This is a hybrid for the Curve 8900 device. I recommend uninstalling any other OS’s off of your computer and running CCleaner (including registry cleaner) to ensure a clean install. Please back up all your data before proceeding.
-This is meant to install over the leaked 22.214.171.1244 base OS.
-Run Willyboy 8900 v2.1.exe to install the hybrid over the base.
-"Exit" the installer, Shrink-A-OS will pop up. Shrink out all languages you do not need to save space. DO NOT shrink out default themes or fonts.
-If you choose to wipe, now would be the time to do it.
-Launch loader from SAOS. If core applications are missing from loader selection, try launching from BBSAK or BBMCP.
This is a .554 radio and .566/.571/.591 build.
-East Asian Language Support resources are included
-New leaked BBM 126.96.36.199 included
-New App World included
-FAST boot times

I apologize for the media player issues. If you have not installed the OS yet, I updated the link in the OP so the hybrid download has the updated files. If you already installed the hybrid on your phone, please download this patch and install via BBSAK to fix the issues. v2.1 Media fix
Other than that error I hope everything is running perfect for you all! Sorry for any inconvenience!
