I have a Samsung tablet (SM-T580) that apprears to be bricked. I let it run down to about 2% battery, and now when I try to charge it the indicator doesn't move and the screen flickers. I can't power it on. One time I tried it said "INVALID KERNEL LENGTH", but usually nothing happens at all.
I installed Heimdall on my laptop, and I've been looking for a firmware file to try to re-flash it with, but all the sites I can find seem sketchy (e.g. direct to some fileshare site for download). Anyone have experience with this who can help? I'd totally install a 3rd party firmware if it works and is trusted.
