[Q] Computer will not see tf300t in fastboot - Transformer TF300T Q&A, Help & Troubleshooting

hey i've tried searching the forum and couldn't find anything the helped.
i'm trying to load a custom ROM on my transformer but i can not get my computer to recognize my tablet in fastboot
i have already unlocked the device. i can get the bootloader menu on the tablet but when it's connected to my computer and i go into cmd i will type fastboot devices and it doesn't see anything it just goes straight to the next prompt.
i'd tried reloading the drivers and this has not worked either.
any ideas?

Try using a different USB port or cable. What does the device show up as in device manager on your computer?

i'll try a different port but the computer does recognize the tablet plugged in when it's fully booted. had it listed as Asus Transformer TF300T.
don't have another cable i can use.

Are you using the full Android SDK for fastboot or one of the minimal versions? You may want to try a minimal version to get a fresh install of fastboot. http://forum.xda-developers.com/showthread.php?t=2317790

Computers blind to NS4G. Help?

Hey folks.
I have been trying to get my wife's NS4G back to stock to get the JB OTA. I have downloaded all drivers multiple times on multiple computers (windows). I have tried 3 or 4 different USB cables. I have downloaded pdanet. I have downloaded the JAVA SDK and updated everything about it.
My computers cannot connect to the NS4G.
USB debugging is on. When I try to turn on tether, it tells me USB is not plugged in.
I have been able to restore the stock ROM (2.3.7) via CWM, but now I no longer have a recovery. It is still rooted and unlocked. Rom Manager is installed and it will not download CWM Recovery.
I need some way to get a recovery onto it. CMW or stock.
Does ANYONE have any suggestions?
Thanks in advance for all suggestions and particularly to the one that will work.

If you are running Windows 7 hold down the shift key and right click then select open command prompt here. type ADB devices and if your drivers are installed then you will see your serial number. Remember to be in fastboot when you install drivers. then use ADB to reboot bootloader. when in fastboot type "fastboot devices" and you should again see your serial number to know that your drivers are all installed correctly. You need to fastboot flash a new recovery image. Hope that helps

Drivers are installed, as I can see my S3 fine as well as adb getting my serial number. The computer, nor adb, can see my NS4G. I have tried a desktop as well as 2 laptops.
Will be trying Vaelek's idea of wireless adb this evening.
Thanks for the suggestion.

Drivers are NOT installed properly then. Drivers are installed on a per device basis. If your phone doesn't get recognized, then they are not installed.
Chances are your device ID isn't found in the .inf file of the drivers. I know back when I rooted my phone over a year ago I had to manually change the inf file and add my device.
If you start your phone in fastboot mode and plug it in, when you go in device manager you should see an unrecognized device with a yellow question mark. Right click it, then Properties, then Details tab. Give me the information in the Device Instance Path.
Will check this out and post info when I get home tonight. Thanks for the input.

Started phone in fastboot mode. Plugged it in and watched Device Manager. Closed device manager and re-opened it for a good refresh. I get nothing new. No unrecognized device and no Android Device like when I plug in my S3. ADB Wireless wont connect.
OK... I just cleared my sd card and was able to install CWM. One hurdle cleared...
I still need to get stock ROM and recovery. Is there anyway to do this WITHOUT being able to connect via adb?
Thanks again for any input.

[q] twrp 2.5.0.0

Hello,
I followed Hasoon's all-in-one root toolkit and flashed the included TWRP 2.5.0.0 onto my AT&T HTC One X. Now I cannot do anything, whatever I do, it tells me "Unable to mount /cache". Could you please help me? I can't mount the sdcard to the computer either, so I am sort of stuck.
Thanks!

I was able to wipe it. However, it still gave all these same unable to mount /cache error messages. The data is gone though.
When I connect the mounted device to the computer it still doesn't recognize it.

Does the PC not recognize that anything is connected or does it detect that its plugged in but can't find the driver?
What rom is currently installed on the phone?

Currently I think it recognizes the phone as a media device (or similar, I forgot the name), not as a disk drive. I am on a Mac, and I have Android File Transfer installed, which then tells me that the device cannot be opened. On Windows it couldn't be opened either although it talked about a driver issue. I currently only have a Mac, but from Monday I could work on a Windows machine again.
The ROM currently being installed is the original AT&T provided ROM.
Thanks so much!

What version? IS it already installed on your phone? I'm trying to find out if you require MTP drivers or not. Latest version of sense/stock Roms require MTP driver to access the SD card.
In any case I wouldn't suggest using any version of TWRP above 2.3.3.1
So, I would download twrp 2.3.3.1 and check the md5
then fastboot flash recovery recoveryfilename.img
fastboot erase cache
fastboot reboot-bootloader
select recovery from bootloader then try to mount sdcard with twrp.

I see, this all sounds like I need to wait for a windows machine.
I am not sure what ROM version, unfortunately. I bought the phone in December from AT&T, and it all looks like it asks for MTP drivers. I will try this with a Windows machine and then get back to this post - thank you so very much for your help.

Alright, I have tried this with the latest HTC Sync manager: the MTP Drivers however won't install. I have tried with the One X+ of my Dad (which is also brand new, so probably requires the newest version also), and it installs fine and appears as a media device in the explorer. Mine however does not do anything, and driver installation says it fails to install the driver. I have tried manually installing the drivers, however, it seems to have to do with the phone because when I disconnect it suddenly Windows 7 is able to install those drivers, and as mentioned before it also works with a functional phone.
Next week I will be back at work and I have a Windows 8 machine there. I don't have high hopes that it works there, but since there seems to be an MTP driver issue with Win7, maybe there's a chance.
Is there anything else I could do?
Thanks!
PS: don't use your vacation time to root your phone...haha.

OK, so on Windows 8 I am able to install the driver, and it does not fail like in Win7, but I still can't access the mounted storage. The message of the device is:
This device cannot start. (Code 10)
The process hosting the driver for this device has terminated.​

Are you rebooting to bootloader to do the fastboot commands? In bootloader it should say Fastboot in red. Then after a couple seconds that should change to Fastboot USB. I don't think fastboot needs the specific drivers to be on the PC like mounting the SD card requires.

You are definitely doing something wrong. fastboot commands only work within bootloader/fastboot and adb commands only work while the rom is loaded up or in sideload mode in TWRP. It's assumed you know this prior to rooting.

Turn off the phone. Then hold volume down and briefly press the power button. Don't let go of volume down until it gets to the boot loader screen. Wait for fast bot USB to display. Then you can try exad's fast boot commands.

It should change to FASTBOOT USB if you are plugged into a computer. If you connected to the computer after you got to bootloader mode, you might have to press volume up or down to get it to switch to FASTBOOT USB Maybe this is the root of your problem. Have you tried multiple USB cables? Is there any crud in the micro-USB port on your phone? It's a little odd that the micro-USB port would break in a manner that charging would still work but not data connections, but I'm starting to wonder if that isn't the case.

USB not recognized + no Recovery

Hi All,
It has been a time that I unlocked my TF700t then followed the CM10 documentation to install 10.0 using CWM.
Recently I wanted to upgrade to 10.1 but it didn't work and ended with my tablet rebooting undefinitely.
I reverted then to install back the ASUS stock Rom from their website :
- I downloaded the file
- unzipped it (since it contains another zip)
- put it on a micro SD
- Booted into CWM
- installed the zip
I ended with a working tablet on the stock rom JB 4.1 but know I wanted to try again CM but I cannot access recovery anymore. I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign.
I thought I would need to flash another recovery (TWRP or other) using fastboot but now when I plug the tablet to my PC it keeps telling me that the device is not recognized. I tried to install the USB driver but it doesn't get detected.
Can anyone please help ? The tablet is working but I am afraid that it has lost some of its capabilities.
Thanks

Go to your system setting and select storage. Click the 3 dots in the upper right corner and tick the box which is Media device (MTP).. Good luck..

What Windows version are you running?
You may have to uninstall the drivers for your MTP device before installing new ones as well as disabling Windows to automatically install drivers for a new device, then manually point it to the Universal Naked Drivers folder.
Or downlaod Android SDK tool ad through it the Platform Tools and USB drivers.
BTW: When you flashed the stock firmware you lost your custom recovery. That's why you see the dead Droid - it's the stock recovery.
If you can't get fastboot to work you can use Motochopper to root your JB 4.1 stock firmware and then GooManager to install the latest TWRP recovery.

I have tested it on WinXP, Win7, Ubuntu and another box with Win XP. Always same thing the device is not recognized.
When I try to update the driver and point it manually to the naked drivers it cannot detect them.
I guess that even for running Motochopper I will need to get USB working to be able to root my device.
Any help please ? I am stuck with a sluggish stock mod that buries the perfs of my device.

Then it's a driver problem and it's solvable. What do you see in Device Manager under Portable Devices with your tablet connected? Did you uninstall the driver and re-install it?
Did you try to install Asus Sync (which should give you compatible drivers for the TF700)?
So many driver problems lately... there's got to be a pattern to it, but what it may be beats me :what:

Sounds like a windows driver issue to me. You need to force windows to use the right usb drivers. You normally do this by upgrading thenm in device manager. You may have a borked windows installation to fix as well..
Try the ones I have attached.

Im having the same problem and after one day of research I could not find a solution. I bought a use TF700 with a standard andriod on it, no mod, not unlocked, no root. When I connect it to the pc I get the same error, meaning just a USB Device showing up. Tried different PC's with different types of OS, no success.
Did you manage to fix the problem ? I would really appreciate some help because now I can't use that tablet in debug mode to test my android applications and that's all I bought it for. By the way, is there a adb tool that works wireless and doesn't neet root access or can I get root access without connecting my pad to my pc ?
Thanks for the help !
Well did you install adb fastboot drivers on the PCs you tried? Did you try it under Linux? Do you have the original Asus cable you connect it with?
adb over network is an option under Developer Options in Omni and Omni based roms - at least the LP roms. I don't think you can get that with an app you install. Probably needs to be baked into the kernel.

First of all thanks a lot for your response, didn't think anyone would still react on that post because it's quite old. Yes I did install adb fastboot drivers, the device only shows up in the usb section saying usb device not recognized. I tried nearly every driver I found, installed the Andriod SDK, the Asus Sync Tool, the naked drivers... then removed them all (including the hidden ones) and installed just the adb fastboot -> no success. I have not tried it on linux, but on windows 7, 8 and 10. Android version is 4.2.1 and Build is 10.6.1.14.10. I now unlocked it using the apk provided by asus (version 7 , 8 did not work). Still for rooting I need pc connection, so I ordered a new cable today (cable is original Asus though).
I installed the Rom Manager and that tells me the ClockworkMod Recovery and TWRP are already installed. I also tried that recovery (power + vol) and got the same result as nacef meaning " I can access the bootloader but when I select RCK I get the droid laying on his back with the warning sign." Thing is, I don't know what the previews owner did, so it might be the reason he sold the Tablet. Can I get anywhere form that Bootloader ? Maybe boot as a Superuser and then use wireless adb to root the device ?
Thanks a lot for your help, Im feeling that I have wasted the money and the only way to get rid of that feeling is to fix the problem
Grab the Puppy Linux live CD from here: http://www.transformerforums.com/fo...t/46090-guide-adb-fastboot-linux-live-cd.html
It has adb fastboot already installed. If you don't get a connection with that one the problem would be tablet side, not Windows related.
I booted using that Puppy Linux and followed the Guide but no success. After entering "adb devices" I get the output "list of adb devices attached" and than a blank space. So I tried booting in fastboot like you described in your guide and entered "fastboot devices" but that also gives me nothing. Fastboot works though (as it's already included in that image) so I tried a bunch of other fastboot commands but that just results in "waiting for the device".
I don't know what to do now, it has something to do with the tablet itself. Im waiting for the new cable but don't think thats gonna change anything.
You are not trying to do this through the dock port, right? You are connecting the tablet directly to the PC?
The only answer I have left is either a broken cable or one of the pins in the port is bent or broken. Get a magnifying glass and check them out.

Howdy, folks. I recently bricked my tablet thanks to a bad install of CWM, but following Buster's guide I was able to successfully reflash stock firmware and the device runs fine when booted up now.
However, now ADB is not detecting my device. At all. I have tried running the kill-server and start-server commands to see if that would do the trick to no avail. I'm not even receiving an error saying "device not found." Rather, the device listing is left blank whenever I enter the devices command into the command prompt. I can still send commands via fastboot, but I'm concerned that there's something here that I'm missing, or that I have somehow managed to completely bork the motherboard. I have already tried uninstalling and reinstalling the Asus usb drivers, in addition to the ADB drivers/software to no avail.
Does anyone have any suggestions to getting ADB to work for my tablet again? I have scoured the web, particularly these forums, for days looking for an answer, but haven't turned anything up yet. Any help would be greatly appreciated.
Does usb debugging is on?

Yes, USB debugging is enabled; yes that was the first thing I checked.
Any other ideas?
If You use asus drivers it worth to try universal naked driver.

I just installed the naked drivers and tried again, but that didn't work either. Fastboot still works just fine, but I'm still at a complete loss as to how to get adb working again.
Thanks for your help thus far.
Hmm... How windows show tablet when You connect it to PC?

Yeah everything *looks* normal, and appears to be acting normally whenever I have the tablet plugged in. When my tablet is booted up and connected to my pc, I can transfer files to and from with no issue. Also when it's plugged in, there are two different entries under the device manager (one for adb and the other for the tablet itself). It's only when I have my tablet running in bootloader mode that things don't seem to want to work correctly.
I even ran netstat last night to see if there were any programs/services using the same port as adb, and even that turned up nothing. Is it possible that I somehow inadvertently altered the settings on my tablet's motherboard when I installed a bad version of CWM, per my original post?
It shouldn't be posible to brick anything on motherboard with just flash wrong recovery. It might be just "too smart" windows, that reject to use adb driver on same device that alredy used by mtp one. It wasn't a problem before?

It wasn't a problem until I flashed the wrong version of CWM, got stuck in a boot-loop and fixed the problem using fastboot to completely wipe my tablet and start over from scratch.
Edit: I suppose I could try a fresh install of Windows.
Try first remove all drivers and software for tablet. Then install universal naked driver.

Update: finally got adb to detect my device. Ended up removing everything Android-related from my desktop and re-downloaded/installed everything, including usb drivers. That did the trick.
Thanks again for the help.

Did you try to plug a USB stick into the dock's USB port? You should be able to flash from there.
Not sure about TWRP as I am currently trying Phil'z recovery (though will go back probably).
If you want to try Phil'z you can flash that via fastboot from the bootloader screen (hold vol-down).
Hope this helps! Good luck!

Awww, a pity, the dock might have helped. Oh,well.
When you are in recovery, the tablet is not recognized by your PC? You should be able to use ADB in recovery.
Have you ever used ADB before? On Windows you might need to install the "USB naked drivers", just search for that (sorry, I am a Linux user).
If "adb devices" shows your serial number and "recovery", you can run "adb push ROM.zip /sdcard", of course replacing ROM.zip with the path to your favourite ROM. Then TWRP should find that file on the internal sdcard.

You should find an adb.exe somewhere, not sure where you can get a Windows version.
Better read up a little on how to use ADB under Windows, sorry again.
Once you have the adb.exe binary, you should be able to run the commands I gave in my last post.

As I understand it, you should install the naked drivers on your PC before plugging in your tablet. Installing the drivers on your PC does not require the device, but your PC should recognize the tablet once you have them installed. Maybe better to reboot the PC after installing the naked drivers, just to be on the safe side.
If the tablet is still not recognized, try another USB port or possibly another PC. If that won't work I am out of ideas, sorry. Never used ADB under Windows and under Linux it just works. Ahh, I remember people suggesting to run Linux in a VirtualBox and use ADB from there, might be a last resort. Maybe a Windows user looks into this thread and can help.

Weird, but sorry again, never tried myself under Windows.
Well, if you can't use ADB, can you use fastboot when you go into the bootloader menu (vol-down)?
In that case you could flash the original Asus ROM via fastboot: download, unzip twice to find the blob and use fastboot to flash that. Once you booted into that you can install recovery again and then flash your favourite ROM.
Otherwise... no adb, no fastboot, external sdcard in the slot won't work and no dock... hmm, can't think of any other options right now, sorry!

I think there are also USB adapters you can plug into the tablet without a dock, might be cheaper.
And don't despair. Another Windows user should be able to help you getting either adb or fastboot to work. Or do a little more research, there have been tips and discussions on that all over the forum. As a Linux user I just didn't pay too much attention.

Well, if the plug in the tablet is damaged, probably not, as they use the same plug. Might be your cable? A new USB/charging cable might help in that case. I also had a bad USB port in a PC once.
There are so many things involved, hardware and software. Hard to tell, where the bad link is.
