You mean a original, unmodified Firmware Update? Don't worry, this is not really compilcate and very easy to handle.
Visit the Sony Homepage in your language or UK, go under Support or Help and choose the device typ and then your model. (in our case
eBook Reader >> Sony PRS-T1)
Now you've access to all necessary things for your Sony PRS-T1. (like driver, manuals, technical details) Under the Tab
Download you found the Reader-Software and Firmware-Updates.
There you can choose one of them, I've linked the current updates here:
For PC |
http://www.sony.de/support/de/produc...PC_v1004_12210
For MAC |
http://www.sony.de/support/de/produc...AC_v1004_12210
Don't worry, the only important thing is to have full charged battery before you update. But this hint and more details you will find in the Firmware-Update pages too. (like alternative update methode without PC/MAC, over the "HELP>Check Updates"-Menu)
