[Q] Restoring the unlock token with nvflash - Asus Transformer TF700

Hi, my tf700t recently broke . However, it was unlocked and asus still repaired it free of charge. It was a hardware issue. But they relocked it. I was wondering if it was possible to restore just my device's unlock token. I did a full back up with nvflash but I do not know how to restore anything. Thanks any help is appreciated.

Did you try with Asus unlock tool? It probably works just fine.

Tried it, it gives an error. I am pretty sure if can figure out how to restore the unlock token it will work. That being from the NvFlash back up.

I don‘t know much about NVFlash. I am very sure someone can chime in. Good luck.

Whoops, looks like its something about the CPU ID. Looks like I have to RMA it.... Again.

The nvflash blob files are tied to your original machine so there is 0% chance you can reuse them as they will not work.
However you can contact Asus about resetting your new serial number in their dB which then allows you to use the unlock tool again.

Root for TF101 S/N B70* .24

Hello,
A collegue here at work have a TF101 B70, and he told me he tried every available root methods with no success.
I told him to bring his Transformer, and we tried my method documented here:
http://forum.xda-developers.com/showthread.php?t=1704209
It worked !
Don't know if it will be usefull for anyone but I felt like I had to announce it.
Please report me if it works for you too, and which version of FW and S/N you have.
Thanks,

With nvflash being available for all TF101 devices, we will always have root, no matter what.

Doesn't the nvflash method unlock the device and void the warranty ?
No it doesn't, since the bootloader was cracked and not officially unlocked by ASUS, there's no real way for them to tell. It does no permanent change to your bootloader or APX mode. Nvflash for sbkv2 is in my signature, however, the Tf101G and slider have different bootkeys which have yet to be cracked. Those will have to continue to use exploits. My PERI tool currently works on all devices and firmware (and supposedly the next update) and is a one click root option. You can check it out in my signature.

No.
Rooting voids your warranty too, by the way.

Unlock Device Tool, anyone else getting impatient?

I had the loose screen problem with my 1st TF700. Got a replacement, but then I couldn't unlock it..
It has been allmost a month now, and it still persists.
Any of you know how long people waited the first time this occured?
Is this just because Asus is too lazy to update the program with the newer product serials?
Regards,
I just replaced my first TF700 with a new one and I didn't have any issues unlocking the new one, which is a C7 serial number.
What does your serial number start with? just curious if it really has to do with the newer/older serial number or not...

Hmm, wierd..
My S/N starts with C70K. Don't know if that's the new or old
I'm getting that same message too.. I wonder if emailing them would help
I had a Prime. Unlocked it. It had a screen issue. Got it repaired. Couldn't unlock again. Many, many folks (maybe the majority) with Primes who were repaired weren't ever able to unlock. Asus doesn't warrant the unlock tool or support it. Their attitude is, if it works, it works; if it doesn't, it doesn't.
Tien was very apologetic to me but not helpful at all.
What the.. So that means I need to get a 2nd replacement just to get unlocked?
That's just sad..
I'll try to send an email, and see what they have to say about this.
What a scam by Asus - release stock firmware that sucks and then void all warranties when you unlock in order to get a properly working tablet!
If the damn stock firmware worked correctly to begin with, we wouldn't have to unlock the bootloader in order to install a custom ROM!
Sorry - moment of frustration there!

I always install a custom ROM no matter how good the stock is. Even if the stock rom is PERFECT, I will still install a custom rom.

Someone posted that they had the same problem and complained loudly enough that their complaint was "elevated" to the next level, and then mysteriously, they were able to unlock.

Got a reply from ASUS today:

Why am I not able to unlock the bootloader of my device with the Unlock
Device Tool?
[ASUS]
Unlocking your eee-pad will cause side effects. It might make your eee-pad
unstabile, and it voids the warranty.
Therefore, we do not recommend to unlock the bootloader of your eee-pad.
But what is happening when you try to unlock the bootloader, any error
messages or so?

[ME]
I'm aware of that. But I rather want a device with a custom ROM I can use
normally before jellybean arrives, 'cause currently the stock ROM is very
dissapointing..
I attached an image showing the error I get.
Thanks for the reply!

Hi again
As long as you use the right unlock tool for this model, it should work.
Have you tried to first take a factory reset of the unit, before performing the unlock tool?

True that.
I didn't try the step with factory reset before unlocking again, 'cause I'm heading to the shop where I bought it to get it replaced..
2nd pad with loose screen, clicking sound, and this one also had light bleed.
Btw, have any of you noticed the .txt-file in the internal storage called "Unlock Time" or something? I opened the file, and it was written the date and time of my last unsuccessful unlocking-attempt Is this file created only if the unlocking fails?

No, i had that file after i successfully unlocked my device.
Bump. I'm getting a slightly different error message: "Failed to unlock your device. Please try again later." I tried for about a month with the last one I had, finally exchanged it a few days ago, and the new one is giving me the same message. The last one was in the C7 series, this one is C8.
Did anyone have any luck dealing with support?

Trouble opening Unlocker_V8

I am trying to install recovery and root the TF300T that I just got. It looked like I needed to start off by unlocking the bootloader. I downloaded the file from the Asus website (V8 unlocker) since it is running 4.2.1. However after trying to run the unlocker, I keep getting "There was trouble parsing the package" immediately upon opening the APK file. I have been able to install other APK's without a problem. I tried 2 different file managers, downloaded v8 unlocker from 2 different locations, tried downloading it directly to device as well as transferring from PC. Still no luck. Is there anyone that can assist with this? Thanks.

Im pretty sure there is a Windows Utility you can try to connect with the tablet over ADB to unlock.
That would make sense, but I've had trouble finding a utility to do so. I will look around a bit more, but there's nor eason I shouldn't be able to run that APK. The V7 one runs fine, but finishes with some unknown error.

Well it looks like I was able to get it rooted, but I still can't install another ROM because I can't unlock the frickin bootloader. The guide that I followed didn't mention having to unlock the bootloader before being able to install the TWRP recovery. I went ahead and follwoed the instructions to flash the TWRP recovery and now my recovery image is shot. I need an option other than the APK tool from Asus for unlocking the bootloader.

The unlocker-V7 worked on the latest jellybean without any issues. I had to contact asus after registering the device on their site. i included the SN and MAC address. I also included a link to the google search results for the issue so they know the extent of it. They did something on their end and V7 was able to run and unlock it. They got back to me the next business day as well.

I've actually been on the phone with them multiple times and I couldn't get it straight with them no matter what. Usually I would get a tech that was of no use and not very technical so I basically gave up and this was months ago.

Pretty sure I have tried both as soon as there was a post here about it but just to make sure I just downloaded 7 from the asus site right now and gave it a shot and sure enough i get a network error, try again, etc. I know they have duplicate MAC addresses on file for me and each and every time i asked them to update their site with my current MAC they talk about "im sorry...we cant support unlocking......it voids your warranty"........blah blah blah...... meanwhile they provide the tool. Go figure. That's why I just said F it I wont buy another Asus product again.

Bootloader is relocked and ASUS cannot help me

Hey folks,
hope you can give me any advise.
Unfortunately my TF700 got a corrupted Storage and nothing worked but fastboot.
I was finally able to flash stock rom via fastboot.
But now it seems the bootloader is locked, since i'm not able to flash a custom recovery.
On Boot there is a message that says: "no certificate to inject" an it boots into stock Android JB.
BUT: i want to flash a custom rom.
I already opened a call on ASUS but since 3 weeks they cannot solve the problem. The unlock tool always says that there is a network error, and does not unlock.
Thought it is not possible to relock the Bootloader, but it seems that i made it
Would be nice if anybody could help me with this.
Thx. _
I doubt very much that the bootloader is locked. Check on boot for the tiny text top left: The device is unlocked. It's not there??????
How do you try to flash a recovery?
Post your steps in detail and also check that it's a compatible recovery you are flashing.
While you're at it, also post your bootloader version.

I did some asking around and it would seem this can happen ..... :crying:
There have been cases where a larger android kernel can overflow the partition boundaries and wipe out the unlock token ...
This can also happen if a bad blob is flashed ......
Sorry for the bad news but if you dont have nvflash access and your unlock-token there is nothing that can be done .....
Thx Josh
Actually i flashed original latest blob from asus site via fastboot. And i think the bootloader was included.
But since i have no nvflash backup it seems i am lost in the locked boot loader.
Is there a way that ASUS could help me out?
Were there any cases where ASUS did help?
Thanks for your help

After that stock rcovery is still present
Today after 3 weeks i got finally feedback from ASUS....yeah.
They said: that in their systems my tablet is now set as a locked one and i can try to use the unlock again.
But when i tried that there is still the unknown network error appearing.
So the unlock is still not working evem when asus set it as locked in their systems.
Could it be, that there is something more in my tab which is at a wrong state?

After months stucking in a locked tablet with stock Firmware and all the lags while using it. The changes made by Google which forced asus to modify the unlock service let me now unlock the tab again....yeah.
Now i am back in business and already back to zombi pop with f2fs.
After a week oft using it i can confirm, that the tf700 has never been that responsive. Vera impressive rom with a great performance thanks for all your help.

I'm glad it worked out in the end.
My story is basically the same except I was advised to get an RMA and send the tablet to a service center. That is where the nightmare escalated. The service center said they did not help with unlocking, and they told me my tablet wouldn't boot and they would have to replace the motherboard (for $341).
When I wouldn't pay, they sent the tablet back. It booted just fine, and, suddenly the unlock tool worked. I wasn't aware of changes made by Google that you mention. I had to delete my Google account for the tool to finish.
Anyway, I too am happily running ZombiPop and am impressed with the performance.

HELP!!!!!! Locked bootloader after flashing a kernel and it doesn't want to boot

Hi guys
As you probably know by reading the title, i completely messed up. I was on the stock google factory image and decided to flash a custom kernel. I enabled usb debuging and oem unlock. after having unlocked the bootloader, I installed the twrp boot img and then flashed the kernel. All was well when i stupidly decided to lock my bootloader. Things crashed and now when i try to boot into my phone, the google logo appears and 1 seconds later crashes keeps doing it until i turn my phone off. My bootloader is locked and i think usb debuging and oem unlock are also disabled.
The same thing happens when i try to go to the recovery, it just crashes.
Any help would be greatly appreciated guys. thank you !!

I don't believe so since you're not the original owner. However, it doesn't hurt to try.
If you bl locked the phone w modified software ur boned. I believe that RMA availability is transferrable from owner to owner, however, I also believe that they will refuse to RMA a phone which technically broke because AVB is doing its job properly. You can try but I'd say your chances are slim. Sorry mate. Also future reference: if you don't have any reason in particular to relock your phone, just don't. You'll save yourself the hassle of having to do it again and it wiping the phone everytime any software thing goes wrong or anytime u want to upgrade custom ROM or kernel or anything of the sort. This goes for any phone not just those with android verified boot.
