Its telling me to format my sandisk and then it says my sandisk memory card it protected and to change it and i dont know how to do that.

I think there is switching tab up and down at the side of your sd card.

1. Be sure that the device you are using the 4GB micro SDHC card for,
is able to use this type (HC=High Capacity) of memory.
2. Check the memory card is working well on a notebook / pc with an adaptor
and/or a SD-cardreader.
3. Format the memory card and re-check.

Most SD memory cards have a tiny slide switch on the edge of the card. Move this slide switch from Read to Write to turn off the write protection.

you've got to format the card... attach the card to card holder and then card reader to the PC... format it to FAT... this should remove any password protection...

It supposes to have a tiny lock/switch on the side. Move it up or down to turn off/on the write protection.

this happens when the card is corrupt replace it

it means that the memory card is protected by a lock code...try to find that or otherwise format it using the computer....
is this cleared your problem?

hey I just figured this one out dont know if it is a cowinkydink or what but on the adapter the big one it has a little slide you wont see it unless you look for it, its on the leftside, it says lock one way and unlock is the other. So I switched it to unlock and it seems like its downloading, I havent got the error message about the write protection yet and its still downloading, Try that and see if it works, Im gonna try mine and see in about 4 minutes. Good Luck!

there is a switch on the side of some cards. If it is a software memory protect than u need the program.
Otherwise u can do it by wiping everything off it with a reformat. make sure us are using the same format as is there (probably FAT16).
If that doesn't work get a partition manager program and delete and reinstall the partition and format is - make sure u get the RIGHT format

Re-format it. Put the SanDisk 2GB microSD memory card into your LG enV2 and format it from there. If that does not work plug it into your laptop then right click the icon and format it to FAT and click on default settings.
