Crucial Warning: Match the exact model number (701LV or 702LV) before flashing ? despite sharing the X704 chipset family with the global Lenovo Tab 4 10 Plus (TB-X704F/L/A/V/Y), these two models are NOT firmware-interchangeable with the global TB-X704 line or with each other. The waterproof housing, TV-tuner partition, and carrier lock differ between 701LV (SoftBank) and 702LV (Y!mobile).

Expand preparation checklist for Lenovo Tab 4 10 Plus TD-LTE JP (701LV / 702LV)
- Confirm the exact model number (701LV vs 702LV) from the device label or Settings > About tablet.
- Install the Qualcomm QDLoader HS-USB driver and QFIL before attempting a flash.
- Use a reliable USB cable ? a full QDL write takes several minutes and moves the full system image.
- Back up any accessible user data; a full QDL flash overwrites the affected partitions.
- Do not attempt to flash global TB-X704 firmware onto a 701LV/702LV unit or vice versa.
Compatibility & Bootloader Notes
These are full QDL/EDL packages flashed via QFIL over Qualcomm's Firehose protocol, not a fastboot/mfastboot package ? standard Android fastboot cannot write these images. Both models are carrier-locked (701LV to SoftBank, 702LV to Y!mobile); reflashing this stock firmware restores the system/boot/radio partitions but does not remove the network/SIM lock.
