JTAG Jasper 2009-08-08 D7371 CB1888

[vabatta]

Hi all,
it's lot of time that I don't make a JTAG hack, and my question is if my Jasper Console with dash 7371 and CB1888 is exploitable.
Personally, refering to http://team-xecuter.com/forums/showthread.php?t=53528 seems to be not exploitable...
Do you tip me anyway to try reading nand and check CB?

Thanks for support

Under System Settings I saw it.

You have to dump the nand to check cb its not on system settings

I know you have a JTAG candidate but reading my RGH roadmap for noobies would have also answered your question.

CB read from Nand-X: 6750

Not exploitable...

I have never seen a jasper on 7371 with that high of a Cb, could you post a screen shot of jrunner

Best choice is to update it like to 8xxx and use RGH, right?

I have, it's common for consoles with a 2009 MFR date or back from refurb. This is why we advise to check the CB, otherwise we could go purely on dash.

You don't have to update anything.

Protect your efuses, then do an RGH.
