Hello everybody, I am new here speaking, but I've been working with all the information you (Ti-Planet, Omnimaga, ndlessly, basically the Nspire community) gave me since 2012. I have my Nspire CX since early 2012, it's a revision C. I've been following all the updates on the calc you guys gave me since ndless 3.1, but I abandoned it when OS 4.0 came out. Now all of a sudden tools to partition the nspire appear and boot1 exploits appear, I am impressed
This is my story, I flashed nboot, controlx in my diags partition, and boot2 4.0.3 in my extended partition (I still have boot2 3.1 in my main boot2 partition, and it didn't ruined everything). Everything worked fine, but last night I got a bit drunk and used an old version of nsNandMgr and flashed diags partition (don't ask why, I also don't know). Conclusion, it wiped controlx, and my extended partition (by the way, I keep controlx alone in diags partition, and in extended partition I keep both boot2 4.0.3 and my diags dump). After I pressed reset, I was greeted with the old nspire B/W bootscreen, and it would load to half of it and then reboot. Tried to boot to maintenance mode (

) Didn't work... Diags (

) didn't work either. So I had a brick... But wait
How I fixed it:
The only way to fix it would be trying to understand what was happening. I had my nspire TTL interface "Harness", which is basically 3 old male to male breadboard wires, with one end stripped, on a very small pencil that is the exact size of the dock connector. But I had borrowed my FTDI adapter to a friend that is working with Arduino pro mini. But I had my arduino Mega around, which did the same work.
So from hyperterminal, I concluded it was loading boot2 3.1 completely but after that it would reboot. So boot2 was "fine". I took a chance and flashed a diags image to diags partition by pressing the key combo, I knew it would wipe that partition, but worse than it was it couldn't be... I flashed my diags dump image (I keep everything in my laptop just because...) And it would boot in a white screen and reboot immediately, so nothing done either... and I took my battery out for 10 secs, so that I could at least see the screen
Then, while thinking in another way to repair it, my friend says "send it to the factory", I said "I don't even have the stock manuf.img in it, they won't repair" and then the switch flicked... nBoot was still installed!
I opened hyperterminal, inserted diags flash keycombo (
+
+
), it said it wipped my diags image, and flashed ControlX.img in diags partition (taking the risk). And since I knew after flashing a new diags, it would change bootD boot mode to diags first, I wasn't worried. I pressed
and after it rebooted, it worked! It was in ControlX. I just pressed Z to uninstall nBoot, installed OS 3.1 and ndless, and flashed everything back to normal, even my stock manuf.img
Conclusion: always keep a backup of every nspire partition, and I am not sure that after last night trauma, I will reinstall controlX and nboot that soon
Don't drink and nspire, kids
Sorry for long text, but nothing would be possible if I didn't learn with all of you guys. I never created an account, but I needed to share my story with you guys.
