My OneplusX bootloops!

[dimxr]

Hey guys. Hope the new year will find you jolly!

So, here is my problem. My OneplusX which runs with SultanXDA's Cyanogenmod 13 with TWRP (Sultan-TWRP-onyx-3.0.2-3_2016-10-23).
I cannot make it boot since whenever I press the button to start, it shows the screen (check below) for approximately half a second, it vibrates for a tiny moment and then shuts dows and starts again and does the same thing in a loop.
The only way for me to stop this loop is unplug the battery from the phone's motherboard.

I cannot boot into TWRP and all I can do is boot into fastboot mode. I get the device recognised with fastboot devices, but that doesn't work, too, since it reports that the phone is locked.

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
64875585        fastboot

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [  0.487s]
booting...
FAILED (remote:         Device not unlocked cannot boot)
finished. total time: 0.490s

Ultimately, if it's not possible to make it work again, I would like to manage to pull some files from there, like images etc if that would be possible.

Thanks in advance for your help!

I had same problem once all I could do was reboot fastboot but since the bootloader was locked but luckily I found this thread https://forums.oneplus.com/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-x.417648/ on oneplus forums this really helped hope this will help you

So, I will not try to use the Mega Unbrick guide yet since it deletes every user data and I will keep that as a backup solution.

I tried using the Skipsoft Android Toolkit in order to unlock bootloader etc, but so far nothing has worked.
The weird thing is that it reports the bootloader locked (even though it shouldn't be since there was already TWRP on it), but by the time that I try to unlock it, it says it's unlocked, tries automatically to get back to normal boot and at that time, we start bootlooping again.
Here's the Skipsoft Android Toolkit report:

Are you ready to start? Type y[yes] or n[no]:y

Device mode detected: Fastboot Mode
Device Serial Number: 64875585

Checking bootloader state..

Device bootloader state is: Locked

Do you want to unlock the bootloader? Type y[yes] or n[no]:y

When prompted, Press the Volume Up/Down button to select Yes on the screen, then
press the Power button to Unlock the Bootloader. If it is already unlocked this
will just be skipped and your device will not be wiped.

Sending oem unlock command to device..

Device bootloader is already unlocked so no data will be wiped


Rebooting back to Android..

rebooting...

finished. total time: 0.002s

Being in the same situation right now. Did you manage to come out of it?

You can try to reflash a TWRP on it. And then boot on it.
Or Mega unbrick guide

Both not possible so far, since fastboot tells me with
fastboot devices
52541fca fastboot
a) FAILED (remote: Device not unlocked cannot flash or erase)
b) "oem unlock" and "flashing unlock" gives FAILED (status read failed (No such device))

Mega Unbrick Guide doesn't start by flashing via Fastboot.
You need a recovery tool on your computer.

Yep, did that, all executed fine and situation changed from boot-loop into stuck at boot. Still only possibility is to get into fastboot.
Edit: Managed to get into recovery and sideload the original ROM there. Back on track

Lucky you. There was no way for me to get to recovery. Something was wrong there.
The only thing that really worked in the end was the Mega Unbrick Guide. I've got my phone back on track and working.
Glad you managed.
