Re: Lenovo IdeaPad 3 15ADA05

I always do 1000 - 2FFF ,LDBG 0-FFF is written at first boot. @hoaca always includes 0-FFF ,so i don`t see it making any difference either way.
.

Since the OP refereed to the dump in post #1 which is not virgin one downloaded from Lenovo, but some dump taken from a working machine it's best the whole area to be replaced from the original file.

Hello,
Motherboard GS450&GS550&GS750 NM-C821 REV 1.0
Attached original bin file.
I don't know the serial number of the laptop but the bios posted in the first post of this thread has worked but I would like to copy the DMI region from my original file.
Can somebody help me? or tell me what the dmi region is since I have read two different ones in this thread (from 1000 to 2FFF) or from 0h to 3000h.

Thanks in avance

Re: Lenovo IdeaPad 3 15ADA05

try post #29..

I already tried that yesterday but with my own DMI DATA. but when you suggested that file i tried without editing the DMI DATA and it push through with
pre-installed OS. so, i tried editing again with my own DMI DATA and it works also. maybe the first time i edited the DMI DATA area i copied the wrong addresses. thank very much for your help...

Re: Lenovo IdeaPad 3 15ADA05

Hi, I have the exact same problem. I have the original faulty bios, but I don't have the data sticker. I know it's 15ADA05. Can anyone help with a working bios? Thanks

Re: Lenovo IdeaPad 3 15ADA05

I have tried a few of the BIN files posted here (#1, #29, #38), and none of them are working for me. It still gives me the same problem. Black screen, nothing happens, tried many key combinations, USB booting, etc.

Unfortunately I do not know the serial number (the sticker on the case seems to have been taken off), but I have attached my corrupted BIN file I read from the chip. I don't really mind if it's different. If anyone could help me with a working BIN or what other issue my laptop has, I would be ever so greatful.

Re: Lenovo IdeaPad 3 15ADA05

Hi, could You help me with my bad bin file pat_ban_W25Q64FW? I uploaded the NM-C821 bios .BIN file and on it the board turns on, but it does not detect the disk, no serial number, etc.

You can add the DMI yourself. See the attached README text file.If you still can`t see the disk try the virgin bios at post #29
