    Hi Set,

    I was epf21b build so can't say 100%, but I 95% believe it will, and here's why:

    Your phone has certain partitions - system, cache, recovery.
    By flashing an ERD79 recovery image to your phone, you are overwriting the stock epf30 recovery build, so then when you run the recovery boot on your phone, it will remove build epf30 and install erd79 (which is the 2.1 stock US build). This will then get rid of the problem where the frf85 update isn't being recognized, as the signature file for the update 'matches' the new build it sees on your phone.

    Oh, and by the way, when you have manually updated, you WILL be able to receive OTA updates, as I received my frf91 update OTA this morning!

    Once i get past this hurdle, it should be plain sailing. Can anyone help me jump over it?
    Should be pretty straightforward and you won't need to flash an entire stock US 2.1 ROM build before updating to 2.2, you just need to flash into your N1 a small file (2MB long) named recovery.img taken from one of those US builds (e.g. ERD79).

    The line-command fastboot is only used in the process to unlock the bootloader and to flash the new recovery image file (recovery.img). Please see below:

    1. Unlock the bootloader.
    DOS Command is: fastboot -windows oem unlock

    2. Flash a recovery image from a different stock build (e.g. ERD79)
    Filename is: recovery.img
    DOS Command is: fastboot flash recovery recovery.img

    3. Copy the file "signed-passion-ota-42745.dc39ca1f.zip" to the root of you SD card, and rename it to update.zip

    4
    . Power-off your Nexus One. Boot into fastboot by holding down the tracker ball and then pressing on the power button.

    5. Choose "BOOTLOADER" by pressing the power button. This should then show you a screen with *** UNLOCKED *** in the top left corner.

    6. Press Volume Down button, so you highlight "RECOVERY" and press the Power Button. You should seen the X logo with the unlocked padlock beneath, shortly followed by a triangle with an exclamation mark and a small green android to the bottom right.

    7. Now press at the same time Volume Up and Power Button. You should now be presented with the "Android system recovery <3e>" page

    8. First, do a "wipe cache partition", then do a "wipe data/factory reset".

    9. Finally: "apply sdcard:update.zip"... It will take a few minutes and will reboot a couple of times.

    10. Ta-daaaaaaaaaaa... FroYo 2.2 FRF85B! :D
    Ok so i want to give this a go, but this means not a lot to me, does anyone know a really idiots guide

    Set, have a look at the link I gave a few threads back. It points you in the right direction and gives you links to everything you need to download.

    Set,

    Looked at that guide you posted and it looks really good. I'm going to transfer some of the text onto this thread.

    ok got through that problem but now i have another, when i do the dos command to use the fastboot i get an error window pop up.

    The program can't start because AdbWinApi.dll is missing from your computer
