Hi,
Recently annoyed by the poor performance of the WiFi adapter of my Lenovo Y50-70 (20378), I decided to buy a new one (Intel AC 7265 NO VPRO).
I was surprised to discover the whitelist system of Lenovo and now I am stucked either with a poor connection or no connection at all.
Reading all this topics, I am quite confused on how to get rid off this whitelist.
As far as I know, I need to use BACKUP_Tools12.exe to get a result archive and then upload it.
Here is the file: https://www.sendspace.com/file/rorrky
Can you help me (or someone else of course) with that ?

Do not hesitate to tell me if I am wrong and if I must do something else !
Thanks a lot !
Best Regards

Hi Bios Mods! 

New to the forums, and I would love to have the latest BIOS for my Lenovo Y50-70 WiFi whitelist removed, and advanced menu unlocked.


Manufacturer: Lenovo
Model: Y50-70
Bios revision: 9ECN43WW (V3.03)
Bios Type: UEFI
Official BIOS download link - http://pcsupport.lenovo.com/us/en/products/Laptops-and-netbooks/Lenovo-Y-Series-laptops/Y50-70-Notebook-Lenovo/downloads/DS100998

I would like to have my wifi card upgraded from the stock Qualcomm Atheros AR956x to an Intel 7260AC.


This is my BIOS created using the Universal BIOS Backup ToolKit 2.0: http://rgho.st/private/6QXZWStQj/0099496...faca14150d

In addition, it would be very much appreciated if anyone could guide me through the process of applying the modified BIOS to my machine thereafter. From what I understand, I would have to downgrade my BIOS to v1.13 before applying the mod. Is that true?

Thanks so much!

Hello... i was middling with the bios and by mistake it seems that i set for PCIE video on the advance settings... now i cant get the motherboard to show anything, i tried the Banox method without any luck.

Now i want to try the Nathanial292 method and already made the usb msdos 6.22 bootdisk but i dont know where to get a standard rom (since the one i got from here is already deleted) and the utilies to flash it from msdos.

Thanks for any help. Ramiro

RE: unlock advanced menu lenovo y50-70
Hai BD Master,.. Hai everyone , whatsup ,,
been a while since i dropped by here,,

just wanna share this info on how to recover from soft brick Y50 , caused by changing Offset voltage in Unlocked BIOS.
This was tested n confirmed by "Jarn06T" from NBR, at least I got this usefull info from him, n this method referred from those guys on AW forums ,
kudos to all of 'em.

Basically need to remove back cover , 12 screws, disconnect Battery , and CMOS connector. unplug all ram modules.
then do Power Flee by pressing power button 20 secs or so, ( this might not be necessary ).

Then connect AC , power on, it will bootloop cos no ram installed.
- in one of the shutdown in-between bootloop , quickly connect CMOS battery connector back in its place..
- let it reboot, and it will shutdown again with still no ram Installed.
- after another shutdown ( still in-between bootloop ) quickly connect/insert 1 ram modules to its placed.
- then after next reboot, it shud back to life to enter setup MODE.
- then u cud load default settings and restart or shutdown to connect battery & another ram modules, if you had 2 slots installed.

shud there is any other method pls do share , or if this was a repost , please do apologize.

hopefully this cud help others experiencing soft brick after changing OFFSET VOLTAGE settings. NOTE : do not change Voltage
( undervolt ) inside BIOS. ony do in WIndows environtment.
:cheers:

rgds,

Posted for all lenovo Recovery Bios Users !

I used andys tool to get my bios version name (ZIVY2.BI)

http://forums.mydigitallife.info/threads...EFI-BIOSes

I know thats for Pheonix Bios'es but it was worth a shot...

Then got the original bios from Lenovos' website and renamed it to ZIVY2.BI.

I then placed that on a FAT formatted usb; keep in mind I also shoved every single possible filename :

ZIVY2.wph
ZIVY2.bin
ZIVY2.ROM
ZIVY2.FD
ZIVY2.BI
WinZIVY2X64.wph
WinZIVY2X64.fd
WinZIVY2X64.rom {These ones are what the bios file from Lenovo was originally called}
WinZIVY2X64.bin
WinZIVY2X64.bi

I ran the crisis mode(BATTERY OUT/AC OFF, hold fn+B OR fn+R then plug in AC then press Power) and the laptop bleeped
ALOT. 2 minutes later It was booting into WINDOWS!!!

I had to look around the internet for days but it was worth it if this was the result!

I hope you can tell all your lenovo users to try out this method.

I have got so far a long list of users with this issues and i cannot find any Lenovo Recovery Bios woking ! Good luck.

I hope these reports could be usefull to all users need help to make a Recovery Bios !

I fixed it!! here is how and maybe you wish to share that.
well i did played with the display settings so the laptop was not showing anything.
But that doesn't mean it was nto actually booting at least was trying but was propably geting a bsod, since the display was "disabled".
I tried the HDMI hours ago maybe i would get a tv out but nop.
after waiting 2 hours for the bios t clear as you said it doesn't because its in ROM that keep power for hours,
this is what i did.
- Download your new modified bios,
- Copy It in a msdos bootable USB Stick
- Also in the USB create the autoexec.bat and edit it inside to call the flash.bat automatically the next time the USB boots
- Open laptop and disconected the HD or SSD, so make sure the Bios will boot only from USB
- Plug the USB and power on the laptop WITH all batteries Connected! (because it check for battery state while flashing!)
- Leave the laptop to power on, and notice that the USB is trying indeed LED flashing, showing some sort of activity,
- Remember now that your flash update ask 1-2 times "are you sure" "press any key to continue flashing" so simply press 2-3 times the "Enter" key.
- USB start to flash even more now showing that the Bios was indeed flashing!
- Wait exactly 1 min, it doesnt take longer and to make sure it finished, then pressed 1-2 time more Enter key, until none activity on the USB flash led will be.
- Then the flash is over and needs a restart, lets make sure that its indeed over by forcing a command on the msdos to show some short off activity,
- Try to type "dir", and look flash led activity, (everytime type DIR blinded and Enter key, then the USB has to blinking, which means Bios Flash is over !
- Now Laptop is waiting for a restart!
- Press the POWER button 3sec to shutdown and then press again It switch on and boot !
- BOOM the screen has to came to life and You will have your bios installed and recovered.
- Turn Laptop off, connect HD or SSD, and then power up to setup bios !!!

Hi,

Just found out I can't use the 17265 wireless card in my Lenovo Y50-70 9ECN43WW(V3.03) because of the whitelist checkup.
Can you remove it ? Here are the results from the tool: https://www.sendspace.com/file/s8jin9

Thanks
