I dunno what you tried, but here's official ROM :

TABS8-50LC_LTE_VOICE_ROW_WW14_S000200_150121

Intel Phone Flash Tools 4.4.2.0

Drivers

- After starting PFT (Phone Flash Tools), go to OPTIONS, Tab GENERAL, and select "Force Sparsing".
- Put device to download mode - on powered off device, hold volume down + power on, it should vibrate, and show droidboot screen
- Connect it to PC, install drivers. In PFT, device will appear.
- Click BROWSE, select unpacked ROM folder, and file "pft_flash_lte_normal.xml"
- Press "Start to flash" and wait for finish. DOnt be alarmed if device restart several times... just be patient.
- After PFT flashing process, device will continue updating, also be patient. (in some cases is needed to disconnect it from PC in that moment, after PFT finish).
- After all done, device should reboot and start normally.

take a try ...

Log:


Also I have tried to flash a file repair BIOS Flash XML , Hanging on Normal Boot Mode
Could not open /sys/devices/virtual/blacklight

Received error is oem start_partitioning ,means ... cant make partitions

Try with other posted ROMs, if still the same error ... probably eMMC failure,
and, unfortunatly, no software/flashing can help ... hardware malfunction.
