[Galaxy S I9000 Q&A, Help & Troubleshooting] xsenman:
What you said above and what is written below, is not the same as you mentioned you use Pit file when flashing a rooting kernel, maybe if you follow as written, you may not have a problem as too many members had done it and have NO problems.

Procedure:

1. Fire up Odin3 on your PC and ensure KIES is not running on your PC by killing (Kies.exe , KiesTrayAgent.exe, and KiesPDLR.exe) using Task Manager

2. Put the phone to the Download Mode by pressing (VolumeDown+Home+Power) buttons and connect the phone to your PC (your phone should be recognized)

3. Select PDA > CODE_I9000XXJVU_CL851880_REV03_user_low_ship.tar.m d5

4. Select PHONE > MODEM_I9000XXJVU_REV_00_CL1092175.tar.md5

5. Select CSC > GT-I9000-CSC-MULTI-OXAJVU.tar.md5

6. Select PIT > 512 PIT (If 'Re-Partition' is not checked under 'Option', check it)

7. Press the Start button Do not press anything else or interrupt it, wait for flashing process to complete and phone will reboot

After which you repeat steps one and two (to flash the kernel for root and CWM recovery)

3. now select PDA > CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS

4. press Start Button. Do not press anything else or interrupt it, wait for flashing process to complete and phone will reboot

That's it, now you have a perfect Phone, rooted and having CWM recovery, ideal starting point for upgrading to ICS and after that to Jelly Bean custom ROM's

Basic CWM Flashing Procedure​

No need to read if you know how to use CWM flashing procedure​

From here on you won't be using Odin3 to flash anymore, you will use the CWM Recovery by using the 3 combo keys to enter recovery or you can use apps from Google Play like Mobile Odin, Flash Gordon or Flashify to Flash direct from your SD cards, so First you need to download the ROM of your choosing into your SD card ( Internal or External) together with gapps for it.

1) After flashing recovery with Odin, You can enter " Recovery Mode" by press VolumeupKey+PowerKey+HomeKey. You do this every-time you want to switch to a JellyBean or iCS ROM or to utilize the many features this recovery has, like Backup/restore/fix permissions and mostly to do the full wipes (NEEDED to be done every time you want to SWITCH ROMS) etc

2) Once in CWM Recovery you do the Full wipes (use your volume keys to move up or down in the recovery menu to select and the power key to execute that command).

The undermentioned wipes need to be done and will constitute a FULL Wipe of your Phone but your SD card will not be fully formatted as such your Images and other non system files will remain as is.

a) Wipe data / Factory reset

b) Wipe cache

c) Enter advanced and wipe dalvic Cache

Once the full wipes are done,

3) You now choose the ROM you placed in your SD card by selecting "Install zip from sdcard"

​

which will lead you to "choose zip from sdcard", which will take you to all the folders you have on your SD Card..scroll down to where you placed the downloaded files and select it

Once selected the ROM will be Flashed on to your phone, so wait till it says "install completed"

Note:- Some ICS ROM's may need to be flashed twice as it will end-up in bootloop in the first flash

some need to be wiped again after flashing ICS, as certain apps may not work.*

so repeat the ROM flashing one more time

Also if you intent to upgrade to JellyBean after this, you don't have to flash Gapps here , so you can skip the next step and just "Reboot System" after this

Now you do the same selection process again (Step 3) to select the Gapps file and wait till it says "Install completed"

4) That's it, Now select "Reboot system Now"
