Sorry for more troubles. But I tried installing mp-fremantle-community-pr. There were about 4 packages that the installer tried to install (using fapman). On the middle of installation, fapman crashed. Now apt-get upgrade shows nothing that it can upgrade. HAM lists Linux kernel for Community SSU (boot image for u-boot and multiboot) only in download section. I can see lots of hidden packages under upgrade section of fapman.

My phone still crash a lot. I checked the kernel version and it is still kernel-power v50. I don't want to do full flash. So please let me know what I should do to fix it.

Thanks for your work and help.
