everything works fine with my sgs2 with full wipe installation and flashing the latest version of siyah kernel... it ate a lot of my battery's life because I restored my data but I think that was just normal to drain because the new OS is calibrating the battery status of my phone and after...
Try to flash the latest siyah kernel after installing the ROM with full wipe. Here is the download link for the kernel: http://www.gokhanmoral.com/gm/2012/06/12/siyahkernel-sgs2-v3-3-2/ .
It works for me... :cool:
Finally, this ROM is now working great in my sgs2... Here is what i did:
- full wipe ( data/factory reset, cache partition, dalvik cache, format cache, system and data)
- install ROM
- install SiyahKernel SGS2 v3.3.2
