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?

I have bricked or atleast semi bricked my Folio and i dont know if it can be fixed. It began with damaged internal sd, so i try the format zip but no luck. May device have been like this 3 days now. I NEED HELP, AND YES I HAVE ASKED IN GENERAL SECTION. but i didnt get an answer for days. I need help by someone who can tell me how to set up fastboot. My folio boots i can get to clockwork recovery and i can get in to fastboot mode. I have working ADB on my computer. The install fails when recovery is writing boot.img iget this message: assert failed
write_raw_image("/cache/boot.img", "linux")
E:Error in /sdcard/FolioMod.zip
(Status 7)
It installs system.img fine. So i was thinking i could fastboot boot.img to the device and maybe it boots. So i put Folio in Fastboot mode,insert usb, and update driver, go to command prompt and write fastboot devices all i get is:
? fastboot
Is there anything special i have to keep in mind to setup fastboot for Folio. I used the fastboot that came with SDK. Do i have to add something more to .inf file for fastboot? Do have to use any special fastboot just for Tegra2 devices? Is my fastboot mode damaged? Please i need help i have waited for days in general section not one answer. Hoping on better luck here in the dev section
Are you on Windows or linux?
Normally if adb is working, fastboot should be working too. Just boot your folio into fastboot mode and connect it to your pc. Type 'fastboot devices', if something shows up you are fine (might be just a bunch of ???s).
Otherwise (on win) you need to modify the driver a little. There is a howto around here. I will add a link when I found it.

But I think if adb is already working, you will be fine. Just make sure you have a recent version of fastboot from the android sdk. Older versions are incompatible with tegra2 based devices.

I had entered the part to .inf file but havent done the echo part in command prompt, will try now. Its weird as hell all i get when writing fastboot devices is a ? fastboot. Its a windows Vista 32 im using and SDK 08. And when i enter this echo 0x955 i just get that its the wrong path.
I got fastboot working didnt know it could be ? fastboot when it was connected. I kept getting it so i tryed to send some commands and it got thru. **** so i have had it working for days. I have flashed the boot.img via fastboot and am now trying to do an advanced restore of a nandroid. Will see how it goes. If its not working can i flash system.img and boot.img? Will that work? Well atleast now i can flash standard recovery and send it to toshiba
Probleem Solved Thank you mblaster, you wrote it could look like this when writing fastboot devices: ?????? or atleast something like it so i thought maybe i am connected as my said: ? fastboot . So i tryed some commands and they got thru. So to anyone who tryes to install fastboot try commands. I was waiting for days(dumb, i know). So now im back and kickin, watch out
Moved to proper forum
Not quite sure what has gone wrong with my tablet but it seems that my recovery partition has been wiped (no recovery) and my boot.img has also gone.
What caused it:
I was installing Ubuntu onto my Prime and I got to the stage where I flash the boot.img. However, fastboot said it was sending the file, then writing the file and reported both "<OKAY>". However, I am not receiving a blue bar as other people say they do, yet I have done before when following the NVFlash guide (yes, I have all my blobs and things backed up).
Anyway, I have tried installing the Universal Driver and it seems to work (shows up in Device Manager). However, any commands that I send to the tablet do not seem to work (fastboot FLASH COMMANDS).
Commands I've entered: fastboot -i 0x0b05 flash boot prime-sdlinux.blob, fastboot -i 0x0b05 flash recovery twrp.blob
Also, "commands such as fastboot -i 0x0b05 erase recovery" result in: erasing 'recovery' ... FAILED (command write failed (Unknown error))
I'm really stuck and it's getting late, not sure what to do. Hope you guys can help me out.
PS: Not sure if this helps but, I cannot turn off the device. It constantly reboots just to hang at the Asus Eee Pad Screen or to hang at the Fastboot screen (when volume_down is held).
EDIT: After troubleshooting some more I have found that uninstalling the naked driver and letting Windows find a driver will actually allow me to send a reboot command (and it'll work). However, any fastboot flash commands do not seem to work. No Progress Bar appears and any commands sent after a flash command do not work (can't reboot after sending a flash command).
Hold the volume up while pressing the power button for about 15 seconds or until it vibrates then release them and it should power off for you.
did you make an nvflash backup?
else try
Code:
downloaded the latest Virtuous Prime ROM.
extract the ZIP file and pull the file called 'blob'
rename the file as boot.blob and move it to the TOOLS folder and open Command Prompt
from the TOOLS folder, type: fastboot -i 0x0b05 flash boot boot.blob
then type: fastboot -i 0x0b05 reboot
this should make you capable to go to recovery again
Open a command prompt; type adb push virtuous_prime.....zip /sdcard/
Wait until you get a confirmation message
Flash the rom like you normally do
Done
found this solution somewhere....
I do have an NVFlash backup, just not with me right now. Will test the above method first. And thanks for the method of turning it off! Although I know it's still on. Just in APX mode.
EDIT: Windows XP (run through VirtualBox on my laptop) seems to pickup my tablet in fastboot devices now. However, I'm still not seeing a progress bar after flashing again, and have the same problems as before (cannot reboot from fastboot). Still doesn't work. I've run fastboot through a native Windows 7 machine and a Windows XP installation on a Mac. Not sure what else I can try if fastboot isn't working.
EDIT2: It seems that I no longer have the error "FAILED (command write failed (Unknown error))" with certain commands.
First, you are in the wrong section, it should be in Q&A.
Second why didn't you try nvflash?
See this: http://forum.xda-developers.com/showpost.php?p=29204285&postcount=228
I believe the reason why fastboot is not working is because you are flashing blobs whilst using AndroidRoot.mobi bootloader.
http://forum.xda-developers.com/showpost.php?p=28875606&postcount=80
I believe you'll have to blobunpack the blob and then flash the raw img files instead.
That actually makes perfect sense! Would have taken me ages to figure out by myself. Thought it was perm-bricked until I got back to my NVFlash backup files. Will try it out.

I was in a similar situation until someone pointed me in this direction. Using BlobUnpack on both recovery and boot images gives you boot.LNX.SOS and Recovery.img.SOS (or similar names)
Flashing these solved my issues.
Yea, it worked. Thanks a lot for the help guys. Just takes one extra step to flash something now, kinda annoying, but definitely worth knowing that your tablet is brick-proof.
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.

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.

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 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!
Hey all, I just got a G90 Pro that I want to put a ROM on, but something is up with the fastboot. I have the drivers installed according to what I found online, but when I go to fastboot there is no response from the cmd inputs. Nothing even shows up when I check fastboot devices. Has anyone had luck with these phones? I can't even unlock the bootloader!

I have done this, but did it again just to be sure, and device manager recognizes the G90 Pro under USB devices, and ADB finds it, but when I do the 'adb reboot bootloader' the fastboot mode text is on the bottom, yet fastboot commands don't do anything, not even 'fastboot devices'.
Edit: Fastboot devices is recognized in fastbootd, but not regular fastboot, yet the other commands don't work.
In your case fastboot is located in Android's user-space, hence you run this command sequence
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot
fastboot <YOUR-COMMAND-HERE>
fastboot reboot

Fastboot reboot fastboot just brings up the fastboot command list. Assuming it's expecting me to try reboot bootloader.
That's really weird because your phone is running Android 10.
My info in settings definitely confirms that. Nothing seems to be working as expected though.
