J'avait anciennement planté ma TI nSpire lors d'une tentative de mise à niveau, et était persuadé de ne plus jamais pouvoir la recuperer. :'(
Mais je suis recement tombé sur ce tuto : http://tiplanet.org/modules/archives/downloads/repair301.pdf qui m'a redonné espoir.

Cependant, lors de l'étape III (envoit du boot2 avec cable TTL<-->USB ) survient un probleme : Le boot2 se transfert sans probleme mais l'erreur persiste toujours au redemarage ;
Voici ce qui s'affiche dans Hyperterminal :
