If you are on the .320 Leak from TBH and want to get to the .340 OTA follow the instructions here:
TBH Patches: 2.3.340-System, Baseband, 2.3.340-Kernel, Bootloader
If you are on the official .340 OTA no worries you are good.
Now, this is really important. Once you are on the official .340 OTA or used the above info to go from the .320 Leak to the .340 OTA you can use the "LEAKED version of Rubix Focused 1.9" then just use this patch after you install Rubix Focused 1.9:
PATCH — Focused 1.9.0 update to 2.3.340
Once you have done that you are good to go and can use ANY Theme for RubiX Focused 1.9!!! Woot!!
