    Netgear router WGT624 Ver.4 flash memory file

    Hi again,
    Does anybody has this router and wants to help?
    I need the flash memory MX25L3205 binary file to reprogram my breaked router.
    I know it's too much but, who knows? Maybe someone has it and can help me.
    TIA

    did you relpace the chip, or just corrupt the flash?

    becaue if you corrupted the flash you can recover it with a serial interface on the board.

        I have replaced the chip by dissoldering it and reprogramed A BLANK NEW one with the webflash dd-wrt firmware but no luck. I need the original binary readen with a programmer device. I have already accept the fact that this machine is breaked but hope dies last as they said...!

          you need to program the start of the chip with the bootloader called CFE
          i dont have it for that router so you need to search.

          question:
          did you pull a 2meg flash to replace it with a 4meg?
          if you did then you can copy the CFE from the old one, but you must make changes with a hex editor to show the new flash size.

            No, i have replaced it with the same flash memmory. My mistake is that i have already reprogramed unsuccesfully it's own flash before i save the binary for backup reasons.

              You probably need to use JTAG to reprogram the chip.
              Here's some starting info about that:

              http://www.dd-wrt.com/wiki/index.php/JTAG

              I've done it to a Belkin router, finding the JTAG connection points on the ckt board is the first hurdle then you need a "wiggler" cable to connect the JTAG connections to the LPT port on a PC, then use a tftp program to shoot the code to the chip from the PC.

                I have looked in the link you gave me but there are some "directives" i should not overcome.
                As i noticed the total cost for having access to this jtag system will totaly be about 25$ (device +donation) which i dont have them.
                The second thing is that i need the cfe for my WGT624 V4 router and i can't find it so far.
                In conclusion if someone has this cfe file for this router, or even better the bin from original flash chip, please send a post.
                TIA

                  Re: Netgear router WGT624 Ver.4 flash memory file

                  i have a CFE for wgr614 if it has the same ram.

                  the jtag software is free on sourceforge btw.
                  http://tjtag.sourceforge.net/

                  if you never want to use the factory firmware you can use REDBOOT instead of CFE.
                  search about it at the DD-wrt forums.

                    Re: Netgear router WGT624 Ver.4 flash memory file

                    stj@ Thank you for helping me.
                    The only thing i want is to unbrick this device, no matter what kernel or firmware it will have.
                    About JTAG, my device has only 6 pins for serial port connection. No JTAG connector though. If anyone knows more about it, please post here.
                    As i can guess, the only possible sollution must be a simple binary file which i can transfer to my dessoldered flash memmory chip by a programmer and cross my fingers...

                      Re: Netgear router WGT624 Ver.4 dump flash file

                      I wonder if anyone has a dump flash binary file to use it with my usb programmer and reprogramming my flash chip. Also please give some instuctions about config fuses.
                      TIA

                        Concerning JTAG, it can be an arduous process but it does not have to cost much if you make you own cable from an old parallel printer cable and a few resistors. A lot of routers do not have JTAG pins on the board but do have solder points to make JTAG connections to. The hard part is finding where the solder points are on the board.

                          Unable to verify IC or write/erase/flash BIOS file to XMC QH128AHIG SPI chip using NeoProgrammer/AsProgrammer
                          by testaccgta
                          Hi, everyone!

                          I've recently acquired two brand new SPI chips to replace the one currently in my Acer A514-54G laptop MB (FH5AT LA-K092P). The reason why I'm replacing the current SPI chip is because I had some difficulties with a third-party IT assistant who pretty much lacked the soldering skills and ended up destroying the current SPI chip soldered to my MB from factory.

                          I've decided to do this on my own because I spent the past month or so learning some soldering skills and BIOS modding through Badcaps and WinRaid forums, hence the attempt. I've also chosen to buy...

                          UPNP, "Standards" and hardware that implements it
                          by EasyGoing1
                          I've been writing a program in Java that is really just a robust front end for the use of GitHiub Gists, providing a nice interface for developers to organize, maintain and access code snippets that we tend to need from time to time in our different projects.

                          One of the features of the program is the ability for people to share their Gists with others who use the program over a LAN or over the Internet. The program just basically serializes a Java class and encrypts it then wraps it into a UDP datastream and sends it over to another user.

                          So I decided to implement UPNP...

                          by ekozeko333
                          Hi all,
                          I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
                          🔥 The Problem Started After Suspected ESD/PD Fault
                          I experienced a power issue or ESD event through a USB-C charger
                          After that, the NX20P5090 power switch was visibly burned and was replaced
                          Now the PD controller always negotiates 5V @ 2A, even with known-good chargers

                          Nikon D800 camera - flash don’t work and capacitor don’t charge
                          by corrize
                          Hello, I'm stuck in troubleshooting…
                          The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.

                          In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
                          When I press the flash button, it's detected by the system, flash icon appear on LDC display....
