如何重置iPhone限制密码

Alexandra Malureanu

由 Alexandra Malureanu

只需点击2次,即可从iPhone或iPad上删除家长控制

无法记住您安装的某些应用的限制密码?想要访问App Store并忘记您的限制PIN码?您想避免重置iPhone或iPad吗?

我们找到了一种重置忘记限制密码的方法,该密码可以很好地用于iTunes备份。使用iPhone备份提取器,您还可以从旧版iTunes或iCloud备份中恢复限制密码。如果您丢失或忘记了iPhone或iPad的限制密码,则可以轻松重置。

Forgot your restrictions passcode?
忘了你的限制密码?

如果启用了家长控制,则可以在任何加密或未加密的iTunes或iPhone或iPad的iCloud备份中使用iPhone备份提取程序找到限制PIN。通过在我们的应用程序中单击并恢复,可以将限制密码重置为1234

重置任何Apple设备的忘记限制密码

直到最近,有必要手动提取和编辑com.apple.springboard.plist文件以重置限制密码。我们使这个过程变得更加容易:iPhone备份提取器为您完全自动化了该过程 。你所需要做的就是:

  • 制作iPhone,iPad或iPod Touch的iTunes或iCloud备份

  • 下载并运行iPhone备份提取器 (适用于Windows和Mac)

  • 使用iPhone Backup Extractor打开备份

  • 单击“实用程序”菜单,然后选择“重置限制PIN”。备份中的限制密码将更改为1234

    Reset the restrictions passcode with a single click!
    只需单击即可重置限制密码!

  • 弹出窗口会询问您是否要继续此过程。单击“是”并等待几秒钟。您的新密码为1234

    Reset passcode popup
    重置密码弹出窗口

  • 现在,您必须在iPhone上恢复已修改的iTunes备份。只需将其连接到您的计算机,然后使用这些说明通过iTunes将其恢复。重新启动后,iPhone的家长控制密码将变为1234 ,您将能够解锁它。

    Succesfully reset restrictions passcode
    成功重置限制密码

看看我们的视频教程:

如何手动重置iTunes备份中的限制PIN - 免费

使用以下说明将限制PIN重置为iPad或iPhone上的1234 。如果您决定使用此方法重置密码,则需要遵循以下步骤:

  1. 在启用限制密码的同时在iTunes中创建备份。因为我们手动执行此操作,所以如果备份未加密则更容易。 (最好将备份加密并使用本指南前面的自动方法。)

  2. 浏览到默认备份文件夹 (通常是Windows上的C:\Users\[username]\AppData\Roaming\Apple Computer\MobileSync\Backup\或macOS上的~/Library/Application Support/MobileSync )。您还可以运行iPhone备份提取器并右键单击备份,然后选择“在Finder中显示”或“在资源管理器中打开”以打开备份的文件夹。

  3. 获取文件662bc19b13aecef58a7e855d0316e4cf61e2642b的备份副本,因为这是我们正在编辑的文件 - 如果出现任何问题,您需要备份副本...

  4. 使用在线SHA-1哈希生成器获取文件的哈希值662bc19b13aecef58a7e855d0316e4cf61e2642b - 记下这个哈希值(它将类似于a6533d4dc9ac9f8af7ba65cb955187f025cfde8b ,尽管每个备份会有所不同)。

    Hashing the restrictions passcode file -- spooky!
    哈希限制密码文件 - 怪异!

  5. 使用iPhone Backup Extractor的Plist编辑器打开662bc19b13aecef58a7e855d0316e4cf61e2642b文件。单击“ File菜单中的“ View / Edit Plist ,然后浏览.plist文件。

  6. 在文件中搜索以确保没有包含文本<key>SBParentalControlsPIN</key> 。如果有,那么它下面的行(它将读取类似<string>1234</string> )包含PIN。

  7. 如果该行不存在(它不应该在iOS5或6个备份上),则搜索<key>SBParentalControlsEnabled</key> 。下面将是一行<true/> ,表示家长控制已打开。如果该行丢失或者说<false/> ,则不启用家长控制 - 并且更改PI​​N将无济于事。

    Editing the restrictions PIN plist
    编辑限制PIN plist

  8. 假设SBParentalControlsEnabled键为<true/> ,单击“编辑”并在<true/>行下面添加以下两行:

    <key>SBParentalControlsPIN</key>
    <string>1234</string>

    所以文件中的文本如下所示:

    <key>SBParentalControlsEnabled</key>
    <true/>
    <key>SBParentalControlsPIN</key>
    <string>1234</string>
    ...other lines...

    How the Plist editor should look with the lines inserted
    Plist编辑器如何看待插入的行

  9. 保存修改后的662bc19b13aecef58a7e855d0316e4cf61e2642b文件,覆盖旧文件。

  10. 使用SHA-1哈希生成器生成 662bc19b13aecef58a7e855d0316e4cf61e2642b文件的另一个哈希值,并记下这一点。

  11. 获取Manifest.mbdb文件的安全备份副本,因为我们现在将编辑此文件。

  12. 在十六进制编辑器中打开Manifest.mbdb ,如HxD (免费)(或以十六进制模式运行的TextPad)。

    Editing the manifest with HxD (thanks for the tip, Taylor!)
    使用HxD编辑清单(感谢提示,泰勒!)

  13. 搜索您在步骤#4中执行的原始SHA1哈希(确保您在十六进制模式而非文本模式下搜索)。它说com.apple.springboard.plist或类似的 - 这是你正在寻找的正确的文本位。

  14. 现在是棘手的一点 - 您需要使用新的十六进制值(您在步骤#10中发现)覆盖旧的十六进制值。在大多数十六进制编辑器中,您可以通过键入旧值来执行此操作。

    例如,您可能会看到如下内容: 72 64 2E 70 6C 69 73 74 FF FF 00 14 38 F1 2D 84 14 0D 32 E3 6E DF D7 62 3F D1 7A 10 11 66 14 70

    假设您要更改的十六进制是38F12D84140D32E36EDF ,您需要将其更改为1234567890abcdef1234

    你要做的第一件事是找到旧的十六进制字符串的开头,然后你输入旧的十六进制代码,最后得到这样的结果: 72 64 2E 70 6C 69 73 74 FF FF 00 14 12 34 56 78 90 AB CD EF 12 34 D7 62 3F D1 7A 10 11 66 14 70

  15. 保存已编辑的Manifest.mbdb文件。

  16. 使用iTunes将备份恢复到iPhone - 如果在编辑后没有将它们直接保存到备份文件夹中,请确保在恢复之前用修改后的文件替换Manifest.mbdb662bc19b13aecef58a7e855d0316e4cf61e2642b文件。

  17. 手机在恢复结束后重新启动后,您现在可以使用PIN 1234访问家长控制。欢呼! 🎉

Thank you so much for this help... was able to successfully reset my restrictions password on my ipod touch with ios 6.16! This site is crucial for resetting IOS 6 restriction passcode. :mrgreen: :D

p.s. I advise others to leave Itunes open while changing the two files, because my Itunes re-backed up all the files when I opened it again to restore the edited backup. Trying to copy and paste the two edited files into the new backup caused Itunes' backup restore to fail... so I had to do the process all over again. It went a bit quicker the second time though. :)

p.p.s. If you use the HxD hex editor: after you make the two SHA-1 hashes and open the file that it states up there, click Search>Replace... and then copy the HEX value from the first hash, paste it in the "Search for:" box, copy the HEX value from the second hash, paste it in the "Replace with:" box, select "Hex-values" in the "Datatype:" row, and click the "Prompt on replace" checkbox . That should safely find and replace your hex values all at once. :)

Perfect! I hate Apple products, so thanks to some knowledgeable people and programs such as this by Apple Fans, I was able to fix my kids iPod so there are no more "Parental Restrictions" even though none were ever set. I even had to fight to get the iPod to take the backup I wanted it to (thanks to iTunes), nothing can ever be simple can it?

Great Software! Thank you so much!

Hi guys, just wanted to share with that i tried this and it worked out fine for me. THANK YOU VERY MUCH for sharing this. You saved my day!

Dude thank you!!! I was skeptical about tweaking code and stuff, but this worked like a charm! It reset the restrictions pass to 1234 and now I can turn them off! I am using Windows 8 btw and I found those files.

Obrigada!!!!!!!!! Paguei pelo programa mas valeu. Congui a senha de restrições!

It worked ! (On an 3GS running iOS 6.1.6) Fantastic! Well done and thank you for providing such clear, bomb-proof instructions.

thank you so much this was very helpful

Perfect!

thank sir

Hi Alexandra, You rock!! I easily rest my iPod Touch 5th generation's Restriction's PIN using your steps! Thanks a lot.

A long time ago I had setup a restriction code on my iPhone 4 to stop my younger brother from making in-app purchases. But now when I went to reset my device, I couldn't as I realised I had forgotten my restrictions code. I searched online everywhere but I didn't find a way of resetting this code. I had saved a local backup on my Mac and I came across this software. At first I was VERY sceptical of it working but the choice was between losing all my data and taking a leap of faith by paying for the home license. I went for the latter and am I glad! It's worked as promised, resetting my restrictions code to '1234' now I've turned the damn thing off - lesson learned! My phone is running iOS 7.0.6 as of now. If you are in a similar predicament, would definitely recommend!

This worked without issues. It took about 30 minutes. Thanks for the help. iPhone 5S ver.6.1.4 Firmware 3.04.25

Took a bit of fiddling, but got it to work with IOS6 on an iPod Touch. Three things I encountered...

  1. My iTunes was set to automatically back up when I plug in the device, so I ended up editing the files and then needing to do it all again after iTunes immediately overwrote the backup before I could restore from it. After disabling the auto-sync in the iTunes preferences, I was able to restore.

  2. While I've used TextPad for many years and have a full paid license, I could not get it to actually edit the manifest.mbdb file. TextPad kept complaining that the file was Read-Only, even though Windows Explorer did not agree. In the end, HxD-Hexeditor did the trick for me.

  3. Also, the SHA-1 hash generation site above kept giving me 503 errors. (1/20/2014) In the end, I used onlinemd5.com instead, and things were just fine.

Thanks for the help!

Awesome man! You saved my life. Thanks for the trick :D Smoothly worked!

I'm a thirteen year old girl, my parents put a child tracker on my phone and locked it with parental controls. This saved my life! Thanks so much!!! <3

THANKS!! Works also with IOS 7.03

Thanks SO MUCH!!!!!!!!!!!

AAAAAAWESOME!!! Worked perfectly on my iPhone 5 with iOS 7.0.2. Thanx a lot.

Holy crap, i am so amazed that this worked, even on ios 7.0.2, thank you very much, now i can download apps without my brother spending money again

Thank you soooo much!!! It perfectly works on my iPhone 5 with iOS 7.0.2. Thanks for sharing this precious method.

Thank you soooooooooooooooooo much!!!!

Great! Follow the steps and it's fixed forever. Thank you very much!

Thanks a lot for the instruction.

Worked perfectly on my iPhone 4S with brand new IOS7.

PS: I don't get why step 14 should be that tricky? just prepare the HEX-hash with blanks, copy and paste.

NOT SURE IF I AM JUST HAVING A BLONDE MOMENT AND NOT SEEING IT BUT IF I FOLLW THESE DIRECTIONS.... WILL I LOSE ANY OF MY STUFF THAT IS ON THE PHONE NOW OR WILL IT JUST CHANGE THE RESTRICTIONS CODE?

Don't worry, it'll effectively just change the code!

Amazing.. Worked like a charm. Did this from a Windows 7 box with the same tools for Windows. You did a fabulous job with this guide. My hat is off!

Thank you. Works great with iOS 7 as well!

Have you managed to figure out a workaround for IOS7 yet?

Thanks in advance!

YOU ROCK MAN!

THank you thank you SO MUCH! You're a lifesaver!! Thanks! WORKED LIKE A CHARM!

Ohh yeahh!!! After hours of searching! It worked!!! Thank you very much :D

It's a good thing I didn't spent Php 800.00 just to retrieve my passcode. Thanks again, dude!

For pass code

Thank u

I was able to finally get the program to work. Could not use SRIron browser which is basically Chrome. Had to check for my emailed key in IE and copied it to clipboard which automatically put it in the key field for me. Program is a lifesaver for anyone with an iPhone, iPad, or iPod. I have an iPad 3 and Vista. Worked great! But this time, I wrote down my passcodes so at least I have them somewhere. Nothing is better than the release from stress!

This post made my day. Kudos!

did any of you loose any data

this is amazing service, I am very pleased. thanks greatly

brooke

wow working good.. thank u very much.

Worked great for me! Thanks!

I need help every time I try to spring bored it won't change on the jailbreak plz help

This is awesome and it works . It took 20 minutes of time. I will Recommend these steps to everyone .

Thanks a lot.I had enabled the restrictions on while i installed iphone finder.The app suggests to enable it, so iphone finder can`t be uninstalled by other people.

way a go, just follow the tutorial above and it works!!!

Thanks yaar!!!hv a grt day!!just reset my restction passcode, its amazing!!!

After trying all the steps i can not restore the phone to the modified backup, itunes says the restore cant be made because there is not enough space free on the iphone.

@Paul: Hi, photos and videos take up the most space in the backup and on your phone. You can import media files from the device to your computer from time to time to save space and make your backup smaller. Photos and videos imported this way can always be synced back to the device. Good luck!

forgot my code

so after i did the "'Extract>Restrictions PIN' and reset your parental controls PIN", do i restore my iphone to that backup? or just unplug the phone and the PIN will be 1234?

Andrea: Hi, the last step is to restore the modified backup to your iPhone. The data from that backup restored means your PIN will be reset to "1234". Don't forget to keep a copy of your original backup in case something goes wrong! Good luck!

I was also succesful! I did in on a Mac (with Mountain Lion), and since I could not use the Mono framework to run the iPhone Backup Extractor, I needed to use some other tools. These were PlistEditPro and Hex Fiend. With those tools and your instruction, it worked on the first attempt! Thanks a lot!

Thanks perfect

IT's just amazing ,i cant believe that it's working prefect ,i was so worried ,even i'm not good programmer to understand these but still i did it and working well ..... Really appreciate ,Thank you

BIG TIME with this tutorial. Works more than well. Thanks a lot you guys.

Windows 8 & Surface Pro.

Thank you, worked perfectly!

On a first try I used WinVi32 as a hex editor and it didn't work: Couldn't restore the backup file (iTunes said it was damaged). Using Hex-Editor MX it worked well. :) Thank you very much for this great tutorial!

Just did this stuff, totally thought it wouldnt work, worked without a hitch, if when your doing it the part where your writing stuff under SBParentalControlsEnabled and it says you have unsuccesful attempts at unlocking it, just write in where he says to and it works fine.

Nice job. Got it on the first try.

After 27 failed attempts at trying to guess a code I don't remember setting, I found (and have bookmarked) this solution. Worked with no issues.

THANK YOU SO MUCH!!! This post is a lifesaver!!:D :D :D

Many thanks ! It is working perfectly !

Worked like a charm. THANK YOU!

Great piece of work! Thank you for sharing it to us folks who forget their passwords and don't have all that technical knowledge. Good that you are there!

I'm no computer wizard, and even I could follow your wonderful directions to reset a forgotten 'Restrictions Passcode' in my iPad. THANK YOU. The blogs and forums and Apple Support Communities are still not able to figure this out!

Many thanks, Nelson

Thank you so much. Unbelievable that I was incapable of remember 4 numbers, lol. Thank you, very straight forward and easy to do.
