Tablet: ASUS TF300T, Unlocked.
SO: Cyanogen 10
Old (working) Recovery ROM: “recovery-jb.img”
New (NOT working) Recovery ROM: “recovery-clockwork-5.5.0.4-tf300t.img”
Keys combination don’t work, just the APX one.
Symptom: the cyanogen didn’t work well so I changed the recovery ROM. As the new Recovery locks when executing from the bootloader, I decided to restart in recovery directly from the cyanogen (power button –>Reset -> Reset into Recovery). VERY BAD IDEA: Now the tablet always tries to start in recovery and gets stuck on the start screen. I can only enter the APX with keys combination. I cant enter boot loader and ATX doesn’t recognize fastboot & adb instructions.
Hi, I believe cyanogen 10 uses a jellybean bootloader and CWM 5.5.0.4 is for an ICS bootloader, so you will need to flash CWM 6.0.2.3 which is for jellybean bootloader.
Have a look at link below and download 'recovery-jb.img' & follow the how to flash.

My cyanogen didn't work fine. When I saw this article I thought that maybe I had installed a wrong ROM so i change it with the instructive one.... bad idea...

I think it goes into APX mode, holding "vol +", the screen remains off but the USB recognizes the APX. What should I do at this point to re install the ROM CWM or enter bootloader? when I go out the APX mode all remains the same, the tablet is still stuck .
Ok I no expert here so anyone else please correct me if I'm wrong.
When you say the USB recognizes APK, do you mean (assuming your running windows) that you can see your tab in device manager - something like 'Asus Android Device - Asus Android Bootloader Interface'
If so try this, open cmd (I always run as admin, don't know if it makes a difference) navigate to your /android-sdk/platform-tools and type
'fastboot -i 0x0B05 device' and hopefully you will get a response about your device (tab). If you do I would assume you could then flash recovery, ie put recovery-jb.img in your platform-tools folder and in cmd type 'fastboot -i 0x0B05 flash recovery recovery-jb.img' once done type 'fastboot -i 0x0B05 reboot' and hopefully all will be good, you may then need to reflash you rom not sure.
If your tab does not show in device manager then I have no idea sorry.
Hope this helps.

Hi! thx for your help. fastboot and adb don't recognize the tablet in APX mode. My PC recognize APX mode. I installed the drivers for APX and I have nvflash ready to work, but it seems to be useless without access to fastboot.

For someone to come up with a solution, Like a NVflash utility for Tf300...
Yeah, but if you want add NVflash support to your tablet, it can't be bricked I'm not quite sure, but you try unpack blob from offical update, and flash all files from unpacked blob (LNX etc.).

The USB icon is gone. I sugguest downloading the correct firmware and flashing it with fastboot.
fastboot flash system blob
Download the correct system firmware, open the zip, open the zip, extract the blob to the same directory as fast boot.

4.2 bootloader does not have USB icon, just plug in USB..
i can get to the bootloader menu but only after typing adb reboot bootloader. and then i tryed flashing the blob using adb fastboot -i 0x0b05 flash system blob and then i get "sending 'system' <799764 KB>..." and it's stuck there.. i left it over 30 mins and still nothing
edit: i somehow managed to flash teh system blob (i tried with te 4.1.1 and the 4.2.2) but after flashing it did the exact same thing.. went to CWM ! i even managed to flash the TWRP.blob, and still the CWM showed up.. i can't figure out how is this even possible :| and from the bootloader menu if i go to boot the android firmware, it almost boots (it goes to the lockscreen for about 2 secs) and then reboots again.. am i wasting my time or should i throw it in the garbage ?
thanks again for trying to help me on this one i really appreciate it !

OK. The bootloader menu you now are seeing is the new 4.2 version. RCK - Android - Wipe Data(do not use wipe data).
When you get into this menu if you leave everything alone your tablet should auto into fastboot - watch the screen - upper left.
With fastboot flash the latest (proper) JB blob for your unit.
Good Luck!

You can't flash anything using adb commands. You need to use fastboot. Look in the forum for the proper procedure and follow the instructions.
Nowhere does it say type "adb fastboot ... anything...."

Here is an example of an adb command that does work to flash twrp with slight modification it will flash stock blob as well.
adb shell
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4 Then reboot to complete installation.
adb reboot
I don't know where you are getting your information but you need a new source.
No one said type adb fastboot they are two different things and each has a specific structure to follow.
If the op can get either fastboot or adb to work I'll gladly provide the proper commands.
then you have the same problem as me and a bunch of other people. The bootloader freezes on the flash command, even though it will show success and stuff. It never flashes.
I can push files with ADB and on reboot the files on gone. Since we can't flash with fastboot. We have to send it in to asus at this point. I got quoted $87 + shipping.
sorry, i meant to say just fastboot. i didn't write adb fastboot.. i've tried everything you guys said, but with no success my last resort is to send it to asus for re-softing. It costs about $80 + shipping. It doesn't sound like a lot of money, but it's a price to pay for stupidness or noobness i just hope they can repair it or otherwise i'll have a very expensive thing on whch to chop onions
thanks again guys for helping me

and now i can't enter fastboot screen (no matter have/not press volumedown+power）
it can only enter recovery but do nothing becasue recovery can‘t mount everything
i have no confidence you will understand my english...
are there other ways enter fastboot？how can i revive it only can use recovery？
many thanks

i did the wipe data in bootloader once
now in recovery mode /adb devices can get it
but in bootloader /fastboot devices can't connect my device now

are there anyway to fix it？

i have the same problem. only i flasher the latest twrp recovery. TWRP 2.4.4.0 Touch Recovery
First, CWM 6.0.2.3 is not compatible with Asus 4.2.1, you should have done a little bit of reading and you would have found this very useful thread http://forum.xda-developers.com/showthread.php?t=2187982 where it explains everything you can possibly know and need about upgrading and flashing recovery and gain root. on 4.2.1
Both of you guys have flashed incompatible recovery versions for your bootloaders and now are stuck, try to access Fastboot, keep trying update your drivers and also check several USB ports because fastboot is your only choice now.

I updated to the newest version from asus site Version WW_V10.6.1.8 and then by mistake flashed the latest version of TWRP recovery. now the tablet is in recovery boot loop. I tried the next command: "adb reboot bootloader" and managed ti get fastboot to work but adb shell does not work.
The weirdest thing is when I press the green android icon in boot loader screen, the system boots normally!!!! but!!! when i do restart it always boots into the twrp screen. the only way to boot the system is with your command. I tried to flash the patched recovery which works with the new firmware (the flash is ok) but i cant pass the recovery screen. How can I get rid of this recovery????
If fastboot is still working ok I would suggest re-flashing the stock 4.2.1 (10.6.1.8) system blob. After doing so you will be completely stock again, so you'll have stock recovery and no root. You can then root again & flash the patched twrp again.
Either of these two threads has the info & commands needed as well as links to the patched twrp for the 4.2.1 bootloader.

If when you flash the system blob via fastboot & you do not get the blue progress bar on the tablet this means that your fastboot is dead with no known fix. This seems to be caused be flashing the incorrect recovery on 4.2.1 (10.6.1.8) bootloader.
To test:
after running the command "fastboot -i 0x0b05 flash system blob" on the command prompt on pc it will say complete but you will get no progress bar on the tablet, after this command run "fastboot reboot" if the tablet does not reboot to this command then you are in the below group sorry.

Sorry to say but no.
The only solution is to replace the motherboard, replace the tablet or send to asus for repair which will cost about the same as a new tablet.
Replacing the motherboard looks like the cheapest way to go as you can pick up a second hand tablet with a broken screen but still has a good motherboard for just over $100 on ebay.

Well that's the thing, you can leave as is but now don't have the option to flash anything else until there is a fix that may or may not come along.
Seeing that you still have a working os it really depends on what you want out of the tab.
It is a very weird issue & I don't believe that the motherboards are actually fried in any way but rather locked up somehow in a conflict between the recovery & bootloader but not sure on that & not sure if there will be a solution for this. So it's really up to you. Sorry I could not be of more help here.

The previous link you were provided only works with stock recovery not cwm or twrp.
The 4.2 bootloader (10.6.?.?.?) does not have a usb icon. When you get to the bootloader press no buttons and wait for notification in the upper left - entering fastboot.

Sounds like you flashed the incorrect twrp for your bootloader, flashing a non-4.2 twrp on a 4.2 bootloader can cause a fastboot flash brick.
Here's a little info about the changes from a 4.1 to a 4.2 bootloader as there have been quite a few bricks here over the last few months.
Still not sure of the exact issue here but seems there was a change in some or all of the partition tables with the 4.2 bootloaders for both 10.6.1.8 & 10.6.1.15.3 and as a result after updating to 4.2 and then flashing TWRP (non-4.2 version) or CWM recovery would give the following outcome when you boot to recovery.
TWRP would ask for a password on boot, you can hit cancel but are left not being able to mount any partition including external apart from possible system.
CWM was the same, unable to mount any partition.
The device will now also likely boot strait to recovery, and if you have not wiped system you will now have to cold boot andriod from now on.
Now the bad part - In about 90% of cases flashing TWRP (non-4.2 version) or CWM would also result in a fastboot flash brick, meaning that some other fastboot commands will work ok, however any fastboot flash command will look to go ok on the command prompt but you will no longer get the blue progress bar on the tablet and nothing will flash to the tablet. So your either stuck with the current os and have to cold boot or if you wiped your system your just stuck.
Only solution so far to this issue is to replace your motherboard. Here's a thread on the issue http://forum.xda-developers.com/show....php?t=2179874
And thus the -4.2 versions of TWRP were made for the 4.2 bootloaders
JB 4.2 bootloaders require the -4.2 versions of twrp
- JB 4.2.1 - 10.6.1.8 = twrp 2.4.4.0-4.2
- JB 4.2.1 - 10.6.1.15.3 = twrp 2.5.0.0-4.2
So if you do not get the blue progress bar on tablet when running a fastboot flash command then sorry to say you have the fastboot flash brick.
There are many many threads/posts on this issue with the above info but still people are not reading, bricking there tablets and creating duplicate upon duplicate threads on this issue, so please look through the threads first, read, read and read some more and if still not sure ask as many questions as you need.
Hope this helps explain what has happened and why the fastboot flash command freezes your tablet.
