KaKaRoTo announces jailbreak for 3.73 - 改機

聊天室紀錄：

<KaKaRoTo> heri, docpaul showtime would work fine
heri、docpaul，像Showtime之類的程式應該是可以跑沒問題
<sandungas> kakaroTo, this means new tcl patches for mfw and some
changes to manage 3.73?
所以說會有給MFW 用來修改3.73版韌體的修補腳本囉？
<KaKaRoTo> ddoo, and no I didn't fix the npdrm algo, that's what
I'm missing (hence the "kind of") but I'm not working
on that, that's someone else's job
ddoo，還有就是NP-DRM的演算法我沒改，是我漏掉了（畢竟有點「
那個」），然後我也不打算弄，交給別人好了。
<middleman> gonna debut it at ccc kakaroto or before?

<KaKaRoTo> ddoo, and even if npdrm signing worked.. how do you install
your pkg on an OFW 3.73?
ddoo，就算能夠正常簽出NP-DRM認證，但在官方3.73韌體上要怎麼
安裝程式呢？
<heri> so KaKaRoTo, once the NPDRM algo is fixed, a release will come?
所以卡卡羅德大，那個NP-DRM改好後就能釋出了對吧？
<KaKaRoTo> heri, another missing bit, but once that's fixed, yes
heri，只差臨門一腳了，改完之後就OK
<KaKaRoTo> but I'll probably be off country for the next 2 weeks
但我接下來要出國兩週
<KaKaRoTo> so all work will have to be paused
所以手邊工作暫時只能先喊卡了
<heri> oh, fair enough. we can all wait 2 weeks hey :P we have waited
months anyways
喔，好吧。兩個禮拜的話，應該可以等，反正都等了好幾個月了。
<KaKaRoTo> ddoo, that might work.. you could also just install
your pkg on 3.55 then upgrade...
ddoo，這個辦法應該OK，先在3.55版韌體上把要裝的東西都裝一裝
然後再升上去……
<KaKaRoTo> ddoo, upgrading doesn't delete any of your packages
ddoo，升級不會把已經安裝的程式砍掉
<KaKaRoTo> ddoo, issue is, you're lost if you didn't do it before
upgrading
ddoo，所以問題在於，如果你沒先裝好的話，就沒救了
<ddoo> but they fail because the npdrm algo is spoted by the
checks in 3.56+
但就算裝好再升上去，不是也不給跑，因為3.56+ 韌體把那組金鑰列入
黑名單了
<KaKaRoTo> heri, also note, I "announced" it because I was excited to
see it work as expected
所以我說我是「宣佈」咩，因為結果跟自己想的一樣很令我振奮
<KaKaRoTo> doesn't mean it's ready for release
我可沒說已經準備要釋出了
<KaKaRoTo> ddoo, exactly
ddoo，沒錯，就是這樣
<heri> yeh thats what we were saying just before you came
你來之前我們已經討論過這個了
<KaKaRoTo> so you need : 1 – npdrm algo fixed, 2 – a way to install stuff
所以有兩個關鍵：1.修改NP-DRM演算法；2.找個安裝程式的辦法
<heri> you only announce when you are confident it works
所以你只是因為有信心能夠成功才宣佈的
<KaKaRoTo> 1 has been done by someone else (don't know if he'll share it),
and 2.. well, I just did it
1.已經有人弄了，只是我不知道他願不願意分享；至於2.我已經搞定了
<KaKaRoTo> heri, well, I was testing on 3.60 and it worked, but yes, I
did upgrade to 3.73 to test that it still works just to make
sure I don't tweet any false hopes
heri，嗯，我已經成功在3.60版韌體上測試過了，然後我又升級到3.73
，未求保險又在測一遍，還是成功，這樣才能夠確保不會給人錯誤期待
<middleman> but you can't run what you installed until 1 is fixed
correct?
但是你沒辦法跑安裝進去的自製程式，除非完成1.對吧？
<KaKaRoTo> middleman, exactly
middleman，沒錯
<middleman> interesting
有趣了
<docpaul> nice, thx KaKaRoTo
帥呆了

******

總結：
1.如果NP-DRM不是用real time memory patch而是用檔案抽換的方式修正，會
很麻煩，因為UM2.0 會查驗檔案完整性，所以一定要從3.55升上去，而且日
後升級到更新版會有困難，因此應該是利用漏洞進行real time memory
patch ，跟3.41時類似

2.感覺蠻麻煩的，所以我還是打算等金鑰跟metldr解密那邊
