Galaxy Tab A stuck in boot loop

[mathiasa]

Hi!

I have a Samsung Galaxy Tab A (2018) SM-T590 that is stuck in a boot loop after what appears to be a failed system update.
I am unable to turn the device off completely or boot in recovery mode.

The original problem was that the "Google Play Services" kept stopping and throwing errors on the screen. I tried clearing the cache for
related apps and when this didn't work I also cleared the cache partition from the recovery menu. None of this fixed the problem.
The device then notified about a system update which I started. After a reboot, the device got stuck in the current boot loop.

I have tried all button combinations to enter recovery mode, but all the device shows is the start of a system update and then it immediately shows an error and reboots again.
I have also tried to let the battery drain completely and do a cold boot, as well as let the device charge for a couple of hours, without any change in behaviour.

I made a couple of videos showing the current behaviour, the boot loop and the screen that pops up when trying to enter recovery mode.
When plugged into my computer, I can hear the Windows device connect sound when the screen with only "Samsung" shows up and device manager shows an MTP USB device, but adb doesn't list any devices.

Any suggestions on how to get this tablet running again?

Good afternoon. I understand that a failed update on your tablet can be frustrating. Here is something that can possibly help with this issue.

You can download Samsung Smart Switch to your PC or Mac by clicking the link provided here: https://www.samsung.com/us/apps/smart-switch/. There is an option under the More menu for Emergency Software installation. 

If the above does not allow the device to reboot, your tablet will require service. To have the service set up, please send your model and serial number to this PM Link, and I will be happy to further assist you.
