Dead/bricked infinix hot 4 pro (x556) - Android Q&A, Help & Troubleshooting

A friend of mine gave me a rooted infinix X556 (Hot 4 Pro) to unroot for him
I actually had in mind to just flash it, knowing well that it'll take care of both the rooting and ROM issues.
But in the process checking the root, I got to know that TWRP Recovery was used for the rooting.
I later got it successfully unrooted, and I tried to get rid of the TWRP by flashing just only the Recovery, but it wasn't just going through.
My friend collected the phone and was using it, Having been wiped with TWRP.
But after some days later, he came back with the phone, as it can only boot to the TWRP (It was even showing in the TWRP that NO OS Installed). He got the phone into that situation by trying to use TWRP to do a factory reset.
So, when I later collected phone, The initial OS version that actually came with the phone was X556-H371A-N-170926V157.
But I successfully flashed X556-H371A1-M-160906V70 MT6737M, using flashtool 5.1640, After the flashing, the phone couldn't power on again, and that's where the bulk of the problem is now.
Now it seems the phone to have been bricked, Guys, Please, how can I succesfully unbrick it and bring it back to life?
Thanks in advance.

If you cant go into DOWNLOAD, RECOVERY, FASTBOOT IT MEANS THAT YOUR PHONE IS AS GOOD AS A BRICK NOW AND IT CANNOT BE RECOVERED IN ANY WAY WHATSOEVER!!

Really? But all of these were working before the flashing, and what actually baffled me is that the flashing I did on it went through and I'm just wondering what the problem could be.
So you mean there's no solution whatsoever to this?

It's not even showing any sign of charging when it's connected to the charger, but makes this continous 'disconnection sound' when connected to the PC.

Well, I thank God I didn't relent on my own effort by not giving up on the phone as you have already condemned it.
I later used Infinix Flash tool to flash the same firmware I flashed with SP flash tool, and now the phone is up and running well.
So, please, I'll urge you not to be too quick to jump into conclusions.
Thanks

Wow That's some serious effort by you, but the situation you made, confirmed that your phone was hard bricked!
As far as my knowledge went I considered the following facts mentioned on Quora.com and confirmed that your device is HARD BRICKED!
QUORA said:
Hard Brick: All your device does is showing you a black or grey screen and keeps vibrating without any display.
Sometimes all you see is the RED charging light, and nothing else on the screen.

What I only observed is that it's like the Infinix Flash Tool is a bit better than the normal SP Flash tool, because the same firmware I flashed, which made the phone dead, was the same one I flashed on Infinix flash tool, which later made it work.
All the same. I appreciate your efforts.
Thanks so much
