Well Done!
Works perfectly thank you so much
@Code4U ! Followed the directions to the letter, everything went smoothly.
Update: I tried this on my Pantech Burst so I could give my gf's DB account the 50 GB too. It worked perfectly again. This phone is running CM 11 and I flashed the zip from ClockWorkMod Recovery v 6.0.5.0. So IMHO, it shouldn't matter if you're not on stock, just make absolutely sure you clear all of the dropbox app's data off your phone before you try this. (Run a root enabled file explorer, search your entire device for "dropbox" and delete anything you find).
It does't work for me, says "E:signature verification failed" while trying to flash the zip file, any ideas? I'm trying on a stock Galaxy SII i9100
Have you tried disabling signature verification in the settings for whatever recovery you are running? I'm on SafeStrap which is based off TWRP, there's a checkbox toggle to enable/disable signature verification on the install screen, I made sure that was not selected before I flashed this.
If you're using CWM there's a an option "toggle signature verification", selecting this will let you know if signature verification is enabled or disabled. Ensure that it is disabled, and try flashing again.
