    Hello,

    After rooting my Nexus One (with Android 2.2), the display stopped working.
    It shows a black screen.
    The bottom control buttons are working, I can feel the phone vibrating when the buttons are touched and I can modify the volume too, but no image.
    I tried to reinstall the OS with no luck.

    Can anyone help me ?

    P.S.
    The display is not damaged because the fastboot screen shows up when I power on the phone with the trackball.

    I "think" this has to do with radio mismatch. I noticed the exact same thing when I flashed an older stock ROM onto my N1 that had a newer radio. Make sure you meet the radio requirements for the ROM you are trying to install.

    If you need to flash the radio but can't see the screen:

    Download the ZIP file onto your computer. Plug in your USB cable and boot to Recovery (Volume down + Power). From recovery you will need to mount your phone as USB device. I think it is MOUNT USB. Once you see the phone as an external drive on your PC then copy the radio zip to you phone, unmount the USB drive and then choose flash any zip and browse to the radio ZIP on your phone.

    That's my advice I could be wrong but for sure make sure you have the required radio for the ROM your flashing .. Cyanogen needs 12_7 for example.

    Thank you, I will try that.
    I tried to flash a downloaded recovery image but the recovery screen doesn't even show up.

    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 (Text):
    1. adb devices (to verify it sees your N1)
    2. adb push flash_image /data/local/tmp/flash_image
    3. ([B]IF[/B] the above gives you an error, use: adb push flash_image /system/bin/flash_image)
    4. [B]--For Clockwork:[/B]
    5. adb push /recovery-clockwork-2.5.0.7-passion.img /sdcard//recovery-clockwork-2.5.0.7-passion.img
    6. [B]--For Amon_RA:[/B]
    7. adb push recovery-RA-nexus-v1.9.0-alpha.img /sdcard/recovery-RA-nexus-v1.9.0-alpha.img
    8. adb shell
    9. su
    10. (now you need to change to the directory you pushed flash_image too)
    11. cd /data/local/tmp/
    12. [B][COLOR="Red"]OR[/COLOR][/B]
    13. cd /system/bin/
    14. (make sure your flash_image file is there)
    15. ls -l flash_image
    16. (once verified, do the following)
    17. chmod 755 flash_image
    18. [B]--For Clockwork[/B]
    19. ./flash_image recovery /sdcard/recovery-clockwork-2.5.0.7-passion.img
    20. [B]--For Amon_RA[/B]
    21. ./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 (Text):
    1. adb shell
    2. 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 (Text):
    1. adb shell
    2. su
    3. 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,
