Crucial Warning: Verify your exact hardware model variant (TB-8704F, TB-8704X, or TB-8704V) before flashing. The TB-8704F Wi-Fi model lacks cellular modem hardware partitions present in LTE builds; cross-flashing LTE firmware onto a Wi-Fi unit (or vice versa) results in modem crashes, missing Wi-Fi/Bluetooth NVRAM parameters, or boot loops.

Compatibility & Bootloader Notes
QFIL firmware packages write directly to raw eMMC storage partitions via Qualcomm EDL 9008 mode and do not require an unlocked bootloader. Unlocking the bootloader is only required if flashing raw unencrypted images manually via Fastboot.

Frequently Asked Questions
Check the label on the lower back of the tablet casing or go to Settings > About Tablet > Model. TB-8704F is the Wi-Fi-only version, TB-8704X is the global LTE model with a SIM slot, and TB-8704V is the carrier build for Verizon/US Cellular.
Power off the tablet completely. Press and hold both Volume Up and Volume Down buttons at the same time, then connect the tablet to your PC using a USB cable. The screen will remain black, and Windows Device Manager will show "Qualcomm HS-USB QDLoader 9008" under Ports (COM & LPT).
No — bootloader state doesn't factor into that choice at all. Flat Build packages (individual partition images plus rawprogram0.xml) are the right pick for a standard full restore; Service/SVC packages are factory diagnostic bundles meant for service-center workflows, not typical end-user flashing. Grab a Flat Build package unless you specifically need the SVC tooling.
Flashing LTE firmware onto a Wi-Fi-only unit causes modem crashes, invalid Wi-Fi/Bluetooth MAC addresses, or boot loops due to missing cellular baseband hardware.
