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.

Yunique stuck on cynogen Fastboot

When I flash recovery my yunique stuck on cynogen Fastboot mode:

Recovery means TWRP or Stock Recovery?
Incase You have not unlocked the Bootloader, the only way is Installing the Firmware.

Recovery option
Volume down + power key
Volume up + power key is for fastboot download mode.
Check it.
Make sure your bootloader should be unlocked.
If not you have no access to your phone
You have to flash stock rom using ets tool then unlock bootloader for access your phone.
Good luck

Did you unlocked your boot loader first? Or not? Before installing twrp. Tell me.

[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.

to install stock room is it necessary to go into fastboot mode or not. and if so then how can I install stock ROM because it enters into fastboot mode for 10 to 20 sec and reboot?

I've tried that already I even upgraded it to Android 11

Sometimes it might on boot up completely then few seconds after it reboots

Your phone's bootloader is misconfigured: it's the bootloader which tells the Android kernel what to boot into ( e.g. Fastboot, Recovery; Sideload, EDL, Normal ).
Try
Code:
fastboot devices
fastboot reboot
to have phone booting into Normal mode ( read: Android OS ).
