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 ,
n it will shutdown again cos 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.

I decided to do >>> BIOS Recovery :
................................
Insyde BIOS Recovery
1.) Obtain the correct BIOS file for your system. The file extension will usually be one of the following: “.fd” “.rom” “.bin” “.wph”
2.) Please see paragraph 3 to determine what you should rename the BIOS file to.
...................................................................................

I haven't find any Lenovo Laptop with working Recovery Bios !!!
I saw hundred Lenovo Laptops and all with same issue !
UEFI Bios needs a special .efi tool which is not public and I
haven't so only SPI Programmer can do the job !

How to Recover a bad or brick bios in lenovo laptops:

1.Download Phoenix Wincrisis then Click on the WINCRIS.exe and choose CREATE MINIDOS CRISIS DISK and press START to make: USB Flopy or usb flash memory.
When creating the boot Floppy or usb memory, select from Folder Options to view the hiden and system files and delete or rename the file config.sys if present.
2. Download your Bios file from lenovo.com if u dont have it, Rename your BIOS file to bios.wph and copy it to your: USB Floppy/usb memory.
3.Plug USB Floppy/usb memory into laptop and shotdown.
4. Hold down Fn+R keys and while holding press the power button.
5. Now you should hear the flopy drive working or usb blinking, hold the keys for a while.
6. Leave the computer for few min. and if the computer does not restart it self turn the power down.
7. if everything went OK the computer shold start normally.

Note: This procedure is for Phoenix BIOS`es only and this metod works only for lenovo.
VERY IMPORTANT NOTICE ABOUTE RECOVERY LENOVO LAPTOPS: Do not take off your battery before flashing unlike the others brand that you should take off battery!! It seems that before flashing, it verify AC/DC connection and battery level. If one of them is not ok, then reflash is stopped.
