The pattern file is still on your phone, but the LINE message explaining which measurements to use has disappeared. Was that number in centimeters or inches, and did the maker's last message change the sleeve length? When you need to recover deleted LINE messages on Xiaomi 17 Ultra without a backup, a surviving design photo may not answer the questions that matter.
Dr.Fone - Data Recovery (Android) offers a device-scan route for supported phones: look for available LINE conversations, preview their contents, and check shared photos, videos and files in a separate attachment view. You can save the useful records to a PC instead of rebuilding a custom order from memory. First check whether the conversation or an independently saved pattern is still accessible, then follow the Windows recovery workflow.

Before you start
Match the Xiaomi 17 Ultra configuration
The supplied support record lists Xiaomi 17 Ultra with Android 16 and kernel 6.12.23. Check the phone's model and software information against those conditions. This is the Ultra entry, not a blanket statement about other Xiaomi phones or arbitrary firmware combinations.
Preserve the phone and prepare Windows
Advanced Recovery is Windows-only. Prepare a USB data cable and a private folder on your PC. Keep LINE installed and preserve its storage: do not clear app data, reinstall LINE, log out, reset the phone or downgrade it to match a support entry. Follow the product's displayed connection and access prompts. The supplied information does not establish a lossless Root procedure or a specific Root mechanism, so do not improvise unlocking or flashing steps.
Identify the missing instruction, not just the missing file
Note the maker or group, approximate exchange date and the details you need: measurement units, pattern-piece labels, an annotated photo or a later correction. Recovery depends on local data the scan can still discover. Selected output is saved to a PC, not imported into the LINE conversation.
Check a hidden LINE chat and any retained pattern files
Use these checks when the conversation may only be hidden, or when the original pattern survives but its chat instructions are missing.
Step 1 Rule out a hidden conversation
In LINE, go to Home > Settings > Chats > Hidden chats > Edit > Unhide chat for the relevant conversation. If the old messages return, read the measurement explanation and any correction that follows it. Unhiding reveals retained history; it does not recover deleted messages.
Step 2 Inspect an accessible chat's shared files
If the chat still contains relevant content, open its top menu > Photos & videos > Files. For an available pattern file, open the options beside it and choose Jump to message to check the surrounding explanation. The Photos & videos tab can help you distinguish an annotated pattern image from a general inspiration photo. This only works for content still accessible in the chat.
Step 3 Compare independently saved source material
Look in the folder where you previously saved the pattern, or in the original email if the maker also sent it there. Ask the maker for their retained instructions if needed. Keep that newly supplied copy separate from recovered records: a replacement pattern or a fresh explanation is useful, but it does not recreate the wording of the deleted exchange.
- Deleting a whole LINE chat also deletes it on other devices using the same account. A signed-in PC is not an independent full backup of that deleted thread.
- If the instructions were truly deleted and no usable copy remains, continue to the phone scan rather than repeatedly reopening the same file.
Which LINE records answer your pattern questions?
| Missing detail | Useful record to inspect | How to interpret it |
|---|---|---|
| A number without its units or measurement reference | The message defining the measurement and nearby replies | Keep the number, units and explanation together; a detached number is ambiguous. |
| Which pattern piece or side an instruction refers to | Available labeled image or pattern file plus its message context | Check the actual labels. A mirrored reference photo is not evidence that the pattern was changed. |
| Whether a later adjustment replaced an earlier instruction | The later correction and any associated updated attachment | A filename alone cannot establish that the maker accepted or applied the change. |
| A demonstration or reference clip | A playable video in LINE Attachments | Use the available clip alongside text; its presence does not establish that every instruction was recovered. |
Common problems and fixes
The pattern opens, but the measurement explanation is absent
Review the LINE conversation results as well as LINE Attachments. A pattern file and the messages explaining it are different records. If only the file is available, save it and ask the maker to confirm the missing units or references rather than treating an inferred measurement as recovered text.
Several similar pattern images appear in the results
Preview each available image for its piece labels, annotations and visible changes. Compare these with the messages that are actually available. Do not select a supposed final version solely because its filename or file date looks newer; the scan does not automatically reconstruct the order of every design revision.
The supported phone is connected but the recovery option is unavailable
Confirm that you are using Windows, then check the detected Xiaomi 17 Ultra, Android 16 and kernel 6.12.23 details. Follow the displayed connection guidance. If the option remains unavailable, provide those details and the exact message to Dr.Fone support without changing the phone's firmware or clearing LINE storage.
How to use Dr.Fone - Data Recovery (Android)
Dr.Fone - Data Recovery (Android) gives you a focused way to look for missing LINE instructions and the files that make them useful. Its Windows-only Advanced Recovery scans a connected supported Xiaomi 17 Ultra without requiring a previous LINE backup, lets you preview discoverable conversations and attachments, and saves your chosen results to a PC. For a custom pattern, that means checking the explanatory wording as well as the image or document, rather than relying on a photo alone.
- Inspect available LINE conversation text for units, references and later corrections.
- Preview LINE Attachments separately to identify relevant photos, videos and pattern files found by the scan.
- Select useful records for a PC copy without saving unrelated conversations.
Scan Android phones and tablets directly.- Preview and recover only what you want.
- Supports WhatsApp, photos, videos, contacts, and more.
- Works with 6000+ Android devices.
Follow the official Advanced Recovery workflow
Step 1 Open Advanced Recovery and connect Xiaomi 17 Ultra
Launch Dr.Fone on Windows and open Toolbox > Data Recovery. Choose Android > Recover Android Data, select Advanced Recovery and click Start Scan. Connect the supported Xiaomi 17 Ultra with a USB cable when prompted and follow the on-screen instructions until it is detected.
Step 2 Select LINE app data
Choose LINE from the available app-data categories and click Start Scan. This selects the app whose conversations and shared material you want to inspect.
Step 3 Keep the phone connected during the scan
Allow Advanced Recovery to scan while the USB connection remains stable. To stop, click Cancel before disconnecting. If the phone is temporarily unresponsive after scanning or recovery, follow the restart instructions displayed by the product.
Step 4 Preview LINE text and LINE Attachments separately
Choose LINE in the results sidebar to review available conversations. Use search or filters where available to locate the maker's exchange. Then open LINE Attachments to inspect available pattern files, annotated photos and videos separately. Select the records that address your missing instructions.
Step 5 Save selected records to your PC
Click Recover and follow the prompts to choose a folder on your computer. Complete the save, then open the saved output to check the selected messages and attachments. These are PC copies; the workflow does not place them back into LINE on the phone.
Conclusion
For missing pattern instructions, recovering the explanation can be as valuable as recovering the attachment. Dr.Fone - Data Recovery (Android) helps you inspect available LINE wording, review the associated photos or files, and save selected useful records to your PC. Download the Windows version, connect your supported Xiaomi 17 Ultra and start the LINE Advanced Recovery workflow.
FAQ
1. Can I recover deleted LINE messages on Xiaomi 17 Ultra without a backup?
Dr.Fone - Data Recovery (Android) provides a local device-scan route for the listed Xiaomi 17 Ultra configuration: Android 16 and kernel 6.12.23. No previous LINE backup is required for this scan. You can preview what it finds and save selections to a PC, but the presence of a support entry does not guarantee that a particular deleted message remains recoverable.2. Will Google Drive or Premium Backup recover instructions deleted before I backed up?
No. LINE's Standard Backup on Android requires a usable backup made before the deletion and covers text messages rather than the full set of media attachments. A backup made afterward cannot recreate the missing instructions. LINE also states that Premium Backup cannot roll back a manually deleted chat. Neither is the no-backup scan described here.3. Can I recover deleted LINE photos and videos as well as a pattern file?
Inspect LINE Attachments for the photos, videos and files available in the scan. Save the items you can identify and access. An unavailable or expired original is not guaranteed to exist locally, and a recovered picture does not automatically restore the messages that explained it.4. Does the tool determine which measurement or pattern version was correct?
No. It provides available records for you to review; it does not validate measurements, identify the accepted pattern or reconstruct missing decisions. Keep actual recovered wording separate from your interpretation, and confirm any unresolved detail with the maker.
