I have still not heard back from anybody and I've, of course, followed the directions. Quick posting of the updates online has really made this a much more minor problem than originally, but still . . .

yep it would be good to see some update from Asus on that. I wonder if this will be simple software fix or will it need to be hardware change or replacement....

Predo, just return it for another one. Asus is absolutely useless

Sent through the wormhole from my CoinInserted Sensation OG.

Posted to indicate that, unsurprisingly, my no serial # Prime does not see an update. Instead, I'm seeing the now very familiar "There is no update for your device currently." Hopefully, Asus gets this on the web in short order as they've done before, but I'm still a bit irritated that I not yet received a PM reply or email reply after following the directions.

My US prime went for a trip to RMA and came back with s/n but with build WW (?).
Still can't get OTA eventhough the s/n is now populated ...
this is sad ...

Yep.

Thank god I chose to RMA about a month and a half ago.

Still no fix? Why so stubborn, guys? Just RMA...they did overnight for me. If you moan and complain enough, they will cover shipping both ways. I had a replacement within 3 days with a S/N.

I doubt ASUS will ever release a fix for this. They will likely just sweep it under the carpet. After all, they have like 4 new models of TF coming through the pipeline very soon.

That was my experience, more or less.

i was registering my device yesterday and it wouldnt recognize my serial number. i also noticed the serial number on my device and on the system settings didnt match with the one on the box. so when i tried to register it to get the gps dongle it wouldnt recognize my serial so i tried to contact asus thru the live chat option bt no one would connect to me. so i just left it there and when i tried to register it today it was already registered. asus must have done it automatically. anyone else have the issue with the serial numbers not matching up?

I just sent this to ASUS over my Unknown Serial problem.

---------- Original Message ----------
A Factory Data Reset did not fix the problem. I however, refuse to send my tablet back to a service center to get it fixed. I have ALREADY had to send it in twice. The first time I got a new Transformer Prime to replace the first one. I received said NEW IN-BOX Transformer Prime with a NON-FUNCTIONING LCD Screen. Both of these RMAs took over ONE MONTH COMBINED to complete, not including shipping time only time at the Service Center. Again, the Service Center had my Transformer Prime for over ONE MONTH COMBINED from TWO different RMAs.

Therefore, I say again, I refuse to use such awful RMA services. Fyi, the 2nd RMA was apparently supposed to be prioritized to the highest level, but it took them the SAME amount of time to fix it as my 1st NON-prioritized RMA.

Regards,
XXXXXXX

Ditto. Unlock tool fails. Are we too late in trying to get this resolved?
I thought there were many with the unlock tool problem? I have a serial
number but, evidently it does not matter.

I recently RMA'd mine for this problem...it was received 5/4 by Asus, and as of late last night had a tracking number for the ship back. I'll report here my experience when I get it back, but I dare say there may be hope for a reasonable turnaround for this issue.

If you do RMA, just be sure to photograph and document the tablet before packing and shipping..I used the mailing label they emailed me as a backdrop for all the photos I took of my undamaged, working (except for this issue and BT/Wifi fallout) Prime.

Edit: Prime is back, everything is working well, OTA works...I was able to downgrade from .21 to .15, apply root, save root in rootkeeper, and upgrade back to .21 with root maintained.

I'm very happy right now...

Well it's been quite a voyage..

Got my TF201 returned from RMA yesterday, it works fabulous - let's work it with Unlock Tool.
Gives me unknown error. What could that mean? After some lurking I find my s/n is "unknown". What's that? Maybe it can't authenticate with the Asus servers? After more investigation I find various s/n unknown threads and stumble upon the Ratchet fix for this. Sure I thought.

But Ratchet required root, so first a downgrade (I used 9.4.2.15). Then hard wipe to clean the new firmware from previous garbage data.
Next use mempodroid to gain temporary root access and apply the s/n fix according to the guide.

Allright, serial number pops up in settings.
Let's try OTA and Unlock Tool to confirm success - none work.
Unlock Tool still displays "Unknown error. This may be a network connection issue. please wait and try again later.".

That seems like a short story. Well for documentation here's the howto to what was done:
  • Settings - Applications - Manage - All - DMClient - Force Close/Clear Data/Clear Cache and then reboot. Next, go to Settings - About - Check for update.
  • Soft factory reset - factory reset from within android settings.
  • Hard reset - When device is off perform the following: "vol down+power button" -> "vol down button" -> "choose wipe by toggling with vol down button" -> "confirm by pressing vol up button twice"
  • Manual downgrade - Use Method 2. Downgrades regardless of previous SKU (WW/US/TB etc.) and previous firmware version. Perform a hard reset to cleanup after flash. Enable "USB debugging" under "Developer options" in settings and get familiar with ADB to do this.
  • Fix serial number with Ratchet - Chronologically I used the s/n restore guide here. Since the the TF201 is downgraded, the temporary root exploit described in the guide will work.
  • root - (Optional) - It was attempted simply because it was possible at this stage, although futile if the next step is performed, even with OTA Rootkeeper.
    (Choose (1) or (2))
  • (1)Manual update - make sure SKU of new firmware matches currently possessed SKU. Any root access after performing this step is gone.
  • (2)Manual update and keep root without s/n - (Experimental) - Apparently some people have attempted to manually write the incremental OTA Updates to /cache/ partition and force update - thereby keeping root. However, even by reading the posts I cannot grasp how, and it was a heart-attack inducing experience. Not recommended.

I have tried the above with "US_epad-user-9.4.2.15" and "WW_epad-user-9.4.2.11" downgrades, upon which I upgraded them to their corresponding SKU (important).
Beginning the attempts with "WW_epad-user-9.4.2.21" I now rest on "US_epad-user-9.4.2.15".

Maybe this will work for somebody, it did not for me, but I am far from being bricked and await another RMA to resolve the issue. I am incredibly happy with Asus' support and what they do for the community. A sincere thank you to Gary Key who kindly forwarded me to some very knowledgeable people.

Hope this is of use to somebody!

Yeah I have done the exact same thing and I also got exactly the same problem as you. My prime has been RMAd twice and it still does not work. I don´t think asus has handled this very smooth. Im still looking for a solution.

    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 :

    Subject: <TF201 SN Not Found – Your Contact Name>

    Body:
    Name: Your Customer Name
    Phone: A contact phone number
    Email: Your Email address
    SN#: Your TF201 Serial Number

    A customer care representative or technician will take your information, confirm the status of the serial number on our server, ask you to walk through a short procedure to correct the problem. If this fix does not work they will walk you through the next series of steps to correct it.

    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:

    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 :

    Subject: <TF201 SN Not Found – Your Contact Name>

    Body:
    Name: Your Customer Name
    Phone: A contact phone number
    Email: Your Email address
    SN#: Your TF201 Serial Number
    Process Already Completed - Manual Firmware Update to latest ICS ROM Image

    A customer care representative or technician will confirm the status of the serial number on our server, contact you and might ask you to walk through a short procedure to correct the problem. If the serial number is not located, the unit will need to be returned for a replacement procedure.

    2/12/2012 Update -
    If North American users are still experiencing the Serial Number Not Found Problem after completing a manual update to ICS, then please send your contact information and serial number to tablet@asus.com. If you do not hear back from Service within 48 hours, please PM me directly.

    3/6/2012 Update:
    I am back and will start answering messages.

    Note - For those users who provided this information already based on direct contact from us, you will be notified shortly. For those users who provided their serial numbers but were not contacted by us for further testing you will need to either send the email above or call the hotline. We sincerely apologize about this inconvenience but your TF201 will be fixed shortly.

    Gary Is it a software problem or a hardware problem?

    At this point, thanks to the users who reported their serial numbers we think it is probably a software fix as those serial numbers are being seen on our server side and available for a OTA update. Either way, we will take care of those users with this problem. I will be contacting these users shortly for additional information to confirm our findings and solution.

    For all of you watching this thread I thought I'd let you know that it looks like the ICS update has been posted to the ASUS site for download. I'm going to go ahead and give it a go. I'll post back with results to see if the unknown serial number stops the manual update for ICS. I had good luck with the 8.8.3.33 update so I don't see why this one won't work. Don't get me wrong, I want the OTA problem solved but I'll take the manual update for now if I can get it.

    That's not for an uber-newb as there seems to be a lot of pre-steps and things to download, e.g., and which appear to need other things loaded first.

    I'm asking for a walk through for a literal no nothing whose first experience of android is the ATP--there's a lot of us on this site.

    But if this kind of thing is beyond us--well, thanks for your efforts, but we'll have to wait.

    1. If you have a windows pc, download the USB drivers from HERE (choose Android as OS) and install them
    2. Get adb from here: Windows* or Linux
    3. Activate USB debugging mode on your prime (Settings -> Developer options) and connect your Prime to the pc
    4. open a terminal window on your pc
    5. in that terminal window, browse to the directory where you have downloaded adb to (the Ratchet archive should be extracted to the same directory) and execute the following commands:
    6. adb push mempodroid /data/local/ (on linux: ./adb ....)
    7. adb push ratchet /data/local/
    8. adb shell (You’ll now see a shell@android:/ $ prompt)
    9. chmod 755 /data/local/mempodroid /data/local/ratchet
    10. /data/local/mempodroid 0xd9ec 0xaf47 /data/local/ratchet
    11. This is where the magic happens. Make sure you enter your serial number correctly, all in caps!
    12. Reboot your device
    13. Done

    * Download for windows version two post later

    Points 6 to 13 are just copied from the android.mobi website so I don't take any responsibilities.
