Hello there, everyone! It’s been a while.
So, somewhere in the past few days, Google decided to push out a new update for the Nexus S (i9020t) – Android version 2.3.6, build GRK39F. If you’re looking for the full update (from stock 2.3.4 (GRJ22) only), go ahead and grab it directly from Google’s servers.
Anyhow, included in the update, we have a new radio: I9020XXKF1
Since we do not have a full update, the update linked above only contained a patch for I9020XXKD1. As such, I took it upon myself to create a full radio image, ready for flashing with fastboot. This has been tested, and is proven to work. You do not need to be running any specific radio version to update.
The command to update is fastboot flash radio I9020XXKF1.img
You can grab the download here: I9020XXKF1 MD5: 9e0e2086fbc5adcff88e6ca0bfe2d0b8
If anyone would prefer that I package this up in update.zip format, just leave a comment here, and I’ll take care of it.
UPDATE: I have packaged an update.zip for those who wanted it. It is self-signed, so CWM may or may not complain about it. If you have issues, please turn off signature verification.

UPDATE2: These two files differ from the other one that was released. The other one is a straight dump of /dev/block/mtdblock5. It includes about 1.5MB of excess “junk” at the end of the file. This one has been stripped down to the correct length, as per all of the other officially-released full radio images. I’m not saying there is anything wrong with the other release, as it should work just fine. This release just conforms to the format of all previously-released full radio images.
As always, donations are appreciated — I do everything I do free of charge, in the interest of helping others. This is not my job, so anything, $1 or $100 helps. Thanks!
