REVISED TUTORIAL IN ROOTING 2.3.6 SAMSUNG REPLENISH
warning for experienced adb users!: this was made with noobs in mind. you may learn something (from me! a noob! XD) but anyways, enjoy!
this does not affect anything on the phone except for adding the ability to access root permissions. CWM is not permanent, it disappears after you use it, and nothing on the phone is affected, as far as i know, but i had just factory reset the phone, so use at your own risk...
you may need to know:
root of a drive- drives are designated C:\ or D:\ or whatever letter in windows. Just go to "computer" and double click the first item. That location is the "root" of a drive.
Note: make sure you have at least 400 mb of memory (i know, thats alot, but just in case) on your sd card so you can back up your entire phone! i reccomend doing every optional step!!! It'll save you hassle if you have problems. If you can't make room for some reason, and you still wanna try, you should skip step 8. I don't suggest it though.
1. download "odin.zip" and "su" here: https://www.box.com/shared/620b03e95cc0814fefc8 and unzip to your desktop. if you dont have the android sdk, simply copy the "adb.exe" file from "odin.zip" to the root of your primary drive for later. Just go to "computer" and double click the top icon/item. It should say something about C:/. If you're on Mac, sorry. Idk much about it. As for Linux, I have no clue how you'd even try to do this. I love Linux but, sadly, can't experiment with this in it. WINE has its limits....... And I don't think adb or Odin would work.
2. download the "su" file and put into into "platform-tools" where you installed the android sdk, if you have it, or put onto the root of your primary drive if you havent.
3. start phone while holding "spacebar" and "p". "downloading..." should appear on the screen in yellow text
4. plug into the computer and run "Odin_Multi_Downloader_v4.42.exe"
5. select SPHM580.ops for "OPS" and Replenish-CWM5.tar for "One Package" (they should be the only options) DO NOT CHANGE ANYTHING ELSE!!!!!
6. hit "Start" and DO NOT REMOVE PHONE FROM USB.
7. as the phone reboots, hold "u" until CWM opens and set the phone down. you should close Odin now.
8. use the volume keys to navigate to the backup and restore option and use enter to select backup. wait for it to finish completely and take you back to the the CWM main UI. backing up here creates a pure recovery, untouched by anything. CWM is NOT installed into this recovery. continue with the guide.
9. open the command prompt (type cmd.exe in search or run in the start menu, depending on your version of windows) or use some form of terminal emulator on your operating system of choice. command prompt is preferred due to the fact i know it can get the job done, but do what you will.
10. navigate to the drive your sdk is on and into "platform-tools" or to the folder you put the adb.exe and su files on. the default should be [name of drive]:\Users\[username]\. use the "cd.." command til youre at the root of the drive, and if you installed the sdk, type "cd android-sdk-windows/platform-tools" or just go to the root of the drive and go to the next step if you havent. just be sure adb.exe and su are there.
11. type this in line for line, with enters in between. the blue "~#" in the later lines is the prompt you should have. do not type this. it will be in blue. (clockworkmod should still be open on your phone at this point)
~#mount -o remount,rw -t rfs /dev/block/stl12 /system
adb push su /system/bin/
~#chmod 777 /system/bin/su
DO NOT CLOSE THE COMMAND PROMPT YET FOR THE SAKE OF CONVENIENCE
If you have problems with that, try using CWM to mount "/system". Some friendly people over at androidcentral pointed that out. I personally didn't have that problem, but I'm glad it's fixed.
12. when your phone has rebooted, go back to the open command prompt, which should be where it was before you typed "adb shell"
13. type "adb shell". you will see a prompt of "$." type "su." if you have a prompt of "#" rejoice! you have permanent root! now you can go on the Play Store and find "Superuser" and "Busybox" (they should be free. if you cant find it, get ahold of me and ill try to supply the newest updates) if not, and you have a backup from optional step 2, you should go through til you hit CWM and restore the backup. if not, make one now and reattempt everything aside from downloads and the moving the files around on your computer. Also, someone said something about "chmod 06755 /system/bin/su", so if you might try using that instead of "chmod 777 /system/bin/su". 777 worked for me, but maybe this works better for you.
OPTIONAL FINISH STEP: I dont know how you install CWM permanently, but you should do this so you can make backups of your rom and store them somewhere like on a box.com or mediafire.com account if you decide to mess with something on your phone. (use hjsplit to break it into pieces for uploading and reassemble after download for flashing if its too big). to use a recovery, enter CWM (either the way i have here or if you have permanently installed, just reboot and hold "u") and navigate to "backup and restore," "restore," and select the recovery you wish to use on your sd card (make sure when you take out a backup for storage, you zip up the entire folder with the name that contains the date and time of your backup.) it will overwrite everything on your phone to be exactly like it was when you backed it up.
good luck! have fun!
Note: if you rename the CWM backup file, make sure it DOESN'T HAVE A SPACE or it'll give you something about md5 or something not matching. If it says this, remove any spaces in the name and try again. I had it happen on my xperia play and freaked, thinking it was soft-bricked permanently one time, til I found out about cwm's glitch with that.
Also, I uploaded pretty much everything needed for rooting the phone, with comments pertaining to each file. This includes current (as of July 31, 2012) copies of Superuser.apk, a busybox installer, and the busybox and su binaries, as well the Odin package containing the tools to temp flash CWM.
the odin.zip file and the process of achieving CWM temp-flashing was found at http://forums.androidcentral.com/sam...d-2-3-6-a.html and credit for that part is given to joshua.worth, although I took it a different path than he did.
Update to above info: to simplify things, I uploaded all relevant files to box so people can get them easier. The su file went missing from xda, most importantly, so I fixed that, and added an updated binary in case someone has trouble with the other one.

Sorry if it takes a while to respond. Life's been kinda crazy for me lately, and I am using my new phone (no service) to do this over wifi.
