I cannot get fastboot to find my TF201. I ran the unlock tool tonight on my stock .21 prime. I have booted into fastboot usb download mode with the Power + Vol Down, wait for RCK to pass, then Vol Down to select fastboot then Vol Up to confirm.
I have tried under my native Ubuntu 11.10 x64 install and Windows 7 x64. Under windows, I removed my already installed SGS2 drives and replaced them with the Naked 0.61 Drivers as found here: [ADB/FB/APX Driver] Universal Naked Driver Beta 0.6.1. I rebooted Windows and tried again to no luck:
Code:
./fastboot devices
or
Code:
fastboot.exe devices
as per respective OS.
Each command just echos an empty line, any tips?
EDIT:
I just went for it anyway and it apparently flashed the recovery
Code:
fastboot -i 0x0b05 flash recovery recovery-clockwork-touch-5.8.1.8-tf201.img
but now I am sitting with a completed blue progress bar and am scared to reboot the device.
EDIT 2:
I took a leap and power cycled the device, looks like recovery is in and good to go. Looks like since we need to specify the vendor_id for our devices, the devices command, or anything else for that matter fails to work properly (fastboot reboot, fastboot devices, etc.).
Hope this will help anyone else having issues.
Thanks.
SOLVED fastboot does not find device
Would like to expand your answer!
i am working with asus transformer prime TF201
i had a problem (SOLVED) where fastboot would not find device.
Code:
<waiting for device>
i fixed it by specifying asus vendor id (in this instance i was flashing a new recovery)
Code:
./fastboot -i 0x0b05 flash recovery recovery.img
Hope this helps it took me 2 days to figure that out
PEACE!
Thanks!
I ran into the same issue where the TF201 was not shown as a device.
You saved me from hours of pain!
how ot change vendor id
I'm having the same problem; need to install twrp via fastboot, but windows does not recognize the device. I have 'waiting for device'.
Can anyone explain how to change/specify the vendor id?
EDIT: nevermind, the 0x0b05 is the vendor ID, I already did that but the problem remained. In the end I switched computers and this solved it.
I'm having a somewhat similar problem except I connect my Prime and I see a serial, but it's not the serial of my Prime. I run the command:
fastboot -i 0x050b flash recovery flatline_tf201.img
and I get the message that it copied successfully, but I don't see any blue progress line and when I boot into recovery, I get the triangle; presumably because there is no recovery image.
I've tried it from three different windows systems (2 64bit and 1 32bit) with the same results. I am also unable to connect via ADB.
Any suggestions?
My phone is HTC Desire. Using to enter fastboot to install 4EXT recovery but failed
I can use adb command form cmd.

But When I restart my phone and enter to FASTBOOT is shows FASTBOOT USB in the screen but nothing happen when I issue command "fastboot devices"

Hello,everyone.I've got a Sprint optik(zte v55) 7" pad coming with HC 3.2.
After I flash a modified kernel, Its usb debugging mode can't work properly and my pc can't recgonize it.
Before I flash the kernel, when I switched to usb debugging mode and connect to my pc(runing win7), v55 will display a icon in taskbar showing it's connected with pc, my pc will show a new driver that showing the dirs and files in v55's internal storage, and when I run command "adb devices", it will show v55 is connected.
now, all the above is not happening anymore.
The thing is : I use 'adb reboot bootloader' and 'fastboot boot CWMrecovery.img' to flash the kernel in, which means the adb.exe and fastboot.exe can work before I flahsed the kernel, and now they can't work.So I think maybe it's the kernel cause v55's usb can't work ?
Forgot to metion: now, when boot into android system or recovery mode, I can't use 'adb devices' to discover the device;when I boot in ftm mode(which I don't know what it is),sometimes 'adb devices' print 'xxxxx offline' , sometimes print 'xxxx recovery'.
when print 'xxx recovery', I use 'adb reboot bootloader' , v55 enter black screen with back light which seems in bootloader mode, but 'fastboot devices' and 'fastboot boot CWMrecovery.img' are not working.Very strange.

Can anybody know what should I do now ? My intention is to root and flash CM10 to v55,and can be recongize by my pc again.
The kernel I flashed into is in http://forum.xda-developers.com/showthread.php?t=1473555,kernel #60 for v55.

Hi, here are some things to keep in mind when using adb.
Be sure of the command you are issuing
Insure you are in fact cd'd to wherever on your pc the adb binary is located
Insure your jdk is included in your path on your pc
To make things easier you can always also add the tools and platform-tools folder of the android sdk to your path
Lets make sure you are properly set up first before you start flashing things randomly.
For more info, you should check Android's page on ADB if you would like. http://developer.android.com/tools/help/adb.html
I'm not sure if any of this is actually directly related to your issue, but it is nice to start with the basics.

Thank you for reply.
The adb command I use is install by v55's driver.Everytime I use adb, I always go into the driver's dir (C:\Program Files\ZTE Tablet V55 USB Driver) which adb.exe is in.
And this dir is in my path.
The thing is : I use 'adb reboot bootloader' and 'fastboot boot CWMrecovery.img' to flash the kernel in, which means the adb.exe and fastboot.exe can work before I flahsed the kernel, and now they can't work.So I think maybe it's the kernel cause v55's usb can't work ?

Ooook now we're getting somewhere, I think
Make sure when you send your fastboot flash command you send it like so:
Code:
fastboot flash recovery recovery.img
Replace 'recovery.img' with the actual name of the img, whatever it is.
Also if you are getting the device offline error try killing server:
Code:
adb kill-server
and then restart it
Code:
adb start-server
See if that helps.

I will try these command when I get home, thank u!:good:
"adb kill-server" and "adb start-server" works fine.They turn v55's "adb devices" from "offline" to "recovery".
And I run command "adb reboot-bootloader", it seems that v55 is in bootload mode.
But after that,I run command "fastboot flash recovery CWMrecovery.img",it returns '<waiting for device>' and stuck there.
Before I flash the kernel #60, I can run "fastboot boot CWMrecovery.img" to boot to cwm,so I think it's not likely be the driver's problem,am I right?

Sorry to take so long to reply. I think it is not a driver issue. Do you know if debugging/adb is even enabled in the ramdisk? This generally would have to be done by the dev who created the kernel. Speaking of that, have you tried to contact that dev for further support? For sure they would know more than me since I don't own the device myself. I just know enough to be slightly dangerous, lol

It's very nice of you to keep help me here ,thanks again:good:!
After keep trying in past two days, I found that in ftm mode adb is enabled, and 'adb reboot bootloader' truly made the device into bootloader mode.
On my win7 pc, It can't be recognized.I switch to my old xp pc,and install the driver come from other zte user,and then...fastboot works.
Now I have the v55 running CM10,Awesome!Thanks to all contributors.
Still, my win7 pc and xp pc can't recognize my v55 through usb.But it's not big deal now.I can use tf and wifi and other ways to transfer file to v55.

Oh wow, that is quite the ordeal, but atleast its something huh, lol
I wonder if you could run adb and fastboot commands in xp mode on your win7 pc?
I know there is a way to run programs in XP mode, its just been awhile since I've done it.
And its no problem to keep trying to help, even if I don't know the device and all that. Maybe I can learn to while we are at it, and maybe make a new friend along the way
I used "adb fastboot bootloader" command, installed Nexus Google Galaxy fastboot drivers and got into fastboot mode today--maybe (See screenshot. Installed FB drivers after yellow arrow).
I know very little about fastboot mode. When I've used it with FB cable I first see a logo on tablet screen, and fastboot output appears on tablet. This didn't happen with adb fastboot command, the screen stayed black. Also, adb devices and fastboot devices commands both returned the same device number. I've always seen different numbers from those two commands.
Still, the fastboot commands I ran seemed to work. So my questions:
Is adb fastboot different from "real" fastboot?
Why no output on tablet screen?
Do we know for sure the bootloader is locked? Is there any possibility that "fastboot oem unlock" would actually work?
Has anyone here tried it?
(Sorry, no, I'm not gonna test ) Thanks for any info.
Fastboot Cable doesn't work: Maybe everyone already knows. I knew my old one wouldn't work so got a brand new one--and nothing.

I'm trying to test a twrp recovery I ported to my phone, but fastboot isn't working correctly. Adb works fine, adb devices shows my phone. Windows device manager shows adb composite device, all is well. Adb reboot bootloader puts the phone into fastboot as it should. Device manager then shows android boot loader interface. It should be working since it seems like the appropriate drivers are loaded, but fastboot devices gives me a blank line. Fastboot reboot just shows waiting for device and never gets any further. What am I missing?

Hello men.
Did you get the fastboot to work?
I'm in the same situation here.
Thanks :fingers-crossed:
I am on an older macbook pro running High Sierra. the phone I'm using is a Blu G5 running android 9. I have the developer options unlocked and oem unlocked and usb debugging checked. When i open my terminal i type cd and drag and drop the platform tools folder into the terminal window changing the directory to the folder containing the adb and fastboot files. I can use adb commands such as adb devices and get the serial number and it says devices. So far so good. Then i reboot the phone into the bootloader manually or using command adb reboot bootloader and the phone goes into fastboot mode. I know because it says it on top of the screen in white letters. Then i run into the problem fastboot commands don't work. If I type in fastboot devices nothing but a new command line shows up. When i type in any other command like fastboot device or fastboot oem unlock it says "waiting for any devices." I wait and wait but nothing happens. I have looked on the internet for a solution but all i find is that the driver may not deinstalled properly. I have tried manually installing fastboot driver and used sdk manager to install the fastboot driver and I have tried it using the terminal in android studio but no matter what when i try useing fastboot commands i get the "waiting for any device" message. Does any have a solution or could anyone recommend and forum for android development on MacOSX?
@DimDreams
Seems the Fastboot driver is invalid.

I have literally tried like 10 different sdk tool downloads just platform tool download basically every thing i can find. By chance would you or anyone out there have a working driver for MacOSX 10.13.6? or link a guide that can help me figure this out. I have made a little progress with a forum on xda about fastboot on macs but i still just keep getting the waiting for any device message.
@DimDreams
May also be that the Fastboot Android mode is not available on the phone in question.
I've had similar issues before and noticed that fastboot mode works better via USB 2.0 than USB 3.0. Maybe check which port you're using and switch. ADB seems to work well either way, however. Hope that helped.
I just had this problem as well and I found this, what worked for me is first boot your phone into bootloader mode with
Code:
adb reboot bootloader
. While in the bootloader fastboot worked for me. Hope this helps someone!
