are there anyway to fix it？
thanks verymuch
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.

Hi!
I hope you can help me.
I obviously did something wrong.
Well I did unlock my tablet and got twrp running, also installed the rom but next after the reboot it just doesn't work and i will get this message (see the picture)
After that i am sent back to the interface of twrp.
I just recogniced I have twrp v.2.6.1.0 running - is that the problem?
Hopefully somebody can help me!

YOU MUST BE ON THE ASUS STOCK JB 4.2.1 BOOTLOADER VERSION 10.6.1.14.x AND TWRP 2.6.3.2+ OR CWM 6.0.4.6+ BEFORE FLASHING THIS ROM.
This is copied directly from the Developers ROM.

You didn't use 'Wipe Data' from the bootloader, did you?
Read the OP for CROMBI-KK, compare it to what you did.
Describe in detail what that was.
"Does not work" is not very helpful...
Check if you can get into fastboot.

Well,
I can go to Twrp recovery and fastboot
I did install the rom with everything present I think.. had to select some things and finish the installing
after that I had to reboot and now i just get the image with the penguins.
Can I somehow go back to the original rom? to restart these things?

If you made a nandroid before flashing this, then yes, you should be able to restore it.
But let's take it from the beginning. Post your bootloader, recovery and rom versions.
As long as you have access to fastboot you can fix this, so don't do anything hasty.
And please be as specific as you can about what you did. We can only help you if we find out where you went wrong.

hm ok I will try
well, I didn't make a nandroid backup - my fault :<
are there specific bootloader? I was on JB 4.2.1
I am now on twrp v2.6.3.2 but I was while I did the flashing on twrp v2.6.1
hm I did flash crombi-kk rom from the OP
maybe I did some wipe before in twrp .. i think it was recommended?
so now I can't do any reflash or anything in twrp - everytime I want to do something there is this error:
E: Unable to open '/cache/recovery/.version'
I also can't get access to my external SD
Check if you can get into fastbot.
Long press Power and Volume Down until you see tiny script.

All right, your bootloader is current.
I would recommend that you flash TWRP 2.7 in fastboot, then boot into it, do a Factory Wipe in TWRP (that can take upwards of 60 minutes) and flash the rom again.
Ok.. I tried but I got the answer
failed (data transfer failure (too many links))
hm I think I've got no connection, right?
well and now I get the message:
FAILED ( command write failed( invalid argument))

Alright, everything good so far.
Now download the TWRP 2.7 blob for the tf700 and put it into the same folder as your fastboot.exe.
Then issue this command:
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
if that is successful
Code:
fastboot reboot
Then boot into TWRP via the fastboot menu.
Then you can factory wipe and flash the rom

If you want to try that, go to the Wipe menu in TWRP, then to Advanced and choose "format data".
In TWRP this can take 90 minutes! D not interrupt it and make sure the tablet is charged or connected to power.
But this will erase your entire data.
The recovery has it's own partition which you can erase in fastboot:
Code:
fastboot erase recovery
.
Then flash the new recovery. You could also try TWRP 2.6.3.2 if 2.7 doesn't work.

Your posted image indicates that simulation mode is active in TWRP - turn if off in TWRP settings.
To format data, it's approximately this: Wipe -> Advanced -> Format -> Data -> confirm
Note that it takes up to 2 hours to format and trim the eMMC.

Well I don't know how but it suddenly worked.. i could reinstall the rom but now it seems i am stuck in a bootloop between the picture of the four penguins and a bootscreen of crombi-kk with loading tiles under it
between these two the tablet is rebooting itself constantly
Go back to recovery and do a wipe only Calvin cache and Cache.

Greetings -
I have an unlocked TF700 (twrp v 2.5.0.0) and I was running cromi-x. it began to crash a lot so i tried to flash a new rom and i must've done something wrong because now the tablet will not boot up. I can get into twrp and perform the options listed (install, backup, restore, wipe, mount, settings, advanced, reboot) but nothing seems to help. I haven't played with this in probably 6 months so i'm not sure where to start. Navigating these forums is like reading latin to me. I'm sure there is an explanation for this but I can't find it. Can some one link me to an existing thread if this has been discusses previously or help me out? I can't seem to get anything working on this and it's driving me crazy. I know I need to provide extra information to help identify this issue but i'm not sure what that info that is. Any help would be appreciated!
Also, I've tried a factory reset from twrp as well and it gives me the following messages
E:unable to mount '/external_sdcard
Updating partition details...
E:Mount: Unable to find partition, for path '/'
When I reboot following this, it takes me directly to TWRP.
I'm guessing my tablet can't find my SD card? Maybe that's an easy fix?
Thanks everyone for looking at this and thanks for anyone that takes some time to educate me.
Most if all: Do not do anything desperate anymore. Your tablet is savable at this point but close to being bricked! Wait for help, I have to go to work now, but will be back tonight.
In the meantime write up a list of things you did as good as you can remember, find your bootloader version and post that.

Thank you for the reply. My bootloader is "<1.00 e> released by 10.6.1.14.8-20130514"
It also says "key driver not found" immediately before the bootloader data upon turn on
Ok, good start. Now - what's you situation exactly? Can you boot into the bootloader or is recovery the only thing accessible right now?

I can enter the bootloader (hold power on and volume down correct?) and it displays RCK, android and wipe data options. It only takes me to recovery tho.

Please try to be very specific. When you enter the bootloader, does it stay there or does it automatically, without your interaction, boot into TWRP?
Did you use the Wipe Data option from the bootloader or do a Factory Reset from the Settings menu?
Do you have fastboot setup on your PC?
If not, find the instructions to setup fastboot here: http://forum.xda-developers.com/showthread.php?t=2688891

When i enter the bootloader, it stays on the screen. If i reboot without entering the bootloader, it goes directly into TWRP. I am not sure if i used the wipe data option or the factory reset (it has been probably 6 months). I will install fastboot on my PC now.
Interesting.
I assume you do not have any data on the tablet you need to preserve, right?
Once you got fastboot setup and "fastboot devices" returns the serial number we'll clear your misc partition (just in case) and fastboot erase your data partition. I think after that you should be able to boot the rom.
Actually, remind me, what was the last thing you flashed? Did you update TWRP already or are you still on 2.5.0?

Correct, i don't need any data on this tablet; i can wipe it clean. I think the last thing i flashed was Cromi-X (not sure the number; was back in August probably. My TWRP is 2.5.0.0; i haven't updated that one. I will try to do the fast stuff tomorrow morning; too late tonight. Thanks for all your help.
Cool. I need to sleep too
Yeah we're going to have to update your TWRP version. 2.5.0 is too old to flash anything recent. And while we're at it we'll update your bootloader too. All in good time. See ya tomorrow

Ok, here's my thinking:
I don't know why the tablet reboots to recovery if you try to boot Android - never seen that before.
That it refuses to boot the rom - seen that plenty
That it only boots to recovery and not even to the bootloader - seen that quite a few times if the user used Wipe Data or factory reset from settings.
You seem to a have a mix of both which makes it unique.
So my advice is:
to clear the misc partition (where a "format data" request may still be lurking) in fastboot
wipe the data partition in fastboot - just general housekeeping
flash a new bootloader and recovery using your current recovery
Use the new recovery to flash the rom of your choice - which one do you have in mind?
So let's start. First make sure you have a fastboot connection:
Code:
fastboot devices
Then erase misc and user data
Code:
fastboot erase misc
fastboot erase userdata
You are still in the bootloader menu, push the Vol Up button on the flashing RCK to enter recovery
Flash the 10.6.1.14.10 bootloader, packaged with TWRP 2.8.4.0 from this post (2nd zip from the bottom)
http://forum.xda-developers.com/showpost.php?p=55238386&postcount=3
You have to reboot after this step for the bootloader and recovery to install.
You'll see a brief blue progress bar, then the tablet will reboot again. At this point hold Vol Down to enter the bootloader and then enter recovery which should be 2.8.4.0 at this point.
Flash the rom
Good luck!

I have successfully completed the steps preceeding the above suggestions; I am not sure how to flash the bootloader. I am trying to follow the guide posted here (http://forum.xda-developers.com/showthread.php?t=2688891) by using the command code
fastboot -i 0x0B05 flash recovery twrp.blob
however, i cannot rename my blob file (contained in the 10.6.1.14.10 bootloader "second zip from the bottom" that you linked me to) to twrp.blob. it is simply called blob. am I doing this wrong? i tried using the above command with just blob and it didn't do anything.
on another thread (http://forum.xda-developers.com/showthread.php?t=2688891) you recommend visiting (http://techerrata.com/browse/twrp2/tf700t) and downloading the latest version of twrp. Should I download this file (openrecovery-twrp-2.8.5.0-tf700t.blob) and rename this to twrp.blob?
Also I am not sure on a new custom rom; i've been out of the game for a while; any suggestions?
No the zip is a flashable package. You install just like a rom zip:
Choose Install in TWRP, navigate to the zip, check the box for signature verification and swipe the button.
This will write the bootloader and recovery to the staging partition. When you reboot the bootloader writes them to their proper partitions, then it reboots the tablet again. That's when you can "catch" the boot process to go straight back into recovery and flash the rom.
Maybe you want to try CROMI-X first. Still a very good rom and very stable. Or check the dev section, many to choose from...

Hallo there,
at first sorry for the nearly 10th post about this topic, but as you can see I'm in a different position than the most of you. I'm on Arch Linux here and I don't rly want to root my phone with a windows box.
I got adb and fastboot installed, but I can't find a general guide how to flash recovery and root with them, because there are always these click-click-shiny-shiny gui .exes for windows, which take some tasks.
I did root my Droid 3, but this was years ago, and I did never get into this stuff so deep it would help me now. I am a lil exhausted from the day, and don't rly want to puzzle my way through the google search results, which as described above lead to a .exe with a gui at some point.
Anyone here, who knows the basics and is willing to give me a hand here?
As I said I'm a Linux aka a terminal user so you don't need to be soft on this, I just need it compact but complete.
Thanks in advance
p.s. What I think will be relevant at some point, based on the search results so far:

This is the tldr:
I have rooted my Mate 7 now like this:
1. got my unlockcode here
2. installed the recovery
Code:
adb reboot bootloader
fastboot oem unlock (insert code)
fastboot flash recovery twrp_3.0.2_mate7_6.0.img
fastboot reboot
3. moved supersu to my sd card
4. booted into recovery (by shutdown and power on with power+volUP+volDOWN pressed)
5. backup system (just for safety)
6. install -> chose supersu.zip
DONE
EDIT: HOW DO I MARK THIS AS SOLVED?

Yay well done and also on posting the solution. I reread what I typed and couldn't make sense to why I mentioned cwm and twrp (same stuff, diff developers or so) so maybe I mixed up bits of another topic
Hi all,
I'm a total noob here. Somehow I managed to unlock and root my ASUS TF300T successfully, even though the instructions I was referring to were sketchy. Unfortunately I started the process before finding the detailed instructions here on how to flash the ROM. So it looks like I misinterpreted the sketchy instructions and hosed up the process. I managed to get the Katkiss zip file on the internal SD of the tablet, but when I tried to install it, it failed.
I now know where I went wrong so I'm not sure if it's fixable now: Rather than wipe while in TWRP, I wiped from the main bootloader screen (RCK, Android, WIPE DATA). Idiotic noob mistake which I realize now, but too late.
Currently when I attempt to boot up using the power + down volume, my screen shows:
Code:
Key driver not found.. booting OS
Android cardhu-user bootloader <1.00 e> released by "US-epad-10.6.1.27.5-20130902" A03
If I select RCK, I can get to TWRP, but it can't find a way to push the stock ROM file from ASUS from my PC back to the tablet. I tried using ADB push, but I get an error that it's not a valid command.
I can see the tablet in Device manager if I connect using the USB, but when I use the ADB devices command, nothing is returned - no error message, no device information.
Any thoughts on how whether it's possible to get back to the stock ROM? It shows
Code:
The Device is Unlocked.
on the ASUS splash screen but always boots to TWRP if I do not hold the down-volume button when starting up. I'm not sure if it's still rooted.
Thanks in advance for any suggestions!
I would like to advise you to get back on stock rom without any further experiments.
First of all the USB driver must be installed on your PC.
-Download “Minimal ADB and Fastboot”.
-Make a folder C:/Fastboot and extract it there and install it. Download the latest firmware V10.6.1.27.5 fitting to your device from the ASUS official website and unzip it twice.
-Copy the .blob file into the folder C:/Fastboot.
-Start “Minimal ADB and Fastboot” and put in "fastboot devices". The device should appear as "xxx device".
Now type in step by step (wait after every step!):
fastboot erase system
fastboot erase recovery
Fastboot erase user data
fastboot erase boot
fastboot erase misc
fastboot erase cache.
After that put in "fastboot -i 0x0B05 flash system blob" without " " .
Now it takes a while "sending..." appears then "write..." and the load status will be shown.
If loading is finished put in "fastboot -i 0x0B05 reboot". It takes a while to start into a clean JB 4.2.2!
After that you are ready to flash Kang TWRP 2.8.7.2 again and make a clean install of a custom rom of your choice by taking care exactly of the instruction given by Timduru in each post #1 of each CR.
Thank you for your reply, ebonit. It looks like I have an older version of TWRP currently installed: v2.5.0.0. Is that a problem? If I'm going to flash TWRP again, should I definitely overwrite the current install with Kang TWRP 2.8.7.2?
Thanks again. I may have additional questions because I'm totally new to this and there's so much information out there. I appreciate your patience!

For all MM 6.0.1 and N 7.1.0 versions you need Kang TWRP 2.8.7.2. That's mandatory as seen in each post #1.
If you get back on stock rom, you don't have any custom recovery remaining. There is nothing to overwrite. You must flash Kang TWRP anyway. After that you may flash any custom rom of your choice as clean install.
Thank you so much for your help. It looks like I'm back to the stock ROM. I will try flashing Katkiss later when I can give it my full attention and am less likely to make stupid errors!

I cannot stress this enough. MAKE AN NVFLASH BACKUP ASAP!!!! I bricked my device 2-3 years ago and had I made an NVFlash backup I could have recovered it. Unfortunately I did not have a backup and so I just had the tablet sit on my shelf until a few days ago when I finally got a replacement motherboard and swapped the bricked one out. Again MAKE AN NVFLASH BACKUP. You can use the flatline utility described in one of the threads in this device's forum here on XDA.

Ebonit, this is what I need to know, all underlined.
Can anyone give me complete step by step instructions on how to install MM 6.01 on my TF300t. It's so slow it's annoying and unusable. I am a newbie and don't understand how to flash this and flash that and do several other steps... more detailed instructions for each step below would be so helpful. I would be more than happy to make a payment donation for more detailed help.. thanks! Cindy

The first time or everytime you have an issue when dirty flashing (Especially when changing android versions):
do a full wipe , if you have issues make sure that you format /data (format is different than wipe)
Warning: formatting will remove what is stored in your internal storage, so store the rom /gapps/supersu zips onto an external storage (microSD, SD card..) or make sure you know how to push them back through adb.
Change /data filesystem to f2fs
Then everytime (even when "dirty flashing") do the following steps:
Flash the rom
Flash the SuperSU zip
Flash gapps
Wipe cache/dalvik
Reboot
What do you want? Every information you need is written in your post. Any further questions you may have will be find an answer somewhere in the forum.
Kang TWRP is the most important tool. It will do the job. Do you have it?
If not, look here http://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479. There is the install instruction as well.
If yes, then start into recovery and and realize step by step what you found in post #1 and is written down by yourself in your post itself.
