Error entering DFU mode ( apple tv 2 )

i have apple tv 2
but i cannot set DFU
i got message : error entering DFU mode
the remot color is silver

Fixed it.
I got tired of dealing with it, so I unplugged the power and left the USB cable plugged in (purely being lazy). After a day or so and several reboots I decided to try the restore one more time. Surprisingly, iTunes still recognized the ATV was plugged in even though it didn't have power. So I let it download and update the device. Somehow it worked with no power plugged in, but I am now enjoying my ATV again. Good luck to everyone else!

I sleep my iPhone 4 and then it enters DFU Mode?

So basically, I downgraded iOS 7.0.6 (because it looks horrible and it's laggy) to iOS 6.1.3 on my iPhone 4 using a custom firmware I created with my SHSH Blobs for iOS 6.1.3. During the restore, I get error 37 and have to boot it tethered with a recovery fix in RedSn0w so that it will boot. So I syncronized my iPhone with iTunes so all my movies and music were stored on the phone. However, I press the sleep button and then after about a minute, it just shuts down, enters DFU Mode and then won't boot up again. Any suggestions on how this can be fixed?

Congratulations. You've rendered your phone unsupportable. Downgrading is not supported at all.
If it won't restore in DFU mode, you've permanently bricked it.
Buy a new phone.

My iPod Touch in need to enter DFU mode

My iPod Touch got stuck on the apple logo, and there is no way to get out of that instead of entering DFU mode and restoring my iPod Touch, but my iPod Touch 4th Generation (sleep/wake/power) button is broken and can't enter DFU mode without press that button and the home button, any programs or any pther things that can help me get into DFU mode while I'm stuck on the apple logo and without using the buttons?

All Apple wants is the iPod itself, if that's all you're having problems with. They will not need the packaging, nor any of the accessories unless you're having problems with any of them. As to "what you say", you'll tell them what the problem is.
Regards.

Why are you entering DFU mode? DFU mode is not supported by Apple.

My iPod Touch Won't Turn On, Charge or Enter DFU mode

Hey, one day my iPod just wouldn't charge anymore,I though my charger was the problem so I bought a new one, and it still didin't work so I tried another one and still nothing. When my iPod turned off because of low battery it would not turn on again. Then I thought my battery was the problem so I had it changed at the store and it still didn't work. I tried to enter DFU mode and recover, but it just won't enter DFU mode (and no, I'm sure I'm not doing it wrong, I did it before). I hope this is somehow fixable because people at the store didn't know how to fix it and I don't really have to funds to buy a new one. And also, store I was talking about isn't apple store because we don't have them here in Croatia, so I can't really get a new one for free...

Well... since I have been with it in all services in my area and none of them know how to fix it, I guess I'll just have to buy a new one eventually... thanks anyways for replying...

My iphone 5 is frozen on the screen that shows a cable and itunes symbol. I can not get the phone to enter DFU mode and itunes does not recognize the phone when plugged in to itunes. The phone was mid update when it was disrupted....

I plugged my iphone in to do an update and it was mid way through the update when the phone was accidentally disconnected. Now the phone is stuck on the screen that shows a cable and the iTunes image suggesting the phone needs to be plugged in to iTunes. I have plugged it in, powered on and off, attempted to enter DFU mode numerous times all with no success. ITunes does not recognize the phone and I continue to only receive the screen saying I need to plug in to iTunes.. Please help!

Hold Sleep Button with Home Button toghether until it restarts Always it takes 8 to 15 seconds, after it restarts leave the sleep button and remember do not leave the home button it automaticlly switches to DFU mode.

HELP!!! Blank iphone screen with an apple logo that keeps flashing. Cant restart phone or enter DFU mode because power button is broke. HELP PLEASE

Woke up this morning and phone was working fine up untill I went to switch apps. It then froze up on me and the screen turned black. Its fully charged and I thought that it mightve just turned itself off so I held on the home button and lo and behold the apple logo came up! I thought my problems were fixed but after about 10 seconds of the logo being up the black screen of doom came back. The apple logo comes back about every 80 seconds. Now it is just a black screen and completely unresponisive to everything Ive tried. Ive called the phone and it rings completely through as if the phone is on but the phone itself does nothing. I would try resetting it or putting it into DFU mode but the power button is broke. I cant figure this out. PLEASE HELP!!!

you're boign to have to get it fixed. There's no way out of this without the ability to force it into Recovery or DFU mode.

Ipod not charging and it doesn't enter DFU mode as it is in a recovery mode loop. Can you please advice what i could do to solve this problem. Thank you :D

I have being using ios 5 beta 3 for a few days. It didn't charge my iPod so i thought of downgrading back to ios 4.3.3 but it didn't work so i put my iPod into Pwned DFU mode. When I tried downgrading it didn't let me. i restored back to iOS 5 beta 3 but then DFU mode didn't work so i tried another Restore and unfortuntely the battery went and i can can't charge it. It shows a black screen with a battery and telling me to charge the iPod.

Since your iPad is so new I would suggest-
If you bought it at an Apple Store, there is a 14 day return policy. Take the receipt, iPad, the box and what came in the box to the store and ask to speak with a manager and show him/her the problem and nicely ask to return the unit and purchase a new one.
Before going to the store make a Genius Bar appointment (http://www.apple.com/retail/geniusbar) and arrive at the store early and proceed with the first step I explained. The reason I suggest making an appointment is because the store may not have the 64GB 3G in stock to sell/exchange. But the Genius Bar may have it in stock to replace under warranty. So, if the manager explains that there are none in stock, then explain you have a Genius Bar appointment any way. If the manager says they do have them in stock to sell then explain you need to cancel your reservation.
If you can't or don't want to visit an Apple Store. Then call 1-800-MY-APPLE and speak with the customer service department.
Hope this helps.

Iphone 4 error 21, DFU mode doesnt work, hosts file is fine,

have the iphone 4 and I haven't used it since February 7th and its April 14th now and its stuck in recovery mode. I put it into DFU mode and it still doesn't work, everything is fine and I still can not find a solution, please help.

"Error 20, 21, 34, 37: These errors typically occur when security software interferes with the restore and update process. If you are using a PC, follow this article to resolve this issue."

My iPhone keeps entering DFU mode on its own, what to do?

Every time it does that i have to reset it. What should i do?

Try the standard fixes:
- Reset. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod

My Tethered iPhone wont enter DFU Mode?

Hi, my iPhone 4 is tethered by jailbreaking. And it shut down on me, it had over 50% battery power. And I am trying to boot it back up by using redsn0w. I held the power button for 3 seconds. Then held the home button and then released the power button. It said that it couldn't be identified. I went on iTunes because I switched my mind and just decide to have a non-jailbroken phone. But when it was plugged in, it was not identified. I looked and the computer also can't identify it also. I can't take it to a store because it's jailbroken so stores can't help. And I cannot erase it and get my items from cloud again. I am so stressed out. And I think its not possible to fix this. It can turn on, but can only go up to the apple logo menu. I looked all over the Internet but found nothing. I did everything I can. And I need help. With any answers, I will read them asap. Thanks!

IPhone 3GS won't restore (error 1600 or "not eligible for this build") no apple logo, recognised in DFU mode.

My iPhone 3GS decided to turn itself off (on 30% battery) yesterday and hasn't turned on since. After some testing (hard resets, DFU mode), tiny umbrella recognises it in DFU mode, as does Redsn0w. neither devices can successfully kick the phone out of the restore loop.
The screen stays blank throughout, no apple logo, connect to itunes logo etc. however every now and then the charging sign will appear (empty battery with a little bit filled (red)). even if i unplug it from my iMac the charging symbol stays there.
once I get the phone in DFU mode iTunes recognises that there is a phone connected that needs to be restored, it doesn't matter if I click restore or option + restore the process will fail on Error 1600 or "this device is not eligible for this build".
My iPhone is not unlocked or jailbroken. Before the incident with the coffee I managed to synchronize and update its firmware as indicated by iTunes. The latest update for my iPhone was iOS 5 firmware. My intent is not to unlock or jailbrake the device, just to make it work again.
Here are some things I've tried since:
1. Exiting recovery mode via Tinyumbrella
2. Entering DFU mode via Redsn0w
3. Shift + Restore and using firmwares from 5.0 to 5.0.1 to upgrade my iPhone.
4. Remove hosts to my Host file (in relation to the "device not eligible for this build" issue)
5. Try redsn0w and use IPSW to see if it is recognized by iTunes (iTunes recognizes the iPhone but then at the very last minute shows error 1600.
6. Save SHSH files and use Tinyumbrella to uploaded them to my iPhone.
I would really appreciate if someone can help me on this. I might be doing something wrong or maybe not even considering the right steps to solve this issue. I don't know if there are missing drivers that are preventing the device from communicating with iTunes properly. Of some tool that can be used to correct this problem. It may or may not be fixable but I think it is worth the try.
Thanks very much.

please ignore the comment about coffee. Someone posted a very similar question apart from he spilt coffee on his phone, I didn't.

DFU Mode. Is it possible in anyway to enter this mode without a computer?

Hello.
Me and my friend have a big argument about DFU mode.
* He calims that it is possible to enter DFU mode without a computer at all.
* I claim that entering DFU mode without a computer or any other external hardware is impossible at all.
* I also claim that it is possible with a software only, without phisicaly touching the iDevice using iTunes or any other software.
I also explained him that DFU is "Device Firmware Upgrade" and it must get connected with a PC or MAC to get into this mode.
Can someone professionaly explain us the correct answer so that we can finaly solve this issue?
Thanks in advance,
Asaf Moraz.

Exactly! while i connect it to the computer it just power on the device.
When i press the power again without forcing it through hard reset and without connecting it to the computer it just power up.
That's why i am allmost sure there is no way to enter this mode (DFU) without beeing connected to the computer and tha's what i tried to prove.
Thanks a lot for your time by the way...

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).
