Stuck in fastboot - device not recognized - Transformer TF300T Q&A, Help & Troubleshooting

I can't seem to get the fastboot usb drivers to install....i tried:
a) downloaded the asus android usb drivers but can't install manually because they won't do it on x64?!
b) installed asus pc sync (should install drivers also right?)
now i'm in fastboot usb download and when i connect the cable, it says USB device not recognized.
what can be done?

installed the SDK and now i see the device recognized in ADB, but i can't get it to be recognized in fastboot mode ???!!!!!! same error about unrecognized device...
// EDIT: WELL ****ING HELL, it was the USB port!!! I tried 3 of them (front panel) and same result
Switched to a backpanel port and it flashed TWRP straight away....
**** this, pls close thread.

Usb drivers for your android phone

USB Drivers are let your PC communicate with your device.
If you are executing some ADB Commands, you will need USB Drivers installed which will let the ADB server on your PC communicate with the ADB client on your device. If there are no USB Drivers installed on your PC, you will not be able to perform activities on your device via the PC.
First of All I would recommend you to install Universal ADB Driver Installer.The Universal ADB Driver installer detects your phone and installs the ADB drivers for it.This tool developed by drsmart is your solution to the “device not found” error you might get on executing ADB commands.

Thanks for the info. I tried the univ adb driver installer but it showed I already had the right driver installed. Windows explorer can see my phone but other apps like HTC Sync or myphoneexplorer can't. This only happened after I rooted & installed a new rom. Maybe the rom is faulty...

No access to USB debug
I give up and need some professional help...Ya both kinds.
Here we go, I have the Galaxy 3 d2att I747
Rooted
I was running CM 10.2 with latest nightly, I think 20131208 and decided to update to CM11 via my Cyanogenmod updater but before I did I had read somewhere I should change from CWM recovery to TWRP so I downloaded Goomanager and updated to the TWRP version for my phone then went for the KitKat update and thats when the trouble began.
I am now stuck in a boot loop even if I try to boot into TWRP all I get is the TWRP boot logo then straight into boot loop again. I am almost positive I did a factory wipe as well as cache/dalvik.
Not being able to use TWRP to get into recovery I thought I would just use Odin but I can't get any of my laptops to recognize the phones USB, I just get the windows usb driver error and have tried to install the drivers manually via device manager using my samsung 7 chronos with windows 8.1 and my acer with windows 7. I updated drivers using Samsung Kies and from the website, no luck.
I also ventured into an area that I have no expertise in but I guess thats how we learn so I downloaded the Android SDK thinking I could use it to download and install the google USB drivers that way, but I can't get out of boot loop to make sure USB debugging is checked. The only thing I can access is the stock download mode which would be great if I could use the USB connection.
What am I missing? Any suggestions?
USB Not Recognized Error
I noticed that my phone suddenly stopped being recognized on both my Windows 7 and Win8 laptops. I have been trying to fix it with the drivers but to no avail. However, I plugged my phone in with a different USB cord and voila it was recognized and working. Maybe this could possibly be a simple fix.
My computer stopped recognizing my Skyrocket
Hi Everyone,
I also am having trouble with my win 7 computer recognizing my Skyrocket suddenly. I have been using several KitKat roms and they have been working just fine, except for some reported bugs that the CM devs are working on. I even was able to connect to the computer and explore both my internal and external drives. Then suddenly that stopped and the computer gave me a need to get drivers warning. I've tried to download drivers from Samsung and the computer says they are already installed. I also tried the universal driver download and got the same message. Any help would be appreciated. Like the others on this forum, I wouldn't be able to odin if I got in trouble.
Thanks for your concideration,
drewfs7270
I switched to a different rom and now it's working again !

soft brick
I face bad experienced, the tablet can not boot ( after install TWRP ) but enable to enter the fastboot mode and can be detected by the computer as android adb interface but adb can't communicated with the tablet. (list of devices atached)
I do have a backup file ( I make it before soft brick, I make backup using dd command, because I don't have cwm/twrp recovery ).... but how to flash it ? Tablet chipset is wonder media 8980 OS android 4.2.2
I can not flash it by adb/fastboot.
Maybe someone here can give me a little guide for how to....
I really appreciate for your kindness
Hey, I made an expirience, which might help other users as well.
I have a Sony device (Z1C) and use Windows 10, maybe this will help for other brands and for other Windows 10 users.
I installed drivers for my device and was able to use adb. When I put the phone into fastboot mode, it was not recognized anymore. I found out, Sony has a seperate (updated, maybe?) driver for fastboot mode. When I tried to install this, the driver was not signed and Windows refused to install it. However, you can enter the UEFI (successor of BIOS) and enable installation of unsigned drivers (at own risk). Then I was able to install the fastboot driver and controll my phone in fastboot mode as well as in adb mode.
In conclusion: You might think you installed drivers, because you did, but maybe you did not.
Even on LineageOS page, many people fail to mention that, you DON'T and SHOULDN'T install any generic or universal ADB driver if you have Samsung device. As you can just install Samsung USB Drivers officially from Samsung site. Samsung USB Drivers already contain ABD interface driver just fine so Universal ADB driver is redundant for Samsung phones.

Help needed! ADB issues(detected on phone but not in fastboot)

Dear all,
Please Help me. My One plus one is on CM12 official rom (rooted). Problem is when I connect my phone to computer and use ADB it is detected (adb devices: number & devices detected) but when in fastboot (fastboot devices : nothing is detected) I check in my device manager (yellow triangle on android ) My problem is why CAN it be detected when my phone is on but NOT during fastboot.
Necessary checks done : USB debugging, Universal driver, SDK installed, USB driver reinstalled again, tried changing usb ports on computer, tried on 2 laptops)
I am helpless, tried checking on forums can not find the answer.

Tried adb reboot bootloader then phone boots into fastboot mode but from here..
is total no connection. Tried checking fastboot devices (nothing), fastboot reboot (waiting)
then i tried as u said unplug & plug in (not recognize) from here adb cannot be written anymore. (no more commands can be typed). Tried others like down loading Pdanet ,force install driver..Nothing works. Thinking ,did I corupt the bootloader while I was rooting it last time.?
I think if something was wrong with bootloader you could not either boot .
Do you use antivirus to pc?
Try without antivirus
What happening the false is from computer
Mine is reverse issue. When in fastboot mode, pc recognizes OPO, but when OPO is normally connected to pc, adb is not working. Its charging and can transfer data through USB, but OPO is not recognized through adb commands. Device Manager too recognizes my OPO only when it is in fastboot mode and not when normally connected via USB for data transfer.
I have a software, through which I can REVERSE TETHER my PC's internet to my mobile via USB. Because my OPO is not recognized via USB in normal mode, I can't do that. Any idea, what's wrong with my OPO.
(I have installed Android SDK and google usb drivers, for my OPO to work in fastboot. I have rooted. My pc runs on win7)

Bricked Phone USB not recognized by PC

Need help. I was using Miracle Box to flash stock ROM, I don't know how but the phone (Micromax E453) is bricked now. I tried to start phone in Meta Mode (swiched off phone connected to PC by holding volume up button), it worked once, then following some tutorials I uninstalled (and checked, Delete the driver software for this device) MTK USB COM driver under port. Since then phone is not turning on and PC is not recognizing the device. Tired changing the USB cable and even tried it on another laptop, but no go. Kindly share what else I can try. PC has Windows 10 64 bit and MTK preloader vcom driver always has yellow exclamation mark (always installs with error code 10). I have disabled driver signature verificiation.

Did you have USB debugging enabled in the device's system settings before it got bricked? If not, you might not get it to connect via USB and be recognized.

Thank you for your response. Yes, USB debugging was enabled before it got bricked. I was able to successfully see my device when I ran adb -devices command. I was also able to run fastboot commands. Now its completely dead.

Oneplus 8T fastboot not recognized KB05AA

adb devices command works perfectly but when I'm in bootloader, computer does not recognize my phone. fastboot devices returns nothing. device manager show Android with a triangle under "Other Devices".
1. Tried updating the driver and manually choosing it as Android ADB Interface or Android Bootloader Interface with no luck.
2. Tried uninstalling/reinstalling the USB drivers and adb still works normal but fastboot still won't recognize my phone.
3. Tried revoking USB debugging and reallowing debug from my phone. Still same issue.
4. Tried using original Oneplus USB C-C cable, Pixel USB C-C cable, USB A-C cable, generic USB C-C cable (Oneplus was still not recognized on fastboot but Pixel was recognized so it is not the cable/PC)
4. Tried reformatting my PC. Doing a clean install on everything and still same issue.
My last resort is this thread. I would really like to unlock my Oneplus 8T bootloader and root but for some reason, fastboot does not recognize my phone. I just hooked up my Pixel phone after reformatting my PC and adb/fastboot worked normally like it should.

You can also try installing the oneplus drivers in the oneplus drive that pops up when you plug in your phone
Edit: Scratch that. I guess the 8T doesn't come with a driver partition. Try this https://oneplususbdrivers.com/oneplus-8t-usb-driver-download/
Install Universal ADB Drivers first and then boot Oneplus 8T to fastboot mode, repair oneplus device driver to "ClockworkMod Android ADB Interface" on Windows, you can use fastboot command for unlock bootloader now.
Universal ADB Drivers https://adb.clockworkmod.com/
I had the worst bloody time getting fastboot drivers installed for my 8T (KB2007, T-Mo).
I ended up having to find the device id for my device and manually patch and resign Google's USB drivers to get it working. If you can handle reading batch files and stuff, clone the repositories at https://github.com/fawazahmed0/Latest-adb-fastboot-installer-for-windows and https://github.com/fawazahmed0/windows-unsigned-driver-installer.

Device not recognized in fastboot on Mac and not recognized at all on PC

I'm hoping someone can help me out here. I've rooted phones before and didn't have any trouble previously. I just bought a used Pixel 3 on eBay with the plan to root using Magisk. The only problem is I can't get the device to be recognized at all on my PC. I've tried all the usual things like different USB ports, different cables, cleaning out the port, etc. I have the latest drivers installed and I have a Pixel XL that is recognized by my PC immediately so I know I have the correct drivers installed. Pixel 3 does not show up in Device Manager at all. I have USB debugging enabled on the device, but it never prompts me to Allow USB debugging when I connect the Pixel 3 to my PC.
Now, here's the weird part. I know the cable is working fine because I use the same cable and plug it into my Mac. The Pixel 3 is recognized immediately and I'm prompted to enable USB debugging. ADB then works just fine on my Mac. 'adb devices' shows my phone. But I then try to use 'adb reboot bootloader' and my phone reboots to the bootloader as it should. At this point my phone says it's in FastBoot Mode, but the device isn't recognized using 'sudo fastboot devices' and if I try 'sudo fastboot flashing unlock' it just sits there saying 'waiting for any device'. I've also tried putting it into FastBoot mode manually by using the Power and Volume Down key, but run into the same issue with it not being recognized while in FastBoot mode.
Could the previous owner have done something to the bootloader to cause the device to not be recognized in FastBoot mode? And is there any way to fix it? Why would the phone be recognized on my Mac without issue, but using the same cable and multiple different ports on my PC, it never gets recognized?
Any help would be very much appreciated here as I'm at a loss as to what I can do and fear I just spent money on an expensive paperweight.
I tested the cable I'm using with my Pixel XL and it's immediately recognized by my PC and the notification for USB debugging shows on the phone, so I know the cable is working out. No device ever shows in the device manager when I have my Pixel 3 connected though. I've even uninstalled the drivers while my Pixel XL is connected to hopefully put Windows into a driverless state hoping my Pixel 3 would then show up as an unrecognized device, but no device. I can't get it to show up at all in Windows for some reason and it's not recognized while in fastboot mode on my Mac. Fastboot mode information all seems to match what a Pixel 3 should look like as well, so I don't think the previous owner installed the wrong software causing device id mismatch. Anyone have any other suggestions for what I can try?
