Hi.

i Upgrade my SCH-I800 to CM9. and it works good. and from last week not working. and its stuck it CM logo. so i tired to re installing it.

some how i was tried to boot my Tab back.

so tried below steps

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 1. Download the zip and unzip the contents to your Desktop (or where ever you would like). These are stock restore files (DJ11) for Download Mode (Volume down and power) Also download the wpa_supplicant and update.zip. Download all these files to the same directory so they are easy to find. I just use the Desktop.

Step 2. Download Heimdall from Here:

glassechidna.com.au/products/heimdall/

Also just below version 1.1.1 is Microsoft C++ This also needs installed on your machine because it has .dll files Heimdall uses.

Step 3. Power off your Tab. With your USB connected to your PC, hold volume down on your Tab, and plug USB into Tab. This will Launch Download Mode. Unzip heimdall and go into the drivers folder where you will see zadig.exe. Run this. At the top you see options. Click “list all devices”, then in the dropdown select Android USB composite device (or whatever it says). Click start and let heimdall download the drivers. Once its finished, close zadig and launch heimdall front end. (leaving Tab plugged in and in download mode obviously)

THIS IS THE IMPORTANT PART!!!!!! DO NOT SCREW THIS UP!!

Unzip the stock files if you haven’t already.

Now its common sense.

The zImage goes in both the Kernel AND Recovery slot. (they even tell you where things go with little descriptions)

The system.rfs goes in Factoryfs

The Param.lfs goes in Param.lfs

The cache goes in the cache slot.

DO NOT EVER EVER EVER PUT ANYTHING IN ANY OTHER LOCATION. THESE ARE THE ONLY FILES YOU NEED. **Note, if heimdall fails at the very beginning, just try unplugging and turning off the tab, close, and relaunch heimdall-frontend.exe. It will eventually start. Sometimes you just need the right combo of plugging in launching the program…

After you have the files in place click “Start” to flash. ALWAYS make sure your battery is sufficiently charged or you will have MAJOR problems. What this did was return you to STOCK EVERYTHING DJ11. This is necessary to flash the update.zip we downloaded earlier.

After this runs you will more then likely boot loop. Power down, wait a few seconds and hold power and up volume to boot into recovery. (NOTE, do NOT hold power too long, just long enough to turn it on, then continue holding up volume until you see recovery. WIPE DATA AND CACHE. Tab should boot.

Step 4. You should now be back to 100% stock DJ11, and guess what, you’re still rooted! The next step is to push the wpa_supplicant (For some reason this file makes the update.zip fail) to /system/bin using ADB. If you want, you can get root explorer on your Tab and put the wpa_supplicant on your SDcard. Then, use root explorer to copy this file to /system/bin (its ok to overwrite the one that is already in there). If you don’t want to bother with Root Explorer, do the following. Place wpa_supplicant into your tools folder with ADB.

Tab plugged into PC, with USB Debugging ON from your ADB folder (mine is C:tools) Type:

C:tools: adb push wpa_supplicant /sdcard

C:tools: adb shell

$ su (may need to check the Tab to “allow” permission)

# mount -t rfs -o remount,rw /dev/block/stl9 /system

#cd /system/bin

#cat /sdcard/wpa_supplicant > wpa_supplicant

#exit

$exit

Step 5. Place the update.zip file you downloaded on the root of your sdcard and unplug from PC. Power off your Tab. Boot into recovery. Hold volume up, press and hold power for about 3 seconds then release WHILE still holding up volume until you see stock Android recovery. Apply update.zip from sdcard.

This should start the update process, if it doesn’t reboot on its own, select reboot device from recovery. Once you’ve booted, you will be updated to the newest update from Samsung. Notice Superuser is still in your app drawer. (if it is not don’t panic)

*NOTE If you boot and it requests you to activate and won’t activate, do this to bypass activation. On the screen it asks you to activate use the volume toggle. Press volume up once, volume down twice, volume up three times, and volume down four times. It will then allow you to skip activation.

Step 6. Next we are going to download the Stock rooted images of EC02, and the VOODOO zImage.

We are now going to flash the rooted EC02 files via Heimdall. This will be the same process as Step 3, except we will use the new EC02 files.

Power off your Tab. With your USB connected to your PC, hold volume down on your Tab, and plug USB into Tab. This will Launch Download Mode. Unzip heimdall and go into the drivers folder where you will see zadig.exe. Run this. At the top you see options. Click “list all devices”, then in the dropdown select Android USB composite device (or whatever it says). Click start and let heimdall download the drivers. Once its finished, close zadig and launch heimdall front end. (leaving Tab plugged in and in download mode obviously)

THIS IS THE IMPORTANT PART!!!!!! DO NOT SCREW THIS UP!!

Unzip the EC02 files if you haven’t already.

Now its common sense.

The zImage (from the zip file, NOT the voodoo zImage you just downloaded) goes in both the Kernel AND Recovery slot. (they even tell you where things go with little descriptions)

The factoryfs.rfs goes in Factoryfs

The Param.lfs goes in Param.lfs

The cache goes in the cache slot.

DO NOT EVER EVER EVER PUT ANYTHING IN ANY OTHER LOCATION. THESE ARE THE ONLY FILES YOU NEED. **Note, if heimdall fails at the very beginning, just try unplugging and turning off the tab, close, and relaunch heimdall-frontend.exe. It will eventually start. Sometimes you just need the right combo of plugging in launching the program…

After you have the files in place click “Start” to flash. ALWAYS make sure your battery is sufficiently charged or you will have MAJOR problems. What this did was fix root for EC02.

After this runs you will more then likely boot loop. Power down, wait a few seconds and hold power and up volume to boot into recovery. (NOTE, do NOT hold power too long, just long enough to turn it on, then continue holding up volume until you see recovery. WIPE DATA AND CACHE. Tab should boot.

*NOTE If you boot and it requests you to activate and won’t activate, do this to bypass activation. On the screen it asks you to activate use the volume toggle. Press volume up once, volume down twice, volume up three times, and volume down four times. It will then allow you to skip activation.

Step 7. This is the final step. Instead of flashing recovery VIA Rom Manager (since the recovery in Rom Manager is not updated to the latest kernel source), we will be flashing @khasmek (aka Boushh from XDA) EC02 VOODOO kernel which will also give us a fully working ClockWorkMod recovery!

Again, we will be using heimdall to flash the zImage we downloaded in step 6 (NOT the stock zImage that was in the zip) Please make sure this file is zImage only on your PC. Flashing anything with an extension (zImage.txt, zImage.zImage, etc) will not take.

Power off Tab and disconnect from PC. Hold volume down and plug into PC to get into download mode. Launch Heimdall-Frontend.exe (drivers should still be installed, if not re-installing the same way from the previous steps will work, but you should not need to do this again). Put your modified zImage in the kernel slot AND recovery and hit start. This will flash a custom kernel AND @khasmek VOODOO recovery! First boot may take a while due to External 4 partition conversion. This is normal. If you bootloop for ANY reason, wipe data and cache. By the way, this kernel is also overclocked to 1.4Ghz. Must use SetCPU otherwise stock speeds of 1Ghz will be default.

*Note: Remember, do not use ROM Manager to flash a recovery or you will have to follow steps 5 on again to restore your Tab (You will have to boot into recovery manually until someone fixes stock ClockworkMod Recovery, I can’t stress enough not to use Rom Manager until you hear otherwise). By the way, these instructions ALSO double as a RESTORATION guide!!! If you get stuck anywhere, past step 5, simply start over at step 5 to recover your Tab. If you get stuck BEFORE step 5, start over at step 1!! Great right?!

then i sucked step 4.
