be more confident to use a USB stick rather than directly replacing files on the original USB DOM.

Many thanks for your kind and precise response DSfuchs ! I already have ssh access to my DS412+, so I'm not sure why I need to install synocli ? (I can mount /dev/synoboot2 directly from ssh).

From your procedure, I understand that I just need to replace the 4 files by the one from the DS713+ PAT file (https://archive.synology.com/download/Os/DSM/6.2.4-25556) ? Ideally, I would like to test using a USB stick because I'm afraid to brick my DS412+ if I do something wrong (my DS412+ is a production machine :)).

Kind Regards,

François

Hi DSfuchs & 7up & All,

I would like to convert my 11 years old DS412+ to work with DSM7 and I'm reading this thread with a lot of interest.
Is there any summary of the steps needed ?

I currently understand that the following steps are needed:

1) Make a backup of the current synoboot USB device (this can be done using putty and "dd if=/dev/synoboot of=/synoboot.img")

2) Have a USB key with VID/PID = F400 (or buy a USB DOM)
   This is a challenging part as none of my USB keys (sandisk) can be used to "customize" VID/PID. 
    Do you have any pointer (amazon or other) to a USB key brand with a chipset supporting VID/PID change ?

3) Write the USB key with the previously saved image (synoboot.img)

4) Mount the USB key and replace the 4 files mentioned in step #35  (checksum.syno, grub_cksum.syno, zImage, rd.gz  from DSM_RS814+_25556.pat)

5) Then I need to do something using "vender 2 file with your SN/MACs and chk sums edited in exactly as described by DSfuchs".
     Do you have some precise instructions as I'm totally lost on these steps.

6) Finally, after removing the original USB DOM and plug in the prepared USB key, I should be able to boot DSM7 and get to the migration page

Is the above correct ? Many thanks for your help !
