Looks like Google moved the file. Hope this doesn’t mean there was a major bug found. http://android.clients.google.com/packages/ota/verizon_prime/12f767e7a5d0.signed-mysid-IMM76K-from-ICL53F.12f767e7.zip
Have no fear though the update I have is uploaded and ready to go here: http://goo.gl/kiGkD
There it is direct from Google. If you are unlocked and got root it’s easy to get it installed but what about those who are locked and unrooted? Here are your instructions.
Follow this video just replace the IMM30B with the new IMM76K
Here is the commands from the video since they are hard to see and links to mempodroid.
https://github.com/saurik/mempodroid Download the pre-compiled file place in the same folder as adb and the update.zip
adb push update.zip /sdcard/update.zip
adb push mempodroid /data/local/tmp
chmod 777 mempodroid
./mempodroid 0xd7f4 0xad4b mount -o remount,rw '' /system [UPDATE: This is 2 single ' quote marks not a double quote mark. Many people it appears are using the double quote and this is kicking them out of the shell. This is an issue with WordPress I have noticed that it is automatically changing the 2 single quotes I typed in to a double quote when it saves. I have used the <code> tag to see if this fixes the issue with WordPress.]
./mempodroid 0xd7f4 0xad4b sh
cat update.zip > /cache/update.zip
adb reboot recovery
To enter the stock recovery press volume up and power once on the open Android Screen.
Some people are having trouble getting from the Android laying down to the recovery options. What has worked for me every time is to press power first then press volume up. I usually have the power button held for about a half a second before pressing volume up. Then use volume down to select the second option and then choose update.zip.
Choose to install update and then pick the update.zip file and wait for the magic.
