The AndroidRoot.Mobi Team is proud to present Flatline: Nvflash for TF300T Jellybean!

This release allows generating nvflash blobs for your specific device, making your device unbrickable as long as you have a copy of the blobs.
As a brand new feature, it will also enable wifi and upload a copy of the blob to androidroot's server. Later, a solution will be released to retrieve the blobs from the server if you ever loose them.

So, having read the guide thoroughly, if already on the JB bootloader (10.4.20.0), is it necessary to update to the latest firmwares before running this or can I do it on 10.4.20.0? I note that the guide references bootloader 10.6.1.15.3. Also, anyone know whether doing the NVFlash thing wipes the user data?

Thanks in advance. Looking forward to running this on my TF300T once I get my ducks in line.

@rayman Is it working with the bootloader for the latest update (10.6.1.27.5 )? Or should we downgrade to 10.6.1.15.3 to be safe?

It is working in 10.6.1.27.5 bl....im on c rom
i have a question....what files should i save?
the files that was generated only have 11mb...normal?
once i get the files can a reflash the twrp recovery?
if i brick my tablet what should i do with this files?
tks in advance :)

This is really exciting! Thanks devs!

Just to confirm and clarify (for noobs not unlike myself), this does work with the 4.2 BL (Rom example being CM 4.3 nightlies).

So I'm a bit confused. This process involved installing a new recovery image. If my device already has TWRP custom recovery and CM10.1 nightly, would I just follow all the steps listed and then reinstall TWRP as a final step? I was concerned with the steps that involved rebooting the device and wasn't sure how that recovery image would handle CM10.1

OK I just did it and I got a 1.6 MB blob file...I did the wheelie and it worked but where were the files: Unlocked token, factory config, and bricksafe img files received too? They were not in the nvflash directory nor on the device, but it said all three of them had been received succesfully.


Edit:

Found them. Located at: User\AppData\Local\VirtualStore
All three were there :)

I'd like to know this too. I think we can reinstall TWRP -42 at the end, but I'd like some confirmation by someone more knowledgeable than myself.

Yes, you can install whatever recovery you want after getting your blobs.
You are also free to install whatever bootloader you want afterwards.

The recovery is essentially CWM with some extras, so it should flash any CWM flashable rom without issue.

It works on all currently released bootloaders. If we hear of asus fixing it in a new bootloader, we will put a latest bootloader supported notice on the guide on the website.

Only unlocking the device wipes the user data. Doing the NVFlash thing doesn't wipe anything.
