[Q] Xperia Z2 failed to turn on shows redlight (only when charging)

When I connect my xperia z2 to the charger, it shows the red light like its charging then after a couple of minutes shows the sony logo and shows the battery icon then then the red light goes off and sequence continues. The phone is driving me nuts. I've tried using flash tool but the phone cant even get into flashmode, it gets into fastboot mode though but thats about it. I've tried different chargers but failed.
Leave it to charge
My device faced this a few times but eventualy it got into charging mode and i was able to bring it back

Well, the only thing which comes to my mind is try to flash the Rom via Flashtool. I had my z2 in this stagw after installing twrp.
Flashmode and fastboot should work so look for tutorials how to flash rom
