Tring to Reset my N1 back to factory

[Guest millerliteguy]

I need some help I go thru all the steps on http://forum.xda-developers.com/showthread.php?t=614850

but i cant figure out step #8 how do i do that in the command prompt im using windows. I Downloaded the file unzipped it to c:\kevin, what do i type in the command prompt to get there and be able to use fastboot. Any help please

I have done a data wipe and now have no phone..My wife is going to kill me if I don't fix this.

This will do the followings to your Nexus One:

1. Reset your system files to the original system files.

2. Reset your kernel/boot image to the original shipping boot image.

3. Reset your recovery to original recovery (if you wish).

This will not relock your Nexus One. Once you unlock your phone, you are stuck for now.

This is for those of you who decided to flash a few different ROMs and want to restart from scratch.

You may get the Original Shipping Image from HERE or thru Modaco HERE. [22607 build]

MD5sum for the images is: bef86698cafc88ca03fff5758571d9d6 (per DroidDrop)

As before, if you mess up your phone or your computer, you are on your own. I take no responsibility on what you do with your phone or your computer.

Step 1. Disable backup my settings under privacy settings.

Step 2. unzip the original shipping ROM and put it somewhere you can find.

Step 3. Plug in Nexus One with USB to computer (enable usb and debug modes)

Step 4. adb reboot bootloader (which will boot into the bootloader)

Step 5. Confirm fastboot connection fastboot devices

Step 6*. fastboot erase userdata

Step 7*. fastboot erase cache

*If step 6 and 7 does not work, and if you have Amon_RA's recovery installed, you can do a factory data wipe from there.

Alternately, you can also do a factory data wipe within Android. Settings => Privacy Settings => Factory Data Reset.

Thanks to Brian and setzer715.

Step 8. Go to the directory that you stored your unzipped files.

Step 9. fastboot flash userdata userdata.img

Step 10. fastboot flash boot boot.img

Step 11. fastboot flash system system.img

Step 12. Skip to step 13 if you want to keep recovery (assuming you have a modified recovery such as Amon_RA's recovery). If not fastboot flash recovery recovery.img

Step 13. fastboot reboot

Step 14. After the system boots up and while setting up skip setting up with the google account and you can setup accounts later. This will prevent the phone from pulling down the previous settings (downloaded apps, wallpaper etc) from google.

Step 15. You are done. Enjoy.

Ok,

here is what you need to do:

After you unzip the archive, you will get 10 files (8 image files, 1 txt and 1 NB0)

Place all the files under android-sdk-windows/tools

reboot in fastboot, power off your N1, press and hold trackball + power, connect your device

bring command prompt window and point to your android-sdk-windows/tools folder ( you should have fastboot placed there as well)

type in cmd "fastboot devices" to confirm your device is connected

"fastboot erase userdata" --> to delete your userdata

"fastboot erase cache" --> to delete cache

"fastboot flash userdata userdata.img" --> this will flash the stock userdata

"fastboot flash boot boot.img"

"fastboot flash system system.img"

"fastboot flash recovery recovery.img" --> this point is critical, if you want to restore to stock recovery, flash the recovery.img, otherwise skip this step if you wish to use custom recovery

"fastboot reboot"

if you flash all above including stock recovery, this will revert your N1 back to shipping condition with Android 2.1, after that you will be able to get OTA update 1 on 2.1 and you can flash the original FroYo ROM.

As there are already custom FroYo ROM's available, you can either keep custom recovery or use the stock recovery, up to you.

Important is to have all the *.img files from archive extracted to android-sdk-windows/tools to be able to flash them (I mean this is the easiest way to do so)

ENJOY and let me know if you still have issues

Double check your boot.img file is in same folder where the rest image files are

[Guest bluepenny65]

I had all those problems.....and after I got tired.....I just simply installed the ERD27 original stock (see modaco's N1 page)....then flashed this Modaco's http://android.modaco.com/content/google-n...ted-update-zip/ and now I am on Froyo.
