    It might be useful to know approximately how long flashing the recovery image should take. I have:

    sending ‘recovery’ (5306 KB)… OKAY [ 7.040s]
    writing ‘recovery’….

    and 10 minutes later nothing has happened. I suspect there’s a problem but it would be good to *know* I’ve been waiting too long.

      If the process is stuck somewhere, restart the entire process.

      You have to replace the -i 0x0B05 with the image of your device. Mine was actually 00000, so I used:
      fastboot -i 00000 flash recovery recovery.img

    when i try it … it says waiting for device y cant it find the asus

      Have you installed drivers for your device? Your PC won’t be able to recognize your device if you haven’t installed the device drivers.

      Please get the drivers first and then follow the procedure.

  • will this work on the jellybean updated version?

  • jordi

    if i do this and then reset default settings like what with the iPhone will I lose the warranty?

    Mahesh, I followed your steps to install CWM on my Asus TF300T. I have Jelly Bean 4.2 and the latest build. I was able to successfully install CWM on the tablet but when I try to do the root install from the recovery menu all I get are erros “Can’t mount /sdcard/ and “Can’t mount /emmc/”. Any suggestions?

    • same here

        Same here, didn’t find a solution for CWM. Only way is to use latest TWRP, unfortunateoly i repair tf300t with broken touch and can’t actually do it 🙁

    This doesn’t work I have 4.2.1. The adb drivers work as my pc can see the serial number of the asus.This is unlocked. When I reboot the asus using power/vol down the asus comes up with a missing valid driver and says booting to usb fast boot and then gives me the options of rck droid or wipe. But when I type the fast boot instructions on the pc nothing happens to the tf300t. ?????Suggestions?????

    So I unlocked with Asus unlock utilities. Running 4.2.1 on my tf300t. Then installed cwm Then like a tool, I factory reset from CWM. I now cannot mount SD card, I cant Mount MMC, and I cant sidemount. This CWM wont mount anything and thus I cannot load a Rom. My tablet loads to CWM and that’s it. I notified ASUS who quoted me at $288 for repair. As this is crazy, Im looking for any solutions. Suggestions welcome and appreciated. Thank you.
