I don't know the details tbh.... there are threads here somewhere. It is, the problem with some HPs is the BIOS is signed and therefore wont flash when modded Andy
Serg008: I've been searching some articles regarding how to mod the EFI BIOSes with the MMTool (2.0+ for EFI) and the Hex editor... so far I was only able to find how to extract and replace modules. I placed an order for a new Mobo and need to mod the BIOS. It's a Gigabyte Z77MX D3H V1.1. After using the PhoenixTool, I was able to dig through the DUMP folder but couldn't find anything in there even by using the Module method for a mod. Matter of fact is the Hex editor told me the original and modded BIOS files are identical. So I started to play with the MMTool. With a modded F14 BIOS posted here, done by you, I scanned it with the PhoenixTool, which it reported to me that it has found a pubkey, marker and a SLP support model. I extracted them using the MMTool and inserted them into the newer F15 BIOS. After scanning the Modded F15 BIOS, the tool reported back to me three modules I extracted are present in the newly modded F15 BIOS. I opened the extracted pubkey and marker BIN files, none of them looks like the SLIC dump I seen on the forum. My question is, am I doing it right? Or what I got here is a brick-guaranteed mod? I have searched left and right, but I couldn't find anything on these tougher-than-usual to mod BIOSes... We need your information, if you don't mind share with us
Also Andy: Thanks for your great tool as well! I just want to share that after finding your post in this thread, number 3194 (can't post link yet) regarding uncheck "only change tables in ACPI" and other options, I was able to mod the Gigabyte Z77MX-D3H ROM, which is an AMI UEFI. Turns out it was identical to the one I modded earlier with the PhoenixTool default options and then manually added SLP support, pubkey and marker module using the MMTool. My question is, I don't see no SLIC table anywhere. I mean with your tool I picked a HP bin, with the MMTool extraction I have no information what type of BIN was used as it was extracted from an already modded ROM. So how can I check? Will the SLIC table show up as uncompressed or, at least some sort of header I can search for? Nevermind, after opening the successfully modded ROM with the PhoenixTool, it has reported it has found the OEM Table, Pubkey and Marker in there. Thanks again
Hello everyone. I have a problem with my Asus K52JB and I'd really appreciate your input on this one. I tried to flash the latest bios update (208) and something went terribly wrong. Now my computer is totally bricked I push the power button and nothing happens, no lights, no nothing. Something is weird. I opened my laptop and although on the back it says MB ver.:K52JB in fact it is a K52JR WTF?????? I ran Andy's tool and here is my mobo info: EFI/Insyde bios Recovery filename: k52jb.bin pubkey(x2) MArker(2.1) (Asus_notebook) (x1) I tried a couple hotkey combinations for this model but nothing seems to awaken it... I already have a flash pen formatted to Fat. Can anyone help out on this one? Thanks
Thanks for your answers. One more question. I went to some computer repair shops and every time I talk about chip programming they give me that face "wtf is that?" It seems I know more they do... Anyway, is it possible to buy a new motherboard and replace the old one? I believe it will do the trick but just to make sure. I can get one from china for 120 bucks, so what is your input?
If you can afford new board, then get the new board. Your laptop doesn't turn ON at all (no power), there is no guarantee your laptop will turn ON after recovering the BIOS using programming tool. I have never experience this kind of problem myself. My laptops when bricked, it at least can turn ON (but with blank screen of course).
