I have a SM-T827V which has been working great, up until last night. At that time I pulled it out and opened the magnetic cover which normally wakes the screen. This time, nothing. I thought maybe the unit had turned off for some reason or hadn't been properly connected to the charger so the battery had died, so I held the power button to turn it on. The tablet vibrated and the "Samsung Galaxy Tab S3 powered by Android" screen appeared and sat for what seemed like at least a minute or two. At that point the device went black, vibrated again, and the same screen appeared. It kept doing this in a cycle, endlessly.
After a little online searching it seems that this is not a completely unusual problem with the Tab S3 and the recommended solution is to reflash the firmware. So I downloaded Odin 3.14.4 and the most recent Android 9 firmware from Sammobile.com, installed the Samsung USB drivers and put the device into Odin mode. Following provided instructions I ran Odin, selected the firmware files in the appropriate places (I used HOME_CSC rather than just plain CSC as I was hoping to retain my settings and apps) clicked Start and Odin went to work. It ran through some text output and ended with "<OSM> All threads completed. (succeed 1 / failed 0)" and the tablet rebooted. It vibrated and came up with a black screen with "Recovery booting...." in blue lettering at the top. Progress! Except now it just boot loops to that screen instead of the Samsung logo one.
I tried re-flashing with CSC instead of HOME_CSC. Same results. Tried booting with the SIM and SD cards removed. Same results. Tried re-flashing with the SIM and SD card removed. Same results. So, is there something else I can try or am I just completely out of luck?
Thanks in advance!
