How to Update Teclast Tablet Firmware: OTA & Full Flash Guide
This guide explains how to update or reflash the firmware on a Teclast tablet, using Teclast’s own official instructions. There are two methods: the offline OTA update, which installs a signed package from within the system and keeps your data, and the full PhoenixSuit flash, which rewrites the whole firmware from a computer and erases the tablet. Flashing carries risk and can wipe all data, so back up anything important first, and make sure the firmware version you download matches your exact device.
Before you start
- Back up any important data — a full flash erases everything on the tablet.
- Remove the microSD card before upgrading.
- Make sure the battery is at least 30% charged.
- Have a computer with internet access and a USB data cable (the tablet’s charging cable works).
- Find the 4-character Product ID (4 letters/numbers) printed on the back of the device — you need it to download the right firmware.
💡 The version you download must match your device exactly. Installing the wrong package will fail or can brick the tablet.
Find your Product ID and download the firmware
- Locate the 4-character ID number on the back cover of your tablet.
- On a computer, open the official Teclast site (en.teclast.com) and go to Support → Firmware Download (Software Download).
- Use “Search by Product ID Number”, enter your 4-character ID, and search.
- Download the firmware version that matches your device, then extract the compressed package.
💡 You can also download official Teclast stock firmware free on ROM Palace — direct links, no waiting queue.
Method 1 — Offline OTA update (keeps your data)
Use this if the tablet still boots normally. It installs the update from the tablet’s own System Update menu and preserves your data.
- On the tablet, open Settings → About tablet and scroll down to note the current version under Build number (it must match the package you downloaded).
- Connect the tablet to the computer with the USB cable (USB end to the computer, Type-C end to the tablet).
- Swipe down from the top of the tablet and tap the USB notification, then under “Use USB for” select File Transfer.
- On the computer open This PC, open the tablet’s drive, and copy the downloaded upgrade package to the tablet’s root directory.
- On the tablet, open Settings → About tablet → System Update.
- Tap More (top-right) → Local upgrade, then select the package you copied to the root directory.
- Tap INSTALL NOW and confirm with OK. The update takes about 20 minutes.
- When prompted, choose Power off and restart. After rebooting, check Settings → About tablet to confirm the new version installed.
Method 2 — Full flash with PhoenixSuit (Allwinner tablets, wipes data)
Use this for a clean reflash or to recover a tablet that won’t boot. It uses the PhoenixSuit tool bundled in the firmware package and erases all data. This applies to Allwinner-based Teclast tablets.
- On the computer, turn off any antivirus, then open the Upgrade Tools folder and run PhoenixSuit_EN.msi. Click Next through the installer (including the driver install) and Close when done.
- Launch PhoenixSuit from the desktop shortcut and open the Firmware page.
- Click Image, then select Firmware.img inside the Firmware folder and open it.
- Choose the “Wipe part” mode.
- Power off the tablet. Hold Volume Up, connect the tablet to the computer, then press the Power button 5–10 times in a row until the upgrade starts. Release Volume Up and wait.
- The flash takes about 3–5 minutes. When it finishes, the tablet powers on automatically — the first boot may take longer than usual, so be patient.
💡 Do not disconnect the tablet or close PhoenixSuit while flashing — an interrupted flash can brick the device.

Frequently asked questions
How do I update my Teclast tablet without losing data?
Use the offline OTA method: download the matching firmware from Teclast, copy it to the tablet’s root folder, then install it from Settings → About tablet → System Update → Local upgrade. This keeps your data. A full PhoenixSuit flash, by contrast, erases everything.
Where do I find my Teclast tablet’s Product ID?
It’s a 4-character code (letters and numbers) printed on the back cover of the tablet. Enter it in “Search by Product ID Number” on en.teclast.com under Support → Firmware Download to get the exact firmware for your device.
My Teclast tablet won’t boot — can I still flash it?
Yes. Use the PhoenixSuit method: install PhoenixSuit on a computer, load the Firmware.img, choose Wipe part, then hold Volume Up and tap the Power button 5–10 times to start the flash. This rewrites the whole firmware but erases all data.
