DID NOT WORK INITIALLY FOR ME
Win7 x64 | VirtualBox | Jun's loader v1.02a
I went from 6.1.1 directly to 6.1.4 and it bricked, loader seemed to load fine but could not find on the network.
Downloaded Starwind V2V and converted Jun's Loader v1.02b synoboot.IMG -> synoboot.VMDK using option "VMWare growable image" (went from 50MB to ~ 21MB)
Removed old synoboot.vmdk from IDE controller, added new v1.02b, booted and found on network and got "RECOVER" option. Pressed recover, waited for reboot, about 60sec later I was back in business.
Msg me if you want/need my v1.02b synoboot.vmdk!
