IOS conversion from VxWorks 12.03

I have heard a rumor that you can not update to IOS from VxWorks 12.03. YOu have to go back down to 12.02 and then upgrade from there......Does this rumor have any merit?
Thanks

There is merit to the rumor. Cisco does not recommend performing an IOS conversion on a 12.03T VxWorks AP because of a problem with the flash overwrite. It's possible that the conversion may be successful, but there is a chance of it resulting in a non-recoverable situation.

  • Cisco AP350 Vxwork to IOS Conversion

    Hi,
    I'm trying to convert my cisco 350 from VxWorks to IOS. In the middle of uploading I received an error. Unable to detect source AP: Check: 1. Network connectivity, 2. User's Capability and 3. Whether SNMP is enabled in the source AP. However I'm unable to connect back to the AP using the browser interface. I also tried using the IPSU tool to get the IP address from the MAC address and that return a message "Device does not answer." Is there any other way to connect to the AP and reconfigure it? Any help is appreciated.
    Thanks,
    Mike

    Not sure what status screen you are referring to but if you follow the procedure below verbatim, you should be able to recover it.
    Recover from a Failure
    The menu that displays after the boot process is the VxWorks bootloader, which is functionally equivalent to ROM monitor (ROMmon) in Cisco IOS Software. Neither of the full operating systems is loaded or available, so neither of the full command sets is available.
    Note: If the VxWorks bootloader has been upgraded to Cisco IOS Software ROMmon but Flash memory has no operating system available, the unit displays the ap: prompt. In order to recover from this condition, refer to the Using the MODE button section in the Troubleshooting chapter of the Configuration Guide.
    Use these steps to restart the conversion process and get the unit back up:
    1.
    If there is an 802.11a radio module installed (AIR-RM20A), remove it during the rest of this procedure.
    2.
    Verify that the connection settings in the terminal application are 9600-8-None-1 and NO flow control (not hardware or software).
    3.
    Format the Flash memory for the unit to accept the VxWorks upgrade image:
    1.
    Press Ctrl-Z in order to bring up the hidden Format menu.
    2.
    Press exclamation point (!, Shift-1) in order to choose Format.
    3.
    Press 3 in order to choose Flash memory.
    Note: 3 is usually the choice for Flash memory. But you may have to enter a different number, which depends on your setup.
    4.
    Press Y (Shift-y) in order to confirm the decision to reformat the Flash memory.
    The reformat takes a few moments, after which the bootloader menu appears again.
    4.
    Transfer the upgrade image onto the AP.
    Complete these steps in order to start the transfer of the upgrade image:
    1.
    Press l (lowercase L) in order to put the AP into receive mode.
    The file transfer protocol appears, and characters scroll across the line as the unit waits for data to flow to it.
    2.
    In Microsoft Windows HyperTerminal, choose Transfer > Send.
    3.
    Choose an appropriate file transfer protocol.
    4.
    Browse to the location of the AP1200-Cisco-IOS-Upgrade-Image-v3.img file on the hard drive.
    5.
    Select the AP1200-Cisco-IOS-Upgrade-Image-v3.img file and click Send.
    When the file transfer is complete, the bootloader menu appears again. A file list also appears, which shows that the files that are compressed inside of the AP1200-Cisco-IOS-Upgrade-Image-v3.img file are now located in DRAM in the AP.
    5.
    Transfer the files to Flash with the copy process.
    Note: The files must be in Flash memory.
    Complete these steps:
    1.
    Press c in order to copy.
    2.
    Press 3 in order to choose the Flash memory as the destination.
    3.
    Choose the appropriate option for each of the files that are listed in DRAM.
    4.
    Repeat Steps 5a through 5c (the c ... 3 ... file option cycle) for each of the files that are in DRAM.
    Each time that you repeat the cycle, the bootloader menu and file list appear and show the progress of file copies from DRAM into Flash memory.
    6.
    Power cycle the AP.
    The upgrade proceeds as expected. During a successful upgrade, you see output that is similar to this:
    flashfs[0]: Checking block 25...bad block number (-1)
    flashfs[0]: erasing block 25...done.
    flashfs[0]: Checking block 26...bad block number (-1)
    flashfs[0]: erasing block 26...done.
    flashfs[0]: Checking block 27...bad block number (-1)
    flashfs[0]: erasing block 27...done.
    7.
    After the upgrade finishes successfully, reinstall the RM20A as needed.

  • IMessage - "new conversations from" ios 7   iMessage backups

    Hi, So I'm having two issues at the moment but I'll start with the "new conversations" issue. I just upgraded to the 5S and did a iTunes restore on the phone, restored using my backup and then activated iMessage which took a few hours before it actually happened. Any time I try and start a new conversation from my mobile (cell) number, iMessage automatically sends it as a standard SMS message (green) and not as a blue iMessage but when I start the conversation from an email address, iMessage works as normal but from "Messages" on my Macbook, I can send from my mobile number just fine so I'm not sure what's wrong.
    The second issue I'm having is that on my Mac, I have way more messages from one of my contacts, they go back quite a while but on my iphone they only go back as far as start of September. Any way how I can get iMessage on my Mac to force sync to my iphone and reload all my messages?
    Regards,
    Michael

  • Catalyst 6509 Conversion from CatOS to IOS.

    Hi,
    I am converting a Cat6509 Sup720 CatOS to IOS.The switch also has a FWSM configured. During converting CatOS to IOS will the FWSM configuration be erased or affected by any means ?
    Regards
    Kas

    there should be no affect or deletion/problems with the FWSM during your IOS conversion.
    haven't seen any issues in my LAB. the conversion process has a part where the CatOS commands/config are converted to the IOS commands/config required.
    you should make sure you backup the FWSM configuration and partitions before you begin.
    please see the following link for the CatOS to IOS conversion tasks for the sup720:

  • I am unable to add a call to make a conference during a conversation from my iphone 4s

    I am unable to add a second call to make a conference  during a conversation from my iphone 4s with ios 5.1.1. The option to add a call is not accessible (dim) on my phone whereas the same is accessible on my second phone. Both phones have the same carrier which allows conferencing.

    My apology for the typo.  The plus sign "+" was supposed to be in the quotes in the second sentence.

  • IPhone 6 plus- how to delete some of the texts feeds in a conversation from a sender without deleting all texts from sender?

    How can you delete some of the text messages  from a sender without deleting the entire conversation from that sender? After selecting the message or messages...the top left option is "delete all" and the top right says "cancel". I simply want to save some of the history of the texts and delete those that are no longer needed.

    Hey Mari7Can,
    Thanks for the follow up. Hmmm…the options should have shown at the bottom of the screen. Let’s try forcing the Messages application to close and restarting your phone:

  • Sync old iMessage conversations from iPhone to new iPad & Mac?

    I have had my iPhone for a couple years now, and have accumulated a fairly large amount of iMessage conversations from various people. A few days ago, I purchased my first iPad and also updated my Mac to Mountain Lion. By doing so, I now have access to iMessage on three devices in total, whereas before I only had one.
    I have managed to setup my devices so that all new iMessages I send and receive are being synced between them. However, is it possible to sync my old iMessage conversations from my iPhone back onto my iPad and Mac?
    I would like to do so in order to keep a full record of the past conversations I have had with my contacts.
    I have done a bit of research before posting, but the only related topics I found werehttps://discussions.apple.com/message/19095937 andhttps://discussions.apple.com/message/17818920. The former was left unresolved, whereas the latter describes a solution which I am unable to reproduce.
    Could anyone shed some light on this for me?

    Hi,
    For me this was very early on in my Mountain Lion days.
    I would now say that you cannot sync iMessages from an iOS device that were sent before your linked any Apple ID with the iPhone Number or added the Mac to the use of the Apple ID.
    At the point at which and Apple ID is used on both an iPad and the Mac version of Messages becomes it's "Start date"
    The same can be said for adding an Apple ID to an iPhone and the Mac.
    On the Mac all messages can be saved if you wish.
    This are in the .ichat format which you can send to Mac  Buddies and then can open them and read them as if they were the chat (i.e they display as "chats').
    There appears to be no way in iTunes to access the iMessages (or SMS ones) on the iPhone.
    Someone who knows more about the iOS may be able to tell you if they are accessible another way.

  • Imessage sends messages from email despite selecting phone number for "start new conversations from"

    On both my phone and my computer I have selected to start new conversations from my phone number, but just now I continued a conversation from my macbook and it sent it from my email address instead of my phone number! All the other answers I found for this question were outdated, I couldn't find "Caller ID" in settings for iOS 8 or Yosemite.

    If this is a continuing conversation, I don't believe the device looks at it as a new conversation, which is what that setting is for, from what I understand. If there is a checkmark by the phone number on all devices, then it should start there, but if the conversation was originally started from the email, I believe it will continue until you start a new conversation.

  • Restore an iMessage conversation from Mac to iPhone

    Hi,
    A couple of months ago, I deleted a contact from my address book, along with the corresponding iMessage conversation from this contact.  Both the contact and the conversation were manually deleted from my Mac and my iPhone (I think, although maybe I just deleted it from my iPhone?).  Both devices are using the same AppleID/iCloud account.
    About a month ago, I added the contact back in (I can't recall if I added the contact back on my Mac first or my iPhone first) and the entire iMessage conversation had been restored on my Mac (I was actually quite amazed that the entire conversation was restored on the Mac.  I didn't really know that all that is stored in lCloud).  On my iPhone, however, only the iMessage conversation messages that were exchanged since the contact was added back in are present on the iPhone.
    Is there a way to force the iPhone to refresh the entire conversation from this particular contact from iCloud, or from my Mac?
    I use iCloud backup to back up my phone, not my Mac.
    Thanks!

    Not that I know of. You would have to restore a back-up of the iPhone before the message was deleted. You can also take screen shots on the Mac of the conversation. That would save the conversation in your photos, and you can sync those. Maybe someone else can chime in if I'm missing something.

  • Getting ÿþ as saved conversations from Lync in Outlook in Office 2013

    Hi,
    I've been trying to get to the bottom of this and have found similar posts, but no one seems to have an answer.
    When I IM someone using Lync 2013, they get a pop up notification but instead of the message they see ÿþ<.  Once they open the chat window, they can see my typed text.  Occasionally, certain people can't see the first line of my chat, but as
    long as they keep the chat window open, they can see everything new I type.
    All my conversations that are saved in outlook show ÿþ< for the text and are unreadable.  I've disabled the saving of conversations because they have become worthless.
    I believe it has to do with BOM but have not been able to find a way to fix this.
    If I copy a conversation from the chat window and paste it into Microsoft Word it shows ÿþ<, but if I paste it into notepad the conversation appears.
    (I had inserted a screenshot here, but am unable to because I am unable to figure out how to get my account "verified")
    I've tried changing the preferred encoding for outgoing messages: to Unicode (UTF-8) in Outlook, but this had no effect and I can't find a similar option in Lync 2013.
    (I had inserted a screenshot here, but am unable to because I am unable to figure out how to get my account "verified")
    I enabled logging for Lync and the event IDs that come up are 1, 11 and 12, to which I cannot find any information for at the moment.
    Any help and or suggestions would be appreciated.

    Hi,
    Did the issue happen only for you or for multiple users?
    Please try to delete Lync User Profile and information on Registry, then repair Office 2013.
    The path of Lync User Profile: %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
    The path for information on Registry: HKCU\Software\Microsoft\Office\15.0\Lync\[email protected]
    Then test the issue again.

  • How can I prevent the Videos in iOS 8 from automatically playing the next episode of a TV Show?

    I noticed that, after updating my iOS device from iOS 7 to 8, that when it's finished playing a TV Show episode in the Videos app, it begins playing the next one. I like to fall asleep, listening to a single episode knowing that it'll stop and eventually let my iPad fall asleep, but with this change in iOS 8, it will play through the rest of season before doing so.

    Thanks.
    I noticed you bolded "Apple-branded apps" from the first sentence of section 2 (c).
    What is the definition of "Apple-branded" in this context?
    For example, "Apple Watch" is now a preinstalled app, and would seem to fit the definition of "Apple-branded", but I can't uninstall it.

    Thank you,

    So what happened to the phone during the process?  It should have gone black and restarted a couple of times and there would have been a white progress bar as the update installed.  Sounds to me like you've downloaded the update file but not actually installed it.  The quickest way to see version of the software is installed is to go to Settings-General-About and check Version.
