The search button is your friend
When inside the bootloader, plug the tablet into the USB port on your computer. Then select recovery. That should solve the problem.

I had this problem also. Some people say that you don't need the drivers installed and you can use a USB port on anything, I used the USB port on my PC and it wouldn't let me select recovery until I installed the drivers.

Nexus Toolkit just hangs. Drivers installed.

I can't get the Nexus toolkit to work, it hangs when trying to update the program, throwing the device into Fastboot (device doesn't do anything but the program just sits there indefinitely).
I can't figure out what I'm doing wrong to get this thing to work. I'm in USB debug mode.
Use fast boot adb

Use Magic together with a external USB drive?

Hi all,
I'd like to connect one of my USB hard drives to my old HTC Magic. What would I need to do to make that work? I've read about host cables and host modules on the phone.
Anyone that could give me some pointers?

Hi,
I doubt that's possible with low effort, Magic doesn't have an USB host, it's only a client (like an pendrive) so I think it would be a huge hardware problem.
Additionally - to start an HDD You'll need an maximal current what an USB port can give (500mA), I doubt that Magic has this power.
I actually bought a powered USB hub to make it worked and was just about to create my own otg cable, when I bricked it when I tried to upgrade the radio.

No way to go to the recovery? Fastboot? Connecting with ADB trough the USB cable?
Look what I've found! HTC Magic USB HOST
Well, perhaps I should give it another go, but it's stuck on a screen with a package and an android with an arrow pointing the android into the package - or if it was the other way around. After a quick moment, the screen goes black... restart does the same.
So there is a way then

But, hmm You had some unstock rom or not?
Can You run the recovery or not? (Turn off Your phone and turn it on pressing HOME + POWER button)
If You can run into recovery, then there should be no problem
I were about to flash another custom ROM from CM6.1.
And I am unable to access recovery. I'm stuck on the radio flash screen.

Problem with USB Connection in bootloader

I have a USB connection in MAGLDR (USB Mass and USB Flasher) but in (Tri color screen) and Windows Phone - USB connection not work.
You probably need the HTC sync drivers.
Sent from my NexusHD2 using xda premium
Drivers installed correctly. The Problem is that windows does not detect anything in both modes. For all works perfectly in the MAGLDR
What does it day in device manager when connected in boot loader?
Try disabling any antivirus temporarily if all looks OK in device manager..

Might be worth trying to reinstall drivers and disable any anti virus plus external storage you may have. Supposedly cpuz causes conflicts at times however I've never faced this personally.

[Q] /system and /sd card formatted = no usb connection

Hi guys.
My frind is a newbbie and formated the system and the sdcard of his nexus 4.Since i have one, rooted, he asked for my help...
The problem is i can't get the windows to recognize the device. I've tried it in a different computer (one who never had an android device connected), and still nothing. Tried using adb and fastboot, and even tried the WUG toolkit, and nothing. When i connected it to the pc, it doesn't even make the usual sound of a new device being connected.
If the pc can see the device i can do the rest, but right know i need your help on this issue...
many thanks.
Anyone please...! Is it Bricked?
Since it doesn't boot into android adb won't work so fastboot is the only option. Just flash the stock 4.3 image and flash custom recovery after if he wants it

Stuck first time root

Hello,
This is my first time rooting anything. I have talked to several people and followed the instructions on here and it seemed pretty straightforward--Until I got stuck. I got the bootloader unlocked and the recovery is loaded correctly I think...but now my computer won't install the nexus 7 drivers that it already had installed, and therefore I can't load a rom onto it...I don't know what to do. I've tried installing the nexus 7 drivers multiple ways from multiple sites with no luck. This is a new device and I really hope it's still fixable. The attached picture is what I think is the recovery mode, which I can navigate in, I just can't communicate between my nexus and my computer. Windows 7 64-bit HP Elitebook laptop.
Thanks
You don't need the pc anymore.
Next step, reboot your tablet, and download the superuser binaries from http://download.chainfire.eu/365/SuperSU/UPDATE-SuperSU-v1.69.zip
Then reboot into recovery by holding down power and volume down together, install the superuser binaries, reboot your tablet, and you're done.

Or he can connect to his PC, use ADB and type "adb reboot recovery", just saying.

Unless, like the OP, you're missing the drivers (though how he got that far without them is a little hazy).

All of the correct drivers were there and it was completely recognized before the root. Now in device manager it shows Nexus 7 with a yellow exclamation point next to it and it won't show up in my connected devices. Because of this I can't connect from the pc. I don't know why the drivers worked and now don't. Also when I try to boot the Nexus 7 it stays on the Google 'X'

You're stuck in a bootloop.
Power it down for five minutes and then try rebooting into recovery again. Use the recovery to wipe your cache and dalvik cache. Try rebooting the system again. If you're still stuck in a bootloop, go back to recovery again and wipe data/factory reset.

Thanks Guys! Bootloop fixed it!
