Hi guys, I updated my bios by downgrading to v2.07 whitelist following the instructions in the initial post, then upgraded back to V3.05 stock bios and ran "EC.bat" on a dos usb stick that worked fine, then patched the V3.05 stock bios and it would not upgrade because Error 280: Failed to disable write protection for the BIOS space! so I tried flashing v2.07 again and that worked and then I flashed my modded V3.05 and that worked just fine, everything seemed to be working. then I installed windows 7 and went to install all the lenovo y510p drivers (not in any order) and I it had me reboot a few times, and now I am stuck with a black screen and no logo even ! I tried following this Edmar Hobby - Electronic: Lenovo Ideapad Y580 Insyde Bios Reset/Recovery but it did not seem to help :/ please anyone can help me? lenovo support is not very helpful at this point

thats because you gota downgrade to 2.07 first then run the EC.bat in dos mode to update EC part then after that you flash your moded 3.05 bios since if you downgrade to 2.07 then to stock 3.05 then EC it will throw an error since 3.05 has write protection on EC while 2.07 does not.

Update: also like svl7 said you all should keep copy of your original bios.bin that bios backup tool creates it is so you can flash your original bios back to laptop if you don't want the mod anymore

DOS, dude... not Windows.

yeah i figured it out xD well i got CE flashed into my laptop now next is to flash 3.05 thats modded

i see well i created a dos usb and moved EC files to it but when i run EC.bat it says it's not compatible for 64 bit of windows :/ so in what way am i supposto run that file?

Nvm apperently you had to boot into USB as DOS mode and then do EC.bat xD

Yeah, as stated in the READ ME file.

Thanks i will try this right away i already got a backup of my bios.bin also do i really need to downgrade to 2.07 first or can i do this straight onto my exisiting 3.05?

Nvm i saw you wrote it is recommended to downgrade to 2.07 first then flash moded 3.05

Sup dudes, here's the mod, please let me know if everything's fine.

Don't have much time at the moment, will be away for some days, gonna update the main post and instructions when I'm back.

So... Generally it works just as before, but I advise you to update to v2.07 (if you're not already on that version) before going to modded 3.05.

Then you basically follow the procedure as described in the first post, but you'll have to flash the EC separately. I recommend flashing it before going to modified BIOS 3.05. Just put the files in the EC folder on your DOS stick and execute the "EC.bat" (make sure you're on AC and not Battery only).

Then you can go ahead and flash the BIOS. After flashing the BIOS go to the setup and load the default settings.

I'll look into the ME Update when I'm back. If anyone could post a screenshot of Nvidia Inspector showing the OC stuff I'd appreciate that, just to make sure I didn't mess up.

Cheers!

Yay finally does this one unlock the menus right?

It's your battery voltage.

okay that explains it xD idk why program couldnt say that lol, since it doesent have any name above or next to box sayin what it is xD

well either that v staus is for cpu or so since when i checked tabs CPU:OCCT, CPU: LINKPACK, GPU: 3D, POWER SUPPLY all of them has same window with 12,25- 12,26 so i guess either it's cpu voltage or so instead.

while gpu-z gave 1.310V on VDDC

mine went to around 1.310V as max but it was around 1.100V first.

if i check another program under GPU: 3D it says 12,26V

if your talking about the VDDC then it's max around 1.100V

where in gpu-z can i see gt755 vbios version?

Nvm apperently mine has 80.07.A8.00.2E like you said svl7

well idk the version for the GT 755M :/ haven't updated it or anything, also are you able to provide a unlocked menus for bios version 3.05?

well my y510p has GT 755M on both gpus so could you fix for 755 as well and not only for 750M?

does anyone have a copy of bios version 1.07 or 1.09 or 1.10? since i would like to be able to flash moded bios version that unlocks every hidden menu untill svl7 manages to fix one for 3.05 :/

so any luck on getting menus unlocked for version 3.05?

also if you manage to fix this does it also unlock so MSI afterburner can adjust the fan speed or monitor fan speed to?

Hi i flashed down to 2.07 but noticed it was wrong version that i needed so i went back to 3.05 but now my EC is stuck at 2.07 instead of 3.05 :/ is there some way to get EC back to 3.05?

Okay for some reason my cmd.exe seems to be the problem... (I disabled the AV software, disabled UAC + registry).

So I decided to use powershell. Powershell was able to do the backup.bat with: "start backup.bat" so yay! I got a bios backup and went on to modifying it.

NOW. The problem is I can't flash it. I tried flashing with the script provided on the powershell, and it doesn't like it. And then I tried it with "start" and it doesn't get the -bios argument. Then I went to the cmd and I got the same damn Error 284: Fail to load driver (PCI Express) Tools need to run with administrator privilege account.

What the hell? What is wrong with my cmd???

that blue box is not CMD it's Windows Powershell you would need to find cmd.exe right click on it and run as administrator then cd to path where you got the bakcup.bat at and then type backup.bat and it will begin dl some stuff from flash memory or w.e BIOS is installed at, and once done you should find a bios.bin inside your folder where backup.bat is located at.

Ops could a moderator put this 2nd post with my first one? i forgot i already did a post reply so do this incase double post isnt allowed.

does anyone here know any modded bios v3.05? for y510p? if not i will have to wait for PM off svl7 with answer.

there is one AC card that works in y510p for those who does not wanna risk on flashing a moded bios into their laptop they will have to go to this link IBM Broadcom BCM94352HMB 802 11AC Dual Band 2x2 AC Bluetooth 4 0 867Mbps Card | eBay i ordered this one from china and got it yesterday and then i installed it into my y510p and it works great no issues at all it booted up fine and i installed boradcom wireless drivers and then wifi was enabled and that it's detecting 5GHz and 2.4GHz band since it's a dual band wifi

I'm so gonna try this Bios mod in my y510p also does it even unlock the FAN status for programs like HWMonitor Pro and to be able to see current RPM speed on gpu fan? and cpu fan?
