आईओएस 15 डाउनग्रेड: इसे सुरक्षित और आसानी से कैसे करें

भाग 1. क्या आप iOS 15 डाउनग्रेड? के लिए अच्छी तरह से तैयार हैं

नवीनतम iOS अपडेट जारी किया गया है, लेकिन उपयोगकर्ता पहले से ही इसकी कुछ गड़बड़ियों के बारे में शिकायत कर रहे हैं। इन समस्याओं को दूर करने के लिए, आप iOS 15 डाउनग्रेड करने पर विचार कर सकते हैं। हालाँकि, आपको एक कदम पीछे हटना चाहिए और इसके नतीजों को समझना चाहिए। उदाहरण के लिए, डाउनग्रेड आपके फोन के सभी मौजूदा डेटा को मिटा सकता है जिसमें आपकी तस्वीरें, ऐप्स, संपर्क इत्यादि शामिल हैं। इसलिए, आईफोन पर आईओएस 15 अपडेट को पूर्ववत करने से पहले आवश्यक सावधानी बरतना महत्वपूर्ण है।

1.1 अपने डिवाइस का बैकअप लें

आईओएस 15 को पिछले स्थिर संस्करण में डाउनग्रेड करने से पहले यह सबसे महत्वपूर्ण बात है जिसका आपको ध्यान रखना चाहिए। जब हम किसी iOS डिवाइस को डाउनग्रेड करते हैं, तो हो सकता है कि वह उसमें संग्रहीत सभी डेटा को हटा दे। मीडिया फ़ाइलों से लेकर ऐप डेटा तक - इस प्रक्रिया में आप अपने फ़ोन की सभी मौजूदा सामग्री को खो सकते हैं। इसलिए, आईओएस 15 से स्थिर संस्करण में डाउनग्रेड करने का तरीका जानने का सबसे अच्छा तरीका है कि आप अपने फोन का बैकअप लें। इस तरह से आप डाउनग्रेड खत्म करने के बाद उसका बैकअप रिस्टोर करके अपने महत्वपूर्ण डेटा को आसानी से वापस पा सकते हैं।

  • 1आईट्यून्स का अपडेटेड वर्जन लॉन्च करें और आईओएस डिवाइस को इससे कनेक्ट करें।
  • 2इसके "सारांश" टैब पर जाएं और "बैकअप" टैब के अंतर्गत प्रासंगिक विकल्प ढूंढें।
  • 3अपने डिवाइस के बैकअप को बचाने के लिए "बैक अप नाउ" बटन पर क्लिक करें।
ध्यान देने योग्य बातें:
  • आईट्यून्स निचले संस्करण के उच्च संस्करण के बैकअप को पुनर्स्थापित नहीं कर सकता है। इसलिए आपको अपने डिवाइस को iOS 15 में अपग्रेड करने से पहले उसका बैकअप जरूर लेना चाहिए।
  • डेटा का पूर्वावलोकन करने और इसे चुनिंदा रूप से पुनर्स्थापित करने का कोई प्रावधान नहीं है।
  • बैकअप को पुनर्स्थापित करते समय iTunes आपके iPhone पर मौजूदा डेटा मिटा देता है।

1.2 आईओएस डाउनग्रेड के लिए समय सीमा को समझें

IOS संस्करण को डाउनग्रेड करने की पूरी प्रक्रिया समय के प्रति संवेदनशील है, जिसके बारे में बहुत सारे उपयोगकर्ताओं को जानकारी नहीं है। आइए इस बारे में विस्तार से बात करते हैं।

  • यदि आपके पास आईओएस बीटा संस्करण स्थापित है, तो आप किसी भी समय आईओएस बीटा को पिछले स्थिर संस्करण में डाउनग्रेड कर सकते हैं (आधिकारिक सार्वजनिक आईओएस संस्करण जारी होने तक)।
  • स्थिर सार्वजनिक iOS संस्करण के जारी होने के बाद, आपके पास अपने डिवाइस को पिछले मौजूदा iOS संस्करण में डाउनग्रेड करने के लिए केवल 14 दिन हैं।

1.3 iOS 15 से डाउनग्रेड करने के लिए सही संस्करण चुनें

आदर्श रूप से, आप केवल iOS 15 को केवल पिछले स्थिर संस्करण में डाउनग्रेड कर सकते हैं। उदाहरण के लिए, यदि आप iOS 15 को डाउनग्रेड करना चाहते हैं, तो आप केवल इसकी पिछली स्थिर रिलीज़ पर वापस जा सकते हैं, जिस पर Apple द्वारा हस्ताक्षर किए गए हैं। संगत फर्मवेयर उपलब्ध है या नहीं यह जांचने के लिए आप IPSW.me पर जा सकते हैं।

1.4 जानें कि किसी ऐसे संस्करण में डाउनग्रेड कैसे करें जो अब Apple द्वारा हस्ताक्षरित नहीं है (यदि आवश्यक हो)

जैसा कि आप जानते हैं, आईओएस 15 को डाउनग्रेड करने के लिए, आपको इसकी आधिकारिक रिलीज के 14 दिनों के भीतर आवश्यक कदम उठाने होंगे। साथ ही, उपयोगकर्ता केवल पिछले स्थिर संस्करण में वापस रोल कर सकते हैं। हालाँकि, यदि आपने 14-दिन की अवधि पार कर ली है और एक ऐसे संस्करण में डाउनग्रेड करना चाहते हैं जो अब Apple द्वारा हस्ताक्षरित नहीं है, तो आपको किसी तृतीय-पक्ष टूल का उपयोग करने की आवश्यकता है। TinyUmbrella या TaigOne Downgrader जैसे टूल की सहायता से, आप डिवाइस पर कोई भी समर्थित iOS संस्करण इंस्टॉल कर सकते हैं। वे Apple के हस्ताक्षर की नकल करते हैं, जिससे हम iDevices पर व्यक्तिगत फर्मवेयर (iOS संस्करण) स्थापित कर सकते हैं।

हालांकि पूरी प्रक्रिया काफी तकनीकी होगी, और यह सकारात्मक परिणाम नहीं दे सकता है। चूंकि ये तृतीय-पक्ष उपकरण Apple द्वारा समर्थित नहीं हैं, इसलिए आपको इसे करने के लिए अपने डिवाइस को जेलब्रेक करना होगा। यह अनुशंसित नहीं है क्योंकि यह आपके डिवाइस की वारंटी को प्रभावित करेगा और अब आपके पास आधिकारिक iOS रिलीज़ तक भी पहुंच नहीं होगी। इसके अलावा, यह आपके डिवाइस को अवांछित सुरक्षा खतरों के प्रति संवेदनशील बना देगा।

भाग 2. iOS 15 को सुरक्षित रूप से डाउनग्रेड कैसे करें?

अब जब आप iOS 15 को डाउनग्रेड करने के लिए सभी पूर्वापेक्षाओं से अवगत हैं, तो आप आसानी से अपनी आवश्यकताओं को पूरा कर सकते हैं। आदर्श रूप से, आप आईओएस 15 से डाउनग्रेड करने का तरीका जानने के लिए आईट्यून्स या किसी अन्य तृतीय-पक्ष टूल की सहायता ले सकते हैं। किसी भी स्थिति में, सुनिश्चित करें कि आपके डिवाइस का बैकअप पहले से रखा गया है। आपके लिए चीजों को आसान बनाने के लिए, हमने iOS 15 डाउनग्रेड करने के लिए दो समाधान प्रदान किए हैं।

2.1 आईओएस 15 को डाउनग्रेड करने के लिए एक-क्लिक समाधान

What are SHSH blobs for iPhone?

Both SHSH and SHSH2 blobs are referred to digital signatures deployed by Apple on respective IPSW files. This protects the authenticity of the IPSW files and only signed software would be installed on the device. When Apple releases a new iOS version, it stops signing the previous version. In this way, users need to upgrade to the latest public iOS version. This is where previously saved SHSH blobs are used to forge these signatures in order to downgrade our devices.

Part 4. iOS 15 Downgrading Troubleshooting

4.1 iOS 15 Downgrade Failed Many Times

This is one of the most common issues that users face while downgrading their iOS devices. The chances are that while downgrading your device, the process would stop in between unexpectedly.

It happens when we try to downgrade the device to an incompatible iOS version. A faulty internet connection or low free space on the device can also trigger it.

Quick Fixes:
  • Check the iOS version: Needless to say, if you are trying to downgrade your device to an iOS version it no longer supports, then you might face unwanted issues. Ideally, you should try to downgrade iOS 15 to a previous version and not any other existing one.
  • Have a stable internet connection: An inconsistent internet connection is another prominent cause for this error. It happens when the download of the iOS update is halted in between (due to a poor connection). Therefore, make sure that the device stays connected to a working and fast internet connection for a seamless downgrading. You can go to your phone’s WiFi settings to further diagnose this.

4.2 iOS Stuck in Recovery/DFU Mode/Apple Logo

While downgrading your device, your phone might get stuck in the recovery mode, Apple logo, or the DFU mode screen. The situation might seem a bit tedious, but you can try to resolve it by forcefully restarting your phone in most of the cases.

Downgrading from an unstable version, the download process of the firmware update has been halted in between, or any other firmware related issue.

Quick Fixes:
  • Forcefully restart your device: By applying the correct key combinations, we can forcefully restart an iOS device and resolve this issue. Since it resets the current power cycle of the device, it is also known as a soft reset. If you own an iPhone 6s or an older generation phone, then long press the Power and Home button for at least 10 seconds. Users with an iPhone 7 or iPhone 7 Plus can press the Power and the Volume Down button. Keep pressing them until your phone restarts. For iPhone 8 and newer versions, you need to quick-press the Volume Up button first. Let it go and quick-press the Volume Down button. Subsequently, hold the Side button and let it go once the phone restarts.
  • Connect it to iTunes: In case if your phone is stuck in recovery or DFU mode, and you haven’t connected it to iTunes, then do the same. In no time, iTunes will automatically detect that your device is in the recovery mode and display the following prompt. Just confirm your choice and restore your device to factory settings to fix this.

Quick Fixes:
  • Check whether your iPhone is jailbroken: Mostly, users get this error while performing iOS 15 downgrade on a jailbroken device. If your device is jailbroken, then you should not use iTunes to downgrade it. Instead, use a readily available tool like iFaith or TinyUmbrella to do the same.
  • Boot your iPhone in Recovery Mode: You can also take the assistance of iTunes and boot your device in the Recovery Mode to resolve this problem. To do this, just launch iTunes on your system and connect your phone to it. Now, using the correct key combinations, forcefully restart your device (already listed above).

An unsupported version of iTunes, corrupt IPSW file, or conflict with the device itself can result in this error.

Quick Fixes:
  • Check the IPSW file: Firstly, make sure that you have downloaded the correct IPSW file from a trusted source. Also, the IPSW file should be compatible with your iOS device else you might face this issue.
  • Disable Find my iPhone: Before you connect your device to iTunes, make sure that the Find my iPhone feature is disabled in it. To do this, go to its iCloud Settings > Find my iPhone and simply turn off this feature. This will not cause any conflict when you undo an iOS 15 update on iPhone.

Yes, you can downgrade iOS to a previous version signed by Apple. Users get 14 days after a public official release to do it. If you have upgraded your device to a version, then you can downgrade to a stable version easily (until 14 days after the release of its stable version).

There are all kinds of ways to undo an iOS 15 update on iPhone. If you want, you can take the assistance of iTunes to do the same. Though, to downgrade iOS 15 without losing data, consider using a more sophisticated tool like Dr.Fone - System Repair (iOS). In case if you have a jailbroken device, then you can even give tools like TinyUmbrella a go.

When we install an iOS version on the device, the Apple server asks for a digital signature to authenticate it. A signed IPSW file would have a verified signature issued by Apple, letting us upgrade/downgrade the device without any hassle. Therefore, if an IPSW file is not signed by Apple, then it will not be recognized by the server and the upgrading/downgrading process won’t be completed.

There are all kinds of SHSH dumps and readily available third-party tools that can help us force Apple’s signature and create SHSH blobs even after Apple stops signing them. Though, you should know that Apple might revoke the authentication of such SHSH blobs anytime. To do this, you need to have a jailbroken device and use a dedicated tool like iFaith or FutureRestore.

The Apple Software Program lets us test the releases of iOS before the public availability. You can join or leave the program anytime you want without spending anything. If you want to leave it, then go to the Unenroll section of the website.

Ideally, you can’t downgrade your device to an unsigned iOS version. This is because the Apple server won’t authenticate your downloading request without a valid SHSH blob. That is why users take the assistance of a previously saved SHSH blob to do the same. You can also use a third-party downgrading tool to do it as well.

After downgrading an iOS update, you might find an existing software profile on your device storage. To remove this, just go to your device’s Settings > General > Profile and select the iOS profile from here. Tap on the “Delete Profile” option and confirm your choice to remove it.

You can restore a previously stored SHSH blob from your device or forge Apple’s signature. There are a few third-party tools like FutureRestore that can help you do the same. You can also choose to dump your SHSH blobs in order to use them afterward. Though, in most of the cases, users have to jailbreak their device in order to do it.
