I am not responsible of any problem you may face using those files. You must know what you are doing when using those files, if you don't, don't use them.

Froyo release FRF85B


Update using official patch file
You must be runnning the stock FRF83 release with stock recovery. Copy that file to the root of your sdcard, rename to update.zip, launch recovery (power on with volume down held), press power and volume up when the warning triangle icon appears then select 'apply update.zip'.

Download: Google

Update.zip to flash with custom recovery

This is the totally stock FRF85B repacked as update.zip. The radio hasn't changed since FRF50, so if you are using it, you can keep it and install the noradio version.

Download:
- without radio image: 4shared - multiupload (md5sum: 239237c5d59ba14d50ca4c3e614e0e13)

Root

To root FRF85, just flash this update.zip (df9bac43866eb048479fa16fa1b559dd) (contains busybox, superuser.apk, su, unsecured boot.img)

I assume that to use this pre-rooted update, you must first unlock your bootloader? Or is this a rooting solution that doesn't require it to be unlocked?

If your phone is unlocked or rooted, follow this one above, If your phone is not rooted, follow the one above that says stock.

The download link isn't working for me. Reports no such file on the server. I'm running FRF83. I updated manually from ERE27 last weekend. I know that my nexus isn't rooted as I checked last week. Is it unlocked though? If i've already carried out these manual updates does that mean that it is unlocked?!

Hopefully if I can get my hands on FRF85b and then FRF91, I'll update this weekend. Any idea's on what's happened to the file in the link at the top of the thread? There's links in other forums which are also reporting broken.
