I think you forgot to plug in the BIOS battery.

the ec you sent is good. the bios password is also in main you need to send here the main bios.
and serial number.

There it is

[Vesko356]

Did you read my previous comment about the serial number?!

[highping0r]

Sorry but the sticker is hard to read. Here is a picture for proof. I hope that´s fine?

EDIT: Sorry but there is nothing on the outside or anywhere with the serial number
EDIT2: Got it 5CG0248HCN

[Vesko356]

This is not the laptop serial number. It's printed on the outside of the bottom cover!

It starts with 5CG
you can also search 5CG in unicode string in EC using hex editor.
if theres no SN we could not help you.

Read the chip with the main bios again, use verification. Posted dump is corrupted,

[highping0r]

I did verify that i read it properly 3 times. Chip looks like someone was there already. Should i just use a Clean BIOS then?

[Vesko356]

Of course not. Once the laptop is on and running, obviously the bios is fine (even with a password), you just need to read the chip properly, besides if you can't read it correctly, you won't be able to program it either.

[highping0r]

Ok, first time using one of those clips. i put it on and read the chips 3 times and always same result. I guess i have to desolder like i was doing before and post the dump again.

[Vesko356]

That would be the best approach. Using such gadgets almost always means a bad result.
Also, it is necessary and very important to have a good and verified bios backup before doing any other experiments.
You should read the chip at least twice (even better three times) and compare the contents between the dumps.

[highping0r]

Yeah sucks to desolder especially in those tight ereas but it gives the best results. I always do at least 2 backups and compare them, no worries.

[highping0r]

Next try. read it 3 times and verified that they are all the same, Please check
