解决方案二:用fastboot刷boot.img和system.img
首先,试了fastboot刷升级包,报错:“error: update package has no android-info.txt or android-product.txt”(这个是因为机子是5.1.1的包,而升级包的结构升级了的原因吗?)然后,试着刷booting.img,报错:“FAILED (remote: download for partition 'boot' is not allowed)”(这个是因为没有解锁bootloader么?),再刷system.img,报错:“Invalid sparse file format at header magi erasing 'system'... FAILED (remote: unknown command)”
目前无解,遂上来求助。这种情况还有办法吗?
