CC3200SDK: Service pack update error SL_FS_WRONG_SIGNATURE

Part Number: CC3200SDK
Other Parts Discussed in Thread: CC3200, UNIFLASH

I am trying update the service pack on some old units which is running below software versions:

Host Driver Version: 1.0.0.10
NWP Version: 2.0.7.0
FW Version: 31.0.0.4.1
Phy Version: 1.5.3.3
Build Version 2.0.7.0.31.0.0.4.1.1.5.3.3

Device was able to download the  new signature file and new .ucf file but when i am trying to close the file getting  SL_FS_WRONG_SIGNATURE error. Same code is working fine if we download another service pack which is specified below .

Host Driver Version: 1.0.0.10
NWP Version: 2.5.99.4
FW Version: 31.1.4.0.1
Phy Version: 1.0.3.34
Build Version 2.5.99.4.31.1.4.0.1.1.0.3.34

Do we need to update any intermediate service pack before updating  service pack (CC31xx_CC32xx_ServicePack_1.0.0.10-2.5.99.4-Beta).
