[Asus  Eee Pad Transformer Prime] Gary Key:
Good Day,

For those users who are suffering from the "Serial Number Not Found" problem we are currently trying to replicate the problem. In the meantime, there has been some success following these instructions.

Issue -

1. System will not auto or manual update to the latest firmware or image.

a. Go to Settings, Backup and Reset, start a Factory Data Reset. Please do this and after the reset let the unit remain active (settings, display, sleep, always on) for 15 minutes with a WiFi connection active so the system can sync with the ASUS servers. Hopefully the system will see the update, if not please go to settings, About Tablet, and then double tap on System Firmware Update please.

b. Alternative Version until the Service Side Fix is implemented.

There is an alternative way to get the updated firmware on your unit.

Ensure you have a micro-sd card available for this update, please download from a PC the US (WW/TW released also) firmware for the device. Please verify that your firmware is US (or WW/TW). In the SETTING and ABOUT TABLET it will tell you in the About section.

Example: You should be able to see the build number US_epad-9.X.X.X_2012xxxx where "US" means build type.

You can download the correct update file from the support site on the below link.

http://support.asus.com/Download.as...cher.zip#US_epaduser9_4_2_7UpdateLauncher.zip

Extract the zip file to the root of your Micro-Sd. It should be the file US_epad-user-9.4.2.7.zip for the US version as an example.

Ensure the AC adapter is plugged in, all apps are closed and you are at the desktop screen, install the micro-SD card and you will get a notification on the bottom task bar to update the firmware. Please follow the instructions.

If that does not work, please PM the serial number of your unit.

1/16/12 Update - We have replicated this problem and hopefully we will have a solution shortly.

1/17/12 Update - Thank you to the users I reached out to for their contact information. You should hear from our engineering or technical support staff shortly to verify a few settings and to try another OTA update sequence. For those I did not contact yet, we might expand the group for additional testing. I have read all the messages so please do not be upset if we have not contacted you yet. We are very close to finalizing a fix for this problem but first we will have to confirm your unit setup.

1/18/12 Update - Technical Support and Engineering will contact another subset of users starting today. We are in the final process of testing two solutions to this problem.

1/19/12 Update - We are finalizing testing with the last subset of users and will post instructions on the fix in the near future. Just a reminder, for those I or engineering did not contact directly yet, it does not mean we are ignoring your problem. We have read all the messages so please do not be upset if we have not contacted you yet.

1/21/12 Update - I will have updates tomorrow and a new communication system with forum members headed up by a dedicated staff.

1/22/12 Update - I will provide an update tomorrow on our new Customer Service Support program for the Transformer Prime and additional forum support that will be coming in the very near future. In addition, I expect an update from engineering and service shortly for the resolution on this issue. We have completed replication testing.

1/23/12 Update -

For North American users with the Serial Number Not Found problem that we have not directly contacted during the replication testing cycle we ask that you please send the following information to tablet@asus.com :

1/25/12 Update -

One option to fix this problem is to complete a manual update process, set the unit power mode to balanced performance and screen brightness manually to 50%, and then manually update to the latest ICS build using these instructions - http://service.asus.com/TF201_fwupdate. You will need a fully charged battery and have the system plugged into AC power. After the update is completed, please ensure there is a WiFi connection available and let the system idle with an active WiFi connection (ensure the system does not go to sleep) for 15~20 minutes and then reboot. If the serial number is not available after this process, please follow these instructions:
