If your Xiaomi smartphone started to slow down, spontaneously reboot or behaves unstable, support engineers often ask for the help of the company. KLO BugReport is a special file with detailed logs of the system, and this report contains critical information about the state of the device at the time of a failure, from the processor load to the errors in the operation of applications, without it, diagnosing the problem becomes divination in the coffee grounds.
Many users confuse BugReport with a normal error screenshot or memory dump, but these are fundamentally different things. For example, if your Redmi Note 12 suddenly turns off when the camera starts, the standard log from Settings is the same. โ The phone. โ Version. MIUI It's not going to show you the full picture. KLO BugReport will record everything from processor temperature to driver conflicts in the last 5-10 minutes of work, which is why it is required not only in the official Xiaomi service, but also on enthusiast forums where complex bugs are analyzed.
In this article, we will discuss:

What is it? KLO BugReport and why you need it
KLO BugReport is an advanced state report that is generated by the Android kernel at the user's request. Unlike standard logs (available through adb logcat), it records all the events in the system over the past few minutes, including the logs that are available on the Android kernel:
- ๐ Downloading CPU/GPU kernel-process
- ๐ฅ Temperature of chipset, battery and other components
- ๐จ Kernel Panic Errors and Driver Failures
- ๐ฑ Status of memory (use) RAM, swap, zombie processes)
- ๐ Logs of communication modules (Wi-Fi, Bluetooth, mobile network)
- ๐ฎ Activity of applications and services in the background
Main advantage KLO BugReport before other diagnostic methods - its completeness. POCO X6 Pro overheats when playing Genshin Impact, the usual logcat will show only application errors, and BugReport will also show the error:
- ๐ฅ Temperature sensors in real time
- โก Battery voltage and current
- ๐๏ธ Processor frequency (throttling due to overheating)
Without this report, Xiaomi engineers can only guess what caused the problem, and with it, they can determine whether the firmware bug, the driver-Conflict, or the hardware malfunction is to blame.
How to create KLO BugReport on the smartphone Xiaomi
How you generate a report depends on the firmware version. MIUI 14+/HyperOS The algorithm is simplified, but for older models (for example, Redmi Note). 9 on MIUI 12) So, you need to take additional steps. Below is a general-purpose manual that's going to work for you. 90% case.
Method 1: Developer menu (recommended)
This is the most reliable method that works on all Xiaomi devices with unlocked bootloader or enabled debugging. USB.
โ๏ธ Preparation for the creation of BugReport
- Connect your smartphone to your computer USB and allow debugging (a request will appear on the phone screen).
- Open the command line (Win) + R โ Type in cmd and execute the command: adb shell am broadcast -a com.xiaomi.mitv.debug -.flag bugreport
- Wait for the notification on the phone when the data collection is completed (usually takes 1-3 minutes).
- The report file will appear in the folder /sdcard/bugreports/ name-name bugreport-MODEL-DATE.zip.
adb shell "echo 'bugreport' > /data/local/tmp/bugreport_trigger"Then restart the phone and the report will be automatically generated.-->
Method 2: Engineering menu (for older models)
On devices before MIUI 12 (e.g. Mi 9 or Redmi Note 8 Pro) you can use a hidden engineering menu:
- Open the Phone app and enter the combination: ##4636##.
- Go to the Usage Statistics section โ Bug report.
- Click Generate report and wait until it is completed (it can take up to 5 minutes).
- The file will be saved in the Downloads folder or MIUI/bugreport.
What should I do if I donโt create a report?
Method 3: Automatic generation when failure occurs
Some critical errors (such as kernel panic or bootloop) automatically create a memory dump. /data/dontpanic/, But to extract them, you will need root rights or access via fastboot.
โ ๏ธ Warning: If the phone doesn't turn on or gets stuck on the logo MI, Do not try to extract BugReport yourself, in this case, it is better to contact the service center immediately - incorrect actions can lead to complete loss of data.
What data are contained in KLO BugReport and how to read it
File. KLO BugReport is a.zip archive that contains text logs and binary dumps:
| File/Folder | Description | Example of data |
|---|---|---|
| bugreport-MODEL-DATE.txt | Main log with information about the system, processes and errors | Build: HyperOS 1.0.3.0.UMBMIXMKernel: 4.19.157-perf+ (android13-5.10.61) |
| dumpsys/ | Android service status dumps (Wi-Fi, Bluetooth, battery, etc.) | Battery: level=87, temperature=38.2, voltage=4.3V |
| proc/ | Images of processes, memory and CPU at the time of the report creation | PID 1234: com.miui.home, CPU=15%, Mem=450MB |
| kernel_log | Logs of the kernel (critical driver errors, overheating) | [ 123.456789] thermal_engine: Temp=92ยฐC, throttling CPU |
| events.log | System Events (launch/stop applications, network changes) | 05-20 14:30:45.123 AppCrash: com.tencent.mm (WeChat) |
To analyze logs, you do not need to be a programmer - just know what to pay attention to:
- ๐ฅ Overheating: Look for strings with thermal, overheat or throttling in files kernel_log and dumpsys/battery.
- โก Quick discharge: B dumpsys/battery Check the Health section and consumption schedule by process.
- ๐จ Application departures: In events.log, look for records from ANR (Application Not Responding or crash.
- ๐ถ Network problems: B dumpsys/wifi or dumpsys/telephony See connection statuses and authentication errors.
For convenience, you can use specialized tools:
- ๐ฅ๏ธ Android Studio + Logcat: Opens logs in a convenient form with filtering.
- ๐ Notepad++ Compare plugin: Helps to compare logs before and after a crash.
- ๐ Online analyzers: For example, Logcat Viewer (load logs carefully - they may contain personal data!).
๐ก
The most valuable information for diagnosis is usually in files. kernel_log (hardware failures) and dumpsys/battery (If there are a lot of thermal throttling records in the report, it's probably the problem with the chipset or the battery overheating.
Where and how to send KLO BugReport
Generating a report is half the battle, and to help solve a problem, you have to send it right in support. Here's a step-by-step guide.
1. Preparation of the file
- ๐ Rename the archive by template: BugReport_Model Problem Date.zip (example: BugReport_POCO_F5_Overheating_20260520.zip).
- ๐๏ธ Pack it in an additional archive (for example,.7z) โ This will reduce the size and speed up the loading.
- ๐ Remove personal information (phone numbers) from logs, IMEI) โ Open bugreport-*.txt in the text editor and replace sensitive data with XXXX.
2. Where to send.
| Support channel | Reference | Features |
|---|---|---|
| Official Xiaomi Forum | new.c.mi.com | It's good for global firmware. It can be answered in 3 to 7 days. |
| Mi Community Support Service | mi.com/support | They react more quickly to iron problems (such as overheating). |
| Telegram chat Xiaomi Bug Tracker | @XiaomiBugTracker | Itโs an unofficial channel, but itโs often where Xiaomi engineers sit. |
| Local service centre | โ | If the problem is hardware (such as a bloated battery), it is better to carry the phone in person. |
3. How to make an appeal
When sending a report, be sure to indicate:
- ๐ฑ Device model (exact, for example, Redmi Note 12 Pro)+ 5G (rubens)).
- ๐ฆ The firmware version (find in Settings) โ The phone. โ Version. MIUI/HyperOS).
- ๐ง Description of the problem (when it arises, how it is reproduced).
- ๐ Date and time of failure (if linked to a specific event).
Example of correct message:
Theme: POCO F5 Pro - spontaneous reboot when charging Message: Hello! POCO F5 Pro (codename marble) on HyperOS firmware 1.0.4.0.UMBMIXM spontaneously reboots when connected to charging (using the original adapter) 120W). The problem started after the update. MIUI 14. I'll attach a log to the report that was created immediately after the failure, and I'll ask you to check if it's connected to the power controller driver: BugReport_POCO_F5_Pro_Reboot_20260520.zip
๐ก
If the problem is related to a particular application (e.g. Google Camera crashes), specify its version and steps to reproduce the error, which will speed up the diagnosis by 2-3 times.
Common BugReport Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes that make the report useless.
- Collecting a report at the wrong time: If you create BugReport 10 minutes after a crash, it wonโt capture critical data; you need to generate the report immediately after the problem occurs (ideally within 1-2 minutes).
- Lack of space on the device. If the phone has less than 100 MB of free space, the system may not save a full report. Before generating, clear the cache or transfer files to the PC.
- Using a non-original cable. Cheap. USB-The cables often don't transmit data correctly, which is why the adb command doesn't work. Use Xiaomi's proprietary cable.
- Sending incomplete files. Sometimes users only upload bugreport.txt, ignoring dumpsys and proc folders. Without them, diagnosis is impossible.
- They forget to give context. Reports without a problem are useless. Always add what happened, when and under what conditions.
โ ๏ธ Note: If you send BugReport for a mobile network problem (for example, it disappears). 5G), Before you generate the report, play back the error: turn on/off flight mode or restart the phone.
Alternative diagnostic methods if BugReport does not help
In some cases KLO BugReport may not give you the full picture, for example, if the problem appears once a week or is related to a hardware malfunction (for example, a memory chip dump:
1. Logs through ADB real-time
If the failure is stable (for example, the game crashes after 5 minutes), you can write logs directly at the time of the problem:
adb logcat -d > logcat_before.txt
Repeat the mistake
adb logcat -d > logcat_after.txtCompare the two files with Notepad++ WinMerge to find differences.
2. memory dump in critical failure
If the phone goes to bootloop or turns off with a black screen, try extracting it. last_kmsg (kernel log before collapse):
adb pull /proc/last_kmsgThis file often contains the cause of a hardware failure (e.g., a power controller error).
3. Iron tests
To check the hardware components, use:
- ๐ AccuBattery: Monitoring battery status and current consumption.
