Fastboot not working - Transformer TF300T Q&A, Help & Troubleshooting

Need some help here. Long story short, tablet fell and broke digitizer. 6+ months later finally replaced it but new one wouldnt work. Updated touch screen driver and it works. ADB works but fastboot does not. Used factory ROM to reset device to see if it helps. It doesn't. In device manager it shows ASUS android bootloader interface with no !. Downloaded ASUS pc suite for the drivers still no go. Bootloader reads:
key drivers not found... booting OS
android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.27.5-20130902" A03
Starting fastboot USB download protocol
When i try fastboot devices, it returns nothing. if i try any fastboot commands it hangs on waiting for device. Any help? Thanks.

i have the same problem, waiting for any suggestion/help. If you figure out the problem please let me know

Well still no luck so far. I ahave even tried downgrading to 10.4.2.20 and no dice.

hmm maybe try to reinstall USB drivers on your computer, try different USB cable / port on computer

I believe it has something to do with the drivers. I have noticed ADB only works when i have ASUS PC Sync program running in the background on the PC. If I uninstall it or close the app ADB stops working. I have tried using the naked universal drivers and the stand alone ASUS drivers that are on here and neither of them seem to work for me either in fastboot or ADB. If only i could remember how i use to do it, but i have been away from ASUS products for over a year now..

All right, so i figured out what was going on with my fastboot and it was such a simple thing. After nothing else was working that i could find online i did find one command line that made me think of something and it worked. I looked at my ADB version vis the adb version command. I was on version 1.09. I thought it was a bit out of date but should work since it worked with my tf300 before the screen broke and it sat on a self and with my tf700 before it was stolen, heck it still worked now with my HTC One M8. But i deleted my adb and fastboot folder, installed android SDK and the newest platform tools and tried it. It works!!! So in the end i just needed to update my ADB and fastboot files. I hope this helps some other people with this issue since i saw a lot of post about it and a few solutions but here is a new possible solution.

[Q] Waiting for device..

I've been trying to s-off my phone but its giving me the waiting for device status, after hours of googling i am stumped. I installed the latest SDk/drivers etc. adb devices detects my phone, i've even gone and installed pdanet just to see if it will connect and yes it does. HTC sync detects my phone, but revolutionary doesn't which i find very very odd and stressful. I am running windows 7 64 bit and yes i ran the program as admin. If there is anyone with any insight I will gladly appreciate it.
T.I.A!
MODS PLEASE LOCK THIS THREAD UP SOLUTION FOUND!!
I managed to figure it out by replacing AdbWinApi.dll with the newest one from the sdk. Now I am stuck on fastboot as adb doesn't detect it out now. reinstalled fastboot drivers, but nothing happens.

Fastboot issues

Hey guys I have unlocked my TF300T using the Asus tool.
I am able to into Fastboot mode on the device however in fastboot.exe the command fastboot devices returns no results.
I went back and tried everything with my Galaxy Nexus and that appears fine.
I have a feeling it is the drivers. The install fails when I plug it in giving a yellow question mark. I have tried the drivers from every link I can find on here and installed them manually. No go.
I also have the SDK which has the USB driver ticked and installed, but that does not seem to be helping.
Anyone know where I might find a driver that helps?
Ok seems I tried every single driver I could except for the one in the Asus install!
All good now and flashing

Need help updating my rooted HTC One S

Hi all,
I've had to root my HTC One S for school recently (yes, really), but now I can't install the update that's been released.
When I start the update my phone reboots and enters Clockwork..
I've been trying to unroot my phone, but there's a lot of (different) information out there, and I can't seem to put my finger on it.
For starters, I have no idea what RUU is and I have no idea which stock img I need, since their are more than 20 of them out there..
Can somebody please guide me through?
Thanks!
Tom
Edit: I can't seem to get a Android 1.0 USB driver working.. If I type adb devices it lists no devices.. I've tried like 5 different drivers but none are working.
Edit: My normal USB driver is working. ADB devices returns my device, but when I try to flash the recovery in normal mode, it just says 'waiting for device'.

help with fastboot.

I previously unlocked my bootloader, installed oxygen 11 (am on beta 4) . I want to install PA but I can't get fastboot on my machine. Shouldnt it be as simple as instilling adb and fastboot as well as the oneplus drivers? I've done everything I can think of and the majority of times ,I ended with an exclamation point in device manager and couldn't get the correct driver installed. I tried SDK etc.. more so... Android composite adb isn't showing in device manager. I might just use my laptop.
Any quick ideas on how to fix though? Thanks
There are lots of guides and links to the minimal adb/fastboot packages here on XDA. I will say it's a heck of a lot easier on Linux or even Mac, but typically the issue is that you want to have your device drivers installed first, then connect your phone (switch it between charging, file transfer, and MTP modes and let it install each of them fully to the device manager while it's plugged in), then install adb, enable debugging, plug in, run "adb devices" and trust the RSA fingerprint, and let it install that side of things to device manager as well.
I'd start by uninstalling all of the instances of the device in your system first to start over. You might even try plugging it in with no drivers installed first to see if it loads working generic drivers.
Man, I do not miss Windows.
I've done all that, and now I tried my laptop and it's the same issue. Adb works fine, mtp works, just fastboot says "waiting for device" so frustrated.
I'd switch to linux if gaming was better... You think most games can run in linux? I am used to use it in the last before I started pc gaming and I really liked how capable it was. Creating bash scripts for simple tasks was great.. Windows really does suck. Getting fastboot working shouldn't be this much of a hassle and it never has been so I don't know what's wrong. I've uninstalled drivers multiple times now and still can't get anything. I'm Wondering if it's this latest release of Windows...
Make sure you have the latest Android Platform Tools installed...

Try revoking all adb authorizations and then try to plug it in and run "adb devices" to regenerate an authorization maybe? Is the problem only with fastboot or is adb also broken? You are running fastboot commands in the bootloader instead of adb commands, right?

Any luck? I'm having the same issue. Just managed to get my phone unlocked from tmo, and for the life of me can't get windows to recognize my device in fastboot. After an uninstall of the device in device manager, and plugging it back in fastboot. It appears under other devices as simply android with a question mark icon top left, and a yellow triangle bottom right. Manually pointing to either the drivers from 15 sec minimal adb & fastboot google drivers, or selecting all devices>have disk>and pointing too the inf of the driver downloaded straight from google results in the yellow triangle going away, but the question mark still remains, and it's still listed under other>Android. So I suspect for some reason or another the drivers aren't installing properly. Usually (having to have to do this with other devices) has worked in the past. I've had win 10 mess up loads of things most notably my dl speed once. Some bug had it capped at like 24 kb/sec (shudders). Just for comparison what Windows version are you on?
Tried dl ubuntu to boot from usb and try that. Then I ran into issues dl the iso. Couldn't catch a break yesterday I guess. I'll try again after work today, and report back. Don't like the idea of having to boot linux just for fastboot. Might a vm, but I'm not sure that would work considering windows doesn't recognize the device to pass it through, but we shall see. I will say this just about over win10.
Also Idk if it matters, but I had Android studio installed before this as well. Might be time for a fresh install it's been a while.

Stuck on drivers

Hey so like i have a problem. It\s seems to be to simply impossible to get any drivers to work, i tried everything google drivers, sdk ,drivers that come on phone and drivers from some random websites. Nothing works, tried both w10 and linux ubuntu. On my older pc i had 0 issueas other than simply doing something dumb.
Im out of ideas, help? Also tried with sony z5 premium instead of my nokia 7 plus but same thing -_-
Sidenote:fastboot device from phone drivers kinda works(?) But still im not able to do anything because im stuck on waitig on devices when i want to flash
To manage an Android phone from PC you at least need
1. ADB - provided by Google
2. FastBoot - provided by Google
3. Android-USB-driver provided by OEM/Carrier matching your phone
and nothing else.
Have all of those and im stuck on waiting on devices after i reboot to bootloader. Seriously annoying maybe i will try on other pc and see what happens but its not really a solution
If your phone supports Fastboot - take note that not all phones do - then when Fastboot returns "Waiting for device" it's a driver problem: Install correct driver.
True but as i wrote official drivers don't work it's on the phone after all. Rest doesn't work too then . Heh
