Crucial Warning: Always confirm your exact tablet model number (TB-8704F, TB-8704X, or TB-8704V) before initiating a flash. The Wi-Fi model lacks cellular baseband hardware, and cross-flashing cellular firmware onto a Wi-Fi unit causes NVRAM corruptions, invalid Wi-Fi/Bluetooth addresses, or boot loops.

Frequently Asked Questions
No — every TB-8704 variant flashes the same way, through QFIL over EDL 9008 mode. The variant only determines which package to download, not which tool or procedure to use. Confirm which one you have via Settings > About Tablet > Model Number, then grab the matching archive from AndroidFirmwareFile (linked above) before starting.
EDL/QFIL is the only supported stock-recovery method for this tablet — it doesn't ship a fastboot-flashable factory image, so there's no alternate method to weigh. If you're used to fastboot on other Android devices, expect a genuinely different procedure here, not just different commands.
Stick with QFIL/EDL regardless of bootloader state — this tablet has no supported fastboot factory-image flashing path, so an unlocked bootloader doesn't open up an alternate method. It only matters if you're planning to go beyond stock firmware (custom recovery or ROM), which is outside the scope of a stock restore.
