If you flashed a custom ROM it would have included a recovery. For the N1 simultaneously press VOL Down + Power and HOLD until the white page is displayed then select RECOVERY using the volume buttons and Power button. If it starts to display the boot animation then you missed it and might as well pull the battery and try again.
Rom's don't normally include a custom recovery. In order to have flashed a custom ROM, a custom recovery had to have been flashed first. The stock recovery would not recognize the signature of custom ROM and not allowed you to flash it.
If you have ADB installed and running properly, you will want to try and make sure you flash a custom recovery (just to make sure) and also make sure you can reboot into recovery:
Flashing a custom recovery via ADB from PC:
Download the following files and save them on your PC (which recovery you choose is up to you, but both work and if you ask which is better, you will always get multiple answers. I have used BOTH without any issues):
ClockworkMod Recovery (Pick one and download it):
2.5.0.7
OR
Armon_RA:
1.9.0-Alpha
AND
flash_image
Connect your device via USB to your PC with ADB installed and working:
Open a Command Shell window and make sure you are in the directory you downloaded the files above too and type:
Code:
adb devices (to verify it sees your N1)
adb push flash_image /data/local/tmp/flash_image
([B]IF[/B] the above gives you an error, use: adb push flash_image /system/bin/flash_image)
[B]--For Clockwork:[/B]
adb push /recovery-clockwork-2.5.0.7-passion.img /sdcard//recovery-clockwork-2.5.0.7-passion.img
[B]--For Amon_RA:[/B]
adb push recovery-RA-nexus-v1.9.0-alpha.img /sdcard/recovery-RA-nexus-v1.9.0-alpha.img
adb shell
su
(now you need to change to the directory you pushed flash_image too)
cd /data/local/tmp/
[B][COLOR="Red"]OR[/COLOR][/B]
cd /system/bin/
(make sure your flash_image file is there)
ls -l flash_image
(once verified, do the following)
chmod 755 flash_image
[B]--For Clockwork[/B]
./flash_image recovery /sdcard/recovery-clockwork-2.5.0.7-passion.img
[B]--For Amon_RA[/B]
./flash_image recovery /sdcard/recovery-RA-nexus-v1.9.0-alpha.img
At this point, I would choose a ROM and have it ready. You should try and flash a new radio as well.
Here is the Radio Image for any of the FRG83 based ROM's:
RADIO UPDATE - 4.06.00.12_7 (from Froyo OTA's)
-
4.06.00.12_7_Radio_Update
To copy it to your SD Card, use:
Code:
adb shell
adb push Radio_Update_4.06.00.12_7.zip /sdcard/Radio_Update_4.06.00.12_7.zip
Flash this via recovery (the Radio)
Reboot Into Recovery via command line:
Connect your device via USB to your PC with ADB installed and working:
Code:
adb shell
su
reboot recovery
Once you reboot to recovery, hopefully you will see something on your screen.
Flash the Radio before you try ANYTHING else.
Then flash your ROM.
I hope this helps and works for you.
Thanks,
