Just wanted to say, brand new Kindle voyage owner here (previous Iliad, then Sony PRS-T1, the buggy version that kept freezing, hence finally switching to the Voyage), took it out of the box at 11am, plugged it so that it would get a full charge, and it's now 4pm, it's jailbroken, KUAL is installed, Koreader too, as well as a bunch of other stuff (screensaver, which took forever, but is finally on).
Thanks a lot for the very clear instructions.
There was a huge moment of doubt when after I uploaded the factory firmware, the Kindle restarted, did the update, restarted again and then got stuck on the start screen (the boy reading sitting below the tree), like forever, with no progress bar. I read that it could take a while, but because the update was already done and the kindle had restarted, I must say I panicked a little bit for a minute. But finally, things started to move again, turns out the update was still going on.
Anyway, just wanted to say thanks, now I'm uploading my entire ebook library, too bad Calibre didn't want to upload a single epub on the Kindle and is forcing a conversion on me, I guess I'll have to find another way to test Koreader
Main drawback for buying a kindle for me was the "closed" system, so I came back on the forum a few days ago, and when I found out it could be jailbroken, I finally made up my mind. I bought mine second hand, because I saw somebody bought his in Germany recently and was unlucky enough to get a model he couldn't jailbreak. At least with an older one (6 months), I was sure it would work.
