[Guide] Fool Proof and Simple FroYo 2.2 "Test ROM" Guide for Rooted Phones

[Paul22000]

1. Download files and place on SD card:
   
   update-nexusone-FRF50-noradio-signed.zip from Modaco.com (May 24: noradio files added - should work fine for T-Mo & AT&T!)
   
   froyo-rooter-signed.zip from Cyanogen
   
2. Titanium Backup -> Backup all user apps
3. Turn off phone -> Hold Volume Down, then Press Power button
4. Enter Recovery
5. Backup/Restore -> Nand backup
6. Wipe if you have a Sense UI ROM (no wipe needed coming from Cyanogen)
7. Flash update-nexusone-FRF50-signed.zip
8. Reboot, you'll get Android-falling-out-of-box
9. It will reboot into Recovery, select Reboot again
10. It should boot into 2.2, yay!
11. You should still have root, but if you want BusyBox (or lost root somehow), Cyanogen has done it again! Go back into Recovery and flash froyo-rooter-signed.zip. Then Titanium Backup will work once again.

I got that while the radio was updating, it should boot back into the recovery menu then reboot once more for FroYo

It worked! this is my first time doing this, so i got scared of the open box based on Paul's 100% fool proof guide

Yep! When it reboots to recovery, reboot again. Updated OP

Freaking sweet! I lost root for whatever reason. Glad to see that Paul and Cyanogen pumped this stuff out! And a flashing I will go!

My flash runs like crap unfortunately. I am getting some FCs too on SMSing apps

Does this work on AT&T devices?

I think only if you're rooted. I'm not sure.

AT&T users in the Modaco thread have said it worked. Here's one poster who's done it:

Post #76:

I think you can just not flash the radio, I do have an AT&T frequency too so I am not taking chance, I will remove the radio.img prior to install

don't worry about it. Just flash it. You'll get a speed bump. I did. Getting about 1mb faster DL speeds. Its crazy... especially since its mid-day saturday. I'm on ATT 3g in chicago.

Though as the previous person said, you may have to remove the radio.img in the zip. I'm totally not sure. Has anyone here done it?

It should work on any rooted Nexus handset.

People are saying in this thread that it DOES indeed work!

so when updating to froyo does rooted nexus one becomes just like the stock one, means do we need to root it again to install custom Rom

 

[MikeLarryML]

Thank you. This is awesome and super easy to execute. Thanks again.

 

[h2opoloplyr_11]

Nice! thanks for the write up.

one thing that confuses me though, i have rooted my phone but have the stock rom (nadroid from cyanogen 506), will i be able to get the OTA when it rolls for the ATT version? Or only manual update for me?

thanks.

Everything works, great post by paul as usual

I followed these steps (was running Cyanogen 5.0.6) and it works perfectly. I have the AT&T/Rogers version. I didn't wipe and all my apps/settings are intact!
