Currently have the stock 2.1. Went through the rooting process and have SP Recovery installed. I have "Superuser Permission"
Downloaded BB Updater and downloaded 1.1 ROM, file ESE81V11.zip
renamed the file update.zip and put it in the root of my SD card.
Ran sp recovery and the update went fine.
When the system reboots it never will boot up, I keeps redrawing DRIOD.
