Unlock Lenovo G770
#1
Hey,

I am pretty sure that this has been requested before (and I have found the older version modded and siccessfully managed to install it using a rom from this site and a tutorial also from (or linking to a topic on) this forum), but I would jave really liked a mod that unlocks the bios options for this version (I would have liked to use this since it's the latest version by Lenovo.. Also, after installing the older modded bios, in the bios information it shows that the bios version is the older one, while the "EC Verdion" seems to correspond to the newer bios ( which I had installed before the modded one).. so I don't know whether this can cause problems or not).

So, here is the BIOS I'd like unlocked (attached).  

Thank you very very much!

Please, can someone help me?

Please delete my other topic, I'll repost here trying to be more specific. I apologize if I am being insistent, but I thought reposting and trying to be more conformant to the topic rules (like the [REQUEST] in the title) would increase my chances of receiving help.

So, please help me by unlocking the bios I've attached to this topic. I've also attached a picture of my current BIOS (it seems like the BIOS version and EC version are not the same.. I don't really know what "EC" is. This was probably because after I updated using the attached bios, I installed an unlocked older bios from this website (which seemed to work, but I'd really like the latest version)). I'd like the attached version modded because it's the latest provided by Lenovo on their website and it's a BIOS I know for sure it's for the G770.

My laptop is Lenovo G770 20089.

Thank you very much.

Wait.. actually, does someone know if my laptop supports UEFI? That's what I wanted the bios unlock for Sad

@Moderators: can I not delete my own posts?


I just to add a few more things (maybe I should have edited instead, but I hope it's more visibile like this):

- I've now added a picture of the actual BIOS in my OP (stupid me.. I actually posted a picture after installing that older BIOS)
- I'd like the BIOS unlocked in order to try and install a Hackintosh (and I do not have any UEFI option in my bios (I know it can be done without UEFI, but I wanted to try).. still, maybe unlocking other options as well can't be bad for a Hackintosh.. who knows what else I may have to modify in there)
EDIT: I saw there's also a Hackintosh section on the forum.. should I've posted there instead?

Thank you! Smile

Please, why does no one answer? At least please tell me why. I have found that some mods for my BIOS version were actually done on this very website, but the links no longer work. Can't no one mod this BIOS? (3.10 for Lenovo G770) ..
