Hacking HELP: trying to use m3simply on ds-x using DS

[exar khun]

need some help.
i have 2 NDSL units - one using my old ds-x card and the other one using an m3simply card...
when i was trying to use the m3 simply card on the ndsl unit that was only using the ds-x card, my ndsl unit cannot read the m3simply card. but when i use an original ndsl game card, the unit can read the game. so anybody canhelp with my problem?

the reason i am trying to use the m3dsimply on the ds-x loaded ndsl unit is bcoz my ds-x card is not update to the latest firmwar and thus cannot play the newer games. i read on this forum how to update the software but it looks complicated.
if ever i do try it, is there a possibility that i can brick my ndsl unit?
are there any other ways to update the firmware? is it worth it to update the firmware?

you only download an updater, run it, and then copy a few folders on the card, what is complicated on that?

1. back up your apps and format card
2. download: http://update.ds-x.com/Ds_Xtreme_updater_v1.3.zip
3. unpack
4. run
5. download: http://update.ds-x.com/skin1.1.2.rar
6. unpack
7. copy on the card
