OS deleted and boot stuck at company logo

Serial no. [edited]

Hi friends, I am a HP slate 7 voice tab user. Once I thought to upgrade my OS. So I rooted my tablet ...unfortunately with king root . But then I discovered that there was no lollipop or marshmallow ROM  for this device on the internet and my recovery mode  or boot loader was not working after root ....also my Google Voice recognition didn't work outside the app i.e I was not able to change Google Voice settings. So I uninstalled kingroot but it's files never left my system ...thus I though that I should completely renew my OS to delete kingroot from the deepest corner.so I went to system files using ES file explorer by enabling root explorer and deleted system files then my tablet closed up and when I held the power button it got stuck at hp logo with powered by android. I know I did the dumbest thing but I was just super frustrated .

It doesn't go away until battery is dead 

..and I can't remove the battery.

So is it a trash now or useful , please tell a solution.

Can I go to 3rd party people for repair?

Ok, but as i earlier mentioned that my recovery mode did not appeared after rooting my tablet. so after root if i hold the power button + Volume up(+) it shows hp logo and" Powered by android"written at bottom..that is same as just pressing the power button only. But when i press Power button + Middle Volume Button, it shows "Product Mode" Written at center in blue font. Also when i connect it to PC it shows "Marvell DIAG Driver not installed" and "CDC Serial Driver not installed".Now, i can not go into recovery mode to use SD Card and cant use PC to do something.

i visited the nearest hp service center a few days ago, but they said that this model was not a success and its parts like battaries etc are not available. They were only talking about hardware.i only have software issue and all my hardware is working normal. 

so the summary is that tablet is stuck on company logo and turns off when battery is 0% , no other normal combinations work to get into recovery thus when i press middle volumne + power than it shows written "product mode" and nothing else ,not even the regular android bot. When i connect it to Windows computer i go to devices and printer and it shows a box with green light at bottom with a yellow triangle error logo , so i troubleshooot it and it shows Marvell DIAG and CDC serial doesnt have a driver.

I tried to install the drivers but it is not helping as i am not getting the right driver on the internet. Also other drivers claiming to be Marvell DIAG and CDC serial are not working.

if there is not a hardware issue , then i am sure that it can be repaired .please help!
