anybody giving help here?

I was able to finish all the processes and was able to get the nvflash on my tf700

After all said and done im at the whats next step

i ran the

nvflash --resume --rawdeviceread 0 2944 bricksafe.img

nvflash --resume --read 14 factory-config.img

nvflash --resume --read 7 unlock-token.img

And everything was successful...

Now it said on the guide that i should keep these files save with the blob files i got earlier...

Where do i get the img files from? Its not on the internal memory of my device is there a way where i can get it and save it along with the backup blob files? thanks in advance for the help!

*

Stupid me i was looking at the TF700s directory when it was at the directory where i store my fastboot and adb... it didint specify in the guide only told me to keep it safe...
[Asus Transformer TF700] Buehlar:
Those three files will be found in your C:\android-sdk\platform-tools folder on your computer.

EDIT ok I see you already found them :)
[Asus Transformer TF700] blion:
Just followed the guide successfully but want to confirm that these are the ONLY files i need if backup:

(1) blob.bin

(2) blob.log

(3) bootloader.ebt

(4) bricksafe.img

(5) create.bct

(6) factory-config.img

(7) recovery.bct

(8) unlock-token.img
[Asus Transformer TF700] Buehlar:
Correct.:good:
[Asus Transformer TF700] blion:
Thanks mate! Now gonna try cleanrom!!!!
[Asus Transformer TF700] mark324:
So I got my Asus,I upgraded it to stock Jellybean 4.1.1,does that mean I do not have the right bootloader to get nvflash.Right after updating to stock jellybean I rooted and backed up the rom via twrp,does that mean it will still be bricked if I flashed a custom rom,and will not be able to recover from that backed up stock rom I just made?

I only install Cyanogenmod most of the time,I don't mess with other kernels other than what cm uses,would you say it is safe to take the risk of installing cm without nvflash,if not,will there be any updates soon on getting it to work on newer bootloaders.
[Asus Transformer TF700] _that:
There is currently one well-known bricking situation, and it is easily avoided: Flash a recovery that is too old to work with the JB bootloader, choose "wipe data" in the bootloader menu -> the bootloader always tries to boot the recovery and you can't get into fastboot or Android -> game over. I'd personally stay away from "wipe data" in the bootloader menu altogether.

Safe enough if you always ensure your recovery works before doing anything like "reboot into recovery" or "wipe data". Always start a newly flashed recovery with the power/volume button combination first until you know it boots up fine.

Unlikely.

!!! Help with nvflash !!!

Hello community, so I just received my brand new Asus Infinity Tablet today in mail and am quite excited about it being this is my very first Android tablet. I would absolutely love to perform the NVFLASH method as I have Build Number: 9.4.5.26 with a Firmware upgrade available from Asus (assuming it is the 4.1 JB upgrade). I understand this makes my device absolutely "unbreakable" however I must say that I am quite nervous to perform this procedure myself. I have been searching everywhere for a video tutorial that can guid me along in the process but I cannot seem to find one anywhere. My question is would anyone be able to provide me a video tutorial to show me the step by step procedure in completing NVFLASH successfully or even better would someone be willing to perform this task for me. I was thinking maybe we could do a Team Viewer session on my PC. I would appreciate ANY help or guidance the community can offer me with this request as I am ready to begin flashing ROM's ASAP.
[Asus Transformer TF700] Buehlar:
Do NOT update to JB if you want nvflash access.

Have you unlocked your device and installed sdk tools on your computer?
[Asus Transformer TF700] TYMO68:
No, I haven't done anything yet not even unlocked my device because I want to be sure that I am doing it correctly all the way through without any hiccups. I am familiar with how to unlock and can proceed with installing SDK on my PC but as for the process to continue with NVFLASH, I am hesitant to perform it.

---------- Post added at 07:53 PM ---------- Previous post was at 07:45 PM ----------

Well, I may be in luck if someon can confirm this. I found the following youtube vid on a NVFLASH tutorial:

wwwyoutube.com/watch?v=VMHXeYMgPy4

Can someone confirm with me if I follow this tutorial exactly would it work for the Transformer Pad Infinity version that I have? I noticed that the video is quite "dated" as far back as 2011. Upon completing NVFLASH I am wanting to flash CROM(I) on my tablet as my ROM DD.
[Asus Transformer TF700] Buehlar:
My advice is to read through the entire thread a couple of times as it will help point out where people have made mistakes...found solutions...etc.

Follow the guide here: http://androidroot.mobi/t3_nvflash/

If you hit a snag during the process, post about your issue.

Lots of experts are here to help :)

Will it work if you can downgrade back to ICS .26?
[Asus Transformer TF700] tweeklulz:
you can't downgrade to .26
[Asus Transformer TF700] buhohitr:
Once you upgraded to ICS .30 and above, you can not downgrade back to ICS .26. It's a one way street. Once you're gone you gone....
[Asus Transformer TF700] mark324:
what luck,guess I wont be doing any customroms on this thing...one question,is this nvflash thing exclusive to ASUS ...I rooted my friends Galaxytab 10.1 and installed cm10.1, am wondering now if I should have,if I need this nvflash also for this tablet.and my GS2 for that matter.
[Asus Transformer TF700] Buehlar:
No sir, if you have already upgraded to ICS .30 version or any version of JB then nvflash through ADX mode is not currently possible.
[Asus Transformer TF700] buhohitr:
In my case I'm unlocked and no nvflash, I flash rom/kernel about 3-4 times per week, sometimes 5-6 times per day. I belive most of bricked devices were caused by operator's error, since stock is so bad that I really hated my device until I unlocked and running custom rom/kernel. Anyway it's my case, yours maybe different. To your second question, GS2/Galaxytab 10.1, they do have nvflash, do a search for "nvflash for galaxy s2", you should find info on this.
[Asus Transformer TF700] Buehlar:
Galaxytab 10.1 nvflash info http://xdaforums.com/showthread.php?t=1130574
[Asus Transformer TF700] mark324:
My tab is also unlocked and no nvflash on JB ,so you think I will be safe to install if I am careful,on my gs2 on installing a rom,I would do the norm,wipe data/factory reset,and Dalvik cache wipe on CWM,that is the regular steps to do it right? As long as I do not wipe data from the bootloader.

Also Ive looked up GS2 and Tab 10.1 nvflash,dont seem to be too many about it,I'm not too worried about it now since Ive had so many roms and kernels installed in the past year without any bricking other than bootloops,which were easy to fix by restoring thru CWM..
[Asus Transformer TF700] buhohitr:
Most of issues caused by flashed a wrong version of custom recovery, I think it's pretty safe, just like your phone.
[Asus Transformer TF700] mark324:
ok thanks
[Asus Transformer TF700] Bobg1231:
Just a heads up to anyone wanting to use nvflash. I just received my new tablet and it came pre installed with jelly bean on it. The sticker on the tablet itself now shows "Jelly Bean installed". The serial # starts off with CCOKA so I'm assuming it was manufactured in December (referring to the second C). :(
[Asus Transformer TF700] Buehlar:
Its a shame that the new firmware has locked new users out:crying: Where did you order from? Maybe return it and order from elsewhere you might luck up and get one with a pre .30 bootloader :confused:
[Asus Transformer TF700] Bobg1231:
I got it from Adorama. Got a heck of a deal for the tab and keyboard for $499 plus a $25 gift card. Received them back in December but when I checked the bootloader it was already on .30. It had some light bleed issues so I sent it back hoping for .26 and ended up with Jelly Bean. I will have to say even stock JB is won hell of an improvement over ICS on .30. And for some reason this one actually feels tighter. No light bleed at all, and power and volume buttons seem to be more responsive and might even stick out a little more.
[Asus Transformer TF700] Buehlar:
Ordered mine the 1st week of November, it also came from Adorama but was loaded with ICS .22

Thanks for the info, I have a friend interested in ordering one so its always good to know what maybe to expect when ordering.
[Asus Transformer TF700] deepsix_69:
I got one from Amazon today and it is preloaded with jb as well.
[Asus Transformer TF700] kukailimoku:
Final Checklist Before Updating to Jelly Bean

I would like to be absolutely certain that I've done everything possible to make my TF700T 'brickproof' before I update to the latest ASUS firmware.

Using the AndroidRoot.mobi guide I was able to create the following 8 files:

blob.bin

blob.log

bootloader.ebt

create.bct

recovery.bct

bricksafe.img

factory-config.img

unlock-token.img​

Should I create/backup any additional files or are these sufficient? It appears that additional resources are required in order to recover from a bricked device (i.e. BlobTools, openrecovery-twrp-2.3.0.0-tf700t.blob). Am I correct to assume that these additional requirements can be found elsewhere and are not part of the backup process presented by AndroidRoot.mobi?

Furthermore, It is my understanding that the AndroidRoot bootloader (9.4.5.30r01) allows me to create nvflash blobs. In return, these blob files allow me to retain access to nvflash regardless of any future bootloader's attempt to block it. Considering how important these blob files are, is it possible to step through the guide a second time in order to generate additional copies or will this simply cause problems?

Finally, since I can never get back to ICS .26, are TWRP backups created on this version essentially worthless? I ask because I recently rooted my Samsung S3 and have been able to flip between Samsung's stock ICS ROM and various custom JB roms (i.e CyanogenMod 10) seemingly without issue.

Sincerely,

A Very Appreciative Noob

P.S. I attempted to include links to the guide and files I referenced but as this is my first post the site will not allow it.
[Asus Transformer TF700] _that:
Good. You have all required files. Store them safely and distribute a couple of backups on different media, just in case. I personally stored them in a directory named TF700_C7OKAS... (my serial number), just in case I forget what they are for. :) I also stored the programs used to create and use them together with the files (wheelie and nvflash).

It's very unlikely that you'll ever need to recover using nvflash - but the files you created will always allow you to restore your bootloader, and from there you can use fastboot to install a recovery, then use the recovery to install an Android kernel and system ROM.

Correct - these "additional requirements" are just the normal tools for flashing custom ROMs.

Correct. According to the wheelie devs, APX mode is a hardware feature of the Tegra SOC.

It's possible. The files that come out should be identical though. I think it is enough that you make backups of the files you already have.

If you restore such a backup to a later version of Android, it will think you just upgraded your ROM and will upgrade the data. But theoretically, with nvflash, you *can* go back to 9.4.5.26 from any later version, I just don't think it's worth the effort.

I bricked my device, i attempted to flash it with new firmware so long ago now i cant even remember the version i was attempting to put on it! anyway flash sequence went wrong and now all i have is a tab that when you switch it on .....it displays the asus logo and thats it until the battery runs flat. sent it to asus as an unlocked device. They said they will charge......wait for it 320 euros to fix as it will need a new motherboard.

Im desparately trying to unbrick this tablet, only trouble is don't have NVflash backup of blobs, don't know what versionof the bootloader is on it but APX mode seems to work.
[Asus Transformer TF700] buhohitr:
If you don't have Nvflash and only APX mode is working then you're DONE. You need to send back to Asus.
[Asus Transformer TF700] cpascal:
Well in that case, it looks like I have a new shiny doorstop.

I've sent it to Asus already, refuse to pay 320euros, complete rip off!

I'm sure they'll have some fancy flashing machine there that could probably re-flash the eprom in minutes!
[Asus Transformer TF700] mrjayviper:
but you unlocked it knowing the consequences... :eek:
[Asus Transformer TF700] viewer2008:
Here's an idea

you can sell it for parts if you want on eBay and it will get you some cash rather than using it for doorstop. :laugh:
[Asus Transformer TF700] xorob0:
If you bought it in Europe (I see you're talking in euro) they must repaire it for free as you have a 2 years guarantee and don't let they say they cannot repaire because you unlocked your bootloader, they must repaire it unless they prove you modified something hardware.

You're not at the right directory where fastboot.exe is located. Make sure you locate the directory where fastboot.exe is in, the execute from there.

I just received my TF700t back from RMA. I asked them to put 10.4.4.25 on it.

I haven't done anything to the tablet yet. If I unlock now, will I be able to use NVFlash now? :confused:
[Asus Transformer TF700] 7786:
Nope, you will not be able to use NVFlash.

Just got a spanking new TF700 from Best Buy as a warranty exchange for my (unlocked!) 8 month old Tab with a dead screen! Came with the 9.4.5.26 firmware(!), so I was able to get NVFlash access and I have generated my blob and img files. I was able to follow the guide to do this, but I am new to NVFlash - is there a link for the instructions to restore my Tab, if necessary? I have searched, but not found.

Thank you all for your great work!

[Asus Transformer TF700] smalis:
Thanks, that works. TF201 instructions, but they can be applied to TF700.
[Asus Transformer TF700] TitanUranus:
Help please.

After a bad flash my TF700 kept telling me it couldn't do anything and gave me a menacing "'Unrecoverable bootloader error" in evil looking red letters. Having played around and getting nowhere, I got out the NVFlash backups I did back in November when I got the tablet. I followed the instructions, and it was a very nervous 5 minutes of flashing using APX, especially when after my first attempt it wouldn't even give me the asus logo! I did the whole thing again, and the sheer relief of seeing that Asus logo again was a sweet moment. Now I can get into a recovery mode. I'm stuck now though. If I reboot into recovery menu I get a choice of "wipe data" or that USB symbol - no "RCK" or anything. However, by selecting "wipe Data" I can get clockwork mod to load up (unfortunately TWRP just reboots its self after formatting the partition). So I downloaded and tried flashing the Asus firmwares (yep, all the ones I could get hold of) but none of them worked. I did of course extract them from their double zipped format to the single zip format.

So I'm stuck - what can I do? Where can I find a bootloader I can zip or write using fastboot (or APX for that matter), so I can install a nice ROM and get back to normality? Please help, I'm getting a bit miffed with this damn tablet (which I cant even power off for a while so I can sleep in peace).
[Asus Transformer TF700] buhohitr:
So can you get into cwm recovery? what version of cwm do you have?
[Asus Transformer TF700] TitanUranus:
I have the latest version of CWM (with touch). I think the partition table may be borked or something, 'cause nothing I try to install gets past the Asus logo (with the "AndroidRoot 9.4.5.30rc1" displayed in the top left corner - if I got that number wrong sorry, I put the tablet away as I need a break from it for a few hours).

If I could get an ancient Asus firmware maybe that would rebuild the system so I could get it running well enough to boot. I think there's nothing that will even boot using the bootloader that's in there. All my backups are TWRP, and it just reboots it's self after wiping partitions - there's no "RCK" option available. I suspect if I could get the original Asus recovery.blob it might automatically pick up the firmware update zip on the microSD and rebuild the whole system from scratch (I did this once before, but not from this bad a problem). I'm afraid I'm not entirely knowlegeable in these things, though I'm not exactly a noob (I'd class myself as partially competent - haha).

Thanks for the prompt reply I have to say the reason this hasn't stressed me beyond breaking point is that I know there's help out there and I'm sure it can be worked out eventually. I think when I get it completely fixed I'll do a guide for people who, like myself can read and learn but find the information fragmented in countless threads and posts which seem to go in circles. Like I say, I really appreciate the help.

I'll come back after some sleep, I've been messing about all night.
[Asus Transformer TF700] smalis:
I think you need to flash a recovery image/blob after flashing the bootloader. This thread explains the procedure for the TF201 - the procedure is the same for the TF700, except you need to de-blob a TF700 ROM using blob tools. Blob tools are in this thread.

I am by no means an nvflash expert, but that procedure did work for me. I suggest you follow the entire procedure in the TF201 thread (using a TF700 de-blobbed ROM), and you should have a working tablet. Then, you can wipe and flash a different ROM, flash TWRP, and/or restore a backup.
[Asus Transformer TF700] TitanUranus:
Thanks, I'll check this out later. I'll let you know how I get on.
[Asus Transformer TF700] Hundsbuah:
i thought he did it allready and it doesnt help?
[Asus Transformer TF700] TitanUranus:
I think I did. I followed the instructions in the post in this thread (which I have read all 30 pages of!). I will read through the TF200 guide later to see if there's anything I missed, I cant right now. Do you have any suggestions Hundsbuah?
[Asus Transformer TF700] _that:
What's the current status of your tablet? AndroidRoot hacked 9.4.5.30 bootloader works, but nothing else? Then you need to use fastboot to flash (blobs of) the current bootloader and the current TWRP, then use TWRP to install a ROM.
[Asus Transformer TF700] smalis:
It was not clear to me exactly what he flashed - it sounded like he only flashed a bootloader.
[Asus Transformer TF700] Hundsbuah:
no it sounds he flashed the recovery kernel. but according the red text it seems the bootloader is wracked and he needs to flash the bootloader (i think .ebt? after blobunpack)
[Asus Transformer TF700] smalis:
Yes, .ebt is bootloader
[Asus Transformer TF700] TitanUranus:
I think this sounds correct. I no longer get the red "unrecoverable bootloader error" since I reinstalled my NVFlash recovery files. The problem I have now is that although I can get into CWM, nothing I flash makes any difference. I'm stuck on the old 9.4.5.30 bootloader, and everything I tried so far hasn't been able to update it. Since none of the current ROMS run on the old bootloader, I cant even get past the ASUS logo, unless I hold the volume button down and go to recovery (which has only 2 options, "wipe data" and "USB", if I select "Wipe Data" I can get into CWM I tried flashing TWRP and ising "Wipe Data" it loads, formats data then reboots without letting me touch anything anything.

Can you please tell me where I can get the latest bootloader, and how I flash it with fastboot? I already tried downloading and flashing "10.6.1.14.4 US Bootloader and TWRP 2.5 DOWNLOAD " from sdbags CROMIX page using CWM, but I'm not certain how I can do that using flashboot. Do I just extract the blob? What command should I use in fastboot to write it (so it overwrites the 9.4.5.30 bootloader)?

I was going to try writing the blob using fastboot myself, but my tablet won't start right now as it rand out of battery power. When I plugged it in to charge, a battery symbol appeared onscreen, so at least I know it isn't dead!

Thank you all for being so helpful, it's very encouraging to be able to ask questions about something like this without being called an idiot! I've had a lot of fun trying and testing all your ROMS and I'ts really amazing to see how much you all care about helping someone like myself recover from a porblem. I wish there was some way I could pay you all back. Perhaps I can a little, by helping someone else who get's into trouble in the future.

EDIT: I just got it working. I used the "10.6.1.14.4 US Bootloader and TWRP 2.5 DOWNLOAD " from sbdags, extracted the blob then used the following command in fastboot:

fastboot flash bootloader blob

fastboot reboot

It's really easy when you know how, but I think my brain was a bit fried after messing about with it for so long last night! Thanks for all your help and support.

------------------------------------------

Now I have a new problem, I cant flash anything. Top corner says

"Key driver not found.. Booting OS

Android cardhw-user bootloader (1.00 e) released by "US_epad-10.6.1.14.4-20130329" A03"

If I boot into TWRP is asks me for a decrypt key, and doesn't let me do anything.
[Asus Transformer TF700] _that:
OK, that's the latest bootloader. What do you mean with "TWRP doesn't let me do anything"?

I've never done it, but you could try "fastboot format userdata" (which should format /data) - if that doesn't work "fastboot erase userdata", and then start TWRP again, maybe that helps.
[Asus Transformer TF700] smalis:
Download the JB stock rom from ASUS website - I think it is V10.4.4.25. Then unzip that file - mine unzipped to US_epad-user-10.6.1.14.4.zip. Use the blob tools in my earier post to unpack the blobs from that zip file. Then, follow the NVFlash sequence in the TF201 guide thread from my earlier post and flash all those blobs in the correct order. You should then be on working stock with the latest bootloader, and you can fastboot TWRP and go from there.
