[Q] Signature Verification Failed

[GreenRaccoon]

I can't figure this out for the life of me. I'm trying to flash the regular old stock firmware on my SM-P600 through Odin 3.09. I'm using "P600UEUCOB1", the Cellular South version (from sammobile.com).

Problem
It flashes great in the Download screen but once it reboots to finish the update, I get this error:

-- Installing package...
Finding update package...
Opening update package...
Verifying update package...
E: failed to verify whole-file signature
E: signature verification failed
Finding update package...
Opening update package...
Verifying update package...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted.

Afterwards, if I reboot the system anyway, it still works...mostly. I get a ton of force closes, and every fifteen minutes or so, the tablet crashes and restarts.

What I've Tried:

• Using the stock USB cable that came with the tablet
• Using a couple other USB cables
• Using multiple USB ports
• Reinstalling Samsung drivers
• Wiping data before flashing
• Unrooting and wiping data before flashing
• Flashing older firmwares (NK2 and ND2)
• Using Odin 3.07 instead of Odin 3.09

I get the same results each time: "signature verfication failed" and a half-usable tablet.

I'm out of ideas. Anyone have any suggestions?

Btw, if it helps, I'm comfortable with doing heavy stuff like Terminal commands or coding.

Hmm.. It seems to try and flash stock but fails. Like an update package. Is reactivation lock off first shown here. If that doesn't work, then the only thing I can think of is installing twrp and flash a zip based Rom. Like this http://forum.xda-developers.com/showthread.php?p=52058286 I hardly use Odin so yeah. Hope this helps!

Thanks for replying! I don't have anything like that on my Odin screen. I've attached what mine looks like.

Do you mean you use something besides Odin? If so, what do you use? I'd love to be able to do something under Linux. I've tried Heimdall but can't figure out how to fix the weird udev errors.

I've only used Odin to root my device. That's about it. If I ever need to restore, I just make a custom stock rom to flash in twrp since Odin seems to give me problems. Looks like some devices doesn't have reactivation lock. Have you tried factory resting after flashing in Odin and before also? The last thing I can think of is using Samsung kies to restore
