Lenovo A390t has been stuck in android after being rooted by me and is upgrading

Troubleshooting Steps:

1. If the phone keeps displaying"Android is being upgraded"If you can't turn it on, it may be that the mobile phone software is installed too much, and the system software conflicts. You can try to enter the recovery of Lenovo A390T.

2. After flashing, enter Recovery Shuangqing, and then the phone will be displayed all the time"Android is being upgraded"And it can't be turned on. This is usually installed in the user's data partition by the Google framework, and the Google-related files of the user's partition are emptied after double clearing. So it will always be displayed and can't turn on,At this time, you can re-use the third-party recovery card to swipe the original package,Or enter the Lenovo A390T flash package to find the card and swipe the package,It's also a good repair system。

3. The mobile phone will prompt every time it is turned on"Android is being upgraded"You need to wait to enter the interface to use,This can be caused by installing the Google framework and then deleting,Here you can use the re manager to enter the data dalvik-cache directory,And then create a new folder,Name it clear-done-ics (if there is a clear-done-ics file,Delete it directly and then create a new folder),You don't need to change any permissions,Just create a folder。

Dear Lenovo users, Hello.

According to your description, it may be that the system cannot operate normally after rooting, it is recommended that you take your phone to Lenovo's mobile phone service center for testing and repair;

The most respected Lenovo mobile phone judge hail household, hello!

Sorry for the inconvenience caused to the normal use of your mobile phone.

Boot prompt upgrade, it may be that there is a related system software automatically updated and upgraded before the last system shutdown, you can use it normally after waiting patiently, it is recommended that you observe and use.

However, problems such as "automatic shutdown after full charge" and "charging does not turn off after resetting factory settings" did not occur with the A390T used in personal testing.

According to the description, if the system is abnormal, it may be due to some third-party software conflicts caused by the system abnormality, it is recommended that you try to back up the important data of the body, and then restore the factory settings of the phone to see if it can be improved.

If there are some previous operations involving the system level, such as flashing third-party firmware or root to obtain permissions, you need to re-flash the machine to restore the use of the system.

If you have flashing experience, want to restore the system by yourself, and are willing to bear the possible risks, I personally recommend that you go to the Lenovo official Lewen bar firmware area**The official firmware of your mobile phone.

The official firmware is the offline flash firmware in the shutdown state, and the built-in detailed tutorial is required, please operate carefully).

If it cannot be effectively solved, we recommend that you take the time to go to your local Lenovo after-sales service center and let the engineer help test and solve the problem. You can log in to the official website to check the address.

If you can't upgrade the system, it is recommended that you go to the "System Settings - Storage" of your phone to check whether the default software installation location - "Internal Storage" has enough space left. You can try to uninstall some of the software, or go to your phone's "System Settings - Applications - Already" to move some of the removable software to the built-in memory card of the body, and then try to install it.

In addition, if the system upgrade is repeatedly prompted, it should be that the system is abnormal. You can also back up your data and try to use it by restoring it to factory settings.

It's not okay to only install re.,You have to root.,Give re advanced permissions.,It is recommended to use the root master for one-click root! Then go to the system app to delete the apk files that start with up and so on, of course, you must confirm it before deleting it, otherwise it is easy to become a small brick!

Can't delete your phone may not be rooted!

The following answers are from:

1、Use the RE manager to enter the system framework2、Delete the following two files: Remind LZ that there will be a RE manager after flashing, if you want to flash the machine, there will be "one-click root".

Why delete the system files, it's not good if the system crashes, or upgrade honestly, or don't restart it and keep it powered.

You can turn off that upgrade. It's a good idea to upgrade.

When the Android system is booted, it stops in the Android is being optimized, and the interface indicates that the system has not been able to start, it may be that the mobile phone **OTA has not been automatically double-cleared after upgrading, resulting in confusion in the system cache, or the system must have been deleted, or a different version of the APK has been replaced, resulting in failure to boot.

It is recommended to enter the recovery mode to perform the double-clear wipe operation.

Recovery mode refers to a mode that can modify the data or system inside the Android machine (similar to Windows PE or DOS). In this mode, we can flash in a new Android system, or backup or upgrade the existing system, or we can restore the factory settings here.

Ways to get into recovery:

1. After the phone is completely turned off, press and hold the volume button + power button to enter the bootloader interface;

2. Press the volume button to move the cursor to the recovery line;

3. Press the power button, and then the phone will automatically reboot into recovery mode.

The volume button is the cursor selection key, which can be used to move the cursor, and the power button is the confirmation key.

The steps for dual wipe are as follows:

In recovery mode, use the volume down button to select Wipe Data Factory Reset.

Press the home button to run the wipe data factory reset command, then use the volume down button to select yes --delete all user data and press the home button to execute the command.

After the yes --delete all user data command is executed, the execution starts.

Press the volume down button to select the wipe cache partition command and press the home button to execute.

After the wipe cache partition command is executed, select yes --wipe cache in the volume down button and press the home button to execute the command.

After the yes --wipe cache command is executed, the wipe cache partition is also executed.

After the wipe data factory reset and wipe cache partition are successfully executed, select reboot system now and reboot the system.

Hello, according to the situation you described, it is recommended that you back up your data first and restore it to factory settings. If you can enter the system normally, you can find the factory reset option in the system settings.

If you are unable to enter the system, perform the following "Double Wipe.""Operate by pressing and holding the "Power button + volume plus or minus" at the same time in the shutdown state"Enter the recovery mode and execute "wipe data." respectivelyand "wipe cache...., restart your phone.

You open your phone's settings, turn off your phone's automatic updates, and try it. In this case, it seems that the phone is updating automatically.
