Cant boot into bootloader - OnePlus 3 Questions & Answers

Hi, I flashed stock OxygenOS 3.2.4 via TWRP Recovery and I then I realized, that the stock Recovery was also installed. I tried booting into the bootloader and nothing happens only the led is shining white.
Hopefully someone can help me with the problem.

Can only boot into fastboot mode anymore

Hey guys,
I have a problem with my Z1C.
I used CM 12.1 quite a while now and I wanted to know how much difference is to Android 6.
So I downloaded the Remix Resurrection rom and flashed the boot.img in fastboot mode to replace the CM-recovery with TWRP. That was a bit tricky, because CM deleted TWRP again and again and booted in the CM-recovery.
So, finally I got TWRP working, after booting directly into the recovery after flashing the boot.img via fastboot.
TWRP now told me, that no OS is installed. I tried to wipe the phone and to install the RR-rom, but the recovery always said that it has the wrong version (?).
So I flashed the boot.img from the Cyanogenmod-zip and was able to boot into CM again. But now there seems to be no recovery on the phone. Whenever I try to boot to the recovery, the Sony logo appears and the notification light turns into orange, but then it starts again to do so.
At the moment I try to boot into CM again, but I think it has stucked in a bootloop...
What can I do here? The only thing what works is to boot into fastboot mode, but without the system.img I cant flash any roms there. How can I fix this?
Thanks!

Shut down your device and press volume up button while connecting it to your computer. Then it will boot into fastboot mode and you should be able to flash stock firmware in flashtool, and then you can start from scratch.

Another option is to follow this guide to install Recovery and When done you can boot into Recovery and flash a custom rom. http://forum.xda-developers.com/sony-xperia-z1-compact/general/fota-twrp-recovery-amami-t2909719

Try Rashr app from play store. It sounds to me like incompatible kernel/recovery combo. Download a recovery IMG, (latest TWRP, for example), then use Rashr to flash it. You can also use it for flashing a boot IMG. Its probably the same reason you had trouble flashing ROM.
Besides that, you can install real recovery, which works the same regardless of the kernel-

Okay, after flashing it with flashtool it starts again. I now put the RR rom with Android 5.1 on.
I have again the CM recovery, but at least it starts how it should.
I will try to flash the real recovery, thanks!
Update:
Currently running RR with Android 5.1.
I would now like to use RR with Android 6, but again, I can only boot into the Cyanogen recovery, which cant make a backup of the currently running OS. I have tried to flash the boot.img from RR 5.1 with fastboot, Rashr, but nothing seems to work, as it puts me back to the Cyanogen recovery every time. How can I replace the Cyanogen recovery?
And one more question: When the phone starts, the notification light turns into red before the Sonmy logo appears and then turns into pink. What does the red light mean?

You need a recovery img, not boot img. Try this one - http://forum.xda-developers.com/showpost.php?p=65361797&postcount=78 or this one - http://forum.xda-developers.com/sony-xperia-z1-compact/general/fota-twrp-recovery-amami-t2909719 Open Rashr, choose ' recovery from storage'.
Okay, i flashed the 2.8.6.0 version via Rashr and now Im stuck on the Sony logo...the notification light is orange all the time, but I cant restart the phone anymore...any suggestions?
Edit: Worked! Used the combination between power and Vol+ to reset, and now it starts!
You should disable CM Recovery Protection – On your phone go to Settings > Developer options. Then disable the ‘Update recovery with system updates’ option. Otherwise it will keep installing cm recovery itself.

can anyone help me? phone is stuck!

okay so i tried to flash a cypher OS rom on my sultanxda CM13 and my phone is currently not going into recovery so basically i am stuck in fastbood mode . my device state is unlocked and when i restart or try to go into recovery the phone just turns off and does nothing. the only way i can actually turn the phone on is by holding volume up + power + home (hard reset tactic)
can anyone help me?
so where do i go from here? i tried the toolkit unlocked and re-locked the bootloader, tried to flash stock recovery img, tried to flashing twrp, nothing works guys.
flash Original Rom
Make sure you're using latest modified recovery (28) by eng.stk.
From your description the phone most probably doesn't actually turn off, it just displays black screen (common issue caused by TWRP incompatibility).

You re-locked the bootloader while you were still on a custom ROM and/or recovery?

Stock recovery issue

Hi,
I had TWRP .28 recovery installed but it was unable to decrypt data, so I decided to flash stock recovery back via fastboot. Now if I try to boot into recovery I get the 1+ logo and after that the phone gets stuck in black screen. I tried to flash it again and same issue.
How can I get the stock recovery working again?
Same here. I got a boot cycle after the update of 4.0.1 and thought, reverting to stock recovery is a good idea ... NOT.
The problem now is the the same as you described it: black screen after the 1+ Logo.
When selecting the boot options (unlocked OEM Warning) i can go to fastboot, but the device is not found => no sideloading
Any idea

I managed to fix mine. Apparently the old stock recovery doesn't work with Android N. I downloaded open beta 8 recovery and flashed it via fastboot.

NEED HELP, CAN'T BOOT INTO RECOVERY/OS - One Plus 3

I was running an unlocked one plus 3 on OxygenOS 4.0.2 (Android Nougat) and have TWRP installed. As 4.0.3 got released yesterday, i tried installing it today but i accidentally hit install on the OTA update setting which caused my phone to reboot. Now my phone won't boot into the os, i get a black screen after 'powered by Android'. I tried getting into Recovery however i get the same response, a black screen. I do not think it is hardbricked as the Fastboot still works and when i go into fashtboot it states that the OEM is 'unlocked'. I have personal data on this device pls can someone help. I do not know what i should do> How do i boot into recovery without crashing?
Is it possible to install twrp again with the PC? I had once also the same problem, install it again and after that it booted again into recovery.
Just install TWRP from fastboot, then you'll have access to internal storage by TWRP
It's happening because it's trying to send you to recovery which is twrp 3. 0.4-1which is bugged so just go to fastboot and flash twrp 2.0.4-1 and then try booting in.. You can even update the phone by flashing the update zip by oneplus from recovery
