Chris Lu and I originally wrote — and did — this around December, The article has been preserved for posterity. In an attempt to replace the built in Broadcom wireless card in Chris' laptop with an Atheros card, we came across this evil firmware hack on our own.
In this paper, we will detail the method that we used to defeat this lockout.Lenovo G400s, G500s How to unlock bios whitelist / Como desbloquear Whitelist da bios
When the PC was first designed, it was designed on the premise of expandibility. Architectures were standardized for the express purpose of creating a platform that anybody well, anybody with the time and money to do so could build on top of. As time went on, the platform became more versatile — computational power increased, electrical power consumption decreased, size decreased, and expansions that nobody would've even conceived of sprang into existance. The computer market thrived on competition between multiple manufacturers who wanted to provide an expansion that did the same thing.
But over time, computers tended towards becoming more integrated machines — black boxes, if you will. Consumers began looking for one box that they could buy that did everything that they needed. With this trend, manufacturers began shipping inferior parts with computers because they could get away with it. Sure, the user could go out later and buy a more powerful replacement, but they had still given their money to the original manufacturer for the less powerful part.
The industry continued to thrive, offering upgrades for users who wanted them. Recently, though, manufacturers have started down a worryingly slippery slope.
We found that out the hard way when Chris bought a more powerful wireless card for his laptop. System halted. The system powered up, and found that a wireless card existed. We saw this as an affront to the history on which these computers were developed, and began searching for a way to circumvent this restriction.
The card that we wished to insert into this system was an Atheros-based wireless card that did not have the appropriate bits set to have the HP BIOS recognize it. In the past, we tried modifying the BIOS as mentioned on Garrett's sitehowever our success was limited. We managed to complete all steps from 1 to 5; however the latter part of the 6th step unfortunately applied.I would appreciate if you could let me know how you did that so I can get my WiFi card working here I have discovered a location that contains "updated" Bios versions for various machines and model, where the whitelist has been removed.
I rolled the dice because I could not stand the Ralink RT any longer. Edit: I spoke too soon. I installed it and it worked for 2 days, then would not turn on in Windows red x over the wireless icon. I did everything I could, but nothing worked. Put the old card back in and it was ok. I then returned that one and got a replcement. Same thing! This time it worked for 1 day and then stopped.
It'srecognized in Windows device manager and everything, latest drivers, latest bios, but red x.
It is NOT doing the post thing where it says unsupported hardware. It literally works perfectly for a day or two then dies. Oh well, back to crappy WiFi. It is allegedly compatible with G3 model.

So it comes down to BIOS. Corporate fascists want us to spend money to their latest laptops. So if a replacement part is FCC compliant, it should work in a computer. Didn't find what you were looking for? Ask the community.

So i decided to upgrade my wifi card intel to a new Intel wifi card which supports the Unfortunately i discovered that HP uses BIOS based wifi card whitelists to prohibit the user to upgrade the wifi card.Apeman c450 manual
When i bought the notebook HP never mentioned it. HP advertised that the notebook has a mini pci express slot. Therefore i concluded that every mini pcie standards compatible wifi card would work.
Which models are using a whitelist? HP provide service manuals for its products and you may find all compatible components in there. The whitelist contains all the part numbers from the service guide so when you want to upgrade a laptop, find the component in the service guide or choose the best you can get if more components are available. There is an Intel The part number is: for the US etc, see the manual for the right pn.
It is like buying a car and the manufacturer tells you that you can only use a certain brand of gas station. Also the Notebook and the wifi card advertise to be Wi-Fi Alliance certified.
That means they have to be interoperational. If not they are not WiFi-Alliance certified or the certification is not valid. If you want to replace a light bulb you can use any light bulb which operates in the spec and has the same socket.Free ir packs
Because thats why a socket is a common norm. On the other way round you can use your certified wifi card with an external antenna and have maybe a higher EIRP output. So you can violate FCC regulations with a certified wifi card. Computer old ishneed new component? Why don't you simply upgr Buy a new system instead.

[Guide] Bypass HP/Lenovo Laptops Bios Whitelist NO BIOS MODS Required
Still here? The downside to this is that you need to install the bootloader grub2. Some vendors have a nasty habit of applying so-called whitelists to their products. These whitelists tell the BIOS what hardware is allowed on the machine in question.
All non-compliant hardware will be disabled. For example: I had this Realtek card in my HP s, but the stoopid thing was so unstable under Linux, that I decided it had to go.
So I bought an Intel card and installed it in my laptop, because these cards are properly supported in Linux. Upon boot the BIOS told me the following:. The 'system' did WHAT? Indeed; Booting either Linux or Windows showed no wireless card present in the laptop. Consulting Dr. Google showed me that whitelisting was something quite common nowadays and that lots of people were being frustrated by this most arrogant vendor behavior. There is much to be found online about BIOS modding to get around whitelisting.
But the BIOS images of an HP s is encrypted and I dare not even think how many hours of midnight hacking it would take to get around that. I did give it a short try, but soon decided that I would try to find another way around this. So I re-fitted the Realtek card, booted Linux and took a look at what devices are on the PCI tree: lspci grep -i bridge MS Host Controller rev 30 Device The important thing here is ' I then replaced the Realtek card with the Intel card.
Again, on reboot, the BIOS complained about the 'not supported' card. Again I booted into Linux and checked the pci tree. Where did number 25 go? The Intel card was still physically installed in the laptop, so the BIOS must have disabled it somehow. So I decided to dig deeper. Let's see what pci chipset is installed A quick google for "Intel Series 6 C" yielded the datasheet of the chipset.
I download and opened it and Oh dear, that's alot of information right there. Luckily a quick search for the term 'disable' immediately lead to this:. A disabled function can only be re-enabled by a platform reset. This could be interpreted as that once a function is disabled, the system needs a reboot to be re-enabled.
We'll find out soon enough. So I have an offset address and a bitmap. So I checked out the very first paragraph of chapter 10 and it read:. This translates to Device 31, Offset 0xF0, bitrange Reading the first paragraph of chapter 13 then gave some more info on the base of that offset, confirming what was discovered:.
At this point I was ready to do some actual PCI hacking.I would like to enquire about the suitability of replacing the existing Wi-Fi cards on two HP machines with Intel Dual Band ac cards.
The models of the laptops in question are listed as follows:. I would appreciate any evidence if you own the same or similar machines and have undergone a similar or the same upgrade just to put my mind at rest prior to making any purchases, however, I will appreciate any replies that may be unsubstantiated but that may be informed from a technical perspective or simply from experience.
Go to Solution. The J, yes, you can install the AC, if your notebook has two antennas currently attached to the wlan card in there now. Other forum members have done so successfully in the 15t and 17t-j notebook series.
The esa, probably yes as well, if the notebook has two antennas currently attached to the wlan card in there now. Now they make things just as difficult Now what I would do if I were you, would be to order one card for the j, and try it in the e If it works, then get another one for the e Then I pop in the card I want to test, and if the BIOS doesn't reject it and it shows up in the device manager as a network controller, then I know the card should work once I attach the antennas and install the drivers.
That way, I am not messing around removing and replacing those delicate antenna connectors more than I have to. I've got some good news for you and for any readers curious to know about the results of my wlan card upgrade to the Intel ac card. Thanks a lot for encouraging me to perform the upgrade, it paid off I now get my full internet speeds from my home hub. If you have not done so already, don't forget to install the Intel bluetooth driver for those cards.

It is a great resource for information, tips, and solutions that have helped others. I grasp that you would like to update your wireless card to one that support Bluetooth. You tried updating the bios, but there was no change. You would like assistance in altering the bios. Please note chapter 3, page 26, item 20 for the recommended wireless cards replacements, that have been tested and known to work with your model. To show appreciation for my help. Modifying the BIOS is very complicated.
If you just need to add bluetooth capability then I would get a bluetooth USB adapter. FYI just cause the bios is when it was made two years ago it was and they most likely never changed the wifi whitelist since that time. So the system laptop had to be made with Win8 or later part of to have no whitelist. You should look closely at the Service Manual link to see what is accepted wifi for your system.
Modded BIOS is not something we support or help with. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:. Operation is subject to the following two conditions:. This device must accept any interference received, including interference that may cause undesired operation.

All forum topics Previous Topic Next Topic. New member. Message 1 of HP Recommended. I bought one HP laptop two years ago. The model of my laptop is HP Pavilion 15 etx. I found bluetooth is not supported by the default wireless card with the model Realtek EE. So I wanted to change the wireless card by BCM But when I booted the laptop after I changed the wireless card, it showed "Unsupported wireless network device detected.Around two years ago, I posted this article decrying the whole situation where several laptop manufacturers have imposed artificial restrictions in the BIOS firmware against replacement of wireless cards and other hardware with other physically compatible units from other sources, or of different models not originally equipped as standard.
The article itself did explore the possibility of breaking whitelist protection using a method that donovan posted extensively aboutbut the project hit a stumbling block when the modified BIOS could not be loaded back onto the hardware due to the use of RSA key signing on the flasher itself. Not knowing any more, I abandoned the project and continued with my life. Fast forward to Mayand I was contacted by a reader by the name of Dragy who was also facing some whitelisting problems.
He was adventurous enough to take things further, and was able to develop a successful method to overcome the whitelist protection. He generously sent me a few long e-mails detailing the whole procedure, with explanations about why things were done in certain ways.
He very generously volunteered the information in the hope that I could independently verify that the procedure works, and post about it so that others may have a chance to address their own problems.
The following post could not have been made without his help. As usual, readers should think for themselves before taking any action, and furthermore, have appropriate back-up plans for when things go wrong or get damaged.
I will not be held responsible for anything that ends up happening. As the former effort was thwarted by the process of actually restoring the BIOS to the laptop, Dragy thought to bypass the whole flashing issue by using a few tools. The output is to a DIP row of pins, which fits into a programmer. Pin 1 is identified by the red stripe.
Project Dirty Laundry - How to defeat whitelisting without BIOS modding
Although the IDC header is pins, only the top 8 are used, which is normal. The top half of the socket is for 24 series I2C chips, whereas the bottom half is for 25 series SPI chips. Of course, aside from that, you will also need a compatible wireless card that you want to use in the system that is affected by the whitelist protection. To begin, we have to pull everything apart.
First step is to take out the battery, and then undo the four screws which allow for the decorative panel with the power button to slide off. Two screws have to be undone to allow the keyboard to slide up and then out. The flexible flat cable needs to be unclipped and removed. Install the new wireless card, and temporarily attach the keyboard flex again. Plug in AC power and boot the machine to confirm it is blocked by the whitelist. Make an exact note of the message.
Unclip the touchpad FFC, and undo three screws to slide the palmrest and touch-pad assembly off to the right. Undo all the flexible cables connected to the motherboard, including the display cable, the webcam USB lead, two antenna leads, power button PCB and speakers. Twelve Torx screws and one Philips have to be removed, then the sides carefully unclipped. To continue, two screws need to be undone — one releases the audio jack board, and the flexible connector needs to be unclipped.
The other screw releases the motherboard assembly from the case. To completely free the motherboard from the case to make our job easier, two cables have to be detached. At long last, 38 screws later, we have a clear look at the BIOS chip.Blank pdf email attachment
The chip is partly covered by a label, which normally says the revision that was flashed at the factory F. The driver must be installed first, then the software run.
I found a screenshot of the English version hereso at least you can refer to that to help understand the software. The adapter needs to be fitted in the lower half of the socket closest to the USB connector, with pin 1 oriented away, like so. The voltage on the adapter was pre-configured correctly. The arrangement is quite precarious, so it pays to have everything on some steady bench with a USB extension lead.
Positioning is crucial, and bad contacts will lead to unusual behaviour. To check if your contact is good, you should click on the Detect D button, where it should show the correct manufacturer. If not already, set the chip type to the correct or closest match.
It takes about 20 seconds to read the chip out, and then you can save it as a.
