There seems to be some confusion about NVflash and just how powerful of a tool it is. Like others have stated it has the ability to recover a bricked device, including a corrupt bootloader. Many on these forums may not have the technical knowledge to understand what a bootloader, recovery, or fastboot is exactly.... So to put it in lamens terms it is free insurance for you tablet. Pretty much anything short of hardware damage can be recovered with NVFlash. So if you make a mistake while updating your device or testing a new build and have exhausted every other method of recovery, NVFlash is there to get your tab up and running again. The comment about this tool is only needed for noobs is far from the truth. If you unlocked your device and are still on .26 then you would be silly not to utilize this. Would you turn down free insurance for your car?.... Didn't think so. While I may never need to utilize my backup files, it provides me comfort knowing if something goes wrong during a flash or otherwise it is there to save my ass! :)

Thankyou so much devs for making this available for our device. Considering how much the infinity cost I will take every step possible to protect it.
[Asus Transformer TF700] W3ber:
I updated .30 2weeks before.:( Sometimes come handy nvflash.(maybe port to our build)

This. Lol can't wait for that brother, it's going to be epic

For me is was $277. too much for me so having them send it back and hopefully there will be another way to fix it.

Does anyone know if a tool might come along to unbrick already hard bricked devices using NVflash now that its out for the tf700?
[Asus Transformer TF700] lenny.chem.dat:
Hehe, that's cute. We have guys in this thread calling people noobs as they find an additional backup method?

In my opinion, any rescue for a >600$ device is worth mentioning.

In the old days of android 1.6, devices were bricked simply by applying a faulty CWM backup. And that happened a quite many times. So all pros out there be happy that you can rely on CWM so much...

As long as you did not update the bootloader, you should be able to use it.

I was on bootloader .26, running Baked Beans 4 ROM when I ran NVFlash. Worked great as long as you follow the directions.
[Asus Transformer TF700] cyiam40:
Restore .26 Bootloader?

I have a complete (Including Boot option) TWRP stock backup of .26. Can I restore that complete backup and get the .26 Bootloader back?
[Asus Transformer TF700] lafester:
If you could it would be in the op and posted 100 times throughout the forum :)
[Asus Transformer TF700] urrlyx:
The boot backup is a backup of the boot (kernel) partition. It is not the bootloader.
[Asus Transformer TF700] ford12acing:
should i do this if i plan on flashing the new jellybean update (supposed to release this week i believe).
[Asus Transformer TF700] lafester:
Only if you plan on unlocking.
[Asus Transformer TF700] THunDA:
From what I read it only works on windows atm, I successfully did it on windows 7 64bit.

May be a stupid question but your not on the newest .30 boot loader are you? and unlocked ?

It for sure works on Ubuntu. On running 12.04 and had no problems.
[Asus Transformer TF700] MartyHulskemper:
As I said, I'm OCD, pleading guilty. I'm on CM10, unclocked while .26 (haven't flashed either TF300 JB ROM or .30 stock(-based) ROMs). It's not a stupid question at all -- I did read the requirements -- actualy read and re-read the entire guide a few times, since I am acutely aware of the ramifications if anything goes wrong here -- but I know there are a lot of people that do not. ;)

Now I am going to bed. ;) Had a lot of other stuff to do. G'night!
[Asus Transformer TF700] THunDA:
Thought i read it somewhere, thanks for the correction.

Just figured I would ask, I'm not even close to being as knowledgeable as some on this board but I'm sure someone with more knowledge will chime in.

Good luck !

Hi, mate i would say that something is wrong with your drivers, try to uninstall your fastboot drivers while your device is connected to your PC in fastboot mode and manually install the drivers from the "naked drivers" pack.
[Asus Transformer TF700] MartyHulskemper:
I've done that several times, but I will give it another go. I am currently tryinh yet another USB port, might make a difference. Since I am on the x64 bit version of Windows 7, there's only an option to have the device show up in Device Manager, then uninstall from there, unplug/replug the 700, get it detected and install the drivers from the menu. I can't rightclick and install the driverset in advance, unfortunately -- that woudl have prevented some headache. OK, on we go. ;)

---------- Post added at 10:43 AM ---------- Previous post was at 10:35 AM ----------

W....T...................

I am totally speechless right now and staring to a device flashing the bootloader. I currently have no clue what I have done wrong, or well, in this try. Will do some bookkeeping in parallel.

I am pretty nervous regarding rebooting the device -- this is almost military-grade suspense. Hahaha! That does tell you something about the level of frustration, anticipation, whatever....

First steps have worked. Will report back in later -- thanks for the support!
[Asus Transformer TF700] Pretoriano80:
Well, first step was the only step where some bricking risk was involved, from now on just follow the guide and make sure you backup the files.
[Asus Transformer TF700] MartyHulskemper:
Roger, wilco. Or rather, haveco -- since I've finished... successfully, that is. ;)

I have few observations I'll post here in to the hope that somebody may benefit from my desk head-butting, other than a plastic surgeon. :)

1) Nitpicking mode activated: fastboot -i 0x0b05 reboot did not boot me into fastboot -- booted CM10 instead. Just did it manually, all good.

2) Copied to NAS in triplicate copies over FTP, then to local system, as MTP wouldn't work. Used MD5 Checker (Play Store) and MD5 Hash Checker to verify file hashes -- all went well. (Off-topic recommendation: the latter one can be called by the Send-to menu -- mightily convenient!)

3)I must admit I found it a bit confusing to have the guide refer to 'blobs' in the plural until I read the included log file and saw there were several included in the one 'blob.bin' file. Just another observation for other NvFlash n00bs like me.

4) Bootstrapping into wheelie reported a chip UID and device update success -- a moment of relief, since I had almost expected my dear old friend Murphy to come along and crap in my lap again. ;)

Apart from the points mentioned, EXCELLENT tool, EXCELLENT guide. Anyone should be able to do this. M'kay, in my mind, that remark immediately raises the question why the heck it took almost 6 hours of my life yesterday to do what I've done in not even 20 minutes including all booting, rebooting, blobbing, picking my nose and plucking my beard in between...

5) I un-/reinstalled the ADB/Fastboot driver many times yesterday, in all sequences and combinations I can think of. I did again earlier today, right before flashing. I do not think this was a driver issue, however, because...

6) I changed USB port as well. I tried several yesterday, so that might not be a real game-changer. But...

7) I removed the USB extension cable I almost always use and instead plugged the TF700 cable in directly. FWIW, my desk is deep and relatively inaccessible, so I tend to have that extension cable plugged in a back USB port so I do not have to use a front port (they have been so finicky I have actually disabled them altogether, although they are they only USB3.0 ports on my system). I think that was the defining point, since from then on, it went on without a hitch, essentially.

Thanks all for thinking along and keeping the suggestions coming -- I've had a good laugh on the discussion on the "n00bness" factor and usefulness of NvFlash -- my $0.02: you should set up as much backup and security measures while you can. In my last job, when the excrement impacts the ventilator, you could very well end up dead. In this case, luckily, it's the device taking the (virtual) bullet, but I'm not even sure that'd that much less painful. ;)

Thanks for the great tool and port -- it is really appreciated! :victory:
[Asus Transformer TF700] jtrosky:
It's called sleep, my friend! I can't count the number of times I was working on something for hours the day before (without success) and then figured it out in a matter of minutes the next morning! It's amazing how much a little rest and/or "starting fresh" can help a situation!

Glad to hear you got it working - it's a great "peace of mind" to have NVFlash in your back pocket!
[Asus Transformer TF700] MartyHulskemper:
Thanks, jtrosky! I was very close to clinical depression yesterday, but I indeed was very tired. That's status quo at the moment, with my job and two very young kids bugging me. ;) I'm glad I got it working, it's quite the insurance policy, albeit, as with all insurance policies, one you hope you will never need. :)
[Asus Transformer TF700] paddycr:
I know it is kind of early but has anyone tried this with the new JB bootloader? Yeah, I know it probably won't work but weirder things have happened. I would love to have NVFlash running for foolish people like me who upgraded to .30 but I hold out very little hope... :crying:
[Asus Transformer TF700] androidxen:
Urgh, I usually hate asking for help since I don't like clogging up threads with these kind of posts, but I've been stuck on accessing nvflash for the last hour.

I'm trying to use the command wheelie --blob blob.bin

1. I have installed the provided Universal Naked Driver.

2. I have accessed fastboot, used the following commands:

fastboot -i 0x0b05 flash staging ebtblob.bin

fastboot -i 0x0b05 reboot

(turned off device, turned back on to fastboot)

fastboot -i 0x0b05 boot nvfblobgen.img

(as noted on the guide, got an error, device rebooted;

found AndroidRoot folder in sdcard/, made two backups on it to my PC)

The wheelie command gives me this error:

Failed to open blob file: blob.bin

I made sure I didn't move the AndroidRoot folder, I copied it (that's a mistake I've done before...), don't see any steps I've skipped.

I am on Zeus' ROM, though he hasn't updated firmware to .30, it's still on .26)... am I supposed to flash stock first?
[Asus Transformer TF700] urrlyx:
None of the custom roms update the bootloader. You would not have been able to flash the custom bootloader at all if you were on .30.
[Asus Transformer TF700] paddycr:
I wasn't talking about custom roms. I am presuming (although not certain) that the bootloader gets updated with the JB OTA. Does the NVFlash process detailed here work after updating to JB via the OTA released by ASUS?
[Asus Transformer TF700] urrlyx:
And I wasn't replying to your post. Sorry, I should have quoted Androidxen but I was being lazy. :P
[Asus Transformer TF700] Carwin:
Copy blob.bin to your wheelie folder,.
[Asus Transformer TF700] josue85:
Did you copy the blob.bin file that you generated in the above step to the same folder that you have the fastboot.exe in? I had the same issue and realized I hadn't copied over the blob.bin file (the instructions kind of gloss over that step). Hope that helps.
[Asus Transformer TF700] androidxen:
Not in a place where I can access my tablet, but I definitely did not move the blob files. Thanks guys, will do that when I'm back home! :o
[Asus Transformer TF700] wolfman87:
About to run this today, just wanted to ask (since I started reading through the guide) after the last step ($ nvflash --resume --read 7 unlock-token.img) is there a proper way to reboot (option on screen, use power button, specific command, etc.).

I just don't want to get to that point, post something, and sit around waiting for an answer :)
[Asus Transformer TF700] rightonred:
Nvflash -r --go

Starts the tab normally. Although once everything is pulled and flashed it doesn't really matter how you reboot it.
[Asus Transformer TF700] wolfman87:
Cool, thanks! Hopefully all goes well tonight.
[Asus Transformer TF700] B-dub25:
Quick question. I reboot into where it states NvFlash recovery mode. The last step says to run command nvflash --resume --rawdeviceread 0 2944 bricksafe.img

When I do this I get bash : nvflash command not found... is there a certain way to use this command. I run fedora ( Linux). I did do all the steps up to this and it says it was successful.
[Asus Transformer TF700] brad0112358:
Now that Jelly Bean is out for the TF700, those of us with the bad timing to upgrade to .30 without realizing it upgraded the bootloader which we now realize prevents us from using NVFlash have a decision to make; Should we upgrade to stock JB which apparently includes yet another new bootloader, or should we avoid updating the bootloader in the hope that NVFlash might be made to work with .30 more easily than with the new JB bootloader?

rayman,

Any advice you can give potential developers like myself who saw the capabilities of NVFlash as the security needed to allow experimentation with dual boot and/or modified kernels?

Is there any reason to think that .30 might be made to work with NVFlash more easily than the bootloader that comes with JB?

Is NVFlash for the new bootloaders on the TF700 still being worked on? What is your gut feeling on the possibility to get things working with any of these bootloaders?

Thanks! And thanks for your contributions to the community thus far!

[Asus Transformer TF700] oo3:
Has anyone tried this on a Mac? I'm stuck at the wheelie part. I think the device is in APX mode because when I reboot while holding the volume up button, the screen is blank, but when run wheelie --blob blob.bin, it says "cannot execute binary file."

Thanks, I did a little researched and can confirm this as well on the TF Prime forums. Used Parallels to boot into Ubuntu and finished the job.
[Asus Transformer TF700] Chronos2187:
you probably forgot to download and extract the NVflash binaries zip. I did that at first too.
[Asus Transformer TF700] MartyHulskemper:
I would bet indeed this doesn't work on anything other than .26's bootloader, at least for now. It sucks you only find out issues like this after flashing an update -- and one that didn't provide any tangible advantage at that... :( I'm glad I went the custom ROM route beforehand, but that doesn't help you in any way -- I'm sory for you guys and girls.
[Asus Transformer TF700] Chronos2187:
If you get to the bricksafe.img part and nvflash hangs similar to below, try using a different usb port and it should work.
[Asus Transformer TF700] adrenalinh12890:
Help. missing files :confused:

I successfully ran:

[Asus Transformer TF700] Darksurf:
The images should be in the same folder you unzipped the nvflash binary.

Yea. I got it. thanks.

I had to extract the files somewhere else. Originally, it was in the "platform-tool" folder under SDK. I wasnt able to get the img files to copy because im guessing, it needs admin permission? I located the extracted files else where and now it worked. I finally have it now.:victory:
[Asus Transformer TF700] jimbob_sf:
I started on 26 and had no problems getting nvflash backup. When it booted, I'd see something like android mobi and a firmware version in the upper left corner of the screen. I applied the USA JB update and now when it boots, it only says "The device is unlocked". Is this expected?
[Asus Transformer TF700] urrlyx:
Yes. Every firmware release from ASUS has included an updated bootloader to go along with it, so anytime you flash one you'll be flashing the corresponding bootloader as well.

Are you on the .26 firmware? If you are on ICS .30 or Jelly Bean, you are out of luck - you cannot use NVFlash unless you are currently on .26 or earlier.

[Asus Transformer TF700] Droid_X_Fan:
I followed the directions and have all my backup files saved in multiple locations. I'm about to install a JB ROM, but I'm not too familar with nvflash. I'm guessing that if I install a JB ROM (replacing my current androidmobi bootloader (?)) and later need to get into nvflash...I could still do that using the backup files. Or, is nvflash always available on the tablet?

I'm used to flashing roms on my phone and on the Infinity prior to JB...some of this is a little different to me now.

Thanks in advance!
[Asus Transformer TF700] urrlyx:
APX mode is always available. The thing the androidmobi bootloader lets you do is create the backups. You can always use them, but only with your device.

Procedure for bricked TF700 ?

Hello everybody,

Thanks to the author for this well-explained tutorial that I followed, allowing me to backup those precious files. I didn't know I would need them that fast though...

Does anyone know how to use them to recover the system ? I searched a lot and found few useful info. I'm so desperate that I'm even about to call the Asus support... :D My tablet keeps booting on and on until battery dies, I can't even shut it off. I only have access to APX mode, but when I use the wheelie --blob blob.bin command, my ms-dos prompt stays blocked at the line that says Sending file : 100%. And I can't to anything else. If I ctrl-C to take control again, the tablet leaves APX mode.

If somebody has a lead to solve this, I would highly appreciate it.

Thanks !
[Asus Transformer TF700] Mike3.14159:
1.Also wondering what the procedure for restoring is?? Ran through the setup fairly quick, had to play with the drivers a bit but got it to work after a few attempts, but whats the commands and order if pushing the backups back on the device??

2.This has sort of been answered but if I manually update to the JB firmware its my understanding that I will not have the Androidroot bootloader, entirely expected, but my device will remain unlocked as it was before and I will still be able to go into APX mode???

[Asus Transformer TF700] stanglifemike:
So do you keep the Androidroot bootloader when updating to JB or not? I have denied all updates and about to do nvflash on mine. Just wondering if I shouldn't bother if JB replaces it. Thanks
[Asus Transformer TF700] jtrosky:
Does *anyone* know how to actually use the saved NVFlash files to fully restore a bricked tablet?? It great that we've saved these files, but I have no idea how to actually un-brick a bricked tablet using them! :)

I did manage to figure out how to use it to flash a custom recovery at one point when I did something stupid, but even this took about an hour of searching and trial-and-error, just to do this:

wheelie --blob blob.bin

nvflash --resume --download 5 openrecovery-twrp-2.2.2.3-tf770t.blob.SOS

(at this point, you should be able to boot into TWRP and flash a ROM)

This has helped me, but it sure would be nice to know exactly how to restore *everything* via NVFlash. Typically, with "native" NVFlash devices (where wheelie isn't needed), a "download.bat" file is usually provided that does everything you need it to in order to completely flash a bricked device to a fully-working state. That's where I'm trying to get to - so that we could just type "download" and have our devices restored.

Anyone?

Thanks!

i successfully flashed this before i upgraded to jellybean, now that android root (or whatever you call it) in the upper left corner is gone and it says device is unlocked. did i lose nvflash?

what are you talking about? you can't 'lose' nvflash.

I was under the impressions that nvflash wrote itself onto the bootloader? i thought that my jellybean update re-wrote itself onto the bootloader. I could be thoroughly mistaken however.

Yes .. the same problems in Windows 7 .. When installing the drivers ( or using update function ), use:

- Browse my computer for driver software

- Let me pick from a list of device drivers on my computer (not "browse disk/directory")
