Bootloader Unlock
Bootloader unlock steps, token handling and verification notes for people working from Linux on the Lenovo Tab Plus TB351FU.
- Device-specific unlock token generation.
- Guidance around the required auth and flash assets.
- Fastboot checks after the unlock step is complete.
Lenovo Flash XML Helper
Utility for decrypting Lenovo firmware metadata and preparing a cleaner SP Flash Tool package for TB351FU restores, testing and device-side work.
- Decrypts Lenovo
.xfirmware metadata. - Checks the XML structure and referenced image files.
- Builds a flash-ready
sp_flash_tool_bundle/.
TB351FU AVB Kill
Standalone patcher for TB351FU AVB images. It modifies
vbmeta, vbmeta_system and
vbmeta_vendor so boot verification checks can be
disabled during bring-up, recovery work and custom
modification testing.
- Patches the three required AVB-related vbmeta images.
- Includes a simple fastboot install script for flashing.
- Useful when modified partitions trigger AVB verification failures.
Development Status
Recovery and ROM work are still in progress
Recovery and custom OS work are active. If you want to help with bring-up, testing, logs or development, contributions are welcome. Please do not spam for ETA.
Custom Recovery
Recovery work for the TB351FU is still not fully built. The current TWRP device tree is the working base, and help with bring-up, testing, logs and fixes is welcome if you want to contribute.
Recovery is still incomplete. If you can help with development or testing, contributions are welcome while bring-up continues.
Custom OS
Custom OS bring-up for the TB351FU is currently targeting LineageOS. The device, kernel and vendor trees are now public, while firmware packaging work is still being cleaned up for a safer release. Contributions are welcome while bring-up moves forward.
Current ROM target is LineageOS. The public trees below show the current bring-up base. Please contribute if you want to help, and do not spam for ETA.

About
Hi, I'm Pratik Gondane.
I am a computer engineer with a diploma in Computer Engineering, a B.E. in Computer Science and Engineering, and an M.Tech. in Computer Science and Engineering. Most of my work sits around Android internals, Linux systems and understanding devices at a lower level.
I build and share tools that make TB351FU development easier, from unlock workflows to firmware prep and ongoing bring-up work. This site exists to keep the useful links, tools and project status in one public place. If you need to reach me directly for something useful, mail me at hellopratik@proton.me .
