When your TI-84 Plus CE dies, it may not be able to be charged. Here's some solutions on how to fix Validating OS boot looping which means your TI-84 Plus CE won't charge.

I wish we could disable “Validating OS”. When I pick up my calc, I just want to do the math. Not wait for a boot. Its why I still use my Ti-34 MultiView or Ti-86.
It didn't always used to be this way, on calculators below rev C there was no OS validation, it just booted whatever was on it. Once they introduced rev C (boot code 5.1.5) they added this "feature".
dude i wish i was in the us so id be able to attend opensauce, so many awesome creators i love are going and to now hear the guy thats saved my exams many times is attending aswell makes me incredibly envious of the people attending. Hope you have lots of fun and make some content there :)
Just bought it and it’s already doing this BS . Never had this issue back in my days 😭😭
My TI 84 Plus CE from 2015 is looking really nice right now
It’s like you can read my mind, my calculator has had this issue for ages now so I can’t even use it. After I gave up some months ago I’ve been waiting for something that could help me, thanks a lot for making thie
I still have a TI-84 Plus CE from 2015. (well, 2016, but it was used at the time.) Still works perfectly. My only guesses as to why they added that screen was to try and detect any "illegal" (assembly) software, or something that exploits loopholes in its security system. Nevertheless, they clearly implemented it very hastily, as it does not check the battery before verifying.
Fun(?) fact: the OS validation screen was actually added to the operating system before the hardware speed upgrade. That means that for a short time, you could buy an 84+CE with the slower hardware and the OS validation. Talk about a lose-lose.
Thank you!! My TI-84 Plus C Silver edition wasn’t charging. I pressed the reset button and now it is charging again 👏🏻👏🏻
sadly none of this worked so we had to send it back and get a new one
always a pleasure
Wish I could be at OpenSauce but it's too far away... will you be making any videos about your time?
Wish you could come! I expect there will be enough interesting stuff to make a video about!
I just had this issue. Omg I’m panicking. I tried troubleshooting. Probably need to buy a new battery
No need to panic. Contact TI Cares and they will send you a new battery for free.
You can ask to borrow a calculator from your teacher or library while you wait for a replacement. You can explain to them this is a very common issue with recent calculators. Communication with your teacher is very important if you want leniency.
If you need a TI-84 right now for homework then you can search for a TI-84 Plus app on the app store.
It seems like every time I see a TI-84 Plus CE, I feel there's something wrong or the calculator is yet again have a flaw.
Just bought one today and took it out of the pkg to charge and it’s doing this. 😒😒
🤓Thanks to you, my TI-84 Plus CE has come back to life. Thank you so much!
And this is why I'll never get a post rev A calc. Gotta love boot 5.0.0.0089.
Mine doesnt work Im going to a request a battery from the company
Damn, I JUST got it and id rather not buy a new battery, hopefully chsrging it over night helps
Dude i got your problem and trust me, it wont
same i got mine today because it got stolen the other day now its not opening💀
Thank you!
Thank you, the reset button worked ❤
he is back let's gooooo
The other fatal flaw is that ZERO calculators are just better.
If you want to use one you'll have to come to OpenSauce ;)
Do you plan on going to any other OpenSauce events?
I definitely want to see some events if I have time!
Hi, I was looking for a calculator for engineering, and I don't know whether to choose the HP Prime G2 or the TI N-spire CX II Cas, which one do you recommend? thank you
I still love the HP Prime G2 and many of my engineering friends like it too. Just be aware that the HP Prime hasn't really gotten any software updates in a few years so any issues you encounter probably won't get fixed.
@@TheLastMillennial New 2.2.15008 beta update with a lot of bugfix
I saw, I'll be trying it out when I have time
I'm in 8 th grade but I do 10th grade geometry and my class loves to brag about our calculators
Nice. You could 1 up them by making a cool program for your calculator tibasicdev.wikidot.com/starter-kit :)
@@TheLastMillennial yeah sadly my calculator is having this issue and I am waiting for ti to send out a free replacement battery
My brand new Ti-84 plus CE model L, got this error, I tried charging externaly but when I tried again, the calc doesn't turn on, the battery doesn't charge anymore.....do you think that can I revive my battery???....
The battery sounds defective and I wouldn't try charging it anymore. If it refuses a charge then it's preventing itself from further damage. Contact TI Cares and they will send you a new battery for free.
@@TheLastMillennial Ti Cares just Cares US/Canada users, I am from LATAM, they send me to a local distributor to BUY a new battery
@@TheLastMillennial I found a Samsung battery comparible: EB494353VU from a Samsung Galaxy Mini GT......but the problem that you can't charge in the calculator
I see. Did you but the calculator directly from TI or a reseller? Whoever sold it should honor your warranty since the calculator became 'defective' on its own.
I'm not sure if the battery you linked is compatible with the TI-84 Plus CE but if it fits and it has three contact pads then the calculator should be able to charge it.
@@TheLastMillennial yes it fits and contacts too, contacts fits the same dimen....battery level indicator works too with this battery....Maybe there is a chip in TI batteries that the calculator can detect to know if it is original or not.
just bought this stupid calculator :( and its alr doing this
if the battery is the problem why tf would i need to swap it with my friend lol
Older calculators never had this issue so I assumed it was an issue with newer calculators charging circuits. I will need to do more research to be sure though.
Can you try to make your own graphing calculator with a raspberry pie zero
Writing a calculator from scratch is a whole different ball game than the projects I do. I've tried emulating calculators on the Pi Zero but it's far too slow for emulation. You'd be better off using Wolfram Alpha or an existing calculator application for it
@@TheLastMillennial I see. But if someone else were to do it it would be pretty cool and it could probably be done significantly cheaper than a TI 84
There's a startup called Zero that's basically making a TI-84 but using an Arm chip. I've made a video on the latest prototype.
@@TheLastMillennial yes I saw one other thing. Why don’t they put a micro SDHC card slot on these calculators you could store a TON of program
Increased cost, complexity, and lack of demand from schools. If Zero becomes more prominent in schools then they may start exploring options like that.
Got mine 5 mins ago and this is happening
Same it won’t work
Why would they design a unit that needs to post its bios before it can enable charging?????? Whack engineering, that’s poor design. It’s bricked if the battery is left unused for some time.
