After downloading these update files, which will be in the ZIP format, you have to follow the steps given below for both of the phones.
- Rename the downloaded file to Update.ZIP [careful if you OS hides files extensions]
- Copy the file to the root of your phone microSD card.
- Power off and then reboot it by holding the Power and Volume Down at the same time.
- Using the Volume keys, navigate to Recovery and press Power.
- Recovery screen will only show a triangle with an exclamation point in it. To get to the recovery menu press Power and Volume Up at the same time. (Keep trying if it doesn’t work the first time)
- Scroll down and select “Apply sdcard:update.zip.” [In Nexus One]/ “Apply update from /sdcard” [In Nexus S] to start the update.
- Let it update your phone, once completed reboot your phone.

What is the root folder on the Nexus One?
@Kiwi Not the root of your phone but your memory card. Just copy the file in sd card, not inside any folders..
I just installed it on my N1. It works 🙂
not been able to reboot it as instructed above. Please help.
I quite not understood “Copy the file to the root of your phone microSD card”
wonder if we have a video showing the manual update process.
Finally why is this update not OTA (auto)?
@amit Just copy the file to sdcard, but do not put in any folder, just paste it outside folders..
NOOOOOOOOOOOBBBBBSSSSS!!!!!!!!!!
Sell your phones and buy envelopes and stamps ASAP.
