Hi to all and mainly to anyone having to cope with Lenovo's BIOS update utility and ending up with a bricked laptop.
I'm posting because I got BIOS restored and happily my G550 is back to normal (back from the death). Since it's a cruel time to cope with, especially due to the installed software worth much more than the lappy in dollars and specially time, I'll tell my successful procedure just in case it helps anyone. More so, reading how plenty of proposed methods there are in the web about phoenix BIOS recovery which can finally get you on your knees after hours of trying.
My model is 2958 with a SN that won't pull any success in LENOVO's support search tool :-o. There are no doubts about what BIOS version it is, since there's just the 2.53 (Vista - W7 with 32 bit installer or the other one for 64 bit).
I rebooted before bios update as instructions demanded. My BIOS update got stuck in block 14 of 38 and as the others posters, I was doing it from a W7 pro 64 bit OS. As soon as it got stuck I knew LENOVO had bricked it. I even kissed it goodbye when pulling off the battery. Anger was high after all the trouble I got with LENOVO in the past to get my faulty screen repaired and replaced with another with several dead red pixels.
My laptop has NEVER hung or rebooted by itself, so I knew 99% it wasn't my fault, but when reading the forums and viewing many others with the same installer and SO and a bricked G550 it got up to a 100%.
I started to read all the lousy answers from admins in LENOVO forums and couldn’t believe it. So with little hope I started to search. Some had had success so I started to try. Details (for what I read that didn't work for me)
Never found CMOS battery in order to get it reset. So (in my case) no need for that.
Burnt a CD with bios file and wouldn't fix it, alone or with usb stick, even if it seems as it is reading.
Tried Phoenix recovery.rar (the one with HP USB Disk Storage Format Tool.exe and other files). Didn't work.
Tried CRISDISK.zip (the one with wincris.exe version 184.108.40.206, version viewable by putting your cursor over the file or in file properties-version). Didn't work.
Tried CRISDISK.zip (the one with wincris.exe version 220.127.116.11). Didn't work.
Tried Phoenix CRISIS DISK.zip. This one came with PHLASH16 v18.104.22.168 WHICH IS NEEDED FOR LATEST PHOENIX BIOS. Also with wincris.exe version 22.214.171.124.
Followed instructions in the zip. I was trying everything, so first tried compressed (makes sense for usb floppy) and didn't work. Then tried without compression and I T W O R K E D. I got it from here:
Usb port used: the one in the right. Battery was not plugged.
Procedure and laptop behavior:
Cut or unplug mains, push Fn and b keys, then power on mains and push power on button (keeping Fn and b pressed until it fist beeps). It will read usb then it would beep once; stop a few seconds, the start beeping first with a sequence of much over 5 beeps (which is indicated as error message somewhere). Then it would stop and make short sequences until it rebooted and came back to life. Took about 5 minutes.
Take into account that it acted much as with the other methods: sometimes (depending on which of the 8 usb sticks I was trying) it started with this beeping, but would never reboot nor fix anything. That may signal the usb is being read, but probably BIOS wasn't being properly flashed. Just a guess about how to know which sticks work. By the way:
The usb used was a crappy cheap 2 gig one. Formatted in FAT then passed through the tool. YOU NEED TO PLACE THE RIGHT BIOS IN THE Phoenix CRISIS DISK FOLDER. It will stick it in the usb, thought I'm not 100% sure if I afterwards copied again the BIOS file.
Being suspicious of the bios included in the 64 bit killer BIOS updater, I USED THE ONE INCLUDED IN THE 32 BIT APP.
I think nothing is left. It was: I prepared usb stick in a windows xp machine.
Well, LENOVO, thanks for putting up this forum so your own (in my case just once) customers can try to solve the problems your own incompetence generate.
AND NO IT IS NOT SAFE TO UPDATE BIOS (the file is still there waiting for geeky BIOS updaters....), so unless it is broken DON'T DO IT!.

OS: Windows 7
I tried updating my BIOS after installation of windows 7 operating system. However, the BIOS update process stopped responding and now I am facing the problem of bad BIOS. After plugging AC power and power on, the screen is blank. I have searched on internet about the problem and I came to know that CRISIS disk can recover BIOS using 'wincris' tool. I tried to use this utility but I don't exactly know how to use it and it's not working for me. I would like to know about the solution to my problem. Is there any official guide for BIOS recovery?

I haveexactly the same problem. I tried to update bios (Lenovo G550) - and now the computer wont start.
Black screen - and no responce at all ...
How do I reset the BIOS - the computer dont have any warranty left - so i want to be able to do the reset myselves.
I have tried to move the battery and pressing start (to "unload" the machine) - but with no succes.
I cant find the cmos battery - to try to reset the bios if i removed it for some minutes.
1.How can I reset the BIOS ?
2. Where is the cmos battery ?

This post has been edited by Mod erasing my mention of a previous post from me with detailed instructions about how to solve this problem ¿¿???. Is this post visible to you?
It's long but it's how I solved your exactly same issue. Even linked the file that worked for me.

there're ways to recovery bios but when you have valid warranty, it'd be easy to ship it back to service.
- but it seems that many people (like myselves) dont have warranty left on the broken down computers - so im looking forward to a solution, which i hope that you would "release" for us here.
It cant be true, that we have a computer, with secrets, so we cant repair them ourselves, when the warranty runs out.

4-RESURRECT YOUR LAPTOP:
