I recently bought the Samsung Galaxy Tab 10.1. The very first thing that I generally do with my devices is to check for any firmware/software updates. So, that’s what I did with the tablet… Settings > About > System Updates > Update…and to my surprise I got an error claiming “Wrong Password.” So, I went to the Samsung website and was able to login to my account there with the same password. I still reset my password and tried again with the same result. Afterwards, I tried a few different passwords and finally found one where I started getting another error “Processing failed.”
After some searching I found out that the tab connects to a service that has a separate account than the online account, and further searching revealed that I have to manually add the Samsung account before this will start working.
So, here is what you have to do.
Settings > Accounts & Sync > Add Account > Samsung account
Once you add the Samsung account through the above menu then go back and try updating. It should work now. Enjoy!
