Can you Still First-Time Jailbreak an ATV2 to < 4.3.1 without SHSH?

Apple TV 2G software version 4.1.1 is iOS 4.2.1
Software version 4.2.1 (2100) is IOS 4.3.1.

Thanks, that clears it up. Yeah no XBMC sound except static using HDMI here at 5.1 AC3/DD51. I don't know if anyone actually has it working.

I know this guy says he did it: http://forum.xbmc.org/showpost.php?p=772...stcount=98

But the process he posted, while useful as a guide for setup, doesn't add any extra magic or anything. My guess is that he just is using 4.1.1 and not aware, maybe.

and i hink he just has the "right" av receiver

You sure? In iOS build 8F202 I thought Apple upgraded the Apple TV software (4.2 to 4.2.1) but not iOS itself (seems like it stayed at iOS 4.3). If 8F202 was iOS 4.3.1 wouldn't the ipsw names have changed too? Anyway, here's the pages I used when I went digging.

@jd2157 you are correct, 4.2.1 (2100) is more like iOS 4.3 as it was released before iOS 4.3.1. However, for all intent and purposes for JB it is considered in the 4.3.1 family.

@BDPNA & @Memphiz if you read further in the post you will see that I also have the AC3/DTS issues, but at least now they are decoding. Keith, the guy who is lovingly working on the ATV2 build for us, states that he has no issues what-so-ever with AC3/DTS over HDMI and he lists his components. If you need it and can't get the latest build to work then I suggest you go back to 4.1.1 (iOS 4.2.1 equivelent). However, Keith has mentioned that he should have a newer build by this weekend, next week at the latest. If you can hold off for just a bit longer, maybe this tweak will correct your issue. Be warned, though, that he says that he is not specifically addressing any audio issues.

Considered in the 4.3.1 family by whom? Both iClarified.com and Wikipedia indicate that build 8F202 is built on iOS 4.3 and not iOS 4.3.1. Also, when you look at the naming of the ipsw file from Apple themselves it's 4.3 and not 4.3.1:

So yes I agree, by many people it's "considered it part of the iOS 4.3.1 family" but that doesn't mean they're correct. Version numbers between Apple TV software and iOS are confusing enough so IMHO it's best to stick to the actual versions in hopes of reducing the confusion.

I'd assume the next build out won't fix the ac3/dts issues. The issue most likely won't be fixed until AudioEngine is merged... But there is currently no ETA to when this will happen.

As for having AC3/DTS working with 4.3, I can't find a single post in the forums where someone has it working, apart from Keith. He is one of the lucky ones to have a compatible setup.

For me 4.2.1 with the latest official build of xbmc is the most stable.

Yeah I made the mistake of calling it 4.3.1 also. I think it's better known as 4.3v2

4.3_8F191m (4.2) being version 1
4.3_8F202 (4.2.1) being version 2

LOL still doesn't make much sense to me considering 4.2 (4.1) and 4.2.1 (4.1.1) were named differently *shrug*

Is the ac3/dts issue with 4.3 a xbmc issue or is it a jailbreak issue?

Seems to me that the issue has to do with the jailbreak, since the same xbmc build works fine with the older ios firmware.

@jd2157 from a Jailbreak standpoint, the iOS 4.3.1 exploit is the same used on the ATV2 4.2.1(2100). That is the only thing that I am getting at. So when you talk about jailbreaks, it's the 4.3.1 jailbreak, lumping in the ATV2 4.2.1(2100).

As to the right way to call it without causing confusion... good luck. I even got caught up with the version being off from the iOS build so I would rather go with official ATV2 versions, such as 4.2.1(2100).
