If you are like me you bought a US version of the M532 and quickly realized Fujitsu doesn't offer an update to Jellybean for us. So what you must to is go here Technical Support pages from Fujitsu and download the UK version for this tablet. Then use a hex editor to modify the region code from 12 to 13 so it matches the US region code. Save it and transfer it to your SD card and follow the Fujitsu instructions on how to update your tablet. I did this with mine and it worked perfect, I would even say it runs better than it did with Ice Cream Sandwich. And as an added bonus you will get the extra business software that was loaded on the over seas tablets.
