Hello guys, this is my first post here.

I think ive just messed up my notebook by trying to update my bios. :(

Do you guys know if there is any way to find the original BIOS (201), so i can burn into my mobo? :o

I can RMA it, but im in Brazil, so i dont want to waste that much time (and money) since i really know what im doing. :cool:

If your laptop no longer functions after a failed BIOS attempt (i.e. you are now unable to access the BIOS), it will not be possible to reflash the BIOS. Recovery requires a special tool to rewrite it, and requires an RMA to ASUS.

Thanx for the quick response "dstrakele"!

There is mobo specialists in my state that can reburn the bios in the chip with that tool. Thats why i wanted to know if exists any way to find the original 201 BIOS to burn in. :)

Any advice?

I see only 202 and 203 here: http://support.asus.com/Download.aspx?SLanguage=en&m=G74Sx&p=3&s=336 You need to enter your OS version.

Just curious - Why wouldn't you want to just overwrite the BIOS chip with 203?

Hm, nice question! :p

I think i can ask this to the specialists i told you. They only told me that they need the original bios software, and not the upgrade ones. Anything new ill let you know...

Thanx again!

Interesting... I was under the impression that the tool capable of rewriting the BIOS on the chip could rewrite any file version. Never seen or used one, so that was only my assumption.

Hum... i hope someone can help me now! :D

They told me that needs the ".rom" file, 32mbits, instead of the ".202/.203" file, 2mbits, that ASUS provide in their download section.

I think we getting somewhere. Any advice? :D

Any BIOS file can be renamed with the ROM extension.....this is commonly done with the files when used in emergency flashing procedures. Maybe that's all they meant?

You can get BIOS 201 from your cd driver. Open Root folder. See G74Sx.BIN file. That's BIOS 201. You just can check the BIOS version with WinFLash...(If Possible).

Thanks, Brody! ;)

Nice to know, ill tell them this tommorow!

The 32 or 2mbits, part... makes difference? :confused:

This is not what I want, but if they can not do it anyway, you guys would rely on things like this:

http://www.ebay.com/itm/BIOS-CHIP-ASUS-K42JB-K42JK-K42JR-N45SF-N55SF-N75SF-G53SX-G50G-G74SX-/170715639663

And In the latter case (past it), there is somewhere I can find a new motherboard G74Sx? :(

The download worked fine, Brody. Thank you very much!

Thank you all for the "helpinness" and for being so kind! It is increasingly scarce in today's world and it is, imo, because of people like you that the world is still livable!

Ill keep u guys updated!

Thanks again!

Unfortunately, Brody is still on an extended vacation..
I still have the original G74 driver CD. Send me a PM of your email address
or give me a link of a file sharing site you trust, so I can give you that G74Sx.BIN file.

On a side note, the OP didn't give a definitive conclusion of this thread if indeed
the G74Sx.BIN file in the "Root" folder resolved the issue.. so it makes me wonder
whether it was really helpful or not.

Hey guys, sorry to dig up an old thread.

Have exactly the same problem, bought a 2nd hand g74sx from ebay did a 203 bios update and bricked it, tried a 203 bios swap and that didnt work, so now looking for original 201 bios to reflash it. If anyone has it would you be able to email it to me please?

really dont want to spend $300+ on a new mobo.

thanks.

Hi Clint82, sorry to hear that bios flash didn't go better.

1. Anyway, if you were able to replace the bios chip, wondering why that didn't solve the problem and worried there were problems to resolder the bios chip to the motherboard or it wasn't the right bios chip, but there could be other reasons it didn't work.

Although this doesn't always work, if you are using the original ASUS Windows image with the bios *.BIN file in the root directory (if you check your hard drive in windows with a different system, you want to show hidden files, etc.), you can try holding the CTRL and HOME keys at the same time while pressing the power button to start the bios crisis recovery.
If you have a copy of the G74SX driver disk, there should be a copy of the G74Sx.BIN file in the root directory if you need it, or send me a PM at cl-Albert with your email address and I'll email you the file I have although I don't have a G74Sx notebook available to check it.

2. From reading the earlier posts in this thread though it sounds like Deanny really needed the 'full bios rom' to use with a bios programmer which ASUS doesn't post on the download site or provide, so unfortunately, I don't expect the '201' bios was able to help for the reflashing either since it is not a 'full bios rom' file.

What I did want to mention before you go out and buy a motherboard is that you may want to contact your local ASUS office to check if they can re-flash your bios without replacing the entire motherboard, but again, I'm worried that something may have gone wrong during the bios chip replacement (I'm a bit of a worrier) which would cause problems for this.
If you are in the U.S., let me know and I can discuss this option more with you, or check this ASUS contact page (http://support.asus.com/Hotlines.aspx?SLanguage=en) if you're interested.

Good luck!

Thanks for the response, unfortunately as it was a 2nd hand one off ebay i don't think it has the g74sx.bin file as it looked like an oem rebuild copy of win7 on it and didn't have the g74 specific drivers loaded etc, and of course no discs were supplied with it, but i will have a look and see if the file is there for sure, I'm fairly certain the bios swap was successful as far as re-soldering etc and no other components were damaged, its actually working better than it was before the swap it gets lights and things now just dosen't post, where with the original bios i got absolutely nothing, so I'm hoping the 201 bios will overwrite the failed 203 portion and restore it to original. Anyway will send you a pm if i cant find the bin file thanks again.

Ok, so have tried the ctrl + home thing one more time before ripping out the HDD and it got to post, so relieved! however it booted saying " Reboot and select proper boot device, or insert boot media in selected boot device and press a key" am afraid to touch it from here incase it dosent come up again.

So is this asking for a normal boot disk or a bios rescue? (given i started it with the ctrl + home method)

Thanks in advance.

All fixed, was hdd boot partition, thanks for your help.

Also for future reference if anyone else manages to brick there asus (not hard to do) i bought a replacement bios from ebay off this guy http://myworld.ebay.com.au/bios_store/&_trksid=p3984.m1439.l2754 was about $20 inc post and just used a hot air soldering iron to remove and replace the bios. so if your stuck and good with dismantling the laptop and using a soldering iron, do that! not sure why it didn't come up to start with might have had to do the ctrl + home method to bring it back to life? anyways looks like its all good now.

Glad you could solve it Clint82 and thanks for letting us know how it went.
Yeah, wondering if the CTRL+HOME would have worked with the original bios chip, but as you mentioned, it seemed to be working just a little better with the replacement bios, so maybe it would not have worked with the original bios chip anyway.

Hate to Beat a dead horse here guys, but I'm looking to revert to 201. The back lights went out a while ago with no explanation, and i saw somewhere that it'll usually fix it or at least is an option to try. I upgraded BIOS to try to fix it already, and I'm running 203. My back lights still don't work, My NumLock light is stuck on, and my Keypad no longer works in game. I assume if I just revert BIOS to stock, it may help all of this. Does anyone have the original BIOS, or know where the download is. I've been searching Google all night.

Haven't worked much with the G74Sx myself, but not so sure that the 201 bios will be able to help with your keyboard lights issue, so just make sure you want to take the risk of a bad bios flash for it (sorry, I'm a worrier).
If the keyboard lights flash as soon as you power on the unit to indicate the hardware is okay, we should check the software more first though.

Anyway, according to earlier posts on this thread, if you still have the original ASUS factory installation, the G74SX.BIN file hidden on the C: drive should be the 201 bios version, so let us know if you still have it.
If are you interested, you can also send me a PM at cl-Albert to discuss more.

My G46VW had the same problem.

I was shopping at Best Buy on 01/18/2013, NY and had trouble 10/11/2013, as I live in Brazil had to send it to ASUS USA for repair.

After five months it returned working but to my regret, the same problem occurred again after 2 days of use.

I've tried the suggestions in the post, but nothing I tried worked, left as a last option, replace the BIOS chip.

In the region where I live I did not find anyone who provides the service, so I would know exactly what the procedure for replacement, including equipment needed and where I got a BIOS chip for this model.

The ideal would be to get a chip already recorded if possible.

Could anyone help me?

Can someone please send me a link to download the original bios 201 for Asus G74Sx?? Or, is there a way I can extract the original bios from my recovery factory reset partition?? My optical drive and back-light stopped working few days after updating the bios.

Thanks

Screen Backlight or Keyboard Backlights?

I have G74Sx too, I have a bios you can use to restore the keyboard backlights.


I believe you can hold CTRL + HOME before and after pressing POWER, to reflash the bios on the recovery partition.

If you do manage to extract the bios would you please share a copy, it would be nice to have a copy of 201 just so I have it on file.

Also check the link on my sig for a thermal mod bios. No more throttlestop :)

I don't have bios 201.

I used a buspirate in the end to get my g74sx going again. I don't think it checks to see if the bios is valid anyhow so the CTRL+HOME trick should work with any version named as G74Sx.bin, If your laptop doesn't post the CTRL+HOME thing might not work, didn't for me anyway. You'll need to send to ASUS or reprogram yourself with an SPi programmer, is easy if you follow guides on the internet.
