    Exclamation I am unable to reboot my TF700T

    I am a new user to this. My transformer pad was working properly and suddenly it stopped. after continuous trial i could switch it on. But the window shows "Key driver not found, Booting OS. when I started pressing the volume down key, installation of software began and suddenly an android guy fell on his back with an error symbol was displayed. What can be done for me to start it normally

    NITHYA, there should be more information on the page that said "key driver not found". You can ignore the "android-cardhu" part, but we need the info about "released by". Mine says "released by US-epad-10.6.1.14.10-20130801 A03" and I need a magnifying glass to read it. It also says "starting fastboot protocol" but we can ignore that for now also. The US part means I have an American unit, yours may be WW (European) or JP (Japan) or a few others, and we absolutely must know which it is. Now, on that page, right in the middle are three icons, one of them flashing. Pressing volume-down will change which one is flashing, recovery (RCK), system (android), or wipe data. As long as you have the stock recovery, and by your description you do, you are safe to try the wipe; press vol-down until that one is flashing, then press vol-up. This actually calls the recovery also, but gives it the additional instruction to wipe your /data partition. Be aware that you will lose all your files, pics, and programs and set the machine back to factory. But it might allow it to start. If not, we'll have to find that SKU (WW, US, whatever) and download the latest firmware from the Asus site, put it on a microSD card, boot the tablet into recovery again and it should flash the new firmware. We'll probably have to unzip and rename the file first. There's a whole section on the procedure in the Master Help Guide, linked in my sig, but try the wipe first, it's much easier.

    @j., NITHYA's description of the dead Droid says that he has the stock recovery, so he certainly has a stock ROM and it's unlikely he's unlocked. And irrelevant unless the standard procedures simply won't work on this tablet. Rare but it happens.

    I went to the Master Help Guide because I am having problems with booting my TF700T. It states Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14, 10-20130801" A03 Key driver not found..booting os
    Starting Fastboot USB download protocal.
    I went to the MHG to download firmware but it states OOPSSS not found. How can I proceed? The tablet just stays on the Asus logo with circle spinning round and round. I cannot even shut it down. I must wait for the battery to lose power

    Well, I suggest you try searching / navigating the Asus site for yourself if you were looking for stock firmware! They don't make it that difficult, y'know, with one Google search for Asus TF700 Support I went straight to the right page. We aren't baby sitters here..

    Asus has been changing their website around, and they don't much care about how easy it is to find old files for the tablets they don't support anymore. Apparently they don't much care about their customers period. But determined searching can get you there as j. just proved.
