Idiots guide to root/unlock a Galaxy S2

post #1 of 28
Thread Starter 
Hi all

I currently have a samsung GT i9100 or Galaxy S2. I need an idiots guide to getting this thing rooted/unlocked im not sure what the term is. Basically my battery life drains too quick, it doesnt last a day now even though I have internet off and screen display to minimum setting. I have seen people with a Nexus 7 who have it underclocked when idle, Id like to do this on my phone so that the cpu is running at like 10mhz whilst idle or whatever is lowest. I would also like to unlock the phone so I can use any SIM carrier if possible.

thanks

thanks ill have a look at that guide

Q; That guide is for rooting, does a rooted phone mean it can be unlocked?
post #4 of 28
Once rooted, you have Admin access to EVERYTHING, there are apps on the app market to unlock the phone, but most need root access as it envolves pathcing certain things etc, I recommedn rooting and did it ASAP when I got my device

Cool, I used that guide and installed Siyah v5.0.1 with Odin. Ive used root checker and it now says my device has root access. So I guess that means it has total root access?

Kinda

According to that guide I should make some backups of my phone, one of them is ttianium backup. When I open titanium i says "Sorry I could not aquire root priviledges".

But root checker says my device has root access?
post #8 of 28
When the app is opened, a pop up should appear saying 'allow root access etc'

Does this even come up? If not, go to the app martket and download 'SuperSU' and download, then try again.

I tied rooting again and now titanium is saying root access is OK.
post #10 of 28
