    Hello

    The following steps can help (try again after each):

    • On your iPhone, in the application of the watch, go to: Watch My > general > use > software update - remove any file update, if one is displayed.
    • Delete all profiles beta (on your iPhone and/or the watch), then restart both devices (this applies only if you have already participated in a program of Apple Beta software).
  • My googlemail is blocked due to a forgotten password, but google for the recovery procedure continues to send me round in circles.

    My frozen Googlemail account a few days ago, and I had to use the procedure of recovery to thaw, which included a series of new passwords, provided by Google, which I was told that I would not need to memorize or note down. After a few hours of work successfully, the program froze again and so I am unable to receive or forward all e-mail messages. Google asks me to use the procedure "forgotten password", but I don't know what password is the system, and I continue to be sent in a circle to the same pages.
    I would be grateful for any positive suggestions and thank you in advance.

  • How to fix the error, "the procedure entry point PK11_PubDerive could not be found in the dynamic link library nss3.dll

    I use windows 7 and Firefox 39.0. Recently, when I open Firefox it gives this error, 'the entrance of procedure point PK11_PubDerive could not be located in the dynamic link library nss3.dll'. I click on the OK button, and then Firefox load without any other side effects. But this becomes quite annoying and I would not get an error message to me. I tried to uninstall Firefox (all the same when I search for it, nothing comes up) and re-install. But the message is still there. I'm lost for what to do to get rid of him. Any help would be great!

    Thank you!

  • Equium A100-147: I get an error during the recovery procedure

    Hi again,

    I had trouble with my equium a100-147.
    I tried a restore, but the disc is scratched so I phoned in ESL and it snet me a new recovery image.

    I tried the new recovery disk and am now errors when I boot the disk.

    error is

    "internal error crc file: \WINDOWS\$NtUninstallKB895200$\msdtctm.dl.

    any suggestions are welcome. get really annoyed with my machine as my warranty expired only one month

    Thank you

    Hmm... I studied a bit and it looks a bit like a malfunction of the partition.
    It would be desirable to boot from the original CD of Microsoft XP and to start the repair console.
    Then you could try these various commands which help to repair the boot manager, repair errors, locate bad sectors and recover readable information.

    -fixboot
    -fixmbr
    -bootcfg /rebuild
    -chkdsk /r

    If this does not help, you should erase the entire partitions and must format the HARD drive in NTFS file system. Then access the BIOS and set it to the default value.
    Once this procedure tries to start again on the new recovery CD!

    Good bye

    Do a clean reinstall.

    Download a new copy of Firefox and save the file to the desktop.

    • Uninstall your current version of Firefox.
    • Do not remove the data of a personal nature when you uninstall the current version.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.

    Your bookmarks and other profile data is stored in the Firefox profile folder and will not be affected by a relocation, but make sure that you do not select delete data of a personal nature if you uninstall Firefox.

  • Satellite A100 system goes to a black screen after the recovery procedure

    I tried running the recovery CD, I received on my cell phone. the process perfectly, (I have only one CD, I don't know if I need a second). At the end of the process, I have the option to insert the second CD, or jump.
    Because I don't have that one CD I have support on ignore.

    I tells me that the installation is complete and I can restart my system.
    Then I removed the disk and I tried to reboot the system. The system goes to a black screen (on which he indicates that Microsoft load) and then crashes. That was the problem I was facing before recovery.

    Basically, the recovery process has not worked. I don't think I did something very wrong, unless I need a second CD. What could be the problem?

    Help me please!

    Hello

    The A100 is one of the new series of laptops and AFAIK the image of Toshiba was placed only on a CD (DVD) recovery.
    I think that the message and the possibility to insert the second CDconfuses a little.

    In my opinion the black screen and freeze has nothing to do with the recovery procedure and the new installation if Windows OS.
    Due to the fact that this problem has occurred until you have installed the OS from the recovery CD, I assume that there must be something wrong with the hardware.

    But it s very interesting to know if the same problem appears after the new installation of Windows from the original CD of Microsoft.

    It's worth a try.

  • Is there an automatic procedure to retrieve all the drivers on the Satellite U200?

    I have re-installed XP on my Satellite U200 and lost all drivers and settings. Is there an automatic procedure to retrieve all the? I'm a bit mazed by 52 varieties of the drivers available on the support web site.

    Thank you.

    Alexey.

    You are going to use the Toshiba Recovery CD or will allow you to install all the drivers manually.
    I guess the recovery with XP CD is not available for this laptop and therefore only the manually installation is possible

  • P20: Can I recover the data after the recovery procedure?

    Hello
    I have a toshiba P20, when I buy, I made 2 partitions, C program and the BONES and F to my personal data.

    I use the restore tools toshiba to restore my windows XP OS, but the restore tools has also reset my partition table and I don't know if I can restore my personal data.

    Everything is done in one step and I saw no warning to say that my partition table will be reset?

    It's just a fdisk or a format really has been done.

    Can I use a tools for restore my partition to lose data?

    I hope that there is an acceptable solution to this problem and in a near future, I'll buy an external HD to perform the backup.

    Hello Alex

    If you want to preinstall the device with the recovery media, you can do this in two different ways:
    -standard mode will be formatted the whole HARD disk and after the procedure of recovery on the HARD drive is just a single partition.
    -expert mode using this mode, you can create partitions if the HARD disk has only one, and you will be able to install the OS on the first partition (the other guy)

    Of course, you did using the standard mode and now the whole HARD disk is formatted. I'm not 100% sure, but in this case only fast format is done before the beginning of the procedure of the facilities. Try to find (Google) if there is a tool that can help you verify if all the data is gone. Using recovery media there is no way to do it.

    Drive external HARD is the right solution for the data backup.
