Okay so I seem to be bricked in some way. I've tried fastboot flash a couple times using OEM images "MZ600-HRI39" I have the MZ600 so that should be correct. Attached is my log of what I did, I eventually tried erasing each partition and rebooting to see if that changes anything, theoretically I thought I should be stuck since everything should be erased. However, I still get the Encryption Unsuccessful screen. Went back to recovery and tried wipe/user data and cache get BP fail with user data wipe and tried e: dev a few times before it stops. Then reboot and same. Any help or suggestions would be great. Thanks in advance.
P.S. I just want to get a stock IMG in so I can OTA to current; trying to keep stock so I can exchange at BB for newer tablet.
I just kept the log short only showing I erased each partition, but pretty much same result with flashes. All performed and got OKAY.
I think I got it. So you erased all the partitions... No problems when erasing data and cache, but the worst error you did was erasing "boot" and "recovery", so what I recommend you to do is:
1 - (easier way) download LordAIOTool for LINUX! (Windows is outdated...) and use Stock Install tool
2 - (harder way) follow this guide:
- Open cmd
- Plug your Xoom on fastboot
- go to Stock Files folder
- type fastboot flash (not sure if it's flash or install, anyway, I think it's flash ) boot boot.img (if downloaded from Motorola)
- type fastboot flash system system.img
- type fastboot continue
- Pray lol
Now all I wish to you is Good Luck

***I still get to Encryption Unsuccessful screen.....my thing is I don't even feel like it's flashing over anything, but not sure if that's possible. Almost like some write protection to the partitions.
Any other suggestions or does anyone need a paper weight?
not sure if this means anything either or gives a better ideal of the state of the device, but when I try wipes i get.."E:format_volume: make_extf4fs failed on /dev/block/platform/sdhci-tegra.3/by-name/cache" yet it states cache wipe complete. Then a bunch of failed to mount and can't open.
Try reflashing a custom recovery and with it try formating everything... Then try again everything from my other post again good luck

I've tried custom recovery, via fastboot flash recovery "recovery".img with no luck. It doesn't stick. Do you have any experience with RSD?

What do you mean with It doesn't stick?
Can you get into the recovery menu?
You could also do a oem lock and oem ulock again.
Then reflash everything again (boot, system, recovery if needed).
I go to flash with fastboot and when I try to access via power button, then volume down button I just back to OEM recovery. Was thinking if I try to rebuild system from bottom up that should clear everything out (bootloader, then IMG files). Was wondering if RSD would do that?
just noticed this in recovery when I perform wipe cache partition I get this message "E: format_volume: make_extf4fs failed on /dev/block/platform/sdhci-tegra.3/by-name/cache cache wipe complete".
So frustrated right now.....REALLY appreciate all the help!
Lord do you know how to enable USB debugging from fastboot, RSD, or OEM recovery? Found a forum mentioning a lock if OTA updates performed.
http://www.arvydas.co.uk/2012/05/installing-android-4-0-3-ice-cream-sandwich-ics-on-motorola-xoom/
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:

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'm sorry I don't have time to post links right now but try to download and install flashboot. If you get that far, you can then download almost any recovery solution and see if you can flash it. I believe the command will be:
Code:
Fastboot -i 0x0B05 flash recovery <file location>
Please read up a bit before you try this. It should flash just the recovery so it shouldn't intefer with the OS or root. Please use caution and read, read, read on the topics (fastboot, TWRP, CWM.)

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,
I had a stock tf700, running ICS (4.1.1) and I followed the really good guide by sdbags on how to unlock/root.
I rooted it with no problems, and used the ASUS unlock tool which seemed to work (it says that my device in unlocked), but now I am stuck in a boot loop
It fully boots up and can stay working for about 30 seconds to a minute and then it just reboots.
I can get access to the bootloader but I have no idea what I'm doing. I haven't installed TWRP yet either.
I'm sceptical of just hitting "wipe data" as I hear I could brick it for good.
Any help would be greatly appreciated....I'm really at a loss!!
I've seen this behavior when the kernel was newer than the bootloader and incompatible - but if you haven't installed anything yet this is unlikely to be the reason for your problems. You can try to enable USB debugging, run "adb pull /proc/last_kmsg" and see if that file contains any interesting information about the reboot.
If you want to wipe data, you can choose RCK from the bootloader menu - if it loads the stock recovery (Android mascot with red triangle), you know that the recovery is good and you should be safe to run "wipe data". I have only seen the stock recovery once and that was almost 2 years ago, but if you press the Power button in the recovery, you may even get a menu from which you can wipe directly from the recovery (use power and volume keys to navigate).

Thanks for the advice. I chose RCK from the bootloader menu but it just boots normally....no Android mascot. Am I doing something wrong there?excuse my complete newbness)
Is there a big risk in running "wipe data"? If I haven't installed any custom ROMs or flashed anything yet, is the risk of a brick slightly reduced?

There's not much one can do wrong here - turn on tablet and hold volume-down until the bootloader menu appears, then hit volume-up to confirm "RCK", that should boot the recovery. If it starts the regular OS instead, something is wrong.

I wouldn't risk it if you can't even get to recovery manually ("wipe data" uses the recovery to wipe - if the recovery doesn't work, it's a hard brick).
Try installing TWRP via fastboot.

Thanks for the advice. I took a couple of days break but I'm back trying to fix it.
I tried RCK and it just boots to a dead android man with the triangle error.

Also, I tried flashing TWRP via fastboot but after entering the flash recovery command, I keep getting an error message after entering saying "Too many links". Do you have any idea why that may be? I'm flashing TWRP 2.6.3.2
Thanks in advance!
Asus TF700T Tablet fix
Try this, it worked for me....and the standard disclaimer: I am not responsible if you misunderstand instructions I give here, if my instructions are wrong, if you forget to charge the battery and the tablet dies halfway through a flash or if your house goes up in flames. YOU DO THIS AT YOUR OWN RISK
Ok, so I think that I may have lost power during an upgrade (can’t think of any other reason for it!!) and ended up soft bricking my Asus TF700T tablet and recovery attempts would just lead to the dead Android with a red triangle with an exclamation point in the middle. My warranty having expired with Asus and any attempt for their assistance proved fruitless.
Well I researched and tried absolutely everything out there – (Hard Reset, installing TWRP, used a tool called Motochopper and flashing a custom ROM, downloaded and renaming .zip files, putting it onto a Micro SDcard is formatted Fat32, Scotts Tf700t Recovery etc.etc. etc.)
I even took it to the local shops and paid to have one of the Mobile Technician pop-up stores take a look at it, then a friendly techno geek………all with the same suggestions most likely a motherboard/hard drive problem.
My Asus TF700T tablet eventually ended up with just the plain white ASUS logo in the middle of the screen, some small print in the top left corner followed by the dreaded words “Unrecoverable Bootloader Error (0x00000000)”.
During all of my research I was led to believe that if you can still get to the recovery screen, where you see the 4 icons, all is not lost so I persisted.
Here is the instructions that I followed that restored my TF700T:
Download and install ADB, Fastboot and the required drivers - Download and run this cool little tool which has it all packed into one: [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
NOTE: at the moment Fastboot seems to have issues with Windows 8
This awesome tool installs the ADB and Fastboot.exe to a folder on your C:\ drive (look for a file titled “adb”) as well as the corresponding drivers. This takes about 15 seconds to install following the prompts.
I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:
E:\asus>fastboot erase system

fastboot -i 0x0B05 flash system c:\adb\TF700T\blob - depending where you stored your blob, also this was the first time that I saw the loading bar appear on my tablet.
It will now go through the process of reinstalling your Android stock ROM and you should see the something similar to the following:
E:\asus>fastboot -i 0x0B05 flash system e:\asus\blob
erasing 'system'...
OKAY [ 1.731s]

fastboot -i 0x0B05 reboot
E:\asus>fastboot -i 0x0B05 reboot

finished. total time: 0.020s
E:\asus>
I disconnected and rebooted My Asus TF700T and I now have a fully functioning Tablet with a stock ROM.
It has been reported that after completing this you may have some issues getting back get into recovery, hitting RCK and getting the dreaded dead Android (with a red triangle with an exclamation point in the middle). I have not attempted this but have been led to believe that flashing TWRP 2.7.0.1 via Fastboot works.
