Fix COB FLASH



hi again

to day we have 4GB HP flash
this flash is not working

First step we must check Fuse

1-use multimeter
connect black wire on flash disk 5volt and red wire on GND show 630~650
if show betwen 500 and 650 5volt fuse is ok

if see the range your flash 5volt fuse is safe

if not try to found 5volt way


2-test DP DM

also use multimeter to see range betwen dp dm you must see in 1 second 1200~1500



ok we know test dp and dm

to day hp 4gb 5volt show «0» we found 5 volt way and use wire to connect 5 volt

in this picture i show the dp dm and 5 volt line

solder 5volt to line and flash is worked again

this flash have important data and we fix it
with out any flashextractor or pc 3000
