Rooting TF300T - Transformer TF300T Q&A, Help & Troubleshooting

Hello, guys. I've tried rooting my new tf300t tablet (10.4.2.20) but I've had no luck. I've gone through the youtube videos, but they all state different firmware versions. The furthest I've gotten is getting the fastboot screen (my device starts up saying "the device is unlocked" but I can't install CWM or TWRP. I've done the computer method "cdm>fastboot -i", and have gotten into bootloader and pressed RCK, but the custom recovery won't boot. Thank you.

The problem is getting root.

If you have managed to unlock the bootloader you should be capable of performing a
Code:
fastboot -i 0x0b05 flash recovery twrp.blob
but before that perform a
Code:
fastboot devices
to see if you even haves access to the fastboot properties....you do this of course when you are in fast boot itself....and the latest TWRP can be downloaded from here or here. Make sure extract it to the blob extension before flashing.
And as always you take the risk of bricking your system! Once you get recovery to load rooting will be a piece of cake.....you can go here to get more info.....GoodLuck

I did rename the file to .blob, but the problem is getting it to TWRP to boot. I've tried flashing TWRP via the cmd -i method on the CPU, but I can't get it to boot when I press volume down+power. It displayed the bluebar on the TF300t as if indicating that it finished installing. then I went to command & it says:finished 7.730s, but It stays stuck on "booting Recovery kernel image". Thank you!

Dont know if this helps, but I just bought/unlocked/recovered/rooted my TF300T yesterday and had a similar issue.
Heres what I did.
1) I got it unlocked via Asus unlocker utility (after registering with Asus, it unlocked without issue)
2) Made sure I loaded all my drivers correctly
3) Used (ADB reboot bootloader) to get to bootloader screen but wasnt properly going to the (USB ICON) via the down button.
I kept hitting the volume up and engaging the (RCK ICON) instead and it wouldnt boot to recovery and just gave
me the upside android with error
4) I realized that screw up and got to the (USB ICON) and it went into fastboot screen (says it at top lines of screen)
5) Now I pushed CWM via cmd line(-i xxxx) to it - but when I rebooted and tried to go to recovery it wouldnt start, so I
pushed CWM again using the cmd line (-i xxxxx). It worked the second time.
Now it rebooted fine and I went back into recovery and flashed the root-signed zip (I used a wrong file), but after rebooting I didnt have root. Recovery two more times and it still wouldnt give me root. Found another copy of Superuser3.2 and flashed that and it worked.
I like TWRP more, so I went to their site, downloaded the newest version, and went to recovery, used the cmd (-i xxxx) and
flashed the newest blob file from them.
Now it works fine.
I do not know if this helps, but my main hangup was not using vol-down to get to the USB ICON instead of the RCK ICON.
Here is the link I used. http://forum.xda-developers.com/showthread.php?t=1845377
Good luck
P.S. rereading your post, especially the end, it just sitting at "booting recovery image". Mine did the same thing because I did not correctly
install CWM.

Bricked (?) ASUS Transformer Infinity TF700T

Hi there,
I need your help urgently.
I received a brand new TF700T and did make it work to support root.
I also did unlock the bootrom protection.
When I tried to install a custom ROM manager (Clockwork Mod) image from:here
The device didn't want to start any more - showing message:
The Device ist Unlocked.
Android cardhu-user bootloader <2.10 e> released by "TW_epad-9.4.5.22-20120615" A03
Checking for android ota recovery
Booting recovery kernel image
But nothing happens anymore (
I can wait for the battery to run empty in this mode.
There' no chance to boot from Micro SD.
The only thing what works at the moment is to connect the device via APX drivers.
I tried to communicate with device via NVFLASH tool
But when trying this - I get the message:
Nvflash started
Unknown Device found
Does any one have an idea where to find appropriate drivers for Nvflash?
Or the parameters to match TF700T?
Thanks in advance!
if you are able to access APX then you still have hope, first of all you need to push custom recovery like TWRP via fastboot mode and then install custom ROM. Most likelly you were to lazy to read a lot information on this forum how to install stuff properlly.
EDIT: if Tf700t has pin hole you should turn it off despite waiting for it to discharge...

I did already read a lot - for hours and nights.
But my main problem is: UNKNOWN DEVICE
What does TWRP mean? How do I get fastboot to work?
I'm even not allowed to enter recovery mode.
The device is just recognized as an APX -device...
I can't push or download any custom ROM since I can't communicate with the device in both directions...
For those who messed up really bad and can't boot but are unlocked.
EDIT: I didn't see that you are not unlocked. then you should Power on + volume down, wait, see two icons select wipe, pray to god it helped or not. And if it doesn't boot and you are not unlocked last thing to do is RMA.
You are not allowed to enter recovery because you have stock one with droid dead and red triangle I guess.This is TWRP site and all instructions are here TWRP - Team Win Recovery Project is alternative to ClockworkMod Recovery but better. to get to fast boot turn on your tab holding power on + volume down and then do nothing while it asks to pres up. if you are unlocked you will see 3 icons select usb drive icon. FASTBOOT mode. now follow instructions from TWRP site. after that youl need custom rom zip. if recovery instaled successfuly and you can get into it you'll need to put custom ro into microSD or if you can into internal storage. if you can't conect to pc via cable and start cmd if Windows or terminal if Linux or mac. type
Code:
adb shell
mount /dev/block/mmcblk1p1 /data/media
you will be able to access microSD via recovery (unless it is different than Prime tf201 you will need different command, but give it a try)

Thanks for advise - BUT
I have no choice like selecting Fastboot or USB etc. with volume buttons.
These options unfortunately do not come up anymore.
My device is definetly unlocked. It shows up "Device unlocked" when trying to boot normally.
When trying to go to recovery, with Volume - hold, the device tries to launch to recovery but hangs in status:
Device is Unlocked

I have NO option to go to fastboot! Only way will be APX but nvflas always tell me unknown device.
So I was looking for any other version of nvflash.
In other forum I did find hint for nvflash ICS but didn't find right version yet.
If I only could get communication via APX worked to my device, then I could send data via nvflash and APX...
I assume you can't even go to rom as it bootloops on EEE pad screen not on rom splash screen
1. Did you try Wipe option in (power + volume down, wait 5 sec.)? [it is esential in all situations of trying to recover]
2.ammm... when you enter "adb devices" in your cmd on PC doesn't it show anything (do it while your tablet is on and hangs anywhere, just make sure it is on)? list is empty? if not it shows your device with some random letters and numbers.
Try manually setting your pc. Download android SDK and all packages for Android 4.x then in Device Manager (Control panel) find your Tablet and update your driver to Android ADB interface (you can experiment, till your device is shown correctly via adb devices command).
But first of all make sure you do or did first step. it is common issue among Prime users so maybe it can help you.

I would like to exchange email-adresses to enhance communication.
You could also send email to [email protected]
I did try with button combination (power & + button) as well, but device did not wipe.
For now - I'm about to update Android SDK )
Hopefully this works to recognize my TF700T...
If you manage to unbrick please post the information back here it may be helpful to others.

Unlock + Root was never a problem.
I managed it to unlock the device using the TF300T tool / link.
Boot loop was big problem.
I did raise RMA in the meantime. New device is on the way.
Thanks to all repliers.
I will keep off doing this again / wait until xda-experts will provide a working way to CWM TF700T.
My Transformer Infinity isn't bricked, I just can't get it to boot into recovery. (I'm unlocked and rooted, but no custom ROM.) I have tried both CWM and TWRP 2.2.0 with GooManager. The tablet just won't boot into recovery mode. I can hold the Down Volume key and Power button to have the initial boot up menu display. When I press the Up Volume button to boot into recovery mode, it just hangs like the OP talks about. I then have to hold the power button for about five or so seconds to get it to power down again. I can turn it back on and it will boot normally.
I thought maybe something was messed up because I installed busybox, or hacked the Flash Player to work in desktop mode, or tweaked the build.prop file or something. I've put the build.prop file back to default, and removed the busybox apps, but that hasn't resolved the problem. I've tried re-running the unlock tool, but it fails halfway through. I'm not sure if that's normal or not after you've run it once, or an indication of something messed up.
Any suggestions on what else to try or look at are appreciated.

Download - ADB / Terminal method:
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:

dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then reboot to complete installation.

Trying to flash the new CWM recovery, too. Mine gets stuck in the bootloader menu (where you have to choose between Wipe, fastboot mode, and cold startup). Every time I select fastboot it says "starting fastboot usb protocol" and just hangs there.

That is what it says when you are in fastboot mode, the rest of the job you do with a computer. Also we have had major issues with cwm on the Prime, I would recommend TWRP!

Manual JB update. Soft-bricked my TF300T?

Hi ppl!
First, my device failed to get the OTA Update because I deleted some system apps (see my original post).
Then I found this post where another user restored original APKs in /system/apps and managed to manually update to JB by downloading the dlpkgfile in this post.
So I proceed, restored my /system/apps (with 755 permissions), rooted with OTA RootKeeper and SuperSU, placed the dlpkgfile and command files, restarted to fastboot (Power+Vol Down) and entered Recovery mode.
The green android with the blue progress bar went for over 10 minutes, then ... the android with the RED TRIANGLE appeared
After a minute or so the device restarted, an ASUS logo with a blue progress bar ran, but then it got stuck in the ASUS logo.
I'm still able to restart to fastboot (Power+Vol Down), where a message appears:
Code:
Android cardhu-user bootloader (1.00 e) released by "US_epad-10.4.2.9-20120809" A03
, and where I have 4 choices:
1. RCK: Recovery mode, when I select this the Red Triangle appears again.
2. Android: Normal android boot, gets freeze right away
3. Fastboot USB download protocol: Tried using ADB, but don't really know what it is. Here's an image of how the device appear in my Windows PC
4. Wipe Data: Already done this, seems to wipe user data, but still gets stuck on ASUS logo
Some pictures I took of my device: http://imgur.com/I13ou http://imgur.com/Jezpn
I also tried downloading .30 firmware from ASUS website and placing the Zip contents in my SD card, then booting recovery but no luck.
It's pretty awful that everything went so bad, I'm hoping there is a solution.
Anything would be really appreciated!!!
Thanks!

OK, I found this tutorial about flashing ASUS firmware with fastboot: http://www.theandroidsoul.com/how-to-restore-asus-transformer-tf300t-back-to-stock/
The problem is that the following commands:
fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 flash system US_epad-user-9.4.3.30.zip
both produce the error: "Signature mismatch"
I guess it's becaus my fastboot is newer version, since it was actually installed during the JB update, but I'm trying to flash a older .30 firmware.
I gues I will have to wait ASUS releases the new firmware for manual flashing it.
Just guessing...

I dont see how this is solved......I have seen some people comment they have no fastboot or recovery,
I tried to do manual update in cwm and when I rebooted with adb all I have is asus boot logo, it also does not say I have an unlocked bootloader,
I have no fastboot no recovery no adb connect all I have is asus boot logo.......volume+-power does nothing vol down + power also does nothing.
how do you flash new firmware without adb or any type of recovery?

AFAIK you should still have access to fastboot, I'm newbie and never messed up by unlocking the bootloader
It worked!
Thank you so much! I had this same problem with mine and couldn't find an answer anywhere until I found your post.
hmm, I lost my tablet for nearly a month then updated CM10 when prompted having connected to my new wireless. This of course (since the Oct update) put the ROM out of kilter with the bootloader. I didn't have an old ROM on the SDCARD, and old CWM so I couldn't mount an external to get a rom on. I tried pushing a rom to the SD with adb but the drivers weren't going in right and I just couldn't get any joy. I followed this thread to fastboot the current stock JB on in the hope that it would give me a fresh start but it's hanging now at the second (glossy) ASUS logo. I really don't know where to go from here. Is it possible there was a problem with the write?
erasing the memory from the boot menu worked!

Can you tell me how you erased memory from boot menu - or maybe i understand this in different way.
I have only bootloop and it boots to CWM where i cannot mount any SD card - not internal not external.
Also Vol down + power doesnt work - there is no option to enter fastboot mode....device just bootloops and then enters CWM...
Tried to push through adb but there is no SD card to copy files. Tried different methods but cannot mount any storage...
Thanks JB update

[Q] TWRP 2.4.4.0-JB killed my Tablet?

I found multiple development threads that are close to this, but here's the deal...
I took Asus 4.2.1 OTA update and used that for a while.
The device was already unlocked and I decided to try TWRP 2.4.4.0 for recovery before trying any custom ROMs
I followed the big bold red instructions that said:
If you have taken the official Asus Jellybean OTA then be sure to install the '-JB' version of the recovery for your device - and only flash roms that are based on the Asus OTA.
I downloaded the -JB version (at that time, -ICS was the only other choice), and installed it via fastboot.
Upon rebooting, it will only boot into recovery and TWRP can't see any partitions. More importantly, I've spent almost a month now reading the threads that are related to this trying various suggestions in trying to break out of this, and during this time, I've realized that I can't flash anything. ADB works, but the devices says "123456789ABCDEF recovery". I can run "adb reboot bootloader" and I will get my 3-icon 4.2.1 bootloader screen with a blinking green square on RCK. Fastboot devices shows my S/N, and it acts like it is flashing (tried flashing the -4.2 version of TWRP 2.4.4.0 and a new copy of the JB 4.2.1 OTA ROM), but all the tablet does is lock-up. The green square stops blinking and, even though fastboot says it's working, the tablet is no longer responding and requires a reset to reboot, upon which it boots right back into TWRP.
I'm just asking if there is a way out of this yet that doesn't involve replacing the main logic board.
I suppose what bothers me more, is that Teamwin's website for TWRP still has the same instructions in big bold red letters, without acknowledging that there are TWO official Asus Jellybean OTA releases. One will work just fine with the -JB version they specify to download, the other will do what mine did. Anyone current with Asus releases is gonna follow these instructions and brick their pads unless they already know about the -4.2 version of TWRP.
Yo!
Have you tried flashing asus stock 4.2.1 system blob using adb?
Do you know what the command for that would be? I have the same problem. But I don't wanna flash it to the wrong partition.

Here is the main point.
- Method 2: Update using fastboot
Notes:
You will keep all your data
This is the best method to update your tablet if you want to keep all your data, and the safest one
Ensure you have the correct drivers for the tablet installed on your computer, or you will have a "waiting for device" error
To update using fastboot, follow this steps:
If you don't have fastboot yet, download it from here an unpack it somewhere on your computer
Extract the Asus firmware file and put the blob file inside fastboot folder
Open a command line on fastboot folder (write "cmd" on Windows search bar at the Start menu, and then
Code:
cd "FOLDER WHERE YOU EXTRACTED FASTBOOT"
, or you can just use SHIFT + RIGHT CLICK on the folder and select "Open command line window here" or something like that)
Reboot the tablet holding the volume down key until you see some icons. Use the volume down key to select the USB icon and then volume up to select it
Connect the tablet to the computer if you didn't do so
Write
Code:
fastboot -i 0x0B05 flash system blob
, hit enter and wait until it completes
Write this to reboot your tablet:
Code:
fastboot reboot
or hold the power button for 10 seconds if the code doesn't work
You are now updated to Android 4.2
There are 3 things keeping this from working:
1) fastboot -i 0x0B05 flash system blob
This locks the tablet up. Fastboot thinks it's still working, but the blinking RCK has stopped blinking and...
2) fastboot reboot
... doesn't work because the tablet has locked up from the flash attempt. You have to...
3) hold the power button for 10 seconds if the code doesn't work
Which does reboot the tablet, but it goes right back into TWRP, and you have NOT been updated to anything.
Now, in my particular case, I can get it to "adb reboot bootloader" and tell it to cold boot Linux to get into my OS, but that never happens either. It's likely been wiped from one of my multiple attempts at trying others' suggestions for getting out of this.
I'm sorry, you bricked your tablet permantly... Only Asus can fix it now... You flashed a wrong recovery for your tablet... You read the wrong post! That one is for Android 4.1 and not 4.2...

I did the same thing as the OP. I'm not new at this, I've rooted and run custom ROMs for years on dozens of devices. I always do lots of research before starting the process. What the OP and I are saying is that the Team Win site doesn't state anything about the 421 patch and if you look at the file list, the patch only exists in the 2.4.4.0 version. With those two things in mind, a reasonable person would conclude that 2.5.5.0 is patched for both...as long as you use the -JB version. Obviously wrong as I now know, but certainly not clearly wrong before bricking the device.
I would never assume to blame the Dev's, but I (we) are asking that they be a bit more blatant with the fact JB v4.2 MUST USE TWRP version 2.4.4.0-4.2 and not anything else.
Now, for good or bad, so many people have now bricked their TF300's that there are many threads like this one. Any research at this point will reveal this issue. Still, Team Win should post the warning.

I wish it was as simple as reading the wrong post... When I downloaded TWRP 2.4.4.0, there were only -ICS and -JB files listed (much like TWRP 2.5.0.0 is now)... Wouldn't you have picked -JB?
Even now, Teamwin's directions tell you that, if you took the Asus JB OTA, that you need the -JB version. They don't differentiate WHICH JB OTA, and they don't mention that a -4.2 version specifically for the 4.2.1 OTA exists. Never mind mentioning that using the -JB version on the latest Asus JB OTA update will BRICK THE TABLET.
There are 192 people that have downloaded the 2.5.0.0-JB blob file as of now. How many of these folks do you suppose have taken the Asus 4.2.1 OTA update and are about to permabrick their tablets?
It sickens me to know of the 192, likely most are on 4.2.1. I only hope they catch it before pushing the ROM.
When you flash recovery its flash ix505blah recovery recovery.blob is it flash ix5o5blah system system.blob? If that makes sense? Or no.?

The two things here centers around the fact that TWRP is the only thing that will boot, other than the bootloader (but you have to boot TWRP first).
1) If you are in TWRP, there are no partitions mounted. In fact, there are no mmcblk devices at all, which is why there are no partitions mounted. As a result, there is nothing to flash to from here (even if fastboot worked). Adb works from here, but the device serial says "123456789ABCDEF recovery". Fastboot detects no devices at all from here.
2) If you reboot bootloader from adb, you can get access to fastboot. However, any flashing from here locks up the tablet, even though the command looks like it's running and completing the first time. Adb does NOT work from here, sees no devices. Fastboot looks like it sees the right device until you try to flash something with it. Once you try to flash anything, no fastboot command completes, furthering the notion that the tablet is frozen. A reset reboots the tablet back into TWRP, and nothing has changed. Repeat the cycle ad nauseum.
Basically, you can't do squat from TWRP, and fastboot flash from the bootloader locks up the tablet so you can't flash anything. I'm pretty sure it will take a logic board replacement to fix it at this point unless someone comes up with something better.
I'm having the exact same issue as you... I had flashed the TWRP JB blob and it couldn't recognize anything so I tried to flash CWM. Now...My fastboot doesn't do a thing since the blue progress bar doesn't show up and just freezes when trying to flash the stock firmware. I don't think I can send it to Asus for warranty either since my device is unlocked.
Well, I figured there's nothing to lose, so "fastboot erase recovery" got rid of TWRP. So now, it just hangs at the Asus logo unless you hold Vol- while booting, then you get the standard 3-icon bootlader.
I still can't flash anything with fastboot without it locking up though. Not sure I got anywhere... lol.

You can't flash a recovery? And what about the stock Rom?

Lol did that too...I don't know if there is anything left to try. Did you try putting stock rom on an external SD card and running RCK?
Ok...so now that I won one, there is a guy on e-bay that has a bunch of TF300T-b1-bl 32gb Transformers with broken screens. He is posting pictures and they all appear (based on the picture) that they have operable firmware. Mine will be here late in the week...I'll pull the main board and put it in mine. I'll let you know how it goes.

I did the same thing and got the same result. This i very interesting because the
Code:
fastboot -i 0x0b05 flash <partition> <filename>
command which tries to write/edit something on the partition fails (maybe is due to some encryption introduced in 421) but the
Code:
fastboot -i 0x0b05 erase <partition>
which also does the write/edit, succeeds. What I'm trying to say is that either both should fail or succeed because both are trying to do some editing to the storage.

Yeah, if it's the ones I've seen the hard part there is that they go for more than a replacement logic board does. Sure, there's likely some other parts still good in there, but if it just has a bad digi, I'm too apt to fix the digi... Basically, I need one where both the digi and the LCD are shot, and goes for less than the logic board does.
Joel, yeah, we can't flash anything. Fastboot flash <any partition> <any file> locks the tablet up. As Vahid alludes to, this is very odd because we have no trouble with fastboot erase. Having a stock image on an SD card and trying to get RCK to reload it doesn't work, presumably because it can't mount the external SD card.

Just got my TF300 back for Asus service center. They said that they had to replace the motherboard @ a cost of $186.00 total, parts and labor. Told them to just send it back. I'll buy a Nexus 7 instead for the same price almost.
Got my broken TF300 ebay win today. Digitizer and LCD were toast. But, the main board went right in to my bricked TF300. I'm unlocked, rooted, and running 4.1.1 and life is good!

[Q] Asus TF700T cannot flash CWM with Fastboot (commands successful nothing happens)

Hi,
Think I've been all over google and the xda forums now but haven't found any solution to this.
I'm trying to flash CWM and root my TF700T with JB 4.2.1, following XDA's guides: http://forum.xda-developers.com/showthread.php?t=1916762
The big problem is: When I boot into Fastboot mode and connects my device to my PC, I CAN see my device using the "fastboot devices" command - and I CAN issue the right commands to flash, and they are successful - but nothing happens on the device (only shows "Starting Fastboot USB download protocol"), not even after issuing the reboot command. If I reboot manually and choose RCK I only get the dead android. Nothing's wrong with the Android installation - it works fine.
Tried the following, all giving me the same result:
- Tried the whole procedure on 3 different PC's, 2 with Win 7 Ent 64 bit, one with 32 bit
- Tried every USB port directly connected to the motherboard, and only using one directly connected USB cable
- I've tried the naked drivers (http://forum.xda-developers.com/showthread.php?t=1766220)
- Uninstalled drivers, rebooted and reinstalled drivers both automatically and manually a thousand times
- I've installed Android SDK Developer Tools
- The CWM image is unzipped in the same folder as Fastboot
- Device is unlocked successfully with the Asus Unlock tool (shows "device is unlocked" during boot)
- I'm in "developer mode" by pressing "Build number" several times in Android
I noticed I don't get any popup that let's me choose USB mode during startup - it just boots right up and shows:
"Starting Fastboot USB download protocol" + the RCK, Android and Wipe Data buttons. (but I understood that should be correct?)
Any clues will be highly appreciated.

Have you tried motochopper to root. Twrp recovery is recommended for the tf700t running 4.2.1 and If you can get root you can then download twrp recovery via Goomanager app.

Haven't really tried that yet, but thanks. My OCD is telling me to install CWM - I can't really see why it's not working - no one seems to have this issue other than me. Really annoying! Absolutely no response in fastboot at all, and I always get "successful" messages on the PC. As soon as I press enter in CMD, I see the screen just sort of freezes up (the RCK icon stops blinking)..
EDIT: I can run these commands:
"fastboot devices" (my device shows up)
"fastboot -i 0x0B05 reboot" (my device reboots)
But when I run "fastboot -i 0x0B05 flash recovery recovery.img" the device seems to freeze.

I would just do what the previous poster said. Rooted, then install TWRP via GooManager. Easiest way to do it now . Plus as said before TWRP is recommended for the TF700.

Also once you are rooted and you have twrp revovery installed you could then use your recovery to install cwm I think there is a flashable zip version.

Yes, CM10.1 should work on the new boot loader, but it would not work with a patched version of TWRP 2.4.4 but if you got TWRP 2.5 then it dont matter. Once TWRP is install I would download titanium and back up all apps and data. To go from stock to CM you must perform a full wipe.

OK goodluck.
Allright, a bit late, but I just installed TWRP by clicking "Install OpenRecoveryScript" from the GooManager menu. I have to manually boot into TWRP by pressing power and volume down, but it works perfectly. I find that TWRP is a really great alternative to CWM.
Seems it was nothing wrong with my TF700T after all, it just didn't like CWM in my case.

Fastboot CWM/ Root Help needed

I have been trying to put cwm on the tf300t for about two days now reading everything and still got no where. The device is unlocked i used asus apk to unlock it. every time i do the power and down step i do not have the usb option just rck, cold start, wipe data. i cant do anything with fast boot to put cwm onto the tablet. any help would be appreciated. i tried reinstalling fast boot and reseting the tablet. i am on 4.2.1
Which guide are you using? The 4.2 bootloader automatically connects in fastboot mode as far as I know when you get into the bootloader menu which is why the USB icon isn't there. You should be able to use fastboot commands whilst in the bootloader menu

I did read that somewhere and i tried running the recovery through fastboot but it just says waiting and does nothing. I also noticed when i plug it into the computer it says fastboot on the usb but it has a little symbol next to it as if it wasnt running right,but i have reinstalled it a few times
AFAIK, there is no version of CWM compatible with the 4.2 bootloader. You'll need to use the TWRP versions that end with -42.
I have tried installing TWRP running command "fastboot -i 0x0B05 flash recovery twrp.blob" still no luck just says waiting for device and the tablet stays at the rck screen
