[Q] No fastboot anymore, only XDA Mode possible, - Asus Transformer TF700

Hello Friends and first I have to say sorry for my english.
OK, I try to tell whats happend.
2 Days ago I would like to flash a new rom on tf700t. For that it was neccessary to change from TeamWinRecovery to ClockworkModRecovery.
To do this at the easiest way, I have done this Job with the Rom Manager App.
That was my first error.
After Installing I reboot my tf700 and was surprised, TeamWin was still there...
Ok I have created a full backup, after that I performed a full wipe.
After that I have rebootet again, but know TeamWin was not there anymore, Clockworkmod was also not not there.
Booting with Power + Vol Down Fastboot mode is starting (I think so) 3 Symbols in the Middle.
Starting RCK Mode, but nothing happens, only a text left above, Recovey Rom is loading (or somthing like that)
Booting with Power + Vol Up APX Mode is running. Black Screen and Pong on my PC. Nvidia Driver installed.
OK later, verry late at night I have by mistake Used The Wipe Button, I dont wont to do that but I have pressed the wrong button.
Now the follow things happend by Booting.
Only Presss Power:
Tab is starting to Asus Logo in the middle, in the left corner abowe The Device Is Unlockes. Nothing else happens.
Press and hold Power and Vol down: The same like above No Pong on PC, the same screen like starting the tab normaly.
Press and hold Power and Vol up: APX Mode ist starting.
I have many Full Backups TWRP.
I have the Stock Asus Rum on SD Card.
I have the nvflash Package for my tf700t.
I have the flatlinetf700t.img
And many other files.
Oh I dont have createt bevor any blop files.
What I will ask you is: Is it possible to repair the Tab by using nvflash?
I think the bootloader is defect...
What is needed for that

Not without the blobs.
"Wipe data" + broken recovery + no blobs for nvflash = hard brick. There is no known fix.

Is it possible tu use blob files from an other tf700t 64gb??
I have here a original asus tf700 Stock rom, wich I have full extracted twice. So now I have the rom as a blob file wich was in the zip. 800 MB.
What can I do with that file?
Here I found something to use the android toolkit but it cant work, there is no fastboot mode anymore. If I try to use fastboot, power and Vol down, nothing happens, there is no device installed at pc, only in adb mode, but android toolkit could not handle adb mode.

Last hope is to use some other blob files..
Whats about RMA? Prices for that job?
Thanks.

You need the blob files from your device. They store keys particular to yours. When you started the nvflash process it sounds like you never completed it. That means you have no means of recovering.
List the files you have.
RMA will set you back between 200 to 300 dollars but ask Asus for a quote. You might be better off selling it for parts and getting something newer.

What I have is all from here, means the nvflash files for my tf700t.
I also have the original asus stock rom for my device and some other roms, twrp backups and so on...
The most is not usable while there is no fastboot / adb mode possible.
I have never read something about some blob files needed for other devices...
I dont understand what for blob files I need to bring recovery back. Thats all I want to have.
I tried to flash via nvflash the stock asus extracted till to a blob file. I remember nvflash wrote than somewhat like, no blob files found...
Maybe its really time to say goodby to this ....

If you followed the instructions on that page including the wheelie part to extract and save your blobs then your device is salvageable. The question is did you?
If yes you can use this guide to restore.
http://forum.xda-developers.com/showthread.php?t=1927818&highlight=nvflash
If no, sell the device for parts as it is dead.

Thanks again.
I have asked Asus for Support and I post again after an answer from asus.
**** happens. That with the strongly recommed to do to make this device bricksave has to be placed on every first sites about this Thing.
Are there more devices who needs those files (means blobs)

Get a used motherboard on Ebay and replace it yourself. Sure to revive your darn tab for much less. What is it an Asus technician can do that you can't? It ain't rocket science after all. Go to this site and learn how to take it apart.

I dont know, what asus can do...
I have now looked many days for a mainboard for my device. Only 32GB Version are listet by ebay.
Maybe I have to wait...

Asus will do nothing other than charge you hundreds of dollars to replace the main board.

Since you are giving up and looking for a new mother board, you can PM and we could try a few different things to see if we could wake it up... If you have some spare time to waste then you could give it a shot, hahaha....

recover options for bricked TF700 Please Help!!!

I just got my TF 700 and rooted an unlocked it, and all was ok, but then installed an app from the app store and now I only get "booting recovery kernel image" I was able to boot to APX mode install the driver and use Universal root toolkit for the TF and install the firmware from ASUS website but I think the boot image file is the problem. The transformer.bct is not for the TF700. Thanks in advace for any help.

No I cannot boot into recovery only APX mode and use nvflash. I am able to flash files. I have flashed the factory firmware from Asus. I think it is the boot image that is still bad. I used the recovery tool BRK_RootKit_v8.0_final to flash the image file but it tries to flash the original TF transformer.bct boot file. I think If I had the correct transformer.bct for the TF700 it would work.

AFAIK the nvflash method doesn't work for TF700 and is possible that you really bricked your device... The only solutionn i can see is to flash a recovery in fastboot mod and flash the Asus stock from there,but if you can't even boot in fastboot then i don't see any other way to recover the device.

Sorry mate,but according to this --> http://androidroot.mobi/2012/07/15/nvflash-for-tegra3-transformer-prime/ <-- i don't think you will be able to use nvflash for recovery and it clearly states that you need to get fastboot working in order to use that method. (to get in fastboot mode press Volume down + Power and release the buttons when the message about having 5 second to press Volume Up shows...if this work you will get to a menu with the "USB icon" wich means boot in fastboot mode).
P.S : Can you tell us why you had to mess with nvflash?That is the most advanced way to recover/backup the Transformer 101/201 series and you have really high chances to brick your device for good.
EDIT: I don't think someone here will be able to make a backup for you with nvflash...it will only lead to more bricks.
EDIT 2: Can you please tell us the name of the app that bricked your device so we can avoid other people bricking their device?
The app was transformer reboot recovery I think.
I only used nvflash because it was the only option left as the tab wouldn't work with adb or fastboot.
I guess I'll keep it as a paper weight.

Yes,i also used that app with no issue,but one of the developers behind TWRP advised to not use it at all,because if for some reason your recovery gets corrupted (that app send a custom command to boot into recovery) the device will boot loop trying to get in recovery and without nvflash we don't have many options to recover from that.
"
KEEP AWAY from that app for the moment,just stick with the old good " Volume Down + Power and then Volume UP " method to get into recovery.
Same issues here as well
I had rooted the TF700 ( as i wanted to download a market fix for my region, as i wasnt able to download GTA III) and had installed the eris market fix app :sillymy stupidity) it changed certain values to the original market application. After a reset/ reboot i was stuck at the powered by Nvidia Screen. I tried colding booting/ wiping etc non would work. I tried reinstalling the boot/system files through fastboot still no luck. what i cant understand is the fastboot setup seems to work when i id the Device it shows:
"? Fastboot"
i can reboot, push the system/ boot and recovery files, but cant boot into recovery mode. i have even pushed the twrp 2.2 file through fastboot. My only bet would be to boot into recovery so that i could mount and push custom roms.
I have even tried flashing the rom update through the following command "Fastboot flash update filename" however i get the archive cannot find android-info.txt error .
Is there anyway i could boot into recovery. (previously i could boot into recovery, but when i formatted/ erased the system and boot files i only get 2 options 1. Wipe Data & Cache & 2. Fastboot (USB). I tried holding the vol down button and the power button but that just puts me into blank screen mode and the APX driver pops up on the device manager.
I had to uninstall all my current drivers supporting asus and manually select the asus fastboot interface to get the fastboot working.
Any ideas would be helpful.

1The first step is to get your recovery back and working...here's a how-to:
1) Download the recovery from here
2) Follow the instruction on how to flash the recovery in fastboot mode
If the flash went good and you can get in recovery mode follow this steps:
1)Download the 9.4.5.26 firmware from Asus site (the SKU for your region)
2)Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3)Put the extracted zip to a MicroSD card
4)Insert the MicroSD card in your tablet and boot into recovery
5)Install the zip from recovery and restard when done
If all goes well your tablet will be again up and running
Ray of Teamwin
:good::good::good:Thanks a million, seeing the team win screen relieved me. The only problem is i cant boot into recovery (teamwin screen is visible)through the wipe data mode, wherein everything is wiped and it reboots automatically. I cant seem to force the table into recovery without this is there any fastboot command which i can use to force the tablet into recovery.
Need Stock Boot, Recovery, System img
Still no luck with the recovery mode. Every time i wipe the device it automatically reboots. I was wondering if i could get hold of stock recovery, boot and system .img files so that i can push them or flash them through fastboot.
i tried using the blob pack and unpack but i cant seem to get around the blob header thing.
Anyone to spare me stock .img files
End of Infinity
Okay my frustration has led me to "fastboot erase bootloader" and now i am permanently stuck in APX mode.
However as nvflash is not avaliable for tf700t i guess i wont be using this for quiet sometime. Unless nvflash is made available

There's a thread (I can't find it again) that talks about this "Reboot into Recovery" app and how it might be bricking TF700T's. This guy wrote in, because he could not get to the recovery menu at all any more and could not do the "PWR+VOL-DOWN" combo. Nothing would happen. Maybe this was the thread, I don't know.
An XDA Mod in another thread said the app *might* be bricking them, but was waiting for confirmation before posting that it does.
I wish to confirm that IT DOES BRICK TF700T's! IT DOES!!!
And there is NOT A DAMN THING you can do! Your PC will not even recognize that the device is connected! You cannot get to the little icons to pick USB Mode, or whatever it's called.
This is the free app, not the other pay one in the Market. I don't know about that one, but this one is called, "Reboot into Recovery" and if you can somehow find that thread if I don't and just copy my post there, I would really appreciate it! I just want to warn people, ya know?
Also, using ANY of the "ROM Managers", whether it's CWM's, or GooMgr's, will take away all ability to get to a recovery menu at boot, at all! The device will still work and everything and boot to your Home Screen and everything. It won't be bricked like the app listed above does to it, but it will take away your recovery menu altogether and the PWR+VOLDOWN thing won't work any more either.
You can Unlock the TF700T, you can Root it. But you cannot use ANY ROM Mgr and you cannot use that Reboot into Recovery app.
But the app I listed above WILL BRICK YOUR DEVICE BEYOND ANY RECOVERY METHOD!
Please pass this on, I am confirming the experience. It doesn't matter if others say it worked for them. It is bricking them at random and even one of the guys who reviewed the app (diff guy than the one who posted here) said it bricked his. It is happening! It is not the user messing up! I did do it right!
Thanks!
I'm not sure if you are talking about the app named "Transformer Reboot to Recovery", but that particular app works fine on the TF700 - I use it all of the time.
The only time that it *can* cause problems is if your recovery is already corrupt or there is some other issue, in which case it can cause a bootloop.
But, if there are no issues, it works fine... There is a risk involved, like I said, if there are pre-existing problems with your device, but if you know that everything is working fine on your device, the app mentioned above works fine.

No offense, but I think a huge problem in forums, is that people don't read carefully.
1) I think you are referring to the paid app. Read what I said about that.
2) You're saying what you're saying, in a thread started by a guy who had a running device and who didn't after using the app.
3) I said that it bricks them AT RANDOM.
4) Another problem with forums, is that whenever someone has a problem, A LOT of users want to post responses that ignore the users' experience and they want to act like the problem doesn't "really" exist. If multiple people are posting the same problem, then IT DOES EXIST. It just doesn't exist for YOU! But something working for you, does not mean it works for everybody and it does not mean there is a problem with their device, nor that they did something wrong.
5) And yet another problem with forums, is that when someone like me points things like this out, many users will respond by jumping on me, instead of those who try to make the guy feel like he's hallucinating and who, instead of trying to help him out, or just keep their mouths shut if they have nothing helpful to offer, think the right thing to do is to argue with the person having the problem.
These forums are for help and information. If someone has neither to offer the person, or at least warn others, then why are they responding at all? And why would anyone defend someone doing that?! It's ridiculous! But that's what typically happens, especially in XDA doe some reason (lots of snobs here, who like to prove they are, by doing as I just described).
The bottom line is, you do not run the app I talked about and even if you did, that does not take away from the experience that some have had and the best thing, is to avoid the app, because there's a risk involved and there is no recovery from it. I decided to warn people. You decided to tell us that we're hallucinating and that people should use the app. You did not carefully read what I wrote, or you would have checked the Market to see what the name of the app that does not have a pay version is. The one I am talking about does not.
I will tell you this. I am posting this from my laptop, because I had to return my Tablet and have a replacement shipped and now I have to spend a few days getting it all set up again the way I had it.
Avoid the ROM Mgr apps on the TF700T. And avoid the free app called "Reboot into Recovery". A user told me about it for my device, who had seen it used successfully. However, if you look at the reviews in the Market, you'll see that one of them says it bricked his *WORKING* *FINE* tablet and this thread right here has told you about two more. So just believe it and don't criticize, huh?
Okay Mods, feel free to jump on me again, just like last time.
I agree with many of your points, Zeuszoos, and thanks for pointing that out, but I believe there are many senior members at XDA willing to help if they have knowledge/abilities to do so, that's been my experience so far and hopefully it can be yours too. Of course, a little SEARCH won't hurt before posting one's problem, as you reasonably mentioned yourself
"reboot to recovery" has been in my apps STICKY thread in the sections "apps to avoid" (RED) for quite some time now after first reports of bricking users' devices started popping up and I believe it has helped some users who did a little reading before clicking...

[Q] Loaded Wrong TWRP on TF300T and can only access APX mode

Hello,
I loaded the wrong version of TWRP on my TF300T. When it rebooted it loaded CM10.1 just fine. I then rebooted a second time in recovery mode and I have been stuck at the ASUS screen with the "device is unlocked" message. I am able to get into APX mode but my research has shown that mode doesn't do me any good if I haven't ran a nvflash backup. I am stuck and I would appreciate some advice or suggestions. I wonder what the factory reset fee would be from ASUS.
Thank you for your responses!
what version where you on? what version did you load that you think you shouldn't? Can you enter recovery mode? fastboot mode? I used fastboot to fix my recovery TWRP just can't find the thread I got my info from.
if your seeing the asus screen like you say I don't think it has anything to do with your recovery. I just went though fixing my mistake and breaking my install of TWRP 2.4.4 patched had to install 2.5 TWRP and when I restored my backup 2.4.4 was back and working again. anyway while the recovery was broken I could still run the stock rom that was installed at that time. I think if your on the asus screen your kernel has an issue.
I don't know where I read about issues like this but I know others have had em and recovered search or someone else should be able to point in a direction but have hope doesn't sound bricked yet.

Thanks for the speedy response =)
Version History: Stock 4.1 -> CM 10.1 Nightly 0503 or 0429. I had CWM on it before trying to load openrecovery-twrp-2.5.0.0-tf300t-ICS.blob using the terminal emulator method. I think I should have loaded the JB blob but the warning on the TWRP site said to use that if you ran the offical OTA update, which I never did so I stuck with the ICS. It installed fine, then rebooted into CM 10.1 just fine. I then rebooted from there into recovery and have been stuck at the ASUS screen since.
The Vol + - button keeps me in the ASUS screen. Reset button keeps me in the asus screen. Vol + + puts me in APX mode.
I try running fastboot in APX mode but it hangs stating "waiting for device" so I don't think it'll work in APX mode.
Thanks.

Try waiting for the battery to die, then boot in CM10 and flash the correct recovery.

Am I looking at repair here?
If you send it in for repair, ASUS will charge you $198. I suggest you buy a replacement motherboard off of eBay and replace it with the one in your tablet. Also, to save other people's tablets from bricks, you may want to look into this petition.
if you get stuck in fastboot mode then there is a zip file I will find the thread again and it has cmd files that run the fastboot stuff. I was stuck not able to use fastboot commands and then the zip I found worked like a charm.
its a zip file called adb-t.. instructions where to put the twrp.blob in the folder and the update in my case 10.6.1.15.3.zip and it flashed it even though i couldn't manually do it. really wish I could find that thread but I don't have my laptop right now

Hope this helps you like it helped me out of my broken recovery. once you download and add the files you want its pretty easy. the script in english makes it pretty easy to understand what your doing and hope it works since I know my TWRP was broken I couldn't even sit at the recover,android wipe screen for more then 3 mins without it bootlooping. I put it on that screen while connected to laptop ran the recovery flash and all went well installing TWRP 2.5 which I then recovered my backup and that even restored my 2.4.4 patch TWRP like nothing happened at all. tablet runs great and have made 3 backups that work after all this.
Good luck

Power up your tablet while holding down the Vol- button, then wait until a menu appears on your tablet. Within 10 seconds, hit the Vol- button.
On your computer, run "fastboot devices". If it finds your tablet, then download the correct recovery (http://techerrata.com/file/twrp2/tf300t/openrecovery-twrp-2.5.0.0-tf300t-JB.blob), copy it to your fastboot directory, then flash it using:
fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.5.0.0-tf300t-JB.blob
Followed by a reboot:
fastboot reboot

I tried running through your tread but none of the commands worked on the script. Probably because I can't get fastboot to work. When it tries to load a recovery it just states: "waiting for device" and sits there. =/

Thanks for the info. I am unable to get fastboot to recognize the device. The only way the PC recognizes it is via APX mode. Download mode just sits there at the ASUS screen and windows doesn't see any devices.
Still no love. Am I bleeding out the battery correctly? I am just running the boot screen until it dies then I try to power it on again.
I popped the back open today to see how difficult it would be to replace the mobo, doesn't look too bad. Just having difficulty finding a good online guide.
Also, just so I have the terminology straight, when the tf300t goes into a "boot loop" does it ever leave the asus screen and go black or does it just hang? Mine never goes black, just sits at the ASUS screen with "the device is unlocked" message. The only time I can get it to leave this screen is when I do a reboot and hold the + sign. then it goes black and APX is detected on windows.
Just wasn't sure if any of that information was useful.

One other solution is to unplug the battery for 30 minutes, then plug it back in.

Ok,
Tried disconnecting the mobo, no love. Ordered a new one for 75$ on ebay. Replaced the mobo and now the volume button doesn't work. Checked all the ribbon cables and they're snug. Probably broke something but I can't find what, so I am thinking of sucking that up. I can control volume with the settings. The only downfall is without a volume button I can't enter the boot loader, so no rooting/ cwm.
Least I'm back in business for now! And another positive is the mobo I received was 32 gig storage so it's like I got an upgrade... with a broken volume button =)

Usually, the volume button does not fail. Remember the volume button connects to, but is NOT part of the mother board. If it feels stuck when you push it, that's because you snapped the back cover in wrong. You need to slide it in at the corner where the buttons (volume & power) are, then pop in the rest of it. Take it out and do it again.

[Q] Infinity with corrupted bootloader, bricked?

Till this morning my Infinity I was on CleanROM Inheritance 3.4.7 with TWRP 2.5.0.0 Recovery, this worked fine. However I wanted to switch to CROMi-Xenogenesis 4.4.1 so I flashed 10.6.1.14.4 WW Bootloader and TWRP 2.5, as said in the OP. Unfortunately after the flash my device is dead, maybee bricked? I can't power on my tablet, with power on - volume down I can't get into recovery anymore.
I can't remember exactly what I saw after the flash. There should be an blue bar but I can't remember I have seen it. I saw this bar before when I flashed another ROM. The tabled had enough battery power, 90 or 95%.
When I put the tablet to my laptop I saw the word APX under other devices. Windows and Windows update doenst't seem to have the drivers present, luckily i found modified Universal naked driver at this blog. So now I have APX, but no fastboot.
When I read this thread, there is not much hope for me. Or is there a way to boot in fastboot modus? Any suggestions?

I would figure the tablet is on somehow if APX is noticing it. Have you tried holding down the power button until it vibrates to force shut it down then hold the power and volume down to get back into the boot loader?
Just wanting to make sure because APX is useless unless you have you NVFLASH blobs.

Maybee Nvflash is an option for me?
If I read http://rootzwiki.com/topic/35086-gu...rs-guide-unbrickrecoverdowngradeupgrade-tf201 correctly you can flash Nvflash in APX mode.

For this procedure, you must have obtained a blob.bin file by installing the hacked bootloader while you were still on a 9.4.5.26 or older bootloader.
If you don't have this file, and you don't know your tablet's unique SBK (Secure Boot Key), which nobody outside Asus knows, then you can't use nvflash.
Ah, so Nvflash is no option...
I contacted Asus support today by mail. First they came with the option of reinstalling the operating system for about 75 euro. Is that realistic? Or is an motherboard swap necessary? In that case the cost are about 160 till 200 euro. Quit a lot of mony. Then Ebay seems a better alternative...

If you can't get into recovery and you're using the correct side of the volume rocker (left!) and it really, really doesn't react to holding the power button for eternity - then you're probably bricked
The question is why? And how?
This hardly ever happens on the CleanRoms...
Did you reboot into system after flashing the bootloader and before flashing CromiX?

I don't know what happened after I flashed the 10.6.1.14.4 WW Bootloader and TWRP 2.5 recovery. After a while the tablet didn't react anymore...
In a Dutch forum I get the suggestion to check Easyflasher (http://www.youtube.com/watch?v=BxNmK6uXfFE&list=PLudvvIZ2s2oHbCK2Gb8aZHIoPpABzwthA). But om http://forum.xda-developers.com/showthread.php?t=1688012 I read WARNING: IF YOU USE THIS ON YOUR TF201/TF300/TF700 YOU WILL BRICK IT so this will be of no use I think.
I wouldn't use this -- it has been reported earlier to brick.
Have you tried to get into the bootloader -- that's what Tylor rightfully suggested, but I find your reply ambiguous -- press and hold down the left volume button ("volume down") and while you do so, keep the power button pressed until you feel it vibrate. Release the power button, and when/if you see some icons, release the volume button.
You're based in Amersfoort -- do you visit Utrecht with any regularity? (I live in Hoorn, but work shifts in the UMC Utrecht so might take a look at it for you.)

I strongly suspect the Recovery, I also had issues attempting to flash a later version of Clean
Rom. It took a day of flashing to get the tab back to health. Along the same lines I have also had issues flashing my T'bolt and also my DNA. For the time being I am refraining from changes on the tab and DNA.
I have used both CWM and TWRP

I've done this, but I see no Icons.... For me it's hard to see if my tablet is on or off. But when I hold the power button for a long time it vibrates so I assume it's off then.

OK, so I went over and despite musicfreak having good ideas along the way, we haven't been able to revive his 700, and I'm not feeling too optimistic it can be done. However, I don't want to pass up the opportunity for _that to show off his immense skill once more (feel the pressure? ) and help musicfreak out.
In short:
- unit doesn't actually boot into the bootloader at all, apparently. Screen stays black, no white lettering anywhere. Not a single one. Dead as a dodo.
- only APX mode is available, by booting with VOL_UP pressed-- nothing else works (screen is oof, so I cannot tell if anything else is loading; Windows detects only APX device connected). No fastboot.
- the procedure for reflashing stock doesn't work at all, obviously, because there was a custom recovery (TWRP) -- still, grasping every little straw, we tried -- everything -- but the screen stays black.
My own 700 is detected properly in fastboot mode, so it seems unlikely we have a cabling and/or USB port and/or OS error (tried both WinXP 32-bit and 7 64-bit).
After the usual hassle of getting the drivers in place -- musicfreak's saving the day of installing the patched drivers (I though the patch had gone mainline by now) -- we haven't been able to get any further.
Is there a command we can get to the device in APX mode to detect what is causing this?
Is this recoverable? RMA?
Thanks for the help and insights, guys and girls.

Dead/broken/missing bootloader (or broken eMMC), or dead screen.

If you tried to enable fastboot mode blindly and the PC didn't detect it, then we can rule out "dead screen".

The only way to do anything in APX mode is NVFlash. Without the SBK (aka "unobtainium") or the "wheelie" tool and the matching blob, that mode is useless, as far as I know.

Yup, the two options you call out here were in my head, too. I got over to musicfreaks' thinking that the bootloader was actually working, but it soon turned out to be dead. Since the only mode Windows can detect is APX and neither adb nor fastboot give any reaction or meaningful reply, I guess musicfreak's 700 is deceased.
@OP: given the fact that even our guru knows not how to save your 700, it comes down to either salvaging the parts and selling them on their own, or selling the broken unit and dock together subtracting the repair cost.
Anyone having specific ideas which is better? (I'd veer towards selling it in whole, which at least makes sure you're not going to get stuck with loose parts...)
Yes, there seems no hope for my TF700 anymore....
I also think that selling the whole set (tablet and dock) is the best choice.
Unfortunately looks like a brick to me. Without nvflash the only option is to send it off to Asus if you want it fixed. Otherwise sell it for parts (Screen, digitiser, case etc)
I will, ýesterday I've put my Infinity on sale, see this at on Tweakers.net (in Dutch). Anyone interested here?
One thing comes to my mind: why can't the SBK be generated? Can't it be extracted somehow from the processor?
@MartyHulskemper: Have we tried to flash the stock rom from MicroSD card? I'm not sure.

Nope. If it were unencrypted, we could've tackled it ages ago and use it to unlock the bootloader without ASUS knowing. I have no doubt that the processor serial number or some other identifier does figure into the process, but we do not know the rest of the algorithm used.
As to your specific question: there is no use in trying to flash anything from the microSD card since we couldn't get into the bootloader at all, and therefore have never even seen a recovery of whatever description or denomination.
As I said when I was at your place: I was udner the impression you at least had the bootloader and fastboot access. Although it's probably hard working even then, it would not be without hope. Not having a bootloader, and not having Nvflash at hand, well... I fear it is without hope.
It has been a while since I post the last update to this thread.
In short: I sent my tablet tot Asus, they charge me 310 euro. After an email discussion with them without notice they sent the tablet back to me. I asked the shop where I bought it for repair, and now I nead some information for my email to them.
All this goed wrong when I flashed CROMi-Xenogenesis 4.7.0. Is flashing this ROM more risky then flasting CleanROM Inheritance 3.4.7? If so, why?
I hope somebody can explain this to me.

No it is no more risky than flashing any ROM. Flashing a ROM is not very risky cos even if you brick you will be soft bricked and usually that is recoverable. Your issue may have been related to the bootloader and recovery flash. Did you interrupt it - it should have rebooted on its own after the blue bar went to full?

[Q] Bricked TF700

Hi.
I own a TF700T and seems to have bricked it. Last status was: I had the latest stock ROM with root running and wanted to get a CM11 based 4.4.2 image from here. I downloaded it and used rom manager to get it installed. But the install script failed at some point and I thought the recovery might be outdated. So I used ROM Manager to update recovery... I tried CWM and TWRP option. Finally I booted up into recovery trying again to install those damn rom - I used the option to wipe all data / settings from the main menu and tried again to install the ROM which again failed (I do not remember the error message clearly). I gave up. I used the "reboot" option.
Now:
- Powering up gets me into the screen with the ASUS logo (left upper corner says "the device is unlocked"). Here it is stuck forever.
- Power + Vol-Down is same as just Power - I do not get into flashboot with those 3 small icons... I just get the ASUS logo and nothing else happens. Reset hole does not change situation. The device is pretty much "always on" now (till battery is exhausted) as long-press Power turns off and immediately on again
- Only thing that seems to work: Power + Vol-Up ends up in APX mode - my computer recognizes the device via USB at this point
Unfortunately I never did any set up to nvflash.
Do I have any chance to get this thing alive again?
Thanks a lot in advance,
q2.

Unfortunately ROM Manager does not work with the TF700 and you are not the first one to find out the hard way...
If you cannot find a way to boot into the bootloader to have fastboot, there's nothing you can do anymore without the NVflash blobs.
Did you try holding Vol - and then pressing the reset button in that little pinhole on the side of the tablet?
If you have ADB drivers installed on your PC you could try if you can establish an ADB connection at any point. If you did, you could issue the command: "adb reboot bootloader", which would enable you to flash a recovery and/or bootloader. This probably won't work since you need to be in the recovery or have Android booted for ADB to work, but worth a try anyway...
Admittedly these are very thin straws - but what have you got to loose?
Also: Just a few days ago a user here was stuck on a bootloop to recovery and couldn't get out of it. He left it alone overnight and all the sudden the bootloop sorted itself out... I have no explanation for it and it is unlikely to happen in your case, but you never know...
Good luck!
Thanks for replying.
Yes, I did keep Vol-Down (means Vol-Left) pressed while pinching the reset button. It did not help.
I will experiment a bit more. It's not really a boot "loop" - it gets stuck at the ASUS logo and this does not change anymore. Not overnight.
So far I could only see it being recognized as USB device in APX mode. Can you give me a bit background here? I have nvflash here. The blobs are not available anywhere on the net? Or why is that all a big fuzz? I used to have a Notion Ink Adam and APX saved my life several times, but the blobs were available to everybody. Nobody has the blobs here? Or are they device-specific?
I cannot believe that a today's device with a non-bricked bootloader and working APX is totally lost and even the manufacturer will only offer a costly RMA to replace the whole mainboard!?
Best regards,

For the TF700 the nvflash blobs are device specific - sorry.
Damn. That was the only answer I didn't want to read
Thanks a lot. So chances are gone, only RMA could help... I will ask friendly at Asus what costs they will charge...
q2.
Update:
Reply is here.
They only want to exchange mainboard. They of course know (and it seems that this is the only thing they know) that my bootloader was unlocked, therefore this is no case of guarantee for them. I know, I wrote to them that I just want to know how much they wanna charge me to fix this issue.
But: they don't want to tell me how much. They say they do not even know which revision and what hardware is inside my tablet, not even from my serial number. And I must first send them my tablet and they will charge me 95 Euro to check what's going on. And then they will tell me how much it will cost (and according to other threads I saw prices of over 400 Euro for a mainboard change - the TF701 successor model cost 450 Euro new in store)...
I somehow feel the need to reply that if they would've put only half the energy the put into logging who has unlocked the bootloader into the fact of making APX usable as a emergency recovery (as obviously not even Asus is able to generate a working blob for my device), they would have higher customer satisfactory statistics. I still just cannot believe a today's device lacks of all recovery options after a bootloader fails for some reason - as well as I cannot understand why Koush did not display a warning in ROM manager if problems are known to the community with this specific device (I mean the problem did not arise last week and ROM manager had tenths of updates since then).
I know that in the end all was my fault. And all flashing is done on our own risk. I will have to deal with it.
Phew...
Unlucky. It should be be stickied here somewhere that ROM Manager bricks the TF700 but then there is no guarantee it would be read. It is well known on this forum but that doesn't help people that don't visit frequently.
You can replace the mainboard yourself fairly easily. Watch the you tube vids on how to do it,. That is what I would do if I was in your position.

Unfortunately I'm stuck in same boat I tried to wipe out settings completely and clockwork mode was stuck and I was able to wipe recovery with TWRP or so I thought tried to reboot into recovery got stalled and now stuck on asus screen. I'm not opposed to buying a new motherboard but I find it very hard to believe that no one has come up with a solution to flashing the mainboard with the original firmware. I'm tempted to ask asus but I know the bill will be more then the tablet. Did you find an easier solution or do I just have to swap out the mainboard?

That's correct. You have to flash a modified bootloader and recovery. Done correctly this is not risky at all. But if there is a single line in the instructions you are not sure you understand, you are not quite ready.
There are quite a few tutorials on flashing in fastboot on this forum. Read them.
But generating your nvflash blobs you have to do without a safety net. It's worth it though! I have become much more adventurous with my tablet since I have the blobs squared away...

How do you define risk?
Flashing a bootloader (without having nvflash access) is always risky by my definition, it *can* permabrick your tablet if something goes wrong at the wrong moment. But it's the best we have.

Failed to flash stock image (maybe full bricked?)

Hi all,
Today I tried to flash an older version of the stock rom (v1.2.1) and thought I didn't need to flash userdata.img. That was a big mistake..
Now the tablet stuck at a bootloop. After that I thought I could simply flash twrp over the bootloader to peform a /cache & /data wipe so that I can fix the bootloop.
And now we come to the other BIG problem. I can't access the bootloader. It directly boots up the tablet with the Nvidia logo. Is there any solution to fix the tablet?
I tried at the bootloop to enter via adb into the bootloader but my PC isn't recognize my device (probably no usb debugging).
There is no way to rescue it? No apx drivers out there?
Your message seems to be unclear about one very important thing:
1. Are you able to successfully access the bootloader? I don't mean your custom recovery. I mean the black screen with very small font words with your serial and shows whether your bootloader is Locked or Unlocked.
From where I'm sitting, it looks like you flashed v1.2.1 without using "flash -w", as well as forgetting to flash ALL the stock img files. Next, it looks like you're expecting a direct boot into the bootloader, which is not possible. You need to hold down the Vol_down button and then hold the Power button until the screen comes on, THEN you need to let go of the Power BUT KEEP HOLDING the Vol_down. If done correctly, you should be at the bootloader.
From the bootloader, you will not be able to run adb commands. Instead, the bootloader takes "fastboot" commands. All this is assuming you've installed the latest nVidia Shield Family drivers from the nvidia gameworks download site.

Thanks for your answering. I flashed all .imgs, the blob file and the .dtb file . Everything but not the userdata.img. I can't access the bootloader with holding down the vol down + power button. I only can access the apx mode with power + vol up.

I notice in your sig that you do in fact seem to have a fully working new replacement tablet. That got me thinking along the following:
1. new tablet is fully functional, old one is not
2. both tablets have the same hardware spec
3. pull firmware from new one, and somehow get it onto the old one
4. hopefully old tablet should work!
The biggest problem is step 3... I only know of nvflash that might be able to help here, but I've never used it myself so I'm completely useless here. Maybe someone more knowledgeable could help out here, but otherwise it seems like you might be out of options.
If you do want to take a stab at nvflash yourself, THIS PAGE has a nice writeup of what some commands do, BUT BEWARE! It's not for our device, so don't just copy-paste commands! As long as you're not writing things to the new tablet, it couldn't hurt to try stuff, right?
It wish someone could help me with NvFlash because I have no knowledge with it.
So it's possible to make a copy of the system of my working tablet and flash it on my old tablet with NvFlash?
I hope someone helpful with NvFlash experience could help me out.
Btw I need to have an un-blob'd stock rom version to get it back alive? Afaik is there no public version.
NVflash is only useful if you have backed up using it BEFORE you brick it.

I have a replacement tablet. I could make a backup from it and use it with my bricked tablet. Do you know how this could work? (As I said I don't have experience with Nvflash yet.)

No the blobs are specific to the device.

Okay. So it seems that there is no way to rescue it. Btw is there no accessible bootloader in OTA 1.2.1 because I flashed the boot.img without any error and I don't understand why I can't access it.

Indeed - I was just talking about nvflash use in general. I haven't seen it used since tegra 3.
