Mi max not able to boot up after flashing I successfully flashed my Mi Max prime 3/64GB to helium_global_images_V9.1.2.0.NBDMIEI_20171109.0000.00_7 ROM using mi flash in edl mode. Now the problem is the phone doesn't start up. It shows mi logo and android logo down the screen, its loading dots go for a few seconds, it vibrates and button lights gets on, and then it switches off completely.

I also tried going to recovery mode and wiped all data after flash. but it seems nothing works.

my device is not unlocked that's why I flashed it in EDL, and I prefer it to stay this way if possible.

any suggestions?
It turns out the problem is with the battery. the connector that connects the battery to the main board was damaged. so I guess it didn't provide enough output for the main board to boot the operatinng system up.
