- Outcome of the update:  SUCCESSFUL

- DSM version prior update: DSM 6.2.1 (DS918+)

- Loader version and model: JUN'S LOADER v1.03b - DS3615xs

- Using custom extra.lzma: yes (0.11_test)

- Additional comments: Tried update 6.2.1->6.2.2 (DS918+), which did not work. "Migrated" to (DS3615xs), using clean installation without loosing data. Select "Show as hdd"-option when flashing USB stick with RUFUS. Updated to 6.2.2, then 6.2.3

Hello i want to post my successful CLEAN installation of DSM 6.2.2-24922 Update 6 on the F2-220.

The things i have used:
-Jun's Loader v1.03b DS3615xs (LINK)
-Driver extension jun 1.03b/1.04b for DSM6.2.2 for 3615xs (LINK)
-Bios settings set to "Legacy"
-VGA cable to select USB Stick from Boot options

Steps:
-First edit the GRUB file with VID,PID,MAC etc
-Second, mount the second partition and replace the extra.lzma file from Driver extension mod
-Third, extract the zImage and the rd.gz from the DSM_DS3615xs_24922.pat file and place them on the second partition again
 

Edit:
I have tested the DSM 6.2.3-25426 Version and booted up nicely

I have followed the same steps but i have used the following:
-Same loader
-Driver extension jun 1.03b/1.04b for DSM6.2.3 (LINK)
-The zImage and the rd.gz from the DSM_DS3615xs_25426.pat file



 

 

it worked for my Terramaster F2-220, as well.

Thank you very much for providing the details.

My upgrade path:

1. I "migrated" from 6.2.1 to 6.2.2 (DS918+). After the upgrade, I was not able to boot any more, although the update was completed successfully according to the sun-log-files.
2. I flashed usb stick with 1.03b boot loader as suggested in your description. Changed extra.lzm and zImage and rd.gz from the synology pat-file.
3. When using RUFUS, i checked the option "show as usb hdd".
4. I selected the reinstall option in grub, then clean install of 6.2.2 (DS3615xs). Completing the upgrade.
5. Then, again having flashed the usb stick with the 6.2.3 files, did a clean install of 6.2.3 (DS3615xs). Completing the upgrade. 

Success

 

What really killed my nerves, was the problem that at first, I did not get to the GRUB loading screen.

On my screen, I did not get past GRUB - no interrupt possible, the boot process freezed.

 

To fix this, check the option in RUFUS "show as usb hdd" and change boot device priority in the BIOS to boot from the flash drive.

By default, the HDD-disks are selected as priority one.

 

Thank you all for your great work here.
