How to downgrade to an old version of Android

In general, it’s always best to keep your devices up to date. But unfortunately, updates can sometimes break software, change features in unwanted ways, or introduce bugs that the manufacturer may not fix.

If this happens, you should consider rolling back any updates that cause severe bugs in your phone. Going back to a previous version of Android is generally not recommended, but it’s not impossible. Here we teach you how to downgrade to the old version of Android .

Before downgrading the device

Dungrid is not officially supported by manufacturers. It’s not easy to do, it may void your warranty, and you could potentially brick your device. You should not attempt this unless you have experience modifying your device’s operating system.

Whether you can root your device at all depends on unlocking the bootloader. Google or OnePlus devices can be easily unlocked, while Huawei, Samsung or Nokia devices can be difficult or completely impossible to unlock.

You’ll need to research your device, and if you’re buying it from a carrier, the process can be more complicated. Some carriers require you to get an unlock code from them first or don’t allow unlocking the bootloader at all.

Finally, unlocking the bootloader will erase all your data and wipe your internal storage. So, before you start, make sure you have backed up all your data!

Things you need before downgrading your device

In this part of how to downgrade to the old version of Android, we will examine the things you must do before downgrading. After you’ve backed up all your data, you’ll need to download an Android factory image of the version you want to go back to, and it needs to be one designed specifically for your device. Google provides a list of factory images to Pixel users. For other phone manufacturers, you need to find an official factory image for your device.

If you can’t find factory images on the manufacturer’s website, a great place to look for them is on the XDA forums .

Also, to use ADB and fastboot tools, you must download and install SDK Platform Tools . If you haven’t used them before, you can check out our guide to ADB and fastboot to familiarize yourself with them. Finally, you need to connect your phone to your PC via USB, so make sure you have a good quality cable (preferably if your mobile phone has an original cable).

How to root your Android phone

In the next part , how to downgrade to the old version of Android, we will check how to downgrade the phone. We are using Pixel phone for demonstration. This process should work on most rootable phones, but every device is different. Some follow a different set of instructions or require different tools. Before proceeding, check if this is the case for your device. The XDA forums we mentioned are a good place to look for this information.

Our instructions are also designed for Windows PCs, although the steps are largely the same if you’re also using macOS or Linux.

Step 1: Enable USB Debugging

The first thing you need to do is go to the settings , find  the About phone section and then tap on the Build number until you get a message that says You are now a developer! .

Next, go to Developer Options and enable USB debugging and OEM unlocking .

Step 2: Connect your phone to your computer

Connect your phone to your PC with a USB cable.

On your PC, navigate to the location where the SDK Platform Tools folder is saved and place the Android factory image you downloaded there. Factory images usually come in ZIP files that contain IMG files. Unzip the factory image right there in the Platform Tools folder.

Now, while still in the Platform Tools folder, hold Shift and right-click inside the window, then select Open PowerShell window here .

How to downgrade to an old version of Android

In the PowerShell window that opens, type adb devices to check if your phone is detected. If so, you should see its serial number listed. If not, use a different USB cable.

Now you need to boot your device in fastboot mode. To do this, type the following command in PowerShell:

adb reboot bootloader

Step 3: Unlock Bootloader

Once your device is in fastboot mode, now it’s time to unlock your phone’s bootloader. This is a very important step because without unlocking the bootloader, you cannot install a previous version of Android on your phone.

Depending on your device, type fastboot oem unlock and if that doesn’t work, type fastboot flashing unlock instead . If all goes well, you should see a confirmation on your device that the bootloader is now unlocked.

Warning: This step will wipe your device.

Step 4: Install the old version of Android

Some manufacturers include a “flash-all” script as part of the loaded factory image that will automatically flash everything for you. If so, the script should be in the SDK Platform Tools folder along with the IMG files you extracted.

Now double click on the flash-all.bat script. A box should appear showing you the flashing process as it happens. Please do not unplug your phone during this process!

If you don’t see the flash script for everything, you’ll need to flash everything manually. To do this, type the following commands in order:

How to downgrade to an old version of Android

Now your phone should restart. If everything went well, you should now be running a downgraded version of Android. You need to restart your phone from scratch.

Alternatives to Dungrade to Consider

Since unlocking your device’s bootloader will wipe all your data, you may want to consider doing a factory reset instead .

It’s much less complicated and risky than downgrading, and any bugs or performance issues you may have encountered will often disappear after a factory reset. Plus, you can still enjoy all the features of the new Android version.

If you don’t want to downgrade to an older version of Android, you can install a custom ROM. Custom ROMs come with improvements over your device’s official firmware, and developers sometimes keep older versions updated with security fixes.

If your phone manufacturer doesn’t provide you with images of older Android software, this is an alternative worth checking out. LineageOS is one of the best custom Android ROMs and is worth checking out.

Roll back your Android update

While a factory reset is usually enough to fix problems, if the only option available is to go back to a previous version, now you know how to do it.

Remember that the method we described may not work with your device. This process always carries the risk of damaging your phone, so back up all your data first!

Unveiling of OpenAI new artificial intelligence capabilities

OpenAI

OpenAI claims that its free GPT-4o model can talk, laugh, sing, and see like a human. The company is also releasing a desktop version of ChatGPT’s large language model.

 Unveiling of OpenAI new artificial intelligence capabilities

Yesterday, OpenAI introduced the GPT-4o artificial intelligence model, which is a completely new model of the company’s artificial intelligence, which according to OpenAI is a step closer to a much more natural human-computer interaction.
This new model accepts any combination of text, audio, and image as input and can produce output in all three formats. It can also detect emotions, allow the user to interrupt it mid-speech, and respond almost as quickly as a human during a conversation.
In the live broadcast of the introduction of this new model, Meera Moratti, Chief Technology Officer of OpenAI, said: “The special thing about GPT-4o is that GPT-4 level intelligence has been made available to everyone, including our free users. This is the first time we’ve taken a big step forward in ease of use.
During the unveiling of the model, OpenAI demonstrated the GPT-4o, which translates live between English and Italian, with its intuitive ability to help a researcher solve a linear equation on paper in an instant, just by listening to The breaths of an OpenAI executive give him advice on deep breathing.
The letter “o” in the name of the GPT-4o model stands for the word “Omni”, which is a reference to the multifaceted capabilities of this model.
OpenAI said that GPT-4o is trained with text, images, and audio, meaning all input and output is processed by a neural network. This differs from the company’s previous models, including the GPT-3.5 and GPT-4, which allowed users to ask questions just by speaking, but then converted the speech to text. This would cause tone and emotion to be lost and interactions to slow down.
OpenAI will make this new model available for free to everyone, including ChatGPT users, over the next few weeks, and will also initially release a desktop version of ChatGPT for Apple computers (Mac) for users who have purchased a subscription, starting today. They will have access to it. The introduction of the new OpenAI model took place one day before the Google I/O event, which is the company’s annual developer conference.
OpenAI
It should be noted that shortly after OpenAI introduced GPT-4o, Google also presented a version of its artificial intelligence known as Gemini with similar capabilities.
While the GPT-4 model excelled at tasks related to image and text analysis, the GPT-4o model integrates speech processing and expands its range of capabilities.

Natural human-computer interaction

According to OpenAI, the GPT-4o model is a step towards a much more natural human-computer interaction that accepts any combination of text, audio, and image as input and produces any combination of text, audio and image.
This model can respond to voice inputs in less than 232 milliseconds, with an average speed of 320 milliseconds, which is similar to the response time of humans in a conversation.
This model matches the performance of the GPT-4 Turbo model on English text and code with a significant improvement in converting text to non-English languages while being much faster and 50% cheaper via application programming interface (API). The GPT-4o model is especially better in visual and audio understanding compared to existing models.

What exactly does the introduction of this model mean for users?

The GPT-4o model significantly enhances the experience of ChatGPT, OpenAI’s wildly popular AI chatbot. Users can now interact with ChatGPT like a personal assistant, ask it questions and even hang it up wherever they want.
Additionally, as mentioned, OpenAI is introducing a desktop version of ChatGPT along with a revamped user interface.
“We recognize the increasing complexity of these models, but our goal is to make the interaction experience more intuitive and seamless,” Moratti emphasized. We want users to focus on working with GPT instead of being distracted by the UI. Our new model can reason text, audio, and video in real-time. This model is versatile, fun to work with, and a step toward a much more natural form of human-computer interaction, and even human-computer-computer interaction.
The GPT-4o model has also been extensively reviewed by more than 70 experts in areas such as social psychology, bias and fairness, and misinformation to identify risks introduced or enhanced by the newly added methods. OpenAI has used these learnings to develop safety interventions to improve the safety of interacting with GPT-4o. The members of the OpenAI team demonstrated their audio skills during the public presentation of this new model. A researcher named Mark Chen emphasized its ability to gauge emotions and noted its adaptability to user interruptions.
Chen demonstrated the model’s versatility by requesting a bedtime story in a variety of tones, from dramatic to robotic, and even had it read to him. As mentioned, this new model is available for free to all ChatGPT users. Until now, GPT-4 class models were only available to people who paid a monthly subscription.
“This is important to us because we want to make great AI tools available to everyone,” said OpenAI CEO Sam Altman.

Strong market for generative artificial intelligence

OpenAI is leading the way in productive AI alongside Microsoft and Google, as companies across sectors rush to integrate AI-powered chatbots into their services to stay competitive.
For example, Anthropic, a competitor of OpenAI, recently unveiled its first corporate proposal to Apple to provide a free program for iPhones.
“We recognize that GPT-4o audio presentations present new risks,” OpenAI said in a statement. Today we’re publicly releasing text and image inputs and text outputs, and in the coming weeks and months, we’ll be working on the technical infrastructure, post-training usability, and security necessary to release other methods. For example, at startup, audio outputs are limited to a set of predefined sounds and adhere to our existing security policies. We will share more details about the full range of GPT-4o methods in a future system.
OpenAI
According to the report, the generative AI market saw a staggering $29.1 billion in investment across nearly 700 deals in 2023, up more than 260 percent from the previous year. Predictions indicate that the yield of this market will exceed one trillion dollars in the next decade. However, there are concerns about the rapid deployment of untested services by academics and ethicists who are troubled by the technology’s potential to perpetuate prejudice.
Since launching in November 2022, ChatGPT’s chatbot has broken records as the fastest-growing user base in history, with nearly 100 million weekly active users. OpenAI reports that more than 92% of the world’s top 500 companies use it.
At the presentation event last night, Moratti answered some questions from the audience and when he spoke in fluent Italian and the artificial intelligence translated his words into English, the hall was filled with excitement.
There is more. This means the next time you take a selfie, OpenAI’s artificial intelligence can assess your exact emotions. All you have to do is select a selfie and ask ChatGPT to tell you how you feel.
It should be said that OpenAI employees were so happy that ChatGPT asked them why they were so happy!
