When you find a message that says “file type is not supported” or “file is corrupt” on a Xiaomi smartphone, it causes panic. This is especially unpleasant if the memory card or internal memory stores unique frames that cannot be reshooted. Android on the shell of MIUI or HyperOS can give this error for various reasons, from a banal failure of the file system to physical damage to the storage sectors.
It is important to understand that reading error does not always mean permanent loss of data. Often the problem lies in a software conflict or damage to the file header, which can be fixed by specialized utilities. Before you despair and delete "broken" images, it is worthwhile to thoroughly diagnose the device and try to restore the data structure with available methods.
In this guide, we will look at proven ways to resuscitate photos on Redmi and Poco devices. We will look at both built-in system tools and third-party PC tools that will help you regain access to your images. The main thing is to act consistently and not write new information to a damaged medium until all procedures are completed.
Reasons for Reading Mistakes on Xiaomi
When you report that the file format is not supported, it often results from a system failure, and if you remove the microSD card during a photo shoot, or force your smartphone to turn off while you save the image, the file system may not have time to close the record index, leaving the file title empty or containing erroneous data, which leads to the gallery's refusal to open the image.
Another common cause is physical wear and tear or the appearance of “broken” sectors: the internal memory of Xiaomi phones, especially high-storage models, can degrade over time. When the system tries to read data from a damaged physical sector, it can not decode the flow of bytes and emits a standard compatibility error.
Software conflicts should also be considered. Once you update your MIUI firmware or install a third-party launcher, the standard Gallery app may lose access rights or stop interpreting certain codecs correctly. Sometimes the problem lies not in the file itself, but in the cache of the media scanner that incorrectly indexed the contents of the folder.
⚠️ Note: If you notice that the file is corrupted on a massive scale across file types (video, documents, photos), this may indicate a critical failure of the memory controller.

Diagnosis and primary actions
The first step is to determine the scope of the problem. Try opening the problem photo on another device by connecting your smartphone via USB to your computer or sending a file to another phone via Bluetooth. If the image opens on a PC, then the problem is solely in your Xiaomi software, most likely in the codecs or cache of the gallery.
If the file is not read anywhere, you need to check the state of the drive. For microSD cards, you can do this by connecting them through a card reader to your computer and running the standard Windows error check utility. Internal memory will require the use of diagnostic applications from Google Play, such as SD Maid or built-in developer tools.
Often, a simple reboot of a device in safe mode helps, eliminating the influence of third-party applications that could have intercepted control of the file system, and if photos are opened in safe mode, then the conflicting application must be found and removed.
Don’t ignore the system’s messages of space shortage. When the free space of internal memory falls below 500 MB, the Android operating system starts to run unstable, which can lead to data corruption while saving new files. Freeing up space is a basic necessity for a stable file system.
Use of built-in recovery tools
The MIUI and HyperOS shells have their own set of maintenance tools that users often ignore. Security has a clean-up and optimization feature that includes checking the file system for errors, and running this procedure can automatically correct small logical inconsistencies in the folder structure.
It's also worth trying to clean up the Gallery and Media Storage system app, which won't delete your photos, but will reset the thumbnail and index database. To do this, go to Settings → Apps → All apps, find Gallery and click Clear Data. After you reboot, the system will rescan all media files.
In some cases, switching the mode helps. USB. If you connect your phone to a PC, try changing the mode from File Transfer (MTP)» to “Photo transmission (PTP)». Sometimes the driver MTP Incorrectly handles damaged headers, while PTP-The protocol can allow you to copy the raw data of the file for subsequent recovery on the computer.
💡
Before resetting your gallery settings, make sure that sync with Mi Cloud or Google Photos is enabled to have a backup in the cloud in case of unforeseen errors.
If built-in methods don't work, move on to more serious tools, however, even simple actions like cleaning the cache often solve the problem if it's caused by a software failure after a system update.
Recovery through computer and third-party software
The most effective way to reanimate damaged photos is to use specialized software on your computer. Software like Recuva, PhotoRec or Stellar Photo Recovery can analyze raw data from the media and restore the structure of the file, ignoring the damaged header. Connect your smartphone in debugging mode via USB or remove the memory card.
The recovery process usually takes time and depends on the amount of memory, and programs scan sector by sector, trying to find signatures of known image formats (JPEG, PNG, HEIC). If the file body is intact, the utility will reassemble it and assign a new name, saving it to the recovery folder.
For advanced users, the FFmpeg command tool is available. With it, you can try to recode a damaged video or image without reading errors. The command can look like an attempt to copy a stream with the missing frames, which often makes the file playable again.
ffmpeg -i damaged_photo.jpg -c copy restored_photo.jpgIt’s worth noting that paid versions of recovery software often have a preview: they show you if you can save a file before you ask for payment, a convenient way to avoid spending money on data that is not retrievable.
☑️ Checklist before data recovery
Prevention and work with cloud services
The best protection against data loss is duplicating it. The Mi Cloud service built into Xiaomi smartphones allows you to automatically upload photos to the cloud. Even if a file on your device gets corrupted, its latest working version can be saved in the cloud.
Check the health of your memory card regularly. If you use a microSD to store a photo, copy it every six months to your computer and format it. Format redistributes sectors and labels damaged areas as unused, preventing new data from being written to dangerous areas.
Avoid using cheap memory cards of unknown brands. They often have real capacity less than claimed and use poor-quality memory chips that quickly fail when recording actively, which is typical for serial shooting or recording video in 4K.
| Method | Efficiency | Difficulty | Risk of data loss |
|---|---|---|---|
| Clearing the Gallery's cache | Low (soft only) | Low. | Absent. |
| Programs on PC (Recuva) | Tall. | Medium | Minimum |
| Formatting a map | Medium (heals card) | Tall. | Complete removal |
| Service centre | Maximum | Low. | Depends on the case. |
When a service center is needed
There are situations where independent actions are powerless. If a Xiaomi smartphone freezes after trying to read a file, goes into a cyclic restart (bootloop) or gets very hot in the processor area, this indicates a hardware malfunction of the memory controller, in which case any attempts to write or read can finish the device completely.
And we need help if data is critical, and in the lab, engineers can brazel out a memory chip and read it directly on the programmer, bypassing the logic errors of the controller, which is expensive, but often the only procedure for complex cases.
⚠️ Warning: Do not try to freeze or tap on your phone if it has stopped reading files.Mechanical exposure or temperature changes can cause contact detachment BGA-Rations that will turn a software problem into a complex hardware repair.
Contacting Xiaomi’s authorized service center is preferable because it uses original parts and has access to the manufacturer’s closed diagnostic utilities, but if the warranty is not important and data is urgently needed, specialized data recovery laboratories will do better than conventional repair shops.

Concluding recommendations
The problem with reading files on Xiaomi is solved in most cases, if you approach the question correctly. The main rule is not to panic or do unnecessary actions with the file. Every attempt to open a damaged photo or overwrite a sector reduces the chances of a successful recovery.
Use modern cloud storage techniques as your primary archive and treat your phone as a working tool. Regular backups are the only way to sleep well, knowing that your memories are safe, regardless of the state of the gadget.
💡
Detecting an error and stopping the drive can increase the chances of data recovery by up to 90%.
Remember that prevention is always cheaper and easier than treatment: Keep an eye out for system updates, use quality memory cards, and keep your smartphone’s internal storage from overflowing.
💡
Install an SSD/memory health monitoring app if your model allows it to do so through ADB to know in advance about the wear and tear of the drive.
