It will only work on UNLOCKED devices
It requires access to Fastboot to prepare device first time
It won’t work on fully bricked devices (See 2.)
You need to keep files safe!
If you upgraded to Offiical JB it *won’t* work!
i'm not have fastboot and i'm on Official JB
i have try to enter on APX mode but i can't

did you try to install the asus pc sync (it shoul install the driver for use adb & fastboot) and after boot into recovery
from prompt you should be able to use adb
write adb devices
and if you can see the code of the devices may you can still have a possibility to flash troght adb

ok man i understand the problem today
i have flashed the last TeamWin Recovery but not compatible with 4.2.1 but 4.1 stock rom and now all partition can't be mounted in recovery, i have found adb in broken recovery and push recovery img for flash with dd command and all done in shell but nothing flashed !! then "adb reboot bootloader" for try to reflash with fastboot, same story all done in shell but nothing flashed !! ok no problem i try to boot android in boot menu and damn partition is ok and android booting !!!!!!! :laugh:
ok remain 2 way. use dd in terminal emulator but can't without root permission and use nvflash but it's not work with JB confirm ?
waiting for a tool using an exploit for root from internal android and try dd or next update for nvflash.
any idea ? and sorry for my very bad english

and what do you think about ?

if you can boot the system may you can verify again the bootloader whit asus tool from the website maybe for any unsense reason it's locked....

ops wrong tread

Ok, I just tried some stuff and:
1. I can also access fastboot and OS.
2. Trying to flash modified TWRP with fastboot freezes bootloader.
3. In-system can't open .RAR files.
4. After manually transfering unpacked V8 unlocker from PC it says there's an "unknown problem" when trying to install unlocker. It supposedly upgraded from V7 to V8 app without problem.
In bootloader it says at the top of the screen that "Key driver not found... Booting OS". After that it lists bootloader info ( v. 1.00 e ).
Looks like recovery's bricked with some further issues in the OS itself.
EDIT:
Bricked the OS. Tried reflashing stock system and now bootloader freezes when trying to boot OS. My guess would be that fastboot can still erase stuff but most likely can't write ( at least not properly ). Google/Asus probably know of a way to restore our tablets but Asus clearly prefers to replace motherboards.
I have to think whether it's worth it for me to replace the MB but most likely will just sell the thing for parts.

whan you try to re-flash the system somthing goes in the wrong way? do you still have fastbooy access? was the usb debug on?
sorry but which rar you can't open?

imho that won't be successfull. I suggest you start from scratch and flash stock then boot into it then flash recovery and then custom rom
see: http://forum.xda-developers.com/showthread.php?t=2179759 (post 12)

Now my device stuck on asus logo...
Now I have direct access to fastboot (with power+volume down) no needed the adb command: adb reboot bootloader
I can flash the firmware blob, recovery, but unsuccessful
Now, if a go to bootloader and select the rck icon or android icon i get that message: Unrecoverable bootloader error (0x00000000).
How to fix this?

Mainly it happens when You go to TWRP after flashing it without reboot. Reboot should fix it, if not - reboot tablet after flashing TWRP.

Well what had happened to me was I already had an old version of TWRP on my internal memory and I put the new version on my SD card which I wanted to flash. When I flashed twrp.blob, it flashed a very old version with an incompatible bootloader (whoops) which gave me the password error. So I put the new version on my internal memory, flashed twrp.blob again, and it worked.

delete the 2.1.4 trwp from your tablet altogether
The do this exactly from fastboot:
Download the file, check the md5, rename to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere). Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm). The device will now be in fastboot mode. Plug the device into your computer. Run the following command via the command line:
Code:
fastboot -i 0x0B05 flash recovery twrp.blob

So put the 2.6 -42 TWRP in your fastboot folder, then run the command.

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.

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 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:

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:

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:

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.

[Q] Load TWRP 2.8 fails

I connect the N5 to my PC (Windows 8.1) with a USB cable and in the command line I write:
> adb kill-server
> adb start-server
> adb devices (to see the N5)
> adb reboot bootloader
and I wait till I see the fastboot screen in the N5. The I write:
> fastboot boot openrecovery-twrp-2.6.3.4-hammerhead.img
It starts ok.
But with the last TWRP recovery, don't work:
> fastboot boot openrecovery-twrp-2.8.2.0-hammerhead.img
At first N5 starts ok, I see the blue screen, but then restarts in Android L.
Any idea?

No idea, but it just reboots for me but 1.0 works as expected. Strange

I had the same problem but this worked for me.
1) install an older TWRP that has work for you in the past. maybe 2.8.1.0 or older.
2) disable MTP
3) reboot into system.
4) reboot into recovery and flash 2.8.2.0
5) reboot and it should work. it worked for me.
now each time you use MTP you’ll have to re-disable MTP

He said he doesn't wanna flash the recovery permanently just boot it
Why is that, OP? Why not just flash the latest recovery?

Thanks !!

I've made some tests.
This recovery loads ok:
openrecovery-twrp-2.6.3.4-hammerhead.img
openrecovery-twrp-2.7.0.0-hammerhead.img
openrecovery-twrp-2.7.1.0-hammerhead.img
openrecovery-twrp-2.7.1.1-hammerhead.img
openrecovery-twrp-2.8.0.0-hammerhead.img
openrecovery-twrp-2.8.0.1-hammerhead.img
This one hangs out and don't start:
openrecovery-twrp-2.8.1.0-hammerhead.img
And this one starts (I see the blue screen) but reboots and the starts Android L:
openrecovery-twrp-2.8.2.0-hammerhead.img
The command I run is allways ' fastboot boot operecovery-twrp-x.x.x.x-hammerhead.img'.

I know yuou said no flash, but you should try and flash 2.8.1.0 and see if it boots. If it does, check if MTP is enabled. If it is, disable it then try boot again

I'm so sorry.
Not, I not checked the md5. For the 2.8.0.1 there was an error. I dowloaded again and now it has the correct md5. And starts ok.
But the 2.8.0.2 had the correct md5 (not need to download) but keep restarting.
Thanks !!

The restart happens when MTP is enabled on 2.8.2.0 so the fix is to boot into older version and turn off MTP then newer version will work. Please FLASH 2.8.1.0 as suggested and check it is off. The reason I say flash is that because you cannot boot it.

After the comment of gamer.11 I've checked the md5 of the failing 2.8.0.1 and 2.8.0.2. The first had bad md5, I've dowloaded again, but the second was ok.
I update the results of my tests.

I have MTP disabled in my phone. Ok, if this is the problem I'm going to wait to the next release, to see if it is corrected.
Thanks !!

Not in your phone, in your recovery. It is a different setting. Yes just wait for new version, I think thats best.
