Just to let people know, vodafone nexus ones now come with froyo pre-installed. I bought one a couple of weeks ago and tried to follow this guide to get rid of vodafones version of froyo and change to google’s standard version. I wanted to do this in order to recieve future over the air updates straight away from google, instead of waiting for vodafone to put out their own version.

HOWEVER, if you have a vodafone nexus one with froyo pre-installed out of the box, you will not be able to follow this guide fully until you change the HBOOT version of the phone from 0.35.0017 (vodafone’s) to 0.33.0012 (google’s). Guide here:

http://forum.xda-developers.com/showthread.php?t=726258

It involves downloading the Android SDK development kit, using superboot to root to a insecure ROM, changing a few things, then finally going back to a completely stock ROM, HBOOT and Radio version using this guide. It may be a little complicated, but I have done it and it does work. I am now on google’s FRF91 froyo, and first in line for the next version of android. Thanks vodafone :-s

Just to add, thanks for this, like others have reported after going to ERD79, I turned on wifi, checked for updates, and 2.2 was already downloading. That’s in an ex-Vodafone N1 without a SIM card in. So to recap:-

- install usb driver from android sdk on your pc
- unlock bootloader. At this point I had a disconcerting error message: FAILED (status read failed (Too many links)) but the handset appeared OK.
- followed instructions to get ERD79 flashed onto N1
- ensured WiFi was on, went to phone dialler and typed *#*#2432546#*#* -dont know if this step is essential
- went to check for updates.. N1 was already downloading 2.2
- followed on screen instructions, happy days

there is another way to get froyo without rooting instructions can be found at this link belwo .I have also copied the instruction below just incase you cant access it

http://forum.vodafone.co.uk/topic/61110-google-nexus-one-android-22-froyo/page__st__940

two things to be wary off before you go ahead
language screen, will be in Korean until you change it to English
ALSO, It does come with a new HBOOT that prevents downgrading apparently though.

This is the korean update gets Froyo with no rooting!

No, it does not require to root your phone and its quite easy actually:

1. download http://android.smart…ease_signed.zip

2. rename it to “passimg.zip”

3. copy it to your sd card in your N1

4. turn off the phone

5. turn on the phone again while holding the trackball, too

6. select Bootloader (control with volume up/down to go up/down and the on/off button to confirm)

7. the N1 will recognise the file as an update, it checks the file and will ask you whether you want to update or not

8. select update

9. wait until the update is completed

10. enjoy froyo
note: all of your data on the phone itself (not the sd card) will be deleted. so better backup before you install froyo.

Hi,

what if I want to switch to Cyanogenmod 6.0 from EPF30?

Bye,

I’m no expert but here’s what I did

1. Created a folder on my desktop called Fastboot

2. Downloaded Fastboot and unzipped it into my Fastboot folder.

3. Downloaded the ERD79 zip file and put it in my Fastboot folder.

4. Downloaded and installed Ez7z

5. Used Ez7z to unzip the ERD79 file into my Fastboot folder.

6. Opened the terminal application.

7. used cd Desktop/Fastboot to go to the correct location.

After that I just used the commands shown in the article to unlock the bootloader and install the ERD79 image

The really nice thing was, after I had put ERD79 on the phone, it automatically started downloading 2.2 so I didn’t have to do any of the other steps

Cheers Chris for the helpful info about the ez7z unzipper.

Im on mac as well and this process for me has been some what of a hardship and you just help solve one of my problems but I am still getting “error cannot load userdata.img”

What Directory did you use when you were doing step 2, did you just do it on the desktop? did you receive this message at all before you solved the issue? Thats where I am right now and I cant seem to get over this hump. I can erase the cache just fine.

If you have any info on this that would be great!
