    Same issue as above - whenever I try to access the inbox, outbox, darfs, sent messages etc the message "operation failed" appears. I cannot sent message, but can make calls - not sure if I can recieve messages... Also cannot access any of the phones memories - neither the phone one or the memory stick.

    i have the same problem with my k850i too. no inbox, drafts, sent msg's "operation failed". I went to the sony ericsson website and used the update software which then told me I WAS upto date with their software.. hmm.. I am going to send my phone back to where I got it to see what they can do.. Also.. I am not receiving any text messages nor cannot send any. I suggest you tell your friends not to txt u because you wont be able to see them! grr :|

I suggest you to update it's software to latest version located on sony Ericsson's website.

Posted on Mar 30, 2008

There is an option in the phone to undergo a master reset of the phones memory, this will delete everything on the phone however the sim will remain untouched. This fixed the problem for me however it was a bit annoying and i reccomend backing everything up on your computer before hand.

SOURCE: k850i - operation failed for sms inbox and drafts etc

I have the same problem with the sms thing, what i did is master reset and choose reset all (prepare back up first). Just wait few minutes and for me it worked. But do me a favor, just email sonny ericsson and tell about this problem so they will start doing something about it.

Sony ericsson k800i states operation failed when i try to open games

Operation failed" is an error message that occurs when the phone has got a problem with it's GDFS. Your phone sounds like it's very poorly. You say you've tried a master reset? Can you tell me if that was reset settings or reset all? I had the same error message on my k850i when trying to get into my SMS inbox. A full master reset resolved it.Can I also ask that you remove the memory stick when you try a full reset and don't put it back in until you've tried the phone again?
You cannot get viruses on these phones, so we can safely rule that out.

Operation failed

This is normally a sign that the firmware is corrupt - back up the data in the phone to the memory stick, and then run the SE update service program on a PC and reinstall the phone software (if it says "you already have the latest firmware", then select "reinstall anyway")

The update service application is here:
