The file is corrupt or not downloaded complete.  File size is only 2131.

what do you think i should do? try to boot up the router from a USB ? tried
that yesterday but router couldnot read my USB Key

[awetzstein]

Did you format it for FAT 32? I'm pretty sure that's what it needs to be.

edit: this might help also

Ok i will try this because i formatted the file as a FAT and not FAT32

Find another USB thumb drive:  32 Gb, FAT32 FAT16

Make sure the firmware is not corrupt by checking/comparing the MD5 hash of the file.

ok thanks let me try this and feedback

[Leo Laohoo]

I made a mistake.  

Should be FAT16. 

[dacobelltacham]

hello if i have a 4G or 16G flash should it be FAT16 or FAT32 ?

[Leo Laohoo]

FAT16

[dacobelltacham]

ok i will try the FAT32 and FAT16 respectively
