Let me see if I understand what you're saying. You successfully got s-on, but are now trying to flash PC36IMG.zip from recovery? That file should be recognized in hboot, not recovery. Or are you still trying to get s-on?
this is how i have done the unrooting process what steps do i not need to do
BEFORE UNROOTING
- Make sure you UNFREEZE any frozen apps with Titanium Backup.
STEP 1: DOWNLOAD
Download both the PC36IMG.zip and the S-On Tool to your PC Desktop. DO NOT EXTRACT
(NOTE: Make sure the file is named PC36IMG.zip exactly. Some Windows OS hide any extensions by default; so make sure it is not named PC36IMG.zip.zip when you rename it.)
STEP 2: MICRO USB
Connect your device to your PC with the Micro USB cord.
STEP 3: DISK DRIVE
Chang your charging options to Disk Drive.
Menu > Setting > Connect to PC > Default Connection Type > Disk Drive > Done
STEP 4: S-ON TOOL TO SDCARD
Transfer unrevoked-forever-son.zip to the ROOT of your SDCard.
(Do not transfer the PC36IMG.zip yet)
STEP 5: TURN OFF DEVICE
Power down the device by holding the Power Button for 2 seconds. Allow it to shutdown completely. Wait about 10 seconds before next step.
STEP 6: RECOVERY MODE
Hold down VOL DOWN + POWER until device boots into a White Screen.
Move to RECOVERY by using the VOL DOWN toggle and select by using POWER button.
STEP 7: FLASH ZIP
Select unrevoked-foreverson.zip in the selection area and press POWER button to complete the FLASH.
STEP 8: IS S-ON, ON?
When the FLASH is complete, Reboot the device into the Bootloader screen by holding down VOL + POWER until it boots into the White Screen. Check to make sure it says S-ON on the TOP. If it does, select RECOVERY with the VOL DOWN toggle. (continue to step 9)
If it says S-OFF, repeat STEPS 5 - 7 until it says S-ON.
STEP 9: TURN OFF DEVICE
Power down the device by holding the Power Button for 2 seconds. Allow it to shutdown completely. Wait about 10 seconds before next step.
STEP 10: RECOVERY MODE
Hold down VOL DOWN + POWER until device boots into a White Screen.
Move to RECOVERY by using the VOL DOWN toggle and select by using POWER button.
STEP 11: TRANSFER PC36IMG.zip TO SDCARD
Connect the MICRO USB Cord. There is an option for this in both the Amon RA and Clockwork recovery.
Transfer the PC36IMG.zip to the ROOT of your SDCard.
STEP 12: UNHOOK USB FROM PC + USB OFF
SAFELY remove the USB from the PC and then turn OFF USB in Recovery.
STEP 9: TURN OFF DEVICE
Power down the device by holding the Power Button for 2 seconds. Allow it to shutdown completely. Wait about 10 seconds before next step.
STEP 10: RECOVERY MODE
Hold down VOL DOWN + POWER until device boots into a White Screen.
Move to RECOVERY by using the VOL DOWN toggle and select by using POWER button.
The Device will check for the PC36IMG.zip and then ask you YES/NO to apply the newly introduced update. Press VOL UP = YES or VOL DOWN = NO.
Once Completed, press VOL UP to reboot.
YOU HAVE JUST BEEN UNROOTED! BAM!
