Tablets Texet based Android over time require firmware updates - this improves performance, fixes bugs and adds new features. However, the update process on devices of this brand has nuances: not all models support automatic update “over the air” (OTA), and some require manual firmware via a computer. In this article we will look at all current update methodsincluding preparing the device, finding the correct firmware and solving typical problems.

It is important to consider that Texet does not always provide official updates for older models (released before 2018–2019). If your tablet is older, you may have to use custom firmware - but this is risky and requires experience. We will focus on official methodsthat are suitable for most users.

Before you start, check your current Android version: go to Settings → About phone → Android version. Write down the tablet model (for example Texet TM-7045 or Texet TM-9750) - you will need it to search for firmware.

1. Preparing the tablet for the update

Improper preparation is the main cause of update failures. Follow this checklist to avoid problems:

Charge the battery to 80% or more

Create a backup copy of your data (photos, contacts, applications)

Connect to a stable Wi-Fi network (not mobile data!)

Make sure that there is enough free memory on the device (minimum 2-3 GB)

Disable antivirus and VPN (they can block firmware loading)-->

Pay special attention Backup. A firmware update may reset settings or delete data. Use Google Account to synchronize contacts and calendar, and for files - cloud services (Google Drive, Yandex Disk) or a physical drive. If important applications (for example, banking) are installed on the tablet, write down their names - after the update you will have to reinstall.

For models Texet with a small amount of memory (8–16 GB), it is recommended to transfer media files to card microSD or computer. The update requires temporary space to unpack the files, and if there is insufficient memory, the process may be interrupted.

⚠️ Attention: If your tablet Texet was purchased in regional networks (for example, Svyaznoy or M.Video), check whether the firmware is blocked by the telecom operator. Some devices are sold with preset restrictions.

2. Method 1: Update through settings (OTA)

The simplest method is automatic update “over the air”. It works if Texet released the official firmware for your model. Instructions:

  1. Connect the tablet to Wi-Fi (updating via mobile data may lead to additional costs).

  2. Go to Settings → System → Update system (on some models the path may differ: Settings → About phone → Software update).

  4. Confirm the download and wait for completion. Do not interrupt the process!

  5. After downloading, click Install and follow the instructions on the screen. The tablet will reboot.

If the system writes "No update", this may mean:

  • 🔹 Your model Texet is no longer supported by the manufacturer.
  • 🔹 The update has not yet been released for your region (sometimes firmware is released first for Europe, then for the CIS).
  • 🔹 The device has custom firmware installed that blocks OTA.
💡

OTA update is the safest method, but it only works for supported models. If the system does not find updates, proceed to manual methods.
