Guide to fix TWRP or CWM bootloop

This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
Long story, short:
For some reasons, seems like the WIPE command from TWRP and CWM recovery screw the partitions.
No partitions or microSD card can be mounted.
The tablet is now booting only in recovery mode or in fastboot mode (the screen with three icons - RTK, Android and WIPE) instead of Android.
IMPORTANT:
If your tablet reboot in fastboot mode DONT WIPE IT AGAIN! Just skip step 4.
First of all, MAKE SURE YOR BATTERY IS CHARGED!
Recharge your tablet for at least two hours.During the flashing process the tablet doesn`t charge.
Use the original Asus USB cable that came with the tablet or a high quality replacement cable. Cheap cables can and will cause problems.
Use a laptop or desktop with known good USB ports. If you have problems, try a diferent computer, some USB chips can cause troubles.
Disable the antivirus or screensaver, sleep etc...
1.Download these files:
from ASUS website: http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300TG/#support
Drivers&Tools, on the OS tab select Android
click on Utilities and download latest version of ASUS PC Sync (you will need this for drivers)
click on Firmware and download the lastest available (you will need this for BLOB file)
Minimal ADB and Fastboot: http://d-h.st/gbx
install ASUS PC Sync and Minimal ADB and Fastboot (on fastboot installer check the box that make a shortcut to desktop)
unzip the firmware file downloaded from ASUS site
you will get a second zip file, unzip this one too
the folder unzipped from the second one contain a file called blob
copy or move the folder to the root of your drive C: or D: or whatever drive letter you have
2.Installing drivers:
connect your tablet to PC
you will get a message about Windows couldnt find driver bla...bla, ignore it and keep your tablet plugged
IMPORTANT: even if you previously installed ASUS PC Sync or other drivers and Windows recognize your tablet, you still need to change the driver.
right-click on My Computer-Properties and click Device Manager
find the Asus Android device - should be with an exclamation mark on it (the driver is not installed sign)
right-click on it and choose:
Update Driver Software..., Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Have disk, Browse
go to C:\Program Files or Program Files (x86), ASUS, ASUS Android USB Drivers, Android and select android_winusb.inf
Asus Android Composite ADB interface will appear in the list of device drivers - don`t hit next yet!
uncheck Show Compatible Hardware and select Asus Android Bootloader Interface from the list, now hit next
3.ADB mode:
open Minimal ADB and Fastboot from desktop - from this point, keep it open
type: adb devices - and you should see some numbers under the List of device attached - thats your tablet
if you can`t see the tablet, try this command: adb start-server
4.Booting to "fastboot":
there are two ways to do this:
a) from adb window type: adb reboot bootloader
or
b) reset and hold vol-down (didn`t work for me, but maybe will work for someone else)
the three icons will appear on screen - NOW YOU ARE IN FASTBOOT MODE
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob
the credits for this part goes to buster99. He is the one who figured out the right commands for formatting partitions and flashing back the OS
here is his post: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
here we go, one at the time in adb window:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system x:\your blob folder\blob (here you enter the path to your blob file, must end with blob, to point at the file)
fastboot -i 0x0B05 reboot
THE FLASH SYSTEM COMMAND WILL TAKE SOME TIME
be pacient and wait until the progress bar is 100% full on the tablet and you get the command prompt back in the adb window.
After reboot, the Android is back on.
Cheers and good luck!!

A big thank you alexhosu,
several months ago that my tablet was blocked, but I still kept hope
a solution would be found. I'm really happy for you and thank you again for sharing.
Long live XDA

me too
Thanks from me too; was enjoying 5.0 (timduru) on my TF300 when I went to upgrade and idiotically managed to get into a TWRP bootloop(interrupted a format of \data and then used 'wipe' from the boot screen by mistake...)
Your solution has saved my tablet
Am now carefully reinstalling Katkiss

Thanks
This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again

Followed the instructions.. Worked well, but getting error 963 when installing/updating anything in Play Store. Seems to be related to storage permissions. Some users are suggesting using format instead of erase. What's the difference? Could that help.
I did factory reset, reflashed and used fix permissions in TWRP but no luck...

Big thanks from me.
I killed my tablet with an accidental restore to factory defaults while in cm12, an got stuck in an endless bootloader boot loop.
my tablet came back too life at the end of section 4 after adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3.
although getting adb to talk to the tablet was a fluke.
I just kept trying to send "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" while the tablet was loading (boot looping)

6 months of believing my tablet was dead, after letting CM12 do its own update thing, and now, thanks to the above instructions, I'm back online and its working with the stock rom.
Thank you so much for this. No idea why I couldn't find these instructions before, then I just gave up, back in business now!

Thanks a lot for your guide, this is what helped me fortunately unbrick my device, i was stuck in a boot loop with a broken recovery

Another tablet saved. Know your work is appreciated.

i have the same problem, the system doesn't pass the ASUS logo, i tired to log into fastboot (reset + volume down) and i was able to see the three icons but adb doesn't recognize my device. i see the drivers are correctly installed but no working adb. Any help is highly appreciated.

Did you try entering "fastboot devices" or just "adb devices"? adb wont find your device in the bootloader, but using fastboot commands should unless it truly is not connecting for some reason.

I would try moving the blob to the root of the C drive and try the 7th command "fastboot -i 0x0B05 flash system C:\blob" just to make sure sometime of file permission type issue isn't happening on the pc side. Other than that the only kind of issue I think it could be would have to be the connection with the drivers, although if erasing the partition's works fine, I don't really see what could be going on.

I followed all the steps and delete, but when loading the file update.blob I get this error:
C: \ Users \ mikel> C: \ Users \ mikel \ Android \ android-sdk \ platform-tools \ fastboot flash system update.blob
error: can not load 'update.blob'
Can someone help me out?

Hey, I know that I'm a couple years late on this. But, I was just given a Asus Transformer TF300T, and attempted to install the Kisskat custom rom. I unlocked the device with little issues. Rooted with little issues. But when it came to flashing the rom. I get his error saying that "no MD5 file found" and holds it there for a couple of minutes. Then gives me the failed install. My only option is to boot into recovery and restore the stock JB 4.2. If you could point me in the right direction, I would greatly appreciate it. I've searched the forum for someone with a similar issue, and couldn't find it. I hope that I'm not alone on this one. It would kill me to be stuck with the stock rom.

Hi i made a format data from TWRP recovery, and now i am in a recovery loop and got error of mount partitions, i can access to recovery and the screen with 3 icons, but when i plug to my pc it shows as uknown usb, i install the drivers but dosent reconose as a fastboot device, in minimal adb when i write fastboot devices the result is empty pleace help me.

Muito obrigado!
I know this must seem odd, being such an old thread and all but, after several years adding apps and changing ROMs on my wife's TF300T (my gift!) only these past weeks I had the need to search for help, after installing nougatella 7.1, which I did with success, only to stumble on endless logo loops and loading processes without conclusion. Don't get me wrong, the ROM looks great and it wasn't that hard to install but, after two weeks or so, gave me this problem and after correcting it and installing again the ROM, I got in trouble again...
After some five hours googling and trying different stuff, I finally found this thread and twenty minutes ago (around 2:AM) my ASUS returned to its (Jellybean) life!
Alexhosu, thank you so very much for such a detailed, yet easy to follow guide and, if you happen to come to Portugal on vacation and visit Setúbal, I'll have a bottle of Moscatel waiting for you!
Many thanks to Droidbound (who got me off the hook the first time the tablet went nuts!), and also Kevinthefixer, Gtanner00 and some other very inteligent, patient and thoughtful people, and all the guys who shared their difficulties and in a way helped me find the people with the fix.
For anyone interested in trying this method, I would say that it's paramount that you should stick exactly with what is asked and should pay real atention to what is the correct ROM update to download and use. If anyone needs help with translation to Portuguese, just say so.
Again, thank you so much for this!

Thanks for your help :good: and I'm sorry for my basic English, but here is another tablet saved. Your instructions were clear and my tablet is working.
I hope this information helps, based in the next link (user sszyman): https://forum.xda-developers.com/showthread.php?t=2275035&page=9
in which he recommends using the following commands too:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p2
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p8
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p1
With these commands and "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" I was able to solve my Bootloop problem.
Honestly I don't know which of the commands worked, I used all several times.

Fastboot TWRP Flash Recovery "error: out of memory" in cmd

Hey, and thank you all here on the forums for all the guides and helpful information.
I am completely new at android rooting, flashing and all that comes with this, though I've read up quite a bit.
Now, my tablet is running the 4.2.1 build "JOP40D.WW_epad-10.6.1.14.10-20130801" which i've found can not be rooted in certain ways, so I went for the fastboot.
I've made sure everything was as should be, far as I can tell from what I've read here:
Tablet prepared:unlocked, usb debugging checked
adb and fastboot ready
correct drivers
latest twrp blow(openrecovery-twrp-2.6.3.2-tf700t.blob)
Then, as I put in the final command "fastboot -i 0x0B05 flash recovery twrp.blob" I get the message "error: out of memory" and the fastboot.exe crashed.
What could be causing this? Don't really want to try over again since I have no idea what I might be doing wrong and I really don't want to end up with the hassle of a bricked tablet.
Could it be an issue with the twrp version, and its compatibility with the tablet?
There is no lack of available memory on my computer, and there shouldn't be problems with the tablet's ROM or RAM, as it runs fine except for the obvious problem this tablet has. Previous to unlocking it was wiped and reset to stock 4.2.1 Jelly Bean with the .10 build.
The CMD window looks like this:
"
C:\users\Hbryne.Hbryne-PC>fastboot devices
015d2d431f240415 fastboot
C:\users\Hbryne.Hbryne-PC>cd c:\android-adb
c:\android-adb>fastboot -i 0x0B05 flash recovery twrp.blob
error: out of memory
"
Thanks in advance for any helpful reply!

It looks as if you ran the 'fastboot devices' command from a different directory than 'fastboot -i 0x0B05....'
You cd'd into c:\android-adb
You have to run the fastboot cmd out of the same directory your fastboot.exe is in. And twrp.blob has to be in that directory (or folder) too.

Ah, could that have caused it? Figured the connection check could be done from anywhere - maybe that's what triggered the error. Tried again - although now without the check since I know it's connected and recognized - and it worked :laugh:
Thanks!

Do you have nvflash backups? If not you've killed it interrupting a low level nand flash.... I don't know what you were expecting to happen?
If you only have APX I'm sorry to say there are only 2 ways to recover.
1. NVFLash restore
2. New mother board

They'll know you unlocked it as you had to use their unlock tool which dialled home and got the unlock keys....... so yes it is in their database so you warranty is now void I'm afraid.

I had similar issues and spent many a day trying to fix my TF700, almost resigned to the fact that the motherboard was stuffed, but then came across a method that I hadn't tried and now I am back up and running with a stock Rom. Here is the record of what I did, maybe it will help:
Asus TF700T Tablet fix - And the standard disclaimer: I am not responsible if you misunderstand instructions I give here, if my instructions are wrong, if you forget to charge the battery and the tablet dies halfway through a flash or if your house goes up in flames. YOU DO THIS AT YOUR OWN RISK
Ok, so I think that I may have lost power during an upgrade (can’t think of any other reason for it!!) and ended up soft bricking my Asus TF700T tablet and recovery attempts would just lead to the dead Android with a red triangle with an exclamation point in the middle. My warranty having expired with Asus and any attempt for their assistance proved fruitless.
Well I researched and tried absolutely everything out there – (Hard Reset, installing TWRP, used a tool called Motochopper and flashing a custom ROM, downloaded and renaming .zip files, putting it onto a Micro SDcard is formatted Fat32, Scotts Tf700t Recovery etc.etc. etc.)
I even took it to the local shops and paid to have one of the Mobile Technician pop-up stores take a look at it, then a friendly techno geek………all with the same suggestions most likely a motherboard/hard drive problem.
My Asus TF700T tablet eventually ended up with just the plain white ASUS logo in the middle of the screen, some small print in the top left corner followed by the dreaded words “Unrecoverable Bootloader Error (0x00000000)”.
During all of my research I was led to believe that if you can still get to the recovery screen, where you see the 4 icons, all is not lost so I persisted.
Here is the instructions that I followed that restored my TF700T:
Download and install ADB, Fastboot and the required drivers - Download and run this cool little tool which has it all packed into one: [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
NOTE: at the moment Fastboot seems to have issues with Windows 8
This awesome tool installs the ADB and Fastboot.exe to a folder on your C:\ drive (look for a file titled “adb”) as well as the corresponding drivers. This takes about 15 seconds to install following the prompts.
I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:
E:\asus>fastboot erase system
******** Did you mean to fastboot format this partition?

fastboot -i 0x0B05 flash system c:\adb\TF700T\blob - depending where you stored your blob, also this was the first time that I saw the loading bar appear on my tablet.
It will now go through the process of reinstalling your Android stock ROM and you should see the something similar to the following:
E:\asus>fastboot -i 0x0B05 flash system e:\asus\blob
erasing 'system'...
OKAY [ 1.731s]
sending 'system' (800935 KB)...

fastboot -i 0x0B05 reboot
E:\asus>fastboot -i 0x0B05 reboot
rebooting...
finished. total time: 0.020s
E:\asus>
I disconnected and rebooted My Asus TF700T and I now have a fully functioning Tablet with a stock ROM.
It has been reported that after completing this you may have some issues getting back get into recovery, hitting RCK and getting the dreaded dead Android (with a red triangle with an exclamation point in the middle). I have not attempted this but have been led to believe that flashing TWRP 2.7.0.1 via Fastboot works.
All acknowledgement and appreciation for this method should go to Buster99, a Senior Member of XDA Developers

And to Snoop05, also a Senior Member of XDA Developers for the awesome ADB/Fastboot/Driver tool.

To whom I am most grateful for the return of my tablet to a working state, I hope this works for you. Good Luck.

A big big thanks. This instructions worked for my Asus tf700t. It was hard bricked.

I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:

Asus TF700T boot loop

Some time ago I successfully unlocked my TF700 and installed one of the Cromi-X roms. The machine wasn't improved that much and was still very slow with frequent messages asking if I wanted to wait for apps to respond or to close the app. I thought I would try the "Revisited CROMi-X-ET_v3.0-RC2" rom as that allowed the f2fs file system and I wondered if that would be faster. I installed TWRP version twrp-3.0.0-0-tf700t and did the install of the above rom using TWRP and choosing all the default options which reformatted some of the partitions to f2fs.
On reboot I got the start screen and then after a while a reboot again repeatedly. I tried booting to recovery and just got the Teamwin screen.
I then reinstalled TWRP using fastboot and a USB connection. I have tried twrp-2.8.7.0-tf700t, twrp_tf700t_kang_2.8.7.4, and twrp-3.0.0-0-tf700t and all give error messages when I do a wipe, try to restore a previous backup or try to install a new ROM.
On 2.8.7.0 the log I get from a wipe is:-
E:Unable to find partition size for '/misc'
E:Unable to find partition size for '/staging'
Erimary block device '/dev/block/mmcbblk0p8' for mount point '/data' is not present!

The twrp_tf700t_kang_2.8.7.4 version gives similar messages except it says failed to unmount system cache and data. The log from twrp-3.0.0-0-tf700t is the same as the kang version except this one says failed to mount the three partitions.
After reading another thread with similar symptom, I tried to format a partition using adb with the shell command:
make_ext4fs /dev/block/mmcblk0p8
this returns Need size of filesystem.
I would be grateful if anyone could help (or is my tablet irretrevably bricked).

What's the version of your bootloader?
Boot to TWRP and run "adb shell dmesg > dmesg.txt" and post the resulting file.

I did this some time last week but got no text file for some reason. Repeated it without the redirect to file and copied from the cmd window. It's a very long file however. Do I paste it in here or is there some way of attaching it so you can see it (I'm new to posting in forums)
How do I get the boot loader version?
Thanks for trying to help.

You need to fully reboot after installing TWRP via fastboot (however you can go directly to the bootloader menu and select RCK, no need to start Android), otherwise it can't access your partitions.

Not sure I understand about the reboot after TWRP install. When I install TWR the tablet is sitting with the three icons RCK Android and Wipe Data. After install completes if I press Vol up with the RCK flashing TWRP works. If I reboot straight away TWRP hangs on the start screen or tries to reboot after a time depending on which version I installed. Same thing happens after powering down from running TWRP without the reboot.

There's your problem, as _that said: You need to reboot after flashing TWRP before you can use it:
Flash TWRP
Reboot into bootloader
Enter TWRP by selecting the RCK icon.
I know you said TWRP hung if you reboot straight away, but that is strange. Describe step by step how you flash TWRP.

OK.
I boot TF700 with vol down pressed. Connect USB to computer running windows 10. Open cmd window. (copy from cmd window below):
C:\adb>fastboot flash recovery twrp-2.8.7.0-tf700t.img
sending 'recovery' (7372 KB)...
OKAY [ 3.418s]
writing 'recovery'...
OKAY [ 6.528s]
finished. total time: 9.951s
C:\adb>fastboot reboot
rebooting...
finished. total time: 0.020s
C:\adb>
Holding vol down when typing fastboot reboot. Press Vol up when RCK is flashing. Teamwin screen comes on then briefly flashes off and comes on again and that is as far as it gets.
Same thing happens if instead of typing fastboot reboot I press and hold the TF700 power button to reboot.
If I skip the reboot and press Vol up after the flash has finished TWRP starts up and after a delay I get all the various buttons to Install, Backup, Restore etc.. Then I get the storage not mounted problems

Do not touch any button on the tablet after the recovery flash. Just type fastboot reboot, then hit enter.
After you've seen the Asus logo with a blue bar underneath filling up you can reboot into the bootloader and enter recovery.

Just done that. I get a blue bar when I flash.
After fastboot reboot the screen blanks then the Asus Logo comes up but no bluebar. Eventually after displaying the Asus screen for about 35 seconds the tablet reboots itself in the bootloop I originally mentioned. Booting to recovery gives me the teamwin screen hangup I described above.
I repeated and this time instead of waiting on the Asus screen I rebooted from the Asus screen by pressing and holding power and vol down. Same happens TWRP hangs on Teamwin screen
Sorry I'm causing all this trouble.
Regards
Ken

Never seen that before and I don't have an explanation for it either....
What kind of wipes did you do before flashing the new rom?
Don't know.. maybe @_that has a better idea, but at this point I would flash the Asus firmware in fastboot and start from scratch.....
Hang in there for word from @_that, otherwise I can hook you up with instructions for the fastboot firmware flash

I think it's crashing due to a corrupted filesystem. Reboot to TWRP, and with the splash screen flashing, run this:
Code:
adb pull /tmp/recovery.log
Post the resulting file.
To reformat /data as f2fs (be careful with this command and press Enter only after double-checking that you got the "p8" right):
Code:
adb shell mkfs.f2fs /dev/block/mmcblk0p8

_that
I posted the recovery log http://pastebin.com/PdZVbEsC title KenHanleyrecoverylog.
Just did the format of /data then installed TWRP again. Reboot still didn't give a blue bar but Yipee The bootloop is gone and I'm into the setup screens for the ROM I flashed that caused all the bother. Thank You
berndblb
I looked on the Asus site for firmware but they don't list the TF700T anymore. I would be grateful if you can point me to the files and instructions for the Asus firmware in case I do need to do a restore to original.
Thanks again to you all for the help

It's not the rom that did it - I'm running it without trouble for months! It was what you did.
http://www.transformerforums.com/fo...e-firmware-tf101-tf201-tf300-tf700-tf701.html
Check out post 2 and download a copy. Who knows when Asus takes it down entirely....

I didn't mean to imply it was the ROM. It seems to be running OK now. I think somehow the formatting of \data went wrong during the install but I can't identify anything I did that could have caused it. Anyway I'm just grateful to you guys for digging me out of the hole I dug for myself. Thanks for the link, I got to the firmware download page OK from that. I'll grab everything I can now while the going is good.

I realize this is an old post, but hopefully ....
I have the same problem except that it will only boot to the splash screen of TWRP3.1.x.
I had KatKiss 7.1 on it and rebooted it and into a loop. I re-flashed TWRP V3 via fastboot and the much discussed blue line was there, a "fastboot reboot" just sent me into the boot loop again. Pwr/Voldn gave me the 3 flashing icons, but selecting recovery just gives me the TWRP loading screen for about 10 seconds or so, then reboots.
I'm assuming I have to start from scratch as well but am a bit confused as to which firmware from asus' site and how to do this.

Strange - I wonder what it is that prevents TWRP from booting....
Did you try the command from above to reformat data to f2fs?
If nothing resolves this you can always flash the stock blob in fastboot.
The firmware is here: https://www.asus.com/support/Download/28/1/0/11/fq2B3oq64av1O95/8/
Download the SKU for your region (most likely WW or US).
Unzip it twice and copy only the blob into your fastboot folder.
Then try this:
Code:
fastboot erase userdata
Now try to boot into TWRP via the buttons
If that did not do it, continue with:
Code:
fastboot erase misc
fastboot erase cache
Again boot into TWRP and see if that did it.
If not continue with this:
Code:
fastboot erase system
fastboot erase recovery
fastboot erase boot
fastboot flash system blob
fastboot reboot
The commands will finish fairly quickly except for erasing data and flashing the blob. Be patient.
If you're not the inquisitive type who wants to find out what the problem is and more the roundhouse-punch-radical type you can also run all the above commands one after the other in one go to get you back to stock. The order is not important as long as you flash the blob last. Before rebooting that is.
That should return you to a stock JB 4.2 system.
Then flash TWRP, format data, convert it to f2fs and finally flash the rom or restore your last nandroid.
Good luck

[HELP] Factory Reset from Settings while on Custom ROM

As the title says, I (without thinking) did a factory reset from within the settings menu while using a custom rom. My tablet boots and sits on the attached screen. I cannot access fastboot but while on the screen I have ADB access and can send commands. Also, none of the Volume&Power Buttons combinations will work. Please advise..

Is that a serious question???
I used red size 6 type in that post to make clear what that trick is NOTfor.....
You must have done a little more than "accidentally wipe Dalvik" my friend. Dalvik would just get rebuild on the next boot if you wiped it.
The message that no MD5 is found is pretty normal if no MD5 is present, but it would not prevent you from flashing the rom.
My wild guess is that you somehow corrupted /data and it won't mount, but I don't really know because your post lacks anything that might be helpful.
Like specific information.
Try again.
Harder.

I'm still not sure what happened. I was flashing KatKiss-7.1_TF700T_015.zip and left my tablet on my desk. I ran out to the store and came home to my 6yo son holding the tablet and telling me it wasn't working. From what I gathered from what he said was he typed "yes" but wasn't sure what option he picked in TWRP. Going through options I think he picked the option to wipe cache dalvik after the rom was flashed but I am still not 100% sure what happened all I know is I'm stuck on Katkiss boot loop and when I go into TWRP to flash anything else it tells me failed no md5 or something along those lines

To whom I am most grateful for the return of my tablet to a working state, I hope this works for you. Good Luck.
Thanks to Browndog181 for this great instruction he made.
Good luck to bring back live to your tablet.:

I'm still not sure what happened. I was flashing KatKiss-7.1_TF700T_015.zip and left my tablet on my desk. I ran out to the store and came home to my 6yo son holding the tablet and telling me it wasn't working. From what I gathered from what he said was he typed "yes" but wasn't sure what option he picked in TWRP. Going through options I think he picked the option to wipe cache dalvik after the rom was flashed but I am still not 100% sure what happened all I know is I'm stuck on Katkiss boot loop and when I go into TWRP to flash anything else it tells me failed no md5 or something along those lines

So you got a little software engineer in the house, eh? :cyclops:
For these little rascals you need Apple devices: Safely locked down so the average user cannot do much damage :laugh:
You can do the buster99 described in the post above, but I would leave that as a last resort.
Sounds to me as if your son formatted something and since nothing exciting happened after typing "yes", he tried pushing some other buttons, interrupting the format and corrupting the partition.
I assume you can still boot into recovery and use it and fastboot is also accessible to you. Correct me if wrong.
Use TWRP's build in file manager to check if you can see the contents of your sdcard. If you can, it was not /data he formatted, but /cache or Dalvik. If so, just format cache, wipe Dalvik and reflash the rom
If /data is not accessible you'll have to format it from the Wipe > Advanced menu. That process takes 1 hour+, so send your son out of the house on a play date or some such....
That you see "md5 not found" probably means the box for "Verify MD5" (or "Check MD5" or something similar, can't remember what the official TWRP had there) is checked on the Install page just before you flash. TWRP will abort the installation if it does not find a MD5 for the zip you are trying to flash if you told it to look for one...
Make sure that is unchecked, then flash the rom.
If none of this works, take screenshots or write down the error messages you get and post them.

Here are pictures of what happens when I try to reflash

Yes, /data and /cache cannot be mounted. Did you format them in TWRP?
Your version of TWRP is pretty outdated. You should update it to 2.8+ at the least, the last version is 3.0.2.
Did 2.7 even support f2fs? Can't remember....
Remember that if you format data you end up with ext4 file system and have to convert to f2fs again.

I think i'm sending my son to boarding school. I'm not sure if he formatted them he has no idea what he did I know I can only use external sd to try to flash should I get TWRP 3.0.2 to my extenal sd and flash that or will that not work since it may have to be reformated? and how do I go about that?

No man, you have a working recovery now. Fix your problems first, then update the recovery.
BTW, I don't even know if you can properly flash Nougatella with TWRP 2.7. Maybe it's YOU who should be sent to boarding school... :angel:
Ok, so go to Wipe > Format Data, type yes and place the tablet on a high shelf. Leave it alone for an hour plus, this takes a while (and make sure it has enough juice)
Then go to Wipe > Advanced > check Cache and swipe the button. This will take a minute or two
Now go back to the home page, go to Mount and see if it lets you mount data, cache and microSD (check mark next to it). If it does not, reboot into recovery, go to Mount and see if they are mounted now. You are probably ok at this point. If you can mount the partitions you can flash a rom, but I think you should update TWRP first.
I don't believe anyone has made a recovery flashable package for 3.0.2 so flash it in fastboot. If you are not sure how, go to the General section and check out my Beginners Guide - it's all in there.
Once that is done, when you reboot (fastboot reboot), be ready to grab the tablet. Let it buzz once, then push and hold the Volume Down button to get into fastboot again and enter recovery through the RCK icon.
You should now have TWRP 3.0.2 on there.
Now convert data to f2fs (there's another guide in General for that), then flash the rom, gapps and SuperSU.
Enjoy
