I'll try to help answer as many of your questions that I can.

0) I never used wizbackup as I had nothing to backup. All the official ROM's are readily available if I ever want to go back to them. But here is the link to the wizbackup.exe download: http://xdaforums.com/download.php?id=12373

1) Yes you have a G3 Chipset

2) Yup

3) Yes

4) Yes

5) It will be in the LokiWiz folder, which you just extracted on your C:Drive

6) You place the cab file to your Device, when you have ActiveSync connected to your device. Just go to the "Files" folder on your Sync screen, and select add, and add it. Once you added it, ON YOUR DEVICE, go to Start --> Programs ---> File Explorer --> And double click on the enablerapi.cab file. If you get a prompt that asks you where to install it to, make sure you chose "Device" and not Ext ROM or Memory Card.

7) Make sure you have an ActiveSync connection still. Just follow the prompts on the command prompt screen after you run lokiwiz.bat. If you want to familiarize yourself with it, run the lokiwiz.bat just by itself when there is nothing connected, just to take a look at what the screen looks like. Now, don't run lokiwiz by clicking on the lokiwiz.bat icon in windows. Instead, open a shell on your computer (Start->Run->cmd.exe) and run the program by going into its folder; this way the shell window won't close automatically after the process and you'll be able to read any messages or error messages Lokiwiz is giving you. Here are the steps:

Open a shell (on your computer): Start -> Run -> cmd.exe

- Write: 'cd c:\lokiwiz02b' (without quotes), then press enter. Now you're in c:\Lokiwiz02b

- Make sure you have an activesync connection

- In the shell, write: 'lokiwiz.bat' (without quotes), press enter.

JUst follow the prompts then. "U" is to unlock the SIM. Which is what I did first. After it finished running, it automatically rebooted my device. I then followed Step 7 again, to get back to the lokiwiz screen, and entered "C", to CID unlock the device. It once again rebooted. Anytime it reboots, it will take some time. I looked at the IPL and SPL to make sure that it matched. If it doesnt match, then reinstall the ROM like in Step 2. That should make the numbers match.

8 It should be found in the same Lokiwiz folder on your C:Drive. After you SIM unlock, just make sure to look into that folder to see that you have a "lock_backup.bin" and a "unlocked.bin" file. I created a new folder named "sim unlock backup" and placed them in that. Same process after unlocking the CID. " I created and placed them in a "cid unlock backup" folder.

9) Cant help you there, as I am still looking for a good, fast, clean rom to update to.

10) No problem. I just did this a couple of days ago with the help of Dr. Puttingham and Faria's guide. It's just like he said, "If you follow every step it will work!"

If you come across any error messages, make sure to take a screenshot and post em. On WindowsXP, if you go to the "PrintScrn" button on your keyboard, and then open up MSPaint and click "edit" and "paste", you will have a screenshot which you can save and post. Good luck! You'll be fine!
