Here's a bunch of frequently asked questions: Q: My laptop is blocked with a BIOS password. Can you unlock it? A: If the stuff does not work, please use the vendor support. Please note that I have chosen not to publish generators for newer models. Q: I have used your generators, but the generated passwords fail to unlock my laptop.

Can you help? A: No: please use the vendor support. Q: Can I buy passwords/generators from you? Q: Can you unlock my hard drive/Windows installation/cell phone/apartment door? Q: Can you teach me how to defeat BIOS password protection? I received numerous emails in the past from owners of Fujitsu-Siemens Amilo Pi laptops that got locked up beyond recovery: in a nutshell, a BIOS update or some other minor event has caused the password checksum to be overwritten by a seemingly random number above 2^14 (16384).
In conjunction with the butchered CRC16 implementation courtesy of Phoenix, this basically means that there are no valid passwords for checksums above that number, i.e. The laptop has become an expensive paperweight. However, there is a small backdoor, and that is the BIOS emergency recovery: it's basically the last resort to recover from a bad BIOS update. I've patched out the password check from the binary so it can be used to reset the machine to a valid password. Here's a quick how-to: •.
Copy the BIOS file (,,, ) as 'bios.wph' to the root directory of the floppy. • Remove the battery and power cord from the laptop.

• The BIOS is being reflashed - after that, the machine should reboot on its own. • When it boots up, go to setup and set new passwords. If you get asked for a password, just enter a few random characters. • Boot the laptop up again, re-flash the vendor BIOS. • Go to the BIOS, reset all passwords.
That should unbrick your laptop. Mtmarco has posted alternative instructions on. It has the same quality as: he modified my code a bit (removing the GPL license, attributions, etc.), claiming this time that it can calculate Toshiba unlock codes, and sold it to some guy for $460. Interesting, the payment went to 'Luis Eugenio Davila de Garate'. He probably has burned his personal paypal account and is tapping into the account of a relative now. In other news, are some of his clumsy attempts to advertise on youtube, and is a fan site which he created with all of his skills in a pretty lame attempt to extort me to retract all the information about his scams.

Surprisingly, it was even easier than older models: Dell Laptop Master Password Generator. Copyright (C) 2011 dogbert; 2007-2010 hpgl Short service tag should be right padded with '*' up to length 7 chars HDD serial number is right 11 chars from real HDDSerNum left padded with '*' Some BIOSes has left pad HDD serial number with spaces instead '*' Input: #ABCDEFG-1D3B 22:42 DELL service tag: ABCDEFG-1D3B password: xvn0qEeftqyrkG52 In light of this (and ), a pack of monkeys looks sophisticated in comparison to Dell engineers. Also, please don't even bother to send me emails: you're just wasting both our time.
P.S.: DELL service tag: #NOSOUP4-3A5B password: zvd97y9h P.P.S.: has a free password generator. A few weeks back, I ditched my iPhone for good and got my hands on a used Palm Pre. Unfortunately, it was net-locked by the provider. Fortunately, the modem is Qualcomm device and hence, all security features can be bypassed so easily that they appear meaningless in the first place. I've written unlocking scripts that work on every webOS phone, i.e.
Palm Pre (Plus), Palm Pre2, Palm Pixi (Plus), HP Veer, or HP Pre3. You do not need a SIM card for obtaining the unlock code, and the unlock is perfectly safe, i.e. You can't brick your device.
Here's a quick how-to: • Install python 2.6.x (32 bit/x86 version):. Python 3.x will not work.
• Windows: Install pywin32 for python 2.6: • Install pyserial: Linux: Use your packet manager to install the required libraries, e.g. Sudo apt-get install python-serial for Debian based distributions (Ubuntu, Mint, etc.) • Download the unlocker (, or ) and unpack it (e.g. Into the directory C: unlock) • Calculate the USB passthrough key: go to device info, write down the 'Serial Number', and use pre_keygen.py to generate the key from this number.
The serial number is also printed on the back of your device and/or underneath the battery. • Start the phone without a SIM card, then start the dialer. If the phone has not been activated before, you can either select 'emergency call' with the icon from the notification area at the bottom (Pre, Pre2, Pixi) and delete the number ( 911, 112 etc.), or just type ' BZ' ( #*) blindly on the keyboard (Veer, Pre3). Enter '#*USBPASS# ( #*8727277#) in the dialer application and press the dial icon. A window will appear which asks you to enter the passthrough key. After you've done that, select 'Diag' for the ' USB PORT 1' (only for that port, the rest has to be set to ' None').
If you have trouble enabling the passthrough mode, the activation, install and install the 'Enable USB Passthrough' application from Preware. Erd Commander For Windows 7 Free Iso Burning. • Windows: Connect your phone to your machine and install for the serial diagnostics port (not the R-ACM or any other device).
The first time you plug in the phone in diagnostics mode, Windows will ask you for drivers. You can also force the driver installation in the device manager by right-clicking the unknown serial port under 'Other devices' and selecting 'Update drivers'. You might have to acknowledge a few warnings about broken driver signatures. Linux: Insert the module usbserial module with vendor and product parameters matching the vendor and product ID ( lsusb), e.g. Sudo modprobe usbserial vendor=0x0830 product=0x8043. You have to make the device file (usually /dev/ttyUSB0 ) accessible to regular users, or you have to run the unlock script with root privileges. • Run pre_unlock.py / pre3_veer_unlock.py and write down your network unlock code.
If the serial port is not found automatically or if the search is stuck, you can specify it as a command line parameter. Open up a, navigate to the directory ( cd unlock) and run the unlocker, e.g. Pre_unlock.py --diagPort COM5 If the firmware version has not been recognized, to either the latest webOS 1.4.x or 2.x version. If you don't have a Palm account, you can obtain the updater. • Disable the passthrough mode: enter '#*USBPASS# ( #*8727277#) and press the dial icon again. Set 'None' for ' USB PORT 1'.
• Shutdown the phone. Put in a SIM card that is not accepted by the phone and boot it up again. You might have to. • Carefully enter the network unlock code obtained in step 8. If it gets rejected, please contact me with the perso.txt file that has been saved to the directory of the script. Reboot and enjoy your unlocked phone. If and only if the unlock code does not work for you (' Enter Unblock Code'), try running the script with the parameter --writeBack from the, e.g.
Pre3_veer_unlock.py --writeBack. After it has completed successfully, reboot your phone and it should be unlocked. If you need to activate your phone, but your carrier does not support data services, you can try.
The script should also work for Linux, MacOS, BSD and any other system which has drivers for the USB diagnostics mode and a python interpreter. I'd like to know whether this worked for you, so please leave a comment. Also, all sources of the unlocker have been released under the terms of the GPL. Feel free to hack away with them. Two types of companies exist: those which are growing and those which are dying. Sony clearly belongs to the latter for over a decade now. The high level of engineering that once made their products excel has been replaced by bland mediocrity and delusional control ideas that are manifested in recent Sony products such as Bluray, the PS3, etc.
In their latest act of desperation, they are suing a couple of guys who have successfully hacked the PS3 to bring Linux back to the console after it has been illegally removed in a firmware update. The flaws they used to obtain access to the multi-millon dollar security system can almost solely be attributed to crass design blunders that would have been completely avoidable in the first place. Sony has a line of laptops ('Vaio') which compete mainly in the high value market segments.
They implemented a master password bypass which is rather sane in comparison to the rest of the bunch: • The randomly generated master password is only stored in RAM, e.g. It's lost after the next reboot ('one time password').
• RSA is used for encrypting the password which is then converted to a human-readable form (4x4 characters/8 bytes/64 bits). • Their customer support apparently allows for one free password generation per device which is pretty decent by the industry standard. However, they screwed up by choosing a key length that is just 64 bit and hence too small: an unoptimized python implementation of a general number sieve yields the factors of the key in less than a minute.
With these, writing the generator script is an easy exercise: python pwgen-sony.py Master Password Generator for Sony laptops (16 characters otp) Copyright (C) 2009-2010 dogbert After entering the wrong password for the third time, you will receive a code from which the password can be calculated, e.g. 73KR-3FP9-PVKH-K29R Please enter the code: D63K-XFVF-TK7H-RJKX The password is: 43878945 I'm not the first one who discovered this: also reversed this scheme quite a while back.
There are even some idiots on eBay who sell these master passwords. Update: released.
