Para two :
please advise, whether if if Board Id &Software version/s are same ,
if the Bootloader(CFE)is different the FW upgrade cannot be used.
Never noticed the importance of this change, even if the FW version is same.
My understanding, it will work but some new instructions , may not work.
( say settings for client tr_069 , DDNS etc ).
Please correct if I am mistaken. Thank you.
I not sure dude if CFE is different what the result will be..u can try it out and let us know..but remember that u are always running the risk of a dead modem which is ok if u have a rented one
