Here is what I have done:
After a crash I decided to reinstall my 84's OS since it wouldn't get past the ram cleared screen.
Now it will install the OS but fail the validation after 3 seconds and ask for it to be reinstalled again.
I've tried XXX times...
I have unsigned installed, and can't get past the "Waiting... Please install operating system now."

I have used the mode key on the install screen to erase all flash - many times.
I have tried reinstalling ti connect.
I have replaced all the batteries. (including the backup)
I have tried power + mode to reset flash.
And each time it does exactly the same thing: Successfully transfer the os, validate, then error and go back to waiting for an OS.
Any suggestions? (it has been a day now and no luck)

Edit: I fixed it.

Oh good. Just for future reference, how did you do it?
Hello,

I meet the same situation.

Could you tell me how you solve this problem?

Thank you.

Welcome to Cemetech!

Assuming you have tried all of the ideas listed in the first post, here are some ideas:

    [2nd]+[del] and reset button on back (again)
    (My best guess:) clearing all storage with [clear] multiple times
[2nd]+[del] and reset button on back (again)
(My best guess:) clearing all storage with [clear] multiple times

these action doesn't work
Did you try clearing storage at the OS installation screen? And then trying to load the OS?
