Redmi 3 pro Hard Bricked

[Wikusaurus]

Hello.
last night i was trying to flash miui 8 on my device via twrp but it takes too long so the batery died, thats because i was using otg.
now my phone wont charge and wont turned on, no vibration, no edl, no fastboot, just blank screen.
but when i connect it to PC mi flash detects com 10, so i flashed twrp and succeded, but my device still wont turned on, i tried flashing official ROMS for redmi 3 pro, but failed, it said error in hello packet or something, sometime the error change to ping via firehouse failed.
anyone has a solution? i really appreciated it.
Thanks.

Edit: I've found the solution.
1. go into EDL mode by pressing Power vol+ vol-
2. use miphone 20151028, don't use recent mi flash
3. Flash TWRP
4. Proceed to flash ROM (in my case i use RR Os) via TWRP

bricked after battery change

Hello,
I had obviously a battery problem. So I ordered one from ebay and I replaced it. The new battery seem to work, however the phone will not respond to the buttons. Not any buttons. Only if I plug in a cable, mi logo appears for a few seconds and then a big battery bar shows for a few more seconds. Then nothing. (If I put in the old battery and I plug in a cable, the reaction is the same BUT no battery bar appears). Any help? Thanks, Filip.
