twrp recovery not launching I installed a custom ROM two weeks ago, since then, i cant get to recovery mode, if I try booting into it, my phone get stuck on the oneplus logo.
I tried flashing it with fastboot,

C:\Users\juanhh\AppData\Local\Android\android-sdk\platform-tools>fastboot flash recovery recovery.img

target reported max download size of 442499072 bytes

sending 'recovery' (18964 KB)...

OKAY [  0.580s]

writing 'recovery'...

OKAY [  0.144s]

finished. total time: 0.726s

And also I tried flashing it with the TWRP app, it gave me an error telling that I have already intalled.

What is the problem?

Pd: I am not a native speaker, so sorry if i have a ilogical phrase.
You can reboot to TWRP using adb commands from your desktop.

Connect your android device, navigate your cmd to C:\Users\juanhh\AppData\Local\Android\android-sdk\platform-tools and type

adb devices


It will show list of connected devices. If not, then you probably need to install universal adb driver.

To reboot into TWRP recovery, type

adb reboot recovery
