[Solved] BU40N 1.04 Downgrade fail

#1 Post by Thommy » Wed Aug 16, 2023 7:42 pm

Best Regards @all Supporters

Since 3 Days I tried to Downgrade my BU40N with SDFtool Flasher (v1.3.5) and also with the modified LG Flash Tool but always failing.
(DE_LG BU40N_1.00.bin, HL-DT-ST-BD-RE_BU40N-1.02-NM01201-211711301218.bin, DE_LG_BU40N_1.03_MK.bin)

Im also confused I get 6 Binarys when Dumping my Original Firmware

Please give me a kick in the Right Direction :-)
