in fastboot mode up volume key not working? - Android Q&A, Help & Troubleshooting

Its not broken as it works to boot up into recovery. I am trying to unlock the bootloader on my blu studio one S0110UU. "Fastboot devices" shows my device so its connected properly Any help would be greatly appreciated. "Fastboot oem unlock" shows the confirmation screen but only the volume down button seems to work and get a response.
Also when trying to sideload in adb or flash in fastboot I consistently come across the error "Could not find "META-INF/com/google/andriod/update-binary in the zip file" Am i not using the correct file or something?

[Q] 10.1v Device not found

Yes, I have read every single thread about this issue and I have tried all steps including downloading new drivers, removing old USB drivers, ...
Yesterday I unlocked my Bootloader using this thread: http://forum.xda-developers.com/showthread.php?t=1064793
Everything went fine and when I boot up my tab I can see the unlocked lock.
According to the thread the next step was following this thread: http://forum.xda-developers.com/showthread.php?t=1079781 (How to get root on 101.v)
I booted my tablet by holding down the Power Button and the Volume Down button. I selected the USB icon and in the left corner I see
"Fastboot USB download protocol"
Bootloader version: P7100BUKC8
Baseband version: P7100BUKDF
Lock state: unlocked
Everything goes well up to the step where I have to type adb push skitzandroid-10-1v-root.zip /sdcard/ in the Command line. When I type this, I get a message: "Error: device not found"
In the aformentioned thread someone else has a similar problem. One person asked if he was still in fastboot? Aren't you supposed to be in fastboot to root your device? He also asks if Clockworkmode is loaded. Doesn't this step come after rooting your device?
When I just open command and type fastboot devices I get a message saying: 'fastboot' is not recognized as an internal or external command, operable program or batch file. When I type "cd "C:\android-sdk-windows\tools"" and then "fastboot devices', it does work and I get a message saying: [serial number] fastboot. Does the fastboot devices command only work if you have a specific folder selected?
This is all so confusing
Thanks for any help
Thanks for the help

I cannot get fastboot to detect my device.

I have the Huawei Ascend Y300-0151 and am trying to unlock the bootloader, in which I cannot get through their website because it's really buggy and won't accept my information.
So these are the steps I've taken:
- Download SDK Manager and install platform-tools and Google USB Driver
- Boot my phone up and connect to the PC
- I can run the command 'adb devices' and my device shows with a unique ID.
- Boot my phone into recovery/download mode (purple screen).
- Connect my phone, the PC detects it.
- However, when I run the command 'fastboot devices', nothing shows up.
Yes, I have installed a driver for my device and it's now showing as Android Bootloader Interface.
I've run out of ideas and have been googling for answers for a very long time, but to no avail.
Any help would be greatly appreciated, thanks!

Given that your attempting to unlock the bootloader of your Huawei device, you should probably send an email to Huawei support requesting for your bootloader unlock code (thats what I did and they replied asking for my device information, and I gave it to them to which I then got my unlock code). For ADB to work you need to boot into fastboot mode, not recovery, then simply use the bootloader unlock code with the following command in cmd: fastboot oem unlock <insert your code here>
And then your done. Be cautious when unlocking your bootloader as you should make sure you have your developer options enabled and the "allow bootloader to be unlocked" option enabled as well.

I have e-mailed them 2 weeks ago and they are not replying. You're meant to do it through their website, but as I've said, I supply the correct information and it either re-directs to a page that is not there or says I am not entering my information correctly when I've done it over and over again.
The purple screen is fastboot mode isn't it? Because that's the screen I'm entering the commands in, but it's not showing up. I cannot enter in a code for fastboot oem unlock because my device will not be recognized by fastboot in the first place.
So before I am to unlock my bootloader, I'm trying to get my device recognized by fastboot.

You can send them an email to get the unlock code, trust me, thats what I did. Maybe try contacting them via their support section of their site if you didn't do so last time.
By the "purple screen" do you mean the screen with options such as "HBOOT", "Fastboot", "Reboot" etc.? The "fastboot devices" command should work if it is recognised by the command "adb devices"

I'll give it a go again, thanks.
By purple screen, I mean holding down the power button and both volume control buttons and the screen boots into a purple screen. Just a purple screen, that's it. I can boot into two other modes by holding down the power button and the volume up button and another by holding the power button and volume down button. I don't have a boot mode that displays any options as you've listed above.
EDIT: I'm in fastboot mode now! It was the mode where you hold down the power button and volume down button. Hahaha. I'll let you know how I get on with unlocking the bootloader. Thanks for your help
No problem, if you found my replies helpful please press the thanks button! It is much appreciated!

Newly rooted Moto G4 cannot enter bootloader or recovery, please help!

I am very new to this, I rooted my Moto G4 and now I need to download SUHide in order to play Pokemon Go. When I try to enter recovery via my fastboot/abd folder I get a < waiting for any device > message. When I hold down the power + volume down button my phone just turns on as normal without entering bootloader even though my bootloader is unlocked. I tried downloading an app that loads recovery for me but when I tried that I got a "no command" screen with a little green robot.
From what I've read, it's possible I didn't flash my trwp properly? I don't know how this is possible since I just rooted my phone. I would appreciate some help, I'm afraid to take any random guesses at the risk of ruining my phone. Sorry if I'm missing something obvious or not giving enough info, I'm not very tech savvy.

Try power plus volume up button to go to fastboot mode.
If it not working then connect your android to pc and enable adb. Type "adb devices" enter then type "adb reboot bootloader" and enter. It boots your android in fastboot mode.
If adb commands not working then install adb and fastboot drivers and try again.

In most devices, volume up + power boots up the recovery options, volume down + power boots the device into fastboot mode (volume buttons first plus power, pressing power button first would boot the device normally).

How did you install the custom recovery? Try flashing the recovery.img again (I'm guessing, since you have root, that you did not "flash" (fastboot flash recovery recovery.img) TWRP but just "boot" (fastboot boot recovery.img) it and installed SuperSU).

Okay, so that did work, and I was able to enter fastboot mode. However, once I scrolled down to "recovery mode" and tried to enter, I got the same "no command" screen.

I used the official moto g4 root guide on this website to root my phone and I'm pretty sure I booted, not flashed, the recovery img (mine is named twrp-3.0.2-0-athene). So, I tried using the command you provided to flash the recovery img and I got a < waiting for any device > message in the command prompt. My phone is plugged in and my recovery img is in the adb / fastboot folder. Any idea what this means? Thank you for the help guys
edit: If it helps to know this, my phone has usb debugging enabled and it is recognized by my pc. I type adb devices and my moto g4 serial number does indeed show up.

If you are trying to flash twrp recovery on your android then rename your twrp to recovery.
Boot your android in fastboot mode,
Navigate to folder that you have recovery. Press shift and right click and click on open command here and type "fastboot devices" and enter
"fastboot flash recovery recovery.img
It flash your recovery to your android.

Did all that, getting:
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
(bootloader) has-slot:recovery: not found
error: cannot load 'recovery.img'
Also, per the suggestion of other users on these forums, I tried to hold down power and press volume up during the "no command" screen after attempting to enter recovery. That sent me into Android Recovery but it's not the twrp platform I used when originally rooting my phone.
How did you unlock the bootloader? have you tried: fastboot oem unlock?
You need to "allow oem unlocking" on developer options (which I guess you already did). Then reboot in bootloader: (a) adb reboot bootloader. In fastboot, you need to unlock the bootloader first: (b) fastboot oem unlock (or unlock-go). Then you can try to flash that recovery.img: (c) fastboot flash recovery "name of the file.img"
edit: fastboot oem unlock restores the device to factory settings. You need to configure and enable again "usb debugging" and "oem unlocking" (which are disabled by default). You can then proceed to fastboot flash

Lenovo x103f unlocking bootloader issues

Hi guys,
In the past days i've been troubling my head with trying to unlock the bootloader on my lenovo tb-x103f, but cant seem to enter fastboot mode
I've been using this guide as reference, among other searches from all around, trying to work around this, but cant really seem to come to the bottom of this.
from cmd
adb recognizes my device
"adb reboot bootloader" tablet just boots into the startupscreen
"fastboot devices" somehow "confirms" that im in fastboot, even tho Im acctually not (right?)
"fastboot oem unlock-go" finishes, and says its successfull, but nothing happens (obviusly, since its not acctually in fastboot mode)
from there it just sits there, and nothing happens. have to reboot it myself, either via cmd or the button
why is it not entering fastboot mode? is there any fix for this?
This is getting really frustrating as I just wanna root the tablet and most likely install lineageOS, or some other custom ROM..
thanks in advance
If you can reboot it with a command than you are connected in fastboot mode. It sounds like you have unlocked you tablet. Enter fastboot mode through adb again and try "fastboot oem device-info"

Honor 7: flashing recovery

Hello,
USB Debugging is on
Bootloader is unlocked
HiSuite is up to date
Correct ADB Drivers are installed
and my device is recognized in both "adb devices" and "fastboot devices"
The problem: I'm trying to flash a TWRP recovery, but I keep getting the error "Failed (remote: Command not allowed)".
I don't know what's wrong, and I don't see any other way how I'd be able to flash a custom recovery. I'm trying to get my phone rooted ASAP.
I also get the same error when I type "fastboot oem device-info" for example, it's so weird I get so frustrated by phones sometimes :silly:
Hope anyone can help me out
Oh and I own a Huawei Honor 7 (PLK-L01 aka plank)
*BUMP*
Anyone who can help me out, please?
