I have a TF300 with cm10 since two weeks.
I have install Rom manager to. He ask me to upgrade cwm. I do that but I don't reboot.
The sunday after, I have install last CM10. After download, the tablet reboot. Now I have only the logo asus and the string "The Device is Unlocked". Nothing else. I try fastboot mode but nothing else. I try apx mode. It work, the device appears in windows device manager.
My question is, can I put CWM on the tablet in apx mode ?
None of the answer in different forums works.
I need help.

This is the wrong cwm for your unit; it is for TF201.
This link provides help for your problem. http://forum.xda-developers.com/showthread.php?t=1680570
Look for this heading in the link posted above. - Flashed TF201 Recovery in ROM Manager?
In answer to your question, no.
Good Luck!
The problem is that I can't use fastboot. I only have apx mode than adb command doesn't work.

Without nvflash previously installed I have not heard of anyone getting any use of apx.
My understanding you have three choices to recover your unit.
ADB, Fastboot, and recovery. In your case current recovery is out since we know it is the wrong one, that is unless you can flash the correct one.
I have read of people flashing with adb and fastboot even when the unit appeared not to respond and getting their unit restored.
So give the commands even without a response.
On most units when in cwm recovery adb works.
Also with fastboot commands try ( this example would be to flash twrp recovery )
fastboot -i 0x0B05 flash recovery twrp.blob
fastboot -i 0x0B05 reboot
then try
fastboot flash recovery twrp.blob
fastboot reboot
I know the -i 0x0B05 designates our Asus but at this stage your unit does know what it is and may be refusing based on being called Asus, so give the generic command if the normal ones don't work.
I have also read where you use the drivers from tf201 for adb and fastboot and getting their unit to respond. http://downloadandroidrom.com/file/TransformerPrime/drivers
I believe other drivers tried after tf201 were universal naked drivers.http://forum.xda-developers.com/showthread.php?t=1766220

With universal driver, my pad is now reconize under windows. I can push recovery.img with nvflash but I doesn't work. Still block on ASUS screen and I can't access to the recovery.
I think the problem stay on another partition. Can someone do a backup of a TF300 and share this backup ?

Sorry, time to collect some info.
1. Before all of this began were you on ICS or JB?
2. The exact command you used to flash recovery.img with nvflash?
3. Exact wording for Asus block?
4. The backup you want? Stock recovery, cwm recovery, twrp recovery, boot, system, etc?
5. What kind of backup, img, blob, etc?
I know this is a lot but necessary so you are working with what you want and not what I think you want.

This is what I believe them to be and matches your nvflash.cfg file ( or whatever the nvflash cfg file is named).

I use nvflash from a package named "tf300_nvflashpack".
There is a command named wheelie who need a file blob.bin

Here is the info from the nvflash guide page.
To “bootstrap” into nvflash using wheelie simply run the following command:-
$ wheelie --blob blob.bin If successful your device will boot into nvflash mode and the bootloader screen will appear on the device.
To me this appears as you rename bootloader.bin to blob.bin which I could have done when I created it. I guess I didn't look far enough ahead.
I am going to provide a link to some random info about the restoral side of nvflash.
http://forum.xda-developers.com/showthread.php?t=1962350
You may find it of use, or not.
I don't think you can backup. The file you need to flash to begin backup is flashed with fastboot and is created for the ICS bootloader. I think that would mean absolute brick if you flashed it.

I believe $ wheelie --blob blob.bin is trying to access ebtblob.bin the first thing flashed when setting up nvflash which is the AndroidRoot bootloader. I have an etb blob from the origional blob file ( blob-10-4-2-17.EBT ).I think the one in nvflash folder would brick your unit completely. I can set this file up for you to download if you wish. I'll just put it up and you can decide. http://www.mediafire.com/?c9ybblcq49n61xr
I was just reviewing a thread I helped with previously. It brought something to mind I don't believe you have tried.
An attempt to get into fastboot. Power device on, press and hold volume down and use paperclip to press reset. Several times this has worked to get into recovery or fastboot when nothing else helped.
Reset is located approx one inch or 25.4 mm below the sdcard.

I had forgotten to mention something important.
As you go through trying to sort this problem don't forget to recheck adb and fastboot access. I know it sounds silly but sometimes the most minor change or another reboot will give you access that was earlier missing.
I always block on the asus logo. I can't make apx works. I try upgrade on sd card but it does not work to.
Someone does have an idea ?

You flashed a PRIME rom to your tf300?
First of all, we should know which firmware do you have before your tablet doesn't boot (Stock ICS, JB, Custom Rom).
Then, you can use fastboot to recover your tablet (i did it a lot of times). Try steps below:
1. Download latest oficial Asus firmware (V10.4.2.13). BE SURE to download your region (WW, US, etc...)
2. Extract downloaded zip and take blob file.
3. Download Android SDK and install them on C:\ (http://developer.android.com/sdk/index.html)
4. Execute SDK downloader and mark tools and platform-tool options for download.
5. OPTIONAL add tools and platform-tool folder to PATH, after that test if fastboot command runs on CMD.
6 Copy blob file on same SDK folder.
7. Connect TF300T with usb cable and put it in Download Mode (USB icon on recovery menu)
8. Wait until drivers are installed.
7. Open CMD, go to Android SDK folder and then type command below:
fastboot -i 0x0B05 flash system blob
wait 2 or 3 minutes and then you'll see a message that send and write was OK. Now type this command:
fastboot -i 0x0B05 reboot
And It should boot again.

Yes, that's right, but I suppost if he tries to flash a custom rom he has already unlocked his device. You can't flash any rom without unlock bootloader.
I cant do anything apart from get on to apx mode, from apx mode how do I use command to flash back.
My tf300 is ics, unlock.
when i connect usb to pc. i press power and volume up. thats only things i can do.
so what do i do next?
thanks.
The same problem.
I only see: "device is unlocked" or something like that. And nothing go on.
Is it totaly bicked or is there any chance to restore it?
Please advice.
Did anybody ever figure this out. I'm in the same boat. Can't do vol down+power to get to recovery. But if i do volume up+power it shows in device manager as transformer prime apx interface (even though it's just a tf300)

no way to unbrick tf300t
Funny, I bricked my tf300t without doing anything. One day it just got stuck in asus screen.
tried to recover, nothing happended.
tried hard reset. Nothing.
Wipe data: result: bricked tablet.
I'm looking for information it is defintely impossible to unbrick it.
Anybody else with the same situation can tell you that.
Nobody has even been able to do it.
If you send it to Asus they provide a new tablet.
Conclusion:
TF300T is a terrible product, as any other asus product i assume. Amazing that you can brick a tablet without even trying to flash it or without even being connected to a computer.
It bricks by itself. Hundreds of other users can confirm it.
My advice: dont by asus products
If you already have one, dont use wipe data as anybody who has done it has ended up with an expensive useless brick.
Odp: [Q] How to unbrick my tf300
I don't agree witch this, only think what you not should use is t the wipe data from bootloader menu - I already flashed many times not working kernel, get really often bootloop - the problem is - much users going to made stupid things when the get a soft bootloop - If you get this first try wipe data from recovery, if this won't help, try to format data from recovery - often happends that the ext4 filessystem get broken. Recovery should allowa us to run fsck on data - I fixed my bootloops many times with it without loosing my data.

OP,
I think your anger is misdirected. The device, as it comes out of the box, works 100% without issues. YOU as a user decided to make changes that could potentially brick it. YOU chose to follow the steps with the full disclaimer that it can/may brick your device. So at the end of the day, its' not the fault of ASUS or the device for "bricking itself"; the responsibility of your actions lies on your own shoulders.
That being said, Asus will not provide warranty support for a tablet that has been unlocked. This is clearly stated in their unlocker app. So no, they won't "send you a new tablet" if you send it to them (unless you pay out of pocket for the repairs).
I've done just about as bad of a brick as I possibly can on my tablet and recovered just fine. It was just a matter of being CAREFUL, reading instructions three times before l followed them, and asking lots of questions. But what ultimately saved me was the NVFlash tool, and for that I am eternally grateful.
Just my two cents.

I have problem that my partitions won't mount at all. I have access to fastboot, CWM, and adb but no matter what i cannot access my partitions and so i cannot install zip from CWM. When i try blob within fastboot my tablet just freezes.....
Hi, what happens if I have no access to fastboot? It loops in the ASUS logo and what ever I do, can't gain access to recovery because it doesn't get into fastboot. So how to solve it via APX? Thank you.
You wont solve the problem unless youve done a nvflash backup. If you tablet is recognised as APX while plugged in PC, then you have an unrecoverable brick. If nothing appears when you plug it, then try on another PC.

Hi,
I am having a similar problem to the one described. I have unvblocked my TF300T and installed CWM recovery (v. 6.0.2.3), but it can't mount any filesystem, so I can not flash anything. The boot menu is gone (RCK, wipe tablet, android) and when I switch the tablet on It just goes to CWM. If I connect the tablet to a PC, I can send commands with adb from my win 7 PC (for instance "adb reboot" will reboot the tablet), but fastboot doesn't work (it keeps "waiting for device"). Prior to this my android version was JB 4.2. I didn't make any backup, so I am fearing the worst outcome. Did I brick my tablet for good?
Thanks a lot for any reply.

i want to resolve this problem with you to install the best rom for this model.
Thank you very much and sorry for my english, i am french but i understand your paragraph.

If you have mounting / PIT errors you could try my solution as described here:
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
no guarantee though but it basically wipes your device so that you should be able to flash the blob file back.
also if your tab still is ICS- check if you are using the correct recovery - also bear in mind that cm10.1 afaik uses the new 4.2 bootloader and probably wont work with ics based PIT devices.

fastboot erase userdata OK
fastboot erase boot OK
fastboot erase misc OK
fastboot erase cache OK

The message is the same like previously, always the problem of space.
I tries the method by copy the blob file on different directory on my computer and on a usb key too.
Always the same problem of space
I think the problem is the space on the tablet but i dont' understand. I erase system, recovery, userdata, boot, misc, cache, i think the tablet is empty.
Can you help me please ?

I already tried the first method some times:
using blob from official ICS from Asus (versions 9.4.3.30 and 9.4.3.29)
about the recovery I tried ICS CWM recovery, 2.6 ICS TWRP recovery and 2.4 ICS TWRP recovery
without success accessing that menu where I can select recovery, fastboot, android or wipe.
when I try turning the tablet on holding Vol. Down I get that message on my first post.
Then I tried once the second method (the one using bricksafe.img). Still the same.

Should I post about this on your thread about the nvflash?

I don't think it will make a difference.
I have not forgotten you. I glanced through the nvflash thread and found little attempt to help in most cases. I have been through the 100 and the 201 threads and have started through the 700.
I have started reading through the complete 300 thread and taking notes. I did make one addition to my first method of recovery. You might want to try it again.
I have spent several hours and feel I am near completion. I have a new method on paper but I still need to test on my tablet and refine it before suggesting for anyone else to use.
Could you tell me how you came to this point with your tablet? It might give me some insight into what needs to be done.

Thank you very much.
Well, I was on some CM10.1 nightly with TWRP, I was going to update to the latest nightly and wipe. I misclicked and wiped the /system.
I installed the CM10.1 and gapps ok. But it wasn't working, the boot was looping.
Then the recovery wasn't working either and there was no option to fastboot.
The first time I tried restoring the nvflash it worked all ok. Then I updated to JB and the recovery was broken again, so I tried the nvflash restore again and that's where everything started.
I tried that new method, only difference the wheelie didn't allow me to use --resume so I used the -r.
But the problem still the same
Maybe that menu where I select recovery, fastboot, wipe, android is broken? because that message shows only when I try to boot holding vol. down.
I already flashed lots of gadgets and never had this kind of problem, I think I wasn't paying much attention when I wiped the /system hahah

Your bootloader (ebt) the menu you mention with fastboot etc. was replaced in the first method.
Your files from blobunpack are from ICS 9.4.3.30?
The asus tablets are an odd breed. Asus created a mess with the bootloader and have continued to make it worse and worse.
Here is some info you may find useful that I posted in another thread.
Bootloaders have been an issue on this tablet since 4.1 (JB) arrived.
I swap at will between the JB bootloaders using stock recovery - next bootloader up or down.
Yes, be careful! Match bootloader, rom and twrp.
Here are the bootloaders, stock roms, and twrp- now you have to match your custom rom.
4.0 bootloader - 9.4.3.17, 9.4.3.29, 9.4.3.30 - twrp openrecovery-twrp-2.5.0.0-tf300t-ICS.blob
4.1 bootloader - 10.4.2.9, 10.4.2.13, 10.4.2.17, 10.4.2.18, 10.4.2.20 - twrp openrecovery-twrp-2.5.0.0-tf300t-JB.blob
4.2 bootloader - 10.6.1.8 - twrp openrecovery-twrp-2.4.4.0-tf300t-4.2.blob
4.2.1 bootloader - 10.6.1.15.3, 10.6.1.27.1 - twrp openrecovery-twrp-2.5.0.0-tf300t-4.2.blob

I unpacked the 9.4.3.30 again
Downloaded the TWRP 2.5 ICS blob file
and tried the nvflash again with those files, the problem still the same.
It's weird, because the first time it worked perfectly. with the same files.
I'll try using the 10.6.1.27.1 and TWRP 2.5 JB

I'm still refining my next offer. I'll give you a shout when I'm finished - testing is in progress but slow.
The only way I found to emulate your tablet was to flash cm 10.1 while running stock ICS 9.4.3.30. The next hour was spent just getting the computer and tablet to communicate. I had to boot linux and use it to gain access. Once I used linux to nvflash 9.4.3.30 bootloader, boot, system, and twrp recovery windows recognized the tablet again but I still had no bootloader menu or useable tablet.
About an hour and a half later I had a fully functional tablet. I can't post or suggest the method I used used to recover as it borders on insanity.
Later tonight I'll try for a much safer and simpler method.
Thanks
I tried with the JB files. But no success
I will wait for your new method

You're going to need some other help. I have not been able to find anything that is repeatable even with the same brick each time.
Go ahead and post in my nvflash thread and I'll let your post pass. Maybe someone else will respond (it is not a popular thread to post, although many have used the info).
How many posts do you need to be able to post in the developers section?

Ok, thanks for all the helping.
I think at least 10 posts.
Is there any way to erase everything before flashing the files? I don't know, maybe there are some data getting in the way.

Erasing can be done with fastboot.
Here are the ones I know.
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 reboot
I just finished reading the tf700 nvflash thread. They are using the following commands as a standard and I have seen these used on our tablet. I can't prove this at the moment as I have a screen issue.
wheelie --blob blob.bin
nvflash --resume --rawdevicewrite 0 2944 bricksafe.img
nvflash --resume --download 14 factory-config.img
nvflash --resume --download 7 unlock-token.img
nvflash --resume –go
I'll look through my notes and give you the info I have for the Nvflash IRC.

Hi,
But I can't access fastboot mode
I tried those commands alone and tried combining with the ones on your guide but no success.
I guess I'm out of luck.
When you restore your blob files, does your tablet boot ok? Because mine keep on that ASUS logo with that rotating loading image.

Sometimes I have the booting problem you describe as well as boot looping. I can usually get a normal boot by pressing volume down and pressing the reset. Then let the tablet cold boot. If that fails I'll use wheelie and then nvflash to reboot.
wheelie -r --blob blob.bin
nvflash --resume --go

I tried several times but nothing different happened, I don't know what's happening that my bootloader menu doesn't show up.
What could interfere with this? Besides the blob.ebt file.
When you restore your device what rom and recovery you use?
Thanks.
So two days ago my tablet came back from the service center they repaired my faulty touchscreen yesterday i installed a rom and then did nvflash today i decided to upgrade to the latest bootloader 10.6.1.27.5 and everything went fine after the update I rebooted my tablet and whenever it reaches a state at the spinning asus logo it just freezes for 10 seconds and then reboots?? it happens to every rom i install?
any help?
thanks,
noahvt
Which way did You upgrade? Did tablet boot in android at first time or You reboot it from other mode?

I flashed the rom via fastboot flash ... then i flashed twrp i wiped everything and then i installed the zip file from twrp and then it installed it it rebooted and then the problem started!
What zip it was? Looks like reflash rom through twrp or fastboot should solve problem.

And now the screen is completly black i can't turn it on or get into apx or bootloader any tips?
Apx - hold volume up and power. Bootloader menu - volume down and power.
unfortunately both do nothing
EDIT: i had to make use of the reset hole to get into apx mode: so now i am in nvflash what do i do now to restore my device i've made a backup of every partition!
Try method 7 to enter APX or bootloader described here.

I don't have a backup of blob.app i only have the file"09_APP_raw.img" can i do something with that?
(and I also have: bootloader.ebt, bricksafe.img, factory-config.img, partitiontable.txt, recovery.bct)
It goes from unpacked stock rom.
how do i use it then because i used it to flash to the "10" partition and now i get unable to mount /system in twrp
okay i flashed the blob using fastboot and then flashed twrp: the error is gone now
To recover You need blob.bin and recovery.img from nvflash backup. blob.EBT, blob.APP, blob.LNX should be unpacked from ROM same android version as You'r nvflash backup. Nvflash recover manual have link's to blobtools which may unpack stock ROM blob and blobtools manual. So read all that things wisely and redo it right way. And after process of nvflash recover You may need to flash ROM through custom recovery to make it work.

all of that didn't work still bootloops (btw when i flash a rom through recovery it takes 5 seconds!! and through fastboot writing the system only takes 124 seconds)
EDIT: also my tablet reboots after each nvflash -r --download is that normal?
What android version did You use when nvflash backup was done? What android rom did You use to grab blob.EBT, blob.APP, blob.LNX? What recovery version did You flash after restore? You can also try wipe all partitions and reflash rom.

Yes, just reenter to APX and redo "wheelie -r --blob blob.bin".

i was on android 4.2.1 when i took the backup (10.6.1.15.3) I also used the 10.6.1.15.3 files and I flashed twrp after the restore!
Try do not flash twrp and wait about 10-20 min after last nvflash command (nvflash --resume --rawdevicewrite 0 2944 bricksafe.img). Also try flash blob.SOS from ROM instead recovery.img from backup.
Sorry, I'd thought I'd posted under Q&A/Help. Not sure if a moderator can move it where it belongs?
My tf300t (ICS v9.3.4.17) is unlocked, rooted, and has TWRP 2.6.3.0 installed. I also have created the nvflash backups so it's currently running on the AndroidRoot v9.4.3.30r01 bootloader. I've stayed with
ICS and not updated anything except TWRP, but was just about to update to either ICS v9.4.3.30 or jump and install the latest JB.
Earlier today I went into Terminal Emulator, typed su and reboot as I've always done. I thought my tablet had shutdown because the screen stayed blank. I tried the power button and nothing so thought
maybe my power button had given out. I then tried plugging in the charging/usb cable which normally would get it to boot and again blank screen. Last I tried connecting to my pc and found it was in
APX mode. I'm able to boot up from nvflash and function normally but I'm stuck once I shut off the tablet from ICS (have to rerun nvflash to boot up again).
When I power off from APX mode, it automatically restarts back into APX mode. I was able to get into TWRP and tried restoring my latest nandroid (System, Data, Recovery, & Boot partitions) but no
change. Also tried a factory reset but same results - booting into APX yet again...
Ack, at this point I'm about ready to punt. I have my backups (TB & Helium) and am thinking of trying to update to v9.4.3.30 to see if this clears up booting into APX mode. To do this, can I just install the single
zip using TWRP & then re-flash TWRP using adb (or fastboot assuming I get it back)? Or do it via nvflash? If by nvflash, are these the correct commands after unpacking the v9.4.3.30 blob:
nvflash -r --download 4 blob.EBT
nvflash -r --download 10 blob.APP
nvflash -r --download 6 blob.LNX
Thoughts or ideas are really appreciated!

WoW that is an old bootloder..... v9.3.4.17 What is the SKU of that bootloader??
Enter APX mode and bootstrap in, If thats the ways its done.. I don't know because, I did my nvflash after jb came out...Run this command
Code:
nvflash -r --go
It will not reboot your tablet but it is supposed to let the bootloader resume on go which should be the next boot....
Just long hold your power button and let your tablet boot normally... Let me know if this helps at all... Thx lj
O yeah just be aware that the newest version of TWRP is having some issues... Just a FYI

Thanks for the reply. The bootloader is the original one loaded when I created the nvflash backups. When rebooting from nvflash and holding the vol down button, I see:
Android cardhu-user bootloader <2.10 e> released by "WW_epad-9.4.3.30-20120206"
This had to have been universal for all that ran it way back when, though the SKU on my tablet is US (US_epad-9.4.3.2012...) and no real issues in over the year I've had it.
The nvflash -r --go command is the same as nvflash --resume --go...both reboot the device (nvflash help verifies they're the same).
------> Back to the issue at hand *sigh* <-----
So... I'm still having to reboot from APX mode using nvflash and hold the volume down button. At that point I can either enter TWRP or leave it go and it'll cold boot - no icons
display for fastboot, etc. It just shows:
Platform Pre OS boot configuration...
Cold-booting Linux
And then it will boot into ICS, though found it may just go back into APX mode again. It can take several tries, but it'll finally boot properly.
Sooo...what's my next step? Have noticed TWRP 2.6.3.0 seems to be a bit flaky in the past. Should I try installing US_epad-user-9.4.3.30.zip using TWRP? I have
OTA Rootkeeper installed with SuperSU so root should either remain or be restorable (fingers crossed). Or do I need to use nvflash to flash each partition? Or finally go
back to my original nvflash blobs? I really don't want to move forward and screw up something worse than it is!
Side note: I've tried to install tried & true TWRP v2.3.1.0. Using adb, it appears to flash successfully, I reboot into ICS, and then nvflash boot into TWRP - but I'm still
on v2.6.3.0. Possibly not rebooting smoothly into ICS isn't allowing the img file to take? For now will deal continue using my installed version v2.6.3.0 I guess...
Thanks for direction on where to go next! And if can, spell out my steps to take in detail (sometimes I may be a tad dense and don't mind any eyestrain, lol).

Ok so you are 100% sure that you have had a US SKU version bootloader from when you got it new????
Where are you getting the firmware zip file from??
And you think this all started because of a wrong recovery flash???

Thanks for the quick reply... I'm positive on the US SKU - I have a screenshot I took of the SW info when it was brand new - here it is:
http://i1331.photobucket.com/albums...delampSWinfo-2012-11-25-07-29_zps27ba6fc6.jpg
As for the earlier firmware zips I've got, they were provided in one of the XDA posts - possibly this one: http://forum.xda-developers.com/showpost.php?p=33883254&postcount=3
Nope, it just suddenly started while using the tablet normally. No flashing, restoring nandroids, etc in at least a week or two. I was playing one of my games on the tablet and sometimes the graphics will act
funny or it'll fc on me. So I either do a cold restart or reboot using Terminal Emulator to get the behaving normally again. In this case I rebooted using Android Terminal and suddenly only had a black
screen. Finally realized it wasn't powered down but was going into APX mode... Sorry, just tried flashing the older version of TWRP I'd always used since v2.6.3.0 has been flaky off and on. V2.6.3.0 was
originally flashed about 2-3 weeks ago and I'll just stick with it while working on fixing this!
The only thing I can think which may be unrelated. My daughter loaded a non-market game that was tagged as having Android:Fujacks by Avast! Being non-market, maybe foolishly? I let Avast
uninstall it. But I'm almost positive I rebooted a few times after without any issues. Also restoring an earlier nandroid didn't help, so don't think it's the system or data partitions messed up. Could it
be the boot partition that's gone funky?
That's why I'm wondering if an "upgrade" to v9.4.3.30 would clear this up - and if so, best/safest way to do it? Hope that helps fill in a little more!

a black screen. Finally realized it wasn't powered down but was going into APX mode.
The only thing I can think which may be unrelated. My daughter loaded a non-market game that was tagged as having Android:Fujacks by Avast! Being non-market, maybe
foolishly? I let Avast uninstall it. But I'm almost positive I rebooted a few times after without any issues. Also restoring an earlier nandroid didn't help, so don't think it's the system
or data partitions messed up. Could it be the boot partition that's gone funky?
That's why I'm wondering if an "upgrade" to v9.4.3.30 would clear this up - and if so, best/safest way to do it? Hope that helps fill in a little more!

It's the normal Stock v9.4.3.30 update from ASUS. It's the "US_epad-user-9.4.3.30.zip" which in turn contains the META-INF folder and the blob file. The blob file contains:
blob.APP ; system img
blob.EBT ; bootloader.bin
blob.LNX ; boot img
blob.PT ; partition table I presume
blob.SOS ; stock recovery img
The blob names are exact and I think I have each identified as to their purpose going from old notes. EBT, APP, and LNX are the three that I believe could/would be flashed using nvflash
if necessary (if can't just install the full update zip & reinstall TWRP over the stock recovery)...
Is that what you're looking for?

We need to get to fastboot and verify that we can see your devices boot into the bootloader screen.. As I recall you should have a
usb icon you must select to enable fastboot... Can you get to this point??

No, the icons one normally sees are missing/not available to be selected. When I reboot from nvflash & hold the vol down button, I only have two options. Volume up to enter TWRP as expected, or it begins cold booting. Guess that got lost in my lengthy message above:
So... I'm still having to reboot from APX mode using nvflash and hold the volume down button. At that point I can either enter TWRP or leave it go and it'll cold boot - no icons
display for fastboot, etc. It just shows:
Platform Pre OS boot configuration...
Cold-booting Linux
And then it will boot into ICS, though found it may just go back into APX mode again. It can take several tries, but it'll finally boot properly.

So unfortunately, no fastboot - only ADB, APX, and Recovery (TWRP) modes available.

Ok well we need a different version of twrp than what your on now I would highly recommend a version older that what your on now.. as the newer twrps are buggy 2.5.5.0 is a solid one... Make sure you get the one for your tablet...as there are a few different versions... Than rename it
Code:
twrp.blob
Make sure you don't rename it twrp.blob.blob as windows is good at doing still stuff like that.....
Move your twrp.blob to the root of your c drive than open a command window as admin and type
Code:
cd /
This will move you to the root of your c drive in your command window than type
Code:
dir
This will list all the files and folder in the root of your c drive make sure you see the twrp.blob if so your ready
Boot your tablet into APX mode bootstrap into nvflash mode and type
Code:
nvflash -r --download 5 twrp.blob
The output of this will look something like this
Code:
Nvflash v1.13.87205 started
[resume mode]
sending file: twrp.blob
- 8165480/8165480 bytes sent
twrp.blob sent successfully
Than
Code:
nvflash -r --go
Then try to enter recovery...

Ok - picked up v2.5.0.0 (don't see a v2.5.5.0 on the TWRP website) and successfully installed the .blob file but... As soon as I hit the volume up button it went to cold boot instead. I remembered with the Prime that for some reason, the TWRP img file format needed to be used when on the AndroidRoot bootloader. So long story short, got the img file installed and I have TWRP 2.5.0.0 running at the moment.
So where to next? And thanks so far

Sorry, I get over wordy (lol)... Yes, I have TWRP 2.5.0.0 installed and was able to get in. I'd already prepared for this - have the unzipped (once) file sitting in my tablet's root folder (/sdcard). Checked and checksum matched so it transferred without errors (used Airdroid, in case wondering).
Took a few extra minutes - wanted double check all was there as I thought. So yes, have the v9.4.3.30 zipfile (containing META files & blob) on tablet's "root" directory. Currently in TWRP v2.5.0.0 and ready to install it (figuring that's the next step)...
Just give me the greenlight, lol

Still here - at this point have the zipfile unzipped once, on the tablet's root directory, and TWRP v2.5.0.0 installed. I assume going to install the zip file via TWRP Install? Tablet's got plenty of battery charge so good to go - just let me know!
Hi All,
I really hope you can help me out. I am a fairly unexperienced user who was actually quite proud that I succesfully managed to install Katkiss 7.1 a few month back (just to give you the impression what a noob i am in this field). All worked fine until yesterday when i wanted to startup my tablet again. It got stuck at the ASUS screen right at the start.
I've tried to hardboot it via the little hole as well as to use the pwr+volume down option to boot. Both end up at the ASUS screen.
I could get into the fastboot screen but when I enter RCK and can see the different options there, the screen becomes unresponsive so I cannot select anything there. I can also not move the 'swipe to unlock' feature, so I cannot use any of the options there.
The following information is shown when i use the pwr+volume down option:
Key driver not found......booting OS
Android cardhu-user bootloader <1.00 e> released by "ww_epad-10.6.1.14.10-20130801" A03
Starting fastboot USB download protocol
I've tried to connect it to my W7 PC. Via explorer the internal and external memory can be seen and entered. I've also connected it to ADB and enter the command Fastboot Devices. This came back with a response of letters and digits. Then i tried to Fastboot –i 0x0B05 flash recovery boot.blob. That also worked. When I rebooted the device via Fastboot reboot, I got stuck in the ASUS screen again. (my best guess was to repeat the steps i've taken to flash it the first time, but perhaps I made the situation only worse...)
I've browsed many topics but since none of the issues I could find exactly match my issue (my biggest problem is i guess not being able to manouvre in the TWRP menu on the tablet), i'm a bit 'scared' to just try out the given answers there as it might do more harm than it will help.
I would be very grateful if you could guide me in how I can get my Tablet to work again (if at all possible)...
Thank you very much in advance,
Paul
You did not do anything terribly wrong - I think - so let's try to fix it.
To help you understand what you are doing I am going to dissect the fastboot command for you:
fastboot - doh, name of the protocol or program you are using, starts the exe
-i 0X0B05 - Asus vendor code, not strictly necessary
flash recovery - what to do, in this case flash something to the recovery partition
boot.blob - name of the file you want to flash to the partition specified above
So in this case you flashed a file called boot.blob to the recovery partition. Since you did not specify the file path to boot.blob (C:\myuser\fastboot\boot.blob) the file has to be in the same directory or file folder as your fastboot executable.
Now, the question is: What's in boot.blob? Is that a compatible recovery? A kernel? Who knows? Fastboot relies on you flashing the correct files, it has no way of checking if the file you specified is a compatible recovery or your utility bill accidentally renamed to boot.blob. The result suggests boot.blob was not exactly a working recovery.....
So check your fastboot directory for a file called boot.blob. Get rid of it.
Then download a fresh copy of TWRP 3.1 or whatever version you prefer as long as it is 2.8.7 or newer.
Place that file in your fastboot directory, unzip it if necessary. It should have .img extension
You can leave the file name as is or change it to something easier to type - that's up to you
Then flash it to your tablet:
fastboot flash recovery <exact file name>
Reboot and check if you can enter recovery
If you can, wipe /data, cache and Dalvik and reboot
If it still does not boot, format data, reflash the rom and gapps and reboot.
If one of the steps don't work come back here and we'll troubleshoot
Good luck
Hi Berndblb,
First of all thank you very much for your ample response! I will try to answer your questions to my best ability.
So in this case you flashed a file called boot.blob to the recovery partition. Since you did not specify the file path to boot.blob (C:\myuser\fastboot\boot.blob) the file has to be in the same directory or file folder as your fastboot executable.

Yes, I've located this file in the same directory on my PC as the ADB software is located. This i've read in one of the instructions.
The boot.blob file i fetched from this location: http://forum.xda-developers.com/tran...rea51-t3049395
it was part of this package: twrp_tf700t_kang_2.8.7.4-signed
It was the same file I used serveral month ago when i loaded the Katkiss Rom. I see now that it was actually written by you!!

The version I currently have is 2.8.7.4 so this should be OK if I read your description, however it does not have the .img extention, it contains this boot.blob file + a META-INF directory. Since this file worked the last time, i renewed it and send it to the tablet via the flash recovery command which indeed renewed my TWRP!
However, the screen is still inresponsive so I cannot move the Slider to accept to continue or keep 'read only' settings. When the screen is locked after some minutes I cannot unlock it due to the same issue. I've tried to place the tablet in the dock with keyboard and mousepad but with no luck....
Based on this, should i try to download a newer version of TWRP (3.1 as you suggested)?
If so, i browsed the forum but could find a download link to install in on my PC, only via the appstore to send it to my Tablet(https://forum.xda-developers.com/showthread.php?t=1797692)
Sorry for being such a pain....
That sliding button can be very sticky. Try holding it for a few seconds and then sliding or just fool around with it until it releases. Could be as easy as that

I'm afraid it's not in this case...even if the screen is unlocked (when i first enter TWRP), i cannot select any of the tabs as my touch is not recognized....
Btw, i upgraded TWRP to the latest version i could find for the TF700 (3.2.1.0) but still the screen is inresponsive to my touch so I cannot select anything.
Do yo have the keyboard dock for your 700? - NP
Hi Nektopoli,
Yes i do have a keyboarddock, but unfortunately this does not work either. There is no mouse cursor visible and the lock/unlock button does not work either.

No, there is no support for the dock or any of its functions in either TWRP or fastboot.
This is very strange and I almost suspect a hardware failure. Maybe your touchscreen died...
Last thing I can think of on the software side is flashing the stock blob in fastboot. That would replace all the original drivers. If the screen is still unresponsive on stock it's gotta be a hardware issue.
Let me find a link on that...
Here are the instructions: https://forum.xda-developers.com/showpost.php?p=72801448&postcount=8
Link to the Asus website is broken again. Get the Asus firmware here: https://www.androidfilehost.com/?fid=817550096634791660
Thanks again for your suggestions!
I do hope it"s a driver failure indeed...I will try this solution as soon as I am back home from my short business trip. I will of course let you know if it worked.
Thanks again,

Are you erasing the recovery partition with the fastboot command [fastboot erase recovery] before you try to flash the TWRP blob with [fastboot -i 0x0B05 flash recovery c:TWRP LOCATION HERE]? - NP
Did you check the md5 of the zip you downloaded? This file has been downloaded multiple times and always was OK. Winrar does not have any business touching the blob. Why is it reporting it corrupted? You are not trying to extract it or something are you?
But you can try searching for "Asus TF700 Firmware" and see if you can find the Asus repository

No, i did not use this command so far.
I assume I should do so before uploading the blob file i used a few months back?(which the first post was based on; finding a solution for the tablet not being able to boot past the ASUS start screen)
This topic evolved into the screen not being responsive in TWRP but perhaps solving the issue mentioned above might resolve this latter issue as well.

1st you need a working TWRP [recovery console] which is what erasing and flashing the recovery partition should give you, once you get a working TWRP you can wipe the rest of the tablet and flash the ROM, SuperSU and GApps. - NP

The tablet is not bricked if you have fastboot. You may have a hardware problem, but we don't know that yet and the only way to find out is to flash the Asus firmware blob in fastboot.
I just downloaded the firmware zip from my Android File Host site and checked the md5 - the file is fine. But here is the link to the Asus repository, took about 30 seconds on Google to find it: https://www.asus.com/us/supportonly/ASUS Transformer Pad Infinity TF700T/HelpDesk_BIOS/
I don't know what you are doing, but you are not following my instructions, so I really do not know how else to help you. There no "drivers' to download or install. You need to flash the stock blob as I described before
One last time:
Download the 10.6.1.14.10 firmware
check the md5 sum to make sure you do not have a corrupt download. If you do not know how to do that, google it. Plenty of instructions out for that
Unzip the file you downloaded
Copy the file called "blob" into your fastboot directory
run the commands I posted one by one
When done your tablet should boot into a JB 4.2 rom. If the touchscreen still does not work you need to replace the LCD/digitizer combo or give it up for dead.

I'm sorry Berndblb, I was really trying to do exactly that what I understood you told me, however i am really a noob on this so have sometimes a hard time to understand.
Since I do not know how to check the md5 sum, i tried your other suggestion which was to google on firmware. However i see now that you meant a ASUS repository (i dit not know what this word repository meant) so i just took the first decription which seemed to match my search query. The result was a ZIP file containing a META INF folder and a blob file, so I thought i got what i needed. I should not have used the word drivers, I meant just firmware.
Again my appologies. I really did not mean to annoy you.

Thank you for the link. This file i could download without any difficulties. However I could not find where the MD5 was stated on this site for the file which i downloaded, nor did i find any .chksum file or anything. I also tried so read the source code of the site, but this is way over my head and could not find anything that matched the MD5 I found of the downloaded file itself.
I would be interested to learn though where I can find the MD5 for this particular file/site when it's not stated like on your own site (I mean https://www.androidfilehost.com/?fid=817550096634791660). Anyway, the MD5 i got for the WW SKU 10.6.1.14.10 download (2nd from above) is a368c6096db38d375dc799273376d804 (I took the ww SKU because that is what my tablet showes when i use power+volume down: ww_epad-10.6.1.14.10-20130801" A03)

Although I could see on my tablet that the blob file was installed (it displayed a blue progress bar) , the end result is still the same, the tablet does not boot but hangs on the ASUS screen you see directly after you power it on. I've waited for approx 30 minutes, but it does not come past it.
