Crucial Warning: The five builds below are a starting point, not the full list — this family has 20 known files in total, several split across hardware-revision batches (HW21, HW23, HW25, HW43, HW62, HW20) not shown here. If a device doesn't boot cleanly after following the walkthrough with one of these builds, check the complete archive linked below rather than assuming the download itself was bad — on this particular family, a hardware-revision or chipset mismatch is a more likely culprit than a corrupt file.

A later TB-7304F build in the full archive uses a different chipset (MT8167) than this one (MT6737M) — see the complete archive linked above before assuming the two are interchangeable.
↓ DownloadCompatibility & Bootloader Notes
SP Flash Tool writes the selected partitions directly through the MediaTek Preloader/BROM interface; there is no separate fastboot-style bootloader lock/unlock step on this chipset family the way there is on Qualcomm or Motorola devices.
Preparation checklist for Lenovo Tab4 7 & Tab4 7 Essential (TB-7304F, TB-7304I, TB-7304X, TB-7504F, TB-7504X)
- Confirm the exact model number (TB-7304F/I/X or TB-7504F/X) from Settings > About tablet.
- Where possible, confirm the actual chipset via SP Flash Tool's own connection log rather than assuming it from the model number.
- Install the MediaTek USB VCOM drivers and a build of SP Flash Tool compatible with Android 7.0-era MediaTek targets.
- Back up accessible user data before choosing a full Firmware Upgrade (Format+Download) flash.

SP Flash Tool (MediaTek Download Mode)
SP Flash Tool works the same way across thousands of devices from many brands, so the full walkthrough lives on FlashGuideHub. What is specific to Lenovo Tab4 7 & Tab4 7 Essential (TB-7304F, TB-7304I, TB-7304X, TB-7504F, TB-7504X) is below.
- This family needs the exact scatter file for your model number and hardware/build tag — HW21, HW23, HW25, HW43, HW62, and HW20 each denote a different hardware-revision batch, and one TB-7304F build in the full archive uses a different chipset (MT8167) than the rest of this family (MT6737M).
- Confirm your tablet's actual chipset in SP Flash Tool's own connection log before flashing — two units printed with the same TB-7304F model number are confirmed in this archive to use different chipsets, and a mismatched scatter file will fail DRAM/preloader validation rather than just not booting cleanly.
- See FlashGuideHub's SP Flash Tool guide for the full connection, scatter-loading, and download-mode walkthrough.
Frequently Asked Questions
TB-7304F is Wi-Fi only, TB-7304I adds 3G, and TB-7304X adds LTE — all three are the same Tab4 7 Essential hardware otherwise. TB-7504F and TB-7504X are the separate, larger Tab4 7 line, in Wi-Fi-only and LTE variants.
No. TB-7304 and TB-7504 are different physical tablets with different hardware, even though several TB-7304/TB-7504 builds in the archive share the MT6737M chipset. Always match the exact model number printed on your device.
Connect the tablet to SP Flash Tool in download mode — the tool reports the connected chipset in its own log before you load a scatter file. This matters because this exact model number is confirmed to have shipped under two different chipsets (MT6737M and MT8167).
