help installing rom

[omega776]

hi there
i am using a android g1
and ive followed these steps to root and flash my phone

1. Format your phone’s SD card to FAT32 mode:
   
   • Hook your phone up to your computer using a USB cable and then wait for the notification to show up in your title bar of your phone.
   • Click the notification, and then click “Mount”.
   • A new removable disk should show up on your computer. Right click it and select Format, and select FAT32 as the file system type.
2. Download and unzip the RC29 or RC7 image file. Copy the DREAMIMG.nbh file to the SD card. (RC29 for US, RC7 is for UK)
3. Turn the device power off.
4. Hold Camera button, and press Power button to entry bootloader mode. You should see a gray/white screen with instructions to flash your phone with the update on your SD card. If you don’t see that, make sure you followed the instructions properly.
5. As per the on-screen instructions, press the Power button to start upgrade procedure. DO NOT DO ANYTHING TO INTERRUPT THIS PROCESS.
6. After it is finished, perform the restart your phone.

Once you are running RC29 firmware:

1. Download recovery.img and copy it to your SD card (see the previous instructions on how to copy from your computer to your Phone’s SD card).
2. Download the Hard SPL and copy the zip file to the SD card.
3. All files must be on the root of your SD card.
4. Restart your phone. Wait for your phone to start up fully and show the home screen.
5. After your phone starts up, hit the enter key twice, type “telnetd” and press enter. (Yes, it will start up a contact search, don’t worry. Just type it.)
6. Download an Android “Telnet” application from the Market and connect to localhost.
7. If you connect successfully, you will have a root prompt “#”.
8. Type the following into Telnet (these commands will give you root access easier in the future):
   
   • mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
   • cd sdcard
   • flash_image recovery recovery.img
   • cat recovery.img > /system/recovery.img

Now you have root!
