Hola
Vas aquí:

Te bajas la última versión de la 4.1.1 que es la V10.4.4.25 (fíjate bien si la tuya es la WW o la US) y sigues estas instrucciones:
2. Decompress downloaded .zip file (it will be another .zip)
3. Rename it to:
A. For the TF700 and TF300: EP201_768_SDUPDATE.zip
4. Make sure your MicroSD card is formatted Fat32. It must be Fat32 Format or it will not work.
5. Copy the file to (the root directory of) your MicroSD
6. Insert the MicroSD into the tablet
7. Shutdown (power off) the tablet
8. Power it on by pressing and holding VOLUME DOWN and POWER buttons simultaneously
9. When you see white text in the top left corner of the screen, release the buttons ^^ and press VOLUME UP button (on RCK, this is your recovery which should already be selected) until you see Android logo and process bar
10. Give the update process 5-10 minutes. It should not take longer than that. If it happens to run for more than 45 minutes to an hour, force shut down the tablet and see if it boots. If it does not, try rerunning steps 7-9.
Has probado eso???
Supongo que para esto tienes que poner de nuevo el recovery original!! que en XDA puedes encontrar como hacerlo:

Como te digo todo esto son suposiciones y evidentemente no me lo he leido, asi que utiliza la información bajo tu responsabilidad.
