When I hold the power button plus Volume down key I am only getting two options. One is to wipe data and the other is to enter USB Fastboot mode. I just upgraded to the latest TWRP recovery and when I click the Wipe icon the TWRP splash screen shows up for a second. What I am hoping is that someone has some insight as to why the recovery icon has disappeared and how to get it back. Usually I am not the person asking the questions generally I am the one answering. If anyone has a clue it would definitively help. I did search and found a couple threads where something similar happened but there was no direct answer as how to fix it. Please help.

I had a similar issue when I restored a TWRP backup I made with pre version 2.2.1. I was able to get help from the Dees_Troy on IRC.
Notes from IRC conversation
Whatever you restored from your pre TWRP 2.2.1 old backup is not a kernel. The dev that made the original device configuration files for the 300 couldn't find boot . So he just threw boot onto the wrong partition you need to install a working kernel via fastboot.
Steps that got me backup and running.
1. Flashed latest TWRP via fastboot. 'fastboot -i 0x0B05 flash recovery twrp.blob' rebooted
2. Downloaded a cm9 rom and opened the zip file and extract boot.blob . Flashed with 'fastboot -i 0x0B05 flash boot boot.blob' then rebooted.
Now TWRP recovery worked and I was able to install a new custom rom.
Backups made with version 2.2.1 or grater work correctly for me now.
Thank you Thank you Thank you!

hey Im sry I never posted here b4 but I think this thread is the closest to the problem I have. My tf300 jad 4.1.1 ota update, i decided to change the rom since it seemed to have so many advantages. I installed TWRP correctly and according to the process I made later with debugfs tool I got root. It was all good but then I messed up, I installed Hydroponyc rom without backing up my rom and from then on, all hell broke loose. I can acces Clockworck (I changed TWRP for clock thought it might help......) and fastboot but any rom I install it doesnt go past the first asus logo that says device is unlocked on the upper left of the screen. Is there anyway u could help me please? Forgive my noobness I never posted here b4 I dont know if Im breaking any rule but i dont wanna wind up with a very expensive paper weight.
Did I brick it?

hey I was super frustrated by this but I took some time out and then I found this post I tried it and it worked perfectly give it a shot
Looks like partition sizes chaged with the Asus update. I couldn't flash CM10 or any other rom as well (signature mismatch). If you installed the official 4.1.1 update, you need to manually install it again. Older versions and rollbacks wont work unless you push to some trickery mmcblk0p4, but that's another thread in itself
Download the JB update from Asus's website (if you still have it, that's fine) and extract the blob file. Put the blob file in teh same directory as your fastboot. Boot your TF300 into bootloader and enter:
fastboot -i 0x0B05 flash system blob
It will take a while to install, so be patient. Hope this helps

UPDATE 1: I can see the shiny-silver ASUS and the progress circles, waiting to see what happen!
UPDATE 2: Setting up Jellybean now (Welcome setup)!
UPDATE 3: Looks like it's working!
Dude, thank you so much! I'll fool around with it. Is there a root method working already? I was wondering if there's a way to restore my backups, at least the ones I made for my gaming progress.

you can flash the file named "blob" extracted from stock JB zip file(download from ASUS website,now there is only US SKU,10.4.2.29),it's about 7XX MB,then use the command "fastboot -i 0x0B05 flash system blob" (put the blob in the same directory with fashboot),It will restore your JB OS.till now,other rom can not work by this way.

What if you can only boot to APX mode? I only have the option of using that because my unlocked bootloader got erased in the process of updating to JB. Is there a way to install a bootloader using fastboot? Or will it only work with an existing bootloader?
In other words, when I issue the fastboot command
fastboot -i 0x0B05 flash system blob
I get "waiting on device" and nothing happens after that.
Thank you, this worked !!!!!!
Hi there, Can anyone help me to unrick my tf300, its stuck on the logo screen.

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.

but fastboot need a unlocked bootloader, no?
Sent from my ASUS Transformer Pad TF300T using xda app-developers app
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.
TF300T blocked on boot screen
hello everybody,
my name is jonathan, and i have a very big problem.
My Asus TF300t is blocked on boot screen after try to install a new rom on JB 4.2.2.
>My clockworkMod reconvery is v6.0.1.0.
I tried to install several roms, offical or not but the problem is the same, "The device is unlocked" on the boot screen Asus...
I read the previously posts and :
- i installed on my pc the sdk
- i dowload the "blob" file and i placed it on tools directory
- but, the actually problem is whis the lign "fastboot -i OxOBO5.... (i have copied and paste it on schell command) and enter
load_file: could not allocate 820157833 bytes
error: cannot load "blob": not enough space
can you help me please ?
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.
See you soon

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.

same problem of space

Hello man,
I try your method but the problem is the same when i want to copy the blob file, "not enough space ..."
fastboot erase system OK
fastboot erase recovery OK
fastboot erase userdata OK
fastboot erase boot OK
fastboot erase misc OK
fastboot erase cache OK
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob PROBLEM
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 ?
Thank you very much

which blob file did you use? Was the zip appropriate for your region? also what was the last stock rom version you ran - you said you wanted to update to 4.2.2 - what was the old version?

Hey guys I have been browsing around here and the web and cant seem to find how to properly (or even if I can) root my Transformer TF300T.
I have went over multiple guides on this site, tried many different .img files and tried to load CWM a number of times.
I have the bootloader unlocked and that went fine, but when I load up fastboot and try to push an recovery.img to my device it fails, I once got it to where it didnt fail but it just sat and said waiting for device and never made it passed that.
So anyone know whats up? Or if I can even root 4.2.1 on this device yet?
Many people who are on 4.2.1 was able to root it via this method here. Take a look.
Its still not working, here's what my CMD says when I run the command
C:\Users\Stryder\Dekstop\TWRP>fastboos -i 0x0b05 flash recovery twrp.blob
sending 'recovery' <7500 kb>...
FAILED <command write failed <unknown error>>
finished. total time: 0.636s
And this is with the recovery files that were downloaded from the link you just provided
Any ideas?
Ok i figured out what the starting issue was, the tf300t model only works properly over a USB 3.0 port even though it still connect to a USB 2.0, so that problem is solve. But now I have a new problem.
I have Twrp v2.2.2.0 installed now and can boot to it just fine, but when I go to install a .zip file noting is showing up in the file manager, and I cant even find the proper folders, i placed the rom zip i had in multipe folders, and went through every folder that was shown in my twrp file manager and there is noting to install in any of the folders??
So ya, lost again
This version worked for me, just ignore the password request.

No USB icon
Hi Guys,
I have 4.2.1 installed and want to move up to 4.2.2 however i now notice that when I try to boot back into recovery I have no USB icon to reinstall TWRP. I used TWRP 2.5 to install 4.2.1. Can someone explain how I can get TWRP back onto the system and get my USB icon back so I can keep up to date.
Your assistance will be gratefully appreciated.
Cheers
Asus TF300T
4.2.1 modifies the recovery accessing screen/halfboot thingy. So Fastboot starts by default once you acces the menu. Same here. Still can't mount **** but fastboot works.
can'troot
I've gotten twrp installed and can boot to recovery, but for some reason flashing a root file won't take hold.
Opening supersu and superuser other fail updating the binaries, and when I try to flash a pre-rooted romantic it hangs on he Asus logo.
Any thoughts?
Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!
I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Put the twrp.img into your ADB folder, where you installed it. Then run the next command.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...
I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

Damn, so I'm screwed. Why does Asus have to such so much...? You can no longer unlock afaik.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

I've tried every firmware and unlock tool combination. Nothing works. I sent them an email a day ago. Depending on there response, maybe I'll try calling. I'm so fed up with this tablet, I'm about to throw it out my window. $400 POS. :good:

Did you ever get your tablet fixed? I am having some problems myself after a miserable m9 update.
First I'll give credit where it is due. From two threads on this site is where I got help with this issue:
I followed THIS guys steps for manually erasing and got the recovery images and lots of other useful information from HERE. Thank you guys very much!
OK, so, hopefully I can help someone with my little story as well. I was having issues with apps and programs crashing on me with lollipop and the new marshmallow update. The tablet just wasn't working properly and moving slow. I even had the SD card holding all my apps and larger files so I didn't overload the internal storage. So, I decided I wanted to flash back to factory/stock recovery and go from there. I did this using THIS method. I flashed via the "flash-all.bat" file (the command in fastboot is the same as the file name). I should note that there was one instance that failed during the install (I did try it again and got the same failure). Said something about “did you mean you wanted to flash this partition” or something, then showed it failed. After flashing I hit continue on the bootloader screen of the tablet and it said it was "cold booting." After about 5 minutes or so it started to boot but never made it past the NVidia screen. I tried wiping the phone with factory reset, wiping the cache, etc. and then re-flashing the recovery (again with the .bat file). I tried flashing TWRP but it didn't install apparently, because it still went to factory recovery. I even re-locked and then unlocked my bootloader to see if that would set everything straight. Nothing seemed to work. I knew I would eventually find a solution though so I kept looking. Stumbled on some other people that had the same issues but no solution (hope those people got it figured out). So here's what I did after some more research:
First, if you're in this situation and you did factory reset to try and resolve the problem, you may feel like you can no longer communicate with the device via fastboot/adb, but as long as you have the usb drive and your SDK tools installed (I used CodeWorks for Android all-in-one program) that shouldn't be a problem. You'll just have to be in the bootloader on the tablet.
-If for some reason you deleted or uninstalled your drivers and tools you'll have to download them again and then, the computer should still be able to communicate with the tablet. In the device manager under portable devices it will still show up as Module something or other. So the computer still sees the device but doesn't fully recognize it yet. Don't worry, this should still work! Just make sure you that fastboot is seeing the device by inputting "fastboot devices" in the command window and a 14 digit serial number should pop up. If it just says "list of devices" or there's nothing then you wont be communicating with the tablet.
Your device should be connected to your computer and started in bootloader mode. On your computer you should have the command prompt for adb/fastboot open. I just go to the folder where the .exe files are located and hold shift and right click in the white space of the folder, then select "open command window here."
From here follow the erase steps: stolen from manigault! :highfive:
fastboot erase system
fastboot erase userdata
fastboot erase boot
fastboot erase recovery
fastboot erase cache
Then flash your recovery MANUALLY:
fastboot flash recovery {dir}/recovery.img
fastboot flash boot {dir}/boot.img
fastboot flash system {dir}/system.img
fastboot flash userdata {dir}/userdata.img
fastboot flash staging {dir}/blob
fastboot flash dtb {dir}/tegra124-tn8-p1761-1270-a04-e-battery.dtb
You can download whatever recovery version you wish. I downloaded 2.2.2 because that's what my device came with out of the box on Christmas 2014. It will more then likely be a .zip file. To make this whole process a little easier simply extract the files in the .zip file where the adb.exe and fastboot.exe files are located (folder should be named platform-tools) and you can completely eliminate typing the whole directory before the file name. ***After your done flashing everything you can go back and delete those files if you want. Just double check that you're deleting the right files by looking at the original zip file. Not sure if it makes a difference but I deleted them anyway.
For example the commands in fastboot will look like this exactly :
(after extracting recovery files into platform-tools folder)
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
Note: Do NOT use the flash-all.bat command as this doesn't seem to work for this situation. Do it manually like shown above. And let each individual process complete before attempting to input another command.
After this step I didn't select continue on the bootloader. You can either select reboot or simply input "fastboot reboot" into the command window. It may take about 5 minutes to start installing everything but just be patient, it should start. Sometimes with these things you have to do things twice before it works. If for some reason it doesn't work the first time then start from the beginning and try it again. It took two times for me, but that's because I installed system.img twice and was getting double screen. Newb error... and I was a bit inebriated last night when I did this.
Hope this helps someone!
Thanks again to manigault and MidgetMob!
NVIDIA download files HERE!
i think i done the same thing
but the problem i now have is i cnt get tablet into fastboot on pc. i can load fastboot on tablet with power and volume down , but the tablet only shows as MTP device in device manager. i have downloaded drivers from nvidia and no matter what i try i cant install them i have been through all instructions but scince it went to mtp device i cant get device showing in adb. The only way i can get device showing in adb on pc ist to select apply update from adb ! but none of these commands listed in your post will work because its in sideload. is there anyway i cn reset , flash custom rom ect bu using commands while device is in adb sideload.
all i get is now send the package you want to apply to the device with "adb sideload <filename>".....
if you could shed any light on this it would be much appreciated , thanks , lester
did you update official android 6.0 before? then, not working stock recovery, stock boot...
If you can enter bootloader mode, download unofficial twrp 3.0.0.0 (here http://forum.xda-developers.com/shield-tablet/development/wip-twrp-2-8-0-1-unofficial-t2877117) and flash it.
i have a working boot.img file on marshmallow if you want.. please reply.
Sorry for the late response! I have no clue how you got into sideload??? Are you talking about through the recovery on your device? You're not able to get adb/ fastboot to recognize the device, right? It doesn't matter how you get the tablet into the bootloader. Whenever you have the phone in the bootloader then you'll use the fastboot command to "talk to" the device; i.e. "fastboot devices" without the quotes. That command should show your device if it shows as an MTP device whenever you open your "device manager" in windows. That's the same exact situation I was in. Download the codeworks from nvidia like I linked above. Hopefully then you should be able to recognize your device through the bootloader. If not DM me and I'll try to help you.
I'm having the exact problem as Lester. Tablet boots into bootloader but won't connect to computer. So I go into recovery mode and nothing works except apply update from adb. Which brings up the side load message that Lester quoted. And bootloader is showing "device=locked". I am attempting to fix this tablet for a friend that messed it up trying to flash a custom rom. Problem is he had no idea what he was doing and I'm not exactly sure what he did. I do however have a lot of experience with rooted android devices and flashing so any help would be GREATLY APPRECIATED!

Also, I've already tried flashing stock rom back onto the tablet by applying update from sd card function in the recovery but when I try to do that the tablet for some reason can't mount the sd card.

If you've got the device in bootloader then you need to use fastboot, not adb. Try the command 'fastboot devices' and see if the device id is listed. If so then grab a factory image, unzip it and use fastboot to flash the .img files using the commands 'fastboot flash system system.img'. Just make sure to match the partition names to the files.
Hello i have similar issue except when i try flash something i get this error ''remote: file write failed''
and i have to reboot into fastboot to get it flashing fully
but even though i managed to flash everything by rebooting when i boot system nothing shows up, i can just see the back light coming on and turning off after a while
Please help
