i rooted my tf300 when on stock ics. i used the method that doesnt require bootloader unlocking.
couple of days later the jb ota came along, so installed that, and restored root with voodoo
i want to install a custom rom, but i can't get the recovery working. the tablet boots fine, and the behaviour is the same now im on jb, as it was when on ics
basically, i power on + vol down, then select the rck icon, and it loads to an android with a blue loading animation, then changes to a 'dead' android with a red exclamation just above.
the tablet still boots fine otherwise.
question is, do i have to unlock the bootloader before i can install/run the recovery, or is there a way i can do it without unlocking?
edit: i tried also flashing via fastboot (tried first with terminal, when trying twrp for ics) and this is what it comes back with, same thing for cwm and twrp:
C:\Android\android-sdk\platform-tools>fastboot -i 0x0B05 flash recovery CWM-Touch.blob

You have to unlock to install a custom rom. Think it over and do some more reading. You could build a house since there is no shortage of bricks. :banghead:

do you think there's any chance of being able to do this without unlocking in the future?

Nope. One requires the other. Simply put - ASUS does not want to deal with true user-created bricks. That's why they make it optional.

Hi
I recently got a Asus TF300T with the latest firmware. As I wanted to "root" it I unlocked the boot loader and tried to install a recovery kernel as explained on http://forum.xda-developers.com/showthread.php?t=1668173
Everything seemed ok :
$ ./fastboot -i 0x0b05 flash recovery recovery.img
sending 'recovery' (5306 KB)...
OKAY [ 0.960s]
writing 'recovery'...
OKAY [ 6.230s]
finished. total time: 7.190s
But when I try to start the RCK, the ASUS says "Booting Recovery kernel image" but nothing more happens.
What am I doing wrong ? Is there another way to downgrade to WW_epad-user-9.4.3.30 ?
Thanks
what recovery are you trying to flash mate?

Hi !
If you have the last Asus Firmware Android 4.1.1 , you can install this recovery : TWRP 2.2.2.0 ;
- extract twrp.blob file from archive ;
- just put your device in fastboot mode and type > fastboot -i 0x0B05 flash recovery twrp.blob
:good:
If that dont work yo might need to direct the cmd programme so let us know if it works or not, but i was having similar problems and that file is w h a t i got installed
Sent from my ASUS Transformer Pad TF300T using Tapatalk 2
So I unlocked my tf300t and flashed cwm to recovery.
Everything seemed to go fine.
When I would go into cwm it was not able to mount or access any other part of my tab. I figured ok erase/format the recovery partition and try TWRP. So I booted to the bootloader, using fastboot I erased recovery but now whenever I go to flash a new recovery my bootloader either freezes or I get an Unrecoverable bootloader error 0x00000000 (not sure if thats the right amount of zeros but there are no other digits in the error code.) I can access fastboot and adb but it doesn't seem like I can flash using fastboot and I just don't feel comfortable trying with adb. Also I can access fastboot only from the bootloader screen and adb only after I boot into my current rom (stock 4.2.1)
I guess my questions are this:
How can I format my recovery or flash a new recovery?
Were the mount issues I originally encountered going to be solved with a new recovery?
Please help!
Have you tried installing stock rom (from Asus support page) using Fastboot? It should also put stock recovery in your tablet.
Not sure if it is going to work, but it's worth trying though.
1st this is not for the dev section. You should ask questions in the Q&A section.
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob
let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till its finished.
Now you should be back to full Stock with Stock recovery.

I had this problem too. But on 4.2.1 you can push file blob, and then it's can't run because stock recovery dead.
Were you able to fix the stock recovery issue?

No, I was not. I also have the unrecoverable bootloader error but I have a working device. I downloaded the latest firmware, followed the steps through fastboot and the same thing keeps happening where as soon as you try to enter a command through fastboot the green box stops flashing over rck and even though the cmd prompt window tells you something is going on nothing happens on the tablet end. It freezes. hard reboot and you end up back with a normal working device, no changes and a corrupt bootloader.

I was having this problem earlier - a new bootloader came out when they went to 4.2, but most of the instructions online don't reflect this. You need an updated recovery image, which usually has the name recovery-jb.img instead of recovery.img. When you're searching make sure the instructions mention 4.2 and jelly bean.
However, I've only managed to get one step further - have now get into clockworkmod recovery, but as with the OP I then couldn't mount anything inside CWM. I tried another instruction set which involved unzipping the ROM and using adb to push over the .blob. This hasn't worked and I have now got a pretty much bricked device - it either bootloops on the asus splash screen, or loads into CWM.
I've found that even when youre in CWM you can type "adb reboot-bootloader" into the terminal, which forces the RCK/android/wipe data page and fastbook to appear. I've also tried to download the latest stock firmware from ASUS, unzipped it to get the stock .blob out and into my fastboot directory, then run "fastboot -i 0x0B05 flash staging blob" in the terminal, as per mikaole's suggestion. This takes a while to push over the 80mb .blob, but after it says it's staged it says "done" then nothing happens and it's still bricked. hmm.
No one's figured this out? I tried flashing the blob file and my system won't boot at all
My solution
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob

Did your tablet seem to freeze after flashing via fastboot? When I push blob, the console shows that it wrote, but then fastboot on the tablet freezes & I have to manually reboot, putting me right back to the drawing board.

nope. do you use the original cable on usb 2.0 and connected to your pc not a usb hub? should work. if not try a diffrent pc - sometimes usb chipsets make problems.

I get invalid argument to all of the erase attempts and the minute I try to push the blob the flashing green icon in fastboot mode on the tablet stops. The command windows says the flash went fine but the tablet is unresponsive and must be reset. Infact any fastboot command that pushed something to the tablet causes it to look up ( indicated by the green flashing RCK icon freezing on whatever phase of green it had at the time)

I have an Asus TF300T paperweight!
I started out to root my tablet and load CWM. I unlocked it, install TWRP v2.2.2.2 as I read in a blog with instructions on how to root this tablet. I loaded a CWM ROM, can't remember not which. It didn't load correctly, and kept rebooting. I got into the screen that gives the following four options:
1. RCK
2. Android icon
3. USB icon
4. Wipe data icon
Of course, thinking I would start over and try again, selected Wipe Data. Stupid, I know.
Now, my tablet only boots into TWRP. It won't mount anything; of course, since I Wiped Data, there is nothing to mount. I have tried and searched, to no avail. I can see the tablet in Device Manager, and managed to load the Naked Universal Drivers. Now it shows up in Device Manager as Asus Eee Pad Slider ADB Interface. I can issue the command - adb reboot - and it will reboot, but I can't get it to do anything else meaningful with my meager experience.
Any help would be greatly appreciated. I would like to get this working and give it to my son, as I have already purchased a replacement for myself.
Thank you.

Hi Guys,
Yesterday I installed the new TWRP 2.7.1.0. and that is when the problems started. Everytime when i loaded TWRP my screen got messed up and i got a split screen (At that time my ROM worked). So I tried to get back to a older TWRP, after a couple of tries i finally installed 2.4.4.0. But then I couldn't acces my internal memory nor my sdcard through TWRP(The ROM still worked fine). So i tried CWM, other TWRP's, still the same issue. To keep the story short, I eventually pressed on the WIPE button in Recovery ... And now I am stuck in TWRP. I can't load any zip files.. Is there any hope?
Tab: TF300T
A small update. After some trial and error i got my rom running again and i can also get in to recovery (Power button + volume down). Now I have erased the old TWRP with "fastboot erase recovery". But now I can't install a new recovery? I tried flashing a recovery and I am getting the messages "sending recovery ok", "writin recovery ok". But i don't see the loading bar on the tab...
I feel lonely here hehe.:laugh:
