I am able to connect my phone (BLU STUDIO 6.0 HD) to my computer and use ADB, then type in fastboot oem unlock. However, when I try to use my Volume Up button in order to select to unlock the bootloader, it wont work. Only the Volume Down button is working, which cancels the command. I am doing this in order to get a custom recovery and in turn get CyanogenMod working. I've been working on this all day and have found no solution. :crying: I would appreciate any help.

So i was following these steps mentioned (developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/) hoping to unlock the bootloader...
It says i need to connect the mobile to the PC in fastboot mode by connecting the phone while pressing the volume up key...
But always it seems to enter in charging mode
I wonder if it does even work, so my question....
Has anyone of you tried it, does it work or is it still a dream to unlock the bootloader in xperia c.....?

Hi everyone! like i said, i've got this problem with my device; if i try to start it normally runs bootloader and then i can't choose any voice with the start button, only moving up (volume down doesn't work)... so nothing, only possibility is start in provisional mode.. i've tried to connect it with adb to make a flash of the bootloader but adb doesn't read the device even if the pc can read the archive... any solution??? thank you!
Hi there,
I think i bought a fake Samsung Galaxy S6. But it works well, and it looks identical and has most of the futures of the real Galaxy s6.
As a fake Samsung phone, it doesn't have any Odin Download mode in it. So i tried to get into the bootloader via adb "adb reboot bootloader".
When i get there, i try to unlock the bootloader "fastboot oem unlock".
On the screen of the Phone i get a message about the fact im trying to unlock the bootloader etc. Press volume up to Unlock, Press Volume down to cancel.
The problem is, I can't press Volume Up for some reason, only Volume down. So i can't unlock the Bootloader to install custom recovery via ADB and finally install custom ROM.
Anyone any help? I can only access Stock recovery menu, some chinese test menu and the bootloader. Thats it.
Any help would be appreciated, i can provide any info you will possibly need.
grtz, Alex
Hello, I came to this forums looking to get some help with a device that a friend gave me to fix. He tried to install some sort of custom ROM on his phone (Moto E XT1527), and after installing it, Im not totally sure what did he touch, but now the phone only boots up to a screen saying the following:
AP Fastboot Flash Mode (Secure)
BL: 80.0B (sha-2c9fcbc 2015-03-13 20:15:21)
Baseband: Not Available
Product/Variant: surnia XT1527 8GB P3
Serial Number: T00930M5JK
CPU: MSM8916 ES1. 0
eMMC: 8gb Samsung RV=07 PV=01 TY=57
DRAM: 1024MB Samsung S8 SDRAM DIE=4GB
Console [NULL]: null
Battery Ok
Device is LOCKED. Status Code: 2
Software status: modified
Transfer Mode: USB Connected

(There could be some sort of typo on it)
So far I have tried with a tool that suposedly would flash a ROM into the phone without typing any commands, but it failed at some point.
As for unlocking the bootloader, I was abble to obtain the code, yet when I try to unlock it via fastboot, it says that I need the permission to "Allow OEM Unlock", wich I can't grant because of the SO not booting.
Regarding to what my friend did with it, he's not sure, but he think he deleted some sort of file
Im not an expert on this kind of stuff, yet I can follow steps that are given to me to provide any info or to execute a fix, so I would appreciate any kind of help from you to diagnose and solve this problem
Thanks in advance
A little bump

it can be simply solved ....if you are able to boot to fast boot mode
HOW TO BOOT INTO FAST BOOT
First of all, you have to power off your Moto E.
In order to do so, press power button once and then select “power off” or keep pressing the power button for about 15 seconds.
Wait a few seconds until applying the next step.
After powering off your phone, press power button and volume down key at the same time.
Keep pressing these buttons for about 6, or 7 seconds.
Release the keys when the fastboot / bootloader mode is being displayed.
In fastboot use volume up and volume down keys in order to scroll up and down within bootloader menu and press power button in order to select your option.
if it enters fast boot mod unlock boot loaders ....when it says grant permission using volume up or down button
then flash a custom recovery ...make a factory data reset after you flash custom recovery .....
after all above steps flash any custom rom this will fix all your issues ... you can also try to flash stock rom images via fast boot

Hello and thanks for your answer. I have managed to get into fastboot mode, yet I still can't unlock the bootloader. It stills asks me to grant OEM permissions. Is there any way to grant it without booting into the SO?
Hi I'm hoping someone can help or at least point me in the right direction if i've missed a thread, i'm on Windows 7 64bit.
I appear to be stuck in a boot loop on my original Shield Tablet, stuck on nvidia screen when i try to go into recovery mode i get the "dead android" picture.
I have tried to unlock the bootloader and i get FAILED <remote: <>, device shows up under fastboot devices command, device shows up as Android Bootloader Interface in Device Manager.
I've searched the forums and seen this problem but everyone else seems to be able to unlock easily, this is the same but no replies https://forum.xda-developers.com/shield-tablet/help/nvidia-shield-unlock-bootloader-failed-t3178865.
Any help anyone can give me would be appreciated. Thanks in advance.
Check the recovery images section for your device here: https://developer.nvidia.com/shield-open-source
Instructions to unlock the bootloader:
Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.

You need to already have adb set up and the Shield connected to the PC to do this. If you don't have USB debugging enabled, this may not be possible, but you should still be able to get into recovery by booting the tablet with Vol- and power button (hold volume - and then just press the power button, don't hold both at the same time).
Yes I've tried that (I know the steps of unlocking the bootloader) that's when i get the FAILED error. When I try to enter recovery I get the "dead" Android picture.
