[ROOT GUIDE] Boost Mobile Samsung Galaxy S2

Superuser zip is corrupted, had to go to their webpage and download it from there to get it to install on my phone.

i am also on FL24 and flashed this through Odin 3.04 with no problems. =)

That's good to hear..
But you had a bad download. The link to the su zip isn't bad many people have used it

Maybe I am wrong, but I did download it 3 times. That's strange. Anyway, I have developed issues as of last night. Randomly my volume turns down like when listening to Pandora now and maybe 2 times the screen blacked out other than the notification bar and then it rebooted. Anyone else experience this?

I did try downloading it 3 times, each with the same result. But it's ok, maybe I just got linked to it bad. As of yesterday afternoon I started having issues. While listening to music i.e. Pandora phone will randomly lower volume all the way down, and maybe 2 times while something was loading another page i.e. Craigslist my screen went black other than notification bar, then phone rebooted. Anyone else experiwnce this?

Sorry about the repost, wifi wasnt on and no signal so I didnt see it post till this one was finished.

That should be it! A couple of final pointers:
  • I would also advise investing in the program "Titanium Backup" in the market. This will allow you to backup and restore apps selectively, and best practice is to make a full titanium backup of all your apps and settings in addition to the nandroid backups. Never hurts to be safe.
  • Finally, if for whatever reason you need to go back to stock, or you don't want to be rooted anymore, there is a way to do it! Just grab the stock rom here (courtesy of Mark112887), unzip it and extract the tar.md5 file. Open up odin and flash the tar.md5 just like you flashed the AGAT kernel. It will take longer, but when you reboot your phone should be just like it was when you got it from Boost.

How long exactly does rooting back to stock take?? It has taken an hour or so now and I don't see a downloading bar on my phone.

Whether you are new to root, or an old hat at it, following these simple steps will get you root access on your device. That means you're going to have access to the file system, system settings, be able to flash custom ROMs, get wifi tethering working, and all that good stuff.

I can confirm that this process worked for me and others on the Samsung Galaxy S II Epic 4G Touch running build FH29 of the Samsung software (you can see what build you are on by going to settings and about phone). I nor anyone else where will accept responsibility if your device ends up bricked. That shouldn't happen, but in the event that the stars align and the gods deign your device to be sacrificed, you're going to be SOL (because if you brick by rooting you are technically going to violate your warranty and may not be able to return it). Also, I accept no credit, I'm not worthy, I didn't make odin, kies, the kernel or the su zip -- that was all done by people a lot smarter than I.

Before we get started, you are going to need a few things:

  • Download and install Samsung Kies to your PC
  • Download Odin to your PC and extract it into a directory such as C:\Odin
  • Download AGAT's Kernel for the SGSII
  • Download the Superuser flashable zip file

Got all that? Good. Plug your phone into your PC and make sure that the drivers are all installed and that your PC can recognize your phone.

Unplug your phone and pull the battery. Put the battery back in and hold Vol - and Power at the same time and release when you see the SGS2 logo. Then you should get a screen warning you about the evils of custom operating systems -- hit Vol + to continue and plug your device into your computer (note for all the newbs: this is what is referred to as booting into download or odin mode).

Open Odin back up and it should recognize your phone (you should get like a yellow window on the left side). Hit the PDA box and select the AGAT kernel you downloaded. Make sure that it is in the PDA box (that's important) and not another one. Also the only other boxes that should be checked are auto reboot and reset time. Check to make sure all of the foregoing matches up, then check it a second time. Screwing something up with odin and and will mess up your shiny new phone. Hit start and it should go through the process of flashing the kernel to your device.

When that's done, disconnect your device, pull the battery again. This time, boot by pressing Vol + and power -- this will get you into the custom recovery that was flashed along with the kernel (and once more for the newbs, this is booting into recovery mode). Choose mount usb storage and move the superuser binary over to the sd card. Then go to the main menu of the recovery, select install zip, then install from sd card (external) and select the super user binary zip file and flash it. This will install superuser on your device. Then reboot like normal.

You should see a yellow triangle on your boot screen -- this is normal. This basically tips off Samsung or whoever that you have flashed something over Odin via a PC. I can confirm that triangle away in the play store removed it from my device, but your mileage may vary.

When your device boots, you should now have root access. Make sure that the Superuser program is installed, and you should be all set. You're ready to flash other kernels, custom ROMs, etc. At this point I would STRONGLY ADVISE you to reboot into recovery (vol + and power) and make what is called a nandroid (a backup of your device) -- just go into backup and restore in recovery and hit backup. Then when that is done, copy the nandroid to your PC so that you have everything backed up in case you need it. You should always do this before flashing anything, that way you have a way to possibly revert back if something goes bad.

That should be it! A couple of final pointers:
  • I would also advise investing in the program "Titanium Backup" in the market. This will allow you to backup and restore apps selectively, and best practice is to make a full titanium backup of all your apps and settings in addition to the nandroid backups. Never hurts to be safe.
  • Finally, if for whatever reason you need to go back to stock, or you don't want to be rooted anymore, there is a way to do it! Just grab the stock rom here (courtesy of Mark112887), unzip it and extract the tar.md5 file. Open up odin and flash the tar.md5 just like you flashed the AGAT kernel. It will take longer, but when you reboot your phone should be just like it was when you got it from Boost.

Edit: I can confirm that this process also works for FI22 and FL24. It should also work for any TW build, though you may want to grab the corresponding kernel here (i.e., if you're running a JB stock rom, make sure you get a JB kernel). I would also mention that, if you have 4g service, most custom kernels will bork your 4g speeds. You're only going to get 4g speeds with stock kernels or AGATs repacks (which are on the linked page). The repacks are just stock kernels with custom recovery that will leave your 4g speeds alone. So if you want fast 4g speeds, get a repacked kernel. If you don't have 4g or don't care about speed on it, you can get any compatible kernel you want.

But, as noted above, if something screws up or isn't working right, just flash back to stock and try again.

is it the same for the sprint galaxy s II
 
First off i want to thank all the people who make this possable. Ok i just joined and have the boost mobile samsung galaxy s2 FL24 ics, i have'nt had it long and a newbe to rooting. Im having a little trouble understanding it all but wanting to root my phone and also have the stock to flash back if need be to get it replaced or fixed. my problim is that in Guyphs post above it shows the link to download the AGAT's kernel when i click on it im not sure witch one i need to download and when i click the link for the file to odin back to stock the page is blank. could someone please help.
 
help this is not working i rooted my warp no problems i followed everything when i open odin and put the kernel that i downloaded in there and hit start it says all threads complete
failed reset downloaded it 5 times same results
 
You should recheck what you're doing. Doesn't sound right

Try a different port on the computer. I've seen alot of people fail Odin. Change ports and pass
 
i think i messed my phone up bad it is just sitting on the samsung screen i rooted my phone first then i tried to install cwm but it was for epic 4g it lets me go to recovery and install or back up and restore then when i go to restart it just sits on the samsung screen help i just bought it fri
 
OK there are only a few reasons it would be doing that. Don't worry Its not bricked. I'm going to pm u my number. If u have a seperate phone to call me from i can walk u through it


Did u root your phone with Odin and the agat recovery.... Or did u use one of those root apks/ exploits?

Was the kernel you flashed with cwm for the epic 4g touch? Which one was it?

We can fix your issue right now with Odin if nothing else so don't worry

yes it was a touch
 
So what exactly did you do then? U still have stock recovery correct? Which means you cant flash any zips.


Or did you use mobile Odin to try to put the cwm recovery kernel on?

I need you to tell me exactly what you did before your wouldn't boot. Then i will give u a solution

What u did was flash a gingerbread kernel on a ICS ROM which is why it will not let u boot the phone!!! If u had a zip for a ICS kernel u could solve the issue by flashing it right now and it would boot up.
