Good job on reviving not one but two old threads and without enough information for any helper to work with. You have yet to provide: - Any softwares you have downloaded and used. - Any overclocking, if so to what extent was the modification. - Any dual/multibooting (i.e. with nitdroid/meego) - Hardware revision of your device. - If the device was exposed to extreme environments (i.e. dropped into water, dropped onto floor several times, dirty/dusty environments whilst back cover is not on the device, constantly replacing/removing of SIM card).
