I have the twrp, the problem is that it is in bootloop, now I was able to get the phone to be detected by the pc in fastboot mode, but I don't know how to continue, is it possible to install a rom via fastboot?

No don't, just grab the stock boot img and flash in fastboot. It will get you out of that. Don't reflash twrp. Not supported yet on A11

Not able to get to fastboot (vol+ and power). phone only boots into stock recovery. adb sideload works. installed stock cm11s via that the installation was successful but rebooting the phone takes me back to Stock Recovery (CyanogenMod Simple Recovery). This is a defect and OnePlus should be replacing my phone but, they are being very slow to respond, so I'm looking here for alternative solutions. It's a beautiful phone, but it just doesn't work

I never had such an issue so wait until more savvy people chimes in. Anyways it is really strange
hope so
Hmm. Not getting into fastboot is weird indeed..
Did you try another recovery? Did you try to adb reboot into booloader (fastboot)? Maybe the volume up button is not working..
Actually it looks like I may be in fastboot, but fastboot devices doesn't show anything. I tried the ColorOS install method in this thread, http://forum.xda-developers.com/oneplus-one/help/wrong-kernel-black-screen-fastboot-adb-t2835696 and looks like I've installed ColorOS, but instead of my previous problem, now I am stuck with a ColorOS Recovery Bootloop

When in fastboot does your PC recognize the device? Maybe you need drivers.

Revert from OxygenOS to Cyannogen - problem with recovery

Hi,
Last month I've successfully switched my Oneplus One 16Gb to official Oxygen OS 2.1.4
Finaly I prefer the Cyanogen version and here I have a problem with the recovery tool.
I can't replace OxygenOS recovery at all and with it : not possible to install "super su" or cyanogen 12.1 rom.
With adb the installation of TWRP recovery or or cm12.1 recovery seems to work fine (transfer ok and no errors) but when I restart in recovery mode ((power + volume down) It's still OxygenOS Recovery in my phone.
Please help, I don't want to be stuck in this state :crying:

download the latest COS12.1.1 factory image to your pc, boot into fastboot mode and install the factory image via fastboot (flash aboot FIRST and do a "fastboot reboot bootloader" before you flash the rest ).
After that (or during, just replace recovery.img) you may install any custom recovery

Yes :good:
You brought me on the right track
I have successfully applied this method.
I nearly lost my phone because I had a power outage during the recovery but finally all is fine : I am back on COS 12.1.1 :victory:
A big thank-you

Yes I am trying to flash TWRP
However, when I follow the below mentioned steps this is what i end up with :
List of devices attached
dc1c2a16 unauthorized
C:\Program Files (x86)\ClockworkMod\Universal Adb Driver>adb devices
List of devices attached
dc1c2a16 device
C:\Program Files (x86)\ClockworkMod\Universal Adb Driver>adb reboot bootloader
C:\Program Files (x86)\ClockworkMod\Universal Adb Driver>fastboot devices
C:\Program Files (x86)\ClockworkMod\Universal Adb Driver>fastboot oem unlock
< waiting for device >
And on the device screen it just reads "Fastboot mode"
So I kind of have the same problem but not exactly, I flashed the oxygen os and it worked perfectly but I wanted to change it to a nugget based rom and realized that I can not even boot into recovery. it gets stuck on the first oneplus logo that comes up and will not boot into the twrp. Any suggestions?
wait, so ur phone can't boot into the rom? or stuck at the fastboot mode everytime u try to turn on the phone ? I'm having that problem too, but I reinstall all the driver, and it worked.

My device is just stuck at the Fast boot screen that shows a One Plus Logo under which "Fastboot Mode" is written after I try to boot into fast boot.

Go to fastboot and flash latest twrp first. If you are rooted, you can do that also from running systen (flashify, twrp manager)

Thank you for your response. I tried doing that but it gives me an error saying that there is already a twrp installed. I used Twrp Manager

Yes, this is general procedure for any android phone. The only requirement is unlocked bootloader.

Fastboot loop oneplus 6

I really have no clue how I got here but i had everything going well and then there was an oxygen os update. I installed and lost root functionality so I did the whole twrp install thing all over again which was a mistake. I got stuck in a twrp boot loop and now im stuck in a fastboot loop. I have tried to sideload a stock image but it says phone is not in adb mode.... Help!

Try fastboot install Rom from here. Match the version you last had installed. Give it few minutes to get going once you start the process.

I'm in the exact same situation as OP, only my phone is a OP6T @david.baquerizo did you manage to install the fastboot Rom without problems? I'm wondering how it will be able to install if you can't see your phone in fastboot. My plan is to try different computers and go into windows testmode in order to get fastboot access to the phone. If I'm able to do that, it should be possible to flash a twrp.img and get back into action (fingers crossed)

[Resolved] Phone boots to fastboot Instead of recovery

Hey guys,
I wanted to flash a custom ROM on my Mi 9 SE, for this I installed TWRP (3.3.1-3) and Booted into it normaly. After wiping the phone I mistakenly restarted it and now the phone instaltly goes into fastboot mode without a chance to enter TWRP. I tryed to reflash TWRP but it did not work. I can't use adb as the phone only enters fastboot mode. is there another way to enter recovery mode? I also found the software MiFlash from Xiaomi but I only get the error "can not found file flash_all.bat"
Edit: Got it to work now, this is what I did:
Download MiFlash (from here: c[DOT]mi[DOT]com/thread-1329226-1-1.html [can't use links as new user ¯\_(ツ)_/¯])
flash stock ROM (from here: xiaomistockrom[DOT]com/xiaomi-mi-9-se [same])
it did not work with the stock ROM found on Xiaomis Website but only with the one linked.

Did you try booting into recovery using hardware button combo? That might help, I guess.
