[Help] SM-N910T (T-Mobile) : Broke after MM Update



My note 4 was working fine (with Lollipop) until T-Mobile pushed the MM update. The device now has frequent restarts, random (frequent) freezes to the point that it has become unusable. It sometimes does not even restart unless I take the battery out and press the power button and try again - I have tried replacing the battery, using safe mode, doing a factory reset but the issue persists.

Now, I am getting the below kernel panic screen on bootups (2-3 times):
...
Kernel Panic
KRAIT INFO
Panic caler : ext4_handle_error+0x9c/0xac
Panic Msg :EXT-4-fs (device mmcblk0p26) : panic ext4_da_writepa
Thread : kworker/u8:32:9832
pm88841_rev :0x0
Wait...
Done...
UDC START

KERNEL PANIC UPLOAD MODE
...

Any indicators if it is related to improper install or is it related to any hardware failure - I am out of warranty and have no insurance for the device.
