J4105 user here. In order to boot, you have to have the usb stick, no way to avoid that as far as I know. I failed to load 918+ for the hardware (keep crashing), but 3617xs does work.
- Outcome of the update: SUCCESSFUL
- DSM version prior update: DSM 6.1.7-15284 Update 1
- Loader version and model: JUN'S LOADER v1.02b - DS3617xs
- Using custom extra.lzma: NO
- Installation type: BAREMETAL - Asrock J4105
- Additional comments: REBOOT REQUIRED; Domoticz seems to be unstable under some situation, not sure if re-installation would solve the stability issues.
Again, hw acceleration needs a valid s/n. If you want to use it, you can buy a cheap or used synology nas even it is not the same model. No one will share their vaild s/n to you.
I am testing ds3517 with 6.17. In my case I found the 918 is not stable enough to boot with 6.17 DSM and my j4105 motherboard, however ds3517 seems to do pretty good jobs.
The transcoding in the DSM is powered by CPU, right? What if I have a gpu installed, is it possible to use the gpu for transcoding? Just a crazy thought...
