SG500-52 infinite reboot after upgrade

I tried to upgrade my passage to the new version of code and firmware of the boot, but the device is now in an infinite reboot loop, does not respond to the connection of the serial console and will not be reset to the original image when I press and hold the reset button.

How can I get my switch back?

Hi Brendan,

There's not much you can do without access to the switch. Please make sure that when you test the switch is not connected to the network where the cause of the problem is related to network traffic.

You should be able to get the connection console if:

1 speed is fixed at 115 200 baud

2. using the serial cable that was in the package

Kind regards

    My Windows Vista-based computer through an automatic upgrade last week.   After installing the upgrade, I was necessary to reboot the machine to complete the installation of the command.  When the computer restarts, it will show the Microsoft Logo and then arrive at a screen indicating that it finishes the installation.  After 10 seconds, it will reboot the machine and restart the process.  He only stopped when I turned off the machine.  I was able to get to a DOS command prompt and can access the hard drive, the material seems correct.  However, when I try a system recovery, it will say that it does not find a recovery before installing the upgrade.  Any suggestions on what I can do to try to short to reformat the entire hard drive or reinstalling Vista?

  • Problems syncing notes app after upgrading to iOS 10

    Hi all

    I hear a lot of people having the same problem on the web.

    After upgrading my iPhone 6 s more and iPad Pro iPad 9.7 ", kept perfect notes that I saved in the Notes application (like my MBP / iMac too), while on my iPhone, I've known many sync problems and even lost notes and records.

    1. I tried to pass and on the synchronization of Notes in the iOS iCloud preferences, with a reboot between stocks. Nope. No synchronization, and when I turned on sync I lost almost all of the notes previously saved in my iPhone, so I now 15 notes instead of 175. This ONLY happens on my iPhone, while iPad / MBP / iMac yet.

    2 - I tried to create a new folder in my MBP or in my iMac, hoping to "stimulate" a new event to Resync through all my devices. Not for the iPhone, but synchronized on my iPad / MBP / iMac.

    3. today, I made a backup of my iPhone, reinstalled the iOS 10, then restored the backup.

    Nope.

    Any ideas, guys?

    Thank you

    Luca

    EDIT: actually sync problems seems to occur exclusively on the side of the iOS. This also includes the iPad. Fortunately, I didn't have the great idea to disable the synchronization of Notes in iCloud on my iPad, as I did on the iPhone.

    I'd lose certainly all currently stored notes in my iPad too.

  • keyboard language was changed after upgrade to 10.11.5

    After upgrading to El Capitan 10.11.5 I could no longer connect to my MacBook Air using the password. However, after a hard reboot, I could, but the computer will not accept my password, for example, the installation of an application. It would work only to restart the computer. Finally, I noticed that the keyboard language changed to English, which is probably why some characters my password was not entered correctly. Has anyone else had the same problem?

    To make sure that various keyboards are available for the connection, you can go to the prefs system/users and groups/connection options and tick the box to display the menu before when connecting.

  • Satellite L300D BSOD after upgrade to Windows 7

    I got this laptop (Satellite L300D) for a little more than a year with windows vista (32-bit) running and there were no problems. However, I've recently upgraded to Windows 7 (x 64) and became the problems since the first reboot.

    On the first reboot after installing windows 7, the computer off just after the "Starting Windows" screen Turn on again took me to the repair of the system where he performed a system restore and I was able to start successfully even once. I thought that the problem had something to do with the automatic updates, so I disabled the and tried to restart to see if the problem has been corrected. This time, after the "Starting Windows" screen I got a BSOD of unrecoverable system error. After several attempts to reboot and multiple attempts to repair system (which usually says she didn't) it started correctly again.

    This problem has been going for about 3 weeks now and it is quite irritating. The results of the system of compensation for claims that a "Boot critical file is corrupt", but it starts eventually after several attempts to start. He also has a habit of turning at random during the race (it happens about once or twice a day). So from now on, whenever I chaque fois que je tente tries to start my computer it shuts down after the start screen or give the BSOD and restarts and the only way to make it work seems to be to keep trying to start and hope for a successful boot of the system upward (this happens finally after a few failed attempts).

    I did some research on this and came to [this | 1251 http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?modelFilter=L300D-ST3501&rpn=PSLC8U&category=&selCategory=3&moid=222 & os = & ct = DL & selFamily = 1073768663] page. I think that's exactly what my problem is (need to update the BIOS), but if I understand correctly installing windows to do this only for 2000/xp/vista and I am unable to use the second option to boot from the disc as I get the BSOD before he gets to that point. I should try the windows install option although I am running windows 7 or is there another way to update the BIOS? Or I'm off completely and the problem is with something else?

    I wasn't sure what information I would like to add to this post so if need more information please let me know.

    Thanks in advance

    Edit: Oops, just realized the page I linked is not link to exactly what I had opened. I do not speak of 'critical BIOS updates for Windows 7 64-bit' under 'support form '.

    Hello

    First of all, it would be interesting to know what code BSOD, you get exactly. Can you post this information useful? Normally, on the Microsoft Knowledge Base, you can find additional information about most of the BSOD codes and so you can start to solve this problem.

    BSODS are often associated with drivers or RAM/HDD. The latter, you can check with special diagnostic tools, Memtest86 for RAM and Drive Fitness Test for the HARD drive. These two tools are free and you can find it using Google. You can download an iso image of them to create a bootable media where you can start the test.

    Regarding your update to the BIOS: I put t know what L300D you have exactly, but according to the Toshiba site it shows an update of the BIOS also for Windows 7 64-bit. You can try to install it.

  • Second monitor is not detected after upgrade to Windows 10

    After you have installed Windows 10 upgrade Windows 7, my second monitor is no longer functional. The computer is an HP Touch Smart 610-1065qd. I connect on the second monitor through a USB 2.0 Port Replicator 2005pr HP. The Replicator appears as a drive when you look at this PC and an arbitrator in him like HP USB DOCK, as it did in Windows 7. The Replicator seems to work, I can't access the SSD on the device and use a wireless mouse. The receiver is connected to the port replicator. The second monitor, also connected to the Replicator, as it was before the upgrade. Now the system is unable to detect this monitor. The MANAGER of peripheral DEVICES, MONITORS, indicates there is a monitor Active, listed as "PnP monitor" generic Device Manager displays a second monitor as a hidden device. Identified as a "generic PnP monitor' and the State of the device is"currently, this hardware device is not connected to the computer. (Code 45) ». In Windows 7, I don't remember the second monitor listing. USB and the DISPLAY NETWORK DEVICES, the entry is USB PORTS port REPLICATOR 2.0 HP 2005pr. Under GRAPHICS cards, there are two lists. The first is an adapter named "AMD Mobility Radeon HD 5570". This corresponds to my video card. The second adapter named "glance speed Boost. I believe that Ancestry.com can installed this. "This device is working properly" is the condition for both cards. I manually checked new drivers for all components. There is no effect. Then, I went to HP and downloaded the most recent Setup to monitor. I then tried to load the drivers and monitoring software. I also loaded the screen in compatibility mode, then in compatibility mode for Windows XP SP3, then compatibility for Windows 7 and finely mode as a regulator. As a result, I tried the same process with the original disc. After each test, I rebooted the system. Still unable to detect the second monitor, nothing in Device Manager and unable to detect a new monitor on screen. I attempt to change the Projection. He also, had no effect on the display. Then, I deleted graphics cards. First of all, the adapter "AMD Mobility Radeon HD 5570", which corresponds to my video card. Second, the "Speed Boost glance. This also, don't give not any what on second monitor display. Even if it is visible only when show it hidden devices is checked. Any suggestions will be appreciated.

    I finely found a fix for the problem to my question; Second monitor, not detected after upgrade to Windows 10. Not the one I was hoping. It turns out that the fault was with the HP 2005pr USB 2.0 Port Replicator. It seems that the driver may be at fault. After more than a month of waiting, I decided to replace the duplicator. I decided to buy a Port adapter to replace the duplicator. What is much less expensive experiment and see if it was infecting the duplicator. It turned out that my second monitor is back and healthy. I decided to continue to use the port adapter and buy a USB Hub to replace this part of the duplicator. I no longer use the HD Audio output, after replacing the old speakers with Bose USB speakers some time ago. I thank everyone for help.
