Ok, be gentle please. I am a total rookie and would like to update to JB with the link Sam gave us. I am bone stock. I saved the file to my SD card. Now to reboot in recovery mode I press the power and volume up and down buttons at the same time? When I do this, will I lose any saved or stored info like contacts or text messages? Thanks for the help!
o) Power off
o) Hold Volume + and - at the same time
o) - down to recovery, + to select it
o) When the droid icon comes up, press + and - at the same time to bring up the menu
o) Select the option to install from external device and press power to select it
o) Select the update, press power to select it
o) Sit back drink a beer, wait.
o) Once back at the menu, select the option to wipe cache (WARNING: Do not select factory wipe or data wipe....you will lose everything if you do....JUST the cache wipe) and press power to select it
o) Select reboot phone, power to select it
o) Get another beer, wait.
You will not lose anything doing it this way.
