Hardest part for me was getting a PC to recognize my Z10 when linked via USB. My HP Envy X2 running windows 8.1 only recognised the Z10 by wifi. In the end I had to resurrect an old XP powered Toshiba laptop I had in a cupboard that hadn't been used for years. After a bit of fettling - putting on XP service parks 2 and 3, .NET framework 4, Blackberry Link, Sachesi 1.1 for windows it was ready.
Open up Sachesi, put in the details 525 for country, 005 or just 5 for carrier and download the update. I connected my Z10 by USB cable, clicked the install tab, when prompted I picked the folder with the downloaded files that were in a folder with the Zachesi program. Zachesi then works its magic and you can follow the software being loaded as it lists the separate components of the OS as they're loading.
