my record on upgrading from 4.1 to 5.0
Step 1: download gnoboot-alpha10.5
get it on http://www.gnoboot.me/ > Downloads > gnoboot-alpha-lastest-mirrorX
extract password: 6n0boot-AlpHaTen.5
Step 2: download DSM 5.0-4458 from Synology website
for release notes or China mirror site, go to http://www.synology.com/en-us/support/download/DS3612xs#download_tabs_dsm
Step 3: download & install Win32DiskImager
http://sourceforge.net/projects/win32diskimager/ -> download and install
select the *.img file and destination usb device, then press write.
*-ext2.img if you read/write in linux, otherwise *-vfat.img across multi-platform. -vfat.img modified time looks incorrect, but after image was written, its zImage modified date is 2014-04-04
Step 4: boot-up
(if applicable) connect VGA cable and keyboard to N36L
insert USB drive, boot up N36L (config BIOS if USB not 1st boot device)
select “gnoboot.me” in GRUB menu > “gnoboot-5.0-4458”
wait a while until “DiskStation login:” displayed
use Synology Assistant to lookup new IP address, double click to open web interface
Step 5: installation
follow on screen instructions, uploaded the downloaded DSM_DS3612xs_4458.pat
at the end, a warning will be display, about permission or serial number error. ignore it. deal with it after boot up.
Step 6: reboot
this time, select “gnoboot-alpha” on grub
It takes quite a long time for upgrade script to run, be patient and don’t panic.
At this moment, set static IP on router for new MAC address (screen from Synology Assistant)
When “DiskStation login:” displayed, new 5.0 can be used
Step 7: update and grant permission
Control panel >User, grant admin with all read/write access. re-create user if any.
Go to File Station > usbshare1 > boot > grub > meun_alaph.lst , right click, open with Text Editor
change from “kernel /zImage” to “kernel /zImage sn=B3JN12345”
Control panel > Update and restore > Download, click “Download” button
update 2 is important for OpenSSL bug (Heartbleed). Yet, meaningless if it is a home network though
ssh to Diskstation, as root, run
sed 's/flashupdateDeb/flashupdateDeb1/' /email@example.com > /firstname.lastname@example.org
mv /email@example.com /firstname.lastname@example.org
then go back to web interface and click Update once download finished. System will restart
Thanks for the guide.
The Step 7 for updating to 4458 Update 2 needs to be changed as 4493 has been released. Seems need to manually download and select 4458 Update 2 file.
Thanks for heads up.
Gnoboot seems inactive on development and there is another guy working on Nanoboot. I blog my upgrade process on http://18.104.22.168/2014/08/10/upgrade-gnoboot-4485-update2-nanoboot-4493-update3/
