My 2700a always worked fine for 2 years. Then after I upgraded to B75 and loaded 235 things started going bad. 235 loaded OK and worked for a week until 233 was needed again. Then I could not get 233 to go in. So I thought maybe I had a bad file so I got another copy of 233 from another site and that loaded OK. But now when I try to load 240 it loads all the way until 99% then it just hangs, and after a while it says "Flash Update Failed" and it leaves 233 in there. I tried to load the factory bin and it won't take that either, same result. I tried to load 233 again just as a test and same result. Has the boot code been corrupted somehow? Should I reload the B75 boot file? At this point it won't take any bin. It communicates fine like everything is OK until it gets to 99%, then... nothing. How can I get a new bin in there?
I posted this last week, it is archived now so I could not reply. I was advised to reload the B75 boot code. I did that but the problem remains the same. I realize there is no bin right now but I believe if there is ever a bin I cannot load it due to this problem. What happened? Can Jtag fix this or what can fix this? I believe I can never load any more bins in now even factory bin will not go in.
