My iP 4S auto goes on DFU mode (I think so) ?

Hi all,
My 4S (brand new) do not "wake up" when I press Sleep/Home button twice a day. So I must press and hold Sleep and Home about 10s then release Sleep button to restart. I restored to the lastest iOS (5.1.1) but this happens again.
Can anyone help me to fix this?
Thx!

This program got me out from the loop. I dont know sharing it here is legal or not. But it is the solution for this problem. However I'm still wondering why I faced a problem like that. Is an update is that hard?

If it's an original iPhone, you may as well dispose of it responsibly and buy a new phone. Apple stopped servicing them a while ago.

Apple will exchange your iPod for a refurbished one for $99 for 16 GB 5G and $149 for the other 5Gs. They do not fix yours.

Fix it yourself if you are up to it. However, that is very hard when yo do not know the cause.

Everytime I try to restore a backup on my iPhone 5 from iTunes the phone goes in DFU mode and stay stuck

i backed my phone up on itunes and then I changed the battery on my own. the problem is that I can set the phone as a new one but when I try to restore a backup it goes on DFU mode and stay stuck. What can I do?

Once you opened the device you voided any post-warranty support from Apple or the forum. You are on your own. You can try a 3rd party repair facility, but you cannot get any help here or from Apple.

Iphone 3g goes into DFU mode by it's self

hi guys
my iphone 3g goes into DFU mode by it's self is there someone who knows what should i do for it?
by the way i made a restore and updates and everything possible i thought maybe there was an application pushing it to go in dfu mode so i left only the necessary apps but still the same it goes off when someone calls me they hear the ringing like if it's on i connect it to the pc and it's detected as dfu mode!!

from a back up of course otherwise i'll loose all my informations as contacts, mails,...etc
to be more clear last thing i did is:
it was running on os 4.0 so i did update it to 4.2 then restored it from the back up

HT201263 My ipad will not show the recovery mode, it goes into DFU mode just fine, but whenever I put it in recovery mode I get nothing but a blank white screen. After doing a restore or update itunes gives me error 37. This all happened due to a failed u

I updated from ios 5.0.1 to 5.1. Midway through the update itunes crashed. I got it all working again and ever since I have been stuck in a recovery loop. DFU mode works fine, but when I go into recovery mode (yes I am doing it right, yes I have tried pwning, tinyumbrella, etc.) it still just gives me a white screen (I am not getting the plug arrow and itunes icon screen that shows up when you are in recovery mode). I am a huge fan of hacking, mods, and jbs, BUT have never done any on the iPad, (found it pointless).. nevertheless, I am stuck thanks to apple in a white screen and a nonworking iPad. If anyone has any ideas that does not include jbs, updating, restoring, restoring with internet off, restoring in DFU, I would gladly appreciate it. I would take it to the apple store but it was a friends and I didn't purchase it. My friend had the issue formerly and they had no idea what to do at apple (they usually try DFU, restore, and then have nothing else to tell you.

There's a whole lot to read in your post, and frankly I have not read it all.

I put my iPad into DFU mode without thinking much about it. I didn't realize I would lose everything. Is there a way to get everything back the way I used to have it before I tried recovering my iPad?

A couple of days ago my iPad died, so I plugged it in to charge. It went into a rebooting loop, and when I looked up how to fix this, I saw that I can put my iPad into DFU mode to fix certain things like this. I did, not thinking much about it because l had seen both of my parents get new phones and everything was slowly but surely on their phone the way it was on their old phones.
I thought that even though I agreed to the iPad being put back into factory settings, I thought I would be able to get everything back the way it used to be just by logging into iCloud when setting it up. I was wrong. This is a school iPad, so all of my notes are gone. The only things that were backed up were my photos. All the games, social media, etc. that I had downloaded prior were gone. Even my notes.
Is there a way I can get everything back to the way it used to be, or was agreeing to put the iPad back into factory settings the wrong thing to do? Was it a mistake to take it upon myself to fix my iPad in this restarting loop? I would really like to get everything back, especially my school notes.

The only way to get everything back is by restoring a backup. If you didn't have a backup, there is nothing that you can do to recover your lost documents and your notes. If you have a backup restore the backup in order to recover your data. Purchased apps can always be downloaded again as long as you use the same Apple ID that you bought them with, but data can only be recovered from a backup or if you have copies of the documents and notes on a computer.

IPhone 4 keeps going out of DFU mode when trying to reset

So I was helping my dad with his iPhone 4. It just stopped working from time to time.
When I tried turning it back on at those times, it just stops at the recovery mode screen. I then tried having it plugged in while I had iTunes up, but that didn't help. Error 21, iTunes said.
So I tried putting the phone in DFU mode and then resetting it to factory settings. But during the reset - when it tried to contact the Apple servers - the phone went straight from DFU mode to Recovery mode which gave me the error 21 again.
I've tried all of the tips in the help section (making sure that the computer was up-to-date, I made sure the security program was turned off etc, I deleted the ipw and had iTunes download it for me again), but that didn't help either. I even tried to start iTunes as an administrator, but that didn't help either. The account on the computer is also an administrator.
So what should I do now?

http://support.apple.com/kb/TS3694#error21
Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.

How to prevent auto reboot, springboard crash & going to safe mode?

iPhone 3GS used on 3.1.2 and now upgraded to 4.0.1
Problems:
* It crashes automatically & reboots
* When left idle screen goes blank, no response, caller hear the bell ringing but phone indicates nothing. Finally requires a force reboot. I don't see any missed calls too (only with 4.0.1 and did not observe with 3.1.2)
* Start any application and app crashes, sometime springboard crashes and goes to safe mode, even just sliding for unlock causes the crash
* I observe this problem even immediately after restore, nothing additional installed

Is this looking like to be a hardware problem?
Can I take it to any apple store & get fixed?

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

IPad No Display - Goes to DFU if left ON - iTunes detects in Recovery

Hello World,
I have an iPad2 WiFi 16GB that has gone dead. I was perfectly working a few weeks back but now it’s almost dead.
The problem was first observed on a morning when I tried to press the home button and the screen wouldn’t come on. I thought the battery was down and tried to charge it. Having connected it to a charger, there were no charge indications displayed on its LCD. Usually I see the red battery charge icon when connected to a power source. In the evening when I came back from office, it was still stuck on the blank screen with zero display no backlight either. I swapped with another charger but still the same story. Then I tried to hard reset it, and viola, the screen powered up and booted back again. No issues for 2 days. Then the same problem on 3rd day and so I hard reset it again and when it booted back I noticed that the charge was about 70%. So I knew the problem was not due to low charge. This started going on for a month. As time passed I couldn’t hard reset it straight away and it was getting tougher to get the iPad working. I would have to keep pressing the home button and power button for more than 20 seconds for the screen to come back up. My chances of waking the iPad was better if I connected it to a charger and if the battery was charged above 90%. It became harder and harder to get the iPad working. I observed that if the iPad is always connected to the charger this problem never happens. You can leave it for a week and no issues at all. It is when there is no charger connected to it and if the iPad blanks the screen due to inactivity and within 10 minutes of standby the problem starts to appear.
Since this was happening quite often I thought it could be a problem with the recently updated 7.0.4. So I thought I would upgrade it to 7.0.6 and see how it goes. With the blank screen iPad I connected to its USB cable and to my surprise iTunes detects it in DFU mode. This is the DFU with blank screen not the recovery screen that shows up with "Connect to iTunes picture" on the screen. But, if I try to update the iOS it would get stuck at the progress bar forever. No activity is observed at this point. The only way to reinstall the OS is try to hard reset the iPad by pressing the home + power buttons for more than 20 (if you are lucky) seconds and see if it comes out from DFU with a boot logo of Apple. During power up keep pressing the home button so that it enters into the recovery mode ("Connect to iTunes picture"). Then iTunes can reinstall it. But when it reboots same problem. So I know it’s not the iOS issue. Something else would have gone wrong. As time passed by the iPad wouldn’t wake up at all. It wants to be in DFU all the time. The 20 second hard reset work around too failed and it was impossible to get the iPad working. I thought it could be the battery playing up. So I purchased the iPad2 battery off ebay for $13 and replaced it. The multi-meter showed it had about 3.4v before replacing (the one in it showed about 2.8v). But, still the same issue. There is no way the iPad displays anything except if I connect to iTunes and try to reinstall the iOS. In that case it would get stuck in the progress bar at 0% with the Apple logo on top.
I need some expert opinion here. Taking it to apple for repair is not an option and the iPad is out of warranty. I would like to repair this myself and would like to know the cause of such an issue. I am an advanced user so any wise observation, expert opinions are welcome. Appreciate your time in advance.
Thanks
Sinu Chacko

I also have had this problem, although it's not application specific. It can happen when I'm in any application including Safari, Photoshop, MS Office, Dreamweaver. (I don't have any video games installed). Would love to know if anyone has any answers out there!

HP PHOTOSMART ALL-IN-ONE 5510 WONT PRINT AFTER GOING TO SLEEP MODE

My printer model:
HP PHOTOSMART ALL-IN-ONE 5510 B111A
Problem:
Printer goes to sleep mode. After 25-30 minutes the wireless connection between the PC and the printer breaks. Blue Wireless light is on even at the sleep mode and I can see that the printer is connected to my router and there is internet connection. HP Print and Scan Doctor sees the printer but I cannot awake the printer unless I restart it.
What I have tried so far:
I have tried all the solutions hp.com offered including; reinstalling driver, updating printer software, setting static IP to printer, setting static DNS servers, using HP Print and Scan Doctor.
I have seen people asked about this question before and there was no solution. I really need HP help!
This question was solved.
View Solution.

Let’s try this. Verify in the printer that 'Auto Off' is disabled. Set a static IP in the printer outside the DHCP range of the router. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest. Set router to 20Mhz only, or 145Mbps depending on router. Always use WPA2-AES encryption. Power off both. Power on router wait 3 mins. Power on printer and verify it reconnects to router. Now try.

IPod Touch 3G in DFU Mode and won't come out

Hello,
My daughter's iPod Touch 3G appears to be in DFU mode, but won't come out. The screen is completely black, and when I attach it to the computer, it comes up with the message "iTunes had detected as an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes." When I hit the restore button, I receive the error message "software for this iPhone is not currently available. Make sure you have the latest version of iTunes and try again."
I've seen this message posted several times in the forum, and I have tried all the troubleshooting tips offered by Apple Support and in the answers to some of the questions. I am a Systems Engineer, so I consider myself pretty technically savvy. These are the steps I have followed so far:
1) Completey removed and reinstalled iTunes according to the instructions provided by Apple.
2) Downloaded the firmware for both the 3G and IOS4 from http://www.felixbruns.de/iPod/firmware/ and attempted a manual install - when I do this, I receive the error message, "the iPhone "iPhone" could not be restored because the firmware is incompatible"
3) Downloaded RecBoot to attempt to exit recovery mode, but it does not appear to be detecting the iPod.
4) Attempted to exit and re-enter DFU mode several times to no avail.
5) Called Apple Express Lane and was willing to pay the 1 time phone support charge, however the agent told me that he could not help me, and that I needed to take the iPod into an Apple store (the iPod is 190 days out of warranty).
My last effort is to try the install from another PC. So, prior to taking the iPod into the store, I was wondering if anyone has had any success other than the steps I have tried above. I'm appreciative for any assistance anyone is able to provide.

Check the model number on the back, "A1318" = 3G, "A1288" = 2G. If it truly is a 32GB 3G Touch, then you're going to have a rough time going back to an iOS version earlier than the current release (4.3.1, available from iTunes). The iOS packs you get from the site you mention are not "signed" and you probably won't be able to install them ... I think 2G owners have better luck with those "unofficial" versions.
So, if you have a 3G, your best bet is to erase (or move) all earlier iOS versions and let iTunes download a fresh copy of 4.3.1 for the iPod -- no need to go to a 3rd party site. If you have a 2G, then the latest version you can install is 4.2.1, which is also available from iTunes. To increase your odds of this working out, you might temporarily disable any AV software and firewall(s).

Error Code 21, iphone 4S stuck in DFU mode and will not restore!

Hi All,
My brand new Iphone 4S will not switch on unless it is connected to the charger/usb connection to the laptop, before we go any further the battery is fully charged. When you connect the phone to the charger plug you can go through the set up routine until a point is reached when it displays "conect to itunes" however, as soon as you disconect the usb cable from the charger plug to conect it to the laptop it appears to just switch off and then display the apple logo, the screen then goes blank and then the logo again, it carries on doing this indefinately.
I can get the phone into DFU mode and itunes will recognise it, IOS 5.0.1 downloads and it attempts to restore the phone but I then get an "unknown error message (21)" I just cant get past this point, I have also tried the restore procedure on a friends Windows laptop and a MacBook Pro but still no joy.
I have booked an appointment at my nearest Genius Bar (which is miles away) on Thursday but I could well do without having to make this trip, can anyone please advise me if there is something else to try?
Thanks in advance.

Thanks for the reply, yes I did disable my firewall and antivirus software staight after my first failed restore attempt but it made no difference, like you I also checked out the error code explination.
What I cant understand is why dosent this phone does not work straight out of the box?...its brand new, I have not tried to jailbreak it, (I have recently seen this as a possible cause in another post) I just want the bloody thing to work!
I also forgot to mention in my post that the phone will not respond to any key presses or show any signs of life unless it is conected to a power source and beleive me it has spent most of the last 2 days conected to one due to this, the battery indicator shows it is fully charged.
Any more help is very much appreciated.
