Lenovo Helix (Type 3xxx) BIOS PROBLEM + DUMP

[alip82]

A few days ago, i updated the bios of my laptop lenovo helix (type 3701) from windows. After successfully installation i couldn't get in to the bios and it was just black cursor blinking screen. Except that everything was ok. Later i decided to downgrade to the older version bios to get rid of BS. This time after bios install preperation, pc rebooted, screen was black for 15-20 min and fan was full throttle. I know I shouldn't interrupt the process, but somethings was wrong and i shut it down after 20min. I corupted the bios i guess. After connect the battery, when i push the power button fan rotates for 1 sec and stops. Then Power button reacts to nothing.

So, i really need your advices. I cut down the bios update process. Do i need to full dump from my bios chips for like serial number, uuid etc. What is my best solution. Or use only my friend exact same model full bios dump with no edit. If you guide me to righ direction, i would really grateful.

-Helix (Type 3xxx) Laptop (ThinkPad) - Type 3701-

I have ordered SOP8 clip and CH341A. Package arrived today.

My dump: (MX25L3206E.Bin,MX25L6406E.bin - I dont know which one is ec or bios)

before everything I think my bios was 1.35(GFET56WW) 1.24(GFHT47WW) - gfuj20us.exe

I tried to update 1.44(GFET65WW) 1.25(GFHT48WW) gfuj28us.exe then downgrade

I hope i could go back to 1.35 again.Thank you very much.

Doesn't work. This time there is no fan also.
When i write the peste's bin files write-verify it was ok. But when i tried to write your files software gave me "chip main memory with the contents are in disagreement" error. Then i searched the forum and learned "erase->blank->write-verify" method. Finally write and verify went normally. Am i have to erase before write always? Thanks.

I have a couple of questions:

1- Which chip is Main Bios and which chip is EC Bios? (MX25L3206E-MX25L6406E)
2- Which chip has the unique info like serial number, uuid etc? So i hope can transfer.
3- I can see inside of the MX25L3206E chip with UEFITool but i can't see the MX25L6406E chip. Is it normal?
4- Which tutorials i need to read for get unique info from chip dump? I guess there will be a lot hex edit.

Thank you.
