I'm using OneUI 2.5 on Samsung A70
I have a Galaxy Fit e
I've flashed Bluetooth Library Flasher through TWRP. It said it sucessfully flashed
But when I turn on airplane mode or reboot, it still lost
My Fit e then reset
I tried using terminal, but got this:
a70q:/ $ su
a70q:/ # mount -o remount,rw /vendor
/vendor/etc/vintf` && [ ! -z $i ] && cp --preserve=all $i $i.bak && sed -i '/<.*security.wsm.*/,/<hal format="hidl">/d' $i
mount -o remount,ro /vendora70q:/ # i=`grep -lr 'security.wsm' /vendor/etc/vintf` && [ ! -z $i ] && cp --preserve=all $i--preserve=all $i $i.bak && sed -i '/<.*security.wsm.*/,/<hal format="hidl">/d' $i <
cp: /vendor/etc/vintf/manifest.xml.bak.bak.bak setxattr(security.selinux=u

bject_r:vendor_configs_file:s0): Bad file descriptor
cp: /vendor/etc/vintf/manifest.xml.bak.bak.bak: Bad file descriptor

Please help, what did I done wrong?
