Coolpad cool1 Android 6.0 /eui Not rooted/oem unlocked Usb debugging mode on. All usb drivers + Qualcomm drives installed. Also adb +fastboot installed+sdk platforms . Twrp website doesn’t have officially twrp recovery listed for cool1. Downloaded a unofficial twrp recovery image from from xda. Adb and fastboot commands works fines all the time. Reboots in bootloader and the same error repeats again and again Sending ‘recovery’… FAILEDstrong text also while rebooting in fastboot mode i have to physically press ‘volume up’ button to install packages. I thought of adb over wifi Commands Works fine until it comes to flashing recovery.img in fastboot where pressing ‘volume’ button up doesn’t works(the phone does respond to button to go in fastboot to accept the package). note: the fastboot ‘voume up’ confirm button works fine while over usb and doesn’t respond while adb over wife which is strange I have been Messing with this shit for 3 longs days note:2 my cable is bit damaged bit everything works fine transfering files and adb commands too work fine so I guess its not the cable note:3 in the device manager the all adb drivers works fine except one adb interface I tried adding manual a hardware legacy drivers,installs fine but says eror code 10 the device wont start. All screen cap + log errors in the images attached bellow note:4 my idea here isn’t install twrp with a different method but to find error in this setup and solution to this Method
