I have roughly 800 JPG and MP4 files that were shot on my Samsung A55. After moving them from the phone’s internal storage to a micro-SD card they stopped opening: Windows Photos reports “It looks like we don’t support this file format.” File sizes are intact, so the data is still present—headers or file structure appear to be damaged. I already ran a couple of well-known recovery or repair utilities, but they made no difference. Before I commit to a full-blown hardware lab, I want a specialist approach that goes deeper than off-the-shelf software and tells me whether a clean logical repair is still possible. What I need from you • Analyse sample JPG and MP4 files, demonstrate they can be repaired. • Restore the remaining files (about 800) at original resolution and quality. • Document the root cause and the exact steps or tools you used so I can prevent this in the future. • If you determine that only a professional lab service can finish the job, outline the options, likelihood of success, and cost implications so I can decide. Acceptance criteria 1. At least 95 % of photos open normally in any standard viewer. 2. Repaired videos play end-to-end in VLC without visible artefacts or audio desynchronisation. 3. A concise report summarising findings, recovery rate, and methodology. Feel free to use whatever toolkit you trust—hex editors, PhotoRec, ffmpeg, custom Python scripts—as long as you work on verified clones of the originals and preserve metadata wherever possible. I can supply sample files immediately so you can confirm feasibility before tackling the full batch. Files on this link: [login to view URL]

Hi there, A sample result will be provided before awarding the project. I can help analyse your damaged JPG and MP4 files at a deeper level than standard recovery utilities and determine whether the issue is related to corrupted headers, filesystem transfer damage, incomplete writes, or structural metadata problems from the SD card migration process. Since the file sizes remain intact, there’s a strong possibility that logical repair and reconstruction may still be possible without requiring immediate hardware lab recovery. I can first test a batch of sample files to confirm repair feasibility, then proceed with structured recovery while preserving original quality and metadata wherever possible. I’ll also provide a concise report explaining the likely cause, recovery success rate, and recommendations to help prevent similar corruption issues in the future. Please send a few sample JPG and MP4 files so I can evaluate the damage and confirm the best recovery path before handling the full collection. Thanks!

I understand you're facing a common data corruption issue similar to scenarios where file system metadata becomes desynchronized during transfers, leading to unreadable media files despite intact file sizes. My experience with forensic data recovery and file system analysis allows me to address precisely this type of logical corruption. My approach will involve a multi-stage process starting with a low-level sector-by-sector imaging of the micro-SD card to preserve the original data state. I'll then use specialized hex editors and file carving tools (like PhotoRec/TestDisk for initial scans, and then custom Python scripts leveraging libraries like `scapy` for deeper packet-level analysis if network transfer corruption is suspected, or `libjpeg` and `ffmpeg` for targeted header reconstruction) to analyze the file structures. The goal is to identify and repair damaged file headers and critical metadata segments for both JPG and MP4 files, bypassing the standard Windows Photo app limitations. Could the issue be related to a specific transfer protocol or interruption during the move to the SD card? I'm confident I can determine the extent of logical repairability for your Samsung A55 media. Let’s connect to discuss the specifics and the diagnostic path forward.

Dear Client, Greetings!! I am Rojan Upreti, with experieence in data recovery, file repair, Python scripting, media restoration, and low-level troubleshooting. I can analyze your damaged Samsung A55 JPG and MP4 files to determine whether the corruption is related to broken headers, filesystem transfer issues, or SD-card write corruption, and attempt advanced logical recovery beyond standard recovery tools.. using specialized approaches such as hex-level inspection, ffmpeg-based reconstruction, metadata repair, PhotoRec workflows, and custom repair scripting, I can test sample files first, restore the remaining media while preserving original quality and metadata as much as possible, and provide a detailed recovery report with prevention recommendations. If deeper hardware-level recovery is required, I cna also guide you regarding professional lab options, expected recovery probability, and cost considerations before you proceed further. Best Regards, Rojan

Hello, Could you share the specifics about the repair utilities you’ve already tried? Understanding what has been attempted will help me avoid redundant efforts. I aim to analyze the sample JPG and MP4 files to verify their repairability before moving on to the full batch. My approach will involve using specialized tools and techniques beyond standard software to attempt logical repairs while preserving the original resolution and quality. Additionally, I’ll document the root cause and steps taken, so you can take preventive measures in the future. To clarify a few points: 1. How urgent is this project? 2. Are there any specific file retrieval settings or conditions you prefer? 3. Do you have any other files that you’d like me to analyze before initiating the full restoration? 4. Would you want a detailed report on the recovery process to understand the methodologies used? Cost and timeline will be placeholders until I have evaluated the files’ condition. Looking forward to your response! Relevant Portfolio: • https://www.freelancer.com/u/amjad2 Best Regards, Amjad Iqbal
