LANIX NEURON FLEX 12C4-C20 BIOS REQUEST

[empm_mx]

I need the bios for this Lanix, bios setup had password, I desoldered the SPI chip (25LQ64CVIS) it read once (I used RT809F) but the backup saved was corrupt, I tried to read it again but it fail, I suppose the chip is dead, I´ve been searching over internet but couldn´t find a matching bios for this laptop model or motherboard.

MODEL: LANIX NEURON FLEX 12C4-C20
MOTHERBOARD: In-SG133H_VF1
SN: 2882301749
SPECS: Intel Celeron J4115, 4GB RAM, 64GB EMMC

Thanks in advance.

The 25LQ64CVIS is 1.8V ?

Sorry, somehow I mixed the SPI chip model, it is actually 25LB64CVIG which is 1.8V, RT809F doesn´t have that model but has GD25LQ64C_1.8V

Choose GD25LQ64C manually then , and if there is a verify option turn that off. Post the new backup

I did disabled auto-verification, read it two times with two different options: GD25LQ64C_1.8V and GD25LQ64C_1.8V(8K BIT OTP) it´s still corrupted, I didn´t tried before but I soldered it back to the motherboard, laptop turn on but it has no image, I assume the chip is dead.

I can´t upload bin files, but the file in hex editor looks like the image, that´s why the zip is so small

[SMDFlea]

Its not a One Time Programmable chip (8K BIT OTP) , so choosing that will make no difference,other than adding extra code to the end of the file. Anyway, do you have another programmer you can try, a CH341A or something

[empm_mx]

no I don´t have another programmer right now, but I´ve found a different motherboard with the same SPI chip, it was read with no errors.

Ok, the chip is truly dead then .

I managed to get it read after scrapping the center and pressing with the hot iron set at 300°C while reading (otherwise it gave me reading errors), flashed another chip and the laptop is back alive but has password, I tried using the method for the Surface 3 (with the excel decryptor), tried with the amidecrypt (didn´t find the AMITSEDecrypt folder) , tried the XOR method for Panasonic, but I couln´t unlock it, can someone help me pls?

thanks for taking your time, but it is still asking for password.
