all looks have worked far try following:

root@kali:~/router# lzma -d uboot.lzma  lzma: uboot.lzma: compressed data corrupt  root@kali:~/router# unsquashfs kernel.squash  parallel unsquashfs: using 4 processors lzma uncompress failed error code 0 read_block: failed read block @0x277af0 read_fragment_table: failed read fragment table index fatal error:failed read fragment table

any idea why may happening? prompt says, on kali linux. this

try

lzma -d < uboot.lzma > uboot

the error found due lzma utils having been superseded xv utils, don't ignore trailing garbage. if use stream (like gave you), you'll still have corruption error message in end, you'll file alright.

ios - Memory not freeing up after popping viewcontroller using ARC -

hi project arc based, using uinavigationcontroller make transition between viewcontroller. using profiler analyse happening behind scene memory. noticed when push viewcontroller allocate memory components , when pop not freeing allocated memory. since using arc unable implement dealloc or release component. have analysed in detail , there no memory leak in project. i not using strong property push viewcontroller. here how pushing viewcontroller. viewcontroller *obj = [[viewcontroller alloc] init]; [self.navigationcontroller pushviewcontroller:obj animated:no]; any clue whats going on? should free memory have consumed. please advise your description indicates have retain cycle, leads objects not being deallocated. typical source of retain cycles properties assigned loading nib files (usually declared iboutlet ). two strategies break them , release objects: declare property weak : @property (nonatomic, weak) iboutlet uilabel *statuslabel; set property nil in...
