How to update Android firmware on Lenovo devices

BIOS is a set of programs that are stored in the motherboard memory. They serve for the correct interaction of all components and connected devices. The BIOS version determines how correctly the equipment will function. From time to time, motherboard developers release updates that fix problems or add new features. Next, we will talk about how to install the latest BIOS for Lenovo laptops.


Lenovo is a corporation whose devices based on Android OS have gained a strong position in the gadget market. The main advantage of devices from a renowned manufacturer and at the same time their main disadvantage is diversity. On the one hand, the consumer can easily choose a universal gadget, on the other hand, Lenovo does not always release firmware updates for all devices. As a result, users have to do without optimization for a long time. It is for this reason that in this post we will look at the question of how to update Android on Lenovo.

Why update firmware?

A firmware update makes useful adjustments not only in terms of design, but also in overall operating efficiency. Therefore, the owner must systematically check his device for possible new software versions.

The main positive effects of updating the system include:

  • productivity increase;
  • increasing the life of one battery charge;
  • improving work stability.

It should be noted that each manufacturer of multifunctional devices on bare Android tries to add its own launcher, allowing for more efficient use of the device’s capabilities. Thus, updates bring additional comfort during use.

As for the firmware itself, today on the market you will find assemblies of both licensed and custom versions. It is better to give preference to the former, as they ensure more stable operation of the device.

What is tvsu.exe?

tvsu.exe is an executable file that is part of the Lenovo System Update program developed by Lenovo . The software is usually about 13.4 MB in size.

The .exe file name extension represents the executable file. In some cases, executable files can damage your computer. Please read the following to decide for yourself whether the tvsu.exe file on your computer is a virus or Trojan horse that you should delete, or whether it is a valid Windows operating system file or a reliable application.

Updating Android OS on Lenovo devices

Initially, you need to make sure that this process is necessary. With Lenovo brand phones, the procedure most often involves the use of custom versions of software, so any manipulations with the operating system will already carry the risk of breakdown and future failures.

You also first need to enlist the help of competent technicians or people who have already managed to update the Android system on a Lenovo phone. You can provide yourself with such support through the interactive service.

Here you can find firmware directly for your multifunctional device, including both official versions and assemblies of individual individual developers.

Special attention should be paid to the procedure for preparing for firmware. For everything to be successful, the gadget must be charged at least 50%.

If you are using your computer to update the OS, make sure that the USB cable you are using is in good working order. Otherwise, a failure may occur right at the time of flashing the firmware, and the device will become bricked.

Update directly over the air

The easiest way to update the Android system on Lenovo is to use the built-in utility, which will automatically download the appropriate archive with the new firmware from an official source. Every device user can use this utility, and it does not require root rights.

Just go to the gadget settings, go to the “Help” section, find the “Phone information” item and tap on the “Search for updates” column. Depending on the device model and the version of the already installed firmware, the path to launching the utility may differ.

If the search for the firmware is successful, all you have to do is agree to the installation and wait a few minutes while the new files are downloaded, unpacked and installed. It should be noted that sometimes firmware can take up 100 megabytes or more, which is why it is better to use available Wi-Fi networks to save mobile traffic when uploading to the device.

Update using the UpdateTool L3 utility

If you were unable to receive an update over the air, you should use another, quite practical firmware method - the UpdateTool L3 program.

This utility was released specifically for updating Lenovo Android devices. You will need to download this program and install it on your computer.

You must also upload the firmware file in .nb0 format to the PC. The utility only works with it.

Now all that remains is to carry out the usual installation procedure. You connect the device to the computer via a USB cable, having previously enabled USB debugging, and launch the program, where you will be asked to select the firmware file and firmware method.

This program can flash a Lenovo device either with or without deleting the user’s personal data.

Computer Driver Maintenance

Lenovo Notebook errors are often caused by viruses, outdated and corrupted device drivers. When the operating system your device depends on receives an update, drivers may suddenly stop working with it. The good news is that the Laptop system driver can always be modified to solve the laptop dilemma.

It is often difficult to find the correct solution for Lenovo Notebook hardware error by visiting the Lenovo website. Even experienced, tech-savvy people with a good habit of updating Lenovo Notebook device drivers can still find the entire installation and update process time-consuming and annoying. Incorrect hardware drivers can lead to more serious problems than just a faulty installation.

To keep up with all the new updates needed, we suggest going with a driver update program. These update applications keep the required drivers up to date and create a backup of your current drivers before installing new ones. Maintaining a driver backup file is a great feature that allows you to revert any driver back to a previous version in case something catastrophic happens.

The concept of operating system backup

If the user has chosen a custom operating system to flash the device, he must be prepared for a negative result of the experiment, that is, for failures and systematic freezes. The reason for such unpleasant moments is the shortcomings on the part of home-grown specialists.

Before updating, you need to make a copy of the system, which, although potentially outdated, works stably. Today there are many additional programs for this. These include: Helium App Sync and Backup, Holo Backup, Ultimate Backup and many others.

Important Notes

A laptop is a rather closed device in terms of flexibility of settings. Increasing the frequency of the processor or memory will inevitably lead to overheating and premature failure of laptop components. Therefore, you should not have high expectations for BIOS construction projects. The maximum you can do is raise the processor frequency a little, if allowed by the manufacturer, and select a device to boot.

The last feature is useful when you need to boot from a flash drive. For example, this is necessary to fight viruses. In this case, you need to download the boot disk image from the antivirus developer’s website and boot from it. First, you must go into the laptop's BIOS and specify the USB drive as the main boot device.

We warn you - it is better to entrust operations to repair or improve a laptop to professionals . Most failures occur due to incorrect operation of programs in the operating system. BIOS is only an intermediary between the software and hardware of the laptop.

Restoring working firmware

If you did not make a copy of your OS and all the data that was stored on the device before flashing, and encountered problems when installing a new system, you will have to try hard to return the device to its previous performance indicators. The process of restoring the firmware can take more than one hour, and for each device model it may involve its own unique actions using additional software.

The best recovery option is to download and install via PC a licensed version of the firmware that you had originally installed.

Is tvsu.exe safe, or is it a virus or malware?

The first thing that will help you determine whether a file is a legitimate Windows process or a virus is the location of the executable file itself. For example, a process like tvsu.exe should run from C:\Program Files\lenovo\system update\tvsu.exe and not elsewhere.

To confirm, open Task Manager, select View -> Select Columns and select Image Path Name to add the location column to Task Manager. If you find a suspicious directory here, it may be worth investigating this process further.

Another tool that can sometimes help you detect bad processes is Microsoft Process Explorer. Launch the program (no installation required) and activate "Check Legends" in the "Options" section. Now go to View -> Select Columns and add “Verified Signer” as one of the columns.

If the Verified Signer process status is listed as Unable to Verify, you should take a look at the process. Not all good Windows processes have a verified signature label, but none of the bad ones do.

The most important facts about tvsu.exe:

  • Located in C:\Program Files\Lenovo\System Update\ subfolder;
  • Publisher: Lenovo
  • Full Path: C:\Program Files\lenovo\system update\tvsu.exe
  • Help file:
  • Publisher URL:
  • Known to be up to 13.4 MB in size on most windows;

If you had difficulties with this executable, you should determine if it is trustworthy before deleting tvsu.exe. To do this, find this process in the task manager.

Find its location (it should be in C:\Program Files\Lenovo\System Update\) and compare its size with the above facts.

If you suspect you may be infected with a virus, you should try to fix it immediately. To remove the tvsu.exe virus, you must download and install a complete security application such as Malwarebytes. Please note that not all tools can detect all types of malware, so you may need to try several options before you are successful.

In addition, the functionality of the virus itself may affect the deletion of tvsu.exe. In this case, you should enable Safe Mode with Networking , a safe environment that disables most processes and loads only the most essential services and drivers. When you can run a security program and complete system analysis .

After flashing the Play Market does not work

One of the most common problems after flashing Android devices is the lack of access to the Play Market. The problem is quite serious, since only the store can provide the user of an Android device with an abundance of additional useful and entertaining software.

There are an impressive variety of reasons for this problem, ranging from lost account settings to incorrect GAPPs. Each of the reasons has its own solution, and therefore, you will have to delve into the topic of how the Android OS works.

The update is not installed on the device

There are situations when, after downloading drivers for the device, programs for installing firmware on Lenovo via a PC and the archived operating system itself, you proceed to update, but cannot achieve results: at the very beginning of the process an error appears indicating that the gadget cannot be installed. stitched

Basically, the cause of this problem lies in the drivers or in the corruption of the firmware archive, but there are also minor troubles, the elimination of which takes only a few seconds, and after that you can safely and quickly continue to sew your smartphone or tablet.

How to fix tvsu.exe

Keeping your computer neat and tidy is one of the best ways to avoid problems with Lenovo System Update. This means running a scan for malware, cleaning your hard drive with cleanmgr and sfs/scannow to remove unnecessary programs, monitoring any startup programs (using msconfig), and turning on automatic Windows updates. Remember to always make regular backups or at least identify restore points.

If you have a more serious problem, try to remember the last thing you did or the last thing you installed before the problem. Use the resmon command to determine the processes causing your problem. Even in case of serious problems, instead of reinstalling Windows, you should try to repair your installation or, in the case of Windows 8, by running the command DISM.exe / Online / Clean-image / Restore Health . This allows you to restore the operating system without losing data.

To help you analyze the tvsu.exe process on your computer, you may find the following programs useful: Security Task Manager displays all running Windows tasks, including built-in hidden processes such as keyboard and browser monitoring or startup entries. The Unified Security Risk Rating indicates the likelihood that it is spyware, malware, or a potential Trojan horse. This antivirus detects and removes spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
