  • iPhone stuck in DFU and PC mode does not recognize device after installation of iOS 9.3.2 failure

    So today, I decided to upgrade my firmware to the latest 9.3.2 via iTunes 9.2. Everything was fine. Both PC and iTunes recognized my phone and the upgrade process was fine, until suddenly I'm met by a mistake to say that the update failed, which was then followed by an immediate blue screen of death, with the error pointing to 'asmtxhci.sys', the XHCI Host Controller Driver of ASMedia Technology Inc.. My phone is then stuck in DFU, and my PC mode and iTunes refuses to recognize my device. I checked Device Manager and noticed this strange spectacle:

    It lists somehow my camera as two separate. I tried to install the drivers manually from "C:\Program Files\Common Apple Mobile Device Support\Drivers". I managed to install the drivers for the DFU mode (but he didn't) I met for the first device, but when I tried for the second device by mistake 10 "device could not start" or something like that.

    I don't know how to proceed from here. I tried so many stuff, read so many other messages, but I have not seen anyone with my problems, that's why I went here. I'm half - panic right now...

    This sounds like a rather nasty problem - maybe a conflict with ASMedia USB and Apple Mobile Device Driver.  If you do a Google search on "asmtxhci.sys" you may reports of this cause the blue screen of death (BSOD).  There are a few patches recommended, but I'm not going to suggest anything as I'm not familiar with any of them and they could cause various other problems (even worse).  Good luck!!!

  • iPhone battery 6 draining on the home screen and locking

    I've read other posts on the drain of the battery on the iphone but that you did not find an answer that reflects my situation.

    Relates to the iphone 6, ios 9.3.1 64 GB,.

    I took my phone this morning and pressed the home button to check the remaining capacity before getting ready for the day.  It is 79%.

    I ask without opening any application or even unlock.  As usual, the screen goes black after a few seconds.  I go back an hour and a half later, and now it's 23%.  So I check the battery use it it shows as home and lock screen used 97% of the power of the battery since my last load.

    Why the drain?  It doesn't drain as quickly when I watch a video and it was just the home button to check the remaining power.

    The percentage shown is not since the last charge. It's usage in the last 24 hours. It could have been 5 counts at the moment.

  • I'm stuck on siri and I can't get out

    I'm stuck on siri and I can't

    What do you mean you're stuck? By pressing the home button should turn off Siri and return to the home page. If it won't work, then go ahead a reset of the device. This will not affect your content. Hold down the home and sleep/wake together until you see the Apple logo and then release. The unit should restart.

  • I am not able to change the video quality for you tube. There are only two options 360 and Auto. Please help me.

    Hi I am experiencing strange problem for 15 to 20 days and I am not able to change the video quality for you tube. There are only two options 360 and Auto. Help me please if you can because I have a slow internet connection and I want to play video at 240, as it was before. Thanks in advance for your help.

    Could check you whether YouTube is to serve its HTML5 player or the player based on Flash? If you right click on the drive, short a context menu should appear. If the full Firefox context menu is displayed, press and release the ALT key to erase that. The last line of the menu short usually indicates which player he is.

    I'll assume HTML5 because...

    On Windows 7, Firefox should show a wide range of formats in the HTML5 player. However, if some of the features of media are disabled, preventing video MP4 decoding, then YouTube offers only 360 p (with WebM coding).

    If you have intentionally disabled Media Foundation and/or DirectShow in topic: config, then perhaps you would prefer to use the YouTube Flash Player? There are a few Add-ons that can force YouTube to serve you a Flash drive. Either of them will do, you don't need both:

  • Cannot automatically download new messages and auto answer with out-of-Office message must manually check for new messages, so he can do

    I use Mozilla Thunderbird 31.3.0. I know how to create a message filter, to implement a response message automatic, but impossible to get Mozilla to automatically download new message and auto reply with the message in the filter, unless I have manually check for new messages, this is the only way to make it work. I looked online and can't seem to find an answer to that particular question. According to everything I found, I have the right boxes checked in the server settings: automatically check for new messages at startup, check new messages, check for new messages every x amount of minutes. It's one thing to have leave my computer and open Thunderbird for this works, but having to manually check for new messages get the AutoReply to work defeats the whole purpose of having an automatic response, because I use them for vacations, holidays, etc. I wondered if there are security settings that cause this problem, but if so, I don't know what changes to do to them. Thanks in advance for any help. It drives me crazy.

    I find it a little odd that Thunderbird does not mail on the calendar, you may have an add-on or antivirus program that prevents this.

    Now shift while you start Thunderbird will begin with disabled modules to check if the messages are automatically.

    By air is to the right, use the autoresponder Verizons. This link might help with this http://www.verizon.com/support/residential/internet/highspeed/account+tools/email+tools/questionsone/85621.htm#
    You say that not having is not such a context in Thunderbird is something that needs fixing. This idea comes across because Outlook has such an option. what most people don't know of it only works with Exchange server. There is no "vacation response" in the specifications of the mail server so every server implements differently.

    As all cars have a radiator, you can't take any radiator, and simply put, they are subtly different even if they perform the same purpose. Goes same for stakeholders of vacation, they perform the same function, but they differ between brands of e-mail server software.

    Thunderbird leaves the server end to expose the feature, because they are really the only ones who understand what they were doing. Outlook exposes the option and especially greys out.

  • touch screen works is not to a few areas and typing randomly

    The touchscreen does not work in specific areas of the screen. and also it behaves erratically, opening, closing and switching applications and typing randomly on its own... sometimes the home button also stops working.

    The problem started with "ghost typing" and automatic switching of applications. and recently to the touch in some places on the screen also stopped working...

    I do not have a centered around Apple care, so I thought to get certain points of view on this problem before relying completely on the local repair store guy...

    You have coverage on the iPad that can interfere with the screen?  I've seen other shadow report type and it turns out being the hardware issues, but try some basic troubleshooting steps. Close all applications and the strength to restart the device first.

    Close all applications. Press the Home button twice quickly. You will see small glimpses of your applications recently used. Drag to the left to find the application you want to close. Swipe up on the preview of the application to close.

    Now restart of strength. To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.

    If this difference, try this. Reset all the settings. You won't lose any data, but all the parameters of the device will have to be entered again in the settings app. This includes the WiFi password. Settings > general > reset > reset all settings.
