Re: Lenovo Y50 BIOS Recovery/Reset method needed HELP!!

Hai Sir,

I have tried every methods I cud find on net. I hv succeded initiating the crisis recovery by removing back cover , dis engaged the battery and use Fn+R or B while plugging the AC plug, then press Power button. Fan Spin UP full RPM , keyboard backlit off , but seemed not to find the recovery bios name i put in USB.

I hv created dozens of file name combinations. from the latest extracted bios file .

I really dont know what else i was missing. I m gonna try to check loading the bios file using DVD drive not USB , some people say , only workin thru DVD drive.

ANy suggestions and informations would be very much appreciated.

regards,
FetZzo

Okey... been a while since nobody responded my issues.,,so heres the thing

A guy found how.to recover y50 fem soft brick ., this methods similar to those guys in AW forums did.

Basically u need to open back cover, unplug battery, cmos.connector and ram modules.,,

- do a power flee by holding power button 20 secs or so.
- then connect ac adapter while those above stay disconnected.
- then power on, the y50 gonna bootloop endlessly, ,
- in one of shutdown , connect the cmos connector, then
- in another shutdown, plug in 1 of ram modules. ,
Then y50 shud reboot entering setup mode / bios.
Load default n so on.,,

Re: Lenovo Y50 BIOS Recovery/Reset method needed HELP!!

Hey, I just recovered/reflashed my bios today. Everything works like a charm

I went through everything. I pulled the batteries, and held the power button. I cycled my power and put in ram sticks, I pulled my display and check if it worked on another laptop's LVDS connector, I Heat gunned my GPU. Literally everything.

Here are the steps:

 

1. Get a BIOS file.  Here is a link https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Y50-Bios-3-03-problem/td-p/2178818
The third post down has different versions. I used V1.14. The latest version from the lenovo website has no .ROM file, so I guess it's not an option.

2. Open the file with 7zip. You'll have to download it by googling, it's free. Open the downloaded BIOS file (Should be called "9ecn31ww" by right clicking, going down to 7-zip => Open Archive.
Extract the file named WINZIVY2X64.ROM to a folder of your choice. Perhaps the desktop.  The file will be 9 908 160 (bytes) in size. DO NOT FLASH A FILE THAT HAS A DIFFERENT FILE SIZE.

 

3. Part of the process requires your BIOS file to be correctly named in order for it to properly recover/flash. In this step we're going to rename the files to every possible combination of BIOS filenames.
Getting these names is a difficult proccess, that I honestly know nothing about.

Get Notepad++, it's also free. 
Open WINZIVY2X64.ROM with Notepad++(regular Notepad does not work for this part, believe me I tried,it will simply save the names as WINZIVY2X64.BIN.ROM, same as using just the windows rename feature)


Now select 'Save As' and save it as the following: (Repeat the process for each file name. You should be getting several files each with a different name as you save more copies in the folder where you initially placed WINZIVY2X64.ROM)

WINZIVY2X64.BI

WINZIVY2X64.BIN

WINZIVY2X64.FD

WINZIVY2X64.ROM

WINZIVY2X64.WPH

ZIVY2.BI

ZIVY2.BIN

ZIVY2.FD

ZIVY2.ROM

ZIVY2.WPH

 

(This last set seems unlikely to be the correct names to me, but I saw someone else claim they used it, and it was on my USB drive when it worked so who knows?)

ZAVY2.BI

ZAVY2.BIN

ZAVY2.FD

ZAVY2.ROM

ZAVY2.WPH

4. Take a USB flash drive, go to "My computer" Right click on the USB drive and select Format. Change the filesystem from NTFS to FAT32. Format the drive.
The flash drive does not need to be a 'bootable' flash drive. Leave it as is.


5. Copy all the files from step 3 to the flash drive.

 

6. Unplug your laptop from the AC adapter.
Disconnect the battery from the motherboard. 
With everything disconnected hold the power button for 20-30 seconds. This purges residual power from the board.
Disconnect the hard drive (This ensures that the USB flash drive is read first. I'm not sure if this is necessary, but it was the case when my flash worked)

7. Plug in your USB flash drive into any USB port.
8.HOLD Fn+B
9.While HOLDING Fn+B, plug in the AC adapter.
10. While still HOLDING Fn+B press the Power Button.

11. You should hear the fans turn on very loudly, no display, and no keyboard lights.
Let go of Fn+B after a few seconds
You should hear a rather loud series of beeps. This is the BIOS being flashed. Let it beep repeatedly as long as it needs to. When the process is done, the beeping will stop, and the laptop will turn itself off. It may also reboot.

If all went well, you're screen should now be working just fine. Put everything back together and help others out if they have the same problem. Feel free to ask me questions.

I also have to mention this part, because I firmly believe it was instrumental in my success:
While doing the process, I prayed like I never have before. And I mean prayed. To God. I've had it happen far too many times, where I've prayed and literally right then things started working, for me to think it's an accident. I feel like I'd be letting God down if I didn't bother letting others know that he helped. And I promised that if it worked, I would post my guide on the web. Not trying to convert anyone, or be weirdly religious, just doing what I think is right.

Re: Lenovo Y50 BIOS Recovery/Reset method needed HELP!!

I had the same problem. Make sure that you renamed the files with Notepad ++ 
Using Windows or just regular Notepad will simply rename the files to something like ZIVY2.BIN.ROM

Downlaod Notepad ++ for free and rename all your files.
Make sure that the USB drive you are using is formatted to FAT32. 
NO hard drive connected, and your main battery is disconnected.
Also make sure that the USB flash drive was formatted using the standard Windows explorer, and is not a bootable drive made by something like RUFUS
