[sakura]

I have TRT-LX1. Phone loop, go to recovery (fastory reset) and reboot on 11%. Try testpoint and phone detected 9008 but when try flash board firmware not detected. I can't go to fastboot . Need flash by testpoint. I read other people problem not detect phone by DC Phoenix in 9008. How fix this?
