Semitethered Jailbreak 0.7.9 [iOS5 only] Cydia Apps

* 주의 *

좀 불안한듯합니다.

탈옥에 대한 책임은 본인에게 있습니다.



반탈을 하게 되면 가장 문제시 되는거라면 배터리 방전일겨우 일겁니다.
Bigboss 에 다음과 같이 Semitetherd 트윅이 올라왔습니다.
세미탈옥이라고 표현이 해야할까요 -_-aa
뭐... 이름은 그냥 세미탈옥이라고 표현하고

이것이 무엇이냐?
반탈을 하게 되면 배터리가 방전되거나 리부팅시 탈옥이 풀리면 탈옥이 풀리면서 벽돌이 되게 됩니다.
자세한 사항은
iOS 탈옥 개념 정리 Part.1 [탈옥] 를 참조하십시오.
그러다보니 배터리관리를 잘해야된다고도 하죠.
벽돌이 되면 충전을 다시 하더라도 부팅이 안되니 재탈옥을 해야하니
그동안 중요전화나 메세지를 확인이 불가능하다보니
레알 연락두절 상태가 됩니다.

그런데 이것을 대처하기 위해 세미탈옥 트윅이 올라왔습니다.
세미탈옥은 위와같이 반탈상황에 배터리 방전이나 리부팅시 벽돌이 되지 않고
순정상태로 부팅이 되어집니다.
그러다보니 급한용무의 전화나 SMS는 수신이 가능합니다.
그렇지만 다시 탈옥상태로 돌리기 위해서는 다시 탈옥툴을 이용해서 재탈옥을 해주셔야합니다.
그러니 완탈이라고 부르기엔 모자르고 반탈이라 부르기엔 또 아니고 하니 세미탈옥이라는거겠지요

단점이 있습니다.
아직 완벽한 버전이 아닌듯합니다
전화나 SMS 등은 다 가능합니다
하지만 메일이나 사파리는 작동안합니다.
그러나 사파리나 메일은 앱스토어에서 다른 어플로 대체해서 사용하시면 됩니다.

설치법은 매우 간단합니다.
반탈을 하신 후 시디아에서 semitether 를 검색하시면
다음과 같이 트윅이 하나 나올겁니다
참고로 전 큰형님 서버에 검색이 안되어서
repo.insanelyi.com 소스 에서 설치하였습니다.

추가합니다.
빅보스의 별도 소스를 추가해주셔야합니다
.
http://thebigboss.org/semitether 를 추가하시면 됩니다.

지원기기는 다음과 같습니다.
아이폰4, 아이폰3Gs, 아이패드1, 아이팟터치 3세대/4세대

아이패드2와 아이폰4S는 지원안됩니다.


설치하시고 리스프링만 한번해시면됩니다.
두번째 사진은 리부팅을 시켜보았습니다.
시디아 / 드림보드등 설치한 어플은 다 깔려있지만 실행이 안됩니다
외부에서 배터리 방전되어도 걱정이 없을듯합니다.
충전하고 임시적으로 순정상태로 사용하다 집이나 PC를 사용할 수있는곳에서
다시 재탈옥을 하면 다시 탈옥상태로 쓸수 있겠죠 ^^

Semitethered Jailbreak

Author: BigBoss  //  Category: Apps, Jailbreak

Edit: October 23, 2:37am. 
I updated to 0.7.9. This version will take about 90 seconds after it first boots up and then your device will respring again. This timing was the only way to get some of the launch daemons to properly relaunch.

This version should fix issues for some of you folks where:
1) Device does not sync with itunes and only errors. Hopefully solved.
2) Device reboots after 2-3 minutes.
3) App sync issue – this is unworkable. Appsync hard patches system files and does not even use mobile substrate. I had to conflict with it. For now, semi-tether boot is impossible with appsync. You guys need to bug those guys to fix appsync to use mobile substrate (like everyone else uses).

Note, Saurik is working on an update to mobile substrate that will solve many of the issues with the semi-tether package. Hopefully this will be out in a day or two. At this time, we can finalize beta testing. I plan to hold further updates until after Saurik has released his mobile substrate update. Saurik’s updates will eliminate the need for the long 90 second respring on boot also.

This update was only tested on iphone 4. After saurik’s mobile substrate changes, more devices will be tested. Next updates coming in next 2-3 days.

Original Post:
My iOS5 semitethered jailbreak package is ready for beta testing. What is semitethered jailbreak and why do you care? In short, it is protection for if your device reboots while you’re on the road. Read on.

As you may know, iOS5 currently has a tethered jailbreak. This means that after you have jailbroken and installed most stuff you care about, you go to reboot your device, and it will no longer boot. You will be either stuck at apple logo forever, or you will get to itunes restore screen. When this happens, you have to hook up to your computer and use redsn0w “just boot” feature which gets you rebooted successfully again. It’s not all bad, as iOS5 is pretty stable. But if your device crashes and reboots while you’re out on the road, you are screwed and without a phone until you get home.

An untethered jailbreak is one that does not have such problems. Here you can reboot and the device reboots successfully. Because we are using the limera1n exploit discovered from Geohot last year, we are always guaranteed a tethered jailbreak on last generation devices. A new exploit will need to be found to untether us.

To get us through this period, I have worked on a semi-tethered solution. The semi-tethered jailbreak will allow you to reboot on the road, but with limited functionality. It is enough that you are no longer stranded, and you can use your phone, text, and many other features. This is just until you get home and can use redsn0w again to “just boot tethered”. Once you do that, you’re back to fully functional state.

Here is a summary of what you can and cannot do when in semi-tethered reboot state. Remember, this is only when your device crashed and rebooted on the road and before you got back to your computer to “just boot”. It is better than being stuck in apple logo:

1) Can use phone, sms (text messages)
2) Can use every other stock app on iphone.
3) Cannot use mobile safari
4) Can use other appstore web browsers such as atomic web browser
5) Cannot use mail app. You could install a gmail app from appstore or such instead.
6) You cannot use any jailbreak tweak, app, cydia until you boot tethered.
7) While in the semitether booted state, you should not add a jailbreak ios5 notification such as sbsettings to notifications during this state or your device will be stuck in a respring loop until you get home to “boot tethered”.

Those are all the limitations I have found so far. There may be some others. I may provide a more technical write up on why these limitations exist, but for now it doesn’t really matter. They just do.

Now, there are some other caveats to installing this package:

1) The device will take longer to boot up. When you reboot, it has to reload every service. It will respring a couple times also.
2) According to Saurik, there are some “problems” to reloading all daemons on the fly. This is why mobile substrate installation requires “reboot device” in cydia. I have not experienced any of these problems, but I am not promising they do not exist. This is why we will need testing to see which problems may occur.

I believe the good outweigh the bad here. Once the untethered jailbreak is out, you will not need or want to install this semitether package. In future iOS versions when we are back to having only a tethered jailbreak, you should be able to install this again to semitether your jailbreak.

As far as support for this package, please send me email preferably from Cydia so the proper semitether subject is used. If you want to email me from a computer, and want a response, use this subject: “Cydia/APT(A): semitether”. Remember, this is still in beta stages and may not be perfect. Do not install this if you are not prepared for that.

As for current testing, I have only tested this on an iphone 4 GSM running iOS5. As further testing shows success, I will update this page. Further, when this package seems stable enough, I may move it into the main bigboss source.

To install this, add the following repository to cydia: http://thebigboss.org/semitether. Note: after install, you will have to reboot your device, so make sure you are prepared at a computer to reboot tethered with redsn0w or just “home button out” of cydia and manually respring until you get home.

To test the success of this, simply reboot your device. If it boots up, it worked. Make sure you are near your computer so you can tether boot it after to get your jailbreak functionality back.
