Thanx for suggestion oxygen8.
Just wanted to report my findings after several almost sleepless nights playing with NAS....
As mentioned before I started with bricked CloudStor, then I replaced HDD and successfully flashed original firmware (CS-WX/1D Series 1.13-2.35). This worked but there was no DLNA feature.
Then with different options several times tried to flash Plex-edition (LS-WLX 1.71-3.66 Halloween), first time it looked like success - web interface worked, also ssh, mysql, php was OK, but then I noticed that HDD isnt recognized. After reformatting HDD and reflashing firmware, HDD was recognized.
Then after several days I noticed that after every restart NAS cannot boot - it enters EmergencyMode. Boot was possible only thru TFTP which wasnt option for other family members so I tried to flash just some parts (boot,kernel,initrd) from different firmwares (plex, Shonk,CloudStor) wihout success.
Then I flashed Shonk mod 1.71 from: viewtopic.php?t=23603
- modified Updater's ini files according suggestions from GreyPeter: viewtopic.php?f=77&t=29915&p=170881&hilit=0x00003009#p170881
- started Updater and in Debug dialog checked all checkboxes (Update: boot,kernel,initrd,rootfs; Config: do not check version, rebuild partition table, delete user data partition, force update)
Now I have on my CloudStor working Shonk's firmware mod from LS Series.
I can use SSH, SFTP, SMB and DLNA. Later will decide if I need LAMP web server or some other stuff.
Now some outputs.
