Switch Upgraded to 15.2-1.E1 From 12.2-55 and switch is not operable
Hi
I need help if somebody has a solution for this problem
I have a batch of new Cisco 3750X. Open box, it load without problem, it coming with IOS 3750-eUniversal 12.2-55. I have an USB with the new code c3750e-universalk9-mz.152-1.E1.bin , copy code from USBFlash0: to flash. Them change the boot system to the new IOS, check the registry everything is ok.
Save memory, and reload the switch..
Now switch never comes up, it is on, there is noise, the led in SYS in on.
But nothing coming in the console.
If IOS is corrupted it will coming back on boot> prompt
Nothing waiting for long, long time and nothing. Turned of tunr back on and nothing
Somebody had the same issue?

I've got good news and some bad news for you ...
Good News: When you upgraded the switch from 12.2(55)SE to 15.2(1)SE1 the new IOS will upgrade the Bootstrap. Guess how long this'll take? Approximately 35 to 45 minutes. And your switch will sound like a Hoover vacuum cleaner or a Boeing 737 spooling up for take-off. It's loud.
My recommendation is to turn on the appliance and go have an early lunch. By the time it comes back, it should be ready for you.
Bad News: After the upgrade, I strongly recommend you DOWNGRADE your IOS (another bootstrap upgrade). Use 12.2(55)SE8. Avoid using 15.2(1)SE1 because the entire train is very buggy.
Hope this helps your issue.

Help! I recently upgraded to OS 10.9.4 from 10.6.8, and now when I want to send an email to a group in my contacts I am no longer able to select the group as a whole. I have to select each address individually. This can't be right. With 10.6.8 I used to be able to double click on the name of the group and they would all be selected. I've also noticed that my address book is now called "contacts." Thanks in advance for your help.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
computer and after the chime press and hold down the OPTION key until the boot manager
screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall the 10.9.4 update: OS X Mavericks 10.9.4 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.4 update: OS X Mavericks 10.9.4 Update (Combo). -
I need to upgrade to mac os snow leopard from 10.5.8, and have the lion OS usb. I can't upgrade to snow leopard as my father doesn't remember the admin password. If anyone can help it would be appreciated
Restart with the Mac OS X 10.6 DVD in the drive or with the Lion USB drive connected, hold down the Option key just after the restart, tab to the installation disk, and press Enter. If the computer has a firmware password set, it needs to be provided for this to work.

I have an iPhone 4s, but wifi the option is greyed out. The wifi stopped working on it months ago. Now I wanted to erase all content and setting from my old 4s and it will not connect to the internet, because the cellular data is no longer connected, since I bought a new iPhone 5c. I can't erase my phone by pluggin it into my Macbook Pro, since I can't disable the "Find my iPhone" App without internet. How do I erase all the data and setting on my 4s without connecting to the internet? It is running ios 7
See this https://answers.yahoo.com/question/index?qid=20131119125513AAtRloc
I just did it. To enter DFU mode, I had to use "method 3" on this post
http://thebigboss.org/guides-iphone-ipod-ipad/dfu-mode
Too bad my 4S is 2 years old. Wifi is dead. I had to upgrade to 5S, but 5S is soooooo much faster than 4S so it's kind of good outcome. Without the 4S breaking down, a stingy person like me would have never upgraded the phone. -
You have taken 1.58 from my debit card and i do not know what for. There is no history for it. Please tell me what it is for. Thank you
We are fellow users here on these forums, you're not talking to iTunes Support nor Apple, we won't know.
Have you added or changed your credit card details on your iTunes account ? If you have then each time that you do so a small temporary store holding charge may be applied to check that the card details are correct and valid and that it's registered to exactly the same name and address as on your iTunes account - it should disappear off your account within a few days or so.
Store holding charge : http://support.apple.com/kb/HT3702
If not then you can contact iTunes Support via this page and see if they can help : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption -
I just purchased Final Cut Pro from the App Store and it will not download to my computer. I try and install it from my purchases file but nothing happens. Any suggestions?
If it's in the purchased page and doesn't download, you should contact Apple.

If you mean the DL appears to be stalled give it about half an hour, if there's no movement restart and the DL should pick up from where it left off.

I've accidentally deleted purchases from appearing in iCloud, and iTunes will not even let me re-purchase them, let alone make them appear in "previous purchases" to download.
Are the items still available in the store, and if so have you hidden them (hiding and unhiding) ? Not all content types are available for re-downloading in all countries, and if the content provider has removed an item from the store then it also won't appear for re-downloading.

We got a iPad from a late relative and we do not know the Apple ID and the password so we can't get into the ipad
I have heard that in the case of a death, if you can prove that the original owner is deceased and that you are a legitimate heir, Apple may be able to help you. We, here, can do nothing for you. Contact Apple--you will find contact infromation at bottom right of this page.
