[REQUEST] Lenovo IdeaPad S405 Whitelist Removal

[Dashi]

I honestly don't know very much about flashing chips but I was asked to make a guide on how I succeeded in flashing a modded bios from this forum to my laptop bios. I do not take responsibility for any damage done to your device if you followed this guide.

Flashing your bios:

 I need help Flashing.
I have here an Acer Aspire E1-510P. running Windows 8 64 bit (if that matters). Once I turn it on, the power light comes on, the fan comes on, but that is all. no screen backlight, no sounds indicating its loading anything. I've taking the machine apart and put it back together, just to confirm that the Screen cord was not loose. I've done the power reset.... ive tried reseating the RAM and HDD.
At this point I believe the Bios may be corrupt.
I've tried to find a version of it that i can use to USB flash, but cannot. not even on the Acer Support page. They only have Bios updates for IN SYSTEM use... which is not an option for me.
If anyone can help me find a Flash it version of this BIOS or a modified one that I can Use with the chip clips, I would be eternally greatful. Thank you.
(I will put this into its own thread, just sounded like you people should see this cuz you sound like you know what you're doing.

Donate to me for my work and time . . . look into my Signature

Any chance to get this firmware? It isn't on rghost anymore (file deleted). I think it should work also for my S405, even if i have the AMD-A4 version.

I honestly don't know very much about flashing chips but I was asked to make a guide on how I succeeded in flashing a modded bios from this forum to my laptop bios. I do not take responsibility for any damage done to your device if you followed this guide.

Flashing your bios:

Step 1.
Obtain a modified bios.
The community is ready and willing to help you with this. If you don't have the skills, you can do what I did, and ask for a modified bios. Use the proper system that is already set to request a modified bios. [insert template link here]

Step 2.
Purchase the necessary equipment (Assuming there is no way to flash your bios without hardware.)
For my bios chip I needed a CH341A programmer and a SOIC8 SOP8 test clip. (Found them on ebay, it cost me a total of $20 USD for both items.)



Step 3.
Download the drivers and software for the programmer you purchased.
(The drivers and software for the hardware I purchased were located on the seller's ad page on ebay.) This step should usually be completed BEFORE plugging the programmer to your computer. Installing them before plugging the programmer into your computer will help avoid potential driver trouble with Windows. (I had some trouble installing the drivers and had to Disable "Driver Signature Enforcement" as the drivers were not digitally signed Looking back on it I maybe should have used a virtual machine but... oh well.) After installation, reboot your computer.

Step 4.
Connect the clip to the programmer and then plug in the programmer into your computer. Run the included software.

Step 5.
Identify the bios chip on your motherboard.
This was kind of difficult for me. I looked up a schematic of my motherboard to find out where the bios would most likely be located.




Step 6.
This step will be based entirely on the software that came with your programmer. I will show the steps involved in the software that came with mine.
Either enter in the exact chip information or, if the software you're using has an auto-detect option, you can use this, but I would recommend double checking. I went the lazy route and just went with the auto-detection. It worked well enough for me but I don't recommend relying on it.





Step 7.
Read the chip.
Read the current programming on the chip and make some comparisons to the original bios. This can be done with a Hex editor. Just make sure that it looks almost exactly the same. Remember, they should be the same file just with a few edits so they should still look almost identical.



Step 8.
Load the modified bios file and write it to the chip.
After loading the modified file, the tools I used only required I click an "Auto" button. This then took around a minute or two to write everything to the bios chip. If the program freezes, or appears to be doing nothing, don't touch anything for the next 10 minutes as you don't want to mess anything up if it is doing something.







Step 9.
Remove the clips and see if your laptop boots.

SUPER !!!!!
Many Thanks friend.

Hi,

Windows 10 corrupted my Dell Vostro 5470's BIOS and I tried the BIOS recovery with USB containing the extracted .cap file but there is an error that says

system pfat was enabled. please enter the signed image

ERROR 100 - Invalid BIOS image!

Now, I am trying to use this method to recover my BIOS to the original state. I am not trying to change any setting so do I need to modify the downloaded latest BIOS after extracted the .bin file to match with my hardware? Or can I just flash the extracted .bin directly to the bios chip? If i need to modify the extracted bios, can anyone guide me how? Thanks

Thanks for sharing.

I was able to flash a MSI desktop motherboard with the black version of the CH341A programmer and a test clip. On the condition to power the motherboard.
