[REQUEST] HP G62-b00 series (Intel) BIOS Unlock

[emimilu]

Guys, i made the flash yesterday with the modified BIOS. Then, my notebook wasnt turing on anymore. So i wanted to fix it with the original BIOS, but then i had a lot of trouble to make it, thats why i want to help for people like me:

First, you have to go to your model name on the original HP web, and download the so called "BIOS Update Unified Extensible Firmware Interface (UEFI)" than, install it, and choose USB option. Now you have your USB prepared. (some people say it has to be at most 2 GB).

Second, you have to download the original BIOS. At that point i ahve to say, that for my model, there are several BIOS option at the HP web, first is the normal bios. (and old versions) But we need the so called : Winflash blbabla Bios, which contain the only BIOS that worked for me. So download it (F.08). Once downloaded, unzip it with WINRAR. Now you have a folder with the original BIOS. Rename the .fd file to .bin.

Third, download the Phonix Mod v.2.11, install it, and aply it to your .bin file. Now you will will have a xxxx.bin.dec file and a RSA.SIG. Copy these two to Current folder of your already prepared USB stick, then rename xxxx.bin.dec to xxxx.bin, and RSA.SIG to xxxxx.SIG (the same as the previous .bin file). Example:

01439.bin.DEC --> 01439.bin
RSA.SIG ----> 01439.SIG

FOURS, unplug everything (batery, power, USBs), then, plug the power cable on, and then the USB stick. Now, turn on your computer, everything should go just FINE) IT IS NOT NECESARY TO PRESS WIN+B or ANY OTHER BUTTONS (G62 models)


ENJOY YOUR OLD BIOS

READ AND RESPECT ALL STEPS

            I did exactly how pere00 said for blank screen but running fan (I initially suspected gpu problem cause my keyboard does not have the caps lock LED) on HP G62-a80sv. Make UEFI usb stick with 52264 tool from HPSupport/model nr./bios on Windows 7 computer. Download also from the same place (HPSupport/model nr./bios) 49367 (F0B) bios update. Unpack the 49367 with winrar or 7zip and you will see some files. Rename 01439.fd to 01439.bin. 
            I use Phoenixtool266. Open the Phoenixtool version what you have. On the "Original bios" choose the "01439.bin" what you just modified. On "Manufacturer" choose "HP", on "Slic file" choose "HP.BIN" and now the "Go" button is not locked anymore and press it. You don't need to modify or to press anything else. When you see on the "Status" field "Success", you're done with this and you can close the tool.
            Now, go to the folder where you extracted the file and you will see among other files 01439.bin.DEC and 01439_SLIC.bin.DEC. Copy this two files on your usb stick, on folder Hewlett-Packard/BIOS/Current and rename 01439.bin.DEC to 01439.bin and 01439_SLIC.bin.DEC to 01439_SLIC.bin.
 SAFELY REMOVE the usb stick NOT UNPLUG.
 Plug the usb stick on the dead machine (with the HDD disconnected), plug in the power adapter, press the power button and pray. 
You don't need to press any other button.
The computer will start and stop every 3-4 sec for about 10-15 min (with the black screen) and .....on my case goes ALIVE.
After the computer starts normally you can upgrade your bios to F35 (50335), or how i do directly to F48 (55430) via windows.

Hi there!

My laptop always has the CPU fan 100% since a few days, from turning on until I turn it off. It is not because of the heat (it stays below 50 degrees Celsius), it is not because of the CPU fan (is new, I thought it was because of it, but the previous CPU fan also happened), is well ventilated and cleaned... Maybe it's a faulty thermal sensor?

I don't know what to do, it is a fan of 3 pines so only the BIOS can modify its speed... That's why I thought that maybe a modified BIOS could help me, it's very noisy... 

The exact model WAS HP G72-b30ss. BUT the installed motherboard I think is an HP G62-b85SS, because it says so in the BIOS. (XF219EA#ABE). 



Thank you a lot!

Does this motherboard not use Intel Internal Graphics?

Sorry for late reply. Did the exact same thing.  Can't find a working link to the bios,  it is crap.  I went 4 months without this thing for something extremely dumb.  I forgot to put thermal paste on.  It would keep turning off.  I ended up getting an i7- 740qm in there, just fine.  Clarkdale works,  although it is not in the official cpu supported list, bios modded or not.

Hi, fuducker81 & kocoman

I own a HP G62-B85SS laptop, running Windows 10 Pro.

Intel i3-350m processor with HD5470 512MB discrete graphic, switchable with Intel HD graphics
MainBoard 143A 60.50 & F48 ver. BIOS

G62 & G72 Intel based laptops seem to have different models of 143A mainboards, here in BIOS-Mods a user of a G72 bricked BIOS has a 143A 60.22 mainboard.
This may be the reason why some 143A mainboards accept Quadcore processors and others not.

Could you post your CPU-z mainboard especifications, BIOS ver, SO your runnig, etc... fuducker81?

By the way is it worth to upgrade from an i3-350M to a i7-720QM?. On Ali yo can get one from 15€

Or in the case my maiboard is not compatible with Quad processors, Will be a i7-620m an improvement? (upgrade from dual core to dual core)

Thanks
