Just fyi folks, I did the upgrade to windows 8.1 and that bluetooth issue persists(the one where bluetooth mysteriously disappears). Not only that, but there's a new desktop watermark that shows in the bottom right telling you that secureboot is off if you've disabled it. So you can either turn that back on to get rid of the watermark or leave it off so that the bluetooth destroys itself less often. I really wish this would get fixed. It seems pretty ridiculous. Has anyone found a combo wifi/bluetooth card that doesn't have this problem?

So I have the 7260 and I get that issue with bluetooth disappearing requiring a reboot. Is that something affecting all intel cards or any card on these laptops or what?

That's a good question, where can I grab the stock version of that vbios?

Still gives that error.

Just FYI to those wondering this is for flashing an ultrabay 750m in a y500 with the latest firmware on the y500 thread. On 5.142 I still get the PCI Block corrupted error. The older 750 firmware flashes but it doesn't seem to remove the 135 limit. The newer firmware throws that error. Edit : Same with the dos version. Edit 2 : Somewhere in all this the older 750 firmware worked and now shows up with the proper (MODIFIED) label in inspector with the limits properly removed. So I think I'm good despite the newer firmware not flashing due to that error. It just means I have different versions between my onboard card and the ultrabay one.

Yeah, I used the -r command first. Like I said, I can flash one of the two 750 firmwares, just not the newer one. The one I can flash doesn't seem to remove the 135 limit that I can tell.

I haven't been able to successfully flash the newer 750 bios on the ultrabay card. I get the following result when calling "nvflash -6 -i1 vbiosOC.rom" This is in the windows version 5.134 as 5.128 refused to even attempt flashing and said I needed a newer version to flash that firmware.

Anyone else have any trouble with it?

No, I didn't install from 2.02 and I don't recommend that.

Yeah, no worries there. My main desire was the whitelist removal so I'm good to go.

I just installed the 2.03 mod and can confirm it worked. I didn't realize just how locked down the existing bios was until I saw the unlocked one.

Has anyone actually sent a firmware backup of 2.03 or 2.04 to svl7 yet so he can work on it? Is the backup something that's moddable or do we need to wait for the newer versions to get leaked like 2.02 was?

The modded 2.02 bios seems to be missing from the first post attachments. I don't need it since I'm on 2.03 and will need to wait for that version to get modded, but I just thought I should point it out.

Generally because the 2230 card has some pretty well known issues with speed and consistency of connection for wifi. The card should hit a max speed of 150mbps but most people rarely break 20mbps. Newer drivers have helped some. Disabling bluetooth has helped some. But it seems to be a hardware issue with the card and some people would just like to be able to replace the card with a better performing card. On top of that some people want to be able to use 5ghz connections and the card doesn't support that. That is useful for those people stuck in areas that have the 2.4ghz band flooded with competing signals(like 20 neighbors with wifi routers of their own).

I'm glad you posted this. I've had mine apart and I've already noticed one of the screws was loose.
