Thank Geekmaster for your reply.
I can see and access the Kindle Drive for 20-30 seconds. So I guess it's enough for put that file you mentioned. I'd like to give that shot but I don't know How I can get that file.
Anyway, so this problem is just some boot file damage?. Is there any thread about this "Repair Needed" problem in Kindle Touch?. I tried search this forum but found nothing for KindleTouch.
