The main discussion still shows a telescope photo, but the reply explaining which adjustment finally helped has disappeared. Before repeating an earlier suggestion, you want the actual follow-up, not a short summary or a similar-looking image. If you need to recover deleted LINE messages on Google Pixel 9 Pro XL without a backup, start by separating a reply stored elsewhere in LINE from text that was really deleted.
Dr.Fone - Data Recovery (Android) offers a focused route for supported devices: read the LINE conversations found during scanning, inspect photos, videos and files separately, and save the useful selection to a PC. The checks below help identify the missing information first, so your recovery review has a clear target.

Before you start
Use the Pixel 9 Pro XL configuration, not another Pixel record
The supplied support record names Google Pixel 9 Pro XL with Android 15 and Kernel 6.1.157. Keep those conditions together when checking your phone's software information and the product's device-detection prompts. The base Pixel 9 Android 14 record is not a substitute. Advanced Recovery is Windows-only and saves selected discoverable results to a PC, not back into the phone's LINE chats.
Keep the original local data available
Prepare a Windows computer, a USB data cable and a private output folder. Leave LINE installed; avoid clearing its storage or cache, deleting messages, changing phones or following bootloader-unlock, flashing or Root tutorials as recovery experiments. Follow only the product's displayed connection and access instructions for the supported configuration.
Identify the kind of conversation
OpenChat is available in Japan, Taiwan and Thailand, and the optional thread check applies only where the existing room and feature are accessible. It is not a menu for every ordinary friend or group chat. Standard Backup requires a copy made before deletion and covers text rather than original media; Premium Backup is not a rollback for manually deleted chats. Neither is the no-backup scan method below.
Check an existing OpenChat thread before calling its replies deleted
Use this retained-content check if the missing troubleshooting exchange happened inside an OpenChat you can already access. For an ordinary chat, or when this feature is unavailable, move to the results table and device scan.
Step 1 Open the room's thread list, not a new conversation
In the existing OpenChat room, select the Threads icon at the upper right. LINE's Japanese mobile help describes a thread as a separate conversation space based on a room message. Inspect the existing list; do not create a replacement thread, send a test reply or leave and rejoin the room.
Step 2 Compare Favorites with All
The Favorites view shows favorited threads, while All shows the room's full thread list. A thread you created or replied to is automatically favorited, but a discussion you only read may not be in that subset. Open the relevant available thread and read the actual replies, including whether the writer reported a result or merely suggested a test.
Step 3 Read the source instead of relying on an AI summary
LINE states that OpenChat thread messages are not included in its AI message summaries. An absent sentence in a summary therefore does not establish deletion. Preserve any useful accessible wording separately from your own recollection; if the actual message is missing, note its subject, approximate date and accompanying image for the scan review.
- The official thread rules say new threads cannot be created from messages sent more than 48 hours earlier, and messages cannot be sent in threads more than three weeks after creation. Those are creation and sending limits, not a promise that content is automatically deleted at those times.
- A thread is deleted if its originating message is unsent or removed from every member's history. Switching the list view does not undo that deletion, and Dr.Fone's general LINE support is not a guarantee of OpenChat thread or summary reconstruction.
Which result actually answers the missing follow-up?
| What you find | Useful result | Next decision |
|---|---|---|
| The reply in an existing thread's All view | The retained discussion can be read now | Separate a reported improvement from an untested suggestion; no deleted-message recovery was needed |
| A room summary without the thread reply | Only the summary's included content | Read the actual thread if accessible; do not fill its omission from memory |
| Readable LINE conversation records in the scan | Available wording and surrounding context saved to PC | Select the specific follow-up rather than treating every similar keyword as the answer |
| Only a photo, video or file in LINE Attachments | A useful visual or reference copy | Keep it separately; it does not supply the missing explanation or prove which suggestion worked |
Common problems and fixes
The thread is absent from Favorites
Inspect All in the existing thread list before concluding it was deleted. Favorites is a subset, not a deleted-content index. If the original thread is no longer available, retain the distinction between an accessible ordinary chat record and a missing OpenChat thread.
A recovered message says 'try this' but not 'this worked'
Read the available surrounding exchange and look for the actual follow-up, date and subject. A proposed adjustment is not an observed result. Save the proposal as a proposal if that is all you find, alongside any usable reference media.
Advanced Recovery is not offered for the connected phone
Check that you are using Windows and the exact Pixel 9 Pro XL Android 15/Kernel 6.1.157 configuration. Record the displayed compatibility or connection message for Dr.Fone support rather than changing firmware to imitate a different listed Pixel.
How to use Dr.Fone - Data Recovery (Android)
Dr.Fone - Data Recovery (Android) gives you a Windows-only Advanced Recovery workflow for looking beyond the currently visible chat on a supported Pixel 9 Pro XL. Scan LINE app data, read available conversation text, preview photos, videos and files in LINE Attachments, and save selected results to a PC. This is especially useful when you need the actual follow-up wording rather than another copy of the original reference image.
- Conversation review helps distinguish a question, proposed fix and later reply when those records are found.
- Separate attachment previews let you identify the relevant image or clip without assuming it contains the missing discussion.
- Selective PC saving keeps the useful text and supporting files together for your own review outside LINE.
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 the Pixel
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 Pixel 9 Pro XL by USB when prompted and follow the on-screen instructions until it is detected.
Step 2 Select LINE app data
Choose LINE among the app-data categories and click Start Scan. The guide requires WhatsApp and WhatsApp Business to be scanned separately from the other categories; that does not create a separate-only rule between LINE and other non-WhatsApp categories.
Step 3 Keep the phone connected during scanning
Wait while Advanced Recovery scans the selected data. If you must stop, click Cancel before disconnecting the cable. If the phone is temporarily unresponsive after scanning or recovery, restart it as instructed on the product screen.
Step 4 Read LINE results and inspect attachments separately
Select LINE in the sidebar to preview available conversations. Use search or filters where available to locate the relevant exchange and read its actual wording. Then select LINE Attachments to review found photos, videos and files separately. Select only records that help answer your missing follow-up.
Step 5 Save the selected records to your computer
Click Recover and follow the prompts to choose a folder on your Windows PC. Save the selected available results there for review. The output is a PC copy, not restored thread membership, an interactive OpenChat thread or messages inserted back into LINE.
Conclusion
For a supported Google Pixel 9 Pro XL, Dr.Fone - Data Recovery (Android) helps you look for the actual missing conversation, inspect relevant photos and files, and preserve a focused selection on your PC. Download the Windows version, connect your compatible Pixel and start the guided LINE scan to bring useful follow-up wording and supporting references back within reach.
FAQ
1. Can I recover deleted LINE messages on Google Pixel 9 Pro XL without a backup?
Dr.Fone - Data Recovery (Android) provides a local device-scan route for supported configurations without needing an earlier LINE backup. Use Advanced Recovery on Windows, preview the available LINE and LINE Attachments results, and save selected found items to a PC. Recoverability depends on what the scan can still discover.2. Does a missing OpenChat summary sentence mean the reply was deleted?
No. LINE's thread help specifically says thread messages are not summarized by the AI message-summary feature. Where the existing room and thread feature are available, inspect the actual thread and its All list instead of using the summary as a complete record.3. Do the 48-hour and three-week thread limits set a recovery deadline?
No. LINE describes 48 hours as the limit for creating a thread from a sent message, and three weeks as the period after thread creation beyond which new messages cannot be sent. Those rules do not establish a deleted-data scan deadline or guarantee that older replies remain available.4. Can the scan rebuild an OpenChat thread and all its media?
Do not assume that. The documented workflow previews available LINE conversations and LINE Attachments and saves selected found data to a PC. It does not promise complete OpenChat thread structures, restored deleted originating messages, regenerated summaries or unavailable original media.5. Which Pixel 9 Pro XL software conditions apply?
The supplied record for this exact model lists Android 15 and Kernel 6.1.157. Do not borrow the base Pixel 9's Android 14 conditions or a Fold variant's extra kernel. Use the actual detected configuration and product instructions before proceeding.
