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?

      thanx about to install

  • Chris

    I just got it. Security fix.

  • Still rocking FRF83, which I pushed myself and didn't get OTA 🙁

  • Julius

    still no FRF85B OTA to my N1… : /

    • epgomez

      you can do a manual install. its not hard

      • Julius

        Is there a FRF85B file or must it be 3 installs?

        • Julius

          FRF92 Arrived on Sat… wooo!

  • Eliseo

    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?

    • MaxLaw843

      Just 'On" is all that I have needed for the two OTAs this week on my N1 on T-mobile.

  • fullmetalg

    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.

  • jusblase

    just installed it now am not seeing some apps

  • Matt M

    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.

  • 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

  • It appears to fix security issue with the gmail. app

  • nub-a-dub-nub

    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

  • larvs

    hold out on manually installing 85b from ere27. i got SMS sending issues when i did.

  • 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.

  • lolobabes

    Just received another OTA update FRF91, I love my N1,Philippines… ahihihihi http://twitpic.com/21o5da

  • Steve

    just recieved frf91 after manualy upgrading to fef83 a week ago

  • GingerbreadMan

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

  • I got the FRF91 OTA just a few minutes ago. Mentioned something about a security fix when I downloaded it.

    Just got FRF91 this morning at 7 AM Central time….Chicago!

  • FRF91 manually installed on unlocked but other stock Nexus One in the UK, working great with zero iDefects 😉

  • Todd

    I'm on AT&T (used SIM from a iPhone), and still no 85B or 91. 🙁 I didn't want to take the time to do it manually.

    • Todd

      Still no update. Was I supposed to "register" my Nexus One with AT&T in order to get updates?

      • Todd

        Came today after dialing *#*#CHECKIN#*#*. It's noticeably faster.

  • Ray

    I'm on AT&T (crap) as well and am still stuck at EPE54B (also a used SIM from a Blackberry).


    Just got FRF91.. runs great!! And uses 3 times less memory than 2.1

  • Manual update of Android Froyo FRF91 over my manual install of FRF85B (unlocked Nexus One on T-Mobile) worked fine. Took 5 minutes, tops.

  • Andrew

    Recieved FRF91 This morning, 8AM EST, probably came earlier, but that's when i checked my phone.

  • OTA update from 85 to 91. 1AM +0800

  • Chris

    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).

  • digidop
  • I'm curious about this app.

  • I updated it with no problems. Peter, Koowie.com
