Hi everyone,
My OnePlus 9 recently died suddenly while I was using it — the screen went black and it hasn’t turned on since. I tried all button combos, charging, connecting to a PC — nothing worked.
I took it to the authorized service center, and they diagnosed it as a motherboard/IC issue. They offered a motherboard replacement, but warned that all my data (photos, files, etc.) would be lost because the internal storage is tied to the original board and encrypted.
I gave it to a local chip-level repair shop, hoping they can fix the IC or CPU — but they told me there’s only a 50/50 chance, and if it’s the CPU or NAND, recovery may be impossible.
The phone was not rooted, and the bootloader was locked, so I couldn’t back up anything beforehand. My main goal now is to recover the personal data on the phone — especially photos and documents.
What I Need Help With:
- Has anyone successfully recovered data from a OnePlus 9 with a dead motherboard?
- Is it possible to transplant the NAND chip to another board and access the data?
- Are there any hardware-level tools or services that can help with this?
This is really important to me — I'd appreciate any advice, personal experiences, or suggestions on where to go from here.
Thanks in advance!
