cisco - troubleshooting - crs-1 - turbo boot - downgrade from 4.0.3 to 3.8.4

It is my first time to re-install crs-1. Actually I have to downgrade IOS-XR from 4.0.3 to 3.8.4 on crs-1. I tried to downgrade it by using install add/activate command, but not success. & Then I use turbo boot function to re-install the system from the beginning. There are several things worth to mention:

1. Downgrade 4.0.3 to 3.8.4 by using install add/activate does not work.

I can successfully added 3.8.4 to the router. However I am not able to activate it. I got lots of alarm:

Install operation 43 '(admin) install activate disk0:comp-hfr-mini-3.8.4
disk0:hfr-mpls-3.8.4 disk0:hfr-mcast-3.8.4 disk0:hfr-mgbl-3.8.4
disk0:hfr-diags-3.8.4 disk0:hfr-fpd-3.8.4 disk0:hfr-doc-3.8.4 synchronous'

2. To read a flash disk in the rommon of CRS-1, the disk have to be format in CRS-1. DO NOT format the flash disk in GSR & use it in CRS-1. I got the following message when I tried to read a GSR disk from CRS-1:

rommon B11 > dir disk1:
open: file "hfr-atafslib-m" not found
loadprog: error - on file open
cannot load the monitor library "disk1:%hfr-atafslib-m" from device: PCMCIA slot 1dir: cannot open device "disk1:"
rommon B12 >

Then, I tried to reseat the card. The alarm is a little bit different compare with the previous one:

rommon B10 > dir disk1:
open: read error...requested 0x4 bytes, got 0xffffffff
trouble reading device magic number
dir: cannot open device "disk1:"
rommon B11 >

It is about device magic number. I remember someone got this problem before.

Problem solved after I use the disk which is format in CRS-1:

rommon B1 > dir disk0:
Directory of disk0:

2      0         drw-     LOST.DIR
3      119093695 -rw-     comp-hfr-mini.vm-3.8.4
rommon B2 >

rommon B3 > dir disk1:
Directory of disk1:

2      0         drw-     LOST.DIR
3      119093695 -rw-     comp-hfr-mini.vm-3.8.4
rommon B4 >

3. The turbo boot process is time consuming. & The crs1 just not mentioning that it is running turbo boot. So, don't break the process.

rommon config:

rommon B4 > set
PS1=rommon
IOX_ADMIN_CONFIG_FILE=
BSI=0
MEDIA_FORMAT=
BOOT_DEV_SEQ_CONF=
BOOT_DEV_SEQ_OPER=
ReloadReason=1
?=0
rommon B5 > confreg 0x102
rommon B6 > TURBOBOOT=on,disk0,format
rommon B7 > sync

command to boot the correct vm file:

rommon B8 > boot disk1:comp-hfr-mini.vm-3.8.4

And then the turbo boot process start:

..
Fail to open file name disk1/comp-hfr-mini.vm-3.8.4
boot: booting from disk1:comp-hfr-mini.vm-3.8.4
