I just unlocked my TF201 and tried flashing CWM with fastboot. I rebooted into recovery and selected fastboot, plugged my tablet into my computer, and then typed the command to flash the recovery, but fastboot just says "<waiting for device>".
I tried this on both Ubuntu x64 and Windows 7 x64 and they both did the same thing. What am I doing wrong?
EDIT: I figured out the problem. On linux I didn't use sudo when using fastboot. After using that, it worked just fine. I wasn't able to get it working in Windows, but that doesn't matter to me anymore since I was able to flash it.

Normally, fastboot is supported by mac with android sdk, but it doesn't find my phone when I connect it. Has anyone tried to flash recovery on a mac (I've already unlocked bootloader with adb reboot oem-unlock)? And virtual windows doesn't recognise ANY fastboot drivers. If only there was a way to flash that recovery image... (and, I suppose, adb push is not helpful this time?)

Nvm, solved it (with parallels 6 running windows 7)
I have recently been interested in wanting to install a ubuntu onto my tablet, so i am installing twrp first, i have downloaded the android SDK files and have extracted them with adb and fastboot into my c: drive, i have also unlocked my device by using the Asus unlock tool, i then when into the i believe its called bootmenu where you can choose between usb,rck,coldboot,ect and downloaded the fastboot driver into my usb 3.0 after that i flashed twrp using "fastboot -i 0x0b05 flash recovery twrp.blob" in cmd everything went well the blue bar loaded, the cmd said it finished.
Now this is where the problem starts when i enter RCK (recovery mode) it just freezes there like the fastboot, the icon stops flashing and text appears saying "booting recovery image kernel" but nothing happens. To my knowledge and the guide i am following it should boot to twrp if im not mistaken.
I am using windows 7 for my pc and have updated my tablet to 4.1.1, i have also check the Md5 codes. I am also following this guide (http://forum.xda-developers.com/show....php?t=2038464).
If anyone could help out someone trying to get into roms for andriod that would be awesome thank you.
Okay, so basically I am a HUGE idiot. My phone has been running the latest version of ParanoidAndroid and I decided that I wanted to try MIUI. I booted into TWRP v2.6.3 and wiped everything a couple of times before installing it, and I forgot to install the boot.img afterwards (it was s-on). So now everytime I turn the phone on, it is just always on the boot animation for an eternity, and my computer won't recognize my phone so I can't use fastboot or use an RUU. I am also unable to flash PH98IMG from the phone itself. Is there anything I can do to fix this? Thank you very much in advance.

Take out the battery, put it back together, power on the phone while holding down the volume down key til you get the splash screen, that'll boot you to the bootloader...
No I understand that, but there's nothing I can do from the bootloader. Once I get there, I can either go to TWRP or choose Fastboot. When I choose fastboot, it will say Fastboot USB after connecting to my PC but it will still not show up or be recognized (and I have the drivers). My only other options are Recovery (TWRP), factory reset (also TWRP), clear storage, simlock, and image crc. All I need to do is load the boot.img file, but it appears to me I have no way of doing that now.

Being seen in fastboot has nothing to do with the ROM at all, you need to troubleshoot this from the PC end. When you start fastboot on the phone and connect to your PC you get nothing? Not even a connect sound?

I do get the connect and disconnect sounds. Whenever it makes the connect sound, it doesn't show up under "Devices with Removable Storage." When I heard the connect sound the first time I went to the cmd prompt and typed "fastboot devices" but it showed nothing.

It won't show up as a drive at all in Fastboot mode, to see if it is connected properly go to Device Manager and look for ADB Interface -> My HTC, if it isn't there then your drivers are not installed properly. Drivers come from HTC Sync, which can be downloaded here: http://www.htc.com/us/support/content.aspx?id=6196 once installed and the connections in Fastboot and ADB verified to be working, HTC Sync can be uninstalled (the drivers will stay).
When you run "fastboot devices" you get nothing? Or do you get something like "< waiting for device >" or literally nothing?
What version of Windows are you running, you need to be on Windows 7 or older? Running under Windows 8 is not recommended.

Ah, that may be my problem then, as I am on a Windows 8 computer. I will try all of this on a friends W7 computer in the next few hours and report back with the results. And when I did fastboot devices it literally said nothing and was ready for another command. Thanks for the help!

You can also use a live Linux CD like Ubuntu and boot that and install the Linux version of ADB, it works fine.
Hi all,
I'm here because i don't know where else to look..
I've got a nexus 9 tablet running 5.1.1, its rooted with an unlocked bootloader, running twrp custom recovery, i was trying to flash a new rom, now all i get is a constant google logo upon bootup, I can enter recovery and fastboot and all of that, but none of my computers can see the tablet in adb or fastboot when I plug it in via usb, so Im not able to flash anything from my computer, does anyone have any ideas? or have I totally ****ed my nexus 9?
I have 2 laptops running Ubuntu, and my desktop is Windows 7 with all the necessary drivers, I've never had issues connecting my devices in the past, so I'm kinda at a loss.
have you flash all the .img file manually..if yes then try to factory reset first and see what happen..if no then you need to flash stock recovery and then factory reset..hopefully it help

Check your drivers in windows again.
Nexus Root Toolkit has a driver guide if needed.
Hope your not trying "adb devices" while in fastboot mode? Try "fastboot devices" while in that mode.

no, no, I know not to use adb devices while in fastboot, but I can put my tablet in fastboot, but any time I try to give it a command via my laptop, it just says "waiting on device", its like the computer doesn't recognize that the tablet has been connected...

change your cable connect to computer..some cable cannot sent data..happen to me

Can you enter recovery? If you can then use your computer to copy the zip file of a rom and install it. Otherwise check your cable, I had problems with the one htc gave me.
Hello all,
I am stuck in this problem. Would appreciate any help.
Working in LINUX ubuntu 18.
Got a MI pad 1 with locked bootloader.
flashed TWRP recovery using fastboot. Booted into TWRP successfully.
Flashed the files from this
https://www.techeia.com/2018/10/best-custom-rom-for-mi-pad-1-2018.html
Everything flashed successfully.
Rebooted only to be stuck into MI logo screen. Bootloop probably because of locked bootloader.
Hence, I decided to wipe the bootloader itself
got the hint from here https://forum.xda-developers.com/mi-pad/how-to/fix-fastboot-bootloop-fix-xiaomi-mi-pad-t4008653
but I didn,t wiped recovery. but erased everything else. Then powered off to boot into previously installed TWRP recovery.
From there, I am trying to boot into fastboot or TWRP but the screen is showing blank. I am using the key pattern for fastboot or recovery and trying to detect the device into any mode through ubuntu terminal using
sudo fastboot devices and
adb devices
but its not detecting the device there also. USB debugging was enabled already.
Any clues for how can I boot into fastboot or TWRP from this.
Regards
Hiteshkartik

A device with erased boot-loader never can work: you simly get a black screen. You no longer can communicate with it - neither via ADB nor via Fastboot.
Can I have a way around ?? I mean installing bootloader or somehow booting into fastboot or TWRP directly with any toolkit or terminal.
