[Galaxy S II Q&A, Help & Troubleshooting] sea_salt:
Hello,

this F.A.Q should help, when you are confrontig the following situation: I want to root my sgs2, using the zergrush method. Probably because I don't want to change the kernels...

1.) Just to be sure, that I got it right: When I use the zergrush-exploit on my SGS2 (2.3.4) I get root access to the shell via ADB and nothing more. Then I push the app "superuser" on the phone using adb shell command. And then I can use the superuser-app to grant root only to the programs I want. All other programs are still not running in root. Is this right?

Answer from oinkylicious: If you use http://xdaforums.com/show...php?p=18805560 you won't need to manually push anything.

2.) Is there anyone else (according to the previous posts) who can confirm, that the zergrush-exploit does work on a unbranded sgs2 which has been updatet to 2.3.4 via KIES?

Answer from oinkylicious: It works fine on < 2.3.6

Answer from E:V:A: It is likely that all stock firmwares distributed & compiled after 9 Nov 2011 may be patched for the "zergRush" explot due to the bugreport filed here: https://code.google.com/p/android/is...etail?id=21681

However, there are always other solutions...

3.) When I apply the zergrush-exploit, …

a) … do I still have the possibility to use KIES to update the kernel e.g. to 2.3.5 (when it's released)?

Answer from oinkylicious: Probably

b) … can I still use KIES to backup my data (e.g. sms, calendar, ...)?

Answer from oinkylicious: Probably

c) … will there be the yellow warning sign while booting?

Answer from oinkylicious: No

d) ... will the legendary "counter" (sorry, I'm still a noob on android) count one up, and has to be resetted via an usb-jig before I potentially send it to claim my warranty in case of a malfunction, or will there be no "signs"?

Answer from oinkylicious: No

e) … can I still use "factory reset" by settings->privacy?

Answer from oinkylicious: Probably

4.) If I can still use...

a) … KIES to update the kernel e.g. to 2.3.5... will the phone then be un-rooted after updating via KIES?

Answer from oinkylicious: yes

b) … "factory reset" by settings->privacy ... or alternatively will the phone then be un-rooted after pressing "factory reset"?

Answer from oinkylicious: Probably, try it and find out.

5.) When I use the zergrush-un-root-function... will there be any traces that the phone was rooted before or will the phone be in the state it was when I bought it?

Answer from oinkylicious: There shouldn't be.

I know these are many questions. So I really really appreciate your help a lot! And I hope this will also help other people who got the same questions... As mentioned, I read a lot before in this forum, but for some questions, I couldn’t find a distinct answer...So I would appreciate it very much, if I could get some help, before I start to root my phone. I think it's better to ask these questions before I start to root, then afterwards...

If someone can confirm oinkylicious's answers or has other opinions, please don't hesitate to post them. I will include them in this post to get a more reliable FAQ... Also if there are more questions. Please ask them and I will add them here...

Best wishes,

mr. salt
