thanks very much for your help!

 

Actually this method worked for me:

 

WARNING: you'll loose your configuration and installed apps!

 

1. create the syno pendrive from scratch (it's corrupted during upgrade)
2. create an ubuntu live pendrive
3. boot up linux and open terminal
4. sudo -i
5. apt-get install mdadm lvm2
6. mdadm -Asf && vgchange -ay
7. fdisk -l | grep /dev/sd
8. mdadm -AU byteorder /dev/md0 /dev/sda1 /dev/sdb1                 (and list all your first partitions of the disks)
9. mkfs.ext4 /dev/md0
10. now all your 1st partitions are formatted, reboot removing ubuntu pendrive and inserting syno pen
11. choose reinstall
12. use manual install and select last working PAT
13. wait....., and you'll be DONE (of course all apps and configs are lost, but data should be there)

 

THIS!

 

thanks @Rabby, this worked perfectly for me too
