[Asus  Eee Pad Transformer Prime] sledgie:
Luccid and Roel,

Sorry to hear about the troubles. I feel for you, trust me. I almost lost it when it happened.

I would suggest to try these things.

First, there seems to be something wrong with these primes when it comes to how much your prime is charged. I **only** had success after I drained it completely - the prime would not come on with power button or volume down and power.

I charged it for 30 minutes - when I plugged it in I saw red battery icon charging.

I then disconnected and held volume down and power - I let it boot to 2 options - FULL WIPE or BOOT into ANDROID

At this screen I put paperclip into reset slot. I then followed steps below and got my prime back.

I would suggest charging it for only 30 minutes - DO NOT connect it to your DOCK and charge if you have one.

If you feel you want to bypass this step, try below. If these steps below fail, you might want to let it drain.

Roel, you may need to wait a day until the DE version of .28 is posted before continuing. you can try part A and B but the DE version of .28 is not on Asus yet. I believe if you have a German Prime you need DE version.

Part A.

1. Make sure you know the proper sku for your version - check the post nitram_tpr made above

2. Download .21 firmware from Asus' site or Cky2000's thread (make sure you download the firmware and not the kernel in his thread)

ftp://ftp.asus.com.tw/pub/ASUS/EeePAD/TF201

3. The name of the file should end with UpdateLauncher.zip

4. Unzip the file ending in **UpdateLauncher.zip to the root of your microsd card - it should now end in **9.4.2.21.zip and rename it to EP201_SDUPDATE (it should still retain the .zip extension; make sure it's not EP201_SDUPDATE.zip.zip)

5. It should look like the picture at the end of this post - again, make sure it's in the root directory of the microsd card (for those that don't know, all that the root directory means is the bottom of the tree of directories, i.e., if it would be your C: drive the root would be C:\ or E:\ etc)

6. Your microsd card should now look like the picture at the end of the post

Just to retrace the steps - You downloaded the firmware sku version for your Prime ending in .21 - unzipped the file which produced ANOTHER .zip, renamed it to EP201_SDUPDATE, and stuck the file (still in it's .zip form) to the root directory of your microsd card E:\EP201_SDUPDATE.zip

Part B

**Don't stick the microsd card in your prime yet**

1. Make sure when you hold volume down + power for a few seconds it vibrates and the screen goes off and then on again.

2. Make sure you get the Asus splash screen and then some words at the top after holding those buttons down. I can check right after I write this what it says, but the Prime is the only computer I have and I'm unable to do it right now.

3. DON'T press volume up. Let it boot to 2 options: Complete Wipe of your data or Boot into Android

4. Don't touch anything if you want it to boot into android (otherwise you might ACCIDENTILY WIPE your android)

5. Read #4 again - DON'T TOUCH ANYTHING

6. After it checks through the viability of 2 files it will start to reboot

7. Assuming at this point that it freezes the screen, (you can wait 2 minutes or so) put paperclip into reset button

8. Put microsd card in slot again

8a. Let it freeze on Asus screen again

9. Press Volume down + Power - this time, when Asus Splash Screen shows up, press Volume UP immediately. It should start to boot into recovery

If done properly, Your android will be lying sideways with some nuclear animation going on.

If the status bar boots up and starts accumulating a blue bar - let it finish.

If instead, your Android shows a red exclamation mark goto the last part

Part C

1. Put paperclip into reset slot below microsd card

2. Screen should go black and start to reset

3 Take microsd card out

4. Remove the EP201_SDUPDATE file from the microsd card - whether you put it in your phone or computer you want to delete that EP201 file (as it contains firmware .21)

5. The root directory should have no files in it now

6. Download the .28 sku firmware version

7. Follow the steps above - unzip the **UpdateLauncher file to your microsd root directory (again, look above if you get lost)

8. You should now have a file ending in 9.4.2.28.zip on your microsd card

9. Rename it to EP201_SDUPDATE - again, it should be in root directory and make sure it has .zip extension

9a. It should look like picture at end of post

10. Insert Microsd card into your prime

11. Hold Volume Down + Power

12. Press Volume UP IMMEDIATELY once Asus Splas Screen comes on

13 It should verify the file on your microsd card and start nuclear fission on your android

Please let me know if these steps work. i will do my best to help if people have problems
