Ok thanks.
Ik wil niet mierenneuken, maar met flashen bedoel je gewoon de onderstaande stappen?

En het maakt verder niet uit dat die update eigenlijk voor EP30 gebruikers terwijl ik al op FRF91 zit?
1) Ok, now I think you are already enjoying your delicious dessert. Let's add some strawberries to it.
2) Download the PAUL modified FRF50 -> FRF83 zip file from HERE. (In dit geval dan de FRF91 VF)
3) Connect your phone to the USB cable and mount the card.
4) Remove the existing update.zip file from the SDcard.
5) Copy the downloaded FRF83 file into the SDcard's root folder and rename it to "update.zip".
6) Shut down your nexus one.
7) Boot into the boot loader ( Trackball pressed + power button )

Press the power button once ( quickly and for a very short time ).
9) The screen changes and you move to the Fastboot screen.
10) Do Not do anything for about 8-10 seconds. It scans for some files and returns to the "FastBoot Screen"
11) Now use the "volume down" button to select "Recovery" and press the power button.
12) The phone now boots into Recovery.
13) Select "Flash zip from sdcard" and in the next screen select the "update.zip" file
14) Wait for the most annoying 15-25 seconds and reboot.
15) VOILA , you are on the latest and greatest android update for Nexus One!
