with a usb otg cable.
install philz on fastboot and copy 1 rom on your usb key and fash to usb support
work perfectly for me
I encountered the same problem. Worst, no matter how, I just can't unlock the bootloader. Hence I cannot even change my recovery. My /data, /emmc and so /sdcard cannot be mounted. Even though adb push is working but still cannot have access to those files.
Can anyone help? Please.
