Android Market missing from G1

---

My Android G1 was rooted, but it bricked. For some reason none of my backups worked. Thinking that there was a problem with the SD card I reset the phone to factory, reformatted and repartitioned the SD card, and started over. It looked OK, but it turns out that the Android Market is missing.

All of the purchased programs are lost. It also seems that you can't install most programs without Market being installed. When I tracked down and tried to install vending.apk it tells me that it can not be installed on my phone. After some research it seems that you also need gtalkservice.apk, but when I try to download that I get the same error.

I do have a copy of the original working SD card on my computer, but I can't figure out what to move over to recover Market.

I can't imagine why Google would want to make it difficult to restore Market to the phone. The phone isn't very useful without it. Please, if anybody can HELP it would be greatly appreciated.

Have you tried flashing a stock ROM? I don't think restoring factory settings is going to bring back any system files you have deleted, unless there's an image somewhere on the filesystem.

its sluggish naa...
