We all know what we love the most on the Android system. Yes, of course I am talking about updates, whether it is about an OTA, a new security patch or why not even about a new custom ROM software. Managing updates and always trying what’s new on Google Play is exciting as long as our smartphone can provide enough power in order to experience a smooth and a stable Android OS. Well, if you want to learn how to smartly manage all these update operations on your own Samsung Galaxy On7 read all the lines from this dedicated step by step guide.

As already mentioned, there are more ways in which you can update your Samsung Galaxy On7: you can wait until a new OTA is being rolled out, you can manually flash the stock / official Android firmware, you can downgrade your phone back to a previous Android built or you can use a custom ROM software such as CyanogenMod, AOKP or Paranoid Android. It is just up to you as all these flashing procedures can be easily applied on your phone – and if you don’t know how to apply a certain update process, don’t panic as you have it all explained below.

As you will see, each update process comes with its own advantages and downsides. It is important to choose only what suit your needs. So, before choosing to perform a certain process, read everything – you have it divided into separate sections so it will be easy for you to understand how each update operation works on the Samsung Galaxy On7. Don’t forget to review the pre requisites, when that’s implied, as without these preparation tasks you won’t be able to safely update your Galaxy On7.

Managing OTAs

What to do when a new OTA is released

As you might know Samsung is periodically releasing security patches. These are small updates that come to secure the Android system. Also, these types of updates usually comes pre loaded with stability improvements and with bug fixes, which means that you shouldn’t skip the implied software. On the other hand, from time to time Google and your OEM will provide a major update which will introduce new features, app and capabilities. In both situations you have to ensure that your Galaxy On7 isn’t rooted and that the stock Android system is already running on your phone.

Otherwise, you won’t be able to receive the Android notification – in that situation you must wait until the full firmware package is released in order to install it manually through Odin (that process will be explained during the following section of this step by step guide), or you first have to go back to stock.

Moreover, the OTAs are usually offered gradually, in phases and in limited markets only. As a conclusion, not all the Galaxy On7 can receive the Android notification at the same time. Thus, some users will have to wait more than others. But, you can try a little trick: you can force down the OTA.

How to Force Down a new Notification

Once more, first you must ensure that your phone is powered by the official Android OS; of course, its system must be locked. Then, you have to follow:

  1. Power on your smartphone.
  2. Enable a WiFi connection.
  3. Tap on Menu and then select Settings.
  4. Go to About phone and select Software version.
  5. There you should be able to search for a new update.
  6. Do so; if an OTA is available you will be prompted with the notification.
  7. In that case, start by charging your device.
  8. Then, just follow on screen prompts and resume the installation process.

Manually update / downgrade with official / stock ROMs

As you could notice, if waiting for the OTA roll out is just not your thing, or if the root access is standing on your way, you will have to consider in manually installing the stock Android OS. This is a complex operation that comes with great advantages and which can be completed with ease, even by newbies.

From the start you should know that it is an official operation – you will use official versions of the Android OS. So, you won’t lose your Galaxy On7 warranty and you won’t have to use risky and complex tools in order to apply the steps from this update section.

The same steps can be used for manually updating or downgrading your phone. So, you can either go back to a previous built of Android or you can use the full firmware package in order to skip the OTA wait. Or, you can use the same process in order to revoke root access and for restoring your On7 back to its intial state.

As a result, you can update to an official software even when your Galaxy On7 is rooted and, most important, you can manually address software related issues. Since you will manage to restore your device back to stock by re-flashing the Android firmware you will also get rid of malicious apps, malware, inapropiate tools and so on. Thus, you can choose to use this update process for fixing a soft bricked Samsung Galaxy On7 – basically, you can address problems such as boot loops, lags, bugs, force close errors, battery drain, heating issues, screen freeze, signal strength problems, total blackouts and so on.

Your data might be in danger – while applying the update your personal info, accounts and files might get corrupted. So, it is recommended to backup everything you might need afterwards – including the Samsung Galaxy On7 EFS folder, internet settings and IMEI / NVRAM data. In that respect now it will be the perfect time to learn how to sync your data with your account, what backup and restore apps to download from Google Play and which other dedicated cloud storage platforms to use on your phone.

Being a manual update / downgrade operation, some pre requisites are now required:

  • A computer must be near you: on this computer you will download the Galaxy On7 stock / official Android OS.
  • Also, on the PC you must download and install the Galaxy On7 USB drivers (you can do it through Samsung KIES) and you must install Odin, the program through which you will complete the flashing process.
  • On your smartphone you have to become a developer: tap 7 times on Built Number until you get the ‘You are a developer’ message.
  • Also, on your phone check the USB Debugging option – you can do so with ease by accessing the following path: “menu – settings – developer options”.
  • Check the battery icon on your On7. If the power is lower than 50%, plug in the charger – in this way you can avoid further unpleasant situations.

You are now ready to learn how to use Odin for manually updating or downgrading your Samsung Galaxy On7 with stock Android OS:

  1. Download and install Odin on your computer; remember to install your phone’s USB drivers too.
  2. Then, download the firmware you want to flash – you can use the Samsung official web site or the SamMobile database.
  3. Reboot your Galaxy On7 into download mode.
  4. Run Odin on your computer.
  5. Establish a connection between your devices.
  6. From Odin tap on the AP button and load the software package.
  7. Don’t check the Re Partition and the Auto Reboot options.
  8. Click on Start.
  9. In the end the “pass” message will be displayed and the ID:COM field will be turned green – that’s the sign you need: you can unplug the USB cord and reboot your Galaxy On7.

Updating your Galaxy On7 with a custom ROM

When a custom ROM is involved, we must change the subject a little bit. You see, a custom ROM is an unofficial port of the stock Android OS, which means that this update will be developed not by your OEM but by third party devs. So, it is an unofficial update which will make the update process also unofficial. As a result, if you choose to install a custom ROM (like CyanogenMod, AOKP or Paranoid Android) you will lose the warranty of your smartphone.

However, using such a firmware is just great. If the ROM is stable and smooth, your Samsung Galaxy On7 should run better and faster than before. Custom ROMs are usually bringing features, apps and capabilities that cannot be found on the default Android system. Through these precise custom features you can afterwards customize, optimize and upgrade your device. Your options are just endless as you can do everything you want: upgrade the battery life, overclock or undervolt the CPU frequencies, remove bloatware and lot more.

Anyway, since it is a complex operation you can install a custom ROM only if you first root your Samsung branded device and only if a custom recovery image is already running on your phone. The root access will unlock the internal system and through the custom recovery you will resume the flashing operation.

Making a backup is a must. In this situation you will definitely lose everything – the ROM will work only if you first hard reset your Galaxy On7 and only if you clear app data cache. Thus, save everything you might want to restore afterwards: images, videos, audio files, market apps, calendar info, saved passwords, contacts, call logs, texts and so on. Along with the usual backup you should also make a Nandroid backup operation – this process will save the current Android OS that powers your Samsung Galaxy On7, so if the new ROM will not run properly you will be able to use the Nandroid backup file in order to go back to stock quick and easy.

Then, the pre requisites which were explained above must be applied here too – make sure a computer is there; become a developer and check the USB Debugging option on your phone; charge your smartphone before doing anything else. Then, just follow:

  1. On your computer download the custom ROM you want to add on your Samsung Galaxy On7 – you can get great ROMs from xda-developers.com.
  2. Optional: download compatible Google Apps if that’s required.
  3. First, save these files on your computer; then connect your device with your computer with the help of the USB cable and transfer the files on your phone. When done, unplug the USB cord.
  4. Put your Galaxy On7 into recovery mode.
  5. The first thing to do from recovery is the wipe; so select: “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
  6. Then, return to the main menu of recovery; from there select “install zip from SD card” followed by “choose zip from SD card”.
  7. Pick the update file and the Google Apps package.
  8. Follow on screen prompts and resume the installation process.
  9. When the ROM is installed, from recovery select “Reboot system now”.


These are the update operations that can be performed on the Samsung Galaxy On7. The steps explained above can be safely completed even by an inexperienced user as you don’t have to use complex or risky programs and tools.
