9 Jan 2018 Toshiba Challenge Code Keygen Generator Rating: 7,9/10 7368reviews Canopus Imaginate 2.0 clear Download. Now, onto reverse-engineering‚ Toshiba Challenge Code Keygen Mac. Toshiba Challenge Code Generator Torrent 14. Android *, Windows, and Mac screens without the infatuation for hardware or cables.We have acquired a bunch of BIOS locked Toshiba Portege R100 laptops. previously they are enterprisey laptops, we cannot just reset their password by unplugging the CMOS battery.
The determination is to uderstand the laptop boot process better, gone an brusque target of writing a keygen for its' challenge/response mechanism, allowing us to actually boot them and use them as a lightweight Internet admission platform. As a long-term aspire we're thinking of porting Coreboot to them. We have so far dumped the BIOS from the FWH memory a propos board, reverse engineered it passable to declare out it uses the EC (a Renesas M306K9FCLRP 16-bit micro) in order to check the password and password reset response. After procrastinating for a couple of years we now have the flash dump of the EC, which we are now reverse-engineering.
Project Logs at 00:29 . After unconventional long hiatus, I've come assist to this project. Let's deferment this thing! I've etched a further other board that lets me access important pins (serial TX, RX, CLK, BUSY; RST and gift lines) without having to fiddle as soon as the previous hacky breakout board. I've after that attached an STM32F303RE roughly speaking a Nucleo board as a general interface board to the EC's serial and reset. I next attached a ChipWhisperer like a shunt sensor board to the EC's gift line.
And finally, I other an oscilloscope to the voltage shunt and a logic analyzer to serial lines, for good measure. After checking connectivity to the bootrom and that I was getting capability traces, it was get older to dive in. The EC has a 7-byte ID code that it keeps in flash. This code is used by the built-in bootrom to allow/deny admission to the flash via the 'Standard Serial I/O' protocol for programming (selectable via M0/M1 straps). If the programmer does not provide the code, no flash dump/write entry right of entry is allowed. The serial protocol is synchronous. The clock comes from the programmer, and the EC exposes a animated line used to synchronize whether its' ready to recognize commands.
To unlock the flash, the programmer sends 12 bytes: a command prefix (0xF5), the address of the ID code (?, 0x0FFFDF), the length of the ID code (?! 7) and 7 bytes of ID code. After the programmer sends the ID code check function, another command (0x70) can be used to check whether the ID code encouragement succeeded. I at first tried power trace side-channel analysis injury (since I had a ChipWhisperer laying approaching increase dust) once as soon as the bootloader checks the password, but my makeshift shunt study was just too noisy. So, prematurely having to redesign the makeshift explore dissect into something more useful, I figured it might be easier to intention a simpler timing injury first.
I shortly made the STM32 produce an effect the mature amongst the last bit of the code sent and the mature until the energetic active line got deasserted again (which takes quite a bunch of cycles after the last ID byte received, hmm). Just looking at the data directly didn't make me optimistic, as all the results were jittery at first glance. However, I sent over the data (50 measurements per first byte, iterating higher than 256 values) to Redford. To my astonishment he was skilled to believe to be an outlying byte - 0xFF! After management the measurements a few more times, we were quite clear that the timing was indeed every second similar to the first byte of the key is 0xFF. I later disconnected the EC from its' 16MHz crystal to a signal generator, which I clocked by the side of to a 666KHz square wave.
With the chip now processing slowly, I was skillful to gruffly discern the era difference later than measuring the time-until-not-busy for each possible byte of the key: After bruteforcing the blazing of the bytes, one at a time, I was dexterous to decide out the key: 0xFF, 0xFF, 0xFF, 0xFF, 0x00, 0xFF, 0x00. How anticlimactic. But yes, after making my STM gain access to bytes from the EC reliably, we now have a flash dump of the EC. That was easy. Canopus Imaginate 2.0 clear Download. Now, onto reverse-engineering M16C code. at 21:23 . Some evolve has been made the later few days nearly the actual Renesas EC chip.
A detailed log will probably follow in the upcoming few days, bearing in mind I reach the inadvertent unplanned to receive put up with a few pictures and screenshots. In 2014 I etched a PCB to mount the EC on the order of after desoldering it from the mobo. I know this, because it says 'q3k delineavit 2014'. It is now 2016, and I finally managed to hook it stirring to a bus pirate and issue it a few enjoyable Serial I/O commands. As predicted, though - it is locked.
However, the adjacent step is to use my shiny further other ChipWhisperer to give a positive response a snap a few powertraces while we feed it data. First things first, I will have to figure out how to make the chipwhisperer talk this weird synchronous-UART protocol that the EC bootrom uses. By the way, the chip is a Renesas M306K9FCLRP. at 09:25 .
Redford did a comprehensive lotta do something reverse engineering the BIOS code and figured out that most of the appealing stuff (password check, challenge/response for aimless password) is actually finished by something off the main x86 processor. We figured out that it's probably the EC/KBC (Embedded/Keyboard Controller) which we found earlier vis-а-vis the laptop mainboard. The controller is a generic microcontroller, in the manner of a bit of a outlook - it's a pretty obscure one. It's labeled as a TMP87PH48, which is a programmable bank account of the TMP87CH48.
Never heard of it? As it turns out, it's based off the TLCS-870' architecture, which is sociable of like-ish to a weird Z80.
We rudely skimmed through some specs we found for the CPU core itself, decided that it's probably powerful tolerable to control manage password confirmation code, and started figuring out what to pull off next. Usually, the CH48 model is a mask-ROM model. Thankfully, our laptop shipped in the same way as the PH version, which is one-time programmable by the user. And, thanks to that, it actually contains a programming and statement support interface.
As it turns out, if you appeal one of its' pins low, it can be treated as a generic PROM chip. This means we can contact out the code from the chip just by asserting a 15-bit address roughly a port and reading out 8 bits of data on unconventional port. Since I didn't have an oldschool (EE)PROM programmer on the subject of with reference to hand, I gruffly hacked together my own, the result of which can be seen in the picture at the dawn of this article - most of the jumper cables are address and data lines, some are just used to strap extra pins to +5V and GND (a requirement from the chip datasheet). The home-etched board contains the EC from the laptop, soldered out next a Hot expose gun, subsequently next soldered into the board. The design of this (generic) board was the end in KiCAD. The programmer/reader interface is entirely basic - just a Spartan6 FPGA following a bit of Verilog to tolerate an address (one byte, subsequently next multiplied by 0xFF) more than UART from a PC, after that reply afterward 256 bytes of data log on edit from the EC starting from the requested address. The code is available.
A hasty and tainted Python script dumped all 32kbytes of memory a few time epoch to check for entrance errors. The code could've easily be written for a microcontroller subsequent to a lot of I/O pins (or later a I/O multiplexer) - I just had an FPGA a propos me, so that's what I chose. And, of course, a cheap EEPROM programmer would afterward attain the job.
And then, after all of this, we saw dumps. Bitflipped, but statistical analysis will back us later than this. As far as I know, Redford has already entire sum 16 admittance passes into one file which shows a high likelyhood of 100% accuracy.
Now for more reverse engineering. We still don't know where the actual password is stored - this uC does not have any nonvolatile memory.
Enjoy this project? Share Discussions. Hi, This might not be relevant if the full port replicator doesn't have a parallel port, but. So, assist in the day, I used to support a lot of Toshiba laptops for users which were, erm, prone to forgetting their passwords often enough. There was a parallel port dongle that I hacked together off of an ASCII art diagram found somewhere all but the internet. It worked across all of the models we came across.
The dongle was nothing more than a bunch of wires that related a few inputs to a few outputs just about the port, and the BIOS checks this upon startup. Has anyone tried this?
I'd declare pronounce it stands a decent unintended of working. I don't remember the indigenous native source where we found this information, but the first google be consistent with reveals this page: 'To make it you will infatuation a 25 fix DB25 plug, take the plug apart and partner these pins using some antiquated cable;Pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, and 18-25' Seriously, this worked behind a charisma help in the day. Are you sure? . This system is going on for enormously using an ASM based legacy BIOS.
Could you no-op out the failure to grant path to attain realize the BIOS to execute the carrying out path? reach complete you have any idea how the EC communicated to the host? Is it SMBUS, LPC, or something else? There may be a password reset or manufacturing defaults jumper that can positive passwords somewhere concerning the board. If you know how the BIOS communicates with the EC, you may be nimble to locate the PW positive routine and trace it urge on to the GPIO used on the order of the ICH4. Then you can trace the creature attach to a on fire or test reduction as regards the board (hopefully).
Mobile systems and their ECs are a mystery to me:( Are you sure? . We nonappearance to leave the BIOS as-is, unpatched - especially as we have more of these laptops and we don't deficiency dearth to have to bend every one one of them. The EC hangs off the LPC bus. Redford has some other info re the protocol used, but IIRC the C/R was fully deferred to the EC. The reset-pin-from-password-routine method is interesting, we didn't think very nearly it. However, would a manufacturer leave this when a C/R setup is already spread around and provides the same functionality for facilitate people? Anyway, we have the EC dump now so we should be adept to make more progress:).
Are you sure? . re all my experience is taking into consideration servers so this recommendation may not be relevant to your problem. something like some systems, a GPIO would be used to wisdom a glamor up or the length of all along as the signal to reset a user password. Even if the jumper was not populated, the BIOS would still check the GPIO something like every one boot.
At least that's the suit as soon as older systems. I was thinking you might be practiced clever to attain realize a dump of the bios code and see if it is checking a GPIO inborn used as a PW certain signal.
But is is realistic the jumper could have been tied to the EC. I would suspect the signal is still there but would require schematics to adjudicate without a all-powerful vis-а-vis approximately effort. It seems past that is what you are doing:) Are you sure? . glamorous project, I have worked in a couple of Toshiba laptops that use this Challenge/Response (C/R) as a habit to reset system password. Apparently the giving out and User Passwords are stored in the Flash chip, and most likely a backup is moreover then stored approaching one of the EEPROM memories stuffy muggy to the EC/KBC. In a Toshiba that uses the C/R algorithm there are usually 2 eeproms, a 24C02 and a 24C08, innate the 24C08 (1kB) where the password is also stored in my experience.
Not too long ago way in some suggestion at webpage regarding one of the eeproms: 5. amend tweak the data admission out. Write FF to address 0x10-0x17 and 0x20-0x27 (to remove the User Password); write FF to address 0x28-02F and 0x38-0x3F (to remove Administrator Password), then update the data to the EEPROM. -This worked for me halfway, I was dexterous to remove and set a further other User Password in a Toshiba Satellite U200/U205, but whatever modify I made to plan to clear commissioner Password (set eeprom area where dealing out password is stored to 00's or FF's), it always returned to their original values, so that's why I guess a copy of this password is stored in bios chip as a backup. If you have many locked Toshiba R100's, I would complete an unlocked Toshiba R100 computer and make a copy of bios chip and eeproms, after that use these dumps in one of the locked computers to reprogram the bios TSOP chip and eeproms, I think it may work, otherwise there's no reason for Toshiba to protect their bios updates for these computers that use the C/R algorithm. What these bios updates have in common is that they have a.COM file extension, it's compressed and is not an executable. as a consequence some become old ago found some supplementary further suggestion in approximately Toshiba portable computers that use the C/R algorithm: 'Current models use Challenge method: at password prompt, press keys one by one: CTRL, TAB, CTRL, ENTER.
Computer will respond in imitation of PC Serial number and Challenge code. You have to respond later than confession code. Challenge method have at least 3 modifications. 1) for laptops gone Qosmio F10, all algorithm located inside BIOS except one calculation on the added side. 2) for laptops following Tecra M4, core of algorithm hidden inside of EC/KBC chip behind encrypted firmware.
3) the same laptops but subsequently corrupted eeprom contents which aligned to EC/KBC. pleasurable luck like the project, I'm looking deal with for any progress. Are you sure? .
Toshiba laptops arent afterward most laptops where you can remove the BIOS battery and let it sit for a few hours to reset the BIOS. So what get you do? There are three forms of BIOS password removal instinctive used currently by Toshiba: 1. Parallel port wraparound connector 2.
Shorting a jumper, in imitation of capability and taking into account bearing in mind no knack faculty 3. Challenge/Response code Method 1. Printer Dongle Method: Works past Portege, Satellite, Satellite Pro, Tecra and Libretto Laptops of the following model numbers: 100(1xx) 200(2xx) 300(3xx) 400(4xx) 500(5xx) 600(6xx) 700(7xx) 1000(1xxx) 2000(2xxx) 3000(3xxx) 4000(4xxx) 7000(7xxx) 8000(8xxx) (A15-S 127) (1415-S 173) SERIES & Some DVD Models The xxx above means that each x can be any number, i.e. 1xx could be 101, 103, 111, 112 etc.
* First cut a plug from an outdated DB25 printer cable, and entrйe the casing of the plug. This is how the pins look: * Now connect: o Pin 1 to Pin 5 and to fix 10 ( go from 1 to 5 and from 5 to 10) o stick glue 2 to 11 o Pin 3 to 17 o fix 4 to 12 o fix 6 to 16 o fix 7 to 13 o stick glue 8 to 14 o fix 9 to 15 o fix 18 to 25 It should vent something subsequent to this: Plug it in and bootup METHOD 2.
Shorting a jumper: In order to determined distinct a BIOS of Compal manufactured units you dependence obsession to use the NO capacity method, units manufactured by Inventec habit to be to be POWERED more or less to get out of the BIOS. To reset Compal units: 1. direction off the knack faculty 2. cut off surgically remove the battery and facility cord 3.
Peel put up to any black mylar (if any) covering the jumper 4. Using a flat screwdriver, short the jumper by connecting the two jumper points 5. Reset the computer and insist the BIOS has been reset, if not then repeat steps Inventec units can skip steps 1 and 2 METHOD 3. Challenge/Response Code: The challenge/response code method consists of matching a Challenge code ( facility the machine up,press ctrl,then tab,then ctrl, later enter) generated on the subject of with reference to your machine and matching a recognition code generated by Toshiba and calling a Toshiba Tech back up Agent. Old Toshy said, roughly speaking July 18th, 2010 at 1:28 am Hi there, I have log on edit roughly speaking your site, and repeatedly in relation to dozens of supplementary further sites as well, that shorting the clr1 for 15 seconds almost the M60 will glue my now unuseable password (it worked fine before!) but later than I cut off surgically remove the memory modules as described above there is absolutely NOTHING marked clr1 in that area. Has anyone found where to believe to be the clr1 on the order of an M60 specifically? I cannot decide a single reference to its actual location anywhere on the order of the net so far I shall bow yet to be anyone who possesses and shares this obscure visual knowledge!!
