I've been trying to get nvflash access though this guide [androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/] but after doing "Step 1: Flash AndroidRoot BL" and rebooting the device it gets stuck at the ASUS logo screen (without the spinning wheel).
It's an unlocked TF700T successfully downgraded from JB to Firmware .30.
Did anyone else encounter this problem and has a solution?
I'm a little afraid to do the whole flashing proceedure through fastboot again without knowing if that's a good idea.
Why did you downgrade to an ICS firmware???
Which guide did you follow? Step 1 should have been to flash the recovery flatline_device image. And then you use it to flash the modded bootloader (which is JB 10.6.14.4 BL btw).
Can you still boot into fastboot and the recovery?
Here are the official instructions for nvflash: https://www.androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/

Thanks for the quick reply.
I downgraded because a guide told me (here on XDA) that to root my device i'd have to downgrade to ICS because of some exploit, which has been apperantly closed in JB, for 'motochopper'. Well that's what I remember.
My Firefox and PC crashed and I lost my tabs so I couldn't find that guide right now...
For nvflash I read exacly that guide you refered to.
I am still able to get to the flashed flatline recovery and since the usb icon (fastboot) isn't there where the 3 icons are showing I assume it's running by default (?).

Yes you are on fastboot by default now.
So, what could you suggest?
Should I (be able to) upgrade back to JB, to 10.6.14.4?
There's no need for root in any of this. Downgrading was what messed you up I believe.
I think you are ok. That you have only 3 icons indicates that the bootloader flash went fine (ICS BLs have 4). Confirm this by reading the tiny script in the upper left on the bootloader menu screen.
My guess is that this bootloader doesn't do well with ICS firmware. But the BL flash happens before Android gets booted. Did you see a blue progress bar during reboot? That would have been the bootloader installing. So it flashed ok, but then got stuck on booting the rom.
So you should be ok to proceed.
The rest of the process is done in recovery and APX mode. Shouldn't matter what ROM you have installed.
Once you generated your backups, you have to flash a bootloader and recovery for whatever rom you want to run.
I would recommend you flash the bootloader/TWRP package from the CROMi-X thread. That BL may boot the ICS rom you have currently installed, but even if it get's stuck on booting the rom - don't worry.
Same process: bootloader and recovery get installed before Android boots.
Just boot back into TWRP and flash CROMi-X. Even if you eventually want to run something else - this would give you a stable base.

jhh
yeah after flashing the AndroidRoot recovery image (flatline_tf700.img) thorugh fastboot I saw the blue bar telling me it flashed successfully. I could even reboot .
But then after flashing the AndroidRoot custom bootloader I wasn't able to reboot anymore. There was no blue bar during reboot.
The upper left corner says:
Code:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.14.4-20130329" A03
Starting Fastboot USB download protocol
Hm... I was planning on having CROMBi-kk but the guide says it needs 'ASUS STOCK JB 4.2.1 BOOTLOADER VERSION 10.6.1.14.x'... so that looks like that won't happen for me unless I manage to flash it back to the stock bootloader somehow. :/
So do I understand this correctly:
With the current Firmware .30 still installed I should take the latest CROMi-X package. Flash the recovery and the bootloader over the current one and then flash the CROMi-X rom?
What about nvflash then? Will I be able to generate the blob files with TWRP? I'm asking because AndroidBoot recovery looks like a modded CW-recovery I think and it has the options 'advances > wheelie > ...' , where you do the whole "nvflash stuff".

Can you get to the recovery now? Maybe you can just continue with generating the blobs.

Yes, I was able to create the wheelie blobs if that's what you mean, but I wasn't able to adb pull those. Don't know what I'm doing wrong there.
I'm not sure how to continue from here on after creating the blobs.

I wasn't able to adb pull them either, but they are there. Serach your entire SD card for blob.bin and/or bricksafe.img and you'll find them. Can't remember where wheelie hid them.....
You have a very specialized recovery and bootloader right now which you have to change to run a rom.
To get to the latest bootloader you can either flash the bootloader/TWRP package from the CROMi-X thread or flash the latest Asus firmware file.
Then reboot.
If you want to go for CROMBi-KK you have to install TWRP 2.7
Reboot
Do a factory wipe in TWRP
Then flash CROMBi-KK
Ok got it all sorted out with alot of help.
There was alot of fastboot erasing and so on involved
and flashing of the latest Asus firmware.
Then we got the whole nvflash procedure up and running, generated and saved the blob files,
flashed TWRP and CROMBi-kk and voila.
My TF700T is up and running.
thnx for all the help

It's faster than stock asus rom that's for sure.
I know it's not quite finished but I've noticed some bugs like:
- when using chromecast the right quicksettings panel glitches quite alot (I'm using trebuchet)
- I've noticed that occassionally the power button (on device and keyboard) doesn't work to turn off the tablet or set it to sleep. only by closing the 'netbook/tablet-keyboard-hybrid-thing' it goes to sleep. after soft-resetting it the problem was gone. I think it only happened when I accessed the glitchy quicksettings panel while using chromecast.
Other than some of the still missing features it's running quite good
I don't regret flashing this custom rom over the slow and old stock one.

When I hold the power button plus Volume down key I am only getting two options. One is to wipe data and the other is to enter USB Fastboot mode. I just upgraded to the latest TWRP recovery and when I click the Wipe icon the TWRP splash screen shows up for a second. What I am hoping is that someone has some insight as to why the recovery icon has disappeared and how to get it back. Usually I am not the person asking the questions generally I am the one answering. If anyone has a clue it would definitively help. I did search and found a couple threads where something similar happened but there was no direct answer as how to fix it. Please help.

I had a similar issue when I restored a TWRP backup I made with pre version 2.2.1. I was able to get help from the Dees_Troy on IRC.
Notes from IRC conversation
Whatever you restored from your pre TWRP 2.2.1 old backup is not a kernel. The dev that made the original device configuration files for the 300 couldn't find boot . So he just threw boot onto the wrong partition you need to install a working kernel via fastboot.
Steps that got me backup and running.
1. Flashed latest TWRP via fastboot. 'fastboot -i 0x0B05 flash recovery twrp.blob' rebooted
2. Downloaded a cm9 rom and opened the zip file and extract boot.blob . Flashed with 'fastboot -i 0x0B05 flash boot boot.blob' then rebooted.
Now TWRP recovery worked and I was able to install a new custom rom.
Backups made with version 2.2.1 or grater work correctly for me now.
Thank you Thank you Thank you!

hey Im sry I never posted here b4 but I think this thread is the closest to the problem I have. My tf300 jad 4.1.1 ota update, i decided to change the rom since it seemed to have so many advantages. I installed TWRP correctly and according to the process I made later with debugfs tool I got root. It was all good but then I messed up, I installed Hydroponyc rom without backing up my rom and from then on, all hell broke loose. I can acces Clockworck (I changed TWRP for clock thought it might help......) and fastboot but any rom I install it doesnt go past the first asus logo that says device is unlocked on the upper left of the screen. Is there anyway u could help me please? Forgive my noobness I never posted here b4 I dont know if Im breaking any rule but i dont wanna wind up with a very expensive paper weight.
Did I brick it?

hey I was super frustrated by this but I took some time out and then I found this post I tried it and it worked perfectly give it a shot
Looks like partition sizes chaged with the Asus update. I couldn't flash CM10 or any other rom as well (signature mismatch). If you installed the official 4.1.1 update, you need to manually install it again. Older versions and rollbacks wont work unless you push to some trickery mmcblk0p4, but that's another thread in itself
Download the JB update from Asus's website (if you still have it, that's fine) and extract the blob file. Put the blob file in teh same directory as your fastboot. Boot your TF300 into bootloader and enter:
fastboot -i 0x0B05 flash system blob
It will take a while to install, so be patient. Hope this helps

you can flash the file named "blob" extracted from stock JB zip file(download from ASUS website,now there is only US SKU,10.4.2.29),it's about 7XX MB,then use the command "fastboot -i 0x0B05 flash system blob" (put the blob in the same directory with fashboot),It will restore your JB OS.till now,other rom can not work by this way.

What if you can only boot to APX mode? I only have the option of using that because my unlocked bootloader got erased in the process of updating to JB. Is there a way to install a bootloader using fastboot? Or will it only work with an existing bootloader?
In other words, when I issue the fastboot command
fastboot -i 0x0B05 flash system blob
I get "waiting on device" and nothing happens after that.
Thank you, this worked !!!!!!
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!

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...

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?

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...

Im following the instructions of post forum.xda-developers.com/showthread.php?t=1720980
Hi, I have the exact same error message after installing the latest firmware from asus (ww_epad-10.6.1.8-20130225) and flashing cwm recovery.
Flashing via fastboot works fine and I have already reflashed the blob file and reflashed cwm recovery. still the same issue: "Key driver not found" and upon chosing entering RCK it freezes. OS boots fine, no issue here. Any clues? Should I flash the stock kernel from Asus?

well, I am using a win xp machine for fastboot. so I don't have the same issues. fastboot works fine, so that I use the normal fastboot process to flash the system and the recovery kernel.
I finally got it to work again by flashing the newest TWRP instead of CWM. It seems CWM does not yet work on the latest firmware.
I followed this guide for flashing TWRP with fastboot. This version actually also just asked me, if I want to root the device, I clicked yes and it was rooted. Perfect.

I am in EXACTLY the same boat as you. The only difference is that I flashed TWRP instead of CWM. I finally decided that it was time to root my tablet...got tired of the lag. IIRC I've gotten the "key driver not found.. booting OS" error message since doing the OTA update to 4.2 (I did this prior to rooting.) Everything SEEMS to be working okay, but this bugs the heck outta me, and I'm sure it can't be a good thing. Hoping somebody will chime in with a fix for this. I've searched and searched to no avail.
I configured nvflash on a new unrooted, unlocked TF300T, running the 9.4.3.30 firmware by following the directions at. androidroot mobi t3_nvflash. The AndroidRoot9.4.0.30r01 bootloader and nvflash were installed and the tablet was successfully booted into APX mode, nvflash was bootstrapped using wheelie, and the bricksafe.img, factory-config.img and unlock-token.img files were generated and saved.
Unfortunately, I was not able to use fastboot to install clockworkmod recovery or enable root. Flashing was attempted initially using Windows XP and again later using Ubuntu 12.04, with the following result:
# fastboot -i 0x0B05 flash recovery recovery.img
sending 'recovery' (5306 KB)...
OKAY [ 2.443s]
writing 'recovery'...
OKAY [ 2.058s]
finished. total time: 4.500s
# fastboot -i 0x0B05 reboot
rebooting...
All seems well, but recovery does not install, the tablet does not reboot, and will not accept further flashboot commands. It has to be restarted by holding down the start button. On restart a blue line quickly flashes across the screen, but on boot to fastboot/recovery mode there is no icon to access recovery.
Device: TF300T Transformer Pad
Android Version 4.0.3;
Build Number: IML74.US_epad-9.4.3.30-201220604
Questions:
To what partition/folder is the recovery image flashed on the TF300T?
Has anyone ever actually used nvflash to unbrick a TF300T? If so will someone point me to instruction how to repair/restore the original/unlocked bootloader using nvflash, or something close?
Is there a procedure to install CWM recovery using nvflash?
Thank you for your help, any assistance is appreciated.
Some Hard Learned Advice
I'm still unable to flash a custom recovery, but the good news is that my tablet works although it's not rooted, and I have a functioning nvflash
If you want to avoid my problem, I recommend that you root your tablet before you install nvflash. Remember that at present, you can only install nvflash on a TF300T running ICS but, definitely do install nvflash. Follow the instructions from the folks at androidroot.mobi, but don't forget to root first.

I believe you would want to follow the guide in the General section for the TF300 to upgrade from ICS to JB 4.1.1. Its called
[GUIDE]Upgrade your TF300t to Jellybean 4.1, root & remove bloatware[Noobproof]
Then update to the newest version of 4.1.1. Then finally put a version of TWRP that is compatible with the 4.1.1 bootloader on the device. Also when I Installed the recovery I used the "recovery.blob" file, not the .img

Since you already have installed nvflash and have your files I'll try to answer with that in mind.
First I suggest using twrp of the latest version for ICS not cwm.
The partition for recovery is recovery. The commands you provided are correct (I do suggest using a blob file with fastboot - and twrp not cwm).
For unbrick with nvflash yes others have here is a link with the commands needed.
Remember you only have to flash what is needed to recover your tablet.
Did you perhaps download the wrong version of recovery? There is specific versions for ICS and JB 4.1.1 and JB 4.2.1. However I think of you use a blob instead it may work. But as above posters said, I would update to the version of stock android that you want. Cuz when you update your going to loose root and recovery anyways so why bother putting it on there? So I wouldn't flash anything till you are on the version you want to root. Also it will be safer to upgrade with stock recovery. TONS of people have bricked by updating to 4.2.1 with an incompatible recovery. You've been warned.

No USB icon
Hi Guys,
I have 4.2.1 installed and want to move up to 4.2.2 however i now notice that when I try to boot back into recovery I have no USB icon to reinstall TWRP. I used TWRP 2.5 to install 4.2.1. Can someone explain how I can get TWRP back onto the system and get my USB icon back so I can keep up to date.
Your assistance will be gratefully appreciated.
Cheers
Asus TF300T
The 4.2 bootloader doesn't have a separate fastboot mode. As soon as you're in the bootloader, fastboot starts. There's no icon to select because it's already in fastboot mode.

The new 4.2 bootloader has no usb icon. When you enter the bootloader do not press any keys you will automatically enter usb mode. Watch the upper left for a message showing fastboot started..

The reason no one from TWRP is fixing it is because there's nothing to fix. It wasn't a TWRP bug. It was ASUS's bug, and they fixed it in the most recent OTA update. I would suggest using fastboot to flash back to stock to get your stock recovery back, then update to the most recent OTA, then you can flash TWRP back.
Edit: What I just said was actually kind of in the OP of the thread to which you linked, in bright red letters. It said that you need to be on the very latest OTA for that version of TWRP to work. In fact, those were, more-or-less the very first words in the post.

Hi sorry its taken me time to get back. I've had some issues with this I now get a double TWRP screen that I can't do anything with and when I can get back to a normal screen it asks for a password all the time and I've tried to factory reset from inside (not from twrp) and it does nothing at all
So I'd like to try and reset back to factory and start again if thats possible? And is there a good tutorial on this?
Cheers & thank you for your assistance

If you want to go back to stock, just flash the stock firmware in fastboot. There are lots of guides for flashing stock ROMs throughout the forum.

I found the issue you need to go to this version of TWRP (which I may add is not on the download list fromTWRP) http://goo.im/devs/OpenRecovery/tf300t/openrecovery-twrp-2.4.4.0-tf300t-4.2.blob
I now have TWRP working and I'm running 10.6.1.8 however I find that I can not factory reset or use TWRP to upgrade firmware to 10.6.1.15 or any other ROM. The device says "Device is unlocked" & I'm also having an issue trying to locate a good tutorial on how to flash new firmware or kernel with fastboot. If anyone knows of a great tutorial that is easy to follow and also how I can obtain any of the required .img files that would be great.
This is getting frustrating now not being able to flash anything at all (angry)
I'm also getting an error message when I try to use the Asus unlock apk (An unknown error occurs,which maybe a network connection issue. Please wait and try again later) yes done toooo many times.
I've now even tried to flash CWM instead of TWRP and nothing ....the device boots fine and works fine I just can not factory reset, or install a new or updated rom from TWRP.
Message from TWRP :
Updating partition details...
Simulating actions...
Updating partition details...
and TWRP says Successful but nothing happens
can someone help me out here before I rip what little hair I still have out ggggrrrrrrrr
So I flash the stock rom on it without thinking and now it wont let me flash a recovery to the tablet threw fastboot or goomanager and it wont update throguh asus update but its booting fine and wont take any updates at all i need help being pointed in the right direction!
I flashed the wrong bootloader i think and how do i flash the correct bootloader without a recover?
in fastboot im getting the error: cannot load 'file name' :no error weather its cm or twrp it wont load it and i dont know what to do please help
First of all it would be important to know what bootloader you are actually on. You do not want to flash a recovery that is not compatible with your bootloader!
So boot into the bootloader with Volume Down and POWER and read the tiny script. From there select the Android with Volume Down and boot back to system with Volume Up.
And then please report in detail what you are trying to do in fastboot, which commands you use etc.
Without knowing what you are doing we cannot tell you what you are doing wrong.....
First step: In fastboot command: fastboot devices - Do you see the serial number of your tab?

So you are on an ICS bootloader with a JB rom... How the hell did you manage to do that?
You did not answer my question about fastboot. What you tried and what did not work.
But anyway, how I would proceed, just to get you back into safe territory, is to download the latest Asus firmware 10.6.1.14.10, unzip the downloaded file once and copy the resulting zip to the root of your internal SD.
Reboot, and hopefully the stock recovery will recognize the update file and flash you to JB 4.2.1 (which BTW is the latest version for our tabs - there never was, and probably never will be a 4.2.2). Flashing the stock firmware will replace the bootloader.
So from there you just have to get fastboot working, flash the latest TWRP and then the custom rom of your choice COMPATIBLE with your bootloader and recovery.
If that doesn't work we have to try something else. But try this first and report.

Read the text in the upper left corner - current bootloaders enable fastboot in the bootloader menu automatically.
