Now I have downgraded to 3xx for my Synology 101j because I found the 426 unstable.

This is my "8 step - how to do" manual:
It should be possible to use this procedure on all synology models - just use the correct files...

1) Extract the VERSION file:
First - I extracted the VERSION file from the synology_ixp420_junior_0368.pat file. I am planning to use the synology_ixp420_junior_0385.patfor the actual downgrade, so I use a firmware file which is older than385 - in this place it is the 368 file. I used WinRAR (ver 3.51) toopen the pat-file, which in fact is a TAR copressed archive file. TheVERSION file is placed in the root of the TAR archive. I extracted thefile to the public share on the synology 101j
(用winrar提取旧版fw中的VERSION文件，选择你想刷回版本的上一版本就可以了。然后在nas建立一个public目录把提取的VERSION放进去。)

2) Enable telnet.
Search this forum, or use this one:
http://oinkzwurgl.org/dl.php?file=syno-telnet-r3.zip
and then telnet to diskstation.
（开启telnet后在cmd telnet NAS IP.账号是‘root’密码是你admin账号用的密码。）
3) Finding files:
DiskStation> cd /
DiskStation> find / -name VERSION
./etc/VERSION
./etc.defaults/VERSION
./volume1/public/VERSION

4) Verify content of file:
DiskStation> more ./etc.defaults/VERSION
majorversion="2"
minorversion="0"
buildphase="3"
buildnumber="0426"
builddate="2006/12/26"

5) Replacing VERSION file:
DiskStation> cp /volume1/public/VERSION /etc.defaults/VERSION

6) Verify content of file after replace:
DiskStation> more ./etc.defaults/VERSION
majorversion="2"
minorversion="0"
buildphase="3"
buildnumber="0368"
builddate="2006/06/29"
unique="synology_ixp420_junior"

7) Downgrade firmware using the web-admin-tool:
- Logon via web-browser as user "admin"
- Go to "firmware upgrade"

The folowing information is now showing:
Model Name: DS-101j
Current Firmware Version: 2.0.3 - 0368
Firmware Date: 2006/06/29

- Browse for the old firmware pat-file (synology_ixp420_junior_0385.pat) and click OK

8 ) Restore system configuration:
Restore old configbackupfile under "System -> backup"
select restore and browse for your old configbackup.dss file.

Iguess this step is not very importent, but I did have an old backupfile(made with 3xx firmware), so I restored my settings with this backup.

That's it.
Done...!

The time for downgrade process was aprox 10 minutes.
