How to downgrade firmware of Cisco Switch C3850 24T S - cisco

I am looking for a way to downgrade my Cisco Switch's firmware from Cisco IOS XE 16.06.04 to 15.0. Is there a way to do that? I read posts that firmware downgrade can be done by TFTP server but I cannot find the correct image online. I cannot find any downloads from CISCO official website and it seems they intended to do this as they no longer support 15.0 IOS and force users to upfrade to 16.X. Despite that, I need to downgrade to 15.0 as my client server's switches all use 15.0 version and I need to match them.

You might check the Switch's flash just to know if the old version is still there running the command
show flash:
or
dir flash:
if it is still there, you might continue with downgrade process.

Citrix receiver 4.11 Windows 10 64 bit repeated download prompt

I've just downloaded latest Citrix Receiver onto my Windows 10 64 bit system.
Everything works ok with one exception.
Every time I launch the calling browser, whether Chrome, Edge or Firefox, I'm prompted to download latest version of Citrix Receiver.
Does not seem to be an option to avoid this, so have to do and when the download executes it reports latest version already loaded and I can then get onto my remote site.
Any ideas?
Thanks
Perry
maybe you need to run Citrix install as admin, so it can write to the registry or where it is that the browser is checking

Firefox OS: Back up and restore user data

I am trying to upgrade my ZTE Open from FFOS 1.1 to 1.2. According to the instructions:
Note that those steps will erase your personal data, so be sure to make a (backup) first.
However, the backup link doesn't really seem to be talking about backing up user data between versions, and I'm not at all sure how I would use those backed up files to restore my data after a successful upgrade.
Does anyone have experience with manual backup/restore between different versions of Firefox OS?
I am not sure how version safe this is, but I was able to restore my apps and contacts when upgrading my keon from 1.2 to 1.3 using the following adb commands:
adb pull /data ./data
adb push ./data /data

Windows phone 8.0 error 0x89371B01 when trying to deploy app

I cant find information on this error anywhere. I am connecting to a brand new lumia icon (AKA lumia 929). Dev account is registered. I have attempted:
reinstalling windows phone SDK
restarting phone
restarting computer
ensured the app runs on the emulators properly. the only required capability of this app is network. Capabilities have not been changed from the defaults since the project was created. none of the manifest xml files have been touched.
ensured phone software version is up to date
ensured apphub account is valid and active
ensured the windows phone developer registration tool worked, unregistered and re-registered the phone to make sure
restarting the "ip over usb" windows service thingy
changing the platform built target to ARM or AnyCpu (no difference, same error)
tried alternate deployment methods such as windows phone power tools (the xap deploy) and I get the same error when trying to connect (so I know it's not an issue with visual studio, nor is it an issue with the app code)
I can successfully deploy separate code to a separate WP7 device (so I know it's not an issue with the computer)
tried multiple usb ports
tried two separate laptops
tried visual studio 2013 and 2012
The behavior is this:
Connect the phone via usb and unlock it
Attempt to connect to phone via windows phone power tools OR deploy an app via visual studio
System hangs for about 90 seconds and seems to time out
Error appears
I am able to view the phone contents, name it and explore it on my laptop, but when it comes time to deploy something I am stuck.
Error message is simply: 0x89371B01
What does that mean? Has anyone else run into this?
Have you checked the device drivers on your Windows 8.1 machine? It could be a driver issue with your USB drivers on the computer.
I have also found that, once you get it connected, going into the Device Manager and deleting the device from there and forcing it to reload has helped me in the past.
Out of curiosity, try running "sfc /scannow" at a command prompt on the PC. It may require admin elevation. I've seen some bizarre behaviors due to dll problems in sxs in win 8.1, wondering if this could be caused by that kind of thing.
Couple of things to try:
Have you installed the GDR3 Emulators and tried running it on the 1080p emulator? It looks like the 929 is a 1920x1080 phone and will have the latest the latest updates installed. First place to check.
Based on this feedback in another stackoverflow question it looks like someone was having a similar issue and disabling Hyper-V resolved it for him. If you disable Hyper-V and it works, try re-enabling it and see if you still have the issue.
jmshapland had the correct answer for me, with the same issue. Disabling Hyper-V did the trick! No thanks to microsoft phone dev center forum posting on the issue..
http://social.msdn.microsoft.com/Forums/wpapps/en-US/24bd3e48-e7b4-4d00-8d69-193f49989ce0/0x89731b01-error-during-deploy-to-device?forum=wpdevelop
Looks like I'll be disabling Hyper-V to test on my device, and re-enabling to work in emulator mode:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
and
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
OK I was able to come up with a repeatable solution for the issue. Im HOPING that by posting this I dont tempt fate and have the phone not work again!
Here are the steps I did to resolve it (not sure if all of them are necessary):
On phone, disable wireless
Connect phone to laptop
Open device manager and click to show ALL HIDDEN DEVICES (including hidden devices is important)
Uninstall ALL phone-related devices (one in portable devices, several in USB
devices) anything that mentions lumia must go
Disconnect/reboot phone
Reboot laptop (there seems to be a process keeping the port open)
I had connectivity, then I lost it, then I re-gained it using these steps and it seems to be reliable for me (so far)

Remote Control WinCE 6.0 device from Windows 7

I am trying to find out a tool to remote control a Motorola MC3190 device running Windows CE 6.0 from a Windows 7 machine.
I have already used Mymobiler with Intermec CN3 device so I tried the answers in this question but I am unable to get it to work.
I have tried both remote.exe.40 and remote.exe.50 in the Mymobiler folder
Using Task Manager on CodeProject mentioned in a question on superuser it seems remote.exe completes execution very quickly (or is crashing silently).
My Start/Programs menu has a MyMobiler entry, so somewhere along the line something seems to have got installed
But when I run Mymobiler on desktop it cannot connect, its icon in system trey remains gray and on mouse hover says Not Connected/
In Proof MyMobiler works for WinCE video the processor is ARM920T-PXA270M while my device has a Marevell, PXA32X-P (link to image) processor could that be the reason?
I have also tried ActiveSync Remote Display from Windows Mobile Developer Power Toys. It installs but at start up it shows an error box with message "The OS or CPU of this device is unknown to this application"
How do I get MyMobiler to work with Motorola MC3190 device running Windows CE 6.0?
Is there any other tool, preferably free, to remote control this device?
EDIT: I came across EveryWAN and found an installer. It works out of box, but it is not available for commercial use and the web-site seems defunct.
PS: I realize the tags are not accurate but I wanted to use something that will attract attention of experts in these similar tags.
I want to clarify one answer to the above which is correct. When using the Microsoft PowerToy activesync remote display, there must be an application on both sides - host(the phone) and remote (the pc). The same is true for MyMobiler.
Install the powertoy on the pc.
For the original Poster: This is what your error message means:
In the case of Activecync Remote display, for newer devices (anything above ARM4 cpus - which means, 2008 and up, or over 200mhz cpus - as a very general guide), the display software cannot detect what type of device you have (it's too new, and not in the list).
For the motorola mc3190, your cpu is arm5 compatible,
and should work with software that has arm4 compliant components. ARD does have arm 4 options. see here...
To Fix it:
You must use file explorer on your pc, and navigate into the application folder: c\Programs...\Windows Mobile Developer...\ActiveSync...\Devices\wce400\armv4t and copy the two files.
While still on the pc, you must then navigate to the Windows folder of the device (with activesync running, OR the phone configured to be seen as a hard disc), use explorer on the PC to navigate to the device.
Vaguely, it will look like this:
Explorer. > Device (such as HTC Phone:)
Or, X:\ , where x is a drive letter.
The first subfolder your select should be Windows. Paste the two files there.
The two files are now copied onto the phone.
At that point, you must, using the phone, load it's file explorer and navigate to that Windows folder on internal memory and manually run cerdisp2.exe that you have now copied there.
With activesync running, and the phone connected to the pc,
You can now run the powertoy active remote display on the pc, and it will communicate with the exe that is running on the phone.
ActiveSync on Xp, or Windows Mobile Device Center on Windows Vista/7/8 must be running for this all to work.
Alternately, the app allows for a networking ip connection instead of activesync, but I have not used it.
When you are done using this app, you must run the kill.exe on the phone, in the windows folder (the second file you copied), to unload the dll that is running.
I can verify this setup works on Xp, Win7 and Win8 - with an Xscale ARM11 528mhz cpu phone.
For MyMobiler, visit their site and get the newest version.
It WILL fix connections that fail, if you have the older version. It's free. They don't support it anymore.
My Mobiler must have activesync running and showing the device connected.
My Mobiler is vastly superior to ActiveSyncRD.
* It will automatically install the pc side app, and push the remote app to the phone, via activesync.
*Further, when activesync is running and anytime you connect the phone, the MyMobiler app will autoload on the phone as well.
That way, whenever you run MyMobiler on the desktop, it will connect to the phone and load right up.
*My Mobiler allows full resolution display, while ARD is limited to 320x400 or similar. 640x800 looks much better.
*MyMobiler also allows full mouse gesture sends, and copy and paste. ARD offers very limited mouse gesture compatability.
MyMobiler also allows IP connections, but they indicate this is slower.
I am now using MyMobiler with Win8 and a touchpad w/ multitouch, and the mouse gestures send very well.
For Windows V/7/8, you might need to run compatability mode on the Mymobiler.exe file. Navigate to the MyMobiler folder, which might be on your desktop. Drill down til you find the exe. Right Click and chose properties. Compatability. Run Compatability Mode for this file, and select XP.
More Notes:
These apps are slow, because USB is slow.
If you enable Fast USB on the phone, it will help speed up any Remote Display noticeably - however Fast USB is unstable, and doesnt work on some configurations. For me, it doesnt work on XP, but does on Win8 - though slightly unstable at times.
On the device: Start> Settings Icon>Connections icon >USB to PC icon. Tick box to enable.
Also, MyMobiler on Win8 will sometimes refuse to connect. Fully unload mymobiler, disconnect the phone, reconnect the phone and watch for activesync to confirm connection. Then reload mymobiler. Sometimes full system reboots are needed, but that's rare.
Windows Mobile Remote Controller app on CodeProject - as linked above, looks excellent. It's for Windows Mobile 7 and 8 - which is fantastic. He provides a rapi enabler to allow use with WinMo 6 / 6.5 devices, which also looks promising.
I've never used MyMobiler, so I can't help there, but how about other options?
Did you look at the Windows Mobile Remote Controller app on CodeProject?
I've had good luck in the past with SOTI's Pocket Controller. It once was free, or had a free version anyway. Not sure if they still do.
Windows CE came with a tool called CERDISP (short for CE Remote Display), which could be built with Platform Builder. I've seen it available as a binary download (like here, for example) on the web before, so no need to actually build it yourself.
I've used MyMobiler (remote.exe.50) on my Windows Mobile 6.5 handheld. It sounds like you got it running. Did you run the MyMobiler client on your Windows 7 box and connect to your handheld by IP address? (Right click on the icon in the Notification Area on Windows 7 and choose "Connect IP...".)
It defaults to the ActiveSync address (169.254.2.1?), so if you're not docked and running ActiveSync, it will fail to connect initially (but manually connecting should work). Misread -- you were able to run the client, but not the server.
You can also elect to run a VNC server on your handheld and use a regular VNC client to connect to it. I've built this one for Windows Mobile 2003 without much of a hitch on Visual Studio 2008. You might have similar luck with Windows Mobile 6.5.
EDIT: If you get the message that reads:
'%s' is not a valid Pocket PC application.
when running the MyMobiler client, then that means that your CPU type (or OS) is incompatible with the application -- so I don't think your PXA32X-P is to blame; especially since the MC3190 appears to be able to run Windows Mobile 6.5 (i.e. the CPU should be "fairly" modern, with support for armv4i). But since you haven't mentioned an error that looks like that, I'd suspect that your build of Windows CE 6.0 doesn't contain all the required dependencies.
The first thing I'd check is if all of the dependencies of MyMobiler are present in your build of Windows CE 6. Windows CE is highly customizable; as such, not all software components will be the same across different builds of Windows CE. MyMobiler is built targeting Windows Mobile, not Windows CE, so there's a good chance that your build of Windows CE on the MC3190 doesn't have what's required, while the video you linked does.
With regards to the ActiveSync Remote Display Power Toy, the message that you received sounds like the desktop application didn't know what version to deploy to your device.
Per readme.txt in the ActiveSync Remote Display package:
If you see error message "The OS or CPU of this device is unknown to
this application", it usually means the CPU type of the current
device, typically a Windows CE device, is not recognized by this tool.
The workaround is
1. Find the CPU type of the device (from the manual or the manufacturer).
2. Copy \Devices\wce400\\cerdisp2.exe to the \windows folder of the device.
3. Run "cerhost2.exe -m" on the desktop/laptop.
4. Run cerdisp2.exe on the device.
5. When the remote display is no longer needed, terminate cerdisp2.exe on the device.
You should be able to choose the armv4t version; if not, use the armv4 version.

Download internet browser for windows ce

I have a Motorola MC2180 device running CE6 and for some reason it did not come with Internet Explorer.
Where can I download a version of an internet browser that runs on CE. Please, if possible direct me to the download rather than just suggesting a browser that may work. I've been trying different browsers for a while, but none of them have a .cab file installer that I can run on CE.
Thank you.
You'll not find a download for IE because Windows CE is a modular OS. Simply providing the IE is not enough, as it requires a lot of other OS-level dependencies that may or may not be there. There's no way to provide a new coredll.dll that contains those required pieces in a download, it has to be built and fixed up for your target. IE also changes the license SKU from Core to Pro in 6.0, so it would be a licensing problem as well.
If you want IE, you'll have to ask Motorola for a new OS image that creates it. If you don't care exactly which browser you have, then follow #yms's advice and look at Opera Mobile, MiniMo, or one of the other browsers with CE support.
The MC2180 does not have IE, because comes with Windows CE CORE edition, this ed. does not contain IE, the MC2180 is an economic range solution. They are other solutions available according to your needs.

You could try with Opera Mobile. It may work on your flavor of Windows CE 6.0.
