[REQUEST] Lenovo Ideapad 100-14IBD & 100-15IBD (E0CNxxWW) BIOS Unlock
#1
Hello, i had some problems trying to mod this BIOS. 
The laptop is a Lenovo Ideapad 100-15IBD with Intel Core i3 (Broadwell-U 9 series), 4gb RAM, Intel HD Graphics 5500 and nVidia 920M.
I have tried to install Hackintosh in this laptop, but i have problems with the DVMT Pre-Allocated memory. Default is 32mb, i need 96mb.
I tried to mod the EFI variables from the EFI shell but it did return me an error (something like "can't set variables 0x00000000000001").
I'm sure i didn't do anything wrong, so i thought that my bios could have variables locked.. Anyway it's not RSA signed (i think) because
Phoenix Tool doesn't say "Decrypted" and it can open my bios file.. i only need the DVMT changed to 96mb. Thanks in advance Smile
PS. BIOS version is E0CN23WW.
PPS. Original BIOS from Lenovo .exe and my backup with fpt doesn't match in size.. if i look at the bioses they are identical, but one is 9mb and the other is 6mb. I don't know why.
PPPS. I also wanted to know if i could in someway recover from a bad bios flash Smile

Original BIOS extracted from the .exe on Lenovo site: Link (Mediafire)
Backup BIOS done with FPT v10.0: Link (Mediafire)

Hello!
All bioses for newest laptops can be modded using SPI Programmer+Pomona SOIC 8 Clip only.
If you have/buy these tools so i can help you.
Regards!

Please,do not post requests me in PM.Bios modding is very dangerous work.If i provide you confirmed modded bios, please donate for my dangerous work https://goo.gl/98BgtO.Thank you!

Hello! Thanks, but i am a little scared using a SPI Programmer and right now i don't have one and i don't know which one to use.. Maybe later i will think to use one.. Thanks anyway for the help. Are you sure i don't have any other chances to mod bios via software? Sorry for wasting Your time, regards!

Hello, I was wondering if there would be any performance gain and would request if so a bios mod. I will be running windows and multiple Linux distros on this laptop. I would like to get graphics or CPU performance gains. The default bios is https://download.lenovo.com/consumer/mob...cn61ww.exe

Thanks,
John Cool

Hello everyone.

Could anybody please unlock the hidden options / menus for this BIOS (E0CN63WW)?

I saw that there are many hidden options available such as an Advanced tab and even overclocking sections etc.

If any additional files or information is needed please let me know.

Thanks! Smile

hi, am really interested in the work that you have done i have the same device that the OP has and i can buy a SPI programmer but i just want to know what where you able to unlock exactly are we talking like removing power limits, BCLK ratios and stuff or just some basics like more reserved memory i have already heavily modded the cooling system of my laptop(it's basically not a laptop anymore but temps never go above 45 under full load)so it can take a power limit unlock (temps wise at least) (am a student so i can't really spend money that freely that's why am asking for what could be done. because if it's worth it (power limit unlock) am very willing to spend the time and money required as i can't really get anything done on this machine in it's current state)
