What is FRF91? [UPDATED]


Reports on Twitter and XDA-Developers indicate that yet another Froyo build is going out to Nexus One users today, this one with build number FRF91. One person on the XDA thread noted that it was an update from the most recent build, FRF85B. Others report receiving it on both T-Mobile and AT&T versions of the Nexus One.

This is somewhat mysterious and unexpected given Google’s announcement earlier in the week that the FRF85B OTA was the official release. Did they find a bug of some kind in FRF85B that they’ve corrected?

We’ll update this post with more information as we find it. Let us know in the comments if you’ve received this update.

Update: Here’s the direct link to download it from Google’s servers and install it manually, if you’re into that sort of thing. It should work only if you’re already running FRF85B

Update again: Here’s another direct link to the version that will take you from FRF83 to FRF91. We’re hearing now that this is a security update of some kind, specifically aimed at the Gmail app, though that has not been confirmed by Google as far as we know.

Update one more time: Thanks to commenters Echtelion and YsSRS, here’s a direct link to go from FRF50 to FRF91. Anybody got the version for FRF72?


  1. I am curious as to what mode the phone needs to be to receive an OTA. Does it have to be plugged in to a charger or just been "on" is enough?

  2. nexus1 tmobile Tenn/ No OTA, still on ere27. Giving it one more day before flashing since they did say by the end of the week… @eliseo as long as you have some sort of data connection you will get it, assuming they are sending it.

  3. Androidguys, just wanted to let you know that most of the posts I've seen today in Google reader have missing images. Just letting you know.

  4. I manually updated to FRF85B the other day. But I don't know what this new one is about. I am waiting till tomorrow to see if I want to do a manual for that one too. Anyone who has it, can you comment on the specs or differences? Thanks

  5. 910kb froyo patch?
    I am afraid to install it for fear that 85b is the leet boot loader unlock haxor pwn rom and 91 is the patch to fix it . Anyone with 91 know wtf this is supposed to patch? fuck security lol i want teh h4x!1

  6. Just manually update. Have yet to receive an OTA update. Manually updated all the way up to this. This final update is very surprising. Thought Google was done.

  7. I reckon it is because of the screen issues many are experience on FRF85B. Also happens when viewing embedded Flash movies from standard browser.

  8. Manually updated to 85B when it was released. Just got my first OTA to 91 all the way out in Afghanistan on my unlocked N1 (no mods, purchased unlocked direct from Google).
