Xiaomi Official Patch NV Fix NV Error & Restore IMEI CPID Method
📲 Xiaomi Official Patch NV – Fix NV Error & Restore IMEI (CPID Method)
If you’ve been around Xiaomi phones long enough, you’ve probably seen that scary NV error or the case where the IMEI just vanishes. When that happens, the phone loses its signal and, honestly, it feels dead. You can still turn it on, but no calls, no network, nothing. Pretty useless.
Now, the good part is there’s a small tool that can fix this headache. It’s called XiaomiOfficialPatchNv, made by MikoForce. The tool uses the official CPID method to restore IMEI and patch NV. I actually tested it myself on Xiaomi Lake and Pond models — and yes, it worked.
🔹 How does CPID/CHIPID restore work?
When you connect the phone, the tool reads the CHIPID (CPID). This is like the phone’s fingerprint — unique for every motherboard
Then it shows a panel with all the important stuff:
- Device codename (example: pond or lake)
- CPID confirmation
- Original numbers: IMEI, MEID, Wi-Fi MAC, Bluetooth MAC
- You can even check these against the label on the phone box.
- The tool then writes those numbers back into the NV partitions. Since it’s linked to your phone’s CPID, it’s safe — you won’t end up writing someone else’s IMEI by mistake.
- After reboot, the radio services restart, and your IMEI plus network are back like nothing happened.
- 🔹 Why CPID method is better
- It’s official and reliable.
- Works even after motherboard change or full firmware flashing.
- Avoids the risk of messing up IMEI with random third-party tools.
