I am having problem with Lenovo Xiaoxin Pad Studio TB351FU. Can you help me fix it? I can pay you for your help. No problem. I have got this problem after I installed the firmware with Lenovo software. I have tried to flash many times with SP Flash tool but same result. Fastboot work apparently but I cannot unblock bootloader. ABD not working. If I format it with SP Flash I see the tablet on com port otherwise no EDL. Serial number changed. I don't know what to do it. Please Thanks
