301-13 Will NOT UPDATE/JTAG

[corrosive_acid]

I have a 301-13 that doesnt update, it hasnt been hit and the location Id is fine, I'm assuming it was vid modded by some dealer guy long long time ago, but I havent used it in a very logn time and now when i put it in the stream it gets stuck on Vital info dl'ing.
then its says Please wait: Status Acquring Satellite info
But past this nothing EVER happens and I havent been able to jtag it (but i might be using the wrong jtag)
How can i get this to take the update, so i can put a autorest lock on it and not have to worry bout ever jtagging it.
IT DOES WORK with blue cards/magic.

What sector did you erase? ........After erasing SA49, try a single location read at 7FF10002, see if it is FFFF, not FFFFFFFF, cause that's a bad read........keep trying, by exiting the flash programming section, until you get a good read of 4 digits, it MUST read FFFF in order to verify a good erase.

this information is very helpful, thanks
Now i just need to build a jtag for this thing cuz I don tthink my quad mode jtag will work with it.
