In order to install this, you have to flash a recovery with the install script. So, Yes, your bootloader must be unlocked before doing NvFlash.

Ok who is is going to be kind enough to answer if this works with the TG?

Flash Back Original Bootloader ?

So can I just leave the AndroidRoot Bootloader and go to CM11, or do I need to return to the original 4.2.1 bootloader ?

I'm new to rooting the TF300 (it seems like you usually don't mess with the BL). I haven't seen the stand-alone original bootloader posted. Do I have to reinstall the Asus update to get the bootloader back ?

Thanks.
[Transformer TF300T Android Development] lj50036:
Bootloader

I would highly recommend going to the 4.2.1 asus bootloader. I can not say if the Android-Root bootloader works or not, but I would not chance it...

I also would just flash the stock asus blob from there website and would than just start over flash 4.4 compatible recovery though fastboot and than flash cm-11.0 from new recovery...Let me know if this helps and if you need any help with any of this drop me a line.. As always thx lj
[Transformer TF300T Android Development] david31262:
Thanks for the quick response, I'll do that. Is it correct that I can reflash and ASUS blob from either recovery or fastboot ?

(Blob is new for me, never herd the term in the HTC or Nexus worlds).
[Transformer TF300T Android Development] lj50036:
Bootloader

Fastboot is how you flash stock firmware from asus.. Make sure you get the correct one for your 300 WW or US or whatever SKU your tablet is

unzip the file twice you will see a blob file than put it with you fastboot file and boot your tablet into fastboot connect to PC and type

fastboot -i 0x0B05 flash system blob

once done type

fastboot -i 0x0B05 reboot

This will flash everything back to stock.. it will still be unlocked...

Boot fully into stock rom..

Than you will be ready to install 4.4 compatible recovery....

Let me know if I can help with anything else..As always thx lj

What is your PC's OS????
[Transformer TF300T Android Development] david31262:
Thanks. I keep a 32 bit Win 7 partition on my computer just for this kind of stuff (it seems to be less troublesome then Win 8.1/64). I also have Ubuntu around if I need it.

To date, I've used flashboot to unlock, but only loaded the system through CWM/TWRP.

I assumed I could also flash from fastboot, but never had the need. This may be especially useful if I ever get in trouble with the Nexus 5 (which, sadly doesn't have a Memory Slot).

Thanks to cmendon2 for writing the guide thread. It's a little easier to walk through then the original mobi site (though certainly many thanks to mobi too).

I'm finished getting the recovery blobs. Will let the battery top off, then will reflash the ASUS orig, TWRP, & CM11 (which I can Nandroid restore).

Only place I wasn't sure what to do was exiting the APX interface "nvflash --resume --go" didn't seem to do anything. I did a quick search to get "Hold the Power Button" for 6 secs to reboot.
[Transformer TF300T Android Development] lj50036:
Yeah that's what I have had to do in the past... I still ran the command before long holding the power button until the tablet vibrates...Let me know if there is anything else you need help with...THx as always lj

FYI Any Linux Is better than Window... I now a huge fan of Ubuntu.. I prefer Mint , but that's just me....

Got Stuck on the ASUS Boot Screen

Just to close the loop on this, after flashing back to the ASUS OEM blob, on reboot, I got stuck on the ASUS logo.

I had to follow Method 2 in this thread to get out of it:

http://xdaforums.com/showthread.php?t=2195883

So, either the fastboot staging option or TWRP "wipe" is needed. Perhaps an erase from fastboot could get there too.
[Transformer TF300T Android Development] lj50036:
Look in my signature you will see the nvflash unbrick TF700T GO TO THIS ONE... I know you have a 300 its all the same as long as your blob is for a 300..... Skip the nvflash stuff and start with the fastboot commands do them in order and read the stuff between the commands... Omit sudo if you are in windows.....

About at the end of my rope on this one (you know my story, lj50036 *sigh*).

Ran the ICS version of nvflash (I realize this is for flatline, but like said, I'm at hitting brick walls on what more to do). What

can I do with these backups to get my tablet back to original?? Is my only option to run process using Mint as outlined in your

signature, lj500356?

http://xdaforums.com/showthread.php?t=2590450

Spent so much time already, not sure if I have that many more hours available to get Mint up and running, etc...

My tablet's a tf300t, unlocked, rooted, running v9.4.3.30 (though bootloader appears to be the original from AndroidRoot

nvflashing - showing WW_epad rather than US_epad SKU). Still able to boot up via APX mode, but lost fastboot, boot up

menu, boots into APX mode automatically, and overall is acting flaky.

Also starting to wonder if it's hardware more than a software issue. So last attempts before throwing in the towel...Thanks for any

nvflash magic suggestions, or I guess...tips w/getting Mint up and running quickly *sigh*!

[Transformer TF300T Android Development] skorpios1027:
Despite my status of Junior Member, I'm not new to XDA and flashing, I just don't post much. I've been reading and searching for the last 4+ hours and haven't found the answer I am looking for. I recently repaired an old TF300T (Broken LCD and Digitizer) and it is unlocked on ICS (9.4.3.30 BL). I would like to use this process to safeguard this tablet, however when I go to download the NVFLASH and TF300T images from the ICS guide, I get the error that the files are outdated and to get the files from the Flatline guide. My question is if I use this process, will I be able to remain on ICS or will I have to update to JB (the eventual plan is to update so this will determine the timing)?
[Transformer TF300T Android Development] Clamor:
If the further plan includes update to JB than it would be better to make NvFlash allready on JB. Nevertheless, if you want to make it on ICS, PM me, I'll give you all needed tools.
[Transformer TF300T Android Development] skorpios1027:
Thanks Clamor. If it was my tablet, I'd just go ahead and update then make the NVFlash files. However, it belongs to my better half and she is resistant to upgrading. It took me 4 months to convince her to let me even repair the broken LCD/Digitizer even though I'm a professional electronics repair technician. Only when the digitizer stopped responding to her touches did she even consider the repair.

Hello Everyone!

SOrry about this, I've been searching and reading for hours only to run into dead ends.

I'm trying to root my factory TF300T, it was my wifes but she has a new ipad now and doesn't use this ASUS so it comes back to it's rightful owner. ha! So i've wiped it clean and it has since updated to 4.2.1 and build 10.6.1.27.5-20130902.

My question is, am I in the right thread to root this thing. I've noticed many of these threads are several years old and some of the links are dead, images are missing. Can anyone point me in the right direction? Where do i start? I think i need to unlock it first??? IDK. Any help is greatly appreciated!
[Transformer TF300T Android Development] Duckman5:
Totally wrong thread. This is for nvflash which lets you recover from a really bad flash. Anyway, yeah...unlock it (official ASUS app) , install the Kang TWRP from this forum, and flash a SuperSU zip and you're good to go.

i tried with WinXP as well as Win 8.1 …
[Transformer TF300T Android Development] ebonit:
First of all disconnect the device from your PC. Charge the battery 100%. Then try again to boot the device into fastboot mode by starting Power on and Volume down together. At the left corner above appears a line "Starting Fastboot USB download protocoll". In the middle of the screen 3 icons will appear. The first icon, RCK, is blinking. Pushing Vol up should open your recovery. Hopefully it is Kang TWRP! If yes, you may restore your last backup.

PS:

On the other hand If you can boot into fastboot, everything is fine. To get further you need "Minimal ADB and Fastboot" and the "Universal_Naked_Driver_0.73"

However if you cannot boot into either fastboot or recovery the tablet is bricked for good. I'm sorry! Motherboard replace is the only possibility to keep the device alive.

The AndroidRoot.Mobi Team is proud to present Flatline: Nvflash for TF700 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.

CONFIRMED WORKING

! make sure you follow the instructions like your performing heart surgery and you should be fine. (they have made it a lot easier then the ICS method!) and Make 6+ copies of the recommend backups :)

NOTE: I done it from CROMI-X 5.0.3 which i believe uses 10.6.1.14.10 bootloader. But it should work on any JB bootloader(But dont hold me too it :p).

btw did you try "adb pull /data/media/AndroidRoot"? thats what i used..
[Asus Transformer TF700] laod:
It doesn't show anything. Do i have to reboot the tablet back into fastboot mode?

Yes i tried "adb pull /data/media/AndroidRoot"
[Asus Transformer TF700] JoinTheRealms:
Well you most likely dont have an adb driver installed the tf700 universel naked driver contains adb/ fastboot and apx drivers but you have to install them individually. check device manager and manually update the apx driver if its got the yellow triangle. You will have to do the same when you boot into apx mode.

At that point you can probably reboot into android (again im not responsible for any mishaps :)) and copy the files over via mtp as you need the blob.bin file stored in /data/media/AndroidRoot to bootstrap nvflash.
[Asus Transformer TF700] laod:
Im using ubuntu not windows. If they are just stored on the internal memory then I'll reboot and copy them over to an sd card.

You need to download this http://download.androidroot.mobi/nvflash-tools-linux.tar.bz2 and cd into the extracted directory and run that above command to use the wheelie binary.

Make sure the blob.bin you previously generated is in that directory also.

[Asus Transformer TF700] rayman:
Unfortunately, that error message isn't the best in the world. I'll try and get around to adding a FAQ to cover issues like this...

What it means is that wheelie doesn't have the rights to access the NVflash mode. It can fixed by adding Vendor 0955 to a file similar to '51-android.rules" similar to getting adb working as non-root.

Alternatively, if you run wheelie and nvflash as root it will work. We'll provide a better explanation later.
[Asus Transformer TF700] laod:
Thank you for the explanation. It is all working just fine now :)

Alert: Possible stupid question. Now that I'm all nvflash set... I can reflash TWRP and the newest bootloader. Then if I brick, do I have to reflash the custom recovery and bootloader?
[Asus Transformer TF700] _that:
You just need to boot in APX mode (this will always work as long as the hardware isn't broken) and use wheelie with your blob. Then you can use nvflash to restore stuff.
[Asus Transformer TF700] faustus1005:
Ok, so I got as far as making copies via nvflash of the various *.img files. However, even though the commands ran

and appeared to be successful I don't see any of the imgs (bricksafe, etc). Where would they be located? I am assuming

in the same directory as the nvflash executable, but perhaps I'm wrong? I DO have the blobs though.

Also, after rebooting my device when I "finished" the process my device is no longer recognized by windows. No adb, fastboot,

apx, or mtp via windows. I used the universal drivers, and obviously since I made it through the whole process they were working,

but I can't seem to access my tablet from windows anymore. I tried to uninstall the drivers and reinstall them again, but regardless

of how I approach the matter now it tells me the drivers are incompatible.

Any help on either problem would be much appreciated.
[Asus Transformer TF700] JoinTheRealms:
Yip you can reflash twrp theres no requirement on the recovery for nvflash, I Believe once the custom bootloader had been fllashed, you can change bootloaders at your will and wheelie will still work;) easiest way to recover from a brick with nvflash is to reflash the stock firmware.
[Asus Transformer TF700] Frostbiter:
I just want to make sure before I do this. Even though I'm on the 10.6.1.14.10 bootloader I'll still be able to do this? I can flash the special bootloader without an issue?

It should fine as long as its a JB bootloader
[Asus Transformer TF700] workdowg:
Yes. I was on the newest and CROMI 5.0.3

Thank you very much, just wanted to make sure before I go about doing this.
[Asus Transformer TF700] faustus1005:
Oddly, I found the img files under Appdata\local\VirtualStore. The drivers, however, are not a driver signing problem. As I said, they previously worked and now do not. I have already disabled driver signing enforcement previously. When I attempt to reinstall them it tells me there is no compatible device connected. I'm starting to wonder if my cable might not be going bad on me since occasionally I plug the tablet in and it works fine. I guess I will have to pickup another cable to test with.
