No. zip files should be flashed through CWM (or TWRP) but since I am more familiar with CWM I will give you those instructions.
First, get all the files downloaded.
You will need an insecure kernel with CWM. I'd try this one >>
[KERNEL] SpeedMod Captivate [K13E HPCall VoodooSnd7 SharpnessFix STABLE] - xda-developers. Again, there are multiple versions because the assumption is you want it to be compatible with the installed OS, but since we are going to flash CM10 right away, it won't matter. The kernel will be replaced with CM10. Download the latest .tar file (speedmod-kernel-i897-k13e-500hz.tar), not a zip file.
You will need the CM10<whatever>.zip and gapps<whatever>.zip Make sure gapps is for the version of android you are installing. For example if CM10.1 is Android 4.1, make sure you get the gapps for 4.1 and not 2.4 or 4.3.
Copy them to the root of your phone. I assume you can still get your phone to boot and connect to your PC? When you plug it in, and enable storage mode, whatever drive letter is assigned will be the root of your phone. If you can't, then put them on an SD card and put the card in the phone. If you have any important other files on the SD card,
back them up. Flashing shouldn't touch the external card, but you never know.
So ... before you flash copy those two zip files to your phone (CM10 and gapps).
Make sure the phone has at least an 80% charge and the drivers are installed on the PC you re using. Since you already used Odin, I'll assume they worked.
Now we are ready.
Step one. Flashing the new kernel with CWM.
1. Put the phone in download mode. I've always found the easiest way is to pull the battery for a few seconds, then replace it. Hold the vol. up and vol. down buttons and plug in the USB cable. Do not touch the power button. You should see the yellow triangle and the downloading message.
2. Fire up Odin on the PC. Your phone will show up as a number in a yellow box. In
PDA, check the box and select the speedmod-kernel-x-y.tar file. Leave the other settings as default: PHONE, CSC, PIT should be blank and Re-partition should be
un-checked.
3. Click start. Let it complete. It may try to reboot the phone upon completion and fail. No big deal as long as Odin says it completed.
Step Two. Flashing CM10.
1. Shut the phone off and unplug it. If it failed a reboot and is stuck, just pull the battery.
2. Boot into CWM recovery. Press and hold the vol. up and vol. down buttons and press and hold the power button until the screen flashes. Release the power button while continuing to hold the volume buttons. it will boot into recovery.
3. Clean out the old system. First perform a factory data reset. You use the volume keys to highlight the options and the power button to select. There will be several confirmation screens. once completed it will drop you back to the CWM screen. Now select wipe cache partition. Confirm, confirm. Finally select advanced and wipe the Dalvik cache. When that is done select the ****go back **** option to get to the main CWM screen.
4. Now we put in CM10. Select install zip from sdcard. It should take you to the root of the internal data partition so if you copied your files there you will see them. You'll have to scroll with the volume keys as it lists all the folders as well. Try pressing up first to see if it takes you to the bottom of the list. Select the CM10<whatever>.zip file and install ... there will be several confirmations again. It will take a while, be patient. When it's done, flash gapps the exact same way.
5. Reboot. With both CM10 and gapps it should say "completed" when it's done so if you say those you are golden. Just remember, that this is fresh, brand new, never been touched OS so it's initial boot will take a good 10 or 15 minutes to reassemble everything. That's why it was important to make sure the battery had a good charge. If the battery fails during a flash you can brick it.
Once you do it once, it's pretty easy. Don't get discouraged if it doesn't go exactly right the first time. Good luck and let me know if you run into anything.
