Hey
I habe a Short question...
As we Do now have an unlock Tool... Does that give us Access to nvflash?
Do we now have nvflash in any way?
Sent from my HTC EVO 3D X515m using xda app-developers app
no, not now. But there is a solution for the prime, so hopefully it will come our way,too
Shouldnt wheelie theoretically also work for the tf300t?
Or the prime workaround? I mean isnt the 300 tegra 3, too?
Sent from my HTC EVO 3D X515m using xda app-developers app
NVFlash and Wheelie should work fine. The problem is that the method to use NVFlash requires a modded bootloader. There's a chance (possibly small; possibly large; either way, too much for me) you could brick your TF300 by flashing it. I would recommend waiting until someone comes up with a TF300-specific solution.
Well is there someone working on it?

No clue. AndroidRoot.mobi have a sentence at the bottom of the Prime guide saying that they're working on adding support for other devices. There aren't too many tablets that can use NVFlash (Tegra 3 required for this specific version of NVFlash), so besides the TF300 and TF700, what else is left? Acer Iconia A510 and A700? And considering that the Asus tablets will most likely have similar hardware to the Prime, I think the TF300 will just have to wait a short amount of time. I'm just as anxious as anyone else to see this happen.
Access to nvflash is the only thing stopping me unlocking my tf300. I want to wait until it is really difficult to brick.

You mean wheelie flashes an own bootloader in the background?

No. You can go to AndroidRoot.mobi and check the instructions. You have to flash the bootloader with fastboot. Then, wheelie will work to access nvflash commands.
Well you told me that it "might" work. So did someone already try it and your warning is just because flashing might fail due to for example a crash?
Or did you mean it might be incompatible at all?
I mean that since the Prime and TF300 are built similarly, there's a chance that the modded Prime bootloader would work for our tablets. There's a bigger chance that it would just brick our tablets. I only said "might" because it hasn't been tested, let alone proven, to work or not work. If you'd like to try the AndroidRoot.mobi method with the Prime bootloader, you're welcome to do so and report back whether or not it worked. But don't blame anyone if you brick your tablet instead.

As I do not really know the differences from programmatic side (probably other partition sizes and positions and so on) I do not want to try this method for now. The reason is that I to neighter know exactly how the bootloaders on tablets work, no what you have to look at before you can try this more or less safely.
This is the reason why I will wait and try to find out more.
Any updates on when nvflash will support our TF300's?
It looks like the guys that developed the nvflash unbrick process for the TF101 put the steps of how they did here:
http://androidroot.mobi/2011/06/13/nvflash-on-asus-transformer/
I wonder if someone with a bootable TF300 would be able to extract the info needed for the TF300? It looks like the same process should work for the TF300, just with the change of the partition table configuration, etc.

For the TF300T you also need the secure boot key. I'm not sure how they got nvflash for the TF201, but AFAIK the only way you can get the SBK is from Asus.
so basically what your saying is we're ****ed

Well not exactly, I'm only saying that (hard) work getting the partition table and such won't do it alone. We also need another shot of the luck or whatever else it took for the TF201 SBK to be disclosed. But since it was possible for the TF201 it should be possibe for the TF300.

I just got my transformer yesterday, only to realize that the new B70 model doesn't have an official method for rooting. I realize the new model has a different SBK, but there has to be a way to root without the need of nvflash. The Moto Atrix was rooted before we had an unlocked bootloader, so I don't see why the transformer can't be.
Basically what I'm asking is this: are there any developers working with a B70 model now? Or do they all have earlier models and don't have the ability to dev for the B70?

im looking for one too since i just got mine a few days ago as well... words were said about using a different root method instead of Nvflash... i hope one comes out soon
This method does not utilize nvflash, only it's based on a previous hc version.

I actually tried this method, I left gingerbreak running for a good 15 minutes before I gave up. That's the first time gingerbreak hadn't worked for me, it took a good 5 minutes on my atrix. The version I had on the atrix was an actual apk that you install on your phone though.... Something like that for the transformer would be awesome.

The vold exploit used in gingerbreak was fixed in one of the early 3.0 builds. It won't work on newer firmware.
Have you checked that your B70 is really locked?
I have one of those B70 that isn't locked.
There is an easy way to test if your B70 is locked with new key, just follow this post:
http://forum.xda-developers.com/showpost.php?p=16356361&postcount=50
I have not checked if my bootloader is locked, I'll do that when I get home tonight. Thanks for the reference there, I never found that thread after lots of searching. All I want is root for some of my apps and perhaps I over clock stock 3.2 if that is available.
Question though, what if nvflash rejects the test command referenced in that thread? No harmful damage to the device, I hope?

It only tries to open communication with your Transformer (and if there is new key in bootloader, it should error out here allready) and read few files from it. Of course, there is allways chance of something going horribly wrong, nobody can give you 100% correct solution.
My TF was sent today and hopefully might get it tomorrow, or wednesday the latest and will run that test then
That's awesome! I'm a little paranoid about guinea pigging that test so any feed back on it would be wonderful. For now I'll just enjoy the tablet in its natural form haha... Which is still pretty awesome.

I'll do that when I get home this evening then. I'll have to look up what command to use to do a backup. So if I can do a backup then its pretty much positive that I can do the nvflash root method?

Yeah, they're starting to show up, no real pattern to it yet that I can see.
So I was able to root my B70 after using brk's Root Method; everything ran smoothly.
I installed CWM recovery, but I have yet to figure out how to boot into it, Rom Manager doesn't work for rebooting into it for whatever reason
I am content with being rooted for now though. And especially content that I didn't get one of the B70s with a new SBK.
Here is a link to the root method I followed if you haven't already seen it.
http://forum.xda-developers.com/showthread.php?t=1185104
Rooted my B70 with brk's method as well, got lucky I guess. Everything worked fine after. This is a US model ordered from Amazon last week, if anyone is wondering.
tf101g build in july have new key in bootloader. b70 is mount how build, so 7 is july. I can't root TF in any way
Bought a B70 the other day. Got lucky bootloader was not locked.
Rooted within 5 minutes.
Got a B70 (Europe/WW) about week ago and rooted it just fine. I haven't tried to install cwm just yet, though.

Root how? If you root you can use nvflash, but new bootloader don't send command to nvflash
Is there a method for rooting the tf101 B80 yet? I've been searching for a while but only find old methods.

If it's rootable, I would know, as I've been keeping up on Team RayDroid's blog posts. Last I heard, they are looking for an SBKv2 device that can go into APX mode. Never heard any more news after that.
Sent from Sukia, my rooted HTC Inspire.
I think whoever comes out with a root method should hold of on releasing the method until after the first batch of Primes show up because we dont want them to block the method going forward too soon.
I have my B70 rooted using Brk's root toolkit. It can use nvflash to root your device, if unable to enter apx mode. It can also flash roms too. Check it out, it might work for your pad, it's worth a try. It can't brick your pad and it only takes a couple minutes.

Some of the B70 models are rootable, B70KAS1 and below should be rootable, B70KAS2 and above aren't. At least that's what I've got from reading all the threads about it.
I've completely given up on getting a root for SBKv2. If it hasn't happened by now....yeah. With the Transformer 2 hitting the shelves soon...the possibilities dwindle even further. I appreciate their effort, just don't think it's gonna happen. Shame on ASUS.
is such a thing possible at all with the tf700? i'm hesitant to root/unlock/flash roms until there is an unbrickable option out...
NVFlash works fine - it doesn't matter what version of Android your tablet is currently on. The only pre-requisite is that you have saved your TF700 "blobs" while you were on the .26 firmware or earlier. Once you have the saved the files, NVFlash will *always* work, regardless of the Android version.
If you've already upgraded to .30 or JB *before* saving your blobs with NVFlash, then you are stuck, there is currently no way to obtain the "blobs" needed to use NVFlash if you are past the .26 firmware before saving your blobs.
Hope that makes sense...

I am kind of a newbie so excuse my lack of knowledge. Is it possible to use the nvflash backups from another Tf700 to restore a possible bricked one?

NO, the nvflash backup is for your device only.
I wonder whether the guys from Asus service use nvflash to rewrite everything in case the bootloader gets messed up as many users did with TWRP 2.2.2.0 or CWM 6.0.1.3?
I read somewhere in the forums that they actually have to replace the entire motherboard in this kind of a situation. Any truth to this?
Yep. All hard bricks with the TF201 got new main boards. No one can unlock either after they get their tablets back from RMA after this. There's a big thread about not being able to unlock on the prime forum.

So let me get this right...if the motherboard is changed than you can no longer unlock the device and port other OSs? Are they putting in a superboard of some sort that cannot be unlocked?
I find this hard to believe especially when you can get the unlocking tool from the Asus website. At least let's hope it's not like this, otherwise my tablet would lose some of its appeal.

No, but the problem is that after a motherboard exchange, the CPU ID doesn't match the serial number anymore. The unlock tool must contact ASUS to get the unlocking token (unique for each motherboard), and it fails if the CPU ID doesn't match in their database anymore. It simply can't get the right token anymore.
Ok....this makes a lot of sense actually. Let's see if the same thing applies to TF700. I'll keep you posted to whether I'll be able to unlock my tablet once it gets returned.
I've looked around but I can't find the answer. What is NVflash? And what is it used for?
"Nvflash for TF700 is now among us!
This release allows unlocked devices to create a set of device-specific files that lets you access nvflash.
Once the procedure is done, you will always be able to recover any software brick (even bootloader!) as long as you keep your files safe!"
From the official thread: http://forum.xda-developers.com/showthread.php?t=1901479
It's a fail-safe. A way to back up your tablet in case you find yourself bricked.

In short, NVflash backup your bootloader for ICS version .26 only (not going to work if you on version .30 or JB and you only could install NVflash while you on .26 version, once you upgraded, it's too late to use this tool). This Nvflash backup tool will help you to recovery incase if you bricked your device.

NVFlash is a tool by NVIDIA that allows device makers and hardware developers to interact (read/write/erase) with the storage connected to the Tegra chip on a low level from a connected PC.
For us users, it is possible to use NVFlash with the TF700 only together with the "wheelie" tool created by some very talented hackers, and a backup of device-specific information that can be only obtained if the device has not been upgraded past firmware 9.4.5.26. For details about that see the thread linked by Godswrath.

NVflash works below the Android level and is therefore version independent. If you mean a way to get the files required to use it, there is currently no sign of a solution for the JB bootloader. Apparently even "unlocked" devices now require newly flashed bootloaders to be signed by Asus, so one cannot install the hacked AndroidRoot bootloader anymore.
Can it be used to fix a hard brick too?

Of course it won't fix broken hardware.
It can fix every brick situation that is the result of incorrect contents of the internal eMMC. You can backup and restore the Tegra boot config table, the bootloader, partition table, kernels, recoveries, and all other partitions. As long as you can turn it on and activate the NVidia recovery mode holding down volume-up, which shows up as NVIDIA APX device on the connected PC under Windows, AND you have obtained the needed files *beforehand*, NVFlash can fix it.

No way for you to gain NvFlash access, sorry.Only devices with 9.4.5.26 or lower firmware are eligible for NvFlash (you can't downgrade to 9.4.5.26, only to 9.4.5.30).

Its the former. In the 9.4.5.30 and above bootloaders, Asus locked it. Meaning when you "unlock" you are really only unlocking recovery and fastboot but the bootloader remains locked and signed with a cryptographic key. It prevents any previous Asus bootloader and any non-OEM bootloader from ever being loaded again. So far, there has been no success at circumventing (hacking) the locked bootloader and its not looking promising. There is a petition out for NVFlash asking Asus to allow wheelie to prevent bricking but I doubt if that goes anywhere.
The next best thing is @_that as you've already experienced. He is a human recovery. They have a 95+% fix rate for Transformer soft bricks here at XDA.
