Card wont flash ntrboot when i press inject ntrboot bottom screen qrites writing blowfish key (1) and then screen goes blank without respondinh

[jason0597]

you can inject ntrboot into this flashcart, but there's a chance that once you inject ntrboot into it you may not be able to unflash it in the end

also, the support for these flashcarts is still in the development phase so it may not have 100% reliability (it may brick your flashcart in the flashing process for example)

one more thing; you shouldn't make a new issue about this, you should instead ask here
