ok since there are 5 threads right now on the first page about how to do it and there shouldn't be, this is what you do, i will not link anything to anything because you should be able to find everything pretty easily(they are all stickies)

so all of you that messed something up on your phone and need to get it back into warranty this is how, FOLLOW THESE STEPS:

NOTE: if you have flashed a custom splash screen to splash2 then you will need to erase that before step one with this code
plug phone into usb in fastboot mode
fastboot erase splash2
After that you will have only one splash screen and when you flash the .nbh you will be fine

1. Get the original SPL for your phone, get it here
2. Rename it to and copy it to your sd card. /sdcard
3. Download the DREAIMG.nbh from here.
4. Place DREAIMG.nbh on the root of your SD card. /sdcard
5. Go into your phones recovery. [Hold the home & power button]
6. Push Alt+S on your G1 to flash it with
7. After it does its thing, gettig back to your home screen.
4. Start phone in bootloader. [Hold camera+power button]
5. Hit power to start the update DO NOT INTERRUPT!! i can not stress this enough.
6. Click on the action button(track ball) and your phone will reboot.
7. YOU NOW HAVE STOCK FIRMWARE, it will update on it's own in a little bit, or *Settings>About phone>System Updates*

Just wanted to add one point - I followed this guide, but there's one bit that might not be obvious.

DREAIMG.nbh will restore your phone *mostly* to stock. There's one thing it won't change - the second splash image. If you've changed your splash images, you might want to restore them to stock separately before following these instructions.

Wouldn't be an issue for most users, but in my case the keyboard bit the dust and I had to do a return, and once I set it back to stock I couldn't re-root (and was left returning the phone with a custom second splash image).

i followed all of these steps and as it was applying the dreamimg rc29 for me it said failure... what do i try now? it seems that now my phone will only boot to the multi-colored screen and everytime i try to apply the update it fails about 3/4th of the way through... my phone doesnt work... any thoughts on how to fix this?

you don't need to find the RC30 or RC33 files because when you have the stock RC29 your phone will update on it's own after a few hours. the only thing needed to upgrade to cupcake is the cupcake image. the radio is a choice and you ocan choose not to flash it. i still use the original radio that came on the phone with RC30 simply because i have been too lazy to get the latest radios
