How to find out the version of the PCT (RST) on the Xiaomi TV: all working methods

If you own a Xiaomi TV (Mi TV, Redmi Smart TV, Xiaomi TV A or Xiaomi TV Q) and are faced with the need to know the version of the PCT (or RST - Reset Status Table), this article will help to understand the nuances. The term "PCT" often occurs in the context of firmware, resetting or fault diagnosis, but the official documentation of Xiaomi rarely discloses it in detail.

It is important to understand that a PCT is not the same as a firmware version (MIUI TV or Android TV), a separate parameter that can affect the operation of the device after updates, resets or repairs. For example, if the TV after firmware behaves unstable (spontaneously restarts, does not save settings or gives an error E10001), checking the PCT will help diagnose the problem.

In this article, we’ll look at all the current ways to get information about PCT, from standard menus to hidden commands and service modes, and you’ll learn why you need this option at all and how to reset it if you need it.

What is a PCT in Xiaomi TVs and why check it

The abbreviation PCT (or RST) in the context of Xiaomi TVs can mean:

  • πŸ”„ Reset Status Table – Reset Status Table, which stores data on the latest factory resets, updates and critical errors.
  • πŸ› οΈ Recovery Status Tag – a recovery status label used by service centers for diagnosis.
  • πŸ“Š Region Settings Table – table of regional settings (in some models, for example, Mi). TV 4S or Redmi X50).

The main reasons why a user may need to know the PCT are:

  • ⚑ The TV does not turn on after updating the firmware (black screen, flashing indicator).
  • πŸ”§ Incorrect work after resetting to factory settings (for example, language settings are lost or sound disappears).
  • πŸ”„ Preparation for firmware through ADB Fastboot (some custom firmware requires PCT checks).
  • πŸ“¦ Buying a used TV – checking whether it was not in repair or blocked the region.

In Xiaomi’s 2020-2026 PCT models, the PCT is often tied to an eMMC memory chip and can affect system speed after multiple resets, for example, if the PCT value exceeds 0x0005, this may indicate memory wear and need to replace the module.

⚠️ Note: In some firmware (for example, MIUI TV 3.0 and below) trying to reset a PCT through an engineering menu can result in locking the bootloader.Before any manipulation, make sure you have a backup of the data.

Method 1: Check PCT through the standard settings menu

The easiest method is to use the TV’s built-in settings, which are suitable for most Xiaomi models based on Android TV or MIUI TV (including Mi TV 4A, Mi TV 5, Redmi Smart TV X, etc.).

Instructions:

  1. Turn on the TV and go to the main menu by pressing the Settings button (βš™οΈ) remote.
  2. Select Device β†’ About TV (or System β†’ About in English firmware).
  3. Scroll down to System Info (System Info).
  4. Find the RST Version, Reset Status, or eMMC Health strings – the current PCT value can be displayed here.

If you don't have PCT information on this menu, try clicking on the MIUI TV (or Android TV OS) version 5-7 times in a row, and in some firmware, this opens a hidden menu with additional options, including PCT.

Check the firmware version (update if necessary)

Restart the TV.

Try another way (ADB or service menu)

Contact Xiaomi Support (Please specify the model and version of the software)-->

On some models (e.g. Xiaomi TV Q1E), the PCT value may be hidden behind Storage & reset β†’ Factory data reset. When you click on it (without reset confirmation!), sometimes a pop-up with technical information, including PCT, appears.

Method 2: Use of the ADB-Teams (for advanced users)

If the standard menu does not show PCT, you can use ADB (Android Debug Bridge), which requires connecting the TV to a computer and basic knowledge of working with the command line.

Step-by-step:

  1. Turn on USB debugging mode on your TV: Go to Settings β†’ About TV. Find the Build Number and click on it 7 times until the notification β€œYou’ve become a developer” appears. Go back to the main settings menu, select Developer For, and activate Debugging on USB.

Connect the TV to your computer through USB-port (use a cable with data transmission support).

ADB Tools

cmd

Terminal

adb devices

Make sure the device is identified (should appear its serial number).

PCT

adb shell getprop | grep -i "rst\|reset\|emmc"

Or alternative command (for some models):

adb shell cat /proc/emmc_info

If the commands return an empty result, try an alternative request:

adb shell dumpsys power

In the conclusion, look for lines with a mention reset_count or boot_reason β€” These are indirect indicators of the status of PCT.

What if ADB can’t see TV?
1. Check the cable – it should support data transfer (not all) USB-Charging cables are suitable. 2. Install drivers for your model (e.g. "Xiaomi Mi") TV ADB Drivers). 3. Try another one. USB-port on the computer (better to use) USB 2.0. 4. Restart the TV and PC. 5. If you are using Windows, disable driver signatures (in diagnostic mode).

⚠️ Note: On Xiaomi TVs with an Amlogic chip (e.g. Mi) TV 4A or Redmi Smart TV X55) Adb shell commands may be limited, in which case try root access via Magisk or use the service menu method (described below).

Method 3: Service menu (Engineer Mode)

The hidden service menu allows you to access the technical settings of the TV, including the PCT. However, the entry to this mode varies depending on the model and firmware version.

Instructions for most Xiaomi models:

  1. Turn on the TV and go to the main screen.
  2. On the remote, press the buttons sequentially: Menu β†’ Up. β†’ Up. β†’ Down. β†’ Down. β†’ Left. β†’ Right. β†’ Left. β†’ Right (analogue of the Konami Code combination).
  3. If the combination didn’t work, try the alternative: Settings β†’ All settings β†’ Support β†’ Press the β€œLoudness +” and β€œLoudness –” buttons on the remote for 5 seconds at the same time.
  4. In the service menu that opens, find the eMMC, Storage or Factory tabs – PCT (Reset Count or RST Value) can be displayed here.

On some models (for example, Xiaomi Mi TV 5 Pro) the service menu is opened via ADB command:

adb shell am start -n com.android.tv.settings/.device.devicesettings.DeviceSettingsActivity
Model TV setCombination for Entry into Engineer ModeWhere to look for PCT

Another model-->

If you see a PCT value in 0x0003 or RST:5 in the service menu, it means the number of resets or critical events. A value above 0x0007 may indicate a memory malfunction or need to flash it.

Method 4: Checking through documentation and stickers on the TV

If the TV is not turned on or the menu is not available, you can try to find information about the PCT in the physical documentation or on the device itself.

Where to look:

  • πŸ“„ Box and documentation: On some models (e.g. Xiaomi Mi) TV 4S 55") the user manual or warranty card may indicate the initial PCT (usually 0x0000 or RST: 0).
  • 🏷️ Sticker on the back: Next to the serial number (S/N) Information is sometimes published, including FW Ver (firmware version) and RST. Example: S/N: XM234567890 FW Ver: V123.45.678 RST: 0x0002
  • πŸ“‹ Warranty card: In service centers Xiaomi during repair can make changes to the PCT and fix it in the documents.

If the sticker or documents have a string of RST or Reset, but the value is missing, this may mean that the TV has not been reset or repaired. However, the lack of information does not guarantee the health of the device - some models (for example, Redmi Smart TV X55) do not display PCT on the stickers.

πŸ’‘

If you buy a used Xiaomi TV, ask the seller to provide a photo of the stickers from the back. Compare the serial number to the data in the Settings menu β†’ About the TV - they must match. The discrepancies may indicate a replacement motherboard or a fake.

Method 5: Appealing for Xiaomi

If the independent methods did not help, you can request information about the PCT from official support Xiaomi.

  • πŸ”§ TV on warranty and you suspect factory marriage.
  • πŸ“¦ You bought a used device and want to check its history.
  • πŸ”„ After the firmware update, errors related to PCT arose.

How to request data:

  1. Prepare the following data: Serial number of the TV (S/N β€” on the sticker or in the Settings menu β†’ Model (e.g. Mi) TV 5 Pro 65"). Firmware version (MIUI TV Android TV). Photo or video problems (if any).
  2. Contact support via: Official website: mi.com/support. Chat in the Mi Home app (if the TV is linked to the account). Social networks (Twitter, Facebook - answers come faster than through email).

Please provide information on the current status of the RST (Reset Status Table) for malfunction diagnosis.

Support usually responds within 1-3 days. If the TV is warranty, they may offer free repairs or replacements. For devices older than 2 years (e.g. Mi TV 4A 2018), payment for diagnostics may be required.

⚠️ Note: In some regions (e.g. Russia or the EU), Xiaomi support may refuse to provide information about the PCT, citing the privacy policy, in which case only a service center or self-diagnosis through the use of the device is left. ADB.

What to do if PCT is incorrect

If you find that a PCT has a high value (e.g., 0x000A or higher), this may indicate:

  • πŸ”„ Multiple resets to factory settings (more than 5 times).
  • πŸ› οΈ Failed firmware attempts via Fastboot or Recovery.
  • πŸ’Ύ EMMC memory wear (relevant for TVs over 3-4 years old).
  • πŸ”Œ Power problems (frequent shutdowns without properly shutting down).

Possible solutions:

  1. Reset PCT to factory value: For Android models TV You can use the command: Adb shell reset_rst (It doesn't work on all firmware. It works on TVs. MIUI TV Sometimes it helps to completely reset through the service menu (Factory Reset All item).
  2. Download the official firmware for your model from miuirom.org. Use the Mi TV Assistant or USB Burning Tool for USB firmware.

Replace the eMMC memory:

If the TV stopped turning on after resetting the PCT, don’t panic – it could be a temporary bootloader failure. Try to disconnect it from the network for 10 minutes, then hold the power button on the remote for 20 seconds.

FAQ: Frequent questions about PCT on Xiaomi TVs

πŸ” What is a PCT in Xiaomi TVs in simple words?
A PCT (or RST) is an internal counter that records the number of critical events, such as resets, failed updates, or memory errors, and can tell you how worn a device is, for example, if a PCT is 0, the TV has not been reset; if 5 or higher, there may have been a firmware or memory problem.
⚠️ Can I reset the PCT on my own?
Yeah, but not on all models. TV (for example, Xiaomi TV Q2) You can try the Adb shell command. reset_rst. Nana MIUI TV Sometimes a full reset from a service menu helps, but resetting a PCT doesn't always solve the problem -- if it's memory wear, it'll need repairs.
πŸ“‰ What is the value of PCT is considered critical?
PCT values up to 0x0003 (or 3 in decimal format) are usually not a concern. If the value exceeds 0x0007 (7), this may indicate: Frequent resets (more than 5 times). Failed firmware. Memory wear eMMC (relevant for TVs older than 4 years).
πŸ”§ How to check PCT if the TV is not turned on?
If the TV doesn't respond to the remote and doesn't show the image, but the power indicator is on, try: Connect the TV to the computer via USB and check the PCT through ADB (if the bootloader is not locked). Use the USB Burning Tool to read logs (requires firmware and a USB A-A cable). Contact the service center - they have special tools to diagnose faulty devices. If the indicator does not burn at all, the problem may be in the power supply unit, not in the PCT.
πŸ›’ Does PCT affect the cost of a used Xiaomi TV?
A high PCT value (e.g., 0x000A) may indicate: Frequent resets (possibly, the TV is sold due to malfunction); memory wear (risk of future failures); repairs in unofficial service. When buying a used device, ask the seller: Photo of the service menu with PCT. Check or warranty card (if the TV was repaired); Video of the TV (on, switching channels, updating the firmware); The cost of a high PCT TV can be lower by 20-30% compared to similar models.
