Help, Bricked TI nspire cx

Hello,

I am in need of some help. I accidentally flashed about boot 1.5 while converting my Ti nspire cx to CAS. Now it is stuck on the loading screen half way. I have tried resetting it, to delete OS and all files but it does not work. Also, I tried getting to diag menu and it did not work. Please help, I do not want a bricked calculator.

to be more descriptive, I flashed over boot 1.5. I originally thought I had the older hardware version but I have a new one (last two letters AE) I flashed over, It said operating system not found. I then tried downloading the original software I had on the calculator, however this led to a frozen screen. Now it wont allow me to completely reformat or anything. Also, the undo + menu + minus then pushing reset has not done anything. I appreciate any help I can get. Critor if you are out there please help, you are the TI wizard of the world.

If the Boot2 doesn't work, and if

esc

menu

doesn't make the calculator boot, then I don't know of any software-only way to repair the calculator.

Try

esc

menu

again ? If you accurately followed the tutorial hosted here, it should work. That tutorial was designed to minimize the risk of bricking the calculator :

press and hold
```
esc
```
```
menu
```
```
-
```
(the
```
-
```
above
```
enter
```
, not the
```
(-)
```
to its left)
without releasing these 3 keys, press and release the reset button on the back
if the calculator didn't automatically turn back on, still without released the 3 keys, type
```
⌂on
```
, 2 times in a row if necessary
