[TOOL]TF201 NVFLash [Updated 21. July]

[fatdoggie]

Somehow, I messed up while attempting to flash CM11 and have gotten stuck on the Asus logo screen and cannot re-enter recovery. It doesn't show the "Device is UnLocked" as it normally did- it just hangs forever.

I can get into the APX mode, have the latest Naked Drivers loaded (tried on x64 and x32 Windows) and the device shows up in device manager. I have also tried using Linux and the device in AXP mode is shown in the lsusb output. I've tried this with multiple USB dock cables.

No matter what configuration I try, I have been unable to get wheelie to communicate - it always dumps out with an "Error 3" as below:

C:\nvflash>wheelie --blob blob.bin
Wheelie 0.1 - Preflight for nvflash.
Copyright (c) 2011-2012 androidroot.mobi
========================================

Waiting for device in APX mode...
[=] Chip UID: 0x15d0787bc641408
[=] RCM Version: 0x30001

[-] Error 3 receiving response from command

I found several mention of a Linux version of wheelie 0.2 that is supposed to solve this for some, but the androidroot.mobi site is a bit of a mess and all the older links are broken.



OK, got it working again. I left the tablet on the Asus logo screen until the battery died, then plugged it in and charged it for a couple hours.

Attached it to a linux machine and followed this guide: http://rootzwiki.com/topic/35086-guide-nvflash-general-users-guide-unbrickrecoverdowngradeupgrade-tf201/

Just using wheelie and flashing the images wasn't enough - I had to use the "semi-automated recovery" script, which also rebuilds the partitons and sends over additional configuration.

On the linux side, the NVFlash is 32 bit, so I had to install the i686 version of libstdc++, YMMV.

Hi,
I'm having exactly the same problem. Coming from HairyBean tried to install CM11 and the same as above.
Does anyone know how to fix it with a Windows PC. ... By the way I'm not having the Error 3 with my "old" wheelie ... just getting it when installing a newer wheelie. But at the end it doesn't matter the result is the same. Prime freezes at the Logo cannot access recovery or fastboot just wheelie "old" is working installing all the blobs doesn't fix.
Help would be highly appreciated.

Thanks

I get all the way to nvflash --resume --read 14 factory-config.img and then I get an error "file create failed NvError 0x30010".

I've rebooted and still get the same error. If I close out the command prompt and try again it just hangs.

Any help appreciated.

Ok, I figured it out. I had to open my command prompt as administrator.

My devices is unlocked, but i don't activate nvflash so i don't have my proper Blob file.

I Will pay if anyone really help me with success to unbrick my TF201, really !

Thanks a lot,

You are my last hope....

I cannot speak for the others but I personally would not be impressed with this outcome. It is not like other rooting methods and other tweaks, this carries a high brick risk. One-clicks and all those types of installers trivialize the risk that we are trying to make users aware of. Making someone read the instructions gives us the opportunity to really reinforce the risk that you are undertaking.

So great community developers like wugresh, chainfire cfrooter, unified android tool developer etc that creates adb GUI devices to semi automate processors are doing the android Dev community a disservice? These are the best devs in the community and they develop programs and apps to help others for free, and are usually very happy to offer help and clear concise how to's to newer people in this community. Its called progress, that's what developers do, write computer programs to simplify tasks ( jobs) for the wider community, you wouldn't have a PC or even a mobile phone if nobody helped anybody by not developing software tools... I agree the tf 201 is a *****, I had one for years, it unlocked via Asus method, rooted for all intensive purposes, su and busybox ran, all rooted apps ran, but it could not install Roms from twrp or cwm, it would stall halfway through, I had to reboot to recovery then reboot.? This went on for months on end, I'd leave it a box somewhere and pull it out again months later when I was ready for the challenge, or bored!. Untill eventually in frustration I totally bricked it, by that time I already had a nexus 10 & 7 so it was outdated and retired anyway. It was also the ist android I learnt these methods on.
Point is if some good talented Dev who can actually write programs ( as against those knowing how to enter a bit of code in adb, and think they are the ducks nuts because of it and anyone who hasn't grasped it yet are morons ) then maybe I wouldn't have gone through all that frustration and could have had an updated tf201, as Asus only did one update in the three years I had it., it was a great concept android device and I believe the first detachable, great build quality but the 1gb ram basically outdated itself too soon.
Anyway I get sick of reading these replies like just google it,or if you can't use code in adb shell then you shouldn't be custom romming your phone.
Everyone starts somewhere and usually asks for a bit of guidance when they do, even you criticalis I bet, so I would say if you can't add something constructive or positive to the conversation then why bother answering at all? Forums are communities, which mean all members are part of that community, so show some respect and try and help people and if you can't, or just an angry young dude on a negativity troll trip, try and curtail your incessant need to put down others, when your feeling that way just walk away from your computer and go breathe some fresh air, take a walk, have a break, you will feel so much better asfterwards

Hard brick although a working blob.bin file has been created?

First of all, I would like to express my thanks to all developers who made nvflash working on the TF201! Your support is really appreciated and I can confirm that it already saved me from hard bricking my Prime in at least two cases. :fingers-crossed:

However, the best preparation is not always a absolute guaranty to avoid hard bricking as I have faced now: Although, I created a working blob.bin file by flatline recovery, I can't get into apx mode anymore. Maybe, I made some stupid mistakes, I don't exactly know :crying:. I tried to flash multirom on my TF201 device by using an unofficial version for the Asus TF300t tablet. At first it was working, but I noticed that the device recognition got mixed (the TF201 turned into an TF300t) and I experienced some problems during installing some custom roms for the TF201. I tried to undo the changes to get cm11 working again. However, the flashing process was not sucessful. Then I lost control over my tablet. I couldn't enter bootloader anymore including fastboot or recovery mode. However, while trying to press the hardware keys to enter apx mode, I recognized that the display of my TF201 remained black (which is actually a good sign because it should be like that during first stage of this mode).

However, as mentioned above my tablet is not recognized as apx device on my PC anymore after connecting it via USB cable. I was not successful, neither under Linux nor under Windows. Under linux I could not find any entry for the device by checking the lsusb output.

Is there any idea, what I still can do? Any constructive advices are very appreciated!
