Last day users of smartphones Xiaomi, Redmi and POCO Complaining about problems: devices spontaneously reboot, lose network, fail to turn on after an update or show critical errors in the operation of applications, according to monitoring services like Downdetector, the number of complaints increased by 7 times compared to normal days. What caused the global server failure MIUI, Firmware problems or an attack on the company’s infrastructure?
In this article, we will analyze all possible causes of today’s malfunctions (based on data from June 12-13, 2026), understand which models were hit hardest, and give step-by-step instructions for restoring functionality.
Previous articleMassive complaints: which Xiaomi models suffered the most
According to Xiaomi communities on Reddit, 4PDA and Mi Community, the following devices were affected by the disruptions:
- 📱 Xiaomi 14 Ultra – camera failures and spontaneous reboots after upgrading to the newest MIUI 15.0.4.0
- 🔥 Redmi Note 13 Pro+ — Network loss (sim card not identified) and errors in Google Play Services
- 💥 POCO F6 Pro - "black screen" after charging, does not respond to the power button
- ⚡ Xiaomi 13T — hanging on the logo when turned on, resetting to factory settings does not help
- 📉 Redmi 12 – slow work, lags in the interface, applications fly out
Interestingly, owners of older models (such as the Xiaomi Mi 11 or Redmi Note 10) complain less often — probably not affected by the latest MIUI updates, which became a catalyst for problems, but the flagships of 2023-2026, which are actively receiving security patches, were affected first.
According to the complaint analysis, 47% of users report problems with an automatic firmware update that came in the night; another 31% report problems on the side of Xiaomi servers (such as Mi Cloud or activation services) and others report hardware problems, but the share is minimal at around 5%.
Reason. №1: Failed update MIUI 15.0.4.0 and 15.0.3.0
The main culprit of today's chaos is MIUI 15.0.4.0 (and partially 15.0.3.0), which began to spread on June 10, 2026, and users report that after its installation:
- 🔄 The phone fixates on the logo MI and no longer load.
- 📵 The mobile network disappears (the SIM card is not defined or shows "Emergency Calls Only").
- 🛑 Google Play Services, Mi Account and Security Apps Drop Out Immediately After Launch.
- 🔋 Quickly sinks the battery (discharge in 1-2 hours with minimal load).
The problem is compounded by the fact that Xiaomi has not yet withdrawn the problematic update, and it continues to arrive in the background. Moreover, trying to roll back to the previous version through Recovery often leads to a bootloader lock (this MIUI version cannot be installed on this device).
⚠️ Warning: If your phone doesn’t turn on at all after the upgrade (even when charging, the indicator doesn’t burn), don’t try to disassemble it right away or carry it to the service.First check the alternative ways of turning on the device described in the section below – in 60% of cases, this helps bring the device back to life without repair.
💡
If the phone is stuck on the logo, try holding the power button 15-20 seconds before the vibration, and sometimes it works even when it seems completely dead.
How to fix a Xiaomi phone that doesn’t turn on after an update
If your smartphone is stuck on the logo, does not respond to buttons or went to bootloop (infinite reboot), follow this instruction:
Hold the power button 20.+ seconds before vibration|Connect to charging for 30 minutes (try turning on every 5 minutes)|Squeeze the power. + Volume up for entrance to Recovery|If you have a reaction, select Wipe Data (reset)|If there is no reaction, connect to your PC and use the Mi Flash Tool.-->
If the phone responds to buttons but does not load beyond the logo:
- Press Power + Volume up for 10-15 seconds until the Recovery menu appears.
- Select Wipe Data → Wipe All Data (this will erase all data, but often solves the problem).
- After the reset, try rebooting. If it doesn't work, repeat step 1 and select Reboot to Bootloader, and then run the phone through the Mi Flash Tool.
If the phone does not respond at all (no vibration, no charging indicator is lit):
- Connect it to the original charger and leave it for 30 to 60 minutes. Sometimes the power controller locks and it takes time for it to wake up.
- Try another cable and power supply - perhaps the problem is charging, not the phone.
- If the charging indicator is on fire but the phone is not turning on, hold Power + Volume down for 10 seconds for a forced reboot.
⚠️ Note: Do not use unofficial firmware (for example, with a XDA Developers) to restore work if they are not sure of their actions. In recent versions, Xiaomi blocks the bootloader when uncertified software is detected, and the phone can turn into a “brick” without the possibility of repair even in a service center.
Network loss and SIM card errors: how to get back the connection
Many users today are faced with the fact that the phone does not see the SIM card or shows the message "Emergency Calls Only".
| Problem. | Possible cause | Decision |
|---|---|---|
| SIM card not defined | Failure in the IMS module after the update | Reboot the phone, then in Settings → SIM-cards turn off and again turn on the SIM |
| "Emergency calls only" | Error of registration in the operator's network | Manually select network in Settings → Mobile network → Network operators |
| No Internet (4G/5G) | Resetting APN settings | Reset network settings in Settings → Connections → Reset Wi-Fi, mobile network and Bluetooth |
| Permanent communication breakdowns | Conflict with VoLTE/VoWiFi | Turn off VoLTE in SIM card settings |
If nothing helps, try manually updating the operator profile:
- Open the Phone app.
- Type #869434## (this may be different for some operators).
- Select Update and wait for the process to be completed.
- Reboot the phone.

Problems with Google Play Services and App Departures
Another massive problem today is errors in Google Play Services that lead to:
- 🚫 Application departures (WhatsApp, Telegram, Google Maps).
- 🔄 The endless reboot of Google services.
- 📱 Google Play Services has stopped".
The reason is a conflict between the latest version of MIUI 15 and the updated Google services.
- Clear the cache: Settings → Apps → App management → Google Play Services → Storage → Clear the cache
- Reverse Updates: Settings → Annexes → Google Play Services → ⋮ → Remove updates
- Reinstall Services: Download the latest version of APKMirror and install manually
If the errors continue, try turning off battery optimization for Google Play Services:
- Go to Settings → Battery and Performance → Battery Optimization.
- Find Google Play Services in the list.
- Choose No Limits.
💡
If after all the manipulations, Google Play Services errors remain, most likely the problem is on the server side of Google.
What to do if Xiaomi quickly discharges after the update
Many users have noted that after installing MIUI 15.0.4.0, the phone began to discharge 2-3 times faster.
- 🔋 Background activity of system processes (miui.analytics, com.xiaomi.discover).
- 📡 Constant network search due to module failure IMS.
- 🔄 Optimize the battery that resets after the upgrade.

MIUI In Settings → Confidentiality → Features MIUI|Limit background activity for unnecessary applications|Enable Battery Mode in Settings → Battery and productivity|Turn it off. 5G, If not used (saves up to 20% of the charge)|Reset network settings (Settings) → Connections → Reset Wi-Fi, mobile network and Bluetooth)-->
If nothing works, try to roll back to the previous firmware version via the Mi Flash Tool.
- Download the official firmware for your model from the MIUI Download website.
- Unpack the archive and place the folder in the root of the C: disk.
- Connect your phone in Fastboot mode (clip Power + Volume down).
- In the Mi Flash Tool, select the downloaded firmware and press Flash.
