I've been compiling information for UnBrickable mod on the various versions of the Galaxy S2 device. This generation is by-far the most decentralized "model" I've ever heard of. Some of the devices contain Exynos processors, some Qualcomm and others have OMAP.

We've conducted research on this generation of device in the following threads:
AT&T GS2 UART/bootloader hacking: http://forum.xda-developers.com/showthread.php?t=1313588
Epic 4G Touch informiiation gathering: http://forum.xda-developers.com/showthread.php?t=1262081
Galaxy Nexus UnBrickable Mod development: http://forum.xda-developers.com/showthread.php?t=1310865

But you're here for the Galaxy S2 Hack Pack. This Hack Pack is designed to help out those looking for information on modifying and/or repairing their expensive devices. This package contains:

Reading Material
GT-i9100 official service manual - service manual which applies to most GS2 devices
Exynos 4120 public datasheet -datasheet explaining internal workings of the chip
Origenboard documentation -Exynos based development board
OMAP 4430 datasheets -datasheet explaining internal workings of the chip
FSA9280A datasheet -USB Switch chip which responds to resistors and routes communications around the phone
-(no information on qualcomm processors is available)-
model speciffic
AT&T SGS2 uart -UART output logs
i9100 IROM -memory dumps
i9100T bootrom -memory dumps
Epic 4G Touch pictures-pictures of internals
Galaxy Nexus specs -models of chips used in Galaxy Nexus
Android Binaries
bash - the best scriptable shell ever
i2cdetect -i2c address detector
i2cdump -i2c bus dumper
i2cget -i2c information grabber
i2cset -i2c information sender
tcpdump - monitors network traffic
viewmem - allows memory dumps
apps
smdk-tools - a set of linux development tools designed for direct communciation with the Exynos processor.

Download The Galaxy S2 Hack Pack

Please note, none of the contained information is my own original work. This has been compiled over the last month of researching this device. All information in this Hack Pack is available on the Internet from various sources.

Credits:
Samsung- i9100 service manuals and other tools.
SuperCurio- Model Numbers of the chips in the device were discovered by SuperCurio from a Voodoo Report sent from a Hong Kong conference.

Please let me know if there's anything I should add to this pack.

I am now using a Samsung Epic 4G Touch (Galaxy SII), but can't use Titanium Backup and other "root required" apps because my phone isn't rooted. Would this hack pack allow me to safely (as safe as I can at least) root my 4G Touch? If not, would anyone know of a link for the said rooting info??

It's been over a week and I am still not able to get answers on whether or not this will allow me to simply root my device. I'm not looking for any fancy Roms or anything like that. To just be able to use the apps I paid for and rename some ogg files to stop the stupid camera noises. Anyone out there able to help?? I'm beyond frustrated at this point. Help?? Please??

EDIT: The model of the phone is SPH-D710

Thank You CutBones. I made sure that my usb settings were correct, that the usb drivers said the loaded correctly and then I disabled my antivirus and downloaded the files. When I ran the files I got the appropriate menu. I sellected the 'A' option to root the device. The display confirmed that the USB was set right, the drivers were good and that the phone was connected and recognized. Then it said to press any key. When I did it said it was waiting for the phone to be connected. That's where it sat and did nothing. I tried 4 times. Any suggestions would be appreciated.
