Noob question but I want to be sure before I try this (I am assuming that all fastboot commands are done via Windows when the tablet is connected):

What do I need to type in place of the $ symbol?

Thanks!

Can you have root and a rom and still do this? Or stock unlocked?

$ ist from the Linux bash in Windows you just don't have it as you should have admin priviledges.
In Linux $ = normal user mode # = superuser/admin

@ Swaser18t
should be possible when you have saved it.

The magic about nvflash is: you can backup all sectors which are important and you can recover them independently if fastboot is working or not. so no matter why your tablet is bricked, you can always restore a status from which you have fastboot access as nvflash comes together with the nvidia chipset... :)

I would donate to, but unfortunately I don't have paypal or sth like that :(
But would be very, very nice if NVFlash would come for JB Bootloader :laugh:

On a TF300, "$ wheelie --blob blob.bin" gets me this result -> "[-] Failed to open blob file: blob.bin" Any thoughts? Dont think i rebooted into nvflash mode because screen wasn't blank. Little direction would be appreciated.

Okay on to the next question! Got APX to work in windows and ran "wheelie --blob blob.bin." Now says "Done - your device should no be ready for nvflash." TF300 says "Entering NvFlash recovery mode / Nv3P Server, Chip UID, !!!! device update sucess!!!!" Tried to run "nvflash --resume --rawdeviceread 0 2944 bricksafe.img" but now I get " 'nvflash' is not recognized as an internal or external command, operable program or batch file." Get same results with all commands that start with "nvflash." What am I doing wrong?

You're on Linux right?
Make sure you are in the directory where nvflash is and try typing "./nvflash" instead of "nvflash" alone.

    After a hard day of extra testing, we're proud to announce Nvflash for TF300.

    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!

    NOTE:
    • THIS REQUIRES A NON-BRICKED AND UNLOCKED DEVICE. IT WON'T WORK ON ALREADY BRICKED DEVICES
    • THIS ONLY WORKS IF YOU HAVE A PRE-JB BOOTLOADER


    More details at http://androidroot.mobi/?p=480

    Important note: License: Due to the nature of wheelie and the importance of people always using the latest version, Wheelie is NOT redistributable! You are allowed to download it and use it, but you are not allowed to redistribute it in any way - this means no GUI's including it, no reposting zips/tar.gz's and similar! At a later date, we will be releasing our source code and relicense it as GPL.

    Enjoy

    Seems like no one have noticed - the is a nvflash now for TF300T with JB :D https://www.androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/ works great - it tested it already. If you got any problems with blob.bin reflash the bootloader twice and regenerate the whille files.

    Nice, I'll have to give this try. Its good to have a safety net.
    So once I have generated the files and have NvFlash working, would I be able to then flash the new JB from Asus and then use the NvFlash files to go back to ICS bootloader?

    PS: This thread should be pinned.

    Yes! Once you have these files, you can move back and forth between any rom/bootloader you desire. ASUS can do nothing to prevent it once you have the files for your device!
    It also essentially makes your device brick proof (assuming you carefully follow our guide and do the backups!), so development gets a lot more safe :)

    would love to have this as a fallback, but I think I am in a rather interesting predicament...

    See, I don't think I ever backed up stock ANYTHING on this tablet, and I don't even remember how I got a rom on this thing to begin with (alot of life crap going on I think). All that I DO KNOW is that I am currently running CM10 and TWRP, and obviously have an unlocked bootloader.

    Some peeps say that if you are on JB, you can't go back to ICS, but I seemed to have no problems with TWRP by going to hyrdo's ICS rom from cm10... maybe there was something I was missing.

    I guess I just need someone to give me some TLC and guide me in the right direction. I know warranty is voided... So poopy there. If I need to do this as a Q&A entry, I will, but forgive me for checking here first as I know that sometimes people post things where they don't belong.

    I am thinking it would be best to return this bad boy as close to stock as I can (kernel, rom) and then try the NVflash from there. But I don't have a stock ICS rom other than "V9.4.3.30 Only for US SKU (Android 4.0.3)" (not sure if this is a good starting point or not...

    Everything personal is backed up, so any direction would be helpful :D

    If you are unlocked and and running CM10 it sounds like you never updated to the official OTA JB rom from Asus. If that is the case then you deffinitley have the ICS bootloader. Also if you are running CM10 right now you cannot be on the JB bootloader as CM10 doesn't work with the new bootloader.

    I am pretty sure you can use nvflash to back up all the important files from any rom as long as you are using ICS bootloader, which it sounds like you are.
