Every time I flash new rom for my lenovo A 7000 a I always got this error but it install complete And after I reboot the phone I got stuck in TWRP boot loop I use lastest twrp twrp-3.3.1-0-aio_row The rom I use to install is LINEAGE OS 15.0 For A7000 [AIO-ROW] If i flash the stock lolipop or marshmallow rom via sp flash tools it become normal. But If I flash any other rom via twrp it stuck at the same problem

fixed you need to use boot.img from the rom to flashed again via twrp

after you flash the rom you need to flash the boot.img that in the rom folder only boot.img

Sorry my english is not good !
