Fix Bootloop On Android & Learn The Causes Of bootloop

Bootloop is a nightmare for all Android device owners. When experiencing a bootloop, the device will continue to spin on the boot screen and cannot enter the system. As a result, the device will not be able to be used again.

There are many ways to overcome bootloop that you can apply. However, how to overcome this bootloop is quite complicated because each device will have a different way from other devices. In addition, this bootloop problem also usually ends with the deletion of data on the Android device.

Now, this time will review several ways to overcome bootloop on Android devices. However, the method described here is only a general method and not a specific method for every Android device. First, let’s discuss the various causes.

Bootloop Cause

There is no smoke without fire. Yes, bootloop can not happen suddenly without a specific cause. This bootloop usually occurs because we do various things that intersect with the Android system. So here are some of the causes of the bootloop:

  • Flashing custom ROM

Bootloop problems often occur after we flash a new custom ROM. This is usually because there are dalvik-cavhe or old data that has not been deleted so that they are used by the new system. A corrupted custom ROM package can also cause a bootloop after you install it.

  • Instal mod

Bootloop usually also occurs after we install mods for the Android system. This problem arises because the installed mod is not compatible with the ROM we are using. In addition, mods that are not well structured can also be the cause of this bootloop.

  • Wrong set of permissions

Android relies heavily on correct system permissions. If you set the permissions of a system file incorrectly, it can lead to a bootloop. Therefore, be careful before giving permissions to a file.

  • Restore system backup

Performing a file restore related to the system also has the potential to cause a bootloop. Just like the first cause, this problem is also caused by the old dalvik-cache that has not been completely deleted.


How to Overcome Bootloop

After knowing the various things that cause it, now let’s discuss how to overcome the bootloop. Make sure you know the cause so you can treat it with the right method.

  • Clear dalvik-cache

If the bootloop occurs after you flash a new custom ROM or after doing a restore backup, then you can try this first method. This method will clear the old dalvik-cache so the system will replace it with the new one.

First of all, turn off the Android device completely by removing the battery and then let it sit for 2 to 3 minutes. If the battery is embedded and cannot be removed, then press the power button for a few minutes until the device turns off completely.

Then restart the device and go to recovery (CWM, TWRP, and the like). The entry method is different for each device, some are by pressing the volume down button, some are pressing the home button, and so on. Please adjust it with the device you have.

In the recovery you can use the volume buttons, home button, and power button to navigate. But again the function will be different on each device. Now after entering recovery, please follow these steps:

  1. Select the Advanced menu
  2. Select the “Wipe dalvik-cache” option
  3. Then open the “Mounts & Storage” menu
  4. Select the “Wipe/cache” option
  5. Reboot
  • Clear data

If after following the steps above the bootloop issue is still not resolved, then you can also try wiping the data. But before that you have to do a backup first to save the data. Here are the steps:

  1. Enter Recovery
  2. Select the “Backup & Restore” menu
  3. Select “backup”
  4. Then open the “Mounts & Storage” menu
  5. Select “Wipe /data”
  6. Select “Wipe/cache”
  7. Reboot
  • Flash the new ROM

If the two methods above have not been able to solve the bootloop problem, then most likely the custom ROM you installed is damaged or not compatible with your Android device. To fix this, you will need to download and install a new custom ROM. The method:

  1. Enter recovery
  2. Select “Install zip”
  3. Find the custom ROM you just downloaded and install it
  4. Reboot

If you don’t want to install a new custom ROM, you can also install the stock ROM on your device. This method varies depending on the device you are using. For example, Sony devices can use the PC Companion application, Samsung with KIES, and the like.

  • Permission correction

If the bootloop problem is caused by an error giving permissions, then the fix is ​​quite easy. Here are the steps as quoted from XDA:

  1. Enter Recovery
  2. Open the Advanced menu
  3. Select the “Fix permissions” option
  4. Reboot

So, those are some of the causes and ways to overcome bootloop that can be applied to your Android device. Remember, the method above is only an overview so not all of them can be applied to every Android device. Please visit the forum or FB group of each device for a more specific way.
