Title: Calculator archive corruption - won't let me send from calc to pc or group stuff
Post by: Drak on June 19, 2009, 01:00:34 am
my calc is a piece of shit. every time I group stuff and ungroup it keeps giving me "error memory" and when I link to TI connect half the time it doesnt even detect the calculator, and when it does, it says all the files are invalid. what gives?

Solution:

2ND
MEM
7
LEFT
1
2

If that doesn't work, re-install your operating system.  To do this, pull a single battery, then hold [DEL] while putting it back in.  When prompted, send the newest OS from your computer

If that doesn't work... Buy a new calculator.

I had this happen to me once, clearing your RAM might fix it, what flash apps do you have on it?

Nah, after MSN chat, RAM clear didn't fix it. I'm unsure about ON+CLEAR forced reset, though (then regular RAM clear). I think the only way to fix it is to reset the entire memory or resend the OS.

No matter what, I think you should write down a couple of important project notes so if you get a full memory reset then you lose less stuff. Some stuff can be easily redone, but other stuff can be harder if you don't remember how it was.

I do hope a full mem reset will fix the thing, though.

I think it's a bug in the TI-OS that writes invalid groups at some point. I don't know what causes this, but I've run into problems with it at times. Makes me want to write a group file recovery tool for this type of problem :P

Other than that, maybe you have a piece of Flash that's wearing out. There's a strip of code in the bootstrap that performs this test on Flash, but it wipes everything out on the calc, including the OS. You can jump to this address, as it usually starts with "LD HL,<somenumber>" where that number is a pointer to the text "Testing Flash"

I'd definitely want to try the ON+CLEAR thing first, as that seems to have helped a lot of people out on those that asked about it on UnitedTI. Something to the effect of preventing the VAT from being reconstructed or something so you can go straight to clearing out whatever from your memory.

After that, get an OS that works. I would grab one from another person since the newest one is like total crap.
