I need help with my tablet

Question

My Asus fonepad8 is not turning on. There is no battery icon when I plug in the charger. ( I tried many chargers) 

I can't access, fast boot, recovery anything. ( I can hear a beep sound when I connect it to pc ) The phone is dead. 

I tried opening the back case and removed battery pins for 10 minutes but nothing.

It was fine this morning. The Android version was 4.4.2, I downloaded the latest version 5.5.0 ( From official store ) and updated it with sd card but the updating process was failed and shut down forever.

Hi Sanjai

I got your email, I do not have any suggestion. You already did a reset by removing the battery leads. That would have been my tip. I think the up date and your phone not working at all are kind of coincidental. It sound like it has something else wrong other than just up date problems or it would at least try to come on. My only suggestion now is get to a repair shop.
Good Luck Mark

It sounds like the 5.50 software didn't completely install.
I did a little reading on your Asus Fonepad8 .
There is a very detailed method to installing new software in your device.
Check out these websites.

From what I read on these websites,
They gave me the impression that if you don't follow thier instructions exactly  it could cause big problems.

The phone is completely dead, not even recovery. Need to visit service center

I'm not at all familiar with your phone model but, if was running KitKat,it's old. O thought I would mention a few things that can go wrong with an aged phone. Battery could be done. USB port could be damaged or dirty. Sometimes as well with older phones the battery leads are dirty or the battery no longer sits tight to the leads and is easy to check by slipping a piece of match book between battery and frame to make sure it's tight. Before you go to repair shop perhaps test battery to see if it holds a charge. One easy way to check this with things you already have is to clean battery leads with alcohol then strip end of USB cable and connect directly to the battery and charge.Pay close attention to polarity.
