Non-rooted OP2 turns on by itself and stuck in recovery mode

Hello all,
Just a heads up that I have little to no knowledge of modding/rooting phones whatsoever.
My phone decided to reboot by itself earlier today and was stuck in a boot loop for around 30 minutes before I managed to get into recovery mode. At this point it is still boot looping. Afterwards it just stop the boot loop and now stuck on recovery mode. Powering it off from recovery mode or by holding power button for 10s will only results in the phone rebooting itself into recovery mode again. I can get into Fastboot mode, however. Wiping cache and rebooting does not seem to do the trick as it would only go back to recovery screen after the OnePlus logo again.
Please advise on this matter

install drivers. connect to fastboot. Type "fastboot continue", this should turn on your phone but it's a temporary fix. Once it's on copy your data & perform a factory reset. - found it on oneplus forums (haven't tested by me)

Thanks for your reply, where exactly do i type "fastboot continue" ?

> First you need to install ADB & Fastboot to your Computer (Use This guide)
> Then Install Oneplus 2 Drivers (Use This Guide)
> Connect phone via Fastboot mode (Turn off the phone. Hold Volume Up + Power to enter fastboot mode. Connect phone to pc)
On the first guide (ADB & Fastboot) you'll find how to open a Command Window to issue fastboot commands. That's where you need to type "fastboot continue"

When my phone is in fastboot I don't see it on cmd "adb devices".

I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)

Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

Yeah, so I wanted to flash TWRP but it doesen't seem to work i did what was said in many guides but maybe if you tell me how to do it, it will work =) Thanks
So i tried to flash TWRP with the TOOL ALL IN ONE, everything was okey but then error happened called "Unknown device"

First of all, which version of G6 do you have? The US997 one, or the H870?

H870

For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.

Screen/Touch not working, trying to recover data

Hey, I have an XT1563 with an SD card integrated into internal storage (which I'm regretting deeply now). Never unlocked bootloader.
Long story short, the screen fried and now won't turn on. Now I'm on a long journey trying to recover the data from it.
I'm also a noob at all of this, here's what I've done so far:
I have the Motorola drivers installed, and just the SDK platform-tools installed.
I can't remember if I kept USB debugging enabled or not, but I figured if I could get it into recovery mode I could enable it through that.
But I can't enter recovery mode. The only thing I'm successfully able to do is enter fastboot mode. I tried doing a flash recovery but of course since bootloader is locked it failed.
So from fastboot, since I can't see the screen, I can only guess at which buttons lead to recovery mode. From images, recovery mode is second on the list, right?
I've tried Vol Down + Vol Up. Didn't work. Also tried Vol Down + Pwr. Also didn't work. Fastboot still says it's in fastboot mode and adb doesn't recognise anything.
The only way my laptop is recognizing the phone is through fastboot. When I plug it in normally it doesn't connect (guessing it jumps into charging mode, but adb still doesn't recognise it)
Can somebody help me here? IIRC Moto X Play does have a built-in recovery mode, right? Is there a way to enter recovery mode through CMD/fastboot functions, or can anyone help me with the hardware buttons to reach it?

I'm not sure what is possible. My idea would be:
1. Enter fastboot
2. Fastboot boot twrp
3. Use integrated adb of twrp to access data and shell as well as adb backup. Transfer data using data exchange for Android should also be possible.

Cannot go into the bootloader mode on my Galaxy tab SM-T285

Currently, I am trying to unlock bootloader using adb.
I installed adb and fastboot and checked everything until the CMD shows my device correctly.
And right after I type
"adb reboot bootloader"
my tablet just restart and does not go into the bootloader mode.
I also tried it manually, by pressing home+up+power button, but it also perform restart and no bootloader mode.
Does anyone knows why?
I checked all the settings in developer mode and cannot figure out why.

You can't unlock the bootloader with adb only with fastboot which doesn't work on Samsung. To unlock the bootloader on Samsung you have to enable OEM unlocking in developer options. Also Samsung doesn't have bootloader mode but instead they have Download mode which you can use tools like Odin or SmartSwitch to flash files. To get into Download mode use the command adb reboot download or use the button combination power + volumn down + home.
