Sorry man... apologies... you have all reason, the people dont follow step by step the cheff recipe.
I tested Cyanogenmod and AdyScorpius MIUI ROM, and the best was Ady*
i think that AdyScorpius Rom is better. v2.3.31 was fixed many bugs, the camera works and usb mass storage too.
i install the rom 3 days ago and all its ok...
MarkHUK can you send me your camera.apk and mms.apk? The problem was overwrite this apks in my SGSII Miui 3.2.3 with the official ICS for Galaxy SII. Now the message is: Application Cannot Install.
If you can send this apks my email is: egerman@coppel.com
Thanks
