TWRP recovery will not install on ME301T - Transformer TF300T Q&A, Help & Troubleshooting

Hello all.
FIrst, I am not new to this. Just let me get that out in the open. I've done custom ROMs and recoveries on four devices including two HTCs. However I'm new to Asus and this is my first tablet.
So, what is going on is that I have an Asus Memo Pad ME301T. It is rooted, bootloader is unlocked (confirmation appears in upper left corner at boot). However, it will not install the TWRP recovery when I try to push it from my PC. I try to choose the recovery icon on the bootloader, and it shows the fallen android with an error message when it tries to open. I have followed the directions and executed the proper commands from the platform-tools folder in the Android SDK. I thought maybe I could try downloading the BLOB file directly to the device's emulated sdcard and installing it via a terminal command, however I do not know what commands I should use from a terminal emulator. I'm sure it's something simple I'm missing. I am trying to install the TWRP 2.5.0 recovery because it seems to have the highest success rate, and I am currently on the 10.6.1.15.ww stock ROM.
If someone familiar with these tablets could go through the process with me, step by step, one more time (don't just link me to a thread unless it's clear, concise, and exactly what you would do in this situation) or provide the commands so I can try it from the terminal within the tablet, I would appreciate it. When I've had problems in the past it's been something simple most of the time or an extra step I need to do so hopefully one of you can tell me what I'm missing.
Thanks!

So you are trying to install twrp from fastboot ?
What command are you using ?

Exactly. I open a command line on the folder, renamed the file to twrp.blob, and then I I am using the following:
ADB devices
fastboot -i 0x0B05 flash recovery twrp.blob
fastboot -i 0x0B05 reboot
I think the problem is really simple though. I think for some reason, the tablet and the computer are not communicating via fastboot. I.e. the info is not actually getting through the USB cable to the tablet when in fastboot. I have android debugging enabled and all that good stuff. So my assumption is this is a driver issue or an extra step needs done on the tablet to get the communication working. All drivers did install properly according to the PC. Maybe it's even the USB port on the tablet itself and I need to exchange it. But I can transfer files like it's a media device, so I doubt that's it.
Any thoughts?
***UPDATE***I checked settings in SuperuserSU and it turns out I did not have root enabled at boot. Enabled it and it connected to the PC as "fastboot". Commands are still not getting sent to the device. Whenever I try to send the blob, it always says "0 KB" and the device just freezes. Perhaps I need a different command or fastboot on the PC isn't initializing correctly? Or maybe there is a setting on my device that needs tweaked yet?
Thoughts?

I think I know what the problem is. Someone using the TF300T tablet had the exact same problem I'm having. Turned out it was their rooting method. I used KingoROOT despite a few murmurs of it causing issues because I was looking for results quickly not a quality job like I should have been. SuperuserSU has been behaving weirdly, as well as my USB android keyboard and a few other quirks in the OS since I did the root, so it makes sense. I will have to use the KingoROOT app and undo the root, and retry with motochopper. KingoROOT must not have rooted all directories. If that doesn't work, I will probably have to do a full restore to stock settings by re-installing a stock Asus ROM and start fresh.

Did more work and research. I did actually have the improper drivers installed. I installed them from Asus, so that is fixed. But the problem remained. After further research, it came down to version builds and numbers. I am using a version of Asus' firmware that isn't compatible with the operations I'm trying to perform. I am using version 10.6.1.15. TWRP 2.5.0.0 and newer can NOT be installed on any Asus tablet running anything less than 10.6.1.27. There is something about the bootloader, encryption or a security setting that prevents data from being pushed via a fastboot command. So I now have a Christmas project, which is update to a newer version of Asus firmware.
I found my solution here, in a thread filled with people having the exact same issue:
http://forum.xda-developers.com/showthread.php?t=2179874&page=3
And directions for the fix here:

[Q] My Asus TF300T is on stock Android 4.0.3, what to do next?

The darn thing just started nagging me with an update notice that comes back every ten minutes. I read somewhere that updating is going to stop me from doing certain advanced things, so I finally got the last push to go for either CM10 or CleanRom, depending on which one gives me the most advanced and pleasant experience.
But before doing so, it's recommended to get some kind of flash info file or something from it that doesn't come out when upgraded to the latest firmware but does on the old 4.0.3. What would be the best way to go from now on?

Your tablet will say it is unlocked in the upper left part of the screen when The Asus logo appears at boot.

Hi, if your tablet is still on stock 4.0.3 (ICS bootloader), I recommend doing NVflash first
http://forum.xda-developers.com/showthread.php?t=1894867
If you have already updated to JB bootloader it won't work.
It doesn't say Unlocked, so I guess that's why I don't see the USB option when I try to get into Fastboot?
I'm also not able to get ADB commands recognized on my win7x64... Am I doing it wrong? What's the proper method/order of events here? Isn't there a really n00b-proof version of a guide here, or is it something I should write as soon as I get out of this mess and get it working?

Perhaps I'm not really looking in the right location, but the Asus website says I need to choose an operating system and gives me no option to choose. This way I'm not able to download the apk...
Edit:
Tried clicking the links with the tab and it started the download... Device now has an unlocked bootloader. On to the next one...
Edit2:
Ah, now I get it. Pay attention to where that Android SDK stuff is being installed. Mine got installed in the folder I unpacked the installation files! So somewhere 256 folders deep on the Desktop was the right 'adb.exe' file. Make sure the tf300_nvflashpack files are in the same directory and open the command prompt there. After that I got back to the http://androidroot.mobi/t3_nvflash/ website and entered the commands. One moment please, back in a flash!
Edit3:
Now I have 5 files in /mnt/sdcard/AndroidRoot and I uploaded them to my Dropbox. I'm guessing they are the right files...
blob.bin
blob.log
bootloader.ebt
create.bct
recovery.bct
To be sure I uploaded them all.
Copied these files into the SDK folder, along with the other zipped files for nvflash so the nvflash command works to get the other three backup files.
Edit4:
Went on following the guide and checked the video to see if I was really going the right way. Finally I have all files backed up. Goddamn what a journey, but it makes you grow a pair of balls. Now on to the next hurdle, getting a proper ROM, because stock is really getting on my nerves.
So CleanRom, CM10 or Energy ROM? Should I first upgrade to JB? Without or with the popup I'm constantly getting?
Lex,
You have alot of the same questions I do/did, and I have your original post open in another window to respond to all your questions. I'm working on writing a guide for all this stuff so this is rather helpful. If I respond to a question twice, please forgive me as I'm literally just going down the list and answering em as I read em.
In your first post, the file you're referring to is gathered via NVFlash. I haven't used NVFlash yet, but what I understand is that if you use this tool it basically backs up your ICS (4.0.3) bootloader information. The newest firmware change is to Android Jelly Bean (4.1.1) and that re-locks your bootloader. Once you go to JB, you cannot go back. So this servers as a backup (again, this is just how I interpret the information from their website. I don't know how correct my interpretations are, and have actually opened a thread to ask for clarification about this program).
For the drivers, all I did was download the android SDK and install the 'android tools' and "extra - google drivers' from the list. My laptop was just recently wiped-out so I have no prior drivers installed, nor have I connected my tablet to my computer yet (just got a replacement tablet last weekend). I didn't use the universal driver or any other add-ons. Just use the SDK, it will install drivers, and then it will detect your device. I verified this by typing "adb devices" in command prompt and it detected the serial # of my device.
Within that same post, you had some confusion about ADB. It's just an executable, and you have to use the command prompt window from whichever directory it is installed to. So once you unzip the Android SDK or wherever you installed ADB to, use the command line commands "cd directory/where/adb/is/installed" to navigate to it, or use shift + right click within that folder and it will have an option to "open command prompt here" with admin privileges. That makes life a bit easier. Other people also install their SDK to C:\android\SDK or something similar, so it's less to type.
In order to determine if your bootloader is unlocked, look at your tablet in the top left hand corner when it boots up. It will say "Device is unlocked" and list a bunch of numbers (which if I remember correctly would just be the firmware information). Your device will not be unlocked until you actually download the unlock tool from asus' website and push the file via adb to your tablet and install it. That is, you have to take a very specific, very advanced overt action to unlock it. Nothing else and no one else can do it for you nor can it be done accidentally.
Next post (#8 in the thread): You are correct that fastboot will not show unless you are unlocked. I just verified this on my not-unlocked, not-rooted new tablet, and cannot enter fastboot mode. Your ADB commands wont work if your drivers are not correctly installed.
Post #10: You have to select "Android" under the OS drop-down box to find the unlocker app. As for the location of the ADB.exe, mine was found in this subfolder within the android SDK: <whereveryouunzippedit>\Android SDK x86_64\adt-bundle-windows-x86_64\sdk\platform-tools
That folder contained the correct (and I think only) adb.exe I needed.
For your last part, I think you should try out a number of ROM's to see which you like best. I've tried all the major ones (CM9, CM10, CleanRom, Hydro, Blackbean, and some of the stock rooted/de-odexed) ROMs and used Blackbean for the longest time because of how slick it looks (all black) and how easy it is on my eyes.
Make sure you document the steps you took so you can remember them in the future. I'm working on writing a guide right now and documenting my steps to go from a stock, locked, and not-rooted tablet to a rooted unlocked and custom flash tablet.
I really hope I was able to clarify some things. I am by NO MEANS an expert but I've spent many hours experimenting and think that I wish I had someone to answer my questions when I was first learning, rather than learning by mistake.
Hopefully this helps,

Hi, I use Energy rom which I find pretty good, you will need to update to JB first as Energy, CM10 & Clean rom are all JB bootloader compliant. My tab came with JB pre installed so not sure what the best way to update is but would assume since you still have stock recovery would be with OTA update (popup notice). Here is a guide to update to JB but I think this is if you have already installed a custom recovery as it looks like you flash back to stock recovery first, thats why I think if your getting update notice and still have stock recovery, go with that.
http://forum.xda-developers.com/showthread.php?t=1845377
Once you have updated to JB stock here is a guide to install custom recovery (CWM or TWRP), root & install custom roms.

Same goes for you! Tomorrow I will be trying as much ROMS as I can to see which one suits me best. Also repeating this process is the best way to learn something and since I'm unbrickable, I am going to flash the hell out of it for a few days. I'll try to post my steps and findings here so I (and perhaps others with the same trouble) can benefit from it in the future.
Also I think when you update to JB your bootloader will be locked again (new bootloader), the above guide on root, customs roms also has info and links on unlocking JB bootloader. Glad I could help, have fun :good:

It's upgrading now. Of course I forgot I lost root with the last OTA update and I forgot to make sure I rooted the thing so it was able to use the rootkeeper after upgrading to JB. I hope there is some documentation on rooting JB, because at the time this all happened root was not possible yet. It's past 1 AM over here, so I guess it's best to save this quest for later when I had some sleep.
Edit:
Just for kicks I tried 'Root Checker' and it said 'no root'. Then I saw 'Rootkeeper' was installed. Opened it up, tapped the restore button... Device rooted! Guess my memory is really failing big time... One down, # to go.
Edit2:
Installed TWRP:
Just downloaded the .blob from their website and
put it in the platform-tools folder.
Then renamed it to TWRP.blob.
Turned off tablet,
plugged in USB cable in the tablet ONLY,
hold volumeDown button,
plug into laptop holding button,
waiting...
choose USB logo,
open cmd-line in the platform-tools folder,
run command: "fastboot -i 0x0B05 flash recovery twrp.blob"
waiting...
Done. Let's see if it works...
Edit3:
At first I didn't understand how to get into TWRP (DOH!),
Hold volDown, power on, choose RCK.
Edit4:
Been having a fight with TWRP when I try to install CM10.1 (latest nightly: 20130121). Gives me an error status 7 or something...
Code:
Verifying update package...
assert failed: getprop("ro.product.device") == "tf300t" ||
getprop("ro.build.product") == "tf300t"
E:Error in /external_sdcard/CROMS/****.zip
(Status 7)
Error flashing zip ' /external_sdcard/CROMS/****.zip'
Of course, ****.zip is a long filename I didn't want to type completely here.
Will try to figure out whats wrong later today, first I'm going to try restoring the backup I made earlier, just to see how a complete backup works when the tablet is wiped back to factory settings.
Edit5:
The backup stuff is really cool! My tablet is back the way it was even though I wiped it completely!
Back to the ROM rumble... baked_tf300t_blackbean-6_jb-bl_b6.zip gives me the same error. Starting to get annoyed again... Let's try something different, CleanROM. Download is taking ages... I'm restoring again, so I can use the tablet for the rest of the day. As soon as I feel like it I will try again, for now I'm giving it 'the finger'.
Edit6:
Cleanrom is installing now. I guess CM (baked is CM based right?) was causing some trouble...
Done installing...
Wipe Cache/Dalvik...
Reboot...
Android is upgrading...
Might need to choose the small font, my screen is really clogged up with stuff. Didn't expect to keep my settings etc., thought it would be completely wiped. I'm going to restore and then reinstall with the highest DPI setting first, then I'll wander around the rom to check if I like it.
Edit7:
I think I'll stick with this one for a few days, runs fine if you ask me, maybe take the time to finally update my Galaxy Nexus to CM...

Wingray - Internal Storage has been wiped, and I'm out of my depth.

My friend gave me his bricked Xoom, which I accepted as a challenge, because I've been rooting and flashing my phones for years, but after 10+ hours of searching in the last couple weeks, I have been unable to locate coherent information on how to un-brick a Xoom that has had its internal storage wiped. My friend was trying to do a thorough wipe, and he succeeded in that, if nothing else.
My first obstacle was finding a driver, because Motorola Device Manager wants nothing to do with the Xoom, and whenever I finally found a link to a driver, it was at developer.motorola.com, and there apparently is no such domain, because every link takes me straight to motorola.com/us/home, where all that's waiting for me is the bloody Moto Device Manager.
The only post I found that seemed like it was aiming at where I want to get is at http://forum.xda-developers.com/showthread.php?t=2317986, but I ran into problems that weren't foreseen by the author, and I haven't been able to find anything pertinent that doesn't direct me to developer.motorola.com again.
The Xoom has TWRP v.2.6.3.0(runandhide05 edition) for a recovery; and I'm aware that there is a 3.3 version, but I'm nervous about flashing a recovery update when there is no OS on the tablet. It was running EOS 4.2.2 I think, before the bricking.
According to the guide I found, I put TWRP into adb sideload and was able to get my PC to communicate by installing a universal adb driver from https://github.com/koush/UniversalAdbDriver, so in my system Device Manager, the Xoom is listed as a GOOGLE GALAXY NEXUS ADB INTERFACE.
When TWRP is in adb sideload, I can interface with the Xoom via cmd.exe, but when I try to push a ROM, I keep getting an error on TWRP:
Code:
file_getprop:failed to stat "/system/build.prop" no such file or directory
...whatever that means. Another thing that kind of worries me is that when I type adb devices, it shows my device as 1234567890ABCDEF, which doesn't seem right.
I have yet to try fastboot, because I don't know what .img files I need to flash, and I don't think blind flashing is going to make things any better.
I think I have all the pieces, SDK and JDK are installed and updated, and I have the stock rom (HWI69.zip). I reckon if I can get the stock 3.x OS running, I'll have a jumping-off point, and be good to go; the process from there is well-documented.
Can anyone give me a nudge in the right direction, please?
~Fake
Status 7 errors
Those are usually caused by either a not-so-compatible recovery image. Some TWRP versions have issues with certain ROMs. I had this happen to me with my Asus TF300, ended up trying a few different TWRP versions before I found one that worked right.
The other cause is an invalid ROM image, if you open the ROM.zip file on your PC, does it look ok, did you check its MD5sum???
Were you able to wipe the Xoom from TWRP without error???
-Mike
When I got it, it had been wiped completely, so I presume that twrp wiped okay.
Not sure about the MD5sum, just that twrp didn't find one during the adb installation. Do you think flashing cwm might help?.
I got it worked out, opened up the HWI69.zip stock image and fastboot flashed the individual .img files, and it booted right up. Thanks!

No operating system found.

Totally new to xda forum, and pretty much a noob. Nexus 5 (US model). I was trying to unroot my Nexus 5. I bought it from a friend who had rooted it using TWRP, and it was running CM. Anyway, I managed to completely wipe the operating system ... completely. It will boot using the power/volume down configuration, but when I try to start the phone, it says, "No operating system found." All the threads I have been reading (yes, I have done a lot of reading), assume a couple of things: 1) that the phone can get into Settings/Developer Mode; and, 2) that my PC finds my phone when I plug it in. I have tried the adb and fastboot driver downloads, and wound up with some weird app that was almost impossible to uninstall off my PC. Ten-something or other. I tried doing the flash-all thing, but got a message that there was no such command. Can anyone help me, either directly, or by links to what I need? Once again, I have no operating system on this phone. Thanks.

I second that recommendation. With a caveat. Wugfresh's Nexus Root Toolkit is a superb piece of programming which should enable you to set up your PC with all the necessary drivers and also let you specify the ROM you want to install, download it for you, and install it. You should obviously take the latest MMB29V.
But...
I see that you've done a lot of reading, and I understand that Android is initlally hard to grasp, but please don't (a) think you'll never understand it and (b) think that NRT is the answer to all your problems - it isn't. There are lots of reports of people saying "NRT has broken my phone" either because the've used it incorrectly or because they've used it before Wug has had a chance to update it to cater for all the latest tweaks that Google have introduced (particularly on Marshmallow root). If you're careful, set up your drivers properly, and install the correct version for your phone (Hammerhead MMB29V), NRT should give you back a working phone. But after that, read more, and investigate manual update methods, which are particularly useful for installing the monthly security updates without losing your data or waiting for the OTA (over-the-air) rollout from Google.

I'm in the fastboot mode, and I can get into TWRP, but I can't get my PC to recognize the phone. I've followed every rabbit trail I can find, but the phone doesn't show up. The USB ports are fine, and all the USB drivers are up to date. This is what is on my phone screen:

BOOTLOADER VERSION - HHZ12k
The rest is serial number and so forth. I can get into TWRP, but can't ADB Sideload because the phone is not showing up. Giving me an error 43.

Totally new to xda forum, and pretty much a noob. Nexus 5 (US model). I was trying to unroot my Nexus 5. I bought it from a friend who had rooted it using TWRP, and it was running CM. Anyway, I managed to completely wipe the operating system ... completely. It will boot using the power/volume down configuration, but when I try to start the phone, it says, "No operating system found." All the threads I have been reading (yes, I have done a lot of reading), assume a couple of things: 1) that the phone can get into Settings/Developer Mode; and, 2) that my PC finds my phone when I plug it in. I have tried the adb and fastboot driver downloads, and wound up with some weird app that was almost impossible to uninstall off my PC. Ten-something or other. I tried doing the flash-all thing, but got a message that there was no such command. Can anyone help me, either directly, or by links to what I need? Once again, I have no operating system on this phone. Thanks.

I'm in the fastboot mode, and I can get into TWRP, but I can't get my PC to recognize the phone. I've followed every rabbit trail I can find, but the phone doesn't show up. The USB ports are fine, and all the USB drivers are up to date. This is what is on my phone screen:
FASTBOOT MODE
PRODUCT NAME - hammerhead
VARIANT - hammerhead D820(E) 32GB
HW VERSION - rev. 11
BOOTLOADER VERSION - HHZ12k
The rest is serial number and so forth. I can get into TWRP, but can't ADB Sideload because the phone is not showing up. Giving me an error 43.

I don't disagree with the NRT suggestion but am confused. Sorry if I'm missing something obvious. When you are in the bootloader, do you get a cmd response from "fastboot devices" (no quotes in the command)? ADB doesn't work from the bootloader as you probably know, but since you identify as a noob, thought I'd throw it out there. You can flash the system using fastboot commands if your PC recognizes (part of the confusion) the device in fastboot. If not, then you do need to get the drivers set up. If you just need adb/fastboot drivers, I recommend this which I used recently when NRT didn't seem to have the SDK version I needed for my N9 to sideload the latest OTA. Since it installs at the system level, you can place flashable files at the root of C rather than in a specific platform-tools folder. I'm on Windows 10; don't know if that makes any difference for this minimal install. As far as the flash-all. bat not working, that's not uncommon; the files can be extracted and flashed separately.

Won't upgrade Factory Software, Wont enter recovery. Hangs on boot

First off, my tablet isn't bricked. I can boot it up fine. But when I try to install the factory downloaded software it just hangs on boot indefinitely. Similar things happens if I try to enter recovery. It goes fine until I have to press Volume ^, then it just freezes and I have to hold down the power key for 10 seconds. I've searched around and all I can find is threads from people stuck in a boot loop. Any help appreciated
A little more information. This tablet has been sitting for a while because it was such a disappointment. Before I decided I was fed up with it, it looks like I unlocked and rooted it. Iooks like I may have also tried to install Clockwork Mod on it. Trying to fix it has reminded me of why I stopped using it in favor of my nexus 7. The UI feels like it was designed specifically to make people not want to use tablets.
The problem probably is the How.
And unfortunately you don't give us any info on that.
Why do want to flash stock if you hate it so much?
If you have CM on there you should have a custom recovery installed.
Which one?
What's the bootloader version?
And lastly, you can boot into fastboot mode? The screen with the 3 icons?
If yes, almost anything is fixable.
But you need to give us more info.

@berndblb. Thanks for the reply. It has been so long since I did anything with this tablet that I completely forgot what I had been doing since the last time I was trying to make up for it deficiencies. I seem to have gotten everything sorted. Uninstalled then reinstalled Busybox & Supersu. Then used TWRP's apk to re-install custom recovery 3.0. Install said it failed, but when I booted into the bootloader I could actually make a selection, instead of it hanging indefinitely while it tried to load the recovery. Win for me I guess. Finally able to make a backup which always feels good. The whole point of this is to install a custom ROM so that my tablet becomes more than a really expensive coffee table decoration.
The current install on my device is. Android 4.1.1, Kernel 3.1.1, & build 10.4.4.23-20121171
Any suggestions on moving forward and a recommendation on a clean ROM would be appreciated. But I can always take the time to read as well.

The first thing you should have done is upgrade your bootloader to the latest version. I would not actually use TWRP 3.0 for anything at this point if I were you. I have no idea if TWRP 3.0 works with that ancient JB 4.1 BL you got there, but I would not chance it. As a matter of fact, since you have to flash either stock rom or just the bootloader (and for both you use your recovery) I would highly recommend you flash an older TWRP version that is compatible with your BL. That combo - BL and recovery - is nothing you want to screw around with. You should go back to TWRP 2.4.1 or so.
TWRP Manager forced the latest TWRP version (developed for MM roms) on you and that's why I hate these apps! They do not check for compatibility at all....The proper way to flash a recovery is in fastboot and in fastboot only.
so I am going to give you a bunch of links and a general plan of attack, but you will have to do a fair share of reading.
First things is: Get fastboot working on your PC!!!!!! The first part of this guide I wrote way back tells you how: http://forum.xda-developers.com/showthread.php?t=2688891
Once you got that working flash TWRP 2.4.1 - instructions on how to are in the same thread. Reboot the tablet, then boot into TWRP.
Now flash the latest bootloader (Packaged with a slightly younger TWRP version from here: http://forum.xda-developers.com/transformer-tf700/general/firmware-10-6-14-10-twrp-t2867157
Reboot the tablet, then boot back into TWRP.
Now you again need to update your recovery to a version you can use with a current rom. I'd recommend this baby and it comes in a zip you can flash in your current recovery: http://forum.xda-developers.com/tra...overy-kang-twrp-tf700t-2-8-x-xarea51-t3049395
Flash the Kang recovery, then reboot and boot back into TWRP.
Format your data partition in TWRP. It takes an hour or so but it does a great job of leaving you with a clean slate for the new rom and is required before you flash a major change (which you are doing in any case).
Now you are ready to flash a rom.
I am going to recommend a really old one and a really new one. There are plenty of others to choose from in the Development section, but none of them is still under active development.
CROMi-X Resurrected. Based on Asus stock anno JB 4.2.1 but modded and fine tuned to the gills. LMK still puts out an update now and then, but those are more fine tunings of the fine tuning. Very slight changes - nothing major is going to happen here anymore. But it's a very stable and well working rom for those that actually like the Asus interface. http://forum.xda-developers.com/tra...pment/cromi-x-5-4-resurrected-tweaks-t3273515
KatshMallow by Timudru. Yeah, Android MarshMallow for the TF700. Most Android users are still dreaming about MM and you can rock it on this ancient machine. And it's a beauty, just absolutely unbelievable what Tim has cooked up for this hardware. Trust me! Fantastic rom! http://forum.xda-developers.com/transformer-tf700/development/rom-t3282166
For both of them you should convert your data partition to f2fs which you can do in recovery. Instructions are here: http://forum.xda-developers.com/tra.../guide-convert-data-to-f2fs-twrp-2-8-t3073471
Actually, for CROMI-X Resurrected you don't have to do this - it's build into the rom installer.
You could try to short cut all this and just flash a new bootloader/recovery combo in your current TWRP 3.0. Maybe it works. Maybe it hardbricks your tablet. Nothing worse than trying to do something substantial (like flashing a bootloader) in an incompatible recovery....
Ok, now I shut up and let you read.
Have fun!
@berndblb thank you so much. I really appreciate you taking the time to help me out with this. This isn't my first time to the rodeo, but I'm def not ever going to ride in the pros. Trying to install a custom rom an this tablet has really shown my how much I don't know. I'm going to follow your instructions. I will get back later and let you know how it goes.

I could tell. That's why you got the self-help version
I know how it feels. After 3 years I am fairly proficient on this device. But I still felt like a total n00b when I got the first Nexus! :cyclops:
So much of this stuff is so device specific... takes a while to sink your teeth into.
Enjoy.

I have fast boot running and back-checked it via the fastboot devices. I downloaded twrp-2.4.1.0-tf700t.blob. the tried to load it. I keep getting a FAILED( command write failed (Invalid Argument)). Any thoughts
Plenty. Unfortunately Windows is very finicky with fastboot...
If push comes to shove you may want to try a Linux live CD or distribution and I'll add a link later, but try this first: and try "fastboot reboot" to see if you can execute anything.
Sure you got the original cable?
Reboot pc and tablet
Try a different USB port
Connect the tablet booted into fastboot and check the entry in Device Manager for problems.
Now we're getting desperate....
Boot into Android, check if you have a data connection by push/pulling a small file which you put into the same directory.
adb devices
adb push filename /sdcard/
adb pull /sdcard/filename
adb reboot-bootloader
Then see if you can do anything in fastboot.

Got fastboot running properly on my work computer with windows 7. I've gotten everything installed up to formatting the data partition. Doing that now. Super stressful & hard not to mess with it while it makes its way through a hour long process.
What did the trick to get fastboot working?

Looks like I got it sorted. Decided on going with the KatKiss rom. And the performance is night and day. Thanks so much for all your help. Next time I will probably do more reading before I try anything more... But then again I tell myself I will read the instructions before I start assembling ikea furniture & never do. So only time will tell. Anyway. Thanks again.

Installing it on a different computer. This one runs windows 7. My laptop runs windows 8.1, could be as simple as that. But who knows.

bootloop - question on how to proceed

I sold my tf700 to a friend, and let him know: Do not factory reset through the Android settings. Well, He passed it on to someone else, and forgot to mention this. So, that whole TWRP bootloop scenario exists. Dug through forums, found a post where someone had made some file that resets the boot process to not go immediately to TWRP or something, IIRC, but regardless, I've got a custom-made solution, and even wrote a batch file to automate the thing (given the amount of time you have the TWRP screen before it reboots) much like the OP had.
Here's the problem: my desktop doesn't recognize the usb device when I plug in to windows. IIRC, I'd always had some kinda issue with that version of TWRP, but I never addressed that, and that fell by the wayside apparently. I don't have time to sanitize my PC and re-establish the ASUS driver environment or other advanced trickery or whatever, and I just sold my laptop prior to trying on that. My question to you fine folks is this: If I were to install Ubuntu or some other Linux-based environment, would my odds increase in terms of being able to coax TWRP to be recognized so I can flash this tiny little file over and get the thing back running? Apparently windows just doesn't want to, and short of being able to put a newer TWRP on the device, I've got to establish a usb connection somehow.
TIA :good:

Well yes and no.
Linux works much better with adb/fastboot, but if it it easier to install Linux and get it working if you have never used it compared to getting Windows drivers working - idk....

I figured that would probably be the case. Now, it's been several years since I've used Linux (Ubuntu Feisty Fawn was the last time I used Linux, and that was just to hack a first gen Xbox), but i'm a command-line based OS guy from the days of old, so I oughta be okay. I'm sure one of the various and sundry tutorials here on xda will help should I get stuck.
So, that being said, I guess I just need to install a distro and grab some adb/fastboot drivers for Linux? Or is that all built in? Is the command line interface sufficient, or will I need some GUI like xwindows (sorry if my info is horribly dated, lol.)
I'd probably better do some reading.

I cam across this live distro recently and the dev included the tools needed for adb fastboot. It works great! https://forum.xda-developers.com/an.../live-iso-adb-fastboot-driver-issues-t3526755
There also several Puppy Linux distros out there which may be interesting since they offer persistent mode already but afaik you have to download the adb fastboot binaries yourself. But that's it - no drivers needed.
With those installed you just need as terminal window. No other gui necessary

This is just the tip I needed. Big thanks!
Well, i assembled the troops- universal naked driver and minimal adb/fastboot on a fresh win 8.1 install. Bootit.ko file in my adb folder. Opened adb, plugged in tablet. Twrp starts. Hear the USB plug in noise, so adb is ready. Adb devices command, shows up recovery like it should. I then run a batch command to automate:
adb push bootit.ko /sdcard/
adb shell insmod /sdcard/bootit.ko
... as per the directions. I get this in response:
adb: error: connect failed: protocol fault <couldn't read status>: no error
on the first command, and 'no device found' on the second.
Now what?
Edit: nevermind. Added 'adb devices' to the batch file and it did it fast as anything. Lol.
New kink: adb command succeeded and i got fastboot access. Formatted 'misc' partition and rebooted-- still with the bootloop. I can still access fastboot, but that's it. Twrp always restarts. So, did SWIM bork the recovery partition too? Wondering if I should try re-flashing twrp, or downloading the original ASUS blob file and restarting from square one?
Edit:
Got impatient, started trying things. Links found thru the forums pointing to original ASUS rom blob are all broken, so i settled for starting with twrp. Downloaded freshest version from twrp.me compatible with the device and flashed it-- same result upon attempting to open twrp.
Took a break. Thought about it, and decided to fastboot erase recovery, and try flashing twrp again. Probably not a great idea... Now I get
Sending 'staging' <7210 kb>...
FAILED <data transfer failure (unknown error)>
So I guess there's a step after erasing to re-init the partition or something?
Just a note to anyone lurking - don't do stuff if you're only half-informed. You can be stupid and impatient like me and have broken stuff.
Impatience is a very bad advisor...
As long as you have fastboot you should be ok. Asus seems to have messed with their website again or they finally took the support pages down permanently.
I have a copy on my server and can upload it tonight.

Debate my breath? Well, my breath reeks of Marijuana... I think it's a liberal.

Just a question: since I'll be repopulating all the partitions with the stock blob, does that affect my unlocked bootloader, or is it gonna be straight up manufacturer reset? I'm sure that's covered in the threads that address the 'buster99' process, but I need to go locate the thread. I didn't fully digest the thread as i'd yet to find the blob I could d/l, until you hooked it up. ?
No, you cannot relocate the bootloader. Flash away

Ugh, corrupt archive. ? trying to download from a different server this time.
Edit: same results w/new download. Repairing the archive didn't help either.
Asus, ya'll are killing me! Every link on the interweb linking to a TF700 firmware is broken, and all that can be found are for the 700kl.
Final update:
Found a valid download link for 10.6.1.14.8. Had some difficulties with it (revived the post on the buster99 process) -- followed as written, and had a fail on the last process <invalid state>. Being super impatient (mentioned *that* before, lol), I decided to try and reestablish twrp, as that was the original issue. That took! Flashed 3.0.0-1 (iirc), was able to open twrp, but couldn't mount system or anything. So I formatted the crap out of all partitions, converted /data to f2fs, and was able to successfully flash katkiss nougatella. Wiped the caches, rebooted, and I'm golden! 3 months later, and it finally works.
Moral of the story: don't sell rooted devices to ppl who don't understand what that entails. You can tell a person till ur blue in the face, NO FACTORY WIPE VIA ANDROID -- Odds are, they'll forget. Worked out for me in the long run (took back the 700 and gave a 201 as replacement), but i was never sure I'd come out clean on the other end.
I have similar problem, i can't even go to bootloader.
Just keep bootlooping. Is there any chance of reviving my tf700t?
If yes please advice me step by step process to do that.
Thanks

Thanks you already help on other thread.
It's a long story how this happened.
By the way I was running nougtell version don't remember as it happened in January.
I wanted to transfer some video files on my usb 2tb hard drive, so I did usb otg connection to my tab, i did this thing before and I use es file explorer to do the transfer, few occasions es file hang or whole tablet hang so I have to restart. But in January when this thing happened it just went into bootlooping i can go to fastboot but not recovery or android.
Then I search on many thread i couldn't find any working solution.
My cable was not detecting tab so I couldn't able to push recovery., But the same cable was ok for charging.
Then I bought new cable from eBay it took around a month to arrive.
But in mean time being impatient i tried data wipe from bootloader.
Then even i couldn't able to bootloader after that.
I know being impatient with doing something like this is not good you have to suffer.
Bootloader was latest version .14 at the end and recovery was 3.0.1
Using nogtella rom
Thanks
