Can't unlock bootloader

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

Bricked Moto E 2015 (XT1527) - Won't boot

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

Click to collapse
(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?

[Completed] Alcatel Pop 4s root help

I recently bought an Alcatel pop 4s(the unlocked model at best buy)and want to root it. One click roots wont work so i started the hard way. First thing i needed was to unlock the boot loader. Here's my problem, when i hold the power and up button it will take me to the recovery menu and i select to reboot in to boot loader, by doing this the screen turns completely black unless i press the power button at which point it just reboots normally. I also tried using adb reboot-bootloader and it simply reboots my phone. I have also tried plugging in to the computer while on the black screen and again it reboots the phone. There's an option in recovery to enable adb which when i click just tells me to reset and i have and it remains the same after it reboots. I have OEM unlocking enabled as well as usb debugging but i am at a total loss. If someone could help me unlock my boot loader or simply get to it for that matter it would be wonderful. If you could help with a full guide on how to root my Alcatel pop 4s that would be amazing as there is almost absolutely no information about this phone on the internet, thank you.

Hi !
Here`s a long discussion about your question , have a look , I`m afraid that your device must be OEM unlockable otherwise you can`t unlock it

Help Please :)

Hello Friends
My Honor 8 is broken after power down due to empty battery.
eRecovery is not working
Phone is not rooted.
my bootloader isn't unlocked.
Is it possible to Unlock Bootloader from Sdcard?
Cant come in the phone to turn on usb debugging .

Is it possible ?

You can boot into recovery using EMUI Factory reset (keep pressed Volume Up and Power button, having previously phone powered down) - for this you don't need to unlock anything.

Samsung Xcover6 unlock bootloader (SM-G736B) before rooting

Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help

It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.

ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?

Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...

Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00

It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.

Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?

The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
