[Q] [A510] Can't see device on fastboot

Hello together,
first I wanna say sorry for my bad english...i'm still learning
I've got three days before the A510 from my cousin, with the note that it always hangs during the Acer logo. He said he wanted to make an update and after that it would no longer boot.
When I type "fastboot devices" in cmd, no model appears.
Drivers are installed,'ve tried different USB ports. Used as the operating system Windows 8 64bit.
USB debugging is probably not been turned on (according to statement of my cousins).
Does anyone know this problem and can anyone help me with this?
Is the first time that I have to do with an Acer device, so am really encouraging hose...
I just tried the whole on a Windows 7 64bit computer times. Now there stands the following things in cmd after typing "fastboot devices": "fastboot devices" a "?" then some space and "fastboot".
If I type "fastboot oem unlock" there are two pictures on the tablet and the message that I should confirm with Vol- and Vol+ to select ... but when I do, it says:
"SetUnlockMode: Error occured while unlock the device ..."
"Fastboot: Failed to set unlock mode"
Now I am even more confused than before ...
Thanks for the help!!!

Unlocked bootloader, no fastboot?

Hey guys,
Today I unlocked my TF700 using the Asus Unlock Tool however when I hold down power and volume down it only shows 3 icons (RCK, Android, Wipe data) and just says Key driver not found..Booting 05; Android cardhu=user bootloader <1.00 e> released by "WW_epad-10.6.1.14.8-20130514"A03"; "starting fastbood usb download protocol" in the left top. Why isn't there a 4th icon to boot to fastboot? I am running JB 4.2, I have a 64gb TF700.
Thanks for any advice

On 4.2 they hid (USB debugging, ADB) by default. Go into your settings menu and tap the "About tablet" 7 times and it will show up under Dev Settings. Or it might be tap on Dev Settings 7 times, one of the two.
You don't need the icon because it boots into fastboot by default in 4.2, but you need to enable USB debugging first. Also, your PC needs to have adb ver ...30 or higher for secure ADB (cmd shell command: "adb version"). If you only have ...29, download an updated platform tools (if key driver not found error while connected to a PC's adb daemon).

You must be mixing something up here, elfaure!
On 4.2 if you boot into the bootloader you ARE in fastboot mode by default. That's why you don't see a USB icon.

You caught my error before I could fix it. I have a bad habit of reviewing my posts after posting and correcting with edit because I can read them easier. It was ADB I was trying to refer to.

Thanks
Thanks guys, but if I am in fastboot already, why don't the fastboot commands work when I hookup my Infinity to the computer in, what you now told me, is fastboot? BTW I did allow USB debugging and I downloaded the Android SDK just yesterday

Lots of reasons might come into play. I've extensive trouble myself getting fastboot to work -- changed USB port, removed extension cable.... pff...
You need the tweaked drivers, by the way, and not the standard ones. The latter seem to have communication problems.

I cannot do fastboot commands. Please help, I've been doing this all day!

My device is a One Plus One. I've installed an ADB driver from here: adbdriver (some site I've searched up on google) (Is this even safe? I've never seen anyone use this link before or maybe it's new. It's not a virus is it?)
So once I've installed it, I've typed all commands such as adb while my device is turned on but then when it gets to where I have to press my powerbutton+volume down and then go into the recovery screen, I see "Cyanogen Recovery" or whatever but that's what it says. Suddenly on my computer, the ADB device disappears altogether and I cannot see my One Plus One storage anymore (it's connected and even If I unconnect and reconnect it's still the same). I believe I've unlocked my phone already before so is this why? I just want to make sure and type fastboot oem device-info but when I type that nothing comes up. I've been trying to solve this and I don't know what to do anymore... Is it because I've already unlocked my device (but even I'm not sure if it's still unlocked and that's why I'm trying to confirm it by typing "fastboot oem device-info" which doesn't even work. Help please!

Greetings,
Thank you for using XDA Assist. To get you the expert help you need, I'm going to move this thread to your specific device Q&A forum.
Good luck!

You need to boot into bootloader by pressing volume up + power.
Then you can use "fastboot devices" to see if your OPO is being recognised.
"fastboot oem device-info" only works when you boot to bootloader
ADB is not fastboot btw.

ADB does only work when your phone is booted to the Android system and USB-Debugging is enabled

Shield K1 Tablet isn't recognized by fastboot

Good afternoon everyone
I got my K1 for Christmas and I've been trying to root it for a few days but I can't get that far because I can't get the bootloader unlocked.
I've been following the guide based off of Nvidia's website
I've activated USB Debugging mode as seen here . Now once I've authorized the PC using the tablet. Once I run cmd in administrator mode I run
Code:
adb devices
I am able to get the serial and it says it's authorized. However if I go into Fastboot. if I check for devices it just goes back to the prompt, and if I try to run the unlock command it just gets stuck on <waiting for devices> (I've attached a screenshot here.)
At first I thought this was an issue with the OS/Drivers because I am on Win10 x64, and the shield drivers gave some error about driver incompatibility. So I loaded up a VM with win7 x32. However I am running into the exact same issue once I get to fastboot; the tablet just doesn't want to cooperate. I've booted into fastboot manually Where the options are:
Code:
[nvtboot] (version UNDEF_BUILD)
[bootloader] (version UNDEF_BUILD)
Device - locked
Continue
Fastboot Protocol
Recovery Mode
Restart
Poweroff
Nothing is recognized from there either. I've also tried multiple cables, since the Shield doesn't come with any. Anyways I've searched the older threads here for help but none of them have given me any luck. If there's something I can try I would definitely be open to hearing it and trying, I just don't know what the issue could be.
Thanks for your time everyone.

You have boot into the bootloader before being able to use fastboot. Just reboot your device and hold vol- during startup. The tablet will show some console messages, offering some options. If you see that screen, you can use fastboot.

Adb works in normal mode.
Fastboot works in Bootloader mode.
Reboot to BL and type "fastboot devices", if no device go to K1 and select "fastboot protocol". Select on/yes.

Hey there, sorry for my late reply, I've been swamped with work. I've tried your advice with no luck so far.
I can reboot to the bootloader, but when I select "fastboot protocol" I don't get to choose Select on/yes. it just refreshes the screen with the same options that I listed above. If you'd like when I get home I can provide a screenshot of my tablet so you can see the options, but I'm not getting anything like you described. Am I missing something?
Thank you for your time so far helping me.

Connect k1 to pc, type in cmd:
adb devices
adb reboot bootloader
fastboot devices
/Enable fastboot protocol on k1, type again/
fastboot devices
Give here screenshot from pc - all command/answers in cmd. @bob3rt

I had the same issue and lasted untill I tried different usb cable
Shield K1 connectivity is very sensible to cable quality
try others

Hey Sorry again for a late response! However the good news is that I got it working!
What I ended up doing was hooking up the tablet to my Raspberry Pi with MATE and running adb/fastboot there. I originally ran into the same issue, but since I was able to sudo fastboot everything was recognized and seemed to work fine. I appreciate all of your help, and I apologize once again for the late replies!

For those that don't have a Raspberry Pi to follow the OP solution (like me), it's likely that your drivers aren't up to date on your PC.
Go here... https://docs.nvidia.com/gameworks/content/devices/shield_flashing_from_image.htm
And follow the initial instructions in the introduction paragraph and get yourself NVIDIA CodeWorks for Android. Once downloaded and installed you'll then see the shield in your fastboot devices list.
:good:

Worked like a charm! Thanks.

How do I unlock bootloader on Alcatel A466BG?

Hi, I'm trying to unlock my phone so I can install Kali Linux on my A466BG. I've read a lot on the web but came to a problem. I've got Android SDK on my PC and installed platform-tools. My device shows up after entering "adb devices." I've enabled developer mode and usb debugging and OEM unlocking. My problem is...I can't unlock the bootloader and use fastboot. After pressing power and up volume I get into the menu (and I actually reset my phone to factory settings so I'll have more space) but I can't find bootloader. My phone shows up fine on my PC and under devices, but when I switch to the other menu (with reset options) it doesn't show up anymore. Not even under "adb devices." I tried entering "adb reboot-bootloader" but it just restarts and goes to the normal android phone screen. I tried "fastboot -i 0x1bbb oem device-info" and it says "waiting for device." I'm not sure how to boot into fastboot and unlock my bootloader. Or why my phone doesn't show up on my PC after pressing power and up volume. Please reply with instructions. Thank you

Hi, me again. I found a video on YouTube on how to install Kali Nethunter on Android phones. I got it and now I'm installing Metasploit. It's just the command line but that should work. Check You Tube on "Nethunter without root" if you want to know. Thanks

I'm back...Not satisfied with Nethunter on Termux. I would like to know how to root the phone and install Kali. Can anyone look at the above question and reply with how to root my Alcatel A466BG? I'll check back tomorrow. Thanks in advance!
