DUe to various issues with the printer including inability to do remote update (connectivity problems) and failed print jobs due to incorrect default tray selection - I have decided to upgrade the firmware to the latest available version 68.67.91. The instructions said to install bridge version 68.59.1 first. I checked the existing version using web interface and it was showing 68.59.1, so I started the upgrade to 68.67.91 via Web Interface. AFter the upgrade started, it was stuck at 12% for some time, then immediately moved to 75%, stuck again then ended up with the message "write error 041-500" on the red screen. I waited and nothing else happened within one hour. Then I tried to reboot the printer and now it comes to the blank screen instead of control panel, and I am unable to connect to it via Web Interface. ALso, connection via USB port no longer works as well. I tried to restart the printer, and one or two times it said "checking file system" but would get stuck at that message. I also noticed that holding power button and home button at the same time while trying to turn on the printer brings it to a "special boot menu" offering "HDD initialize mode" and "Storage device initialize mode" but one of the modes does nothing and second mode shows "file system checking" screen which does not do anything else - even overnight there is no change to the screen. Can Xerox post instructions what have to be done in this case?
Apparently this unit has to be updated through TFTP.. annoying, but ok. I fired up the TFTP server, let the switch acquire the correct firmware file. The switch reboots.. and... it came back at the default IP (192.168.0.239).
The webserver presents a simple page with a menu "Firmware Upgrade" and "Reboot". Under "Firmware Upgrade" it shows two boxes "TFTP Server IP address" and "Image File Name". So it seems this is a boatloader management page to recover a failed firmware.
So I fire up the TFTP server again; result: "Firmware is upgraded successfully. Please wait for the switch to finish rebooting with new firmware."
The switch reboots... and again; the bootlader page on the default IP. What the heck is going on?
I've tried the older firmware version (1.4.0.6), I've tried different TFTP servers. Nothing seems to work.
Apparently the ProSafe Utility uses a different method of delivering the firmware to the switch because the TFTP server port was still in use on my PC because of the TFTP server which was still running.
If ever upgrading the firmware using TFTP doesn't work for you, kindly try to upgrade the firmware using the ProSAFE Plus Configuration Utility. Kindly follow the steps on pages 65-66 of the ProSAFE Gigabit Web Managed (Plus) Switches user manual here. You may download the latest ProSAFE Plus Configuration Utility v2.3.25 here.
Then open the explorer, and while pressing the S1 switch on the USB2ANY connect the USB to your computer, it should prompt you to update the firmware and then follow the instructions of the application to complete.
Unfortunately it looks like the USB2ANY is indeed bricked and has memory problem, it probably happens due to an incorrect firmware update. Please get another USB2ANY and use the Explorer and instructions above to upgrade the firmware.
The TICHARGERSGUI -CHARGER-GUI would also give the option on connect to update the firmware if it detects an older version is loaded on your USB2ANY.
It was not detected in TI-CHARGER the first time I plug it in. I thought it might be a firmware issue. I tried to upgrade it following carefully the instructions provided and it got bricked in the first attempt.
The USB2ANY Explorer is the software we recommend to restore the device to a usable state. It looks you had used two different software tools and both of them are reporting a memory fault or problem in the device. I do not know how the usb2any got damage, but going with the information provided by you it looks like the device is bricked. I support BQ25180 devices, and the usb2any is one of the tools we recommend users to getting starting with the device, but normally the device works out of the box and as long as you used the recommended tools it should upgrade the firmware and works with the GUI. Keep in mind the BQ25180 is I2C compatible, so it'll work with any I2C host.
This is nothing to be alarmed about, but you should at least be aware that you are not running a final release version, and from our experience on OctoPrint's support channels we had to find that a lot of people aren't, hence the introduction of this short info. Running a development build means that more bugs might arise that also negatively influence the communication with OctoPrint and that you should be on the lookout for any kind of announcements or warnings both on OctoPrint's side and the firmware's side regarding current problems with the development versions.
If you are a more advanced user who regularly builds and flashes their own firmware or maybe even participates in ongoing development, first of all, good on you , and second of all, you can safely get rid of this info once and for all by clicking the conveniently provided link that says Disable firmware checks of severity "info" right below it.
If you are a new user, have no idea what all this means and were directed to flash this firmware by a third party, please be advised that you are running a version that is still being in active development, might be more or less stable depending on what specific build you flashed. If you do not plan or are not able to flash a stable build, you should at least make sure to update your firmware to the latest development builds regularly so that you get bug fixes.
Last night my RAX43 did some sort of auto-update/factory reset, which put my SSIDs back to factory defaults. I fixed that, reconnected wifi, but now the problem is the wifi signal keeps cutting out every few minutes. This has never happened before and nothing I can do fixes it. I'm on firmware V1.0.12.120_2.0.83.
Same exact thing happened to me overnight on a RAX43 router. I woke up to find all my network names were gone and had reset to factory default. I also noticed it auto-updated my firmware overnight. This has never happened before. More concering is, once I restored my SSIDs and got everything re-connected, wi-fi is now very flakey. The router keeps dropping the wifi signal. No idea what's going on.
My RAX43 did a factory reset last night because it auto updated to new firmware, which then screwed everything up. I had to revert to older firmware, and then disable Autoupdate so this doesn't happen again.
There, any device for which a new firmware version is available will show a green Update button. Press that button to initiate the update. N.B. the location for this facility has move to the bottom of the Device List, as per the earlier video.
In most situations the system will already have a firmware file available; no need to upload anything yourself. Sometimes however it is necessary to upload a file from your computer; and this chapter explains how that's done.
BlackTech has targeted and exploited various brands and versions of router devices. TTPs against routers enable the actors to conceal configuration changes, hide commands, and disable logging while BlackTech actors conduct operations. BlackTech actors have compromised several Cisco routers using variations of a customized firmware backdoor [T1542.004]. The backdoor functionality is enabled and disabled through specially crafted TCP or UDP packets [T1205]. This TTP is not solely limited to Cisco routers, and similar techniques could be used to enable backdoors in other network equipment.
In some cases, BlackTech actors replace the firmware for certain Cisco IOS-based routers with malicious firmware. Although BlackTech actors already had elevated privileges [TA0004] on the router to replace the firmware via command-line execution, the malicious firmware is used to establish persistent backdoor access [TA0003] and obfuscate future malicious activity. The modified firmware uses a built-in SSH backdoor [T1556.004], allowing BlackTech actors to maintain access to the compromised router without BlackTech connections being logged [T1562.003]. BlackTech actors bypass the router's built-in security features by first installing older legitimate firmware [T1601.002] that they then modify in memory to allow the installation of a modified, unsigned bootloader and modified, unsigned firmware [T1601.001]. The modified bootloader enables the modified firmware to continue evading detection [T1553.006], however, it is not always necessary.
To enable the backdoor functions, the firmware checks for incoming trigger packets and enables or disables the backdoor functionality. When the backdoor is enabled, associated logging functions on the router are bypassed. The source IP address is stored and used to bypass ACL handling for matching packets. The SSH backdoor includes a special username that does not require additional authentication.
In order to detect and mitigate this BlackTech malicious activity, the authoring agencies strongly recommend the following detection and mitigation techniques. It would be trivial for the BlackTech actors to modify values in their backdoors that would render specific signatures of this router backdoor obsolete. For more robust detection, network defenders should monitor network devices for unauthorized downloads of bootloaders and firmware images and reboots. Network defenders should also monitor for unusual traffic destined to the router, including SSH.
Open the PlutoSDR mass storage device or M2K mass storage device. This will have a file called info.html. Double clicking on this file should open it in your favourite browser, clicking on the firmware tag in the top should take you down to a section that looks like this:
