Question [Q] Impossible to flash recovery img.

Hey guys, i've owned a G2 by Amazon.fr, a f320K version, Korean version from Hong-Kong, with V10E.

Then i updated stock rom many times until V20F , OTAs by the phone.

Second step. I easily rooted my phone by the Ioroot19 method. Sucess. Root_Checker is ok for my root.

Third step. Installing TWRP with loki patch.

But, i can't flash none of all the img files i tried (f320K.img, d802.img, d802K.img). Loki patch does not match my phone. Impossibe for me to enter in recovery mode because installation failed. If i want enter in recovery mode my phone said security booting error.

So, please, what i missed ? Or is because i'm on v20F ?

I joined a picture of my adb error.
