S7 Edge isn't turning on

[watomaigad]

Hello.
So, I recently updated my phone 2 days ago for the first time after 2017, and the battery ran out while it was updating, and then it was boot looping and kept getting stuck at 28%.
I decided to reinstall the os on it (I installed the official rom that the phone came with). At first, everything seemed normal until I plugged it and after a while, the led indicator was showing that it was still charging but after I unplugged it from the charger, the light was still on and the screen was completely black and unresponsive.
After a while, the light shut off and after that, it never came on. I tried everything to get it on again: tried hard rebooting, trying to get into recovery, charging with different types of cables and with wireless charging also, basically every combination that came to mind. When I used the wireless charger, it showed that it was charging, but no signs of life on the phone. Samsung support wasn't that much of a help either, they only asked if I used a cable that worked on it and if the phone was water damaged or had any cracks.

Any help will be appreciated!!!

How did you reinstall the OS?

How did you reinstall the OS?

by putting the phone into download mode

Connect usb (not charger) hold vol- + home + power, release power after 5 sec n continue holding vol- + home . If download mode appears flash phone with same csc firmware. If no downlooad mode probably battery or emmc fault.

Yeah nothing really appeared. So I'm guessing its emmc fault?

Or battery

Or battery

If its an emmc failed qualcomm cpu S7e , pc will detect as qualcomm 9008 port.

For battery you need to manually check battery voltage.

This same thing happened with my s7 edge 3-4 months ago.... i was installing some apps from play store... as usual the device was high at temperature..it turned off... for next a couple of days it was only rebooting when it was very pleasent at temperature... and sudden shutting down within minutes.. the last time it did not turn on but the blue light was on for 4-5 days until it decharged... when the battery fully drained it never accepted charging or turned on yet... i miss my s7 egde... i had many useful data saved in it.. i lost everything..
I know it was the cpu failure...

Looks like RAM failure. Heating phone's back side(after removing back panel with hair dryer for few seconds may help. Not a permanent solution, but for data backup.
