How about Lenovo S920 with CMIIT ID 2013CP5257. I bricked it and fail to retrieve it even using the method posted. But pc still detect it when i connect it without battery. Detected as MediaTek USB Port. But if I try to flash only the preloader, it give error. BROM ERROR:S_FT_ENABLE_DRAM_FAIL(4032). I try to format it and still give the same error. If I try to flash the whole rom, the same error pop up and if I try to flash without the preloader, still the same error given. I already try 4 firmware. This is the firmware that I try..
At least please help mewith backup preloader and scatter file.
